Stony Creek Ravine Nature Park: Busy, Sunlit Meadows and Moist, Mysterious Shade

The west branch of Stony Creek runs through a steep ravine visible. You can see the creek from the trail that runs along a ridge high above the creek.

If you’d like a short, quiet walk all alone (I do occasionally), consider wandering for an hour or so in Stony Creek Ravine Nature Park. This 60 acre park is a bit  farther off the beaten path than our other township parks; I seldom see another hiker when I’m there. For now, it’s only accessible from a single parking space at the end of Knob Creek Trail which is off of East Buell Road. It’s an in-and-out trail (no loop) that begins in sloping, glacial meadows. Follow the trail into an oak forest overlooking a deep ravine in which Stony Creek burbles and flows around fallen trees and rocks far below. The Parks Commission has been awarded a matching grant from the Michigan Natural Resources Trust Fund to join this little park to 208 spectacular acres along Snell Road. But for now, it’s a quiet little getaway.

Exiting a small woods at the start, the trail winds up through sunny meadows to the dark oak forest.

Sunny Meadows:  Illusive Birds and a Big, Beautiful Butterfly!

The meadows along the first part of the trail are alive with morning birdsong – but seeing the birds is a bit tricky, especially in July. Many adults are hidden high in leafy branches and the recently fledged young huddle deep in the lower greenery, staying out of sight as they wait to be fed. My first sighting was a small flock of tiny brown birds moving quickly back and forth between a leafy bush and a small, dense tree. Suddenly I became aware that my camera and I were being scolded by an annoyed adult House Wren (Troglodytes aedon) perched behind me. (For a perfect replication of its chatter, listen to the second “Calls Northern” recording at this Cornell Lab link.)

An adult wren scolds its young into hiding and scolds me as well!

No doubt its chatter also served as a warning to the fledglings to hide. But eventually a curious fledgling popped into the open and had a look around. It looked like a plush toy with tiny wings! (Click on photos to enlarge; hover cursor for captions.)

Far out in the meadow in a tall, bare tree against a gray sky, the Eastern Towhee (Pipilo erythrophthalmus) threw back his head and sang. He abbreviated his spring song from “Drink your Teeeeeea” to simply “Your Teeeeea.” Just a reminder to other towhees, I imagine, that he was on his territory.

An Eastern Towhee belts out his song high in a bare tree above the meadow.

Wherever Bee-balm (Monarda fistulosa) and Butterfly Milkweed (Asclepias tuberosa) grace a meadow, it seems the butterflies gather to sip their nectar.

In the same meadow in which it appeared last year, the Giant Swallowtail butterfly (Papilio cresphontes) floated above the flowers. The largest butterfly species in Canada or the United States (4-6 inch wingspread!), the Giant Swallowtail can beat its wings once and sail on gracefully for a long distance. However, it flutters constantly as it feeds, rather than landing to sip at blossoms. These swallowtails migrate like Monarch butterflies do – going south each winter. The females are larger than the males, so the one below must be a female. Perhaps her wings against the Queen Anne’s Lace give you a sense of how large – and how striking – she is!   

Male and female Monarch Butterflies (Danaus plexippus) are choosing both mates and tasty flowers as they dip and rise among the Bee-balm at Stony Creek.  The male has a slight bulge in one vein of each hindwing.  The female doesn’t.

A female Eastern Tiger Swallowtail (Papilio glaucus) soared high overhead, landing in a Wild Black Cherry tree  (Prunus serotina), a host plant on which her caterpillars can feed. She may have landed to lay her eggs on a leaf or she could be displaying her beauty and availability against the green leaves  for any interested mate. Tiger Swallowtails in our area mate once or twice each summer and their pupae overwinter in their chrysalises until next spring.

A female Tiger Swallowtail lands on a Wild Black Cherry tree that could act as a host plant for her caterpillars.

Far below, deep in the grass, a Cabbage Butterfly (Pieris rapae) landed on a grass stem. For the first time, I noticed the delicate architecture of the underside of its wings – and its long elegant antennae. Males have only a single spot on the fore and hind wing, so I think this is a male.

A Cabbage butterfly displays the intricate architecture on the ventral (lower) side of its forewing.

A curious predator, a female Common Whitetail Dragonfly (Plathemis lydia), watched me from a grass stem with great interest. Humans, after all, are so good at stirring up prey – easy pickings!  Love that face!

The Moist Woods:  A Fungus Fatale, a Pretty but Perilous Plant and A Mysterious Song in the Trees

Water Hemlock where the forest ends at the bottom of Stony Creek Ravine

Entering the cooler shade of the oak forest at Stony Creek Ravine, you begin to feel the moisture rising from the creek as it tumbles along far below. On my first park visit, it had rained the previous day so the ground seemed to exhale moisture as well. A perfect environment for mushrooms – and some very interesting ones! [Caution:  Please Never Eat a Wild Mushroom Unless a Trained Person Identifies It Definitively for You.  I Am Not a Trained Person.}

I first came across some fungi fatale – Amanita mushrooms (family Amanitaceae). Though squirrels nibble on them, they are highly toxic to humans. They are sometimes (not always!) recognizable by little warts on their surface and a collar that forms on the stem. Here are two just beginning to emerge from the soil on the path and a lovely mature white one, slipping out of a crack in the earth.

A maturing toxic Amanita mushroom

Small red mushrooms appeared along the woodland trail as well. Joshua Aaron on the  “Mushroom Identification” Facebook page identified these as members of a large worldwide genus of red mushrooms called Russula. Some are toxic, some not, so again caution is required.  Clearly some creatures gave these a nibble and decided to leave the rest.

Both Amanita and Russula mushrooms are fruiting bodies of those fabulous mycorrhizal fungi which help the trees reach and process nutrients from the soil while the tree feeds them its sugars created by photosynthesis. Helping a healthy forest along is another good reason to let them stay where they are and reproduce!

It turns out that a nearby plant, Indian Pipe (Monotropa uniflora),  which appears to be a mushroom, isn’t one. It’s more unusual –  a parasitic plant. Indian Pipes have no chlorophyll to use in photosynthesis like green plants do. Instead they tap into fungi, like Russula mushrooms, beneath the soil, feeding on the same sugars that the trees share with the fungi. It’s not too different from the way we tap maples for their sweet sap, is it?

Indian Pipe is a parasitic plant that feeds off fungi beneath the soil.

Nearby grew what folks at the Facebook page identified as Chanterelle mushrooms (genus Chantarellus), which, assuming that’s correct, would make them edible. I left them to disperse their spores undisturbed in the interests of both safety and respecting the natural state of our parks. One had fallen over so I got a good look at its fake gills, which are one of the signs of Chanterelles.

A couple of Bolete mushrooms had emerged among the oak leaves along the trail. These mushrooms (family Boletaceae) have pores below their caps instead of gills. They also belong to  a big mushroom group that includes both inedible and edible ones. Porcini mushrooms, for example, are boletes.

Walking along the ridge above the creek, I could hear a lone bird singing in the canopy of the oak forest – but it made no appearance.  I recorded its incessantly repeated song which reminded Ben and I of the rising and falling song of the Red-eyed Vireo (Vireo olivaceus) – but we’re not sure. Anyone able to give us a more confident identification? (Turn up your volume; it sings about three times.) [Second Edit:  Ruth Glass, local birder extraordinaire, now says definitively that this is the song of a Scarlet Tanager.  So I’ve again replaced the photo to show you a Scarlet Tanager. Thank you once again Ruth Glass!]

Although its song accompanied me for over an hour, the bird never emerged from the leafy treetops. So here’s what I missed – a photo of a Scarlet Tanager that I took at Bear Creek.

The Scarlet Tanager that I evidently heard but didn’t see. This is a photo from Bear Creek in previous years.

A plaintive song haunted the shady forest one morning – the questioning call of the Eastern Wood-Pewee. I could see this small bird in the high branches of a distant tree, but as soon as I moved closer, it moved farther off. So here’s a photo I took of one at Bear Creek Nature Park a couple years ago.

The Eastern Wood-Pewee sounds like it’s asking a question: “Pee-weeeeee?”

What seemed to be a juvenile Tufted Titmouse (Baeolophus bicolorhung from a vertically suspended branch in the forest. Its forehead patch (between the eyes)  was gray rather than black (hard to see in the photo) and its buff sides were less pronounced – field marks of a fledgling according to Stokes’ Guide to Bird Behavior (Vol.2). With its crest a bit ruffled, it looked as though it was not quite sure what to do next.

A young Tufted Titmouse considers its next move at the edge of the woods.

On one warm morning, I noticed two Mourning Cloak Butterflies (Nymphalis antiopa) dancing through the green dimness of the woods. Last fall, Morning Cloaks went into hibernation within hollow logs or under loose bark. There they freeze nearly solid during the winter, their cells protected by self-produced anti-freeze. Very early in the spring, often before the snow melts, they emerge, looking pretty ragged. They mate and reproduce so that by mid-summer, their young emerge. I’m guessing that’s why the ones I saw at Stony Creek Ravine appeared to have just wriggled out of their chrysalises. They were near perfect specimens. One landed, wings open, on a fallen log.

A fresh-from-the-chrysalis Mourning Cloak butterfly on a fallen log.

The other folded its wings, showing the underside  which closely resembles the tree bark under which they hide in the winter, camouflaging them with protective coloration. Quite a difference from the dorsal (upper) side of those wings, eh?

The underside of the wings of the Mourning Cloak provide great camouflage against tree bark.

Native grasses and plants thrive in the light, drier shade along the edge of the forest. I’m particularly fond of the arrow-like spikelets of Bottlebrush Grass (Elymus hystrix). Carrying their seeds inside, the spikelets eventually shoot along on the wind and then pierce the ground, giving the seeds a chance to spread and then be neatly planted.

Bottlebrush Grass has spikelets neatly arranged along its stem, giving the impression of a bottle brush.

Native Heal-all (Prunella vulgaris) is everywhere in shady areas. Some still believe it has medicinal value. I  like it for two reasons – the way its purple flowers protrude from its barrel-shaped calyx and the fact that when a raindrop hits the plant, the calyx flexes and flings out the seed.  I hope to see that someday!

Each little flower of Heal-all makes four tiny seeds that are flung away from the plant when hit by a raindrop.

Where the forest ends and the wetlands begin at the bottom of the ravine, a flower fatale flourishes – Water Hemlock (g. Circuta). Every part of this plant is toxic to humans and other mammals (but as I’ve said before, who would eat it?) – so avoid the fate of Socrates and just admire its big, umbrella-shaped blossoms nodding in the breeze. Many insects, however, feed on Water Hemlock, and it hosts the caterpillars of Black Swallowtail butterflies!

Water Hemlock grows in the ravine with big umbrella-shaped blossoms. While toxic to mammals, this plants helps us enjoy more Black Swallowtail butterflies!

An iridescent cloud of male and female Ebony Jewelwing Damselflies (Calopteryx maculata) darted in and out of the shadows near the creek. These predators of many species are also the prey of many. So thank goodness these beautiful creatures lay lots of eggs!

Nearby in patches of sunlight grew golden stands of a lovely wetland flower called Fringed Loosestrife (Lysimachia ciliata). This native wildflower modestly bows its blossoms toward the wet soil waiting for a Melittid bee to come along. These native bees specialize on this flower, feeding its oils and pollens to its larvae. Fringed Loosestrife can also spread by rhizomes beneath the soil.

Fringed Loosestrife loves “wet feet” and partial shade. It blooms in sunnier patches near the edge of Stony Creek.

If you turn up your volume, perhaps you can hear the babble of Stony Creek as it finds it way over stones in the ravine. Such a soothing sound. But you don’t need to traverse the steep sides of the ravine and get wet feet. You can simply rest on the high ridge where the trail ends and watch the water sparkle as the creek rounds a graceful curve right below you. Combined with the birdsong in the treetops, the whispering of summer leaves, and the flutter of butterfly wings, you should walk back out of this little park feeling a bit more mellow than when you walked in.

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 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.

Goldfinch in willow GC
A male goldfinch settles in the willow trees, resting from his singing flight in the golfinch mating season.

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.

Rabbit GC

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!

Eastern Wood-PeeWee
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.

Joe Pye GC
Joe Pye and Goldenrod complement each other near the creek where the reeds are growing in the background.

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.

Out and About In Oakland: Stony Creek Ravine – A Park Less Traveled

The diversity of Oakland Township’s parks and natural areas is a source of repeated surprise and delight  for me.

Blog post and photos by Cam Mannino

In the last few, very hot weeks, my husband Reg and I have explored the cool, shady trail that threads its way through Stony Creek Ravine Nature Park, a hidden gem that is still under development by the Parks and Recreation Commission. Be prepared to feel you are up north or even out west as you wind your way along a high ridge overlooking the creek.

The 0.4 mile hike isn’t long but it is dramatic. You begin in a tunnel formed by tall shrubs.  Here Reg stops to listen to birdsong as we enter the park.

Path to the Woods Reg SCR
Birdsong can be heard  all around you when you enter Stony Creek Ravine Nature Park.

Gray Catbirds meow from the thickets, Black-capped Chickadees scold on nearby branches – and birdsong flows down from the treetops, trilled by cardinals and other songsters that I don’t yet recognize by ear.

Black-Capped Chickadees (Poecile atricapillus) search the trees for the insects and spiders that make up most of their diet at this time of year.

Occasionally the trail opens to reveal grassy areas filled with wildflowers.  Ben and his summer technicians have worked hard to restore some of the open areas that once existed here.

Native plants like Bee Balm (Monarda fistulosa) again find a home here as restoration continues in the park.

By ridding areas of invasive shrubs,  native wildflowers and grasses like these below find a home here once more.

Mushrooms grow on the moist, steep sides of the ravine. This one appears to be a mushroom from the genus Amanita, mushrooms toxic to humans. Squirrels, though,  eat them with no ill effect.I think a nip’s been taken out of this one, actually.

AManita muscara mushroom SCR
Toxic Amanita mushrooms are perfectly edible for squirrels.

Of course, all the flowers attract the bees and butterflies who share your walk. For a few minutes, a Bumblebee (genus Bombus) seemed to be enjoying riding down thin stalks of Narrow-Leaved Plantain (Plantago lanceolata) in the middle of the trail. This small bee seemed to be working awfully hard for the limited nectar or pollen on these plants. Maybe it was just a youngster having a good time or practicing its technique?

Where there’s water, of course, there are damselflies. Ebony Jewelwings (Calopteryx maculata) balance on the leaves at Stony Creek Ravine and can be seen in groups down near the water.

Along the trail, you’ll see the remains of a farmer’s old stone wall, evidence that this land was once more open and sunny than it is today.

The land begins to fall away on either side of the path, plunging dramatically down to Stony Creek as it winds its way through the narrow ravine below. What a view! And the grade is much steeper than a photo can even make it look!

Stoney Creek Ravine
Stony Creek winds its way through the ravine from which the park got its name.

It’s important to stay on the trail here since the stream bed is a conservation area and downhill sliding and slipping causes erosion and damage.  Here are some of our native plants that find a home at the bottom of the ravine, right near the water.

White-Tailed Deer (Odocoileus virginianus) are prevalent in this park. The Parks and Recreation Commission allows controlled hunts in this park every Tuesday and Wednesday from October 1 to January 1, with a PRC-issued special license, to provide opportunity for hunters and to manage the high density of deer in the park. Since the park is closed on those days for 3 months, come visit this slice of dramatic beauty on different days or during the other 9 months of the year .

Currently the park’s trailhead is at the end of Knob Creek Drive which is off E. Gunn Road. Right now there is only room for one car to park off-road at the entrance. The PRC applied for a grant to help purchase an adjacent 209 acres to expand this park – an area full of  wildflowers and the wetlands that birds and amphibians love, plus space for plenty of parking off Snell Road.  Fingers crossed that we receive that grant!

The trail takes you to a great vantage point and then ends within the park’s forest of sturdy oaks and their saplings.  When you turn to walk back, you’ll be surprised, I think, by how much you notice that escaped your attention on the way in.  I always am.

We all probably have our favorite natural areas in Oakland Township.  Mine’s always been Bear Creek Nature Park and yours may be the Paint Creek Trail or Cranberry Lake Park. But it’s exciting to explore the paths “less traveled by” with fresh eyes. Beauty takes so many forms in the natural world and I love being introduced to landscapes nearby that I’ve never seen before. Give it a try. You never know. As poet Robert Frost suggested, taking one of these paths “less traveled by” may make “all the difference.”

THIS WEEK AT BEAR CREEK: Flocking Birds, a Winter Resident from the Arctic Tundra and Some “Lovely but Lethals”

Russet trees across Eastern meadow

Winter chill showed up last week – along with sparrows arriving from the arctic tundra.   Small migrators, just passing through on their way south, huddled among bare limbs.  Fall inspires birds to flock and the skies and trees are crowded with bird society.  A few wildflowers are still sending off or dropping their last fruits and all kinds of leaves whirl down and carpet the paths.  Now is the time when the negative impact of too many deer and invasive plants becomes readily apparent – so we’ll explore “lovely but lethal” creatures and plants in the park as well.

Birds Flock Together in the Chill Winds

Evidently, wildlife experts have various theories about why birds flock in the autumn.  The most common explanation seems to be that it’s protection. More bird eyes and ears can spot predators and find food more easily.  In some species,  the young flock with adults who know more about food sources than they do.  Some experts believe birds learn from other birds about new food sources by hanging out in flocks or rookeries.  Migrating is easier in flocks in which individual birds take turns flying in front, thereby decreasing the wind resistance for the birds behind them.

And then there’s the possibility that birds are just more social when they aren’t courting or raising young.  American Robins (Turdus migratorius) for instance, are chirping all over the park now in small flocks, often high in the treetops.  Many robins spend their whole winter here; we just don’t see them on the lawn because they can’t get to worms, so they eat fruits during the cold season.

Mallards (Anas platyrhynchos) gather in large numbers in the marsh.  I saw a flock of over 50 last week floating and flying near the Gunn Road end of the marsh – and heard reports of hundreds near Rochester Road.  Here are about half of the ones I saw.

29 Ducks in marsh

Turkey Vultures (Cathartes aura), often seen in ones or twos over the western Old Field during the summer, were soaring in groups of five or more this week.  Our “cleanup crew” with its magnificent 6 ft. wing span will soon be gone, migrating to the southeast to spend the winter.

Lately I’ve learned that flocks of Black-Capped Chickadees (Poecile atricapillus) are good places to look for other small birds who hang out with them when in unfamiliar areas.  Their “Chickadee-dee-dee” call ends up being a clue to look for fellow travelers like the sparrows below.  The reason?  Chickadees are great at sounding alarms that other birds heed.  The more “dee’s,” the higher the threat.  And as year ’round residents, they probably know the best, closest food sources as well.  This Chickadee mustered its impressive balancing skills to take off in the stiff winds this week.

Snag w chickadee woodpecker holesEver wonder how a bird as small as a Chickadee survives during cold, rainy nights like we had this week or cold snowy ones? Cornell Lab says that these tiny birds can excavate their own individual holes in the rotting wood of snags (standing dead trees)  – one bird per hole!  I’m glad to hear that, since I know chickadees always face the challenge of eating enough to stay alive in cold weather. They store individual seeds everywhere and then can actually remember where they put thousands of them! Here’s how Cornell says they sort of “clear their hard drives” at this time of year: “Every autumn Black-capped Chickadees allow brain neurons containing old information to die, replacing them with new neurons so they can adapt to changes in their social flocks and environment even with their tiny brains.”  Wish I could do some of that!

Cold Weather Sparrows Arrive While Sparrow Visitors Pause and Move On.

This winter, flocks of  Tree Sparrows (Spizella arborea) will probably gather beneath your bird feeder as well as mine.   These distance travelers have spent the summer raising young on the arctic tundra and this week arrived back at Bear Creek.  See this link to their beautiful arctic nests made of ptarmigan feathers.  These small birds with their warm brown caps and black dot on a gray chest must love cold weather since they clearly think our winters are comfortably mild.

Tree Sparrows arrived this week from their summer homes on the arctic tundra.

Other sparrows are still just passing through.  The large Fox Sparrow (Passerella iliaca) with gray above its eye and on the nape of its neck is heading for backyards and fields anywhere south of mid-Ohio.  This one looks especially red-brown because it was basking in the light of a setting sun.

This is probably the last week that the White-Throated Sparrow will be at Bear Creek. Its yellow “lores” (spots in front of the eyes) are present at the top of the beak, a bit faint in this photo,  but it had the classic field marks of a white throat and striped head – when it would emerge for a few seconds from hiding among the branches!

The Hermit Thrush (Catharus guttatus) was here last week, foraging near the Center Pond as the leaves thinned out.  With the cold north winds late in the week, it’s probably winging its way to Tennessee and points south, like the human “snow birds.”

Seeding for Spring Continues

3 Common Mullein
Three non-native Common Mullein plants stand like morning sentinels on the western slope of the park.

Like the tall non-native Common Mullein (Verbascum thapsus) above, many wildflowers have finished seeding for the year, but some are still dispersing seeds in a variety of ways.  The native Buttonbush (Cephalanthus occidentalis), that looks like a tiny white sputnik when it flowers,  is now drooping in the marshes. (Rest your cursor on double photos like this for captions.)

But it’s been a great help to the native wildlife around it.  According to Wikipedia, “Waterfowl and other birds eat the seeds. Wood ducks utilize the plant as nest protection. Deer browse the foliage. Insects and hummingbirds take the nectar, with bees using it to make honey.”  That’s what makes many native plants good for a habitat – lots of uses for native wildlife.

Remember the loose sprays of native Water Hemlock (Cicuta maculata) that were in or near every park wetland during the summer? This plant, the most toxic in North America, is now making a delicate, brown fruit with tiny hooks that attach to animal fur –  or my cotton sweater as I wade into the plants to get a macro photo.  In that way, they spread their seeds for next spring.

Native Gray Dogwood (Cornus foemina) has fed lots of birds with its white berry-like “drupes” this fall and now leaves behind a lovely red fringe at the edge of the marsh in the center of the park.

Common Milkweed (Asclepias syriaca) pods are drying and mature seeds are now being released to the wind.  If you see seed on the path or anywhere they can’t sprout, pick them up and send them flying!  The resident and migrating Monarch Butterflies (Danaus plexippus) that feed on them next summer will thank you.

By the Way..

One Tough Dragonfly!

I was astonished on Friday, after the heavy, cold rain and high winds, to still see another Yellow-legged Autumn Dragonfly (Sympetrum vicinum) calmly sitting on the railing at the Playground Pond.  On Sunday a week ago, I’d seen the one in the photo below on a matching red leaf at Seven Ponds and thought that would be my last sighting of the year.  That is one tough insect!  At Bear Creek, a few grasshoppers were still chirping, a bit forlornly, in the tall grass as well and could still be seen springing about on southern slopes in the park.  Amazing.

And Just One Special Leaf this Week:

Isn’t the Quaking Aspen (Populus tremuloides) a lovely tree? They shimmer silvery green in the summer and shower golden leaves in the fall.  It’s a very common and short-lived tree with smooth, light bark that’s often mistaken for birch. And as Michigan Flora says, it’s “one of the few deciduous trees of the boreal forest to the north of Michigan.”  Another resident from the far north! That Tree Sparrow must have passed thousands of them on the way here.  Maybe that’s why I saw my first Tree Sparrow of the year right across from the Aspens on the park’s northern loop.  This week, in those stiff winds and rain, the Aspen’s dancing leaves went flying, leaving a carpet of gold on some paths at Bear Creek.

Now for those “Lovely but Lethal” Plants and Animals

It’s tough not to love White-Tailed Deer (Odocoileus virginianus).  After all, who doesn’t love to see those “doe eyes” gazing our way?

Deer
An over-abundance of the lovely White-tailed Deer can be a problem to native wildflowers and the tree canopy, especially in woodlands like our Oak-Hickory forest.

However, deer are seriously over-populating the landscape here and elsewhere.  According to the Nature Conservancy, “No native vertebrate species in the eastern United States has a more direct effect on habitat integrity than the white-tailed deer.”  The huge number of deer changes the landscape as they prefer to eat native plants, like Common Trillium, for instance. This feeding has reduced the density and height of forest wildflowers and make more room for invasive plants to spread.  Their consumption of acorns  also has an effect on the tree canopy in the woods. Deer are native to Michigan and much-beloved by both nature-lovers and hunters, so finding a solution to their over-abundance is a real challenge.

bittersweet
This invasive lovely and lethal vine that people admire in the fall chokes the life out of trees and bushes.

As we posted separately, one of the worst actual killers in our parks is Oriental Bittersweet (Celastrus orbiculatus) – which was very apparent this week in the park.  Its yellow leaves, yellow capsules and red fruit can be seen from every path twisting its way up and across trees and bushes.  Introduced as a landscape plant, this striking but lethal vine kills trees and bushes in three ways.  It  winds aggressively around the trunks of trees to get to the sunlight at the top, girdling the tree until it chokes the tree to death.

bittersweet killing small tree
Oriental Bittersweet, a beautiful invasive vine,  will eventually kill this small tree by girdling it and robbing it of nutrients and sunlight.

It also creates so much weight at the tops of trees that once they are weakened by the Bittersweet, they can be blown over in the wind.  They also climb over bushes so densely that they simply steal the sunlight and nutrients from the host plant and any plant nearby.  So please don’t pick it, don’t make or buy wreaths of it and don’t try to pull the heavy vines down yourself because you could get seriously hurt! Please see our post on how to rid our parks or your property of this beautiful killer.

Autumn Olive (Elaeagnus umbellata) has been the bane of Bear Creek for a long time.  The northern end of the park is full of this invasive bush with its fragrant flowers in the spring and its red berries in the fall.  This woody shrub can literally crowd out native shrubs and plants as it has, along with other invasives , on the large loop at the north end of the park.

Now a new invasive tree is competing to be the most problematic and it too is lovely.  (Most invasives are pretty; that’s why people plant them in their landscapes!)  Friday morning I counted 16 small to medium-sized trees of this new problem for Bear Creek in one small corner near the center pond. It’s called Callery Pear (Pyrus calleryana) – another lovely, but lethal invasive plant.

Callery Pear invasive tree
A new invasive plant has found its way into Bear Creek – Callery Pear. There are 16 trees of varying sizes already at this corner near the Center Pond.

Of course, native trees can get out of hand, too, like Box Elder (Acer negundo), actually a not-so-wonderful kind of maple . Box-elder samaras seedsLook at the number of samaras (a fruit with wings attached to carry seeds)  in this one small clump on a large tree at the bottom of the western slope.  There are a lot of box elders on the western slope for that very reason!  Though the multiple trunks are often thin and the trees are short-lived, it can quickly colonize an area and crowd out other trees and plants.

 

 

Nature is remarkably resilient.  If we can give it a bit of help through careful stewardship, we can control these lovely and lethal plants and animals so the native ones can take their proper place in the landscape and the non-native ones can slowly be eliminated or at least controlled so they don’t irrevocably change the diverse native landscape that nature provided for us.  So consider joining in our stewardship events (see the Stewardship Events tab above) as we weed and plant to help Bear Creek and our other parks thrive in all their natural glory.

A note about “This Week at Bear Creek”:  My blog posts will probably slow some between November and February since late fall and winter are more static times in the park – and occasionally the weather will make it tricky to get out with my camera!  So please consider “following” Natural Areas Notebook, so that you’ll get an email when a post goes up.  I love doing this blog, so whenever I see some changes in the wildlife or something unusual in the park that I think might interest all of you this season, I’ll be here!  Thanks so much for your support and interest as we made our virtual walks together through the spring and summer!  Let’s see what late fall and winter bring!
