Watershed Ridge Park: Restoration Off to a Colorful Start!

 

Wildflowers re-establish themselves in a meadow at Watershed Ridge after invasive shrubs are removed

Watershed Ridge, at the corner of Lake George and Buell Roads, is not yet an accessible park. Trails have yet to be created for exploring its forests, wetlands and meadows, though they are planned for the future. Large areas of the land are still under cultivation for agriculture; local farmer, John Fogler, rents fields within the park to plant soy beans and pumpkins. (Click on photos to enlarge; hover cursor for captions.)

But last fall, our Natural Areas Stewardship Manager, Ben VanderWeide, began removing an almost impenetrable cover of invasive bushes that had taken over part of this beautiful piece of land. And suddenly, the graceful contours of the land came into view.

The rolling slopes looked lifeless then. But what a transformation this spring and summer as sun finally reached the native wildflowers!

Part of the reason Ben chose this area for restoration was that he’d noticed unusual native plants struggling to survive in the shade of invasive bushes like autumn olive, glossy buckthorn, privet, and such. Last autumn, Smooth Aster (Symphyotrichum laeveand a small orchid called Ladies’ Tresses (Spiranthes species) thrust their stems into the cool air. (Here’s a photo of the little orchid as it looked at the Wet Prairie on the Paint Creek Trail.)

Ladies Tresses, a small orchid, is a fall wildflower that Ben saw at Watershed Ridge last autumn.

Right now I’d advise anyone to be cautious about  walking through Watershed Ridge since it’s easy to get disoriented on 170 acres without trails (though a compass in your phone helps, I find!). Hikers need to use the edges of the farm fields so that they don’t damage the crops. The woody debris on the ground makes walking a bit tricky  and there’s a fair amount of Poison-ivy (Toxicodendron radicans) to avoid. Photos below might help those afraid of all 3-three-leaved plants. The one on the left is poison ivy.  Note the “thumb” on the leaves which is missing from other three-leaved plants like the Black Raspberry (Rubus occidentalis) on the right. Poison-ivy often has reddish “feet” when it’s climbing a tree and grows along the trunk rather than around it.

So for now, perhaps consider an easier alternative.

Birds Grace the Simple Entrance off Buell Road

The best spot to park is on Buell Road at the firewood pickup site (1650 W. Buell Road is the approximate address – click here for a map). Just to the west you’ll see a work area for Parks and Recreation staff that includes a pole barn and bulk materials storage. This work area is closed to the public, but you’re welcome to explore the rest of the park.

The old fence rows near the entrance on Buell Road have many trees, shrubs and vines, so birds nested happily around the area this summer. In mid-July, this area was full of fledglings trying out their wings and pestering their parents. A flock of young Eastern Bluebirds (Sialia sialis) settled on limbs and fence posts, begging to be fed while their beleaguered adults either surrendered or tried to escape their noisy youngsters. (Click on photos to enlarge; hover cursor for captions.)

A young Eastern Phoebe (Sayornis phoebe), however, was off on its own, trying out its wings, exploring the pole barn (sheds are popular Phoebe nest sites) and flying down into the grass like any adult Phoebe might.

A young Phoebe exploring the shed at Watershed Ridge – a very typical behavior for a bird that often builds nests in human structures.
The same Phoebe in a nearby tree to provide a glimpse of how small this little flycatcher is!

A young Downy Woodpecker (Picoides pubescens) was also off on its own and looking a bit dubious about what to do next as it sat in a nearby pine. This may be a young male since it appears that its juvenile red cap is slowly receding into the red spot that a male sports on the back of its head.

A juvenile Downy Woodpecker considers what to do next.

I failed to get decent photos, but two weeks ago, a pair of Cedar Waxwings (Bombycilla cedrorum) were still feeding their nestlings, flying back and forth between a tree on the west side of the area to a large willow on the east where they probably were foraging for insects before returning to the nest. Here are two not-so-hot photos!

From mid-July to mid-August, American Goldfinches (Spinus tristis) raise their young. Unlike most native birds, they wait until mid-summer to breed, because they like to line their nests with thistle down, eat the seeds themselves and feed them to their young. Several were flitting among the thistles along Buell Road.

A “High Quality” Woodland Sprinkled with Wildflowers that Love Moisture, Shade and Rich Humus.

When you step into the cool darkness of the woods on a warm summer afternoon, you notice that most of the plants bear modest little flowers compared to sunnier areas. Perhaps that’s because they’ve  evolved growth and reproductive strategies that are different from the large, colorful blooms of a sunny meadow or prairie.

One good example is the unusual flower of a parasitic plant (not a mushroom!) that Ben helped me find, called Indian Pipe (Monotropa uniflora). This small, white wildflower typically grows in forests and lives on the photosynthesis of trees – especially oaks in our area – by tapping into the  mycorrhizal fungi that connect the trees below the soil. As a result, it doesn’t use photosynthesis and contains no chlorophyll. According to the Illinois Wildflower website (a descriptive floral site), “This unusual wildflower is normally found in high quality woodlands” where there is “abundant humus.”  Hooray for Watershed Ridge, eh?

The modest blooms of summer woodland plants primarily attract small bees, like sweat or carpenter bees,  or flies,  rather than honeybees or bumblebees.  They also frequently spread by rhizomes (underground stems) and/or by making bur-like fruits that will stick to any passing animal, including you!

Wildflowers that enjoy dappled light find a home where the woods meets the now-open meadow.

Naturally, mushrooms also thrive in shady, moist places. Near the edge of the woods, I saw what I think are two kinds of highly toxic mushrooms from the genus Amanita. I believe they are either Amanita phalloides or Amanita bisporigera. In any case, Amanita mushrooms are also called “death caps” for good reason –  so admire their exotic strangeness, but leave them right where they are. The yellow one may have been nibbled by squirrels or rabbits who can eat the toxins with no problem.

Wetlands Glow Blue/Green in the Deep Shade of the Woods

One of the wetland pools within the woods at Watershed Ridge

Two wetland pools shine in the darkness on either side of a ridge within the woods at Watershed.  Near the western one, an old log is festooned with a huge number of tiny, stalked mushrooms which I can’t identify. They make quite a show against the dark, wet decaying log on which they are thriving.  (Anyone have an ID for me?)

Ben saw two snappers on a log in one of these woodland pools, but they dove in before I saw them. I did see some of my favorite frogs, though. A small female Green Frog (Rana clamitans) (left) basked on a fallen log, while a male nearby (right) did the same. In the female, the tympanum (circle behind the eye used for hearing) is about the size of her eye; the male’s tympanum is about twice the size of his eye and he has a yellow throat.

At the eastern pool, a tiny, black-masked Wood Frog (Rana sylvatica), perhaps 1/2 inch long, paused for its photo on a leaf. This one’s back and legs are bright green, perhaps from the Water Meal (Wolffia columbiana) or the algae in the pool nearby. It seemed an odd time of year  to find an early spring frog, but Wikipedia says that  occasionally Wood Frogs do breed more than once per year. Maybe the heavy rains contributed to more water and hence more breeding behavior? Just a guess.

At the edge of the soybean field just beyond the wood, every step scared up hundreds of small Northern Leopard Frogs (Rana pipiens). They sprang out of moist grass and huddled beneath the bean plants. These young frogs  take about 70-110 days to develop after the females lay their eggs in the water between May to June. At about 2 inches long, they’re half the size of a mature Leopard Frog. Their numbers have generally been in decline since the 1970’s so what a delight to see so many of them here in the township on a protected piece of land!

A Riot of Color as Wildflowers and Butterflies Reclaim a Wild Meadow

Black-eyed Susans and Butterfly Milkweed “take the field” after invasive shrubs are removed from Watershed Ridge

Step out of the woods and the colorful signs of restoration engulf you. Once shaded-out by invasive shrubs, native wildflowers like Black-eyed Susans (Rudbeckia fulgida) and Butterfly Milkweed (Asclepias tuberosa) in the photo above sprang back into the sunlight that finally reached them.  So exciting to see these plants come back with such vigor in the first season after the invasives are removed! (Use pause button to read captions.)

And with the wildflowers, of course, come the butterflies – but first, one glorious moth! When I first spotted this unusual creature, I thought it must be some sort of bumblebee. But no, it’s the Snowberry Clearwing Moth (Hemaris diffinis). It has fewer central scales on its wings than other butterflies or moths so the wings appear clear in places. It’s odd shape and hovering flight have also inspired the names “the hummingbird moth” (not to be confused with the European one of the same name, Wikipedia tells me!) or the “flying lobster!”  A new creature for me!

This is not a bumblebee. It’s a Snowberry Clearwing Moth mimicking one!

On my first summer visit with Ben, we saw a glorious Eastern Tiger Swallowtail (Papilio glaucus) sipping from some of the bee balm which emerged in great waves of color across the restored meadow this summer. What a sight!

A female Eastern Tiger Swallowtail sips nectar from the great swath of bee balm that now flows across the restored meadow.

Having seen the Spicebush Swallowtail butterfly (Papilio troilus) for the first time at Charles Ilsley Park a few weeks ago, I saw another male at Watershed Ridge.  The clue is the wash of blue scaling on the wings. A week later I saw another one near the shed which was either the female, which has a less intense wash of blue scaling, or a tattered male who had already lost some of his scales. That Spicebush continually tried to chase off a female Monarch (Danaus plexippus) who was patrolling the same patch of flowers last weekend. The scales on her wings looked quite worn as well. Perhaps they’d worn each other out with all that chasing! I saw some fritillaries dancing together at a distance but not close enough for a shot. But the little Orange Sulphur  (Colias eurytheme) was kind enough to pose for a few moments.

The meadow slopes down to a sunny wetland that is probably fed by the creek running through the trees just east of the meadow. The stream bottom is bright orange, most likely a result of iron deposits in the soil. I loved how the sky was caught in the water’s surface as I looked upstream.

The resulting wetland at the meadow’s edge featured flowers that love “wet feet,” like Joe Pye Weed (Eutrochium maculatum) and Boneset (Eupatorium perfoliatum).

With a wetland nearby, dragonflies, flying predators, swooped across the meadow on the hunt for other insects.

A Meadow Under Restoration Gets Us Dreaming

Another view of the meadow that is slowly being restored at Watershed Ridge

Witnessing the dramatic renewal that takes place when invasive shrubs are removed from park land is simply inspirational. What else, who else might return to this lovely piece of land once the Parks and Recreation Commission has time and the funds to develop this 170 acres? What seeds are waiting in the seed bank for their turn in the sun – perhaps even this autumn when the asters in their varied lavender-to-purple blooms or other autumn wildflowers rise from the earth? What other exotic creatures like the Snowberry Clearwing Moth might be sipping at future flowers? What birds might return to nest here? The possibilities are endless as the Ben and the Parks Commission work to renew the diversity of life which is our township’s natural heritage. So much to look forward to as this park progresses over the next several years!

OUT AND ABOUT IN OAKLAND: LOST LAKE – Big Birds, Big Hill, Big Diversity of Life

Cam walking into BC
Blog and photos by Cam Mannino

Until recently, I’d visited Lost Lake Nature Park (on Predmore west of Cranberry Lake Park) only in the winter and marveled at its amazing sledding hill. I’d spent a delightful snowy afternoon taking action shots of kids and adults as they whizzed by on their sleds during Winter Carnival. Fun place! I’d visited once in spring with  the birders and seen a cloud of Yellow Warblers whisking through the trees at the top of the hill.

But it occurred to me that I didn’t know what this 58 acre park had to offer in the summer. So for the last couple of weeks, I’ve spent quiet hours watching water birds as I explored around the 8 acre “kettle lake.” I hiked up through the woods after a rain and was astonished by colorful mushrooms of all shapes emerging at every turn in the path. I ambled down the sled hill in the sunshine among native wildflowers and swooping dragonflies. Let me show you a sampling of what I found.

Lost Lake Itself and Its Wetlands

lost-lake-w-deck
Lost Lake is a “kettle lake” left by a retreating glacier.

As the audio sign near the lake explains, about 10,000 years ago, an “isolated block of glacial ice melted and filled a depression, or ‘kettle,’ in which it sat.” Kettle lakes are “natural wells, refreshed by groundwater springs.” Wetlands encircle the lake. Right now, the cat-tails and reeds near the water are fringed with early fall wildflowers. A sapphire blue one , with a name that sounds like an exclamation – Great Blue Lobelia (Lobelia siphilitica) creates a striking contrast against the yellow Canada Goldenrod (Solidago canadensis) and Riddell’s Goldenrod (Solidago riddellii).

great-blue-lobelia-ll
Great Blue Lobelia is plentiful on  the southern edge of Lost Lake.

The cheerful blooms of Nodding Bur-Marigold/Nodding Beggar-Tick (Bidens cernua) edge the shore near the floating dock. It’s a native annual that spreads through re-seeding in the fall.

nodding-bur-marigold-ll
Nodding Bur-Marigold, also called Nodding Beggar-tick, is a native annual.

In the water nearby, graceful spikes of lavender rise above the water. These lovely native plants have the unlovely name of Pickerelweed (Pontederia cordata), clearly named by a fisherman who appreciated his catch more than the flowers nearby! Found in “high quality wetlands,” according to the Illinois Wildflowers site, it produces large fruits occasionally eaten by ducks.

pickerel-weed-ll
This graceful. aquatic native, has the unlovely name, Pickerelweed!

Lavender and yellow seem to autumn’s chosen colors when it comes to wildflowers. The Yellow Coneflowers (Ratibida pinnata) of summer that edge the parking lot are waning and the Smooth Asters (Symphyotrichum laeve) are beginning to emerge among them.

Large portions of the pond are dotted with native Fragrant Waterlilies (Nymphaea odorata). I couldn’t catch their sweet scent, but lots of little creatures – beetles, small bees, flies –  evidently can. These elegant blooms produce abundant pollen. Turtles, beavers, muskrats and the occasional deer wade in to feed on the huge, round leaves.

water-lily-closeup-ll
Fragrant Waterlilies produce abundant pollen for insects and their leaves provide foods for muskrats, turtles and beavers.

According to the Illinois Wildflowers website, Waterlily blooms last 3 or 4 days, but once the petals wither, a fruit develops whose stalk bends downward so it can mature underwater. When the seeds are ripe, they are released and float to the surface where they’re carried by water and wind until they sink to the bottom for germination. I saw new blossoms on every trip because of buds like these (love the  neatly-folded, small green bud below the big yellow one!).

[Edit:  I forgot to include a small Green Frog (Rana clamitans[) that I caught peeking from between the lily pads.  Like the juvenile birds who seem to grow into their beaks, I wonder if little frogs like this one need to grow into their enormous eyes! Lovely how the sunset that evening colored its small world.]

green-frog-among-lilypads-ll
A small Green Frog came out from between the lily pads as the setting sun turned the water golden.

Under the water, I saw small fish of various sizes schooling. The audio sign indicates that several different species live in the lake, including bullhead, blue-gills, perch, bass and northern pike. What I saw, I think,  were Minnows (family Cyprinidae).

minnows-lost-lake
Evidently perch, bass, blue-gills and others live in Lost Lake but I  saw only Minnows.

Twice as I approached the lake, I was greeted by the site of large water birds. One morning two Great Egrets (Ardea alba) stood at the eastern edge of the lake.

egret-adult-and-juvenile-ll
What appears to be an adult egret with a juvenile at the eastern edge of Lost Lake.

I thought perhaps the larger was an adult and the much smaller was a juvenile. The larger one preened and both foraged for frogs and small invertebrates in the mud at the edge of the pond. After 20 minutes, the large one took off flying and the small one followed. They simply circled for a few minutes and then landed to eat again. I wondered if the older was helping the younger strengthen its flight muscles for migration. Just a guess, though.

egrets-taking-off-ll
The egrets took off and circled for a few minutes before settling to eat again.

While watching the egrets, a large flock of Canada Geese flew overhead, calling to each other. The egrets looked up and watched, just like I did. (Hover cursor for captions; click on photo to enlarge.)

On my second visit to Lost Lake,  a pair of Sandhill Cranes (Antigone canadensis) waded and foraged in exactly the same area that the Great Egrets had used on my previous visit. Sandhills are grey birds, sometimes with what Cornell Lab calls a “rusty wash.” I’ve read, too, that they use mud to preen which often makes them appear brown. Seeing them dancing gracefully up in the air and floating down when mating in the spring is a sight to behold.

sand-hill-cranes-ll
On the following visit, a pair of Sandhill Cranes foraged in the same area as the egrets.

The Woods: An Oak-Pine Barren

Near the pond, a wide variety of trees tower overhead – Cottonwoods (Populus deltoides), Paper Birch (Betula papyrifera), White Oak (Quercus alba) which is already producing bright green acorns and a variety of pines, including huge White Pines (Pinus strobus). The dry, sandy acidic soil here support an Oak-Pine Barren, a special plant community where the most common trees are widely spaced pines and oaks. To mimic the frequent fires that maintained the open tree canopy, the Natural Areas Stewardship crew burns the woodlands at this park every few years with careful use of prescribed fire.

The path to the woods goes west from the lake, beyond the vehicle barrier signs in front of the Nature Center. Along the way, a native perennial, Bee Balm/Wild Bergamot (Monarda fistulosa) fills a sunny spot along a fence line.

bee-balm-ll

On a moist morning after a downpour, I followed the short path that winds up through the woods toward the top of the sledding hill.

forest-lost-lake
The path that starts west of the lake leads through the woods to the top of the sledding hill.

The warmth and moisture had caused the appearance of an astonishing variety of mushrooms, which are the “fruiting bodies” of the fungi living under the soil. Mushrooms produce the fungi’s spores above the soil surface so that they can be scattered for reproduction. In that way, they are like the blooms of flowers carrying the seeds for next year’s crop. But what a diversity of shapes and colors on one morning alone! Below is a gallery of mushrooms, some beautiful, some homely, but all ready to disperse spores on the same damp morning.

Click on the photos to enlarge but I’m afraid I can only tentatively identify a couple of toxic ones. The tall, thin white one with a cap appears to be an early stage of  the dramatically named Destroying Angel (Amanita virosa) mushroom. It belongs to the toxic genus Amanita, which probably also includes the  red or red-and-white mushrooms pictured hereAnd the green mushrooms on tree bark are probably a shelf fungus called Turkey Tail (Trametes versicolor).

Along with oaks and pines, the woods has many Sassafras trees (Sassafras albidum) with their distinctive 3-pronged leaves that smell like root beer when plucked. Sassafras evidently thrives in the sandy soil which underlies a Oak-Pine Barren like this. Here are the huge leaves of a tiny sapling trying to make the most of the forest light.

Nearby by, a black lump of mud seemed to jump in deep shade. Looking closer, I spotted a  very small Eastern American Toad nicely camouflaged against the forest floor. See if you can spot it; it took me a minute when focusing my camera!

Here it is up close.

Here’s the little creature up close.

Near the top of the sledding hill, at the edge of the forest, native Bottlebrush Grass makes an appearance. The unusual shape of its “awns” (bristle-like appendages) seems to mimic the pine needles nearby and its pale stalk lights up in the smallest amount of sunlight.

Back Down the Big Hill: Sunshine and Prairie Plants

Emerging from the forest shade and descending into the bright sunlight at the bottom of the hill, you’re suddenly surrounded by dry prairie plants of all kinds. Right now,  plumes of Showy Goldenrod (Solidago speciosa) glow in the fall sunshine and native Bumblebees (genus Bombus) hover among the blossoms, making the most of late-season nectar.

showy-goldenrod-ll

All kinds of native grasses thrive from the top of the hill to the bottom – Big Bluestem (Andropogon gerardii), Little Bluestem (Schizachyrium scoparium) and Indian Grass (Sorghastrum nutans).

Ruby Meadowhawk dragonfly (Sympetrum rubicundulum) kept me company as I descended the hill, even quietly posing for a closeup on a beautiful stalk of Big Bluestem.

What I think was a Violet Dancer damselfly (Argia fumipennis) hovered along the path as well. Damselflies seem to love places where a forest meets an open meadow.

Stopping back at the lake at the end of one walk, some frantic activity at the edge of the water caught my eye. Amazingly, four pairs of Ruby Meadowhawks were mating simultaneously! Linked together, each of the four pairs rose and fell, quickly dipping into the water and then zooming upward again. Here’s the best blurry photo I could get of the 4 pairs enacting their dragonfly drama.

Four Ruby Meadowhawk pairs beginning the mating ritual at the same time.

A male begins the mating ritual by grasping onto the female right behind the head with pincers at the end of his abdomen. Then the two bend toward each other so that the female can extract sperm from the male’s abdomen, forming the mating wheel that I posted at Gallagher Creek a few weeks ago. I did get one closeup of one pair showing the male grasping his mate. Quite a sight, eh? Not much romance among dragonflies, it seems – but then they are called “dragon” flies…

In a large White Oak near the pond, the impressive paper nest of Common Aerial Yellow Jackets (Dolichovespula arenaria) hung among the leaves. This Yellow Jacket species is distinct from the ground-nesting Yellow Jackets of the species Vespula with which I’m more familiar. Bald-faced hornets (Dolichovespula maculatamake these gorgeous exposed nests too. But if you look closely, you’ll see that the inhabitants of this one, flying in and out, definitely have the yellow and black pattern of the Yellow Jacket. Isn’t it amazing how these insects chew wood pulp and shape it into these graceful spheres, filled with perfect hexagons and sturdy enough to survive all kinds of summer weather?

Four Seasons of Varied Recreation

I’ve featured here the natural richness of Lost Lake Nature Park.  But beyond wonderful winter sledding (there’s a warming house too!),  other recreational opportunities are also available. Kayaks for exploring the lake more closely can be rented from the Parks Department by registering at least one week in advance. Check info at this link. Whether you rent or bring your own kayak, there’s an easy-to-use launching platform on the floating dock that also makes kayaking easily accessible by people with disabilities.

Kayak launching is easy from the floating dock.

Consider bringing a lunch to eat at the picnic tables in the shade near the water.  Or fish in the sunshine from the floating dock (with a current license, of course).

The house you see from the parking lot is the home of the caretakers’ family and is a private residence.  But on the lower level is the Nature Center which houses a project workroom and  a display of taxidermy which allows children to see a coyote, skunk, owl, fox, heron and others up close.  (Photo,  copyrighted by CMNTv,  is a screen shot from a YouTube video.)

screen-shot-2016-09-14-at-3-48-50-pmThe Nature Center is not open on a daily basis,  though plans are afoot to expand its use with open houses and children’s day-camping.  The PRC contracts with Dinosaur Hill to host field trips for Rochester school children each year.  This year,  area kindergarteners will be invited.

nature-center-ll

Lost Lake has lots to offer in any season.  The PRC holds a variety of events here, including this fall,  Yoga by the Lake, a Marsh Bird workshop, a Pumpkin Bowling Event and more. See the details in the Fall 2016 newsletter at this link.  I hope to explore the edges of the lake and its wetlands in a kayak before winter comes. Maybe you’d enjoy a picnic after fishing, watching water birds or simply gazing into the golden heart of a waterlily. The short, steep trail through the forest to the top of the sledding hill and down will get your heart pumping in shady woodland landscape. Look for the hole of a local Pileated Woodpecker (Dryocopus pileatus) near the top of the hill. Or come sledding on a snowy Friday night under the lights or on a winter weekend afternoon with the kids. It’s your park so I hope you take time to enjoy it!

THIS WEEK AT BEAR CREEK: The Drama of Drought and Downpours

Western Slope BC August
Goldenrod gilds the Old Fields of Bear Creek in late August.

Blog posts and photos by Cam Mannino

Late summer is always a time of transitions, but this year was particularly dramatic. Bear Creek’s meadows baked for weeks under a blazing sun. The marsh dried completely, stranding an over-heated young  snapper that struggled through a tangled mat of exposed vegetation. Heat finished off blossoms as some wildflowers began to seed earlier than usual. And then in mid-August, the rains came – downpours, thunderstorms and off-and-on showers. You could almost hear the gulping of plants and trees swallowing the moisture through their roots. Snappers again cruised just below the shallow waters of the marsh. Life rallied.  As always, nature just coped and moved on.

Life in the Hot Sun of the Old Fields

The Old Field on the western edge of Bear Creek is quieter now. Mating season has ended (except for the Goldfinches), so birdsong has diminished. But one hot, sticky morning, an Indigo Bunting (Passerina cyanea) threw back his head and let loose his double-phrased song from the highest branch of a tree – a favorite perch for male Buntings.

An Eastern Phoebe (Sayornis phoebe) seemed to be listening to its neighbor as it rested between forays over the baking meadows, trying  to snatch a few unsuspecting insects.

Nearby, an Eastern Phoebe listened as the Indigo Bunting sang.

A juvenile Yellow-bellied Flycatcher (Empidonax flaviventris) posed quietly among the branches of smaller trees on the Western Slope. Expert birder, Ruth Glass, tells me that this little bird probably arrived from Canada or northern Michigan and is now migrating down to the Caribbean. Quite an adventure for a small bird!

Near the moist bottom of the slope one steamy morning, I spotted a lump on a leaf.  A newly metamorphosed Gray Tree Frog (Hyla versicolor) was sleeping on a Common Milkweed (Asclepias syriaca). I’m afraid I woke it with my camera. The U of M’s Bio-kids website says they are “almost always bright green right after metamorphosis [from tadpole stage] and they stay this way for some time before taking on their adult coloration.” These frogs can sleep in the open during the day, using their camouflage to protect themselves; they don’t dehydrate quickly like other frogs. Isn’t it just the best little creature?

While birds foraged from the trees, the insects below braved the blazing sun  to look for their own sustenance. In the grass on the Western Slope, a Common Buckeye butterfly (Junonia coenia) seemed to searching the bottom of grass stems. I’ve read that they sip nectar but often look for fluids in moist earth. Perhaps it was hoping for dew on a hot morning in August.

Higher up on the western path, where the land was drier, beetles probed blossoms looking for food. On the left, a non-native Seven-spotted Ladybug (Coccinella setempunctata) searched diligently for aphids, a favorite food. In fact, these beetles were brought here to combat aphids, but as a result, they’ve outcompeted our native ladybugs whose numbers have declined. On the right, a Soldier Beetle (family Cantharidae) may also be pursuing aphids, though it also eats pollen and nectar. (Hover cursor for captions; click on photo to enlarge.)

In the trees near the top of the Western Slope, a sparrow fluffed its feathers in thin shade. It’s hard to identify juvenile sparrows but with its pink feet and bill, I’m guessing this is a juvenile Field Sparrow who hasn’t yet reached full adult plumage when it will have a more distinct eye ring and a clear breast.

A Field Sparrow has a pink bill and pink feet so I’m guessing this is a juvenile whose breast plumage is still changing.

American Goldfinches mate in August, much later than other birds. On one hot visit,  a female repeatedly rode drying blossoms of Queen Anne’s Lace down to the ground to forage for seeds, perhaps to feed her young –  or her hard-working self! Unlike many seed-eating birds, the Goldfinches don’t switch to bugs when breeding. They are strictly vegetarian.

Nestlings of other birds are transforming into curious fledglings. One afternoon, a young, female Eastern Bluebird (Sialia sialis) perched high in a snag (standing dead tree), her spotted breast only halfway transformed into adult plumage.

Wildflowers felt the impact of the fierce sunlight. A Jewel Weed blossom near the pond dried in the heat, while others took its place in the dappled shade.  And up on the top of the southern hill, the Yellow Coneflowers (Ratibida pinnata) dropped their petals and began the seeding process in the dry heat.

Sturdy Prairie Dock blossoms, looking like little suns themselves,  began to dry out as well as they towered over the wilting Coneflowers.

A female Black Swallowtail hovered just off the sun-drenched Eastern Path, looking restlessly for just the right blossom. Folding its dark wings may help it cope with the sun’s heat.

Patrolling for food, a Ruby Meadowhawk dragonfly rested momentarily  on a leaf, its clear wings shimmering in the hot sunlight.

The northeastern edge of the Old Fields evidently stayed moist despite the  heat and several “wet-footed” plants took full advantage of the bright sunlight.  Joe-Pye (Eutrochium maculatum) spread its dusty pink blooms out across the field instead of appearing as widely distributed single plants as it often does here.

Other native wetland plants fringed the same area.  The trio below includes bright pink Swamp Milkweed (Asclepias incarnata) with its green stems, Joe-Pye with dusty pink blossoms and purple stems and Boneset (Eupatorium perfoliatum) with its white blossoms and leathery leaves.

Below center, the native Bumblebee (genus Bombus) sips nectar from the Swamp Milkweed with its long tongue and on the left, is a closer look at Boneset. Odd name, eh?  Evidently early herbalists noticed the way the stem seemed to rise right through the clinging leaves reminding them of a splint around a bone. So its leaves were wrapped with bandages around broken bones. Native Flowering Spurge (Euphorbia corollata) on the right also thrives here as it does in various spots along the Paint Creek Trail.

Sheltering in the Shade

Near the wood edges, I found mammals and insects enjoying the shade.  Following a shining strand hanging before our eyes, my husband and I discovered a very tiny white spider escaping the bright sunlight on the underside of a leaf. I tried but couldn’t identify it, despite that wonderful design on its abdomen. We wondered if that brown ball was an egg sack. Anyone know this tiny creature’s name?

White spider under leaf
A tiny white spider, unidentified, sought the shade on the underside of a leaf next to what may be an egg sack.

And, as usual, damselflies moved in and out of the shade at the edge of the Oak-Hickory forest. I’m guessing,  based on its bright blue head, striped thorax, and very pale abdomen, that this one may be a female Bluet (genus  Enallagma) or a recently hatched one. But since there are at least 17 species of Bluets in the Midwest, I’m not sure which one this is. Again, I’m open to your ideas.

A White-Tailed Deer (Odocoileus virginianus) sat calmly on the shady site of a dried vernal pool, while her fawn dutifully hurried off into the bushes as I paused for the photo.

And an Eastern Cottontail paused in a shady spot along a trail one hot morning as well.

And Then the Rains Came…

What a relief when heavy rain came to refill the wetlands and ponds at Bear Creek Park! After watching  that young Snapping Turtle (Chelydra serpentina) struggling through vegetation in the dry marsh, it was a relief to see two Snappers feeding and cruising just below the surface in the cooling water provided by the rain.

 

The bright sun and rain caused Common Duckweed (Lemna minor) and Water Meal (genus Wolffia) – often mistaken for heavy algae – to form thicker mats across wetlands around the park. At the Playground Pond, I heard a plop! one afternoon and saw just the head of a Muskrat (Ondatra zibethicus) moving through the juicy green surface. Luckily, its ears close when it enters the water! When swimming, it uses its tail to propel itself with the help of its webbed back feet.

Once the Muskrat dove, I noticed other denizens of the Pond nicely camouflaged in duckweed and water meal as well.  Here are two turtles and a frog on a log decked out in greenery.

Quivering in the duckweed near the boardwalk made me look down to see a whole collection of small Green Frogs (Rana clamitans). Each of those individual spots on the leg  of the frog below is a water meal plant! Ducks do love this plant, by the way.  Sometimes they just dip their bills in and move along, scooping it up.

In the wetland just north of the Playground Pond, a particularly beautiful native plant is blooming in the moist shade, Cardinal Flower or Red Lobelia (Lobelia cardinalis). Last week when I took an out-of-town friend to the park and left my camera at home,  we watched a Ruby-throated Hummingbird (Archilochus colubris) sipping at a tall stalk of this scarlet beauty. I came back for its photo the following day – but no Hummingbird then, I’m sorry to say!

Cardinal flower single
Hummingbirds can be seen feeding at Cardinal Flower in the wetland just north of the playground.

We also spotted two Barn Swallows  perched quietly in nearby trees. No camera again! The next day, they were swooping madly across the meadows, their bills open, enjoying the swarms of insects that had hatched after the rain. One perched for a moment in a snag over the wetland and I got this quick photo of it from below.

As the water rose in the Center Pond, tiny  Painted Turtles (Chrysemys picta) appeared on nearly every log. Here’s a silver-dollar-sized one trundling along as it explores its world like any youngster.

This week, a Green Heron (Butorides virescens) dropped into the bushes at the western edge of the pond. It kept a close eye on the water, when it wasn’t actively preening with its long, extendable neck. Green Herons are expert hunters of both fish and frogs.  I wondered if the absence of July’s huge number of green frogs was attributable to the drought or this multi-colored fisher. (My apologies for the slightly pixelated photos caused by aggressive cropping so we could see it up close.)

Yes, it’s been a hot, sticky and then rainy summer. But we’re all in this together – animals, birds and plants. The natural world provided a gentle reminder that change, even dramatic change, is an inherent part of being alive. Summer may be waning now but the beauty around us isn’t. Surprises await our arrival every day, no matter what the weather.

 P.S.  More Native Beauties Blooming along the Paint Creek Trail!

The trick about blogging during the summer is that so much happens all over the township, all at once!  Keep an eye out for these special native wildflowers blooming for just a short time in the Wet Prairie on the Paint Creek Trail. The shallow water table in this meadow provides a perfect spot for these fire-adapted beauties. The field is dotted with the purple fireworks of Cylindrical Blazing Star (Liatris cylindracea), the striped elegance of Grass of Parnassus (Parnassia glauca) and the delicate, spotted petals of Mountain Mint (Pycnanthemum virginianum). Don’t miss them!

THIS WEEK AT BEAR CREEK: Spring Bursts into Summer – and Delicate Paint Creek Trail Surprises

Geraniums in the woods BC

Well, what a change! Two weeks ago, we had spring flowers, leaf buds and spring courtship as birds sang and showed off in the treetops. And then came the heat and sun, and suddenly, it was early summer with leaves seeming to enlarge by the hour, spring flowers disappearing to be replaced by early summer blooms, more baby birds and the first dragonflies swooping along the paths in front of us.

So let’s explore just a few of the  wildflowers and creatures that shared this change with us.  (Plus some lovely post-prescribed burn surprises along the Paint Creek Trail.)

When it was still spring…

 Late Spring Birds and a Fun Insect

The male Rose-breasted Grosbeak’s  (Pheucticus ludovicianus) long, tuneful song was everywhere in Bear Creek in the last weeks of spring. Now their nests are finished and singing  has to accompany the task of raising young. Both the male and female build that nest and care for the young – a very modern couple! (Click on photos to enlarge; hover cursor for captions.)

Nearby, hopping from limb to limb, two male Yellow Warblers (Setophaga petechia) sang their seductive “Sweet, sweet, I’m a little sweet” song as they chased each other through the small trees at the edge of the woods. I never spotted the female, though she must have been nearby.  She lacks the rusty striping of the male and has a more olive back.

In the fields behind the Playground Pond, a pair of Eastern Towhees (Pipilo erythrophthalmus) were getting acquainted. The male was not singing his “Drink your Tea-a-a-a-” call, so I think the two may have been looking for a nesting sight. I’d never seen the female Towhee before and she’s quite different from the male’s coloring.

Speaking of nesting, I found this large egg under one of the walnut trees near the lane.  If one end hadn’t been missing, it would have been about 2 1/2 inches long.  And there was nothing inside.  I’m wondering if it could be the shell from the egg of a Red-tailed Hawk (Buteo jamaicensis) that I’ve seen off and on near the Center Pond. Cornell Lab describes the Red-tail’s eggs as 2.2 to 2.7 inches long and “white or buffy, blotched or speckled with buff, brown, or purple.”  What do you think?  Any bird egg experts out there?

What could be the hatched egg of a Red-tailed Hawk – but I can’t be sure.

A flash of iridescent green  at my feet signaled the hyper presence of the Six-spotted Tiger Beetle (Cicindela sexguttata) who frequents the forest edge. I imagine it got its name because its larva, developing in a burrow during the summer, springs up out of its hole to catch prey!  A tiny, green, stalking tiger! Cool how their antennae and legs are as green as their bodies.

Late Spring Wildflowers and Leaves

Two weeks ago, the Oak-Hickory forest was filled with big, beautiful Wild Geraniums (Geranium maculatum). These lovely lavender flowers carpet the area near the marsh every year, but this year they were all over the park –  taller, more plentiful and with larger blooms than I’ve ever seen! Perhaps this year’s and last year’s prescribed burns helped.

Wild Geranium
Wild Geranium blossoms bloomed in the mottled spring light of the forest.

Each year I wait for the blossoming of the Flowering Dogwood (Cornus florida) that stands east of the Northern Loop.  I was intrigued to learn that the actual flowers are only the center of these blossoms.  The “petals” are actually bracts, specialized leaves that attract pollinators by glamorizing the cluster of tiny center flowers.  Here are three pictures of the buds, encased in their bracts,  opening as May progresses.

While the Flowering Dogwood buds were opening, the leaves of the Shagbark Hickory(Carya ovata) were just emerging from their amazing buds.

The huge White Oaks (Quercus alba) near Snell Road were producing miniature red leaves  that, two weeks later, were green and stretching out to catch the sunlight.

White Oak leaves are red when they first emerge, but quickly expand and turn green.

Of course, the May Apples (Podophyllum peltatum) were producing their modest white flowers that hang hidden beneath an umbrella of leaves.

Another spring favorite of mine are the little hands of Early Meadow-rue (Thalictrum dioicum) that find spots of sun in the mottled spring light of the woods.

Down at the pond, tiny aquatic buttercups, called White Water Crowfoot  (Ranunculus longirostris) floated in large swirls across the pond.  Once the heat arrived, the flowers disappeared and the brown stems are now making a not-so-lovely brown mat until they sink below the surface.

Heat! And Summer Rushes Forward

Summer Birds and other Creatures

Green Heron (Butorides virescens), one of our summer residents, perched in a snag (standing dead tree) at the Center Pond.  I usually see them fishing at the water’s edge.  According to Cornell Lab, “The Green Heron is one of the world’s few tool-using bird species. It creates fishing lures with bread crusts, insects, earthworms, twigs, feathers, and other objects, dropping them on the surface of the water to entice small fish.”  I will be watching now to see if I can catch one doing that!

Out in Bear Creek Marsh, Ben and an experienced birder, Antonio Xeira, heard the call of a seldom-seen denizen of wetlands, the Sora (Porzana carolina). This waterbird, a member of the Rail family,  with a heavy yellow beak and stock body,  stalks quietly among the cattails, looking for seeds, insects and snails. Its whinnying call is particularly dramatic. Ben and Antonio recognized its other two tone “ker-wee” call at the marsh. Click on its picture here and go halfway down this page for its song and call. I’d never even heard of Sora before!

A delightful sight greeted the Wednesday birders at the Playground Pond last week. A mother Wood Duck (Aix sponsa) was escorting her six ducklings around the pond,  as well as what appeared to be two Hooded Merganser chicks (Lophodytes cucullatus)! Ben surmised that perhaps a Merganser had laid its eggs in the nest hole of the Wood Duck and she ended up hatching them along with her own. Here’s a photo of the adult female with her own chicks and a photo of a Hooded Merganser baby that swam with them.  This Merganser duckling jumps from a tree hole when one day old and swims on its own.  It takes 3 days for the Wood Duck’s ducklings to do the same.

Down at the Center Pond, the “boing-boing” banjo sound of the Green Frog (Lithobates clamitans) creates part of the summer music at Bear Creek.  You can tell this one’s a male because its tympanum, a kind of external ear drum, is larger than its eye. I like this one’s tentative expression.

And the Common White-tail Dragonfly (Plathemis lydia) makes a soft whir-r-r as it soars by, looking for prey. This one’s a female, because the male’s abdomen is white, which accounts for its common name.

Summer Wildflowers

As the heat began, wildflowers started to bloom in the native beds near the parking lot.  One of the loveliest is native Wild Lupine (Lupinus perennis) glowing lavender and white in the warm sunlight.

Nearby was a plant I’d never seen until Ben VanderWeide, our stewardship manager,  made me aware of it.  It has the lovely name of Blue-eyed Grass (Sisyrinchium angustifolium).  To me each tiny blossom resembles a tiny Iris.  It’s called “grass” because it has grass-like leaves and stems with parallel veins that are hard to distinguish from a grass when there aren’t any flowers. The flowers only open fully in full sunlight, so it can be easy to miss early in the morning or on a cloudy day. But isn’t it pretty in the late spring/early summer?

And another early summer favorite is spreading abundantly in the native bed north of the shed.  Canada Anemone’s (Anemone canadensis) lovely white flowers stand gracefully above its deep green foliage .

Sunny Golden Alexanders (Zizia aurea) accompany these other native plants in the wild garden in the driveway center, one of the native beds and across from the Playground Pond.  This one’s hosting a Spittle Bug or Frog Hopper, common names for the super-family of insects called  Cercopoidea.  The adult insects can hop 100 times their length!  The foam is used for protection for the nymph stage of development.  Though the nymph sucks on the plant, it generally doesn’t hurt the plant much.  Most of the liquid is used to create that evidently nasty-tasting froth that deters predators.

Ben and his crew planted some native Prairie Phlox across from the Playground Pond, another area of Bear Creek to be slowly stocked with native plants.

Warm weather brought out the exotic-looking blooms of native Wild Columbine in the bed just north of the shed.  These lovely native wildflowers grew down the side of a hill east of the park when it was a farm back in the 1930s and 40s.

Columbine blossoms in native bed BC
Native Wild Columbine once grew on a hillside east of the park when Bear Creek was a farm in the 1940’s.

And out in the eastern Old Field, lots of native Common Milkweed appeared once the grasses were knocked back by the prescribed burn in March.  No doubt all the nutrients that were released into the soil then, plus the longer growing season caused by the darkened earth, will give it a little boost.  Hope the Monarch Butterflies take note!

And now the Paint Creek Trail surprise…

This spring, Ben VanderWeide, the Township Stewardship Manager, and volunteers did a prescribed burn along the Paint Creek Trail near the parking lot at Gallagher Road.  The purpose, as always, was to stimulate native plants and discourage non-native invasive ones.  Also prescribed fire releases nutrients from last year’s plants back into the soil.

Partly as result of this process, some lovely native plants emerged this year in greater numbers than before the burn.  Look at this lovely photo Ben took of a native Yellow Ladyslipper  orchid (Cypripedium parviflorum)  – and there were lots of them hidden within the burgeoning grass. You can certainly see where this lovely wildflower got its name – a graceful slipper with ribbons attached!

The grass was also shining with Star-grass (Hypoxis hirsuta), a small yellow native that hosts small bees and other pollinators.  It’s lucky there were lots of these shining stars this year because they need other plants to cross pollinate, which of course is assisted by the bees.  Here’s Ben’s photo.

Star-grass Ben's
These bright yellow flowers called Star-grass also shone out of the grass along the PC Trail after the prescribed burn.

Along the tree line near the parking lot at Gallagher, a yellow cloud of Golden Alexanders (Zizia aurea) nodded in the wind.  Ben caught this one up close.

Golden Alexander Ben's

And Ben also noted a Sedge plant  (family Cyperaceae)  with its interesting bloom. As I mentioned two weeks ago, sedges are ancient plants that look something like grasses but are constructed differently. Ancient Egyptians used sedges to make papyrus.

Ben tells me that beautiful native wildflowers like Culver’s Root (Veronicastrum virginicum), Showy Tick-trefoil (Desmodium canadense) and other prairie plants are “sprouting vigorously” along the trail north Gallagher Road – so click on the links to see them and then keep an eye out for them!

So treat yourself.  Hang some binoculars around your neck and look at birds up close – both the year ’round residents and the summer visitors.  Take your time.  Stand near a patch of summer flowers and watch quietly. See what surprises you.  Maybe a bee that turns out to be a harmless hover fly.  Or the shiny glamour of the Six-spotted Tiger Beetle.  Try using your cell phone to take a shot of a single flower you’ve never noticed before and then identify it when you get home.  I promise you’ll relax.  Your breath will slow, you’ll smile a bit more, life will just get more interesting.  Nature comes alive in ways you’d never expect when you give it your undivided attention.  Let us know what you find!

THIS WEEK AT BEAR CREEK: Icy Trails and…Frozen Frogs?

Marsh colors 2winter2015

Blog post and photos by Cam Mannino

The red blush of Red Osier Dogwoods (Cornus sericea) at the edges of Bear Creek’s wetlands provides very welcome color in the brown, gray and white world of a Michigan winter.   The last week of the year, tiny beads of ice fell from the sky for hours,  covering the trails and making for tricky walking.  But at least you’ll never lose your way!  Though the fields are mottled brown and white, the icy trails shine bright white in the landscape.  And deer trails through the thickets are readily apparent, too.

Bare branches and ice make it possible in the winter to really see the southernmost pond in the park near Snell Road.  It’s hidden by surrounding foliage in the summer which probably is why so many warblers and other migrants spent time there in the spring and fall.

Hidden pond at BC
Bear Creek’s southernmost pond near Snell Road is most visible in the winter.

A Muskrat (Ondatra zibethicus) at the marsh had evidently walked across the icy slush either to or from its feeding push-up before the slush turned to ice.  Perhaps you can just make out its frozen footprints in this photo.

A group of hardy American Tree Sparrows (Spizella arborea) repeatedly darted from low bushes down onto the reeds of the marsh.  What could they be finding to eat?  Perhaps seeds, perhaps some frozen insects that mistakenly hatched in the unseasonably warm weather before the ice?  No doubt skills these little birds developed on the tundra during the summer make finding food here seem like fledgling’s play!  Aren’t they nicely camouflaged for this grey and brown time of year?

Mallards (Anas platyrhynchos), of course, found a small area of open water where they could feed.  Most of their compatriots have moved south a bit, but some still probe the depths at the Center Pond and the marsh.

Ice takes so many beautiful forms this time of year.  Forming on the Playground Pond , it looked as though it were embossed on some elegant blue/gray satin.

On grass stems, heavy frost looked granular and spiky.

And doesn’t heavy frost also do a lovely job of tracing the shape of this Queen Anne’s Lace?

Winter is a time of ice and stark shadows so be prepared for more photos of both as the season moves on!

So with all this ice, how do frogs survive the winter?  No, not deep in the mud…

Frog in duckweed
A green frog in summer

It’s true that some frogs, like the ubiquitous Green Frogs (Rana clamitans) of the Center Pond, are spending the winter under the pond ice.

Like the turtles, their metabolism slows drastically to preserve their oxygen during hibernation.  Unlike turtles, though, they can’t bury themselves in the mud because they need to absorb oxygen from the water through their skin.  So they may have a light coating of mud or simply lay inert on the pond bottom waiting for spring. At times, they may even swim slowly through the water.  TadpoleIt can take 2-3 years for a Green Frog tadpole to develop into a frog, so some of their tadpoles are below the ice as well and are reportedly a bit more mobile than the adult frogs.

The striking Leopard Frog, less common in Bear Creek and across the state, also hibernates below the ice.

Frogs that Freeze!

Incredibly, the smallest frogs of early spring actually freeze in the winter and thaw out in the spring!

The Wood Frog (Rana sylvatica), for example, finds a crevice in wood or a rock or simply under leaves, and waits.

Wood frog
A Wood Frog burrows into leaves for the winter, freezes, stops breathing, no heartbeat – and then thaws in the spring!

According to biologist Bernd Heinrich in his book, Winter World, when ice begins to form on any part of its small body, an alarm reaction makes a Wood Frog release adrenaline which signals the glycogen in its liver to turn to glucose which functions like anti-freeze.  “In about fifteen hours, the frog is frozen solid except for the insides of its cells.  Its heart stops.  No more blood flows.  It no longer breathes.  By most definitions, it is dead.” But they thaw in the spring!  As Scientific American describes it, “…when the hibernaculum [the place where an animal hibernates] warms up above freezing, the frog’s frozen portions will thaw, and its heart and lungs resume activity–there really is such a thing as the living dead!”  How amazing is that, eh???  Spring Peepers (Pseudacris crucifer) and Chorus Frogs (genus Pseudacris) can do this as well.

frog and reflections2

These small frogs live mostly on land.  Once they thaw, however, they quickly go to vernal pools to breed.  Because vernal pools are created from snow and ice melt, these frogs do better after a snowy winter.  Their frozen hibernation in shallow places allows them to thaw quickly in the early spring and  mate in these temporary pools, safe from predators like fish or turtles who need permanent ponds.  The tadpoles of these early spring species become frogs much more quickly than the Green Frog’s do, in a matter of weeks or months,  since the vernal pools, like the one near Gunn Road, shrink or disappear as summer comes on.

So nature does it again!  As we tread gingerly along the icy paths of Bear Creek, we can imagine Green Frogs sprawled along the bottom of the pond and tiny spring frogs frozen under leaves or in tree bark waiting for an almost literal rebirth in the spring.  We humans use our complex brains and fire fueled by ancient plants  to survive an icy winter, while  little frogs use massive amounts of homemade antifreeze.  Ice requires a lot of different adaptations for survival and over thousands of years, nature, as always, finds a way.

THIS WEEK AT BEAR CREEK: A Golden Marsh, Frogs Meditate, Squirrels Munch and Mushrooms Arise!

This week we’ll leave the sunny Old Fields and spend more time in the north of the park where there’s more water and shade.  The marsh, like so much of the park, is now full of gold as fall flowers bloom along its margins. The Canada Geese are starting to emerge from the reeds with completely new sets of feathers.  The Snapping Turtle still cruises just beneath the water’s surface while dragonflies hover and soar above it.

In the pond  at the edge of Gunn Road, a few frogs hop between the toes of giant wet-footed trees,  while others sit quietly contemplating the coming season.  Squirrels and chipmunks gather acorns and nibble at colorful mushrooms that  mysteriously appear and disappear in the Oak-Hickory forest.  Let’s watch how the north end of Bear Creek settles gracefully into early fall.

The Marsh – All Golden and Green

The green of the marsh – its reeds, its duckweed-covered water, the backdrop of trees – is suddenly offset by the bright yellow of Nodding Beggar-ticks (Bidens cernua), another lovely native wildflower with a singularly homely name!

Marsh in Sept_edited-1
In September, golden flowers with the strange name of Nodding Beggar-ticks surround the northern marsh.

These sunny flowers surround the water in the marsh, lining the northern dock and the edge of the reeds in the distance. Dr. Ben tells me that they are an annual that “can grow from a seed to a big flowering plant in just a few short months or weeks after the water recedes. They are really well adapted to the changing water levels of wetlands!”  Look at these flower faces which are currently full of bees!

Nodding Beggar-tick are native flowers that nod a bit as they age.

The reeds and flowers are a great backdrop for the Canada Darner dragonfly (Aeshna canadensis), who likes to hover above the water searching for insects,  just as it does above the wildflowers in the Old Fields.

A Canada Darner finds the air above reeds and marsh flowers just as profitable for finding insects as the wildflowers in the Old Fields.

The Common Cat-tails (Typha latifolia) take on all kinds of strange shapes as they produce seed for next year. The male part at the top has fertilized the brown fuzzy female part below to produce seeds.  And cat-tails also grow by rhizomes, or underground stems.

Out in the water are the usual inhabitants.  If you come after a rain has cleared some of the surface plant life, you might see the ridged back (or carapace) of a Snapping Turtle (Chelydra serpentina).  Its head  emerges several inches ahead of its body as it cruises leisurely across the marsh, stopping to dip down and feed on submerged vegetation.

Of course, if you come on a hot, sunny afternoon when the duckweed and other surface plants crowd the marsh surface, you’ll have to look for  the trail of  two slowly moving blobs of green.

Snapper in the marsh2
On a sunny day with the surface plants thick and rich, look for the Snapper’s water trails to find the slowly moving green blobs of its shell and head.

If the sun is warm on a cool fall morning, you might see a small Painted Turtle (Chrysemys picta) sunning itself, all four legs, head and tail extended to soak up maximum warmth.

Baby turtle sunning
A small Painted Turtle suns on a log, all four legs stretched out to catch the sun’s warmth.

Some of the Canada Geese (Branta canadensis ) have now finished their molt.  This one seemed to be waiting for other family members to emerge from the reeds.  When they do, they’ll get some practice flying with their completely new feathers, wheeling about the sky and calling noisily.

Canada Goose after molting
A Canada Goose seems to be waiting on the edge of the reeds for the rest of its family group to finish their complete molt.

I’ve noticed this plant in the marsh for a while and finally learned its name.  Ben tells me that it’s Nodding Smartweed or Willow-weed (Persicaria lapathifolia).  It’s common in moist, disturbed ground.  I quite like its graceful droop!

The Pond at the North End:  Mighty Trees, Their Munched Acorns and Small Frogs

If you wander away from the marsh toward Gunn Road, you’ll end up at another much quieter pond.  It’s the one in which so many Wood Frogs (Rana sylvatica) were courting in the spring. Some of these frogs breed more than once which might explain seeing two tiny Wood Frogs near the pond at this time to year. Wood Frogs can vary their skin color from brown to green/gray but they are always in or near the trees (as their name implies) and sport a dark eye mask.

Nearby, as the sun dipped low, a male Green Frog (Rana clamitans) sat quietly on the end of a log, staring steadily into the distance.  It’s rare for me to see one so still and silent.

In the late afternoon, a male Green Frog stares quietly into the distance from a log in the pond near Gunn Road.

An Orb Weaver Spider (family Araneidae) had rather daringly hung its web out over the water, attaching it to four different trees quite a distance away.  It looks as though it managed to snag a moth.

Some creature had dug a fairly large hole, with accompanying small ones, at the roots of a gigantic Bur Oak (Quercus macrocarpa). An Eastern Chipmunk (Tamias striatus) perhaps?   Here you can see one hole beneath a Bur Oak leaf and the remainder of the tree’s acorn with its bristly cap laying nearby.  Bur Oaks, a member of the White Oak family,  don’t produce large acorn crops every year.  Instead, they produce huge numbers of acorns some years in the hope that the squirrels and blue jays will not be able to eat them all and a few will survive to propagate new trees.

Here’s a clearer look at the acorns from a Bur Oak that’s just south of the shed near Snell Road.

But the one at the north end is very tall – and incredibly straight – with its crown so far up that you can’t see its acorns even with binoculars!  Or at least, I couldn’t.

Eastern Chipmunks (Tamias striatus) are certainly dashing about the park collecting nuts and seeds to put in the storage chambers of their burrows.  This one started filling its pouch near the Center Pond in a previous fall.

The Oak-Hickory Forest and its Mysterious Mushrooms

Dappled sunlight in the woods

The Oak-Hickory forest is blooming – with colorful mushrooms! I learned this week that there are fungi in the earth beneath those trees year ’round. Right now we can see parts of those fungi because they’re making spores above ground in what we commonly call “mushrooms.”

Some fungi break down dead materials to obtain nutrients.  Other fungi form relationships with living plants, including trees,  which generally are mutually beneficial.  This symbiotic association between a fungus and a living plant is called a mycorrhiza.  Mycorrhizal fungi feed on sugars from tree roots and trees in turn can get more minerals and water from the soil through their fungal partner.  According to BBC Earth, some scientists have shown that trees use this system to share nutrients with other trees, including their own saplings, in what some scientists refer to as the “wood wide web!” This web may include both the fungal network and tree roots that are actually grafted together.  I love this idea. Of course,  problems can spread through this web too ( just like our internet!) which is why we published the blog on preventing the spread of Oak Wilt.

Having missed the Parks mushroom workshop last weekend, I can’t identify most of the mushrooms I’ve seen lately. (Drat!)  They look so other-worldly and fascinating. Unless accompanied by a real expert who can make an absolute identification, though, please don’t try to eat them!  Wild mushrooms are notoriously difficult to identify and many are toxic to humans. And in any case, it’s always best to leave the park just the way you found it so we can all enjoy its beauty and surprises.

This amazing mushroom, which may or may not be a Sulfur Shelf mushroom, glowed in the dappled light of the woods.

These unidentified mushrooms may have been eaten by some small woodland animal, perhaps the American Red Squirrel.

One of the likely consumers of mushrooms in the forest is the  American Red Squirrel (Tamiasciurus hudsonicus) which can safely eat some that are toxic to humans.

Speaking of “fruits,”  the Pasture Rose (Rosa carolina),  seen in early summer on southern end of the western forest path, has left a lovely fruit, known as a “rose hip.”

Bear Creek offers so much variety – the buzz and sway of the meadows, the shady walnut lane, the small ponds, the big, wild marsh and the dappled light of the woods.  A niche for every mood.  Hope you find the time to sample  some of them soon!

THIS WEEK AT BEAR CREEK: Story-telling Wildflowers, Solo Fledglings and the Usual Odds ‘n’ Ends

First week of July, the launch point for what I think of as High Summer.

Blog post and photos  by Cam Mannino

Though it’s gray and rainy as I write (again!), I’m still anticipating the dry heat of the heart of the season when the Old Fields of Bear Creek are sprinkled with color,  grasses and tall flowers bend and sway in the wind, big nectar-sipping butterflies balance on blossoms and swallows swoop and dive overhead.  Hope springs eternal that we will see more days like the 4th of July weekend, eh?

History as Told by Wildflowers

Botanists use the term “Old Fields” for the largely treeless expanses of Bear Creek when you enter from Snell Road and west of the playground pond.  I love the term because it implies a history and for me, the wildflowers express that history in different ways. Compared to native grasslands, savannas, or prairie, Old Fields typically have an abundance of non-native, often agricultural, plants and a few scattered native plants that recolonized after farming or grazing stopped.

It only makes sense to begin with Michigan’s Native Americans.  Meet Indian Hemp (Apocynum cannabinum).  During its growing season, all parts of this plant are toxic so you and that dog on your leash should leave it alone (in case either of you were tempted to eat it!) What’s historically interesting is that native people figured out that in the fall, when the toxins drained down into the roots, this plant could be harvested usefully. According to Wikipedia, Indian Hemp was  “used as a source of fiber by Native Americans to make hunting nets, fishing lines, clothing, and twine.”   Hemp is still used in similar products today.  I love its dark red stems and tiny white flowers. You’ll find it along the north side of the path that curves down around the vernal pond below the high seating area on the south side of the Park.

indian hemp 1
Native Indian Hemp had many uses for the Indians who harvested it in the fall when the toxins in the plant had drained down into its roots.

When settlers arrived in Michigan, the dry, sunny, sandy soil of these areas of Bear Creek were prairie – tall grasses, a few native trees and native flowering plants.  Those settlers probably saw our native Black-eyed Susan  (Rudbeckia hirta) when they arrived.  And they are still here,  currently growing in profusion up near the benches on the hill at the south end of the park.

Edit:  Ben tells me that many plants in the Aster family (Asteraceae), to which Black-eyed Susans belong, have two different sets of flowers – the big petals are actually individual ray flowers with reproductive parts at the base, and the black center is made of individual disc flowers (the outer ring of disc flowers are flowering in this picture).  Click here for a basic explanation, or here for a more technical explanation. So every apparent “petal,” small and large,  is actually a separate flower, producing its own seed!  Quite an amazing amount of seed production in what looks like one big flower!

black eyed susan
The bright eyes of the native Black-eyed Susan would have been here to greet early settlers.

Another beloved native, Butterfly Milkweed (Asclepias tuberosa) could have greeted those settlers, just as today its hot pink buds burst into orange blossoms in the native bed and here and there in the field west of the Center Pond.  True to its name, last Sunday it hosted a Meadow Fritillary (Boloria bellona).

According to Wikipedia, after the Civil War,  a U.S. farmer and agriculturalist, Timothy Hanson,  is said to have introduced a European grass as a source of  hay and cattle fodder. Today it’s still here and plentiful and is probably named in Mr. Hanson’s honor; it’s called Timothy (Phleum pratense). It’s a beautiful grass but as a European import, it’s less useful to our native wildlife.  Here it is  in flowering mode with showy red anthers (pollen making organs) at Bear Creek at the top of the hill near the seating area again. Like all grasses, Timothy is wind-pollinated and throws copious amounts of pollen to the wind, hoping that a few pollen grains will land on receptive stigmas of another Timothy plant (stigmas are part of the “female” reproductive structures in plants). Since grasses and other wind-pollinated plants don’t need to advertise to pollinators like insects, birds, or bats, their flowers are not very showy, and sometimes plain hard to see!

Non-native Timothy, a European grass brought here to feed sheep and cattle.

After two hot days over the weekend, it had finished flowering for the season, a blessing for folks with spring allergies!

Timothy after seeding
Timothy grass finished flowering by this Monday after a warm weekend.

Timothy and other non-native grasses took the place of tall prairie grasses like Big Blue Stem which is slowly returning to Bear Creek after prescribed burns.  Many of our ground-nesting birds like Pheasants, Meadowlarks and Northern Bobwhites prefer these tall native grasses and losing them, as you’ll hear from me often, reduces the biodiversity we were blessed with here. This fall photo at Seven Ponds Nature Center will give you a feel for the height of this tall native prairie grass that  once flourished in Bear Creek and now is making a comeback .

Big blue stem

Farmers were still farming here in the 1940’s, of course,  and like the settlers, they needed pasture, hay and silage for their animals.  These days Butterfly Milkweed has to contend with the Birdsfoot Trefoil (Lotus corniculatus),a plant from Eurasia and Northern Africa,  which farmers probably seeded while creating pasture for sheep and cattle.  It’s a lovely plant up close, though this particular specimen could be a cultivar (a garden version) that snuck in among the others which aren’t quite as regular and glamorous.

But look what happened this year to Butterfly Milkweed in the meadow west of the Center Pond.  You can barely see the orange of the Butterfly Milkweed among the yellow of Birdsfoot Trefoil!

Next week, along with this week’s discoveries, I hope to explore the historical “roots” (as it were) of other native and non-native species in the shady areas of Bear Creek.  I never knew how much history was blooming right under  my nose!

Fledglings and Old Friends

If you walk along the lane of Walnuts (Julgans nigra) at the center of Bear Creek early in the morning or late afternoon, you’re likely to see some very small, a bit rough-around-the-edges fledglings off on their first solo explorations, no adult nearby.  These young birds are notoriously hard to identify because their plumage is often quite different from their parent.  For example, I’m 99% sure this is a baby Bluebird (Sialia sialis) we saw on Sunday, because of its white eye ring, brown speckled breast, and most importantly, the blue feathers in its wing and tail – and also because it’s smaller, curious and has a not-quite-finished look.

A fledgling Bluebird (I think) surveys a walnut tree along the center lane.

But I could be wrong – so feel free to correct me!

Here’s another fledgling high in a walnut tree.  Warblers are particularly hard to identify as fledglings,  but I’m going with a fledgling Yellow Warbler (Setophaga petechia).

fledgling yellow warbler?

Remember the adult version from an early spring post?

Yellow Warbler posted earlier this spring.

One of our faithful birds, here summer and winter, was also hopping around the walnut trunks searching for bugs or places to store big, fat seeds.  Here’s the agile White-Breasted Nuthatch (Sitta carolinensis) in an unusually upright position:

More often, you’ll see a Nuthatch foraging upside down like this:

And a summer visitor was farther out in the small trees just east of the Walnut lane, the russet and black Orchard Oriole (Icterus spurius) with his beautiful yellow-olive mate (not pictured).

The male Orchard Oriole flitted through the small trees with his mate (not pictured) who is yellow and olive green.

Another faithful resident, the American Robin (Turdus migratorius) is beginning a second brood for the year so look for a female, like this one in a red oak this week,  sitting in her nest with just her head and tail showing.

Robins are beginning their second broods of the season.

Those Odds ‘n’ Ends

In the north marsh, Reg spotted what looked like an upside-down Snapping Turtle  ((Chelydra serpentina), its light lower shell (plastron) exposed and its legs flopping in the air.  It was very far away and we puzzled over the sight through binoculars, until suddenly the turtle righted itself and we saw two turtles turn and swim away from each other!  Apparently we saw mating Snappers which breed between April and November.  Since the distant white blob didn’t make much of a photo, here’s a reminder of the beak-nosed appearance of this prehistoric reptile.

snapper head on_2
We saw two of these amazing Snappers mating in the marsh about a week ago.

I must admit that the Center Pond is at its most homely right now.  I hope you saw the White Water Crowfoot (Ranunculus aquatilis), an aquatic buttercup, in bloom earlier, because now it’s left mats of brown strings across the surface.  But despite that, we laughed at seeing 14 young Green Frogs (Lithobates clamitans), sitting at attention on that brown surface all over the pond, each in their own separate little territory, probably enjoying the sunlight.  The bright yellow belly and the tympanum (a frog’s eardrum) on the cheek  that’s bigger than the eye tells you this is a young male on a log near the deck.

The tympanum (a frog’s eardrum) that’s larger than its eye and a bright yellow belly means this is a young male Green Frog.

I marvel at the semi-precious stone appearance of the Amber Snail (genus Succineida) who lives in moist areas – like this one, found on a dewy leaf near the playground pond.

The appropriately-named Amber Snail loves moisture!

Coming Attractions:

July is the month for a beloved non-native wildflower, Queen Anne’s Lace (Daucus carota) and the first blooms and buds are beginning to show among all that tall grass.  I’m glad this is one of the non-native plants that can co-exist with our native ones!

History under our feet, fledglings surveying the park from high in the walnut trees, and all the other pleasures of summer in Bear Creek await you – on the next sunny, breezy summer day that we all hope is just over the horizon!

This Week at Bear Creek: Summer’s Door Opens – Baby Animals and Lots More Butterflies

Blog post and photos by Cam Mannino
Blog post and photos by Cam Mannino

June is the start of summer for me.  (I don’t wait for the equinox.) Courtship is complete and birds are nesting.  Young animals born in the early weeks of spring are old enough to begin exploring on their own.  And butterflies either arrive from far-flung locales or begin to emerge from their chrysalises or from under the bark in which they have overwintered.  Tadpoles wriggle in every pond and spring green slowly turns deeper and more lush.  Let’s open the door to the summer months at Bear Creek.


Raccoon peaking from White Oak
Raccoon peeking out from a tall tree in the western woods.

The Raccoon’s (Procyon lotor) offspring, known as “kits,”   are evidently living at a new address.  My reliable sources tell me the hole in the tree on the western side of the woods doesn’t show much activity.  However, ’tis the season for raccoon kits so they are out there somewhere!  Here’s a curious raccoon kit peeking out at me two years ago from the big hole while his siblings entertained themselves by climbing up inside the tree and sliding back down.

Raccoons are extremely clever animals.  In captivity, they can quickly learn how to open complicated latches and then “remember the solution to the task for up to three years.” (Wikipedia)  To see raccoons in the woods, it’s essential to be as quiet as possible because they have outstanding hearing.  They can hear earthworms moving underground!  With their hyper-sensitive front paws, they eat a wide range of foods – bird eggs, amphibians, fish, insects, human garbage (unfortunately) and in the fall before hibernation, acorns and walnuts.  Last year we saw an albino raccoon in the big hole so keep an eye out!

The Eastern Chipmunks (Tamias striatus) will have given birth to their first litter of four or five babies who spent about 6 weeks in the burrow under ground and now hang out with their parents for two weeks before heading off on their own.

baby chipmunk
Baby chipmunks spend 6 weeks in the burrow, two weeks outside with adults and then they’re on their own.

The adults will have another litter in the early autumn.  Like rabbits, chipmunks are an important source of food for many animals, hence the need for many offspring.  They themselves will eat bird’s eggs, small frogs, insects, worms, as well as all kinds of nuts and seeds.  We’ll talk more about them in the fall as they stuff their cheek pouches to prepare for hibernation.

adult chipmunk
Chipmunks have two litters, spring and fall, of four or five offspring each time.

Ben’s seen two wonderful birds in the park in the last few weeks, residents that will stay all summer.

catbird
The catbird does “miaow” but he also sings a complicated song composed of mimicked bits of other birdsong.

Male Gray Catbirds (Dumetella carolinensis) offer beginning “birders”  the easiest call to remember; they actually make a very distinctive “miaou” just like a small cat when courting or feeling threatened by predators.  Once you hear the mew, look in a nearby thicket for a sleek gray bird with a black cap, because catbirds generally fly low and perch in shrubs or small trees.  While establishing his territory, however, the male perches at the top of a small tree or bush (the proverbial “catbird seat”) and sings a fabulous, complicated song, stringing together mimicked song fragments of other birds’ songs. To me, it always sounds like an overheard conversation:  “No, really?” “Yes, it’s true!”  “Well, I never!”  Click on the Typical Voice link about halfway down the page on the left at this link and give it a listen.

The other beautiful bird that Ben saw is the Tree Swallow (Tachycineta bicolor).  One of the great avian acrobats, these iridescent blue and black swallows swoop and glide over the meadows and marshes, literally swallowing insects on the fly.

Swallow flying
Tree swallows scoop up insects on the fly as they soar above the fields and marsh.

Tree swallows make nests in natural cavities or woodpecker holes in dead trees or human-provided nesting boxes, which become important as we humans cut down dead trees.  Interestingly, they line their nests with the feathers of other birds, i.e.,  they literally “feather their nests!”  Swallows compete for feathers and may snitch from other swallows or try to catch one in mid-air if it’s dropped by a careless swallow.

A rare opportunity to see 2 tree swallows at rest on a nesting box at 7 Ponds Nature Center.

And Here Come the Butterflies! 

The number of  butterflies fluttering across the old farm field next to the eastern path increases all the time. The gorgeous Yellow Swallowtail (Papilio glaucus), also known as the Eastern Tiger Swallowtail, was in the US in 1587 when it was the first drawn by a member of Sir Walter Raleigh’s third expedition to Virginia.  You can see why it caught his eye.  The male is always yellow with four tiger stripes.

The male swallowtail is always yellow with 4 black tiger stripes.

The females look similar but have showy iridescent blue spots at the bottom of their hindwings. Look carefully and you’ll see them from below here.

female swallowtail
Look carefully and you’ll see the showy blue spots at the bottom of the female Yellow Swallowtail’s hindwing.

Or the female can take a black form (or morph) and then you can really see the blue spots.

black morph female swallowtail
The female Yellow Swallowtail sometimes takes on a black form, or morph.

I always thought these were Black Swallowtails, but they are a completely different butterfly!

This immigrant from the southern US is the Red Admiral (Vanessa atalanta), a medium-sized butterfly with wonderfully bright colors.

Red Admiral2
The Red Admiral has striking colors on the dorsal (upper) side of his wings.

But  look how well it camouflages itself when it settles down to eat!

red admiral camouflage
The underside (ventral) of the Red Admiral’s wings provides excellent camouflage when it lights to eat or rest.

Two related but smaller, more modest butterflies have also just emerged from their chrysalises.  The Cabbage White (Pieris rapae) does love cabbage but also loves purple, blue and yellow flowers.  The males have one black spot on their wings and the females have two.  Here’s a group of males sipping at a moist spot on the path behind the center pond in order to replace the nutrients they pass to the female when they mate.

 COMING ATTRACTIONS

– The tadpoles of the Green Frog (Lithobates clamitans) are now roiling the usually calm waters of the pond next to the playground and other ponds and pools in the park.

A few adult Green Frogs are around, but wait for the chorus to begin!  They sound like a whole bunch of individual banjo strings being plucked at once!

The Green Frog’s voice sounds like a plucked banjo string.

– The female Canada Geese (Branta canadensis) are nesting comfortably, many of them on top of old muskrat “push-ups” which muskrats build from mud and vegetation to protect themselves and their young.  (By building push-ups and eating vegetation, muskrats keep open water for aquatic birds.) The two species seem to co-exist quite nicely.    So, goslings should be making an appearance any day now, if they haven’t already!
