Stony Creek Ravine Nature Park: Summer’s Long Goodbye Begins

The northern meadow at Stony Creek Ravine, partially fenced off for wetland restoration

Summer’s slow demise in late August/early September urged me to acknowledge the need for letting go. Tiny warblers seem to suddenly disappear as they head south. Canada geese begin their practice runs, forming loose “V’s” while trumpeting across the sky. Hummingbirds feed ravenously at any available nectar, gaining 25-40% of their body weight before the long journey to Mexico. Some fledglings still flutter, cry and pursue their parents for a meal; others hone their newly acquired foraging skills. Spiraling through the trees, they seek out the feast of eggs or caterpillars that the pollinators left behind. The meadows quiet down as molting birds hide their bare heads in the greenery hoping to be unseen. Wasps buzz above our outdoor meals, struggling to supplement diminished sources of food.

I spent quiet hours at the newer, eastern section of Stony Creek Ravine Nature Park during these waning days of summer. Come join me in the thinning sunlight and share the ebullience of young birds, the sprays of grasshoppers beneath my feet, and the persistence of butterflies on late summer blossoms that are hallmarks of this transitional season of the year.

Birds, Experienced and Not-so-experienced, Forage and Flutter

I spent my days at Stony Creek Ravine exploring the open fields visible from the top of the Outlook Hill in the eastern section of the park. Much of this area is fenced in to protect small shrubs and trees planted in the re-emerging wetlands. Thousands of native plants were sown there when the old drainage tiles from previous owners were broken to allow water to flow again to the surface. In the spring, pools form and migrating waterbirds glide in for a bit of R&R.

Right now, though, the fenced-in sections are moist but little standing water remains after a hot summer. Social birds flock to the fences to chatter together. Solitary birds, some unusual ones this season, forage within the fence boundaries. Other just need a place to periodically perch while scouting for seeds among the tall grass and flowers within or around the fencing. My photographer friend, Bob Bonin, generously shared some of his excellent photos of birds he came across while patiently waiting near the fence line. It was the right place to be, as you’ll see below!

Young Fledglings Practice Their Foraging, Flying and Landing Skills

One of my mornings at Stony Creek Ravine was in the company of Stewardship Manager Dr. Ben VanderWeide’s Wednesday bird walks. As we entered the park, we spotted several young Eastern Bluebirds (Sialia sialis) whisking in and out of the shrubbery, bits of blue on their wings shining in the sunlight. Three of them spent a remarkable amount of time exploring a hole in a distant snag. We wondered if, being cavity nesters, they were just curious about holes in general or if this hole might have been the one from which they fledged only weeks before.

Three young Bluebirds took turns looking into this hole in a snag. Had it maybe been their nesting hole? We’ll never know, will we?

On another visit, an adult Eastern Kingbird (Tyrannus tyrannus) regally surveyed the area from the tallest branch of a bare tree. Perhaps the adult I saw (below left) was keeping its eye out for its offspring, a juvenile that Bob Bonin saw a few days earlier (below right.) Both birds will shortly be heading to forests in South America where they will feast on fruit during the winter. [Click on photos to enlarge.]

Bob also spotted a female Orchard Oriole (Icterus spurius) and perhaps one of her offspring. Like their bright orange relatives, the Baltimore Oriole, these birds build pouch-like nests. They breed in our parks each year but are less noticeable to most of us. The male is a dark russet orange and black and the female is yellow. Orchard Orioles depart for their overwintering grounds earlier than many other birds, so by now they’re on their way to Central America.

I fell instantly in love with this little puffball. Local bird expert, Allen Chartier, tells me it’s a juvenile Song Sparrow (Melospiza melodia). This young bird can relax a bit longer than the distance migrators. Song Sparrows travel around just enough during the winter to keep themselves out of the worst of Michigan’s cold season.

This wee Song Sparrow juvenile can use autumn days to perfect its foraging skills. It will need them to handle a Midwestern winter.

A few other small birds appeared for me along the fence line. A little Eastern Wood-Pewee (Contopus virens) sings one of the most recognizable calls of a summer day – the rising “Pee – weeeee?” that sounds like an oft-repeated question. Birdsong beginners, like me, appreciate a song that identifies this little flycatcher who can be difficult to spot otherwise. Bob Bonin spotted a little Chipping Sparrow (Spizella passerina) who’ll be heading off to Florida before long. And he also saw a young Field Sparrow (Spizella pusilla) with its telltale pink/orange beak and feet.

Breeding Season Over, Adult Summer Visitors Relax Before Migration

My friend Bob brings patience as well as skill to his photography. He caught sight of two birds at the park that people rarely see and waited until he got the shot he wanted. One was a “leucistic” Savannah Sparrow (Passerculus sandwichensis) which means that it had partial pigmentation loss. Unlike the complete loss of pigmentation of albinos which also causes white, pink or red eyes, leucistic animals have partial pigmentation loss and their eyes are dark. Bob also waited over two hours for a closeup of another unusual bird, a Sedge Wren (Cistothorus stellaris) as it foraged for spiders and insects down in the dense grass, sedges and small shrubs within the fence. This is ideal habitat for Sedge Wrens, but since they are unpredictable nomads, we can’t count on seeing them every year.

Stony Creek Ravine hosts some more common summer residents as well – and we’re always glad to see them as well.

The plaintive cry of a Red-tailed Hawk (Buteo jamaicensis) fell from the trees around a marshy area filled with sedges (genus Carex), ancient, grass-like plants that thrive in moist ground. When it suddenly appeared overhead, I caught it twice with my camera, once like a magnificent arrow streaking across the sky, and once in mid-scream from a prey’s eye view. Glad I’m too big to be carried away for dinner!

The fierce glare of a red-tailed hawk against the summer sky. What a striking, powerful predator!
The cry of a Red-tailed Hawk must put fear in the heart of every rabbit or field mouse within earshot.

Down Below, Butterflies, Bees and Late-Season Grasshoppers Harvested the Last of Summer’s Bounty

One of late summer’s most glamorous residents appeared in August, the glorious Giant Swallowtail (Papilio cresphontes), North America’s biggest butterfly. If you’d like to attract some to your garden, two of its favorite native plants are Rose/Swamp Milkweed (Asclepias incarnata) and all of the goldenrods, both of which bloom in late summer and early fall If you can also tolerate thistles, they seem to favor them quite a lot more than we do!

At first glance, it’s easy to confuse the black and gold-spotted dorsal ( upper) sides of the Giant Swallowtail and the Eastern Black Swallowtail (Papilio polyxenes,) especially if they’re flying. But compare the ventral (lower) side of the wings. The underside of the Giant Swallowtail’s wings are yellow and the Eastern Black’s (below) are black. I was lucky to see both feeding at thistles during my visits to Stony Creek Ravine.

Smaller butterflies and moths float and flutter in the grass as well, of course – and one well-fed caterpillar just chews its way along.

As regular readers know, I’m intrigued by insects of many kinds and want to convince all comers to just enjoy them. So here are some of my other favorites during late summer at Stony Creek Ravine.

Hardy Native Wildflowers Mix with Plentiful Non-natives until Restoration Advances.

A glorious spread of native wetland Black-eyed Susans (Rudbeckia fulgida), a relative of the other Black-eyed Susan (Rudbeckia hirta) that thrives in all types of open habitat.

Though the fields in the eastern section of the park have been cleared of many non-native shrubs, native wildflowers are not plentiful yet in the fields at Stony Creek Ravine Nature Park. The long stretch of native wetland Black-eyed Susans in the photo above is a glorious exception. Restoration of a healthy habitat with more diversity has begun with seed planting at this large park, but it will take several years to come to fruition. So I have to smile seeing sturdy native blooms holding their own amidst the non-native plants on the Outlook Hill, in the surrounding fields and near the wetlands. Here are some of the other stalwart native competitors declaring their presence at this amazing 268 acre park.

One native plant that’s rampant at the park this year may not please everyone – Common Ragweed (Ambrosia artemisiifolia.) So if you suffer from hay fever, now is not a good time for your visit! Please remember, though, ragweed pollen is dispersed by the wind; that’s why it ends up in noses. So please don’t blame your sneezing on innocent goldenrods that bloom at much the same time. Their pollen is heavy and falls right to the ground, far from sensitive noses!

Oh! And One Creepy Fungus that I Just Have to Share!

One of the benefits of being in a birding group is having more eyes and ears seeking out interesting details in the landscape, plus access to other people’s areas of expertise. For example, the energetic, hardworking summer natural areas stewardship technicains each year provide me, at least, with younger eyes and ears, youthful enthusiasm and a knowledge base more updated than mine!

In late July, while walking up the path to the ravine, Emma Campbell, one of this summer’s technicians, stopped to comment on a spiky bump in the trail that most of us stepped around, assuming that it was just a sharp piece of root. But Emma carefully broke off one small portion and finding it white inside, correctly identified as a fungus spookily called Dead Man’s Fingers (Xylaria polymorpha). Evidently it’s a common fungus that grows from rotting wood; as you can see below, this one emerged around the remains of a stump. What a Halloween-ish discovery! Thank you, Emma! Wish I could have creeped out some friends with this one when I was a kid!

A fungus called “Dead Man’s Fingers” for obvious reasons.

The “Oohs” and the “Ughs” of Nature’s Impulse to Keep Fostering Life

Unless you are a hopeless romantic, every close observer of the natural world knows that nature is not all “sweetness and light.” The lives around us in nature can be both big and beautiful like the Great Blue Heron (Ardea herodias) or small and homely like the Fall Webworm (Hyphantria cunea). It can be full of tenderness, like birds tirelessly feeding their young or ruthless in its need to survive, like a hawk tearing the flesh of its prey. It can be inspiring like a flight of fall geese or macabre like the Dead Man’s Fingers fungus. But whatever qualities it has for us humans, nature itself doesn’t judge and never despairs. Against all odds, nature just proceeds eon after eon in service of sustaining life, whatever that takes. The “nature of nature,” as it were, is to adapt, survive and assure the existence of the next generation.

We humans, as just another species, would do well to take a lesson from the creatures and plants that surround us. We cannot afford to despair as our behavior changes the climate, threatening life on this special blue planet. Generations could stretch on into the future indefinitely if we would do as all other creatures have evolved to do – adapt, change, survive and above all, work hard to ensure that long after we’re gone, life continues on a healthier path than we’re on right now. If we do, our grandchildren and their descendants will honor our efforts and that honor will be well deserved. Let’s not disappoint them.

Watershed Ridge: Changes Afoot!

The field above the western marsh at Water Ridge in late autumn

Until now, Watershed Ridge Park’s 170 acres have been a challenge to explore. A visitor needed to be ready for waist-high fields and of course our township’s wonderful wetlands in all their wet-footed glory. But in early November, Dr. Ben VanderWeide, the Oakland Township stewardship manager, laid out its first trails which were created by the maintenance crew. The new trail skirts the edges of fields still sown and harvested by local farmers who keep invasive species at bay until this rolling landscape can be restored to the wildflowers and grasses that are part of our historical legacy. But even in the autumn, the hedgerows and woods that edge the fields provide shelter and sustenance to a variety of birds and this November, even one special migrator, as you’ll see below. And in summer, birds sing and nest, wildflowers bloom in profusion and butterflies, moths, bees and other insects enjoy the bounty.

So come take a walk with me along the edges of the newly created path which starts from the parking lot. It’s a very muddy path right now, so I recommend wearing old shoes! Or maybe you can walk just off the edges in the tall grass to save the grass seed planted on the paths in anticipation of next spring. Follow along on the map that Ben’s provided to show you the route.

I’ll introduce you to a few creatures that make their home here and some that are just passing through. But mostly, I want to give you the “lay of the land,” and show you some stewardship projects underway that will make this park even more beautiful for us and nourishing for wildlife as the years go on.

Follow along by looking for the letters in the blog post indicating spots of interest on my hike.

The Path West to (what I’m calling) Southwest Field 1 (A on map)

The new trail crossing Southwest Field 1 to the hedgerow cut

This trail begins in the parking lot, follows Buell Road west and then gently curves north. The parking lot on Buell can be a great place to stand quietly and look for birds in the tall trees and in the tangle of vines that weave through them. On my first November visit, I watched European Starlings (Sturnus vulgaris) wheeling down into the treetops. Eventually one moved close enough for a photo. Its iridescent breast glowed emerald in late afternoon sun, accenting the white dots of its winter plumage. Despite being aggressive birds, their swooping flocks, called “murmurations, ” that rise, fall, flow and ripple through the sky are truly mesmerizing.

A solitary European Starling in its winter garb. Quite a beak, eh?

A House Finch pair (Haemorhous mexicanus) peered out from the vine-covered shrubbery. The male’s cherry red head and breast gets its color from the pigments in the food it eats. For that reason, red fruits are particularly favored since the brown and white striped females prefer the males whose red is most vivid. [Click on photos to enlarge.]

I followed the curving path to where it cut between Southwest Field 1 and the next one north, which for now, I’m calling Southwest Field 2.

Creating a Wetland Extension (B) in Southwest Field Two (C)
The hedgerow cut between Southwest Fields 1 and 2

As I stepped between the two fields, a small bird landed on a shriveled wildflower lined with seeds. At first, the red patch above its eyes made me think it was an oddly colored House Finch – but, no. I knew that scarlet crown, pinkish breast and dramatic striping had to be some unfamiliar bird – one I’d never seen before. It turned out to be the Common Redpoll (Acanthis flammea), a winter finch that rarely comes this far south in Michigan; this little guy flew all the way from the Arctic, the boreal forests of Canada’s far north or Hudson’s Bay! In fact, Cornell Ornithology Lab says a Redpoll banded in Michigan once showed up in Siberia! (Check out the link for other amazing facts about these little birds!) Redpolls are unpredictable, erratic migrators. This year significant numbers of them chose to land in our area, according to Ruth Glass, local birder extraordinaire. I feel very lucky to have seen this one!

A Common Redpoll which is not so common in southeast Michigan which is the extreme southern edge of its winter range.

Once past the hedgerow, I walked over to the edge of the slope to look down on one of Watershed Ridge’s new wetlands. Ben, our Stewardship Manager, wanted to restore wetlands in some of the fields that have been agricultural for so long, often in areas that had been tiled or ditched to drain wetlands when the area was first farmed. The restored wetlands will capture and filter nutrients and sediment from the water before it enters creeks, streams and lakes downstream. The US Fish and Wildlife Service (USFWS) helped design the grade of the slope around the new wetland to gather the rain water that runs down from the fields above. They also provided the crew and equipment to insure that the grades of the slopes were created accurately according to their design so that they would hold water. The construction took place in October and seems to have worked beautifully; the pool was beginning to fill nicely after late autumn rain.

The expansion of the wetland in Southwest Field 2

Now the stewardship team will wait to see how the wetland works over the next year. For example, will it dry like a vernal pool or have some standing water all year? Then Ben can decide which plants will thrive in or around this new water feature. It may look like a modest pool at the moment, but in time, we can hope it will flourish with aquatic and wetland plants that will feed and protect wildlife.

A flock of other winter visitors, the Dark-eyed Juncos (Junco hyemalis), fluttered from one corner of this huge field to the other. A solitary Junco let me capture its portrait at the shadowy edge of the woods to the north. In contrast to the Common Redpoll, this sleek, black-and-white sparrow with its white outer tail feathers is a regular winter visitor from the Canadian forests.

Dark-eyed Juncos are often the first winter migrants to arrive from northern Canada.

Nearby a year ’round resident of the area, a male Downy Woodpecker (Dryobates pubescens) spiraled around a branch searching for food beneath the loose bark. It looks like it’s given this perch a good going-over! These little woodpeckers often like to hang out with mixed flocks of birds for protection from predators.

When I visited Watershed Ridge Park in early November, some insects still kept me company. At the muddy edge of a tilled field, a Carolina Locust (Dissosteira carolina) crept slowly over the furrows, perhaps looking for the soy beans left after the harvest. The least destructive of locusts, these insects do eat grasses but sometimes beans are their preferred diet, according to the University of Wisconsin Milwaukee Field Station.

A Carolina Locust may have been looking for soybeans left behind after the farmer harvested them.

The Field Two trail turns back east and heads for Field Three (E) just east of the parking lot by cutting through a hedgerow (D).

Cut through the hedgerow from Southwest Field 2 to Field 3
Following the Trail into Field Three (E), Then Off Trail Through the Forest (F)
Trail from Field 2 through the hedgerow to Field 3

From the hedgerow cut, the trail runs alongside the forest and then circles the field to return to the parking lot. But my choice one November afternoon was to go off trail through the woods. This moist woods is alive with frog song in the spring months. But now it’s almost silent, so that the crackle of my footsteps on the deep layers of Northern Red Oak (Quercus rubra) and White Oak (Quercus alba) leaves sounded loud and a bit intrusive.

Red Oak leaves have pointed lobes tipped with bristles and White Oak leaves have rounded lobes.

Among the leaf litter, I noticed a Northern Red Oak leaf with a peach-colored pom-pom attached. With help from Dr. Gary Parsons at Michigan State University’s Entomology Department, I learned that it was a Woolly Oak Leaf Gall, the winter abode of a very tiny insect larva called a gall wasp. Callirhytis lanata, this particular gall wasp, would look like a dot on your finger tip; it’s only 1-8 mm long, about a third of an inch! When the wasp lays her egg on a Red Oak leaf, either she or the larva which hatches from egg secretes a substance that stimulates the leaf to create these gall tissues that form the pom-pom. Inside the gall, the larva eats those tissues, pupates, and a tiny new adult wasp emerges in the spring. If the gall isn’t invaded by a predator, the fuzzy little pom-pom is a safe, cozy spot to spend the winter!

A Woolly Oak Leaf gall forms a warm, enclosed getaway where the larva of tiny wasp can spend the winter.

Farther east in this woods, I was confronted by what appears to be the deadly effects of invasive species, those life forms that may be relatively harmless in their native lands, but become destructive where they are not native. I came across a graveyard of large trees (G) that had died and fallen rather than been cut by humans. Ben’s best guess was that they were likely Ash trees (genus Fraxinus) decimated by the Emerald Ash Borer (Agrilus planipennis). Ash trees in the native range of Emerald Ash Borer in northeast Asia share evolutionary history with this insect and can protect against damage; trees in North America and Europe are naive to this insect and not yet resistant. Since it was discovered in our area in 2002, Emerald Ash Borer has killed millions of ash trees just in southeast Michigan. Ben tells me that this insect infestation continues to be a problem in our township. In the same way that Dutch Elm Disease affected elms years ago, it is still killing small ash trees before they get a chance to mature. So please don’t transport firewood from our area which can further spread this kind of devastation!

A large area of fallen ash trees killed by the Emerald Ash Borer between 2002 and the present.

Lichens and moss appear on fallen logs throughout this forest, but I tend to notice them most in the austerity of autumn. Wikipedia describes lichens as “self-contained mini-ecosystems” or composite organisms made up of a variety of fungi and either cyanobacteria or green algae along with other tiny microorganisms. (Their scientific names vary based on the fungi species within them.) These tiny ecosystems survive on all kinds of surfaces, in all kinds of habitats, all over the world. Though they are not plants, the algae or cyanobacteria in lichens can produce sugars through photosynthesis to feed the fungi and the fungi in turn create a protective structure that gathers in the water and minerals needed for the photosynthesis, a symbiotic relationship. Some lichens are thought to be the oldest living organisms, settling in on the bare rock of the early planet.

This may be a “cructose” lichen with flakes on the surface that Wikipedia describes as “a bit like peeling paint.”

In November, the mosses (Bryophyta) at Watershed Ridge Park were thinning and less lush. But when I took a moment to focus on them, I could imagine the small community they host on each log. In her book, Gathering Moss, bryologist (a botanist specializing in mosses) and member of the Citizen Potawatomi Nation, Robin Wall Kimmerer describes moss as “the most ancient of land plants.” These tiny plants inhabit nooks and crevices worldwide and in doing so, Kimmerer compares their roles in the forest to the roles corals play in oceans – removing water impurities and hosting within their structures a myriad of tiny creatures necessary to the larger ecosystem in which they exist. Mosses also slowly help process logs into soil over decades and even rocks into sand over eons. I’d love to see the tiny creatures moving within these land-based “reefs” of moss, in the same way fish and eels inhabit an ocean reef. But I’ll need a magnification loupe and a lot more training before I can do that!

Mosses purify water and host tiny invertebrates that play their role within the life of a forest.

Off in the distance, at the eastern edge of this forest, a Red-tailed Hawk (Buteo jamaicensis) huddled over, apparently eating prey on the forest floor. Suddenly it flew up, skimmed quickly along the tree line and then headed out for the larger forest beyond the field.

A Red-tailed Hawk foraging just beyond the forest at the edge of the Eastern Field.

Years ago a farmer had dredged a ditch to drain the eastern wetland that stretches behind the eastern fields. To this day, the ditch carries water to another wetland. I turned to follow that stream back west to explore the area around and beyond that western marsh.

Water running through an old drainage ditch from the eastern to the west marsh.
Exploring the Meadow (H) Above the Western Marsh (I)
The slope above the eastern marsh, now covered with Showy Goldenrod

Walking back west, I arrive at a restored meadow that slopes down to the Western Marsh. During the summer, this lovely hill is covered in grasses and wildflowers. In this season, the field becomes an expanse of burnt golds and browns with the dried flower heads of various goldenrods. I’m learning to recognize wildflowers during their seeding season and this autumn, I mastered a few more. So here are four goldenrods in the sloping meadow as they appeared in the summer and as they look now, for those of you who share my interest in knowing the names of the plants and animals that share our local habitat with us.

As I stepped from the forest, a small orange butterfly popped up from among the goldenrods and sailed off into the distance. I pursued it, of course, but it never settled again. Luckily, I think I recognized it from its pattern, size and color. The small, orange and brown Eastern Comma (Polygonia comma) produces two generations each year and they look slightly different. The adults that emerge from logs or tree hollows in early summer have orange forewings, but much darker hindwings like this one:

The summer form of the Eastern Comma

The summer adults produce the winter adult that I saw at Watershed Ridge Park, which has similar patterning, but the hindwings are more orange. I think what I saw was a member of the winter generation which either overwinters or sometimes migrates. These butterflies feed on rotting fruit, tree sap or sometimes dung or carrion (!). So it’s not entirely surprising that I saw one fluttering above the goldenrod on a cool November day. Here’s a photo taken in November of a winter form Eastern Comma by a photographer just named “thoughton” at iNaturalist.org.

A few days later I was treated to a sight that I’m learning to anticipate in autumn – the dance of the Winter Crane Flies (genus Trichocera). These fragile little insects rise from dead grasses in cool weather and bob up and down in small mating swarms of mostly males. Females evidently only join in to find a quick mate and then lay eggs in the ground. The adults overwinter in logs or under leaf litter and emerge in the late afternoon of warm spring, fall and occasionally even winter days.

The blurred wings of Winter Crane flies dancing in a swarm in the the meadow above the marsh

With some persistence, I was able to follow one of these crane flies to where it rested for a few moments on a blade of grass. Now I could see the delicate legs and body of this cool weather dancer. Winter crane flies are harmless and completely ignore humans. In fact, as I walked on, I strolled right through a troupe of them that just continued bobbing up and down around me. Such a light-hearted performance to a human eye!

A closeup of the Winter Crane Fly as it rests on a plant stem
Extending the Western Marsh

The farmer who built the ditch running from the eastern marsh to the western hoped, I imagine, to drain both to gain more tillable ground. So the drainage ditch water used to quickly run on beyond the western marsh – but not anymore.

Back in October, the Fish and Wildlife Service helped Ben created an elegant plug for the ditch (J) which will keep water in the western marsh and let it rise to the level it likely obtained before the farmer’s ditch lowered the water level. The Wildlife Service also scooped out a shallow spillway that will allow the water to flow around the plug and slowly re-enter the ditch beyond the plug. That will keep the plug from being eroded if the water rises too high in the marsh. Look how attractive and useful this new barrier is! (Marsh to the right, ditch to the left.)

The large plug created to hold more water in the marsh also makes a path between two fields.
The Northern Field and Its Newly Created Wetland (K)

Until recently, I didn’t know this huge agricultural field was part of Watershed Ridge Park!

The long agricultural field off Lake George Road constitutes the northern section of Watershed Ridge Park

One afternoon in early October, my husband and I walked the long length of the north field to see if we could catch a glimpse of the north edge of the familiar western marsh. We walked carefully along the edge of the farmer’s field in order to preserve his crop and then headed into the woods. Just a few steps from the field, we were immersed in a lush, green area of the park that neither of us had never seen.

My husband, Reg, in the woods above the western marsh

A little more sorting our way through the undergrowth and we were rewarded by a lovely sight – the north side of the marsh with abundant tall reeds and surrounded by large trees. I can’t wait to see this area in the spring and summer!

The northern side of the western marsh in October

Ben thought of a third water project for this park. As part of the October work, he asked the Fish and Wildlife Service to design a new wetland in the northern field, near the ditch plug. By mid-November, it had already begun to collect runoff from the slopes above. Like the other projects, the goal of this hydrological restoration is to regain wetlands that were lost to tiling farm fields and ditching streams. The restored wetlands will capture runoff from the adjacent fields and filter the water. What a sight to see this wetland full enough to reflect an autumn sky!

New wetland in the northern meadow at Watershed Ridge Park

It appears that wildlife is already taking advantage of a new water source. Deer tracks encircled the water’s edge. No doubt other smaller animals and birds will make their way here once the wetland is surrounded by plant life, rather than the wide open agricultural field. But that change won’t take place for a few more years.

Deer tracks surrounding the new northern field wetland.
Making Watershed Ridge Park More Welcoming – for Us and Other Species!

Stewardship is a multi-faceted effort in our township: removing invasive species, mapping and surveying natural areas, monitoring vernal pools, sowing native seed, restoring native landscape, educating the public so they can more fully enjoy the nature around them, and so much more. And now Ben, our Stewardship Manager, has added the restoration of degraded wetlands to that list of tasks.

These pools, though relatively small now, will be a welcome addition to the parks, enriching the diversity of plants and animals around us. Water is just as crucial for other creatures as it is for humans. That’s why I always seek it out, muddy shoes and all, when I explore our parks. If they function as we hope they will, in the future butterflies, dragonflies and other insects will flutter and dash above these wetlands, courting, mating and producing young. Birds will dip their beaks on a hot summer day and the deer at the water’s edge will be joined by more nighttime creatures eager to slake their thirst in the darkness. Nature will find a warm welcome once the rolling landscapes sway and dance again with a rich assortment of native flowers and grasses .

And of course, with our new trails (and more to come), we humans can more easily be there too, enjoying that diverse natural world. Once the trails turn green, I hope you’ll find the time to follow these very accessible, gentle trails and perhaps venture beyond them to see all this remarkable park offers. It will grow only more beautiful in the years to come.

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 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.

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!

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.

A House Wren, beak wide-open in full song.

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!

An Eastern Towhee singing from a snag at Draper in 2019.

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.

Stony Creek Ravine Nature Park: Meadows A-Flutter and a Steep Forest with… Tulip Trees!

The west branch of Stony Creek winds through the ravine

Stony Creek Ravine Nature Park is a small park with big contrasts – between the sunlit, gently rolling meadow and the forest with large trees grasping the steep slope that plunges down to the creek stippled with sunlight below. It’s a fairly short walk, just in and out, for now. Eventually, we hope this elbow of a park will be joined to 208 spectacular acres to the east, now being acquired by our Parks & Recreation Commission. So I’d suggest you see it soon, so you can say you “knew it when!”

An Undulating Path through a Meadow of Fluttering Wings

The trail begins in a grove of trees at the end of Knob Creek Drive with its single parking space. A few years ago, Stewardship Manager Dr. Ben VanderWeide removed walls of invasive shrubs that crowded the edges of the trail into the park, obscuring the meadow. Now when I step into the park, the landscape is open to fields filled with tall flowers and sunlight. The meadow is an exuberant, dense tangle of native and non-native wildflowers –  and a lot of thistle! But the butterflies and bees make do with what they find and they are everywhere! So I periodically ventured out as far as possible into the shoulder-high plants to get a little closer!

Cam among the incredibly tall flowers and thistles of the meadow at Stony Creek Ravine.

Ben had reported seeing lots of Giant Swallowtails (Papilio cresphontes) on thistles at the park. Having seen them there in previous years, I was excited to look for them. But after a very hot week, they had evidently moved on to greener pastures. I only saw one at an unreachable distance across the meadow on my first visit. But since I saw many of them later at Charles Ilsley Park, here’s a photo of one to refresh your memory. Pretty impressive size, eh? They are actually the largest butterfly in North America!

Giant Swallowtail butterflies seem to be coming to our area in increasing numbers.

My birding friend, Bob Bonin, also saw something at Stony Creek in August that I only saw from a distance. I had a quick glimpse of a Snowberry Clearwing Moth (Hemaris diffinis) but couldn’t wade fast enough into the greenery to catch a shot of it. Bob generously shared his beautiful shot of one feeding on the last drops of nectar from a native  Bee Balm (Monarda fistulosa).  Clearwings lose some of the wing scales due to their hummingbird-style, hovering flight, leaving areas of their wings almost transparent. The yellow and black fuzziness of the  Snowberry Clearwing (Snowberry is one of its host plants) means that it’s often mistaken for a bumblebee – perhaps providing some protection from predators.

Native bee-balm also prompted a stopover by the Silver-spotted Skipper (Epargyreus clarus) which, according to Wikipedia, prefers to hang from the underside of leaves at night or on hot and humid days. Bee-balm, true to its name, attracts many native insects, including the ubiquitous native Bumblebees (genus Bombus).  (Click on photos to enlarge; hover cursor for captions.)

 

For the first time ever, I noticed European Honeybees (Apis mellifera) literally running around the tops of non-native Queen Anne’s Lace. I’d never before noticed this “busy bee” activity! They rush across each lacy blossom, perhaps quickly gathering nectar or pollen. Bee Culture, a beekeeping magazine, says that Queen Anne’s Lace produces the greatest amount of nectar in hot weather, so perhaps that’s what attracted them. Let me know in the comments if you have more info than I could find on this phenomenon. Here’s my amateur video of the bee race at Stony Creek Ravine.

It’s always heartening to see Monarch Butterflies (Danaus plexippus) in our parks, especially a female one sipping on Common Milkweed (Asclepias syriaca), its favorite host plant on which to lay eggs!

A female Monarch on Common Milkweed! Every year our parks do their part to protect this beloved species.

The Eastern Tiger Swallowtail (Papilio glaucus) is a generalist who can live in lots of habitats, from forests to meadows to urban areas. Its caterpillar can eat and grow on many of the trees in our parks, including Wild Black Cherry, Willows, Cottonwoods and Tulip Trees (see below!), but also on non-native plants like Lilacs. This adaptability means it’s thriving, and that made me glad as it paused so delicately to sip from the only tender part of a Plumeless Thistle (Carduus acanthoides).

An Eastern Tiger Swallowtail sips nectar from a non-native plumeless thistle.

Great Spangled Fritillary (Speyeria cybele) looked a bit ragged and uncomfortable one humid afternoon. I wonder if it had landed on too many prickly, bristly plants like the Plumeless Thistle! Most of the “spangles” are on the underside of the hindwings, so I’ve included an older photo to show them, since this butterfly clearly had no attention of feeding with its wings up.

A Great Spangled Fritillary on a very uncomfortable  plant!

Most of the silver spangles on a Great Spangled Fritillary are on the underside of the hindwings.

Red-spotted Purple (Limenitis arthemis) paused on non-native Queen Anne’s Lace (Daucus carota). It prefers rotted fruit or even dung and carrion, but occasionally it sips nectar from small white flowers like these, according to the citizen science website, butterfliesandmoths.org.  These butterflies sometimes produce two broods. The first caterpillars hatch and once half-grown, form a “hibernaculum,” an over-wintering refuge which for caterpillars usually involves a folded leaf and some spun silk to secure it. They then emerge in the spring and finish maturing.  According to Wikipedia, some of  the first larvae “are able to mature during the summer, so they emerge as the second brood [in] early fall,” but may have a tough time surviving winter cold. The prime condition of the butterfly below makes me wonder if it was from an early second hatch.

A Red-spotted Purple rests on a non-native Queen Anne’s Lace.

Some small butterflies also made the most of the late summer meadow. The  common and colorful Pearl Crescent (Phyciodes tharos) landed repeatedly on the path in front of me, as they often do. These very small butterflies can mate many times between April and November so we’re almost bound to see one on any summer walk  in our parks. And we’re also likely to see the non-native Cabbage Butterfly (Pieris rapae). I just love the sculptural look of the ventral (underside) of the wings on the one below. I think she’s a female since I can just make out the double wing spots on the dorsal (upper side); males have only one spot.

Right now, you’ll probably see a creature along the trail that looks like a butterfly with its black wings edged in beige, but is really the Carolina Locust (Dissosteira carolina). Despite seeing them every summer, I’ve never gotten a shot of their sudden flights from under my feet. So I can only show you what they look like once they land. But I’ve borrowed with permission a photo from an iNaturalist.org photographer, Joshua G. Smith, who held one in his hand to get a photo of the wing.

The Woods, the Deer Effect and a Bubbling Creek Below

A panorama of the woods where it begins to slope toward Stony Creek

The woods at Stony Creek Ravine Nature Park is full of big oaks and some beautiful native Tulip Trees (Lirodendron tulipfera)! These are not the shorter, heavy flowering cultivated trees that I grew up seeing in people’s yards. These mighty trees grow beautifully straight and tall often with few limbs once they reach 80-100 feet. In virgin habitat, they can grow to 160 feet and their girth can be as wide as 10 feet! According to Ben, there’s a huge one on the new piece of property that is planned to eventually connect with the existing 60 acre park. I hope someday I’ll be able to see it and show it to you here!

Tulip trees were once valued as timber because they grow straight and tall with few limbs until they are 80-100 feet tall.

Wild tulip trees (vs. nursery cultivated ones) only bloom at the top of the tree, so their glamorous flowers are rarely seen, but are rich with nectar. Their bark is ridged in an orderly pattern. The leaves have a unique, squared-off shape. And the graceful, seed-filled cones stay on the tree all winter only falling to the forest floor in the spring. I have never seen the flowers up close or the cones, so my thanks go to iNaturalist.org photographers kwilie and Sandy Wolkenberg for sharing the bloom and cone photos below. We’re lucky to see Tulip trees here because we are at the far north edge of their range. Can you tell I’ve found a new favorite native tree?

This slideshow requires JavaScript.

The forest floor beneath the impressive trees, though, is almost barren. The shade of course is very dense. But a huge problem is that, despite a limited hunting season in this park two days each week in from October to January, the deer are plentiful. As a result, few woodland plants reach maturity on the forest floor. Deer have no front teeth, so the stems left on the plants they graze are ripped and flattened as seen below. Rabbits, for instance, with their incisors, make a neat, angular cut. But hope springs eternal! Though most tulip tree seeds don’t survive, I found a small sapling that somehow had escaped the notice of the deer -so far.

As you hike down to the creek, more grasses appear. The creek’s moisture encourages some flowers, especially in the spring when the trees haven’t leafed out and more sunlight reaches the forest floor. In summer, the moist river bank is a  hangout for damselflies. One warm, gray afternoon,  I saw a female Ebony Jewel Wing (Calopteryx maculata) looking at me head-on from a fallen branch.

A female Ebony Jewelwing damselfly looked at me intently!

Her mate is a bit more glamorous, but I also like the elegant understatement of the female.

The west branch of Stony Creek burbles along, tumbling over rocks, slipping under fallen trees, catching glints of sunlight on its surface. And beneath the surface, small fish school in the shallows.

Small fish schooling in the clear water of Stony Creek as it runs through the ravine.

Deep in the woods on the far side of the creek, the shriek of a young Red-tailed Hawk begging to be fed grated upon my ears. Young hawks can repeat this harsh cry for 4 to 6 weeks! I know what adult hawks are dealing with, because in some years, a young hawk subjects my husband and I to their cries from the field next to our house! But hawks believe in tough love and eventually it gets hungry enough, I guess, to do its own hunting. Here’s my recording at Stony Creek Ravine Nature Park.

The youngster was nowhere in sight, but here’s a photo of one taken along Predmore Road near Lost Lake Park in 2017.

Red-tailed Hawk juvenile near Lost Lake in 2017

On a later visit, I was startled by a flash of huge wings, as a young hawk (I think!) flashed across the path in front of me and stumbled into a tree much too small for its size and weight. It wobbled back and forth on a thin branch for a few seconds. But before I raised my camera, it lumbered up into the air and soared off into the woods on the far side of the meadow. As far as I could tell this “desperate escape” was caused by the harassing pursuit of a single Blue Jay (Cyanocitta cristata) – hardly the behavior of an adult hawk!  Like a lot of adolescents, this young bird just needs a bit more time to grow up.

Back Up in the Meadow – Baby Birds and a Fun Baby Insect

It’s a steep climb out of the ravine, up through the woods to the path and the sunlit meadow. Back on the trail,  I noticed out in the meadow a few fledglings learning to make their own way in the world. A juvenile Eastern Bluebird (Sialia sialis) still sported the fledgling’s dappled chest, a field mark common to other members of the thrush family. It had landed high on the bare branch of a snag to survey the field, looking quite confident that it could survive on its own.

A Bluebird fledgling out on its own and surveying its world.

A little Song Sparrow (Melospiza melodia) popped up out of the greenery, looking like a plush toy! Donald W. Stokes’ Guide to Bird Behavior (Vol. 1) points out that a good field mark for juveniles is that their tails are about half the size of an adult Song Sparrow. Next spring, this little sparrow will look for a nesting site within its “song neighborhood,” i.e. close to the the place where adult birds sing the songs that it heard and memorized as a nestling. According to this Cornell Ornithology Bird Academy website, juvenile male sparrows need to practice for several months before they can sing their repertoire perfectly – sort of like babies babbling before talking.

A Song Sparrow fledgling learns its song repertoire from neighboring adults while still in the nest.

Far out in the meadow, I saw a hard-working male American Goldfinch (Spinus tristis) traveling about with a juvenile. Male Goldfinches do most of the fledgling feeding because the females are busy with a second clutch of eggs. Goldfinches wait to breed until mid-summer when thistles provide them with fluffy pappus (downy plant material) to make an almost water-tight nest lining. Then they feed their young with partially digested thistle seed. I could hear an insistent fledgling calling to be fed and could see the adult male flying to meet it. Each time, the two of them disappeared into the greenery for a meal. I moved further into the dense undergrowth, trying to see the adult feeding the youngster. Finally, the fledgling, alone again, came out onto a bare tree stem and diligently chewed at its tip. My best guess is that this behavior is a way to practice stripping hulls from the seeds that make up almost all of a goldfinch’s diet. But I’m not sure, though I’ve seen two young goldfinches do this in the last week!

A juvenile Goldfinch gnaws the end of a stem, perhaps practice for removing hulls from seeds in the future.

Out in the field, the adult male Goldfinch hopped about on a thistle, filling his beak with seed to share with the youngster. I believe the thistle he chose  is again Plumeless Thistle.  At least it appears to feed the birds and butterflies!

The birds will be able to enjoy a treat before too long, because a big, energetic patch of  American Pokeweed (Phytolacca americana) with its Dr. Seuss-style color scheme has appeared along the trail! The green berries in the photo below will gradually turn white and then deep purplish-black. When ripe, they are much beloved by birds, particularly the Gray Catbird, Brown Thrasher, Northern Cardinal and the Northern Mockingbird, according to Wikipedia. However, they are highly toxic to most mammals, including us humans! So admire them,  but no snacking, not even one!

On the way back to the car, I spotted one of the largest and  most graceful nests of Eastern Tent Caterpillars (Malacosoma americanum) I’ve ever seen. These gregarious caterpillars head out each morning to forage together and return to their tents at night. The tents are added to each day before they leave, so they have multiple layers. As a result, the caterpillars can go to different parts of the tent for heating or cooling.  Though their feeding can defoliate trees, they cause little permanent damage and the trees generally re-leaf once they’re gone.

This tent is almost empty probably because in the morning, the Tent Caterpillars leave en masse to find food together.

My forays deeper into the meadow left me with socks covered in burs and sticky seeds. So on my way back to the car, I stopped at the beautiful bench commemorating the Kezlarian’s generosity toward this park. Along with the burs, I plucked a small caterpillar from one sock and set it on the bench. To my delight, it quickly began scooting around on the granite at a rapid pace. I laughed out loud! It was an inchworm! I looked them up when I got home and discovered they are caterpillars of the large and diverse moth family, Geometridae. Here’s the 30 second video I took of it that still tickles me. (It should have some cartoon music in the background, but again, I’m a complete beginner at videography!)

By the way, after filming, I let it climb on a dry leaf, carried it to a nice green one and wished it well.

The Persistence of Nature as a Challenge to Care

Water flows around a bend in Stony Creek Ravine Nature Park.

Places like Stony Creek Ravine Nature Park strengthen my hope when life feels challenging. The intense July heat – reportedly the hottest July in history worldwide! – finished the bloom of many flowers that might have lasted longer in a normal year. But honey bees rush about on less nectar-rich blooms, trying to gather their much-needed supply of pollen to feed the young  or  the nectar for making honey to feed the over-wintering colony. Some butterflies make their way across great distances  in unpredictable weather, seeking out available nectar to feed themselves and suitable host plants for their eggs. Young birds exercise their new skills, learning within weeks how to forage on their own in a landscape shaped by the changing climate. The glimmering creek down in the shadows of the forest rises and falls with the rainfall, but, for now,  flows on.

This same persistence, I think, also challenges us to do what we can to cool our planet and return to the patterns that nature has bequeathed to us through eons of experimentation. We owe it to the wildflowers, bees, butterflies – all of the natural world that supports us – to shape our lives not just to our human needs, but the needs of all the living beings that share this little blue planet with us. The township stewardship program is working on that, I’m working on that – and I bet you are, too. Let’s press on!

Draper Twin Lake Park (Eastern Portion): A Rainbow of Butterflies, Fledglings Foraging and a Golden Prairie

The Northern Prairie on the east side of Draper Twin Lake Park in July

In June, the prairie pictured above at Draper Twin Lake Park was a sea of white Yarrow (Achillea millefolium) and Ox-eye Daisies (Leucanthemum vulgaris) dotted with golden Sand Coreopsis (Coreopsis lancelolata). Today, as you can see, it is carpeted in the bright yellow of Gray-headed Coneflowers (Ratibida pinnata). Such a remarkable transformation in only one month! (You’ll want to park near the small garage at 1181 Inwood Road to visit the east side of Draper Twin Lake Park.)

Last week Ben VanderWeide, our township’s Natural Areas Stewardship Manager, had to mow large sections of the golden prairie to prevent seed production in the invasive and aggressive Spotted Knapweed (Centaurea stoebe). We hope the mowing will reduce knapweed abundance and give native plants a competitive edge as they continue to fill in throughout the field. The prairie, though, is still a beautiful sight since it signals the return to our parks of graceful native wildflowers and grasses that sway in a summer breeze.

Native Wildflowers Invite An Abundance of Butterflies

The more our prairies are restored, the more they attract a whole panoply of colorful butterflies. Giant Swallowtails (Papilio cresphontes) seem to be everywhere this summer. It may be that our hot July has encouraged more of them than usual to migrate up from the south to breed. And once they arrive, our prairies provide generously for them. This huge butterfly flutters constantly while feeding, though it floats elegantly between flowers, beating its wings briefly and then gliding along.

The Giant Swallowtail flutters constantly while feeding though it is an elegant flyer.

An Eastern Tiger Swallowtail (Papilio glaucus) swooped out of a patch of Plumeless Thistle (Carduus acanthoides) and soared across the prairie.  I believe the blue spots at the bottom of the wings mean it was a female. I never noticed before that they have such a fancy striped body!

Red-spotted Purples (Limenitis arthemis) love open areas on forest edges, which makes the prairie at Draper Twin Lake Park a perfect habitat. Their blue/black appearance makes them easy to confuse with Black or Spicebush Swallowtail butterflies. The big difference is that all Swallowtails are so called because of the characteristic drooping points at the bottom of the hind wings. Red-spotted Purples have scalloped hind wings but no “swallowtails.” (Click on photos to enlarge; hover cursor for captions.)

A small Viceroy (Limenitis archippus) butterfly landed on a Queen Anne’s Lace flower (Daucus carota) in front of the birding group.  Mike Kent, a fellow birder, slowly and gently extended his finger and this little one climbed right on. A few moments after this photo, it started “tasting” his skin with its long proboscis! Quite a magical moment!

A few smaller butterflies and other flying insects are fluttering across the prairie this summer. The Eastern Comma (Polygonia comma) is an early spring arrival and looks a bit battered by now.

The tiny white Carrot Seed Moth (Sitochroa palealis) is a non-native from Europe who, consequently, sips on many non-native European plants like Queen Anne’s Lace or here on non-native Spotted Knapweed. Thanks to Dwayne Badgero on the Butterflying Michigan Facebook page for identifying this one for me.

The Carrot Seed Moth is a non-native who feeds largely, though not exclusively, on non-native plants like the spotted knapweed shown here.

I saw the lovely American Copper (Lycaena phlaeas) on the Draper prairie earlier in the season, but never got a shot.  The photo below is one I took at Cranberry Lake Park.

I saw an American Copper on the prairie, but this photo was taken at Cranberry Lake.

This juvenile male Widow Skimmer (Libellula luctuosa) has a faint white band on its wing which will get bolder as it matures. Also, its abdomen will slowly develop a white covering. The adult females have no white band and keep the darker abdomen with the golden stripes.

Hard-working Bird Parents are Busy Feeding the Young

On entering the eastern side of Draper Twin Lake Park last Sunday, my husband and I heard a clamor in a snag (standing dead tree) on the eastern edge of the field. A large band of Barn Swallow youngsters (Hirundo rustica) were hanging out together, a few still being quickly fed by their parents.  Stokes’ Guide to Bird Behavior (Vol. 2) explains. “Often groups of juveniles from first broods gather into flocks and feed and perch together.” We counted over 20 in or near the snag at the same time. Later that same week, Ben reported having 50 or more Barn Swallows flying right next to him and his mower as he worked on the prairie. Very social birds! Young Barn Swallows have shorter, rounder tails, rather than the longer, deeply forked ones of their parents. (Use pause button if time is needed for captions.)

Two larger fledglings appeared on the trail between the marsh and parking area. They hopped along the edge, pecking at the earth in a desultory fashion, but repeatedly stared up longingly into the trees. We didn’t recognize them at first. Then my husband noticed a sharp clicking in the trees and we suddenly spotted an adult Brown Thrasher (Toxostoma rufum) moving stealthily through leafy branches overhead. Aha! These were two juvenile Thrashers out practicing their foraging skills! The telltale field marks are the light colored heads, scalloped backs and gray (rather than yellow) eyes.

Brown Thrasher adults are notoriously hard to see. On Sunday, the adult stayed hidden in tangled bushes, vines and leafy branches, as Thrashers most often do. But after a frustrating few minutes, the annoyed adult emerged and demonstrated his displeasure at our proximity to its young with a yellow-eyed glare and a wild tail display!

The adult Brown Thrasher show his irritation at our presence with a fantastic tail display.

In spring, high in the treetops, Brown Thrasher males sing their wildly variable song, made by mimicking Flickers, the Tufted Titmouse, the Cardinal and others. And that click we heard overhead on Sunday was an alarm/warning call that both Cornell Lab of Ornithology and the Stokes’ Guide describe as sounding like a smacking kiss! And it does! Listen to both the creative chaos of the song and smack! call at this Cornell link.

Restoring Our Natural Heritage in So Many Ways

The hard work of Ben VanderWeide and his crew in clearing, seeding and tending the natural areas of our township is paying off magnificently. Just as expected, the wildflowers and grasses flourish when given the opportunity. And as they return to their former glory, back come the butterflies, the grasshoppers, the dragonflies, and the bees. And after them, we hope, may come more of the prairie birds that used to live with us, like the Eastern Meadowlark (Sturnella magna), Henslow’s Sparrow (Ammodramus henslowii), and perhaps even the long absent Northern Bob-White (Colinus virginianus). Already less common prairie birds, like the Savannah Sparrow  (Passerculus sandwichensis) which I saw earlier this summer at Draper Twin Lake Park, are looking for mates as they ride the stems of prairie plants.

Ben’s stewardship program is also helping to restore bird populations and providing citizen science data by setting up nesting boxes in two parks and along the Paint Creek trail. The volunteers who monitor these boxes watched multiple broods of Eastern Bluebirds, Tree Swallows, House Wrens and Black-capped Chickadees go from egg to fledgling just this year.

And let’s not forget us humans. We’re also out in the our parks more these days! As Ben, his crew and volunteers restore our colorful prairies, people come out to enjoy the natural areas that township residents have been committed to preserving and protecting for many years. Our birding group has grown consistently year by year, exploring and recording bird sightings for Cornell’s eBird citizen science program even on the coldest winter, the rainiest spring and the warmest summer mornings. The schedule is under “Events” at the top of the page. Please come join us! Ben will even lend you binoculars. We’re restoring ourselves as well while we preserve, protect, and delight in our small green corner of the world.
