Bear Creek Nature Park: Life-or-Death Drama…but Always the Persistence of Life

View through the woods to a wetland at Bear Creek

Bear Creek Nature Park is the Oakland Township Park I know best. I’ve walked there with my husband Reg for almost thirty years and brought some sort of camera with me for the last thirteen of them. As the winter ebbs each year, we watch for the appearance of the first narrow leaves of Spring Beauty or Blood Root under certain trees. Each May, we check out a huge hole in a particular oak, hoping for a glimpse of this year’s raccoon kits scrambling up and down within in the trunk. My husband has an eagle eye for the slowly moving hulk of snapping turtles gliding across the surface of the marsh and we both listen each summer for the banjo-like strum of the Green Frog’s song at the Center Pond.

But after all these years, we can still be fascinated by something we’ve never seen before, as you’ll see in the life-or-death drama of two determined foes fighting for life on the western slope last week. It’s a fresh experience to watch a trio of Eastern Bluebird fledglings sorting out their relationships in the Eastern Meadow. Amid all the comforts of the turning seasons with their eternal cycles of emerging, blossoming and subsiding, we can still be amazed by the persistence of life. Let me show you what I mean.

High Drama on the Western Slope

The Western Slope at Bear Creek Nature Park, August 2019

My husband and I headed for the western slope one perfect summer day and came upon two small creatures in a life-or-death contest. My husband spotted a large, yellowish/white  caterpillar with five spiky, black  hairs chewing avidly on a Box Elder leaf (Acer negundo). I learned later from Dr. Gary Parsons, Collection Manager and Bug House Director at Michigan State University’s Etymology Department, that it was the larva of an American Dagger Moth (Acronicta americana). When we stopped to look more closely, we saw a large, exotic-looking insect hovering nearby. Oh boy, I recognized this determined female.

It was an Ichneumon Wasp (family Ichneumonidae), a creature that preys on caterpillars in order to plant its eggs in or on them. When the eggs hatch, the unfortunate victim provides a plentiful source of food for the Ichneumon Wasp’s young!

This female kept her long abdomen with its ovipositor curled upward like a scorpion as she maneuvered near her target. The caterpillar clearly sensed the danger of her presence because it began to rear back its head along its body, thrashing forward each time the insect approached. The wasp first hid under a nearby leaf and then leapt forth, for all the world like a silent movie villain!

The Ichneumon Wasp appears from behind a leaf as the caterpillar begins to thrash to keep it off.

The battle went on and on in the bright sunlight. The wasp repeatedly attempted to gain  purchase on the caterpillar, but its bristled body and its constant thrashing made depositing the wasp’s eggs extremely difficult.

The Ichneumon Wasp tries to land on the caterpillar but the caterpillars bristles and its thrashing are quite a defense!

They were worthy opponents. We waited a long time but the battle continued to rage – the caterpillar eating the leaf between attacks to keep its energy up and the wasp trying desperately to deposit its eggs on a nourishing food source. Eventually, we left them both to their fate and walked on into the morning.

It was a peaceful change of scene to see male and female Monarch butterflies (Danaus plexippus) settling on plants nearby. I hope they mated and laid eggs earlier since they were landing on Common Milkweed (Asclepia syriaca) that weren’t young and tender, but too dry and tough to provide much nutrition for their offspring. Perhaps they were some of the first Monarchs to start migrating south to Mexico. [Click on photos to enlarge; hover cursor for captions.]

In early August, we saw a female Monarch fluttering among fresh Butterfly Milkweed (Asclepias tuberosa) in the meadow west of the Center Pond. Monarch caterpillars specialize; they only eat milkweed leaves. Perhaps this one’s young are currently nibbling their way along the leaves of this plant, intending to molt, pupate and emerge before the migration.

On August 1, we spotted a female Monarch fluttering among Butterfly Milkweed, perhaps eating, perhaps stopping to lay her eggs.  

Just a short way along the Western Slope trail, a slightly worn Viceroy Butterfly (Limenitis archippus) settled on Queen Anne’s Lace. Viceroys look very much like Monarchs and recent research indicates that both species use their color to advertise that they are unpalatable to predators. However they can be distinguished from Monarchs by the thin, black lines across the veins of the hind wings. Often, too, they tend to flutter more frequently than Monarchs which beat their wings quickly and then coast for a few moments in flight.

The black lines on its hind wings distinguish the  Viceroy Butterfly  from the Monarch.

Viceroys have another defense against predators like the Ichneumon Wasp. Their caterpillars look like bird droppings! Here’s a photo of one shared by a photographer who uses the name jdfish1 at inaturalist.org. What a strategy this butterfly evolved for protecting its young!

The Viceroy’s caterpillar looks so much like a bird dropping that predators may not even notice it.

On to the Pond:  A Stealthy Fisher and I Share Strategies

As I turned down the path that leads to the Center Pond, I was confronted by a wriggling, bristly caterpillar who appeared to be suspended in mid-air right in front of me. The Hickory Tussock Moth (Lophocampa caryae), like the Dagger Moth caterpillar, is covered with bristly hairs that can cause a skin rash if you pick either of them up. Since it pupates in leaf litter after eating on leaves, it was wriggling out an almost invisible string in order to carefully lower itself to the ground. It didn’t look fully grown to me because it hadn’t developed the long black hairs front and back of later instars. I wished it well and passed on.

But after a few steps, I stopped again. A young Green Heron (Butorides virescens) sat preening in a branch near the dock.

A juvenile Green Heron preening in the sunlight.

I love watching these birds fish, so I approached very cautiously, repeatedly taking a few slow-motion steps each time the heron looked out toward the pond and then pausing when it looked even slightly in my direction. After checking out its feathers, it flew down to stand in the water, stretching out its long neck. It didn’t stay there long; Green Herons often prefer to hunt from a perch rather than wade like the Great Blue Herons, for example.

I continued to stealthily approach each time the heron’s focus turned out toward the pond.  And suddenly, it flew to the dock and began to hunt in earnest. I As I watched it verrrry sloooowly step down to the edge of the dock and stretch out its neck to search for prey, a huge smile spread across my face. I almost laughed aloud. I thought, “You and I, Green Heron, have developed the same strategy, except I want a photo and you want a meal!”

It didn’t score a meal that time. It gave up and flew to the other side of the pond. Here’s what it was probably looking for, but couldn’t quite reach – a Green Frog (Rana clamitans) immersed in duckweed, who lived to mate another day.

When I reached the deck, a family of three small Wood Ducks (Aix sponsa) with an adult female were feeding off the bright green Common Duckweed (Lemna minor) on the far side of the pond. Three other young wood ducks cruised around by themselves, far from the others.

I’d seen this same grouping at the bird walk a couple of days earlier. This time though, the female spotted me in the distance and disappeared into the vines at the far edge of the pond.   When she returned, she appeared to have summoned the male who’d been hiding  because he clearly was molting. His gorgeous iridescent green crest and curvy “duck tail” were being replaced by more sedate non-breeding plumage. He and the female quickly stood guard over their family group as if to put me on notice!

The male Wood Duck came out of the vines despite being in molt when summoned by the female to defend the young from that strange person with the camera on the deck.

The other three ducklings came a bit closer to the others, but again seemed to be happy on their own. I wondered if they were from her first brood, since Wood Ducks can breed twice in a summer, though the minimum number in a Wood Duck clutch is usually six. So maybe she just had three slightly more independent offspring and three who needed more protection? No way of knowing.

The male Wood Duck eventually decided I was not a threat and disappeared back into the tangle of vines to work a bit more on his molting process.

My husband and I watched an Eastern Wood-pewee  (Contopus virens) sally forth from the shrubbery to hawk for insects. But as soon as it returned to the dead vines at the pond edge, it almost disappeared from view. See how quickly you can spot it here:

A camouflaged Wood-Pewee disappears into the landscape while foraging at the pond.

As I left the pond, walking along the eastern boardwalk, I heard the “miaou” call of a Gray Catbird (Dumetella carolinensis). One of the birders had pointed out a catbird there earlier in the week and I’d taken a quick photo. But I told the others that I’d always wanted a good photo of the rusty undertail coverts of these birds and I’d never gotten one. Well, two days later, I heard the “miaou”  again, and there it was obliging me  by showing the part of its anatomy that I’d read about but never caught in a photo.

In the meadow west of the Center Pond, the Wednesday birding group also spotted a male Indigo Bunting (Passerina cyanea) dropping down into the grass to feed and then quickly rising again to the nearest branch. I got a quick photo then to share with you, but didn’t see the bird again during the week. Keep an eye out when you’re there. He’s a beautiful eye-full, even when looking a bit bedraggled either from parenting duties or perhaps the beginning of his molt.

Out on Bear Marsh with Snappers!

Bear Creek Marsh on a breezy summer day

In the woods on the way to the marsh, a movement at our feet caught our attention. A tiny American Toad (Anaxyrus americanus) about 3/4 of an inch long, hopped onto some leaves and froze, hoping perhaps to blend into the background and escape notice; camouflage is a basic survival strategy for toads. Though they breed in shallow water,  they spend most of their time on land. I love this little toad’s chubby legs. Small as he is, he’s off into the larger world to feed and if lucky enough to survive, produce another generation of toads.

A tiny American Toad. Juveniles like this are more active during the day than adult toads.

Along the way, some small white mushrooms stood tall along a seam in a log. Crown-tipped Coral mushrooms (Clavicorona pyxidata) are aptly named. They do resemble undersea corals and their tips are recessed and surrounded by little points. They grow only on dead wood, especially hardwood that has lost its bark. So they are helping to recycle the forest for us and creating this odd, but lovely life form in the process.

This Crown-tipped Coral mushroom is probably at bit past its prime since it’s no longer white. Or it may just not have gotten enough sunlight.

A couple of striking insects also appeared as we passed through the wood toward the marsh. A Northern Pearly Eye butterfly (Enodia anthedon) landed in a bare spot on the trail, sunlight shining through its wings. This butterfly doesn’t feed on flowers, but on tree sap, rotting fruit, decaying vegetation, even carrion – transforming death back into life. The life cycle of butterflies is full of amazing transformations, so why not one more?

The Northern Pearly Eye frequents shady wooded areas unlike many other butterflies.

Dr. Gary Parsons of MSU also helped me identify this cartoonishly cute, metallic native bee near the marsh as being from the family Halictidae. They are commonly called Sweat Bees, the ones that are attracted to your perspiration. But this tiny one was sipping from the drying blossoms of a native wildflower called Jumpseed  (Persicaria virginiana), so called because according to Michigan Flora,  if the plant is disturbed, it can propel mature seed about 9 feet, a nifty means of dispersal!

A native, solitary bee from the family Halictidae sips nectar from native Jumpseed.

At  least six Common Snapping Turtles (Chelydra serpentina) moved slowly through the water at Bear Creek Marsh, their shells looking like moving clumps of mud. Snappers are generally shy and harmless except when bothered on land. Their plastron (the lower shell) is  small, leaving parts of its body exposed and vulnerable. They can’t completely disappear inside their shell and be safe like many turtles. So on land, their only protection is flinging out their very long necks and biting. Snappers clean our lakes and marshes of bacteria much like vultures clean our land, by consuming underwater carrion, but unlike vultures they also forage for live prey and aquatic vegetation.

The edge of the dock at the northern entrance to the marsh is blooming with Arrowhead (Sagittaria latifolia), a lovely aquatic plant that produces white flowers sprouting from both sides of a stalk or “raceme”- and the large, vivid arrow-shaped leaves are almost more beautiful than the flowers! Dragonflies cling to them like bright baubles. What a sight on a summer morning!

The Eastern Meadow: Young Birds Out on Their Own..Sort Of

The Canada Goldenrod (Solidago canadensis) is just getting ready to turn the meadow gold. A male American Goldfinch (Spinus tristus) stood on a thistle and happily tore off some of the Goldenrod buds, possibly to feed either his mate or young. Goldfinches don’t start breeding until late summer when the thistles provide down for nests and seeds for growing broods.

Once he looked up and saw my camera, he gave me a wary glance but went right back to foraging.

Joe Pye (Eutrochium maculatum) blooms in soft patches of bright pink blossoms with purple stems along the eastern trail. There’s just enough moisture to keep their “feet wet,” and the Bumblebees (genus Bombus) hum contentedly as they search for nectar from both the buds and the shaggy, open blooms.

A Common Wood Nymph (Ceryonis pegala) butterfly bobbed along pausing periodically in the deep grass. I mistook it at first for the Little Wood Satyr because they look similar. But the Wood Nymph is almost twice as big and frequents grassy fields while Wood Satyrs prefer shady woods or wood edges. The Wood Nymph also appears a bit later in the summer than the Wood Satyr.  Glad my source, Butterflies of Michigan by Jaret C. Daniels set me straight!

The Common Wood Nymph likes sunshine and is twice the size of the Little Wood Satyr.

When I first saw three fledgling Eastern Bluebirds (Sialia sialis) near the top of the trail, they were all sitting on a sign together. But as I approached,  two of them rose into the air and began mock fighting, banging into each other, flying away, settling for a moment, and then mock fighting again. They were too quick for me to snap a photo. Meanwhile the third little bluebird went off on its own, first looking about and then pecking quietly in the grass as it had no doubt seen its parents do.

A solitary little Bluebird fledgling left its siblings to forage in the grass.

Eventually it flew to a bare tree far off in the field and calmly surveyed the whole field. The blue on its wing tips and tail feathers was much more apparent in the full morning sunlight.

The blue tail feathers of the solitary fledgling Bluebird shone in the light.

The two more social siblings finally settled next to each other on the edge of a sign. After all that mock fighting, they snuggled up against each other – though I wonder if an ornithologist would tell me that the play fighting was dominance behavior and the positioning of the one fledgling’s head over the neck of the other meant that they had settled the pecking order between them.

Two bluebird fledglings settle together after play fighting over the field.

I later spotted two fledgling Bluebirds next to a male adult in a tree along the Walnut Lane. I wondered if the two fledglings were the scrappy pair who rested on the sign. All three seemed to be focused on the field. Maybe they were looking for the solitary fledgling who preferred to be off on its own. It was fun to imagine family dynamics among bluebirds.

What I think was a small Amber Snail (family Succinea) left a shining trail behind it on a milkweed leaf as I left the Eastern Meadow. Amber snails are described as land snails but they also live in moist environments. I was a bit surprised to see one out in the sunshine when we’ve had such blistering hot days this summer!

At the curve of the path that leads to the Walnut Lane, a busy adult Blue-Gray Gnatcatcher  (Polioptila caerulea) did its best to keep up with a very flighty fledgling that begged insistently as it bounced from branch to branch. As you can see from the slight blur in its photo below, I had some trouble keeping up with the youngster myself! Dr. Ben VanderWeide, our township Stewardship Manager, showed me a Gnatcatcher nest that fell near his home. So imagine how tiny that fledgling had to be at birth to fit in that lovely nest with possibly  as many as four other hatchlings! Look for the white eye ring and the white feathers on either side of  the dark tail feathers to identify these active little birds.

A Short Trip Through More Summer Blooms

A glorious abundance of Cardinal Flower (Lobelia cardinalis) below the boardwalk north of the playground.

I couldn’t detail all the wildflowers and grasses that I enjoyed at Bear Creek Nature Park in the last week, so take a short stroll through the rest of them here. Their color adds so much joy to a summer walk!

Life Calls Us Out to Explore

Little Henry explores Bear Creek Nature Park

Reg and I met twenty-month-old Henry trotting along the path west of the Center Pond as his parents took a rest on a nearby bench. He looked content to just keep moving up the trail, seeing what he could see. It was clear he was happy to be there. Henry reminded me of the third Bluebird fledgling that I described earlier – happy to be off on his own, exploring the big beautiful world that he’s just beginning to understand.

What’s so great is that Henry’s experience is accessible to all of us, no matter our age. If we get out in the natural world with our curiosity and eyes wide open, we can’t help being surprised and delighted by it all – even two small insects determined to fight the other off to pass on their DNA to a new generation. Bird parents exhaust themselves caring for their young. Wildflowers fight their way up out of hard soil to bud, bloom and send their seeds forth into the world. Butterflies, turtles, even fungi recycle death back into life. Life in all its multifaceted glory keeps struggling to persist. And it’s our responsibility as stewards of this glory to keep working hard to make that possible. Here in Oakland Township, the residents have made a commitment to support that call to stewardship – and even in the midst of a tough 2020, I think that’s something to celebrate. Bet you do, too.

Birds, Butterflies, A Few Blossoms and Basking Turtles: Circling the Eastern Side of Draper Twin Lake Park

Looking from the south side of Draper marsh toward the northern prairie.

The eastern side of Draper Twin Lake Park grows more inviting every year. Some of the former farm fields there had been abandoned for decades when Oakland Township Parks and Recreation acquired the property in 2005. Dense thickets of invasive shrubs crowded the shores of the marsh and began to spread within what had been a rolling prairie and oak savanna landscape in the centuries before European settlement.

But restoration is slowly changing this somewhat scruffy park back to its former beauty.  After forestry mowing, the trail by the marsh, once choked with stands of non-native shrubs, now provides open vistas.

The trail on the west side of the floating marsh is now cleared of invasive shrubs so that a stand of native White Pines (Pinus strobus) and other trees can be appreciated.

The dark water of the marsh sparkles between the scrim of trees and shrubs that surround its shores. The roots of grasses and shrubs form a floating mat at the heart of the marsh, creating nest sites for birds large and small. Migrating birds flit through the trees at the marsh edge singing spring songs. Some settle in to mate, nest and raise young; others simply forage, rest and move on.

On warm days in the northern prairie, tiny spring butterflies dart and dance within the dry stalks of last year’s prairie wildflowers and grasses, while the shimmering blue wings of Tree Swallows soar and dip above them. By mid-summer, fresh prairie grasses will sway above fields mixed with the bright colors of native wildflowers and big beautiful butterflies. But even a cool spring day can be beguiling.

So just for a few minutes, escape with me. Muster your imagination as we explore Draper Twin Lake Park together. Listen to a brisk breeze hushing in your ears and feel warm sun on your shoulders as I take a turn around the marsh and then circle the field on the prairie trail loop on a bright spring morning.

In the  Spring, the Marsh is the Place to See and Be Seen!

My Draper Twin Lake Park hiking route

Wetlands mean wildlife in every one of our parks. After parking at the building at 1181 Inwood Road, I headed left, leaving the path to enter the trees that shelter the south edge of the floating mat marsh, pictured at the top of the blog.

The clarion “wika wika” call of Northern Flickers (Colaptes auratus) throbbed overhead as these elegant woodpeckers whisked back and forth in the treetops, competing for mates and territory. This mustached male and his mate will spend the summer with us, nesting in a tree cavity, but foraging on the ground, unlike other woodpeckers; ants are a favored meal for flickers.

A male Northern Flicker challenging other males with his “wika wika” call

A pudgy, green-gray bird hopped about within a tangle of vines, repeatedly flicking its wings and only pausing for a few seconds each time it jumped to a new twig. The male Ruby-crowned Kinglet (Regulus calendula) was enjoying a bit of R&R before flying north, possibly as far as Hudson’s Bay. Imagine! On those tiny wings! There its mate can lay 5-12 eggs in a 4 inch nest woven with grasses, feathers, moss, cocoon or spider silk and lined with finer grass and fur. Never underestimate the little Kinglet!

My photo was a bit blurred by movement in a heavy wind, but bird enthusiasts and excellent photographers, Bob Bonin and his wife Joan, also visited Draper in the last two weeks. In fact, we chatted from a safe social distance when we came across each other at the park.  They generously offered to share some of the photos they took at Draper. So here’s Bob’s rare shot of an excited little male with his crown raised! Thanks for the loan, Bob!

Joan shared two other migrating birds she saw on the east side of Draper. The Black-throated Green Warbler (Setophaga virens) sports such dramatic plumage! It has two versions of its song that has a lot of buzz and a smaller bit of  “tweet” in it. One song is directed at competing males and the other is used to attract females. Find an explanation of both, a video and some recordings here at Cornell Lab of Ornithology’s website.

The Black-throated Green Warbler doesn’t come to feeders and breeds a bit farther north of us and farther into Canada. So it’s a treat to see one! Photo by Joan Bonin.

Joan also provided us with a lovely photo of a Hermit Thrush (Catharus guttatus) at Draper. Cornell Lab reports that this modest little milk chocolate bird with the spotted breast utilizes “foot quivers,” when foraging, shaking its feet in the grass to stir up insects. I will watch for that the next time I see one!

Hermit Thrushes breed north of us where its flute-like call is more likely to be heard. Photo by Joan Bonin.

A pair of Palm Warblers (Setophaga palmarum) skittered around me within the low bushes at the marsh. Traveling from the Caribbean to Canada, they were hungry. Their tails wagged up and down as they grazed along the ground for insects. This one thought it might have spotted something interesting in the crevices of tree bark. Note the brown crown, yellow eyeline, throat and the yellow under its tail.

According to Cornell Lab of Ornithology, ninety-eight percent of all Palm Warblers and thousands of other species breed in the boreal forests of northern Canada, an essential ecosystem!

Looking north, I spotted something large in the trees at the far north end of the marsh. For the second time this spring, I got a distant look at a Great Blue Heron (Ardea herodias) surveying the landscape. I’m so used to seeing these birds wading at the edges of ponds. It always delights me to see them perching high up in a tree, though I know their big, flat nests are always situated at the top of high trees in their rookeries.

A Great Blue Heron looking out from the treetops at the far north end of Draper’s floating mat marsh.

As I moved to the west side of the marsh, I looked up into the frothy blossoms of one of my favorite native trees, the Serviceberry (Amelanchier interior).

The rippling petals of a Serviceberry in a spring wind.

This tree with its plumes of white blossoms in the early spring offers a native alternative to the non-native Callery/Bradford Pear trees (Pyrus calleryana) that flower at the same time. If shopping malls and housing developments bloomed with this native beauty each spring, the fields of our natural areas would not be invaded by groves of the invasive pears. We can hope for a change as the value of native plants is better understood by more landscapers.  Several stately serviceberry trees dot the early spring landscape at Draper Twin Lake Park. Aren’t these clouds of dancing white lovely in the sparseness of the spring landscape?

A native Serviceberry tree makes a perfect replacement for the invasive, non-native Callery/Bradford Pear.

In a shadowy pool beneath low branches on the west shore of the floating mat marsh, some movement caught my eye. A Swamp Sparrow (Melospiza georgiana) dipped its head into the water while balancing on stick, probably plucking insect larvae or small invertebrates  out of the dark water. Fortunately this sparrow is equipped with long legs for wading and doesn’t mind the cold water, if this sopping-wet bird is any indication!

This swamp sparrow stuck its head under water while fishing for insect larvae or tiny invertebrates.

Out at the edge of the floating mat, a pair of Midland Painted Turtles (Chrysemys picta marginata) warmed their shells in faint spring sunlight. Perhaps these two will mate or perhaps they’re just basking together. These two larger turtles could be quite old; Midland Painted Turtles sometimes live over 50 years!

Our Midland Painted Turtles can mate in the spring or fall.

The “boing!” call of a Green Frog (Lithobates climatans) surprised me, so I approached to search the water until I spotted this one. Since the round ear drum or tympanum is about same size as its eye, this is a female Green frog. She may have jumped the gun a bit with the changeable spring weather. Normally, Green Frogs don’t wake from their winter somnolence until the temperature reaches 50 degrees and they don’t mate until the weather is consistently warm. So this female may need to bide her time even though there was a male singing somewhere nearby.

The skin of Green Frogs darkens on cold days so they can soak up more sun.

Back out along the trail on the west side of the marsh, I met a turtle with a ferocious visage, a snout for snorkeling air from under water and an intimidating set of claws! Here’s the steely glare of this master predator, the Common Snapping Turtle (Chelydra serpentina).

This Snapper must have emerged from the mud before heading out to look for companionship.

I’m kidding really. Yes, it did look fierce, but I was being stared down by a small Snapper maybe 8 inches long who probably was just curious.

This small snapper may not yet be mature enough to mate.

I have no idea of its age or what it was doing on trail. According to Wikipedia, a snapper can take 15-20 years to reach sexual maturity and mating is usually done while tumbling about in the  water. So unless this one is older than it looks and was looking for a place to lay eggs, it may have just decided to go on walkabout. Snappers sometimes move great distances to find less crowded habitat, as well as to lay eggs. After all, that carapace, an extremely long neck, powerful jaws and claws are pretty good protection for an adventurous young snapper.

As I stood at the north end of the floating mat marsh, a Green Heron (Butorides virescens) flew swiftly back and forth across the pond. Its yellowish-orange feet trailed behind its bulky body as it landed in the vegetation around the shore. Luckily, Joan later spotted one out in the open in the southeast section of the marsh. One way to spot this colorful bird is to listen for its distinctive “skeow” call;  listen here under the first “calls” recording. That’s the Green Heron sound with which I’m most familiar.

Her husband, Bob, saw a bird that I’d never come across before – and neither had Bob.  The Northern Waterthrush (Parkesia noveboracensis) loves wetlands and according to Cornell Lab of Ornithology, will even settle for a puddle if it’s near cover. It was migrating through on its way from the Caribbean to its breeding grounds in northern Canada. Bob went back to look for it again the next day, but it never appeared. I feel lucky that it “popped out of cover,” as Bob put it, at just the right moment for him to take his photo!

A rare photo of a Northern Waterthrush at Draper Twin Lake Park taken by Bob Bonin.

When I reached the southeast corner myself, a pair of Sandhill Cranes, heads down, were calmly feeding on the floating mat, looking up once a while, and then back to feeding again

This pair of Sandhill Cranes might consider the floating mat a good place for a nest since the marsh creates a kind of moat! Sandhills have nested here before.

As my camera zoomed in on that startling orange eye beneath the crimson cap on one of these huge birds, I hoped that they would choose to nest there as Sandhills did a few years ago. I’d love to see a “colt,” as their fledglings are called, join its parents at the Draper marsh.

A closer look at one of the Sandhill Cranes

That southeast corner of the marsh is full of turtles. I know that Blanding’s Turtles (Emydoidea blandingii) live at Draper Twin Lake Park because I once helped one across the road outside of the park and Donna, the Draper bluebird monitor, has seen them, too. Last week, I thought I saw their slightly domed shells deep in the grass at the southeast corner of the marsh, but they never raised their heads. But Joan Bonin and her very long lens caught this wonderful closeup of one! Thank you, Joan!

Joan Bonin’s wonderful photo caught the yellow throat perfectly, the distinctive field mark of the Blanding’s Turtle.

As I was looking for the Blanding’s turtle,  I noticed a dark lump laying in the water behind a mud flat in the marsh. Could it be? Was that a neck stretched out to gather some sun? I think what I saw was a large Snapper, its neck partially extended along the mud flat, camouflaged as just another black lump in the landscape. Look for its pointed head and eye to the right in the grass. That looks like a large snapper to me!

A large snapper masquerading as just another lump of mud in the Draper Marsh.

Some small upland birds share the southeast corner with turtles and herons. One dark, windy day, my husband and I caught sight of a Yellow-rumped Warbler (Setophaga coronata) and identified it from its characteristic yellow patch above the tail. It appeared to be the more modestly dressed female. Here are the photos I got from a distance 10 days ago and a much better one from 2015.

On a snag near the edge of the trees, a House Wren (Troglodytes aedon) ignored me completely while he belted out his wonderful, bubbling trill. According to Cornell Lab of Ornithology, their sharp, fizzy song sallies forth from Canada, through the West Indies, all the way to the tip of South America.

The distinctively sweet “tweeting” of an American Goldfinch (Spinus tristis) caused me to look up at this little splash of bright sunlight on a cloudy day. The males have donned their brightest colors and execute their rolling flight all over Draper.

A male American Goldfinch posed quite calmly near the southeast edge of the marsh.

On to the North Prairie!

Volunteer Donna Perkins has already found bluebird eggs in two of her boxes within the prairie!

Volunteer nest box monitors like Donna Perkins above are citizen scientists who are gathering data on which birds nest in the boxes, how many eggs they lay, how many days pass before hatching and fledging and how many little birds successfully leave the nest. Donna found six Eastern Bluebird (Sialia sialis) eggs in two of her boxes. And along the prairie’s edge, male and female bluebirds surveyed the area, keeping an eye on their nests.

Don’t worry if you find a nest with eggs in your yard with no adult around. Birds take time off to forage and if scared off of their nest, will usually return. But most often, once the last egg has been laid, the adult will start incubating them most of the day, which helps ensure that they all hatch at the same time, making it easier to care for them.

Tree Swallows (Tachycineta bicolor) move into our township nest boxes as well. Usually, Eastern Bluebirds and Tree Swallows will live in a neighborly way when their boxes are near each other, though occasionally there’s competition for a preferred box. Neither species, however, will tolerate another member of their own species moving nearby. So right now, the Tree Swallows are beginning to construct their nests with a mixture of grasses carefully lined with feathers. What a sight to see these shining blue beauties swooping over the field, periodically opening their beaks to snag passing insects. Joan Bonin got a fabulous shot of two of them in flight over the Draper prairie – an exciting and rare shot! Congratulations and thanks to Joan for sharing it.

A clear song rippled out from the tree line to our right. So loud! What was that? We finally located the rear end of a male Eastern Towhee (Pipilo erythrophthalmus) facing out of the park to the east. In the distance, we could hear his competitor singing as well.  Establishing territory is serious business, so our Towhee in the park never budged an inch, though we waited for almost 20 minutes, listening but frustrated that he kept his back turned. So the photo below was taken last year at Draper. This year’s towhee sang his “drink your teeeeeea” song much more slowly than usual, so it took longer to identify it. Maybe the song had more emphasis that way for the male in the distance!

We came across, though, a sad sight on the prairie – an injured Nashville Warbler (Leiothlypis ruficapilla) feeding on a path but unable to take flight. It appeared right in front of us and at first I thought it had an injured wing. But when it turned its head, its eye was swollen shut. When I asked local birding expert, Ruth Glass, she said that it had probably hit its head on a window. When that happens, the brain can swell and they lose their ability to orient themselves. It was foraging on the ground and fluttered off into the tall grass. I include this just to ask that you do what you can to prevent such window collisions. Here’s a link from Cornell to get you started.

On a happier note, some small spring butterflies floated and fluttered near the prairie trails. I always wonder what criteria make them settle on one stem rather than another; much of their frantic fluttering seems aimless, but I doubt that it really is. I clearly don’t see what they do!

An orange flash in the grass made me think I was seeing my first Pearl Crescent, a common sight on summer days in our parks. But this mid-sized butterfly was an Eastern Comma (Polygonia comma). The upper (dorsal) side of both its forewings and hindwings are tawny orange with black spots. It was born last fall and is referred to as the “winter form”; it overwintered as an adult and will now mate and lay eggs. The caterpillars from those eggs will hatch around the Summer Solstice (June 21) and the offspring from that generation (referred to as the “summer form”) will still have orange forewings, but their hindwings will be much darker than this one.

An Eastern Comma sipping on an open dandelion bloom. It wintered over and will now seek a mate!

But look at the underside of this butterfly’s wings! The winter form Eastern Comma spends the cold months under tree bark or inside logs; that mottled brown design does a nice job of camouflage while they are hibernating, I would imagine.

The pattern on the underside of the Eastern Comma’s wings camouflages it during hibernation under tree bark.

A female Cabbage Butterfly (Pieris rapae) paused to sip at a dandelion, just as the Eastern Comma did. One good reason not to remove dandelions from your lawn in early spring is that native bees and butterflies benefit from the nectar of this non-native flower when few other blossoms are available. Male Cabbage Butterflies have one spot on their forewings; females have two.

A female Cabbage Butterfly benefits from the presence of dandelions.

A flash of lavender blue appeared in the grass – a Spring Azure (Celastrina ladon)! This little insect is only as big as your thumbnail. Its host plants (the ones on which it will lay eggs) include Wild Cherry, Flowering Dogwood, Gray Dogwood and Blueberries. This one didn’t stop long enough for anything but a photo of a blurry smudge of blue. So here’s the best photo I’ve ever gotten of one – only because it made the rare move of posing for a moment! If you see a blue blur flying by during July through September, that’s the Summer Azure (Celastrina neglecta), a different species.

The blue open wings of the tiny Spring Azure butterfly in a photo from 2015.

A surprise on the prairie was a Carolina Locust (Dissosteira carolina). I’ve never seen one this early in the year! Could it have rushed the season like the Green Frog? Usually the nymphs arrive when the weather is much warmer and this one appeared to have its wings which would indicate that it’s an adult. So I’m puzzled. Normally I would send this photo  to Dr. Gary Parsons, an insect specialist as Michigan State University – but I believe the university is closed during the pandemic. So if any reader has more information than I, please leave a comment to that effect. I love its beady eyes, but wonder if it survived the cold nights that followed.

Restoring Complex, Nourishing, Chaotic Beauty

Draper Marsh, looking south toward Inwood Road

Farm fields can be so lovely in spring – neat rows of green as far as the eye can see taking the shape of a field’s rolling contours. But as I’ve watched the stewardship crew recreate the natural landscapes in our parks, I’ve come to love even more the glorious chaos of wild natural areas. Here at the eastern section of Draper Twin Lake Park, the fields of last year’s stalks once again host nesting Bluebirds and Tree Swallows, looking like shining bits of sky taking up residence in our midst. Turtles safely sally forth from the marsh mud to mate and warm their chilled shells in the pale spring sunlight. The dark water around the floating marsh hosts frogs, several jousting Red-winged Blackbird couples, and those ancient and elegant cranes. Weary avian travelers find respite, nourishment and for some, a place to raise their young. As years of invasive overgrowth are cleared, the old farm fields bloom with a rich array of native trees, grasses and wildflowers. Once again the marsh and the prairies take up their ancient role of providing shelter and nourishment to a whole and healthy community of wildness.  During this difficult time, restoration comforts and delights me – and many of you, too, I believe, since new visitors have recently explored our parks. Thanks for accompanying me, even at such a great social distance.

Lost Lake: A Small Park with a “Magic” All Its Own

A wonderful stump for sitting along the water beneath the trees at Lost Lake.

Lost Lake Nature Park may be small, only about 58 acres, but it’s a big resource for all kinds of wildlife – including us humans! Roughly 10,000 years ago, the glaciers sculpted this park with its rolling woodlands that now slope down to shady wetlands dotted with ferns and mushrooms. The deep Laurentian ice sheet also eventually dropped enough material to create a huge hill, one of the highest places in the township – now a magnificent sledding hill in the winter months.

The glaciers also gifted us with a large kettle lake. A huge chunk of ice broke off the ancient glacier and melted, gradually filling its hole with water as the glacier retreated, leaving rocks, soil and gravel around the lakeshore. Anglers – both human and avian – now pull fish from the lake and in the fall, a variety of birds seem to find it an ideal place to rest, socialize and feed before heading for points south.

So please join me on the dock as birds call and forage on the far shore or mud flats. Wander with me up and down hills in the woodland dimness, where a dragonfly devours its kin (!), green pools glow in the distance and a motley collection of colorful mushrooms appear and disappear within the bed of dark, moist leaves left from the summer evaporation of a vernal pool. It really is a “magical” little place!

 

The Pond Provides R&R Before the Big Push South

Part of a family of Canada Geese call, feed and relax at Lost Lake

Almost any time from spring to fall, the honking of Canada Geese (Branta canadensis) greets me as I step from my car at Lost Lake Nature Park. What appeared to be a family of about eight glided peacefully around the lake on a cool October morning. A noisy male declared himself to all comers, sounding his deep “honk” which wards off intruders but is also used right before takeoff. The female will often make a higher “hink” call in response, especially when in flight. This group eventually took off toward the east after a relaxing hour or so cruising the pond.

Canada Geese after taking off from Lost Lake

Far across the pond, a tall white figure lifted its knobby, backward knees as it stalked along in the mud. A Great Egret (Ardea alba) stuffed itself on creatures too far away for me to see; frogs, small fish, dragonflies, and grasshoppers all contribute to an Egret’s diet.

The Great Egret had a wildly successful afternoon foraging along the north edge of Lost Lake.

For a while, the egret just stared up into the sky, something I’ve never seen an egret do before. Maybe it was just being extra cautious, though I saw and heard nothing threatening. Or maybe it was just curious?

The Great Egret studying the sky for some unknown reason.

Most of the other birds at Lost Lake camouflage almost perfectly again the background of the browning vegetation on the mud flats. It pays to scan the surface with a pair of binoculars until I see movement. My camera and I could just barely discern three Wood Ducks (Aix sponsa) slipping through the slim waterways that thread  through the low-growing aquatic plants that blanket parts of the lake.

Wood Ducks are tough to see  in the open water between the aquatic plants. The male is in the center; left is most likely the female and the one bringing up the rear may be a juvenile.

On the same busy day at the lake, a Great Blue Heron (Ardea herodias) stepped out of the reeds on the far side. It was a wary creature, stalking along the edge to do a little hunting, but repeatedly slipping back into the tall plants to hide. Finally I caught it in the open – but just for a moment! It didn’t seem as lucky or perhaps as skillful as the Egret in finding food. Young Blue Herons are on their own two or three weeks after leaving the nest, so I wondered whether this was a slightly nervous juvenile or simply a wary adult.

A Great Blue Heron slipping into and out of plants along the north edge of the lake

A young Green Heron (Butorides virescens) appeared in my binoculars as I swept my gaze across the lake’s mottled surface.  Since the heron stood almost completely still, I would never have spotted it without them. Its striped neck is the most obvious sign that this one is a youngster. Shortly,  this solitary bird will head out on it own to spend the winter in Florida, along the Gulf Coast, or in the Bahamas. How young birds who often travel alone know where to spend the winter remains a mystery. According to the website of the University of Colorado at Boulder, recent studies indicate that migrations destinations may be genetically determined through years of evolution.

A young Green Heron probed the mud flats for fish, snails, amphibians, whatever he could find before migrating to Florida, Cuba or the Bahamas.

The high, keening cry of the Killdeer (Charadrius vociferussounded over the lake as a trio of them flew across the pond, wings akimbo at a sharp angle. They too stayed at the north edge of the lake, poking along the muddy shore for a very long time. My binoculars could reach them, but they were too small for my camera to see clearly. So I sat down on the deck and waited. Finally, the three flew in my direction and settled on a grassy flat. They too were nicely camouflaged by the browning foliage in the background, especially the bird on the left!

Three killdeer finally took pity on me and landed close enough to the fishing platform to snap what might be a family portrait.

As I left the floating dock, I noticed a sparkling patch on the surface of the water. On closer inspection, it turned out to be a hatch of Whirligig Beetles (family Gyrinidae) swirling across the surface with sun on their rounded backs.

A swarm of Whirligig beetles, some sparkling in the sunlight

These little creatures seek protection in groups, swimming frantically in circles when agitated. Their divided eyes are believed to allow them to see both above and below the water’s surface. Nonetheless, periodically a fish dashed to the surface and a few disappeared, leaving a gap in the swarm,  as you can see in the 10 second video below.

.

A closeup shot (below) shows these rotund insects more clearly. You can see how each little beetle makes its own tiny ripples as it energetically rows over the surface with its hind and middle legs. The front legs are used to grab other insects, including those unlucky enough to fall in their midst!

Whirligig Beetles rowing around in a swarm on Lost Lake.

At the water’s edge, a small American Bullfrog (Rana catesbeianus) sat quietly in the shadows, its face turned to the sunlight. I mistook it at first for a Green Frog (Rana clamitans), but they have rigid folds down either side of their back. This little bullfrog had a fold that curled around its tympanum, the eardrum-like circle on the side of a frog’s head. Also its eyes sit up high on its head; Green Frogs’ eyes are lower with little noticeable bulge. I wondered if this small frog stared so steadily because it was trying to see the shadow of an insect flying by, silhouetted against the light. I wish just once I’d get to see that long tongue flash out and snag one!

Several bullfrogs jumped into the water as I came off the dock, but this little one kept concentrating on looking for an insect – or perhaps just enjoying the sun on a cool day.

On one of my trips to Lost Lake, I came across a mother and son team fishing on the deck. The young man, Zach Adams, had just pulled in a Largemouth Bass (Micropterus salmoides) – and I believe, on his first cast! His mom, Cheryl, took a photo before her son released it back into the water. I’m happy that she kindly shared her photo with me, so I could show you one of the denizens that live below the surface of Lost Lake. This bass is what researchers call an “apex predator,” which means that its presence maintains the balance of species within the lake.

Then, Into the Steeply Sloping Woods

The high point of the woods at Lost Lake slopes down to a dry vernal pool at its foot

The path that leads to the woods was filled with dappled light one October afternoon. A Bumblebee (genus Bombus) slipped its long tongue into the last few flowers ringing a Bee Balm blossom (Monarda fistulosa) that miraculously still survived in October. You can see the stamens protruding from the tubular upper lip of each flower, while the three lower lips offer what the Illinois Wildflowers website describes as “landing pads for visiting insects.” This bumblebee has made the most of the landing pad, I’d say!

A Bumblebee searched industriously for any nectar left on an aging Bee Balm blossom.

Where the sunlight found its way through the leaves, another Bumblebee  nuzzled a Showy Goldenrod (Solidago speciosa) looking for whatever bits of pollen were still available before this late season goldenrod turned brown.

A Bumblebee exploring the possibilities of one of the late and lovely Showy Goldenrods.

I came across a cloud of spreadwing damselflies fluttering among some small trees in the first shadowy light of the woods. I’d never seen so many at one time! I believe they were Emerald Spreadwings (Lestes dryas) because of their green sheen and slightly stockier appearance than most damselflies. But I never got a definitive identification.

A whole group of Emerald Spreadwing damselflies settled on the plants and trees just before I entered the woods.

When I spotted a female Autumn Meadowhawk (Sympetrum vicinum) in their midst, I snapped a quick photo. I didn’t realize until I saw it in my computer that it was consuming one of the spreadwings! Yikes. No honor among Odonata evidently; they are members of the same order! Well, an insect’s gotta do what an insect’s gotta do, I guess.

I believe this male Autumn Dragonfly is holding a half-eaten spreadwing damselfly!

A Beautiful and Strange Collection of Mushrooms

Violet Polypore Mushrooms, Stereum and a Hickory Tussock Moth all share a log in Lost Lake Nature Park.

The fallen log picture above hosted undoubtedly the most beautiful assemblage of mushrooms I’ve ever come across on my hikes. Violet Polypore Mushrooms (Trichaptum biforme) stepped delicately down the side of this log while orange shelf/leaf fungi (genus Stereum) formed ruffles across the surface. Down at the bottom edge, a white Hickory Tussock Moth (Lophocampa caryae) paused to either nibble a bit – or just enjoy the artistry along with me. This tableau captured me so completely that I just sat down on a nearby log to appreciate it for several minutes.

I love entering the half-light of the forest at Lost Lake Nature Park. The topography is so dramatic! The back side of the sledding hill, covered in trees, slopes away to what was a vernal pool last spring. Now I can walk out on the spongy black soil at the foot of the slope and look for mushrooms. The moisture and the bed of rotting leaves is ideal territory for them.

I’m a complete novice at mushrooms, so I want to acknowledge and thank the knowledgeable fungi fans on two Facebook pages that helped me identify some of these: Mushroom Identification and Michigan Mushroom Hunters. I assume that the members are enthusiasts, not necessarily mycologists, so please don’t take their identifications as scientific proof – just much better and more educated guesses than mine! [Important Note:  I enjoy mushrooms for their place in the wildlife food chain and their beauty in natural habitats. Please don’t pick them in our parks and don’t eat any wild mushroom unless a qualified individual tells you they’re safe. Lots of our mushrooms are toxic in various ways, so beware!]

In the stippled light of the sloping forest, Russula mushrooms(genus Russula) thrust their caps above the leaf litter. Russulas are “ectomychorrizal” which means they contribute to the “wood wide web.” They form the spore-bearing, visible part of a huge, unseen network of fungi beneath the soil that allow trees to communicate and feed one another and that in return can feed off sugars in the tree roots by tapping into them. [Click on photos to enlarge; hover cursor for captions.

Having attended a great mushroom event at Lost Lake Nature Park in 2018, I recognized this little mushroom as a Pigskin Poisonous Puffball (Scleroderma citrinum). What gives away the toxicity of this little puffball is that if you cut it open, it’s solid black inside!

The Pigskin Poisonous Puffball is a handsome mushroom with a great name – but don’t eat one!

Some mushrooms, of course, grow on dead wood, rather than emerging from the ground. I found two protruding in a somewhat spooky fashion from a snag (standing dead tree) in the moist soil of the former vernal pool. This one is in the genus Pholiota. It is the spore-bearer for unseen fungal threads called hyphae inside the wood that, according to Wikipedia, help break down decaying wood. In other words, like all fungi, they are recyclers!

A Pholiota mushroom whose role is to break down decaying wood into nutrients it can use.

Another recycler poked out of a nearby snag, though it looked like its job was nearly over. A Facebook mushroom enthusiast named Greg identified it as being in the genus Gymnopilus which is in the same family (Strophariaceae) as the Pholiota mushroom above. This one has a “veil,” a partial ring on the stem that mycologists think may help protect the gills under the cap where the reproductive spores are released.

This aging mushroom has what mycologists call a “veil,” a partial ring of material around the stem meant to protect the gills under the cap where the spores are released.

In the same area, a beautiful “foliose” or Leaf Lichen draped like lace over a dead branch. A lichen is a strange life form that is not a moss or any other plant.  According to Wikipedia, it “arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.”  Some live on wood like mushrooms,  but they don’t draw nutrients from it.  They don’t have roots but pull water and nutrients from the air and dust.  Their relationship with one of their partners, like algae, allows them to photosynthesize.  These ancient organisms  can look like leafy plants, drooping moss or powder on the surface of a rock.  Have a look at its varied forms on the Wikipedia page.  Lichens are so common in nature and yet live and grow (verrrry slowly!) in such an alien way.  They intrigue me! Here’s the big, beautiful one I saw at Lost Lake.

A Leaf/foliose Lichen. Lichens cover 6% of the earth’s surface and are not plants!

And here’s a sight that just delighted me for no particular reason.  But look at the cool knotholes on this downed sassafras log, like open mouths silently singing!

I just got a kick out of the three open mouths of these knotholes on a fallen tree.

High on the Hillside, Autumn Wildflowers

Sassafras trees seem to take on fall colors much earlier than other trees in the forest.

We often think of  summer when we think about wildflowers. But cool weather is the perfect bloom time for many plants. Some of the ones at Lost Lake Nature Park thrive between patches of light on the high slope of the forest; some are happiest down by the lake. So here’s a small assortment of plants that love fall as much as I do!

Lost Lake Takes Me Back to the “Magic Places” of My Childhood

A cool green pond with hills sloping up behind to a forest clearing

When I was a child, nothing delighted me more than finding what I felt were “magic places.” Usually these spots were hidden ponds, small clearings in a woodland or sudden openings between trees that gave me a new perspective on a familiar spot.  Lost Lake brought back that childhood sense of “magic” for me on my final walk this fall.

Along Turtle Creek Lane on the west side of the park, I came across the oval pond in the photo above. The woods rise steeply at the back, as if throwing a protective arm across it. I found some park property across the lane that I hadn’t explored before. It  featured a small clearing in the woods and an unexpected view into a grand marsh that is on private land .

A view from park property into a huge marsh on private land to the west of the park.

So for me, Lost Lake Nature Park has many charms: a lake bustling with birds on a crisp fall day, a trail lined with damselflies and their treacherous kin, a shady spot that lets me explore, – dry shod –  the moist bottom of a vanished vernal pool. These spots encourage me to take my time, look around, and feel the “magic” I sensed as a child. That feeling of mystery and possibility feeds my desire to save what we can as the climate struggles to adapt to the changes humans have caused. I want to be sure that the children of tomorrow can wander into untamed nature and find the magic that’s still so available to you and I.

Bear Creek Nature Park: Nervous Fledglings Venture Forth and Missing Native Wildflowers Reappear!

Monarch heaven! Common Milkweed flourishes in the eastern meadow at Bear Creek Nature Park, providing lots of leaves on which Monarch caterpillars can thrive.

Summer is finally taking hold. Many of the flowers, butterflies and other insects are late this year, but they’re slowly appearing. Warm days allowed fledglings to emerge from their nests and use their tiny wings to pursue their parents into the fields and marshes, begging to be fed. Many of the young birds look a bit shaky out on their own. Parent birds whisk back and forth, beaks lined with seed or bearing a drooping caterpillar.   Wildflowers, long buried under invasive shrubs that were removed last fall, are emerging from the seed bank in all their glory. A time of renewal for sure!

So join me on a virtual circuit of Bear Creek Nature Park – from the meadows, to the pond, through the woods to the marsh and back to monitor the bird boxes.  I’m happy to have you along!

Fledglings Venture Forth into Sunny Meadows

As I began my walk, rambling along the path through the eastern meadow,  I was suddenly aware of  lots of movement and noisy chattering in the bushes and small trees. Little fledglings were perching there, occasionally fluttering and calling, reminding their busy parents to bring them a meal. A little Red-winged Blackbird (Agelaius phoeniceus) struggled up onto a branch near an adult who took off immediately to look for food, leaving the youngster looking just a bit insecure!

A fledgling Red-winged Blackbird seems not quite ready to be alone in the world!

Another youngster perched on a branch seemed on high alert as  it looked out on the meadow.  The striped feathers and the fact that adult Song Sparrows (Melospiza melodia) were nearby makes me think that it’s their fledgling.

A young Song Sparrow looks anxiously off into the distance, waiting to be fed.

On a birding walk a week earlier, Dr. Ben VanderWeide, our township Stewardship Manager, heard the high, wheezy call of the small Blue-Gray Gnatcatcher (Polioptila caerulea). Looking up we spotted a tiny nest near the top of a walnut tree. Two adult gnatcatchers were industriously taking turns bringing food to their young. The left photo shows what we could see of the nest and the parent bird from below, though the group did catch a glimpse at one point of a fluttering wing as a nestling leaned out to get the goodies. I’ve included an earlier photo of an adult  Gnatcatcher as it forages. (Click to enlarge; hover cursor for captions.)

Dragonflies and Damselflies Hover and Dart in the Meadows

Dragonflies maneuver across the meadows, moving up, down and forward, in their search for unwary insects or possible mates. The broken wood of the mowed invasive shrubs makes a handy resting place for them.  A juvenile male Common Whitetail dragonfly (Libellula lydia) rested quite near a more adult one, perhaps learning the ropes? The white patches at the bottom of the hind wings are field marks for the juvenile. When mature, the whole abdomen is covered in  a dusty white, referred to as “prunescence.”

The male Eastern Pondhawk dragonfly (Erythemis simplicicollis) also found the woody shards a great place to lie in wait. Though the female is bright green all over, the male’s colors transition from a green face, to a blue-green thorax and a slaty blue abdomen. Quite a handsome fellow!

The Eastern Pondhawk male has a green face and blue-green thorax with a lovely blue abdomen.

Lots of orange dragonflies cling to stalks in the meadow grass. They belong to the genus Sumpetrum, but knowledgeable folk in the Facebook group “Odonata of the Eastern United States” inform me that you can only determine the species of orange dragonflies if you have one in hand with a magnifying glass! And of course, I’m never in a summer meadow, it seems, without seeing the striking Widow Skimmer (Libellula luctuosa).

Damselflies seem more likely to prefer shady areas. But I do occasionally see them in tall meadow grass. Here’s a male Emerald Spreadwing Damselfly (Lestes dryas) I saw when wading through deep grass one warm afternoon. Like dragonflies, they consume a lot of mosquitoes, which pleases me and you too, I bet.

The Seed Bank Awakens as Restoration Begins

Perhaps the biggest thrill for me in the meadows this week, though, was the reappearance of long lost wildflowers. Evidently, beneath those invasive shrubs in the meadows near the pond, seeds and small plants of native wildflowers had been waiting for maybe decades while the fields were covered either with grazing fodder for cattle or abandoned to non-native plants. Now the sun and rain have reached the earth over them again and they are making a comeback!

Out in the meadow west of the pond,  large patches of Butterfly Milkweed (Asclepias tuberosa) have emerged  where previously we only saw a single plant here or there.  And as you’ll see further down in the blog, the Monarch butterflies are already finding them.

Butterfly Weed and daisies BC (1)
Butterfly Milkweed spreads its brilliant orange in two big patches west of the Center Pond.

A spectacular wildflower blooming this year is one neither Ben nor I have ever seen before in Bear Creek Nature Park – the Michigan Lily (Lilium michiganense) – not to be confused with the non-native tiger lilies or the much less glamorous Orange Daylily (Hemerocallis fulva) which originated in Asia. I’d only seen this striking native with its  cup of curved petals, arching stem and showy stigma near the Wet Prairie on the Paint Creek Trail. But this beauty at Bear Creek waited patiently. Once warmth and moisture reached it, up it came just west of the Center Pond.  Michigan lilies can be tempting to hummingbirds and many butterflies. I saw one other bud, so I’m hoping for more!

The dramatic Michigan Lily reappeared in Bear Creek once invasive shrubs were removed.

Tall Meadow Rue (Thalictrum dasycarpum) and Fringed Loosestrife (Lysimachia ciliata)  have staged a comeback, too. A Jack-in-the-Pulpit (Arisaema triphyllum) at the edge of the path had produced its bright green berries on a wide spadix. The berries will turn a brilliant red in the fall.  Who knows what else will emerge over the summer and fall?

Butterflies Arrive – but Not Enough for Me, Yet!

As the mid-summer wildflowers finally begin to bloom, the butterflies are begging to appear.  Sun-loving Butterfly Milkweed hosted a Monarch butterfly (Danaus plexippus) last week. Since this is a female Monarch, we can hope that it will lays its eggs either on the leaves of this milkweed or on one of the many Common Milkweeds in the eastern meadow.

With its long proboscis stuck in a blossom, it appears that this Monarch found the nectar to be just what it needed after its journey to Michigan,

Silver-spotted Skipper (Epargyreus clarus) took a while to show me the bright white spot on the lower (ventral) side of its hind wing. It looks quite different when the “silver spot” is out of sight!

A very tired, worn, Black Swallowtail sat quietly on the path one afternoon. According to Wikipedia, Black Swallowtails are generally longer-lived than other butterflies, unless subjected to bad weather or deprived of food. We’ve had pretty wild weather and the flowers are behind schedule, so perhaps that took its toll on this unfortunate female.

This Black Swallowtail with worn wings and a ragged swallowtail may have been ready to succumb from bad weather and an insufficient supply of nectar.

The Little Wood Satyr (Papilio polyxenes), though, seemed be just fine as it danced along in its bouncing flight from shade into the sun and back again.

Little Wood Satyrs venture into grassy areas that are near the shade of trees.

On to the Pond and Its Frog Song

White Water Crowfoot , an early summer native, is winding down at the Center Pond as the weather warms.

A few blossoms of White Water Crowfoot (Ranunculus longirostris) still peek from the background of abundant Duckweed (Lemna minor) at the Center Pond. The Northern Green Frogs (Rana clamitans) sprawl comfortably among it, floating at the surface and croaking in their banjo voices to attract mates. Since males have a tympanum (circular hearing device near the eye) bigger than their eyes and a yellow throat, this one staring at me intently was definitely a male.

A male Green Frog among the duckweed at the Center Pond

Frog “talk” this July:

I smiled at this small Midland Painted Turtle (Chrysemys picta marginata) who seemed to be listening to the frogs right along with me. But more likely, it was just basking in the warm sunlight after a cold spring, and trying to ignore the frog voices. It’s decorated nicely with bits of  Duckweed.

A small Midland Painted Turtle basked in the Duckweed while the frogs croaked around it.

Into the Woods

The woods just west of Bear Creek Marsh, now more open since cleared of invasive shrubs

The woods on the east side of the park let in so much more light now that the invasive shrubs have been removed! I keep hoping I’ll see more woodland wildflowers because of it. But deer are plentiful at Bear Creek so that’s a slim hope; they love to eat native plants and young saplings. But a couple of woodland flowers escaped their notice, probably because both of them are a bit fuzzy, which puts deer off:  Enchanter’s Nightshade (Circaea canadensis) and Panicled Tick Trefoil (Desmodium paniculatum). Both thrive in the dappled sunlight of the woods so perhaps I will see them spread as sunlight reaches more of the forest floor.

Unfortunately for humans, native Poison Ivy (Toxicodendron radicans) is more abundant in the woods and everywhere else this year. But if you stay on the paths, you’ll be just fine. Look for a three leaved plant on which the center leaf has two “thumbs” but the right and left leaves have only one “thumb” – or look for a vine with that leaf arrangement and reddish “feet” clinging to the bark. Poison ivy isn’t poisonous for animals, though. It produces green berries that turn white in the fall just at the time when other berries are disappearing. So migrating birds gobble them up, enjoying a boost of energy and protein before heading south. Northern Flickers, Bobwhite Quail, Eastern Phoebes, Cedar Waxwings, Woodpeckers, Tufted Titmice, and American Robins all readily eat Poison Ivy berries. Raccoons and deer can eat the whole plant –  and they’re welcome to them, as far as I’m concerned.

Poison Ivy berries feed migrating birds in the fall and the whole plant is browsed by deer and eaten by raccoons!

I followed the song of an Eastern Towhee (Pipilo erythrophthalmus) high in the treetops as I entered the woods. I paused, listened, moved a little – no luck at seeing him in the high treetops. After about 10 minutes of following him from one tree to the next, I gave up and moved on. Luckily, the following week ,the birding group spotted one in the open at Cranberry Lake Park, so at least I can show you a somewhat fuzzy photo of  “the one who got away.”

Northern Cardinal (Cardinalis cardinalis) sang one of its summer songs repeatedly, but it was also hidden in the leafy branches. It’s a classic, summer moment when this  unmistakable, ebullient call reverberates from the treetops!

Damselflies love the “spotlight effect” they get from the filtered light in the forest.  I came upon a female Ebony Jewelwing (Calopteryx maculata) who seemed to be trying to seduce an oddly unmotivated male.  Each posed on a sunlight leaf, but she would periodically fly briefly onto his leaf,  making him jump off for a few moments.  Perhaps she hoped to be pursued, but it was not happening while I was there. I’m afraid I caught her at an indiscreet moment when she paused to poop a few moments later….

A woodland moth slept soundly on a leaf at the edge of the woods one afternoon.  The caterpillar of the  White Slant-line Moth (Tetracis cachexiata) feeds on all kinds of native trees, so it’s a common moth in woods and forests all over Canada and the US. I love the simple design of its bright white wings and subtle yellow stripe.

The White Slant-line Moth’s caterpillar can feed on lots of North American trees so it’s a common sight in forests.

As I walked off the path in the woods to follow the Towhee, clouds of what I think were Hangingflies (genus Bittacidae) rose from the greenery under my feet. These harmless creatures are a relative of the also harmless Scorpion Fly (family Panorpidae) I saw last year at Bear Creek, named for the upward curve of the male’s abdomen.  Both belong to the order Mecoptera. But the delicate legs of Hangingflies cannot support their body weight! So instead they hang by their front legs beneath leaves and capture aphids, moths and other passing insects with their long back legs! Nature always finds a solution. I felt lucky to find one suspended in a spot of sunlight beneath a grass stem.

A Hangingfly can’t stand on its legs. It hunts by hanging from its front legs and catching other insects with the back ones.

Bear Creek Marsh – Wet, Green and Full of Life

A view of Marsh at Bear Creek looking incredibly lush in mid-summer.

The native Buttonbush (Cephalanthus occidentalis) has round, green buds just waiting to burst into balls of white blossoms in the summer heat. It lines one half of the southern platform overlooking the Bear Creek Marsh.

Buttonbush is about to bloom around the southern platform at Bear Creek Marsh.

Here’s what each of those buds will look like shortly!

At the northern platform, my husband spotted an adult Green Heron (Butorides virescens) standing among the cat-tails and rushes across from the deck.  It probably had been probing the mud for food.  According to the Cornell Ornithology Lab, it has a wide ranging diet – from frogs to fish, snails, insects –  even rodents! This one took off and landed high in a tree overlooking the marsh.  I just learned from Cornell that Green Herons actually nest in a large fork in a shrub or tree with overhanging limbs to hide the nest from predators like snakes, crows or grackles. I’d love to see the nest or young of this handsome bird!

As usual in the summer, we looked for slow-moving mounds of mud or moss in the water, a sure sign of  Common Snapping Turtles (Chelydra serpentina).  We eventually saw four, a large one and 3 smaller ones.  It helped when the big one raised its head on that long neck.   The snappers weren’t much interested in each other at the moment and spent a lot of time munching on fresh underwater plants.

Of course, Red-winged Blackbirds dotted the marsh as well, clinging onto cat-tail stems and trilling.  On my first visit, a female scolded me continually while I sat on the bench.  Eventually, I realized that her nest was nearby when a male appeared with a worm or caterpillar in his beak.  He quickly dropped into the grasses near the water to feed his young.

A week later, I saw a Red-winged fledgling watching a male pick apart a cat-tail for seeds.  The little one tried to do the same but with little success since its cat-tail head had already been mostly eaten. Later the small bird landed on a cat-tail in the distance where the male obligingly stuffed some seeds into its beak, thank goodness!

A fledgling Red-winged Blackbird tries to pick apart a cat-tail like the adults do – but not as successfully.

Down below the platform, the American Bur-reed was in all stages of blooming – from buds to blossoms to fruits.  Marsh plants clean our waterways by storing nitrogen and phosphorus that would otherwise starve the water of oxygen.  And Bur-reed is one of the most effective marsh plants, storing four times more than some other aquatic plants.  Plants like Bur-reed are one of the reasons conservationists value wetlands so highly!

As I headed back to the parking lot, I walked back along the boardwalk by the playground pond and noticed a sleepy, nocturnal Gray Tree Frog ( Hyla versicolor) resting peacefully on a lower railing.

Stewardship Fosters Nature Here – and Far Beyond the Township

Thanks for taking a virtual hike through Bear Creek with me.  I find it heartening that the stewardship crew and Dr. Ben are restoring habitat and fostering the wildlife in this park with all of its natural variety.  The invasive shrubs are removed and the seed bank brings back native flowers.  The native flowers bloom and butterflies and other insects thrive by feeding at them.  The nestlings are fed with the insects’ caterpillars and venture out of their nests and nest boxes to soar over the meadows. In the fall, some of them will travel great distances, bringing their beauty and their role in maintaining healthy habitats to places as far away as South America.

The humble bur-reed is allowed to flourish in the marsh. Because it cleans the water as it stores nutrients in its stems and leaves, Bear Creek’s water is healthier as it flows  out of the marsh, eventually reaching Paint Creek.  And the fish and other aquatic creatures and plants there benefit from cleaner water – and on it flows into the intricate, inter-locking systems of the natural world.

Stewardship is a lot of hard work but the reward is that it makes a difference not just in our township, but far beyond.  Wherever the creek’s water flows, wherever native seeds are carried by creatures, wind or water, wherever migrating birds and butterflies travel, a little bit of our township’s stewardship work has played its part in preserving our natural heritage.

Photos of the Week: Hungry Fledglings and Prairies Bursting with Color

Mid-summer on the Eastern Prairie at Charles Ilsley Park

The north and east prairies at Charles Ilsley Park get more glorious each summer as restoration brings the return of colorful wildflowers blooming again in their native soil. Great sweeps of Black-eyed Susans (Rudbeckia hirta) stare  up into the blue sky surrounded by the tousled, lavender blossoms of Bee-balm (Monarda fistulosa) and flat, compact cushions of white Yarrow (Achillea millefolium).

 Tall Yellow Coneflowers (Ratibida pinnata) sway in even the slightest breeze.

Yellow Coneflowers tower over the carpet of color on the Eastern Prairie at Ilsley.

The peaceful  beauty of these undulating prairies on a summer afternoon is mesmerizing. The nodding dance of flowers and the flutter of butterflies among them soothe the spirit much like the sight and sound of a peaceful ocean –  but with such a variety of color and movement! Wonderful!

Last Sunday along the entrance trail, young Barn Swallows (Hirundo rustica) perched high on a dead branch, waiting to be fed. They begged in the usual fledgling fashion, fluttering their small wings rapidly and calling. Finally, a parent arrived (lower left in the photo below), settled and seemed to be considering which to feed first.

Then the adult swooped out across the meadow, gathering insects in its open beak. It returned and managed a short mid-air pause, beating its wings vigorously as it speedily popped food into one of the open beaks.

Then off went mom or dad again to scoop up more bugs! Such a challenging job to feed all four of those hungry youngsters! (One is behind the lowest branch.)

In the center of the park, where restoration planting happened just weeks ago, the melt ponds are drying up, leaving a strange, foamy surface. Water is so crucial for wildlife that it’s always a reliable spot to find something interesting.

A slim bird that I believe was a young Killdeer (Charadrius vociferus), with its naturally worried look, poked along the edge of the pond.  The Stokes’ Guide to Bird Behavior (Vol 2) describes juvenile Killdeer as “very similar to adults except that their upper feathers are margined with lighter edges, their dark neck bands are narrower and often gray or brown instead of black.” I think this one fits that description. Do you agree? Once the young are ready to be on their own, their parents breed again. But the male keeps an eye on the youngsters from the first brood from a distance, while the female incubates the new eggs.

A young Killdeer was not quite as adept at finding food yet. Its parent may feed it as evening comes on.

Two fledgling Eastern Bluebirds (Sialia sialis), with just a touch of blue on their wings,  watched the killdeer from a small, bare tree nearby. No foraging for them right then. Perhaps they were hoping a parent would come to stuff their beaks like the swallows, but at the moment, no such luck. Like the Killdeer adults, their busy parents may also be encouraging their first brood to feed on their own while the adults start a second. (Click on photos to enlarge; hover cursor for captions.)

Some adult birds hung out near the pond as well. A Green Heron (Butorides virescens) was so intent on feeding that it flew toward us to find some open water.

This heron was a skilled fisher! It found a bounty of food in the drying pond. Watch below as it stalks and then catches what appears to be a crayfish nymph. (Use the pause button if you need more time for captions.)

The fiercely territorial Eastern Kingbird (Tyrannus tyrannus) looked remarkably unruffled by the other species exploring the resources of the pond below. And nearby in a tree at the edge of the center field, an adult Song Sparrow (Melospiza melodia) looked as though it must have been preening vigorously since its feather were very ruffled! Drat those feather mites!

Summer turned into an unusually busy time for me this year. So I relish escaping into our parks, where I can watch young birds learn the ropes of feeding, or just quietly enjoy the way Yellow Coneflowers sway above a multi-colored prairie. I recommend it to you as a peaceful alternative to a day at the beach.
