Cranberry Lake Park: Prepping for Winter, Sowing for Spring

One of the many spots where meadow meets woods at Cranberry Lake Park

Cranberry Lake Park, with its varied habitats, gives an autumn visitor lots of possibilities. In October, the lake hosts huge bobbing rafts of water birds, feeding and resting on their way south. The grassy trails lead you to expansive meadows covered now by the soft gray of seeding goldenrod, where migratory birds converse in the bushes while harvesting seed. Or you can choose the shady Hickory Lane to the west or the dappled light of the maple forest to the north if you’re in the mood for a woodland walk.

My visits were scattered throughout the month –  unusually warm days early on, a sunset hike one breezy evening, and finally a cold, rainy morning right before first frost. Each time I rediscovered how sensibly nature prepares for a winter rest and a bountiful spring. 

 

 

Cranberry Lake Itself  – A Thwarted Kingfisher, a Remarkable Grebe, and Diving Ducks of All Kinds

The edge of Cranberry lake at the end of an eastern trail.

Cranberry Lake welcomes all kinds of water birds as they begin their long journeys to southern climes. One cold, wet morning, I watched a bird hovering vertically high above the water, head down, scanning the surface below. Suddenly, it gave a loud rattling cry and headed for a leafless tree near the shore. An agitated male Belted Kingfisher (Megaceryle alcyon) shouted its noisy call from a bare limb. Perhaps he was put out by not spotting prey from that perch either!

This male Belted Kingfisher had one slate blue belt on his chest. The female has a chestnut brown belt and a blue one.

A small Killdeer (Charadrius vociferus) flew in to probe the edge of a mud flat, landing near a Canada Goose (Branta canadensis). Quite an odd couple!

A Killdeer shares a mud flat in the lake with a Canada Goose.

Killdeer are wading birds, being Plovers, but I’ve most often seen them in barren fields, either scurrying along scaring up insects or keening in flight to distract predators.  This one, though, looked right at home as it probed the mud for insect larvae or other aquatic prey before beginning migration.

Far out on the lake, a huge mixed flock of migrating ducks and other water birds, well over 200 of them, floated on the surface, foraged for food, or slept and preened on the mud flats in the shallower parts of the lake.

After studying the photo magnified, Ben guessed that most of the birds were Ring-necked Ducks (Aythya collaris) which are diving ducks. Unlike mallards and other dabbling ducks who simply tip upside down to feed, diving ducks have legs set far back on their bodies.  As a result, they need to run across water, wings flapping,  to get into the air and are awkward on land – but they dive, feed and swim underwater with ease!

(Since most of the Cranberry Lake flock was far from shore, the closeup photos of diving ducks below are all from inaturalist.org photographers. My thanks to all of them and to Creative Commons where they license their work.)

Two other diving ducks that Ben thinks may have been in this flock include Redhead (Aythya americana) which are so social that they’re also referred to as “rafting ducks” and  Lesser Scaup (Aythya affinis). According to the Cornell Ornithology Lab, Lesser Scaup chicks “are capable of diving under water on their hatching day, but they are too buoyant to stay under for more than just a moment. By the time they are 5 to 7 weeks old they are able to…swim underwater for 15-18 meters (50-60 ft).” Here’s a wonderful closeup of a Redhead by photographer lonnyholmes and a Lesser Scaup photo by photographer Paul Sullivan. (Hover cursor for captions; click on photos to enlarge.)

Far out in the lake, through my binoculars, I also spotted Bufflehead, another diving duck,  on their way from the boreal forests of Canada and Alaska, where according to Cornell, they “nest almost exclusively in holes excavated by Northern Flickers and, on occasion, by Pileated Woodpeckers.” Unfortunately the male and three female/juvenile Bufflehead that I saw at were too far for my longest lens to reach clearly. So on the left is my distance photo from Cranberry Lake (click to enlarge) and  on the right is a closeup from a  photographer at inaturalist.org who uses the name dlbowls showing the male’s dark head iridescent in the sunlight.

Feeding alone on a rainy morning, the solitary  Pied-billed Grebe (Podilymbus podiceps) dove repeatedly into the gray surface of the lake. Modest brown this time of year,  these grebes bills turn white with a neat black band in breeding season. Pied-billed Grebes control their buoyancy by trapping water in their feathers. According to Cornell Lab, this allows them to escape danger by doing what children might call “belly smackers” – “plunging with head and tail raised above the belly, making a splash. They can also dive head first, or simply sink quietly out of view, leaving no trace. Parents dive with young clamped under their wings … These grebes often avoid danger by submerging, crocodile-style, with just the eyes and nostrils above the surface.”

The little grebe at Cranberry Lake gave me a brief demonstration of the submerging tactic –  first trapping water in its feathers , then settling back down on the water, and finally beginning to submerge like a little submarine.  What a trick!  I’m very taken with this little bird.

Wide, Sunny Meadows Surrounded by Autumn Color

A meadow on the north end of the park

On the trails that lead toward the meadows, small brown birds dash from bush to bush or dart down into the grass.  Some are tiny migrators who might appear modest and plain until you see them through binoculars or a camera lens. Chubby White-throated Sparrows (Zonotrichia albicollis), with their yellow “lores” and striped heads, hung out in small flocks, keeping in contact with soft seep calls.

The White-Crowned Sparrow has yellow “lores” – spots in the corners of its eyes.

Another brown migrant paused in the bushes along the trail from the lake – the Hermit Thrush (Catharus guttatus). These normally solitary birds are often quite secretive – hence the name, perhaps? They’re well-dressed hermits, though, with their chocolate back, spotted breast and white eye ring. And during migration, they do sometimes forage with or near other small birds.

The Song Sparrow (Melospiza melodia) is silent now, no longer burbling its song from high in a bush as it did this spring and summer. In fact, this one glowered from the bare branches, seeming a bit put-out by my presence. Or maybe it’s just irritable about having to migrate, though  it will only travel a short distance to the south.

At the edge of a small meadow, a year-round resident, the American Goldfinch (Spinus tristis) pecked delicately at the seeds of Common Evening-Primrose (Oenothera biennis) that nicely complemented its muted gold.

An American Goldfinch fed in its modest winter feathers.

And another year ’rounder, the Northern Cardinal (Cardinalis cardinalis) stared from the drooping vines of Oriental Bittersweet (Celastrus orbiculatus), an aggressive, invasive plant that strangles, shades out and topples trees. Two trees along the trail had fallen recently due to masses of this vine in their canopies. Those orange and red fall fruits are disastrously appealing to birds, who spread their seeds far and wide.

On my early October visits, insects were still very much in evidence. One warm October afternoon, a busy group of adult and juvenile Large Milkweed Bugs (Oncopeltus fasciatus) fed eagerly on the seeds of Common Milkweed (Ascelpias syriaca) in a southern meadow. The large beetles below are adults accompanied by the mostly red juveniles. They eat milkweed seeds by injecting saliva through the seed’s surface which liquifies it so it can be sucked through their straw-like rostrums. Milkweeds produce lots of seeds, so luckily these beetles, though destructive to individual pods, don’t really do a lot of damage in a season. And they are kind of jazzy looking, don’t you think?

Juvenile and adult Milkweed Bugs on a Common Milkweed.

Red-legged Grasshoppers (Melanoplus femurrubrum) mate in the autumn and lay their eggs in the earth. The eggs won’t finish developing until spring, when the first nymphs emerge. They’ll molt 5-7 times during the summer before they are fully adult, like this pair on a grassy trail.

A female (left and larger) and male Red-legged Grasshopper will lay eggs that will hatch next spring.

As October moved on, the goldenrods – Canada Goldenrod (Solidago canadensis) and late blooming Showy Goldenrod (Solidago speciosa) – began to seed, casting a silver-brown patina over the meadows.

Despite the cooler days, the small Autumn Meadowhawk (Sympetrum vicinum) still glided along the meadow paths, stopping on a fallen Canada Goldenrod stem to warm its wings in the autumn sunlight. The yellow-orange blush on the wings near the thorax is a distinguishing field mark. Autumn Meadowhawks fly later than most other species in our area, but are usually gone by early November, having laid their eggs along the lake’s shoreline.

The Hickory Lane and Wooded Wetlands – Filtered Light, Foraging Nut Eaters, a Frog and Puffballs

The Hickory Lane at sunset

Woodland walks are magical in the early morning or just before sunset. The light filters down through a golden shimmer of falling leaves and sometimes sets a crimson leaf aglow.

A Silver Maple leaf (Acer saccharinum) in the northern forest  set aglow in morning light.

On a warm walk in early October, the bright yellow caterpillar of a Spotted Tussock Moth (Lophocampa maculata) caught my eye within the dry leaves on the Hickory Lane. Such a fancy caterpillar! Research in Caterpillars of Eastern North America seems to indicate that  it’s the middle instar of the Spotted Tussock moth because in earlier stages, the end sections of this yellow caterpillar are completely black – but I’m open to correction by more knowledgeable readers!

The caterpillar of what I think is a Spotted Tussock Moth

An Eastern Chipmunk (Tamias striatus) on the Hickory Lane basked in the sunset, perhaps resting from a long day of ferrying nuts in its cheeks to stock its underground burrow. It won’t hibernate, but when it wakes periodically from its winter torpor, it will need a little sustenance before snoozing again.

An Eastern Chipmunk rests from its seed and nut-gathering labors before winter.

A Gray Squirrel (Sciurus carolinensis) dashed quickly up a tree on the Hickory Lane (in this case, it’s the black morph). And nearby, an American Red Squirrel (Tamiasciurus hudsonicus) did the same. I wondered if they had enjoyed some of the hickory nuts that were neatly opened on a fallen log not too far away.

Almost invariably, curious deer emerge at the edge of the woods, and they too are putting on weight for winter. They eat lots of nuts, including plenty of acorns, this time of year. Their love of acorns in the fall and saplings during the winter can make it harder for our oak forests to regenerate. This doe looks like she’s definitely eaten her share and is ready for cold days ahead!

A well-fed doe foraging for nuts before winter arrives.

In a pond hidden in the trees, a Muskrat (Ondatra zibethicus) had built a roomy “push-up” den in which it can eat above the water line. Muskrats don’t hibernate, but spend the winter cruising very slowly beneath the ice. What appears to be a hole is probably just plant matter or mud, since muskrats generally enter their push-up dens from under the water through a tunnel that leads up to a cavity at the center.  According to Wikipedia, “In snowy areas, they keep the openings to their push-ups closed by plugging them with vegetation, which they replace every day.”

Near that woodland pond in late October, a tiny masked Wood Frog (Rana sylvatica) literally sat “like a bump on a log,” staring off into the distance, partially lit by the green light of a leaf. Wood Frogs love forested wetlands like this during the summer. But this little frog may be preparing for winter. It will move upland, away from the water, burrow under leaves or a log. Then most of the water in its body will freeze solid, and its breathing and heartbeats will stop! But it will thaw in the spring and go right back to the pond to mate. Hope this little one finds a cozy spot before long.

The astonishing Wood Frog freezes solid in the winter and thaws out in the spring.

On a fallen long nearby, my husband and I came across  a colony of Puffball Mushrooms (division Basidiomycota) just as we did last year. These stalkless mushrooms would disperse spores on their own, of course, but I asked my husband to poke a couple in order to catch the brownish cloud of spores escaping through their tiny apertures. Wikipedia says falling raindrops disperse puffball spores in a similar way.

On my last visit just before first frost, under moist trees in these wooded wetlands, the Sensitive Ferns’ green, leafy, sterile fronds (Onoclea sensibilis) were already withering in the dropping temperatures. But the separate fertile fronds, covered in brown beads called “sori” that contain next year’s spores, stood erect in the grass beneath the trees.

Quietly Prepping for Winter and Another Spring

Cranberry Lake Park, like all of nature, provides testimony every autumn that the year is not “dying” as is so often said of this season. On the contrary. At every turn in the trails, nature is sensibly preparing for winter and sowing for spring. Yes, plants wither – but their seeds, stems, and roots wait within the soil for warm spring light. Gray-brown bracken will eventually fall, nourishing the soil in which those seeds can grow. Bright leaves fade and fall, of course, but only because trees are in “dormancy,” resting, slowing their metabolism, preserving themselves for next spring’s surge of growth. Some insects migrate, others winter-over under bark or within plants, while still others perish, leaving behind eggs which bide their time beneath the earth. Birds fly south, frogs burrow under logs, and animals of all sorts settle into winter quarters. Nature doesn’t resist change. It simply adapts to it, with every intention of burgeoning forth with gusto in the spring. We humans probably do best when we follow nature’s lead by just letting nature take its course –  preparing for longer nights and colder days, while confidently sowing seeds – both literally and metaphorically – for a future spring.

Bear Creek Nature Park: Young Birds, a Tiny Forager in Disguise and So Many Wildflowers!

Boneset and Joe Pye in the Eastern Meadow at Bear Creek

Late summer wildflowers nodded and swayed in the meadows, woods, wetlands and native gardens at Bear Creek this August. Monarch butterflies paused on the blossoms, competing mostly with industrious native bumblebees. And all over the park, young birds were feeding on their own – or in a few cases, still getting fed by doting adults. In the center pond, a tiny creature foraged in disguise!  

Blog post and photos by Cam Mannino

So take a wander along the trails, as goldenrod transforms the park from green to gold, and enjoy the bright beauty of summer’s last hurrah!

 

Like Some Human Youngsters, A Few Avian “Adolescents” Stick Close to Mom or Dad

A young Eastern Kingbird (Tyrannus tyrannus) hid in a shrub in the eastern meadow, insisting loudly about being fed.  No parental response was forthcoming from the adult on a shrub some distance away. So eventually, the youngster ventured out into the field, looking about with curiosity. Seemingly satisfied with this move toward independence, the adult flew in to feed the youngster. And then they shared the bush a while until the adult flew farther off again. (Click on slideshow’s pause button for captions.)

Two groups of Mallards (Anas platyrhynchos) were escorting their young around the Center Pond. In one group, two males and a female floated along with a small juvenile. The males are now in their late summer “eclipse plumage” which makes them look very much like the females – except that the males have yellow bills, while females’ bills are orange and black. The males will change back to their glamorous, iridescent green head feathers later in the fall when Mallards choose their mates for next spring. I guess these two males on the right were sticking close to this female just in case she made an early decision!

Nearby, a female Mallard escorted her four youngsters with no male attention at all.

A male Northern Cardinal (Cardinalis cardinalis) seemed remarkably calm at my approach as he concentrated on gathering seeds in his beak. Usually they dash off at the first sight of me when they’re on the ground. He wasn’t crushing the seeds, so I assume he had a nest nearby since cardinals can have up to four broods in a season. That’s a lot of parenting in just a few months.

A male cardinal who seemed to be gathering seeds to take to his young rather than eating them right away.

A male American Goldfinch (Spinus tristis) plucked buds from native Canada Goldenrod  (Solidago canadensis) which is just beginning to bloom. He may have been feeding his young as well, since this is the nesting season for goldfinches.

While Adults Molt, Young Birds Forage on Their Own

Many bird species molt from mid-August until mid-September, including Field Sparrows, Downy Woodpeckers, House Wrens and many others.  The Eastern Kingbird, featured feeding its young above, doesn’t molt until it reaches its winter territory in South America. It’s occurred to me that since birds go into hiding during the molt, perhaps their young have to be a bit more independent sooner than other birds. Just a guess. In any case, a lot of young birds are out and about, clumsily trying to forage on their own.

I saw what I think is an adult Song Sparrow (Melospiza melodia) just beginning its molt. The bird’s feathers looked oddly fluffed out and it was picking at its breast in a persistent way. It might be a male since they molt a bit earlier than females. Below, a group of young song sparrows hopped along the trail, seeing what they could find in the grass before flying up into small trees nearby.  (Click on photos to enlarge; hover cursor for captions.)

Downy Woodpecker adults (Picoides pubescens) are molting now too. The Stokes Guide to Bird Behavior (Vol II) says “[Downy] Fledglings in general can be told from adults by the clearly new, white feathers on their breast. Adult have gone in and out of the nest hole hundreds of times by this stage and look very worn, with bits of black showing through their white breast feathers.” The feathers on the young female I saw looked wonderfully fresh as it tried to drill into a branch, so I’m guessing it’s a foraging juvenile.

Down at the Center Pond, a Green Heron rested calmly on a log. Since spring, I’ve repeatedly seen a Green Heron in that very place, so I’m thinking it’s a mature bird. Cornell contends that Green Herons are sometimes found in colonies. But I’ve never seen more than one of these solitary birds at a time.

The same heron flew up onto a bare limb, staring into the water.

Two other solitary birds could have been adults or juveniles. It’s hard to distinguish with the House Wren and the Black-capped Chickadee once they’re out on their own. The House Wren may have been a youngster since it was clearly curious, but the Chickadee appeared to be a sophisticated contortionist as it probed a stick for insects.

Glorious Wildflower Color, Exuberant Vines and a Few Pretty-but-Toxic fruits in the Woods and Shady Wetlands

Though wildflowers are not generally as numerous on the shady paths of Bear Creek, you don’t want to miss them. So keep an eye out for their exotic shapes and vivid colors shining out of the greenery as you make your way, especially near wetlands. I just learned from Wikipedia that the Jack-o’lantern mushrooms (Omphalotus olearius) below are even bio-luminescent and their gills glow faintly green in the dark when they’re fresh! Hence the name, eh?

Native Wildflowers and Grasses Bask in the Sunlight of the Meadows and Native Gardens

A spray of Purple Coneflowers in one of the native gardens

In the native gardens, the center of the parking lot, and scattered across the sunny meadows, native wildflowers bloom among the Canada Goldenrod and the Queen Anne’s lace. The monarchs seem to be enjoying them. A female sipped nectar from the Purple Coneflower and a male spread his beautiful wings on the Joe-Pye. (The field marks for males are bulges in the veins on their hind wings.) Here’s a sampling:

A Quarter-sized Creature Dons a Bubble Disguise

One cloudy afternoon, my husband spotted a very small clump of bubbles, green Water Meal  (Wolffia coumbiana) and Duckweed (Lemna minor) moving slowly around the water of the center pond near the dock.

A moving patch of Water Meal, Duckweed and bubbles on the Center Pond caught our eye.

At first only the yellow/green striped head of a tiny Painted Turtle (Chrysemys picta) peeked out of the bubbly mass.

The tiny head of a Painted Turtle emerged from the bubbly greenery floating in the pond.

At last, we could see this tiny creature – a turtle about the size of a quarter – who’d found a nifty disguise to wear while munching on the Water Meal and Duckweed greenery that covers the pond. I’m betting on this little one to survive to adulthood!

A Painted Turtle – about the size of quarter! – brings its head and shell into the sunlight.

Perhaps when this baby gets a little bigger, it can join the Painted Turtles who hang out on this log at the east end of the pond almost every warm day. Last Saturday, this group seemed to be doing a slow motion version of the Hokey-Pokey (“You put your left leg in, you put your left leg out”), except for that one member who is not quite with the program!

 The Delight is the Details

Western slope of Bear Creek in mid-August

Meadows like the one shown above on the western slope are an eye-full on a summer day. The sweeps of green, yellow and white against a blue sky soothe the spirit like a cool hand on a fevered brow.  Soak it in.  You can feel yourself unwinding.  Then look a little closer.  So much of the delight in nature comes from noticing small things – like the turtle in its bubble disguise, the scarlet cardinal flower shining in a shady wetland, or a parent bird feeding its young on a leafy branch. Like any great work of art, there’s always more to see in nature’s landscapes than what comes quickly to the eye. So perhaps spend a few quiet minutes looking down into the water or into the tall grass. Scan the treetops through your binoculars. The smallest discovery can add just a little more joy to a walk in the park.

Out and About in Oakland: Gallagher Creek Park – A Nature Oasis in a Busy Area

 

Viewing Platform GC
Viewing Platform at Gallagher Creek Park

I’ll admit that when I first visited Gallagher Creek Park, just east of Adams on Silverbell, I didn’t quite get it. It seemed like a rather ordinary, flat piece of land surrounded by a marsh. But luckily, I decided to look more closely and, as usual, the closer I look, the more nature shares with me. I’ve visited the park several times over the last month and each time I appreciate this little park more.

The stream flowing quietly through the grass beneath the viewing platform creates a cool, moist retreat for an abundance of birds and the special native plants that love wet feet. The Old Fields bloom with an astonishing variety of native wildflowers. Insects float and buzz between the blossoms. In short, this little park hosts an amazing variety of wildlife and plants with its combination of marsh, wet meadows and open fields (click here to see a map).  Let me show you just a sampling.

 

 

Gallagher Creek Itself:  A Haven for Birds and Wildflowers

The recently constructed viewing platform (thanks to Eagle Scout Jonathan Walling!) near Gallagher Creek allows visitors to watch the slow ripples of cool water flowing through the grass and trees. This gentle flow creates a soothing retreat that shelters creatures and plants of all kinds. According to three surveys by the Michigan Department of Natural Resources, Gallagher Creek is home to “one of the few remaining self-sustaining Brook Trout (Salvelinus fontinalis) populations in southern Michigan.”

After the last survey, though, they reported that the “gravel riffles and natural pools” had been silted by nearby construction, reducing the population from 300 Brook Trout per mile in 1998 to just 50 per mile in 2010.  (See Ben’s blog on this from 2015.) Native plants growing more abundantly at the edges of the park can act as a buffer and filter such sediment. Gallagher Creek runs northeast and enters Paint Creek at the Cider Mill in Goodison. If we want Brook Trout in our township, one way is to protect a cold water stream like Gallagher Creek.

Wetland Wildlife and Plants: A Riparian Corridor and a Marsh

Streams like Gallagher Creek create what’s called a “riparian corridor,” an area where the land meets a stream or river that not only filters and purifies water, but also provides habitat for a wide diversity of plants and wildlife. Antonio Xeira, our birder friend, spotted a  most impressive bird  near the creek. Here’s his photo of a Great Horned Owl (Bubo virginianus) who spends its days high up among the leaves of a Willow (probably black willow, Salix nigra) north of the stream. It’s not easy to see so I appreciate Antonio’s shot!  See that open eye?

A Great Horned Owl, photographed by Antonio Xeira, spends the day in a large Willow tree to the north of Gallagher Creek.

A much smaller visitor among the willows is what I think was a Willow or Alder Flycatcher (Empidonax species) that perched in the shadows to preen. ( It could also be a Eastern Wood-Pewee (Contopus virens), but I’ll leave that for you to decide. They’re very similar.) It was a hot morning and this little bird was very busy dealing with the gnats or mites that can bother birds as much as they can bother us humans this time of year!

The shade near the stream also provided a stopover for a busy House Wren (Troglodytes aedon).

This hard-working adult was foraging for her young in a nearby thicket of native Gray Dogwood (Cornus foemina), which provides lots of cover and a food source for all kinds of birds at Gallagher Creek.

Gray Dogwood GC
Stands of native Gray Dogwood provide shade, protection and a food source in several thickets around Gallagher Creek.

One morning, I approached the thicket to see if I could see the young wren.  Immediately, the adult starting her scolding call, chipping incessantly at me, probably both to ward me off and to tell her fledgling to stay back in the trees. I did finally manage to get a shot of the youngster who appeared to still be growing into its beak!

Back in May, Antonio also noticed the burrow of a Crayfish (superfamilies Astacoidea and Parastacoidea),  a creature that loves clear, cold water streams. In case you haven’t seen a crayfish, I include a photo of one that I saw in Bear Creek.  If you enlarge the photo by clicking on it, you’ll see it’s a female carrying eggs under her tail! Crayfish are daylight creatures who retreat to burrows at night. I can’t say which species is in either photo. We do have one invasive crayfish in Michigan, the Rusty Crayfish (Orconectes rusticus), which fishermen used to use as bait and which have affected populations of our native crayfish.(Hover cursor for captions; click on photo to enlarge.)

Moisture-loving wildflowers in pink, purple, white and yellow bloom among the tall grasses and reeds  at the edge of the stream. Here are three native flowers that are easy to spot in the park – Blue Vervain (Verbena hastata), Canada Goldenrod (Solidago canadensis) and Joe Pye (Eutrochium maculatum).

The moist ground even a bit farther out from the stream suits many plants. Tall Sunflowers (Helianthus giganteus) and Water Hemlocks (Cicuta maculata), both natives,  prefer to sink their roots in moist earth.

Of course, dragonflies make their home wherever there is water. I saw a mating pair of Ruby Meadowhawks (Sympetrum rubicundulum) making a wheel of their bodies in the wet grass one morning.  The female is retrieving sperm from the male’s abdomen where he placed it earlier.  And to the right is what I think is another female Ruby Meadowhawk perching near the edge of the stream. Meadowhawk dragonflies (family Libellulidae)are plentiful this time of year and tough to identify,  but fascinating to watch as they hunt along the creek.

This thumbnail-sized Skipper butterfly (family Hesperiidae), I’m guessing a Delaware Skipper (Anatrytone logan), paused delicately on a moist leaf as I approached the stream.  Isn’t it elegant with its striped legs and antennae, large eyes and deep orange wings?

Gallagher Creek Park also shares an emergent marsh with its neighbors to the east. This thriving area is slowly being cleared of the dreaded invasive, Phragmites (Phragmites australis), which is much too prevalent in the area. It’s an on-going project of Dr. Ben and the Parks and Recreation Commision. How wonderful to see natives like sedges (Carex species) and Joe Pye flourishing as that terrible invasive plant diminishes!

Wildlife and Plants in the Old Fields

In the spring and early summer, our sharp-eyed birding friend, Antonio, found two nests on open ground at Gallagher Creek. I wonder if these eggs hatched since they seem so vulnerable. On the left is a Killdeer’s nest (Charadrius vociferus) from late April. The name, by the way, comes from their call, not from their effect on deer! And on the right is  a Spotted Sandpiper‘s nest (Actitis macularius) in early June.  Thanks, Antonio!

Now birds whisk in and out of the leafy trees at the perimeter of the Old Field next to the parking lot – many of them juveniles or adults working at feeding them. The “miaou” of a young Gray Catbird (Dumetella carolinensis) caught my attention at the edge of the field.  And later hearing a “cluck,” I look up to see an American Robin (Turdus migratorius), perhaps a molting female adult or a juvenile losing its spots, perched at the top of a snag.

Chipping Sparrow (Spizella passerina) and a male House Finch (Haemorhous mexicanus) hung out together in the bushes one hot morning.

American Goldfinches (Spinus tristis) provide the soundtrack for Gallagher Creek right now. These cheery little birds are one of the few who sing as they fly! With every downward swoop of their undulating flight comes a short burst of song. Here’s a male that settled for a few moments in that Willow, again – a popular place to pause for many of the birds here.

Goldfinches mate in August because their favorite food source is available – thistle seed.  So they’re quite happy, I imagine,  that non-native Field Thistle (Cirsium arvense) established a large, plumed patch on the western end  of the loop path.

We appreciated being greeted by a relaxed Eastern Cottontail (Sylvilagus floridanus) when parking at Gallagher Creek one morning.  It seemed to be enjoying a bit of morning light after a long night of nibbling.

As Reg and I set out on the path, we were greeted by a sight I’d never seen before.  A Downy Woodpecker (Picoides pubescens) hung onto one of the huge non-native stalks of Common Mullein (Verbascum thapsus) in the Old Field. Downies eat both insects and seeds, so I guess it was just varying its diet

Closer to the water, this small bird fluffed its feathers as it settled in a bush. It looks a lot like the Willow Flycatcher but was a little bigger. So I’m guessing this is an Eastern Wood-Peewee (Contopus virens), but I can’t be sure!

I think from its size, this is an Eastern Wood-Pewee, but again, it could be a Flycatcher!

Among all the non-native wildflowers, like Queen Anne’s Lace and Spotted Knapweed in the Old Fields, many native wildflowers are increasingly making a home in the Old Fields here. In August of 2014,  Dr. Ben did what’s called a floristic survey of Gallagher Creek.  Of the 192 species he found on one day there, 131 were native!  Today they are more plentiful and healthy because Ben and his summer techs have eliminated many invasive shrubby plants and held repeated prescribed burns here. They plan to increase the native plant habitat in this park by planting native prairie species into the areas that were primarily non-native, invasive plants. The first phase of native plant installation will happen fall 2016, with a second round in 2017. Check out the sign on the west side of the driveway just as you enter the parking lot to learn more details.

In Bear Creek, Yarrow (Achillea millefolium) is an occasional plant, but  this summer, it grew in large swathes along the paths of the field near the parking lot at Gallagher Creek. Now, after the intense heat, it is turning brown and seeding for next spring’s crop.

Of course, native Common Milkweed (Asclepias syriaca) appears here and there, and is now producing its green, paisley-shaped pods. Along with more common Canada Goldenrod, another native called Grass-leaved Goldenrod (Euthamia graminifolia), flourishes as well. As I reminded readers last summer, Goldenrods do not cause “hay fever.” Their pollen is heavy and drops quickly to the ground. The sneeze-producing culprit that blooms at the same time is the wind-pollinated Ragweed (genus Ambrosia) which you can see if you click on the link.

Common Evening Primrose (Oenothera biennis) raises its graceful stems topped by yellow flowers among the grasses to the east of the park.  According to the Illinois Wildflower site (one of my faves), these flowers “remain open from evening to early morning, but will remain open longer on cloudy days. They have a mild lemony scent, and bloom from mid-summer to fall on mature plants. Long narrow seedpods develop, which split open from the top to release many tiny, irregular brown seeds. They are small enough to be dispersed by the wind, and can remain viable in the soil after 70 years.”  So if we keep caring for the land here, these night-blooming natives should be here for your grandchildren!

Common Evening Primrose blooms as the sun goes down until morning.

Out in the Old Fields, insects are busy in the late summer sun.  Carolina Locusts (Dissosteira carolina) spring into flight, their wings making a brown blur at your feet.

Clouded Sulphurs (Colias philodice) have a larger range of flight, feeding on taller plants like the Milkweeds and Coneflowers, but also on alfalfa or clover closer to the ground.

So, this modest little park is actually a rich oasis of native plants and wildlife along an important cold water stream  in the midst of the most developed area of our township.

The Parks and Recreation Commission has plans to put a pavilion and perhaps even a play area in Gallagher Creek to make it even more inviting to its neighbors.  But right now, if you bring your binoculars and your curiosity to Gallagher Creek as the summer wanes, nature, as always, will reward you with lots of beauty to explore.

THIS WEEK AT BEAR CREEK: Bear Creek Becomes a Park, 1969-2003

Last week, we explored nature in Bear Creek when it was a working farm 75 years ago. I thought it would be interesting to continue following its history to learn how it became our first publicly protected park. And the source for that information was  the “mover and shaker” who envisioned turning this abandoned farm into  Bear Creek Nature Park and  helped make it a reality – Parks and Recreation Commissioner Alice Tomboulian.

Many thanks to Alice and her husband Paul for sharing their knowledge of Bear Creek 45 years ago – and their photos below that I’m using with their permission! Also thanks to Parks Director Mindy Milos-Dale for great info and photos of the Grand Opening of the new park developments in 2003!

1969: Exploring an Abandoned Farm

Much had changed since the 1940’s when the Comps family lived on the farm. With no animals grazing, the grass in some Old Fields had grown tall, while rental farmers raised corn in others. The county had widened Snell Road, taking out the old sugar maples that once graced the front of the farmhouse. The county had also straightened Gunn Road, eliminating a steep curve that went around the far north of Bear Creek marsh by building a new straight crossing with a metal culvert. Sometime in the 60’s, the old farmhouse burned, leaving today only a remnant of an outdoor grill built by George Comps’ father  in the 1940’s or 50’s from stones on the property. (Hover over photos for captions. Click on photos to enlarge.)

When Alice and Paul Tomboulian and their family moved to Oakland Township in 1969, the land that became Bear Creek Nature Park was abandoned farmland still owned as an investment by Mr. Devereaux of the Richard C. Devereaux Foundation in Detroit (now of Bloomfield Hills). The Tomboulians were naturalists and lived across from this lovely piece of land.  Alice was a volunteer at Seven Ponds Nature Center in Dryden and  Paul headed the department of Chemistry and Environmental Health at Oakland University. They recognized the importance of those 107 acres – the marsh, the wetlands, the plants and wildlife – for conservation and preservation. In those days, children and their parents exploring empty land was common and not thought at all to be trespassing. So the Tomboulian family skated on the pond near Gunn Road and explored the woods and fields.

Early 1970s to 1977: Nature Study at Bear Creek

Alice and Paul Tomboulian and their three children used the land that would become Bear Creek as a perfect spot for nature study. Even Alice’s stepmother joined in! Exploring the marsh, for example,  took some gusto in those days before the docks were available for observation. So Alice and her stepmom waded in, fully dressed in old clothes, to explore the reeds for coot nests and other denizens of the marsh.  Along the way, of course, they also picked up the same kind of trash my husband and I retrieve in the park from time to time to this day!

One day Alice heard a chain saw roaring across the road and hurried over to see who was cutting down trees. It turned out to be the landowner, Mr. Devereaux. Rather than questioning her interest, Mr. Devereaux was pleased that someone was watching over  and protecting his land and gave his permission to explore and later, granted permission for Baldwin School field trips for nature study. Soon school children, their parents and teachers began arriving through a narrow path from Collins Road, which today is a much wider, developed path from the Township Hall. The children below and in the photo at the top of the blog, some sporting “Ranger Rick” neckerchiefs, would be in their fifties by now.

On that field trip on a sunny June day in 1969, the children did a bit of exploring around the pond, though of course no viewing from a deck was possible since none existed. Note the difference between 1969 and now. In 1969, the northern side of the Center Pond was edged only with tall grass – most of it non-native grazing grasses and native reeds. Now the north side of the pond is surrounded by  thickets of some native and many non-native invasive shrubs .

 

Here’s another group of Baldwin school children coming down the Eastern Path in June of 1969. Then a narrow foot path wound down through the eastern Old Field where the grass planted to feed the cows was starting to grow tall.

Now a wider, developed trail follows the same path but over the years, thanks to the stewardship of the  Parks and Recreation Commission, native Canada Goldenrod and other native  wildflowers have made a big comeback.  Black-eyed Susans, Coneflowers, Prairie Dock and Common Milkweed, beloved by Monarch butterflies, live peaceably beside non-native wildflowers like Queen Anne’s Lace and Ox-eye Daisies.

In 1974, an ecological survey of Oakland Township by Paul Thompson of the Cranbrook Institute of Science confirmed the importance of the land that is now Bear Creek. He briefly described the area that is now Bear Creek. as having “an excellent cattail marsh…several dozen muskrat lodges…an oak hickory woodland of moderate sized trees, and a number of small woodland ponds.”

1977 – 2003 Bear Creek Becomes a Park, Wild and Undeveloped

In the early 70’s, Alice and Paul Tomboulian and their children continued their nature study on the land that was to become Bear Creek Nature Park.  Mark, the Tomboulian’s younger son, was a born naturalist. Over the years that he explored Mr. Devereaux’s land,  he kept a list of every plant, animal and bird he saw.  Here Alice and her three children are doing some nature study at Bear Creek marsh in the 1970’s.  (Photo from an article in the Pontiac Press, now the Oakland Press.)

In the ’70s,  Alice was serving on the Oakland Township Board of Trustees. Armed with her own nature study and her son Mark’s wonderful list of the wildlife and plant life in the marsh, she proposed to the Parks Commission the creation of the township’s first park by buying Mr. Devereaux’s property.   And in 1977, The Oakland Township Parks Commission purchased the 107 acres of  land which is now Bear Creek Nature Park using $305,000 from the Parks Millage Fund.

At the time, township residents preferred keeping the parks with access only by footpaths. But problems needed to be solved in Bear Creek Marsh.   Over the years, the metal culvert under Gunn road installed in the 1940’s had  rusted and partially collapsed.  The drainage became blocked with runoff and debris from roadwork and development.  Water flooded the marsh, creating unnaturally high water levels,  “sometimes giving the appearance of a 8 acre lake,” as Paul Tomboulian puts it.  The high water was drowning a very special native habitat relied on by native wildlife. (Hover cursor over photo on right for caption.)

Alice, the PRC, and the Township worked with the Oakland County Road Commission for 16 years to correct this problem. According to Paul Tomboulian,  the old culvert eventually “was replaced with a new 78-foot long pipe in 2003, new water levels were set, and erosion control measures near Gunn Road were installed.”  Now,  the water level has returned to more normal levels and bulrushes, cattails and marsh wildlife are returning to Bear Creek Marsh.

September 2003 – Bear Creek Becomes a Fully Developed Nature Park

Later, when the Parks Commission became the Parks and  Recreation Commission, the PRC moved to make Bear Creek Nature Park even more accessible to the public.   With the approval of commission members,  Parks Director Mindy Milos-Dale sought out and wrote the Township’s first grant from the Michigan Natural Resources Trust Fund. The grant proposal was accepted and paid for 44% of the cost of facilities improvements at the park.  They included ADA accessible limestone trails, wooden boardwalks, docks and overlooks in wetland areas, a picnic pavilion, a children’s play area, a gravel parking lot and restroom facilities. The remaining cost was matched from Parks Millage Funds.

After all the careful planning and financing was done, Bear Creek Nature Park had its Grand Opening on September 27, 2003.  Visitors, like us today, enjoyed the Old Fields filled with the gorgeous orange and purple of fall’s Canada Goldenrod and New England Aster. They could hear Canada Geese and Sandhill Cranes crying overhead as they headed south. Visitors watched water birds from the observation deck as they do today. Muskrats and snapping turtles swam peacefully in Bear Creek Marsh.

 What a journey!  We owe a debt of gratitude to the vision, consistent effort and careful study of the Tomboulians, PRC commissioners over the years, Parks Director Milos-Dale and the support of many park-loving Trustees  whose foresight and careful planning protected the marshes, meadows and woodlands of Bear Creek for all of us who enjoy its very special beauties today.

THIS WEEK AT BEAR CREEK: Bird Antics, Goldenrod Duplexes and Squirrel “Dreys”

What a puzzling week, eh?  Was it spring or late winter?  The buds on the Silver Maple (Acer saccharinum) near the Center Pond seemed as confused as the rest of us.  They began to emerge as the sun warmed  the cold air.  I was concerned about the effect of icy nights later in the week.  Alas,  a twisted ankle meant I couldn’t get back to the pond to check on them. But maples seem to survive unpredictable Michigan winters, so we’ll hope it pauses and waits for a few weeks.  On a long walk one sunny, snowy day, I crossed the late night/early morning path of a rabbit  and went on to enjoy the antics of the “usual suspects” of a late winter day at Bear Creek: a Bluebird pair, a Chickadee pursued by a stalking Titmouse, and a Red-bellied Woodpecker busily poking at bark, looking for beetles. On a sunny, mud-slushy short walk with my somewhat tenuous ankle, I came across Goldenrod duplexes and while watching squirrels, decided I’d share some new info I read about these mischievous mammals.

Bird Antics from the “Usual Suspects”

Our Eastern Bluebird couple (Sialia sialis) seems to be sticking around despite fluctuating temperatures.  A hardy pair of Bluebirds!  This week I again spotted the female fluttering among the fruits of invasive Asian Bittersweet (Celastrus orbiculatus) – the vine that chokes our trees!

She will undoubtedly disperse the seeds in them in short order since birds have very quick metabolisms, if you know what I mean…

I wish she’d eat the Staghorn Sumac fruit(Rhus typhina) on the Western Slope! They’re native plants and are supposed to be on a Bluebird’s winter menu!

On the trail that leads north from the playground, a Tufted Titmouse (Baeolophus bicolor) stalked a Black-capped Chickadee  (Poecile atricapillus), apparently trying to see where it was caching its seeds in the tree bark. No matter where the Chickadee hopped or flew, the Titmouse was right behind.  Here’s the Titmouse with its crest raised.  It does that when excited, in this case perhaps perturbed by my camera,  or as this article suggests,  by trying to snitch some seed from the Chickadee’s hiding place!

The Chickadee looked pretty annoyed when it finally paused for a moment! Was it that annoying Titmouse or my camera?  Or was it  just its natural expression?  Who knows?

High in the trees, a Red-bellied Woodpecker (Melanerpes carolinus) made its wet “Kwirr” call as it hopped about a tree trunk, getting snow on its beak as it searched for bark beetles or other small creatures.

As I approached the top of the Western Slope that, a Blue Jay (Cyanocitta cristata) high in a distant tree spotted me and shouted its warning call, “Jay, jay, jay!!!!”,  announcing my presence to all the other birds.  Here’s one in an invasive  Autumn Olive bush (Elaeagnus umbellata) later that day.

The Blue Jay’s call often warns other birds about predators – or harmless humans like me!

Signs of Other Creatures: Tracks and the Duplexes

Rabbit tracks

Behind the Center Pond, my husband and I crossed the tracks of an Eastern Cottontail ((Sylvilagus floridanus) emerging from under a bush next to the trail.  Though you can see a rabbit almost any time of day, these tracks were likely made between dusk and dawn because rabbits generally feed at night.  In winter, their diet is mostly bark, buds and the twigs of woody plants.  Cottontails don’t usually live underground.  Though they use holes for raising young, the rest of the time, they huddle in piles of vines and brush. They will sometimes use a groundhog’s den temporarily during heavy snow – like this Wednesday’s snowstorm!

Along the path that runs just to the west of the Playground Pond, toward the benches at the top of the hill,  the Canada Goldenrod(Solidago canadensis) bulge with ball galls, the round, woody little dwellings that house the Goldenrod Gall Fly’s larva (Eurosta solidagnis) for the winter. (See the blog from January 21 for more info.)   Lots of them will successfully hatch out in the spring, but it looks like this one won’t.  Instead it probably provided much-needed protein on a cold day – perhaps for a persistent Chickadee who had to chip away for a while to get to the larva inside.

Chewed goldenrod gall
I wonder if this work on a Golderod Gall was done by a very persistent Chickadee trying to get at the larva inside.

Nearby, I found a whole patch of Gall Fly duplexes!  The holes in these galls are the neat little ones usually made by a Downy Woodpecker (Picoides pubescens).  They are experts at drilling holes to find food, after all.  Goldenrod Gall Flies must be a great source of sustenance for birds in the winter!

Squirrels in the Winter

This month the Seven Ponds Nature Center in Dryden had an informative newsletter piece about squirrels, written by Lois Rheaume, a naturalist on staff there. Having read it, I decided that I needed to read more about them.  Bear Creek, of course, is full of squirrels, three different species that seem like four!

From top to bottom below:  the American Red Squirrel (Tamiasciurus hudsonicus), the Fox Squirrel (Sciurus niger),  and the Gray Squirrel (Sciurus carolinensis) which comes in two basic colors, gray or black – and variations of those.  (No, they are not a cross with a Fox Squirrel; that’s genetically impossible.)

According to Ms. Rheaume, Fox and Red Squirrels were most common in our area when the land was heavily farmed.   Red Squirrels and Fox Squirrels spend more time on the ground so open farm lands suit them. Gray Squirrels spend more time up in trees, so as trees have taken over open fields and have matured in suburban neighborhoods, more Gray Squirrels have moved in.   Squirrels can move easily up and down trees because their back feet can rotate 180°!

Fox and Gray Squirrels bury nuts underground.  Using excellent spatial memory and a keen sense of smell, they find about 95% of them.  (The forgotten ones help trees to sprout in our forests.) The Red Squirrel, who grows a rusty strip of fur down its spine for the winter, makes a cache on top of the ground.

Ms. Rheaume’s piece informed me that squirrels assess acorns by rotating them quickly under their sensitive noses with their front paws. They tend to eat White Oak acorns (Quercus alba) right away because they have thinner shells and sprout more quickly.  They’re also less nutritious for them.   Squirrels are more likely to store Red Oak acorns (Quercus rubra)  which contain higher amounts of tannin to preserve them and because they contain more fat and nutrition for winter months.  Amazing what creatures know.

Some folks may not know that squirrels build nests in trees, nests that can be mistaken for those of hawks, for instance.  Squirrels prefer a tree hole on a cold, snowy night but they are frequently unavailable.  They build nests, called “dreys” in the fork of a tree or where a sturdy limb meets the trunk.  These dreys can be used for young in the summer but they can also come in handy on cold days.

Squirrel nest1
Squirrel nests, called dreys, appear more in the fall when the leaves have fallen.

Dreys end up being a foot or more in diameter and start out with a platform of small branches with green leaves attached.   Squirrels gnaw off these branches before autumn, so that the leaves don’t fall, but stay on for the winter.  Ms. Rheaume saw one dislodged by a storm.  It contained “a fluffy layer of leaves and sticks on the outside with the next ‘wall’ lined with several layers of oak leaves, making a virtual waterproof barrier for the soft grasses, shredded bark, and lichens which make up the soft bed in the center.”  According to Wikipedia, dreys have one or two “entrance/exit holes…usually close to the bottom and oriented toward the trunk which keeps the rain out.”  Sounds reasonably cozy on a cold night, doesn’t it?

Fallen queen annes (1)

It seems that the coming week will be as topsy-turvy as the last one – a huge snowstorm followed by a warm weekend.  The dry stalks of last year’s plants, like the Queen Anne’s Lace (Daucus carota) above, are succumbing to the weight of snow, wind and cold.  But through it all, the creatures of Bear Creek find ways to keep warm, find food and keep us company as the days get noticeably longer. I heard a report of a Sandhill Crane (Grus canadensis) arriving this week.  We have lots of Red-winged Blackbirds (Agelaius phoeniceus) in our yard  and we saw an obese Raccoon (Procyon lotor) taking a hibernation break and stuffing itself beneath our bird feeder.   Perhaps these springtime creatures were fooled by  strangely warm winter days or perhaps they know something else we don’t!  Time will tell.

THIS WEEK AT BEAR CREEK: From the Sedate Colors of Late Autumn to Winter White

Cam in red winter coat BC
Blog post and photos by Cam Mannino

I’ll be the first to admit that wildlife was a bit quiet this week at Bear Creek Nature Park. The early part of the week was typical of November – brown and gray.  So I went searching for bright colors or interesting shapes and found a few native plants, lichens and mushrooms adding  what designers call “visual interest” to the landscape.  And then suddenly at the end of the week, winter arrived!  I’m enough of a child to still love the first snow – and what a snowfall! Early Saturday morning, I walked through a silent Bear Creek – even my footsteps were muffled by the snow. Walking over an hour across the fields and through the woods,  I heard the twitter of one Tree Sparrow and a Chickadee’s call, a Blue Jay warning the world of my presence,  the soft “chip” of one Northern Cardinal and the inevitable low grumble of an American Red Squirrel annoyed by my passing – but I saw none of them as they huddled away from the swiftly falling snow.  So this time our weekly virtual stroll through Bear Creek travels quickly from late autumn to early winter.

Late Autumn:  A Search for Colors and Shapes

Falling bur oak leaf

Late November is a tough season to love.  The vivid colors of October drain away as the sap flows down into the tree roots and the landscape turns gray and brown.  Birds are more scarce and harder to see as they twitter softly inside bushes or high in the trees. Bird nests appear in the bare branches – like this shrunken sack over the Playground Pond, the remains of the nest of a pair of Baltimore Orioles (Icterus galbula).  This spring I saw the yellow/orange female’s tail protruding from the top as she fed her young in the nest below. Her brilliant orange and black mate helped out, making frequent trips to the nest.  Look at that lively little home now!

So I decided I’d keep my eye out for any color or interesting shapes that I could spot in the park.  Unfortunately, a lot of the color comes from invasive plants!  After all,  one of the reasons they escaped from people’s gardens is that they provided color late in the year.  But I wanted to see what our native plants could provide.

The Staghorn Sumac (Rhus typhina) still had bright scarlet plumes on the western slope.

And everywhere the red leaves of Common Blackberry (Rubus allegheniensis) broke the tawny sameness of late autumn.

Common Blackberry adds a smattering of red to the brown landscape of late autumn.

All over the park, small trees bravely waved their large leaves which they’d used to soak up as much summer sunshine as possible.  This tiny Black Oak (Quercus velutina) may someday be a huge, spreading tree since it found a place in full sun on the western slope.  Its crimson leaves stood out in the field of dried Canada Goldenrod (Solidago canadensis) and Queen Anne’s Lace (Daucus carota).

Tiny black oak tree

A ball gall on what appeared to be another blackberry bush took on the dark reddish sheen of its host.  Galls occur when insects lay their eggs in plant stems and the plant grows around it,  providing a relatively safe place for the insect that will emerge in the spring.

Reddish gall
A ball gall on what I think is a blackberry bush houses the larva of at least one insect, possibly more, until spring.

Near one of the wetlands, the bright red and green of a moss-covered log caught my eye.  Dr. Ben VanderWeide, Oakland Township’s Stewardship Manager,  tells me, “Mosses are really cool … The green part that we always see and call “moss” is actually the “gametophyte generation” of mosses  –  the generation with one copy of DNA that produces “gametes,” sperm and egg. When it rains, the sperm swim through the film of water on the mosses to reach an egg in the tip of one of the green mosses. After fertilization of the egg, a new plant grows into the “sporophyte generation” (red filaments in the picture below), which has two copies of DNA and produces spores. The spores then spread about and germinate to grow into new carpets of green moss.”

Moss on a log green and red
Moss on a log. The green generation of moss produces next generation – the red filaments, that produce the spores which grow into more green moss.

Dr. Ben continues. “So what you see in this patch of moss is actually two generations – the green moss carpet that one has one copy of DNA, and the red filaments are the sporophyte offspring that have two copies of DNA. ”  I think that’s pretty cool, too. I’ve come to appreciate these bright red and green patches of moss in the austere seasons of the year, early spring and late fall.

Near the Marsh and in the Woods,  Some “Visual Interest”

When I entered the woods, color was even harder to find.  A rich brown acorn with its green top and rotund shape provided some visual relief among the wrinkling surfaces of fading fallen leaves.

Acorn
The rich chestnut brown of an acorn adds a bit of visual interest to fading brown leaves on the trail.

Though pale in color, I like the filigree of lichens and fungi that become more evident as the colorful flowers fade.  Lichens are sometimes confused with moss, but they are not related. In fact, lichens aren’t plants; they are a distinct form of life!  According to Wikipedia, they are composite organisms that arise when algae and/or cyanobacteria live symbiotically among fungi filaments. They don’t have roots like plants do.  Like plants, however, they produce the algae or cyanobacteria partner that produces food for the lichen through photosynthesis using sunlight, water and minerals.  Lichens may appear on plants, wood or rock, but they are not parasitic.  Pretty mysterious life form, really!  Here’s a lacy-looking one that is referred to as “foliose” because its structure looks like leaves. It’s on a railing at the southern marsh deck. And that yellow you see behind it is another lichen, a powdery one whose structure is referred to as a “leprose lichen.”

Lichen
A lichen does not have roots and is not a plant,but rather is a special composite life form that, like plants, is capable of photosynthesis. Both the white one in the foreground and the yellow spots in the background are types of lichen.

“Mushrooms,” are the fruiting bodies of  fungi that emerge from wood or soil and carry the spores for reproduction.  Fungi  form a distinct “kingdom” in nature, not related to plants, animals, bacteria, etc. I saw two forms of one broad category on this walk, the “polypores.”    Here are some polypore fungi on a snag  (standing dead tree) near the southern marsh. According to Wikipedia,  “Through decomposing tree trunks, they [fungi] recycle a major part of nutrients in forests.” They are the first step in a food chain: fungi process the wood cellulose, insects and invertebrates eat the mushrooms and birds and larger animals eat the insects and birds.  Fungi also soften up dead wood so that woodpeckers and others can make holes for nesting or winter shelter.  Nothing is wasted in a well-functioning ecosytem, eh?

I’m always intrigued by how Shelf Fungi, another kind of polypore, form ruffles on the edges of sawed logs.

So the early part of the week at Bear Creek was still brown leaves underfoot, graying blooms of summer plants dropping their spring seeds in the Old Fields and pale mushrooms and lichen taking shape on old wood throughout the Oak-Hickory forest.

And Then Suddenly, Winter!

On Saturday morning, the snow began falling fast, like rain, cloaking Bear Creek’s Eastern Old Field in white.

The plumes of Canada Goldenrod began to droop a bit under the weight of the snow.

A few red bright red leaves wore a bright cap of snow near the marsh at the southern of the eastern Oak-Hickory forest.  The Common Blackberry from earlier in the week now has snowy accents.

The woods were, as poet Robert Frost put it,  “lovely, dark and deep.” And so quiet.  Not even a squirrel moved. Only an occasional muffled bird call reached me.

To borrow again from Frost, perhaps you too can bundle up and experience “stopping by woods on a snowy” morning during the hectic holiday season that begins this week. Caught up in the glitter and bustle of a busy season, the woods and fields offer serenity, quiet, beauty – a soothing space in which to breathe and find your bearings.  Have a wonderful Thanksgiving!

THIS WEEK AT BEAR CREEK: Departing Guests, the Winter Crew and Trees Storing Energy for Winter

 

Across the eastern old field from pond path

Hard frost and driving winds  – November asserts its presence at Bear Creek.  Geese and ducks are re-thinking their presence in the ponds and marshes and gathering to move south.  Most migrants have moved on.

But the winter bird crew calls to its fellow foragers as they all stock up for the coming snow.  Plant pods crack open, dropping seed or sending them flying through the air with the last of the leaves. Trees have almost finished storing energy in their roots.  Like us, Bear Creek’s almost ready to face another winter.

Departing Guests

Large flock of geese
Hundreds of Canada Geese gathered over the marsh at dusk, heading south.

At dusk one night this week, I heard (before I saw) the cacophony of hundreds of Canada Geese (Branta canadensis) as they gathered over the marsh to begin their migration.  The sound of that many wings at once and their wild calls felt like the very essence of late fall.  I wish I could have captured the sound of those geese but I literally was transfixed by the sheer volume, the roar, of their noise.

In the hour before, I’d seen and heard smaller groups of geese wheeling overhead near the treetops, heading southeast to join this larger flock.

Geese at dusk

Mallards (Anas platyrhynchos) are still in the ponds.  This shot from last fall shows a male after his molt, with a whole set of perfect new feathers, ready to find a mate and take off for the south.  A new set of feathers makes flying that much easier for migrating birds.

Mallards are beginning to gather in larger flocks as well, readying themselves to move off  when ice forms on the ponds and in the marsh.

The Hardy Birds of the Winter Crew

Birdsong is long gone now,  but the winter birds use chips and calls to keep in touch with larger flocks as they busily forage. American Tree Sparrows (Spizella arborea) probe for fruit and seeds from bushes on the western slope. (Click on double photos to enlarge. Rest your cursor on a double photo for captions)

Here’s a link if you’d like to hear the musical tweet these travelers use to keep in contact.  (Page down to “Calls” and click on the first one.)

Dark-eyed Junco (Junco hyemalis), a bird that is usually a ground feeder, pulled industriously at a cluster of goldenrod to get at seeds which had not yet fallen.

A pair of Northern Cardinals (Cardinalis cardinalis), who always brighten dark days, looked at me warily from small shrubs near the wetland below the south hill.  According Nature in Winter by Donald Stokes, these adult cardinals live no more than “a few miles from their place of birth.” So  these Cardinals, which can live for many years, could have  resided in Bear Creek for a long time.  Cardinals pair up for the winter and 80% of them stay with their mates the following year.

Here’s a  Downy Woodpecker (Picoides pubescens) who’d just finished vigorously attacking a seed and was apparently tipping its head up to swallow the results.

The female Downy Woodpecker has no red spot on the back of her head, as the male does.

The photo above came from our back yard this week because the ones I saw in the park seemed to never stay in one spot for more than a split second.  But I like the look of this one’s wings as it took off from a branch in the park!

I saw House Finches (Haemorhous mexicanus ) in Bear Creek this week but, like the Downy, they were too quick for me.  So instead I took these pictures of a male and female at our home, where the feeder keeps them nearby.  According to Cornell Ornithology Lab, House Finches were originally western birds.  ” In 1940 a small number of finches were turned loose on Long Island, New York, after failed attempts to sell them as cage birds (‘Hollywood finches’). ”   In the next 50 years, they spread all over the eastern US and southern Canada. I can’t imagine these social birds in cages!!

Winter Crew Animals

Below all those migrating birds in the marsh, a new muskrat lodge is being constructed. Since Muskrats (Ondatra zibethicus) are most active at night, dawn or dusk,this lodge was probably constructed in semi- or complete darkness!  This one maybe become a full-fledged winter dwelling, as large as the one in the Center Pond,  or it may just be a smaller feeding platform, a place to come up through the ice during the winter to breathe and eat.

Three White-Tailed Deer does (Odocoileus virginianus) that had bedded down near the Center Pond moved slowly behind a scrim of trees near the wetland below the southern hill.  Maybe they were headed to the western woods to eat some of the plentiful acorns, but this one stopped to peek around a tree at me.

And over in the western woods, an agitated Fox Squirrel (Sciurus niger) stopped dead when it spotted me, but flicked its tail at top speed, its version of a threat gesture.

Squirrel with moving tail
An agitated Fox Squirrel, its body completely still, was waving its tail so fast that it blurred in the photo.

Seeds Everywere

Hard frost may have brought the demise of many insects in the park, but seed-eaters can choose from a gigantic larder!  Perhaps you remember the Wild Senna (Senna hebcarpa) growing in the native beds near the shed.   They’ve now produced long pods which turn black when the seeds inside are mature.  Native bumblebees seek the pollen while ants and ladybugs, that may protect the plant from predators, love the nectar.  The caterpillars of Sulphur butterflies (the family of small yellow ones) feed on its foliage.  The seeds in those long black pods appeal to Northern Bobwhites (Colinus virginianus), a small quail with a distinctive whistle once plentiful in Oakland Township,  but now largely missing.  As native plants like Wild Senna, that serve so many creatures, return to our parks through careful stewardship, we hope to see the return of birds like the Bobwhite.

Mixed in with the ubiquitous Canada Goldenrod (Solidago canadensis) last summer was the more delicate native, Grass-leaved Goldenrod (Euthamia graminifolia), which looks quite lovely as it seeds. Native bumblebees, honey bees, butterflies and lots of other insects enjoyed its nectar during the summer and American Goldfinches (Spinus tristis) feed on it now.  Occasionally it feeds rabbits and deer as well – another important plant in the park’s native habitat.

The modest Thimbleweed (Anemone virginiana) , a favorite of small bees and hoverflies (that look like bees), is seeding into airy puffs right now.

Trees Conserving Energy for Spring

All summer, the leaves of the Park’s deciduous trees produced sugars by storing the energy of sunlight in chemical bonds  (photosynthesis). By autumn, this energy in sugars is safely stored in the roots of the trees, away from the snow and cold.  During summer and fall, trees also produce next year’s leaf buds, and in some cases, flower buds, for next spring.  The buds are packed with miniature leaves which are covered with a waxy coating that protects them from the cold.  In the spring warmer temperatures and longer days break the ends of the cold waiting period, signaling sugar-rich sap to rise. The leaves, fed by the sap, burst forth and start again to supply the tree through photosynthesis. Pretty nice arrangement, I’d say!  Here are some leaf buds on Maples in Bear Creek.

Perhaps we can make peace with the changing season by knowing that the seeds of spring wildflowers are already planted and the leaves of favorite trees wait inside those leaf buds for a warm spring day.  Some of us go south like the migrating birds.  Others of us are like the trees who husband energy in their roots, but stand tall when snow covers their branches. We too turn our energies more inward in the winter, perhaps by a warm fire, but still sally forth, sporting cherry noses and pink cheeks , to enjoy the wintry world.   Bear Creek welcomes you in any season.

THIS WEEK AT BEAR CREEK: Golden Fields Full of Monarchs, a Hummer and Other Beauties and Curiosities

Open fields edged by trees have always been favorite places of mine.  And this Tuesday,in the fields on either side of the park, Monarch butterflies were everywhere!  Bear Creek may be hosting fall migrators on their way to Mexico – or we’ve just had a big hatch of  these beautiful and ecologically fragile creatures.  In fact, many butterflies, bees and darners fluttered, hummed and hovered over the swaying seas of gold in Bear Creek, while grasshoppers serenaded them beneath the tall stems.

Some speculate that humans love open fields because our ancient ancestors felt safe where they could see into the distance but escape into the trees.  I just know I’m very happy in a field full of wildflowers.

First, of course: The Monarchs and the Hummer!

After only seeing the occasional Monarch Butterfly (Danaus plexippus) this summer, on Tuesday they were floating and fluttering all over the park!  Though the Joe Pye (Eutrochium maculatum) in the Eastern Old field seems to be past its peak,  its nectar drew in a Monarch (and other butterflies below) anyway.

I considered myself lucky to get so close – but when I started down the Western Sloping Path from north to south, wow!  Monarchs surrounded me every step of the way.  I believe I saw at least a dozen there, but I’ll share just a few who were enjoying the New England Asters.

At the very bottom of the sloping path, I watched as two Monarchs approached and fed on the same plant.

Just at that special moment, I saw the second Ruby-Throated Hummingbird (Archilochus colubris) I’ve ever seen at Bear Creek – a female, hovering momentarily as she looked at me and then zoomed off toward the woods.  No photo, of course, but perhaps this silhouette of a hummer in mid-hover from a few years ago will help you visualize the one I saw this week.

Fields Full of Wildflowers and their Beautiful Visitors

Eastern Tiger Swallowtails (Papilio glaucus) fluttered quickly across the golden fields.  I just caught sight of one in the far distance on the Eastern Path on Sunday so here’s a picture from another  August, when a male landed on Spotted Knapweed, an invasive wildflower.

New England Asters (Symphyotrichum novae-angliae) increasingly complement the Goldenrods’ glow as these vivid native flowers grow tall to reach their share of the thinning sunlight.

Great Spangled Fritillary in the Eastern field paused on fading blossoms of Joe Pye to take a sip, just like the Monarch did.

And the Silver-spotted Skipper (Epargyreus clarus) rested beneath a blossom of the same plant.

About That Hum in the Old Fields…

Honey Bees (Apis mellifera), native Bumblebees (genus Bombus) and even Eastern Yellow Jacket Wasps (Vespula maculifrons ) hum among the flowers in the Old Fields.  Don’t worry; they’re much too busy gathering pollen, or in the case of wasps, eating nectar, to bother with us humans.

Bee on goldenrod2

Always on the lookout for a quick munch, the big Canada Darner Dragonfly (Aeshna canadensis) zooms and dives over the blossoms below. This B-52 of insects consumes a lot of late summer bugs.

Below the Darner, a modest wet-footed flower stands among the wetland reeds in the Eastern Old Field. According to Wikipedia, Boneset (Eupatorium perfoliatum) got its name because our ancestors believed that since the leaves clasped the stem “wrapping the leaves in bandages around splints would help mend broken bones.”

Reportedly Boneset got its name from a past belief that because the leaves clasp the stem, it would help with mending broken bones.

Down in the grass, the Red-legged Grasshoppers (Melanoplus femurrubrum) sing lustily as a backdrop to all this beauty by rubbing their rasp-like back leg against their forewing.

Yellow Jackets, like all wasps,  don’t do much pollinating because they lack the fuzzy body hair of bees.  They generally eat nectar but collect bugs for the protein they feed to their young.

What’s That Bump on the Goldenrod, Anyway?

As you’re wandering through the Old Fields, you may have noticed some strange shapes on the stalks and tips of Canada Goldenrod (Solidago canadensis).   Galls are growths on plant stems caused by insects who lay their eggs on the plants in the spring.  When the larva hatch, they eat into the plant, causing it to form a gall around them.  Inside, the larva eats until late summer when it forms a pupa which spends the winter inside that protective covering.  In spring, the adult insect emerges to restart the life cycle. Galls don’t kill the Goldenrod; they just look funny!

The ball gall is the most common goldenrod gall and is formed by  the small Goldenrod Gall Fly (Eurosta solidaginis).  With its hard surface, this gall seems like a decent place to spend the winter, doesn’t it?  During the summer, though, some wasps lay eggs in galls and their larvae hatch and make a meal of the gall fly’s.   And in the winter,  Downy Woodpeckers drill holes in galls to reach the pupae,  and Gray Squirrels chew on galls to do the same.  Obviously enough Gall Flies survive in these dwellings to start a new crop next spring, so nature stays in balance. I think this gall may have been invaded by a wasp.

Goldenrod gall2
A ball Goldenrod gall formed by the larva of a Goldenrod Gall Fly who turns into a pupa and spends the winter there – though the holes indicate that perhaps a wasp has invaded this gall and its larva may have eaten the gall fly’s.

Goldenrods also harbor the very tiny (.2″) Goldenrod Gall Midge (Rhopalomyia solidaginis) which causes a rosette gall.  Once the grub of this tiny creature hatches, the stem of the goldenrod generally stops growing but keeps producing leaves which bunch up and make a nice hiding place for a midge’s larva to grow – along with spiders and other midges who may move in.   Sometimes, as in this photo, the stem will continue to grow above the rosette gall, but it’s much more spindly.

Goldenrod gall_edited-1
A rosette gall on Canada Goldenrod created by a single tiny insect but potentially a hiding place for other midges and spiders as well.

For years I saw willows in the park that seemed to be producing pine cones at the end of their branches.  Turns out they’re Willow Pine Cone Galls, made by a tiny (about .2″) midge scientifically known as Rhabdophaga strobiloides.  The pine cone-shaped gall that its larva causes can harbor many species.  According to the University of Wisconscin-Milwaukee’s Field Station website, “Beetles, caterpillars, sawflies, cynipid wasps, midges, and the eggs of meadow grasshoppers have been found inside pine cone galls.”  They’re now on a willow on the west side of the Center Pond and can also be seen in the wetland area east of the Eastern Path.

gall
No, not a pinecone! A Willow Pine Cone gall that can harbor over 30 different species besides the larva of its original midge.

The Eastern Old Field rolls down to the Center Pond and the Western one slopes dramatically to the west.  The trails that wind across them are full of strange and beautiful creatures and the plants that feed on and live in them.  Walk quietly. Look closely.  Listen carefully.  And when nature shares a secret with you, please share it with the rest of us.

THIS WEEK AT BEAR CREEK: Changes! Birds Molting, Plants “Fruiting,” Caterpillars Creeping and Humans Making Improvements

Last week I took a side trip to Draper Lake with all its lavender flowers, fish and insects! Hope you saw the previous post. So now let’s get back to Bear Creek!

Have you noticed that a hush has fallen over the park?  Oh, you’ll hear the American Goldfinches who are raising young now, the Cardinal’s trill, the chipping of a sparrow, the harsh cry of a crow or maybe a flock of crows.  But many birds are beginning to molt, replacing their feathers for migration, singing less as they freshen up for autumn.  The eggs of butterflies and moths have hatched into caterpillars who are inching along host plant stems. Plants of all kinds are turning from flowering to “fruiting.”   And what are those human work crews doing at the park?  Summer begins to wane and change is still the norm at Bear Creek!

Freshening Up for Fall:  The Molt

According to the Cornell Ornithology Lab, birds’ feathers are like our hair or fingernails – hard structures that can’t repair themselves if they’re damaged. So birds periodically molt, which simply means they replace worn, damaged feathers with fresh ones.  Since this uses a lot of energy, most birds have a complete molt in late summer after they’ve finished raising their young and for migrating birds, before the fall migration .   Some birds – like warblers, tanagers and buntings –  do one full molt and then have a partial molt to change into their courting colors before breeding season. Others molt more often or only molt wing feathers.  So it’s a highly variable process.

Canada Geese (Branta canadensis) are big birds  with long feathers so molting takes time!  They remain in the reeds with their young in July and spend 30-45 days replacing their feathers before migrating.  They can be unusually quiet during this period because they are vulnerable; neither they nor their young can fly until the molt is over.  They must swim or walk to find food.  This photo, taken earlier in the summer and not at Bear Creek, shows an adult and young before their molt.

Canada Goose w young

Others birds, especially smaller ones,  continue to be active during their molt. This Indigo Bunting (Passerina cyanea)  wasn’t hiding or quiet; he was singing at the top of a tree this week.  But  you can tell his head feathers aren’t the beautiful blue they were earlier in the summer and look a bit thin like a balding human male.  Male Indigo Buntings do a complete molt in August,  and then a partial molt in the spring to cover themselves with bright blue feathers and black wings for courting the females. To see all the stages of an Indigo Bunting’s molt, visit the Cornell Lab link above.

The chatty Gray Catbird (Dumetella carolinensis) tries to warn away intruders, like you and I, during the molt with the famous “miaow” call from which they get their name.  That call is everywhere in the park right now!  Here’s the sleek gray catbird before molting:

catbird2
The secretive Gray Catbird goes deep in the bushes before its molt but it “miaows” if any intruder approaches, including those of us walking in the park!

And their “miaow” alarm call sounded like this on the west side of the northern loop trail last week.  I must have been quite close to the Catbird because it was a very insistent call! (Remember to turn up your volume!)

When nesting is over, Tree Swallows (Tachycineta bicolor) become very social and gather into flocks to molt and migrate .  This week a small group of them were swooping above the grass near the playground and chattering together, before landing in a dead tree near the Playground Pond.  Their migrating flocks can number in the hundreds of thousands!

Tree Swallows

Field Sparrows (Spizella pusilla ) are always hard  for me to photograph.  I see them from a distance as they skulk in tall grass or low shrubs always moving out of sight just ahead of me as I walk.  So I was glad to get these two shots.  I’m not positive, but I think the first is a juvenile since it has the light streaks on its upper breast of a fledgling but the white eye ring and pink feet of an adult Field Sparrow.

Fledgling Field Sparrow
What appears to be a fledgling Field Sparrow hides among the greenery of a small bush, in true Field Sparrow fashion.

A few days later, though, I saw this sparrow on the walnut lane at the center of the park, and from the condition of its feathers,  I think it may be a molting adult Field Sparrow.  Please, all birders feel free to set me straight, of course!

What appears to be a molting adult Field Sparrow – white eye ring, pink bill and general strangeness in the feathers!

Flowers Bear Fruit…but not the edible kind.

After plants are pollinated and fertilized, they develop “fruit,” that is,  structures in or on which seeds mature and which disseminate that seed.  Fruits can fly through the air like maple seeds in their winged packages or cling like burrs for traveling or get carried away and eaten, like a ripe berry.  Some of the plants introduced in earlier blog posts are now “fruiting.” For example, remember Wild Senna (Senna hebecarpa) in the native bed by the shed? It’s flowering in the photo above and look at the “fruits” it’s formed now,  the long pods in the second photo.

Wild senna Senna herbecarpa

Fruit wild senna
The fruit, long seed pods, of Wild Senna in the native bed near the shed.

Delicate Enchanter’s Nightshade (Circaea canadensis)takes a different approach.  Its fruit has stiff hairs, like a burr, that can attach to animals’ fur or clothing.  The branches of these sorts of plants often bend downward in late summer, assisting in the process of reaching a passing fox, dog, whatever.  Below, the flowering plant and then its fruit:

enchanter's nightshade

Enchanter's NIghshade fruits
Enchanter’s Nightshade uses small burr- like fruits to transport its seed – fruits being explored here by a small spider.

And the familiar Common Milkweed (Asclepias syriaca) uses the airborne seed as we all know.  Right now the meaty, dusty-pink flowers are withering and the fertilized ones are developing  milkweed pods, the fruit within which its seeds are maturing.  When ready to go,  the dried pods will crack open and the airy silk, called comaattached to each seed will take them sailing with the wind across the Old Fields.

Milkweed pods
The seeds inside the pods, or fruit, of the Common Milkweed are still maturing. When they’re ready, the pods will dry, open and the seeds will sail away on the airy silk attached to each seed.

Caterpillars Emerge to Munch!

Speaking of milkweeds, I’ve been trying to find a Monarch caterpillar (Danaus plexippusmunching on one for weeks to no avail!  Parks Commissioner Colleen Barkham tells me she has three in her garden!  I’m clearly just not being lucky enough to see this amazing stage of the Monarch’s life.  But here’s Ben’s photo taken last year along the Paint Creek Trail.  Pretty jazzy, eh?  That color, like the Monarch butterfly’s, tells predators that the milkweed has made it toxic.  Let me know in comments if and where you see one!  Please!

This monarch caterpillar is feeding on the orange-flowered butterfly milkweed. As the larva feeds on the milkweed, it gets toxic chemicals that it uses to protect itself from most predators.

The Milkweed Tussock Moth’s (Euchaetes egle) caterpillar wards off predators with soft spikes and the same yellow, black and white coloring as the Monarch caterpillar.  The moth, however, is a dull gray unlike the vivid colors of the beautiful Monarch.

MIlkweed tussock Moth caterpillar
The Milkweed Tussock Moth caterpillar is similar in color to the Monarch’s and both feed on milkweed, making them unpalatable to birds and bats.

East of the walnut lane, less appealing caterpillars,  Eastern Tent Caterpillars (Malacosoma americanum), have made their silk web in a tree which they will partially defoliate as they feed. The tents are pretty amazing, though.  According to Wikipedia, “the tent consists of discrete layers of silk separated by gaps and the temperature in these compartments varies markedly. Caterpillars can adjust their body temperatures by moving from one compartment to another.”  They gather in a sunny compartment on a cool morning as in the photo below,  but move into  shadier ones to escape hot afternoon sun.

And what about those human changes?

Bear Creek Nature Park is benefiting from two great projects. The Parks Commission’s maintenance crew repaired and upgraded a bridge on the southern edge of the Oak-Hickory forest in the northwest park of the park.  Now we have a beautiful, sturdy new bridge over the wetland area with a ramp to take you safely down the north side.  Thank you maintenance crew (Doug Caruso, Jeff Johnson, Clif Selent, and Lou Danek)!

Near Snell, Oakland Township Stewardship Manager, Ben VanderWeide, and his summer technicians spent a couple of hot, dirty but productive afternoons clearing a large area east of the pavilion near the Snell parking lot.

Stewardship clearing
A 60′ x 60′ area cleared by the Oakland Township Stewardship crew for a new native plant bed.

A generous citizen,  Nancy Parmenter,  has donated all the native plants she cultivated in her carefully tended garden for 20 years since she is moving and the new owners didn’t want them!  In the fall, Ben and others (the technicians will be back at college) will dig up over 30 different native species and transplant them into this newly cleared area.  What a treat to have a free, HUGE number of native plants for a new Bear Creek bed. Thanks crew and Nancy Parmenter! If you want to help with the transplanting effort,  just let us know!

Coming Attractions:  Here Comes the Goldenrod!

Right now, areas of the park are draped in the white of Queen Anne’s Lace.

But shortly, the park will blaze with gold.  Goldenrod will take over the Old Fields.  The most prominent variety in the park, Canada Goldenrod (Solidago canadensis) is on the right in the photo below.  But it’s accompanied by other varieties as well, like  Grass-leaved Goldenrod (Euthamia graminifolia)  on the left.

Two kinds of Goldenrod at Bear Creek now – Grass-leaved Goldenrod on the left, Canada Goldenrod on the right.

By the way, Goldenrod, despite its “bad rep,” is probably not the cause of anyone’s fall allergies. Goldenrod’s heavy pollen can’t travel far on the wind.  The culprit is more likely Common Ragweed  (Ambrosia artemisiifolia) which blooms at the same time and whose pollen can be carried 40 miles on the wind!  Here’s a link to a photo of Ragweed.

Goldenrod spreads through rhizomes, underground stems that produce roots and shoots. In fact,  this native plant has become an invasive species in Germany and China !  How’s that for a reversal?  But here it provides lots of late summer pollen for bees and other pollinators and a golden glow as summer turns to fall!  Coming soon to an Old Field near you!

So in the hot, dog days of summer, Bear Creek keeps changing, making room for freshened-up birds, butterfly metamorphosis, seeds for next year’s flowers and a new native bed.  A reminder to us humans that change is inherent in nature as well as in our lives – and that’s a good thing!
