Stony Creek Ravine Nature Park: BUTTERFLIES! Oh, and Birds and Blossoms, too…

The Northern Wetland Meadow at Stony Creek Ravine Park has no shallow pools now, but is lush with plant life.

A kaleidoscope of dancing butterflies grabbed my attention time and again as I visited Stony Creek Ravine Nature Park in August.  Oh, yes, fledgling birds also whisked about in the dense greenery, accompanied by adult supervision, learning to feed or begging to be fed. And patches of glorious orange or blue flowers emerged among the tall grass.

But it was the butterflies that stole the show for me as they hovered, floated, sailed and finally settled on blossoms or perched on a leaf along the trail. On glamorous wings – or sometimes tattered ones –  they danced summer to a glorious finale. Come see.

The “Corps de Butterflies,” Costumed in a Rainbow of Colors, Take the Stage

Bands of colorful vegetation in the moist, northern restoration meadow attract skimming swallows, darting dragonflies and floating butterflies

Every year now I wait for the late summer arrival of the Giant Swallowtails (Papilio cresphonte), the largest butterflies in North America (6-7 inch wingspan!). This prima ballerina of the butterfly corps  used to only breed in the south. Many researchers seem to think that most Giant Swallowtails still migrate south in the autumn. However, as the climate has warmed and prevented September frosts, they have expanded their range, establishing some small populations in lower Michigan. Whether they are breeding in our area or just nectaring before heading back south, I’m always glad to see them.

A Giant Swallowtail is the lead dancer in August.

Several butterflies showed up on summer’s stage with torn wings. I’ve wondered if that could be a result of being blown into harm’s way by the winds that accompany summer thunderstorms. Or perhaps the late bloom of goldenrods this year meant that butterflies fed more on prickly thistles. The ragged Eastern Tiger Swallowtail (Papilio glaucus) below seemed to be feeding and flying reasonably well, despite its ravaged wings. I hope it had already mated since shape is important in butterfly courtship!

A badly damaged Eastern Tiger Swallowtail seemed to be feeding naturally on thistle.

Most Eastern Tiger Swallowtails  took the stage in August dressed in their best. Notice the long hairs on the abdomen of the one below. I learned recently that the scales on a butterfly’s wings are actually flattened hairs.  According to a study by Judith H. Myers at the University of British Columbia, it’s possible that the long hairs, sometimes called “scent scales,”  are used to spread pheromones in flight during the breeding season. The pheromone receptors that pick up scent are located in both male and female antennae, though scent is less important than color, shape and movement when most butterflies are courting .

This Eastern Tiger Swallowtail has long hair on its abdomen which may help distribute pheromones when attracting a mate.

Another butterfly “long hair” comes in a tiny package, the Common Checkered-Skipper (Pyrgus communis). My husband spotted this tiny male whose wingspan is only about .75 to 1.25 inches. We’ve probably missed it before because it’s so small and looks nondescript when fluttering erratically along the path. But when it stops, wow! Its thorax is dark blue-gray and the males are not only fuzzy like most skippers; they have long bluish “hairs.” A handsome little guy! Evidently the female’s thorax is a much less glamorous dark brown. According to the Butterflies of Michigan Field Guide by Jaret C. Daniels, this tiny butterfly is  most common in the central and southern states but regularly  expands its range and is seen in our region in late summer and fall.

This male Common Checkered-skipper has long scent scales that look like hair.

I was delighted to finally see a restless Great Spangled Fritillary (Speyeria cybele) as it fluttered from sunlight to shade and back again along the entrance path. What a costume! The dorsal (upper) side of its wings is patterned in orange and black, but its ventral side flashes with silver spangles! The females lays eggs even into September. Their caterpillars overwinter and start eating violet leaves in the spring, according to the Butterflies of Michigan Field Guide.  

The Great Spangled Fritillary appears in July, but lays its eggs in September.

Spicebush Swallowtail (Papilio troilus) added its dark beauty to the butterfly ballet. It’s very tricky to discern the differences between dark swallowtails. If you need help like I do, I recommend the website at this link which compares the female Black Swallowtail, the black morph of the Eastern Tiger Swallowtail, the Spicebush Swallowtail and the Pipevine Swallowtail. Whew! It always takes me a while to puzzle them out! I also get help from the good folks at the Michigan Lepidoptera Facebook group.

The Spicebush Swallowtail has a blush of blue on its hindwings.

The ventral (lower) side of the Spicebush’s wings have two rows of orange spots like the Black Swallowtail, except that one spot on the inner arc is replaced by another blush of blue.

I finally got a look at how the little Pearl Crescent (Phyciodes tharos) came by its name. If you look closely at the lower edge of the hindwing, there’s a tiny whitish crescent shape in one of the boxes there. In the photo below, I brightened the spot and created a small red marker so you could see it, too. It’s a subtle field mark, for sure!

The red marker shows the white crescent for which the Pearl Crescent is named.

And here’s how the Pearl Crescent appears from above. You’ll see these little butterflies on any walk you take in our parks from June to October. I like knowing its name; it makes a walk more companionable somehow.

The tiny Pearl Crescent skips along the paths in our parks all summer long.

Of course it’s the season for Monarchs (Danaus plexippus) and though they seem less plentiful this year than last, a goodly number still stroke a few wingbeats and glide over the fields. Here’s a sampling of three at Stony Creek Ravine Park – a male settling along the path, one in flight toward a withering Bull Thistle (Cirsium vulgare) and what I think was a female on Common Milkweed (Asclepias syriaca). [Click on photos to enlarge; hover cursor for captions.]

Another set of dancing wings joined the choreography.  With a zing, a dive and a pause in mid-air (à la Baryshnikov), a fierce and glorious dancer,  the Green-striped Darner (Aeshna verticalis) came on the scene. Darners are big, more than 2.5 inches long,  with bulky thoraxes and long abdomens. Add the helmet-like appearance of their giant eyes which meet at the top of their heads, plus their ability to hover,  and in flight they have a remarkable resemblance to a tiny helicopter! These skillful predators feed on all kinds of insects, even meadowhawk dragonflies and damselflies. The northern fields were a-buzz with them at the park last week!

A Green-striped Darner patrolled along the path as we walked north at the park.

Of course, many other insects – bees, small butterflies, and smaller dragonflies – fed and bred in Stony Creek Ravine Nature Park in August. Here are a few more modest members of the winged corps.

While following the Spicebush Swallowtail, I glanced down at some movement in the grass and found a tiny grasshopper. A wary, or perhaps inquisitive, nymph of what may have been a Red-legged Grasshopper (Melanoplus femurrubrum) peered at me through two blades of grass! My expert resource person, Dr. Gary Parsons of the Michigan State University’s Entomology Department informed me that not only are the nymphs of this genus very similar,  but within each species the nymphs have many variations of color and pattern. Nymphs don’t have fully-formed wings,  so it will have to save its balletic leaps for a bit later in the summer finale.

This  nymph, possibly of a Red-legged Grasshopper, looked straight at me as if to say, “Verrrry interesting!”

Once it saw my camera, it twitched around the side of the grass stem and dangled there for a few minutes by its front legs. At first, the move made it difficult for me to find the nymph among the grass stems. I wondered if this was a camouflage technique; it did resemble a dangling wilted leaf as my eyes searched the ground. But eventually it must have decided I was not a threat and hopped back on the stem. A lovely few moments with a young creature.

A tiny Wood Frog (Rana sylvaticus), barely visible under a leaf, also missed the whole dance above as it made its way to high ground. As the nights cool, Wood Frogs look for leaf litter where they can produce inner anti-freeze and hibernate, frozen solid, until spring.

A tiny Wood Frog, perhaps an inch long, tried to blend into the brown grasses on the trail, keeping perfectly still.

Oh, Yes, Birds too!

My walks in our parks so often provide serendipitous moments for me. I’d been craning my neck to watch Barn Swallows (Hirundo rustica) swooping overhead, trailing their long, forked tails and wished aloud that one would perch for a photo. Just then, as my husband and I rounded a curve at the bottom of the Lookout Hill, we were gifted with this wonderful sight!

A selection of about 25-30 Barn Swallows perching on the fence around the southern restoration area below the Lookout Hill.

Dozens of Barn Swallows lined up on the fence with others perching on stalks in the tall plants within the fence line. What a surprise!  According to the Cornell Ornithology Lab, older siblings from earlier Barn Swallow broods often assist their parents in feeding the later broods of nestlings. The parents sometimes even get help from unrelated juvenile barn swallows. On the other hand, unmated barn swallows occasionally attack the young of a mated pair in hope of mating with the female! Nature in all species, I expect, has its good instincts and its bad ones.

One morning when I arrived, a large Pokeweed plant along the entrance path near Snell Road was aflutter with juvenile Cedar Waxwings (Bombycilla cedrorum). I could hear their high, piercing calls, but it took a while until one of the youngsters settled on a tree branch nearby for its portrait. Only the mask and the yellow tip of its tail identified it for me, because of its mottled breast and gray overall appearance.

A juvenile Cedar Waxwing can be identified from its mask and the yellow bar at the end of its tail.

A watchful older Waxwing perched in a nearby tree keeping an eye on the rowdy juveniles enjoying the Pokeweed berries and each other’s company. This one appears to be a first year waxwing because its upper wing is solid gray-brown and is missing its red dot; perhaps it has begun the annual molt because its mask and crest look incomplete. Its disgruntled look made me smile, thinking maybe babysitting juveniles was not its favorite assignment!

An older Cedar Waxwing keeps an eye on a troupe of rowdy youngsters.

An Eastern Kingbird (Tyrannus tyrannus) sitting nearby looked over at the hubbub but generally ignored the Waxwings. Since Kingbirds are insectivores during the summers here, there was no need to compete for the Pokeweed berries. In the winter, however, when they fly all the way to the Amazon, they join a variety of flocks and eat only fruit.

An Eastern Kingbird watching the young Waxwings.

At the top of the Lookout Hill, a pair of House Finches (Haemorhous mexicanus)- either females or juveniles which look just like their moms – were avidly scraping insects or insect eggs off the stems and leaves of a tree that clearly had already hosted a lot of caterpillars or other small bugs. The leaves were riddled with holes! I’m guessing that House Finches learn at a young age that leaves with holes mean FOOD!

These House Finches seemed to be making most of an insect-scavenged tree at the top of the Lookout Hill.

Nearby a juvenile Rose-breasted Grosbeak (Pheucticus ludovicianus) looked a bit forlorn after it settled in a tree on the Lookout Hill. I didn’t identify this little bird as a Grosbeak until local birder extraordinaire Ruth Glass helped me out. Grosbeaks are now starting their migration to the Caribbean, so I hope this little male will soon be ready to take on his long flight across the country and the ocean beyond.

A juvenile Rose-breasted Grosbeak might mature a bit more before it begins its long migration to the Caribbean.

Our stewardship manager, Dr. Ben VanderWeide, mowed a path from the bottom of the Lookout Hill, going west, south, and then west again to connect to the older section of the park where the West Branch of Stony Creek runs through a beautiful ravine. As I approached the woods over the ravine, I kept hearing a plaintive Eastern Wood-Pewee (Contopus virens) in the woods but never got to see it. But I did see this little flycatcher, the Eastern Phoebe (Sayornis phoebe) perching on a bare branch looking a bit rumpled. I wondered if it was a juvenile, though I can’t tell from its plumage.

An Eastern Phoebe looking a bit ruffled along the trail from the new section into the older ravine section of Stony Creek Ravine Park.

On a cool morning on my last trip to the park, a molting European Starling (Sturnus vulgaris) appeared to be warming its breast high in a bare snag along the entrance trail. During the summer breeding season, these non-native birds are dressed in sleek black with iridescent blue-green overlays. Their beaks turn yellow then, too. But now, as fall arrives, they change into their winter garb. Their beaks turn dark and the feathers on their backs and breasts become covered with white spots. This one was already well along in the process.

This European Starling is in the process of molting to its spotted winter feathers and dark beak.

And Last But Certainly Not Least, the Trees and Plants that Make It All Possible!

Clearly, butterflies and birds grace our parks because these natural areas are rich in nutritious native food and abundant shelter for both adults and their young – the fledglings and the caterpillars. So let’s spend the last few minutes with perhaps an under-appreciated but vital element of any habitat – the native plants and trees that provide nesting space, nectar, pollen, seeds, nuts and most importantly, oxygen for all creatures – including us!

Wildflowers First

Begin by looking at that glorious patch of rare, native Black-eyed Susans (Rudbeckia fulgida) pictured above. These are not the ordinary Black-eyed Susans (Rudbeckia hirta) which gardeners  sometimes choose as annuals, or the native, but short-lived Rudbeckia hirtas that thrive in so many habits, including dry prairies. These bright yellow flowers at Stony Creek Ravine Park are a separate species of wildflower that prefers wetlands and is a long-lived perennial. They’re also the species used to create many varieties of cultivars used in landscaping. I’m so glad Ben shared his photo and his enthusiasm on finding these special plants – and for the photo. I was unaware that a wetland “Susan” even existed!

Ben also discovered a lovely patch of Great Blue Lobelia (Lobelia siphilitica) growing near the edge of the woods in the north area of the park.  It too is a lovely wetland plant and often hosts our native, long-tongued Bumblebees. Though I’ve seen small patches and single stems of these blue flowers in other parks, Ben’s discovery is the biggest patch I’ve seen.

Several fields in this new section of the park are under cultivation by a local farmer until the park restoration can begin more fully there. At the edge of one of them is a lovely stand of bright pink Swamp/Rose Milkweed (Asclepias incarnata). These wetland milkweeds host Monarch butterflies, of course, as well as swallowtails, some frittilaries, native bees and skippers. But, good news, deer don’t eat milkweeds!  So if you have a moist garden, give these some thought.

I love Blue Vervain (Verbena hastata) for its upright purple plumes, but it is also remarkably productive in the food web. Its nectar provides nutrition for a wide variety of native bees, small butterflies and moths. According to the Illinois Wildflowers website, the seeds also provide nutrition for many birds, including Cardinals, Swamp Sparrows, Field Sparrows, Song Sparrows and our winter visitor, the Dark-eyed Junco. Beauty for the eye and utility for the food web – a great combination!

Blue Vervain’s plume provides lots of sustenance to birds and pollinators.

Oh, and remember those young Cedar Waxwings jostling around in the greenery? What attracted them most were Pokeweed berries (Phytolacca americana). Lots of other birds love them as well, including Cardinals, the Gray Catbird and the Brown Thrasher. The fruits,  which are green now,  turn dark purple when mature. On those pink stalks, the plants look as though they should be somewhere in the tropics! Mammals however, like we humans and our pets,  should not partake of any part of this toxic plant. It looks luscious but it has evolved to be eaten by birds and not by any members of mammalia, our class of animals – which is frustrating because the fruits looks so tempting!

Here’s a quick tour of some of the other native wildflowers sprinkled throughout the meadows at Stony Creek Ravine providing sustenance to wildlife.

And Now, A Few of the Mighty Trees at Stony Creek Ravine Nature Park!

The Ravine and the West Branch of Stony Creek, for which the park is named

Though the fields of Stony Creek Ravine Nature Park are alive with pollinators, blossoms and birds, the lush woods that embrace them are equally impressive. In the park’s far western section, the West Branch of Stony Creek shines silver as it runs through the steep terrain of the heavily treed ravine for which the park is named. Along  its slopes and on the trail high above the creek, many species of trees  compete for sunlight while sharing nutrient resources through the fungal networks underground.

Some trees go to great lengths to reach the sunlight along the trail above the ravine.

One tree I look for every time I visit the ravine section of the park is a lovely American Beech (Fagus grandifolia) just over the edge of the slope near the end of the ravine trail.  Its satin-like bark makes me wish I could reach out and touch it.  According to the University of Michigan’s Michigan Flora website, a non-native scale insect (Cryptococcus fagisuga) can leave wounds in its bark that make them vulnerable to a deadly fungus (Nectria coccinea) which causes Beech Bark Disease, only recently discovered in Michigan. We need to protect these glorious native trees which provide so much food for wildlife and so much beauty for us.

A large beech tree stands precariously over the edge of the Stony Creek Ravine.

On the day the Wednesday bird group visited the park, Ben pointed out a huge Bur Oak (Quercus macrocarpa) next to the trail. This huge tree has merged three very large trunks. Each on their own would constitute a mighty oak!

The empty “mossy cup acorn” of a Bur Oak.

Bur Oaks make what the Michigan Flora website calls “mossy cup” acorns. This tree may live for many years to come. Not terribly shade tolerant, it is exposed to sunlight on the edge of  the woods near the trail and the long wetland along the entrance trail probably provides the amount of moisture it prefers. Ah, the stories this old tree could tell!

An old Bur Oak south of the trail that leads to the Ravine.

On the tree line between the northern restoration section and the western meadows is an old White Oak (Quercus alba) that demonstrates how location effects the growth of trees. In the open sunlight, surrounded by little competition, the oak has basked in sunlight for many years and spread it branches out instead of up, into a lush, wide crown. What a sight!

An old White Oak spreads out in the uninterrupted sunlight next to the north restoration area.

In the forest to the north last fall, Ben and I visited a huge Wild Tulip Tree (Liriodendron tulipifera) that used its energy to grow tall, reaching up into the sunlight. Maybe that’s why its lovely yellow flowers only bloom high in the crown. Here’s the photo of it that I posted previously in the blog – just another example of the trees waiting to be explored in the forests beyond the fields.

The Legacy Within Us

My husband at dusk just being with nature

I recently enjoyed an On Being Podcast interview with naturalist and environmental journalist, Michael McCarthy. He shared an insight from evolutionary psychology, namely that for 50,000 generations we humans were simply part of nature. For all that time, before we settled down to farm, we experienced all the challenges other creatures face in trying to survive in nature. Or as he put it “we were wildlife, if you like.” As a result, McCarthy contends, even now what we experienced, what we learned during those millennia is still in us, still making us feel at home in the natural world.

Maybe that explains why so many of us experience peace when we’re in places like Stony Creek Ravine Nature Park. On some level, we’re at home in natural areas in a way that even our cozy firesides cannot quite duplicate. Standing on the Lookout Hill at Stony Creek Ravine Nature Park, I look out across moist wetlands and meadows to the encircling wood and just let go, become part of the scenery, embedded in its beauty. The swallows dip and rise, the butterflies float from stem to stem, the woods stands dark and mysterious, the creek at the western edge sings its songs over the rocks – and I’m just part of it all.

I imagine it’s that kinship with nature that motivates you and I to learn about and care for our badly damaged world. And it’s probably that kinship which pushes us out the door and into a park on a cold fall morning or just before dark on a summer night to once more savor our connection to the natural world. Michael McCarthy put it like this: “… there is a legacy deep within us, a legacy of instinct, a legacy of inherited feelings, which may lie very deep in the tissues…we might have left the natural world, most of us, but the natural world has not left us.”

And what a blessing that is! Our task, our calling now is to continue restoring and preserving the natural world for our children and grandchildren. By honoring that legacy within, we can hope to insure that future generations will also be able to breathe deep and feel the freedom and peace that nature so generously provides to us.

Charles Ilsley Park: The Solace of Nature, Despite Windstorms and Heat

On June 10, a powerful windstorm with 90 mph winds flattened half of a small woods along  our driveway, dropped and split trees around our yard and dramatically thinned and damaged the larger forest canopy that surrounds our house. As soon as that massive fist of wind plowed its way north, the heat descended, staying around 90 degrees for two weeks or so. As a result, my forays into Charles Ilsley Park to monitor nest boxes became my only opportunity to see nature largely unscathed.

Twice each week, I hike out to see if eggs in the nest boxes have hatched, if nestlings are becoming feathered, if fledglings have ventured forth into the big world outside. So in this blog, I’ll share in one virtual hike what I saw at Charles Ilsley Park before the windstorm and during my semi-weekly monitoring walks. Glad you’re accompanying me.

On the Path Heading In

The trail into Charles Ilsley Park

Local birder extraordinaire, Ruth Glass, alerted my photographer friends Joan and Bob Bonin and me to the presence of a Yellow-throated Vireo nest (Vireo flavifrons) near the parking lot. I searched the branches on two different trips and never spotted it. But luckily, Bob got a great photo of this lovely migrator on its nest. The nest is such an art piece, as you’ll see below. It’s usually made of bits of bark, grasses, dry leaves; this one is decorated with lichen as well – and all nicely packaged with spider silk! The males and females of this vireo look alike (monomorphic) and both genders incubate the young. Ruth reported that she saw the female in the nest being serenaded by the male nearby. But I have no way of knowing which gender Bob saw for this photo. Sigh…wish I could have seen this bird in its nest – but I’m  so glad Ruth and the Bonins did!

Both male and female vireos incubate their eggs. Photo by Bob Bonin with permission.

An Eastern Wood-Pewee (Contopus virens) landed in the big oaks along the entrance trail. It appeared to have a bit of nesting material in its beak – probably a piece of lichen. According to Cornell Lab of Ornithology, this little flycatcher’s “lichen-covered nest is so inconspicuous that it often looks like a knot on a branch.”

The Central Prairie – Flowers Blooming and Boxes Filled with Baby Birds

Blooms, Butterflies and Beetles

On my early visits, purple spires of Wild Lupine (Lupinus perennis) peeked out of the grass here and there in the central and western prairie. Lupine once established can tolerate intense sun and dry soil, so it does well in prairies. When I came back later in June with the birding group, some of the lupines had made fuzzy seed pods that I’d never noticed before!

By the time the pods had formed on the lupine, a summer bloom, Lance-leaf Coreopsis (Coreopsis lanceolata) had emerged in the central prairie. Coreopsis bursts forth in golden composite blooms. The sunshine-yellow, ragged “petals” are really ray florets that surround the tiny disc florets at the flower’s center. These florets are tiny individual flowers, part of the plant’s reproductive structure.

Lance-leaf Coreopsis is a composite, a bloom formed by two kinds of florets. The center is a cluster of disc florets that provide nectar and pollen, surrounded by ray florets that look like petals.

According to one of my fave wildflower websites, Illinois Wildflowers, it also provides both nectar and pollen to a wide variety of floral visitors – lots of native bee species as well as beetles, and butterflies. One of the birders spotted a Baltimore Checkerspot (Euphydryas phaeton) sipping nectar avidly from a Coreopsis. Unlike most butterflies, its caterpillar overwinters. According to Wikipedia, in late summer or fall, the caterpillar stops eating, spins out some silk and wraps itself in a pre-hibernation web on a plant.  Before winter begins, it will exit the web, and spend the cold months hibernating in dead grass or leaf litter until pupating in the spring.

A couple mid-summer wildflowers appeared later in June. Hairy Beard-tongue (Penstemon hirsutus) produces tiny hairs on every surface – leaves, stems, even petals. Clearly this wildflower knows how to protect itself from predators who don’t like a mouthful of fuzz! And blazing orange Butterfly Milkweed  (Asclepias tuberosa) is thrusting its way up through the tall grass and daisies as well – a food source for the Monarch caterpillar. [Click on photos to enlarge; hover cursor for captions.]

In deep grass at the edge of the trail, a buttery yellow flutter caught my eye. It was a diurnal (daytime) moth with feathery antennae. Knowledgeable folks on the “Butterflying Michigan” Facebook page helped me identify it as a member of the genus Xanthotype. It’s evidently either a Crocus Geometer or a False Crocus Geometer,  but I was also informed that a definitive species identification between the two would require examining their genitalia! Uh, no.

A small Geometer moth from the genus Xanthotype on the path at Charles Ilsley Park

Native bees foraged on flowers in the central prairie too. I’ve learned that it’s nigh on to impossible to identify the species of a native bee from a photograph so I won’t try. But I do love to see these solitary bees at home in our parks, especially a flashy metallic green one like this bee on the non-native Ox-eye Daisy (Leucanthemum vulgare).

Following the path around the Center Prairie in early June, I found one of the small ponds swirling with busy Whirligig Beetles (family Gyrinidae).

A slightly fuzzy photo of a swimming Whirligig beetle as it paused for a second.

These gregarious beetles are beautifully adapted for survival. They row around in circles on the surface with their middle and back legs, probably looking for mates or prey, but also making it tough for would-be predators to catch one! They can also swim underwater if necessary because they trap an air bubble under their stiff wing covers (or “elytra”). They constantly produce a waxy substance that keeps them buoyant and makes them slippery to predators. In fact, males have sticky front legs so the female doesn’t slip from their grasp while mating! Add to that, their split eyes that can see both above and below the water and their ability to fly and it’s clear that whirligig beetles have evolved for survival in pretty sophisticated ways. Here’s a little of the stir they were  creating at Ilsley.

Neonatal Care in the Central Prairie

The nest boxes in the Central Prairie are busy places in June. Birds industriously construct nests inside, lay their eggs, feed their nestling at a relentless pace and eventually frenetically feed the begging fledglings when they emerge. This year the boxes that I’m monitoring sheltered Eastern Bluebirds, Tree Swallows and a House Wren. Luckily, all the birds that I monitor this year lived harmoniously, though the Tree Swallows gave me friendly reminders of their presence by swooping right over my head while I checked their boxes. Here’s a Tree Swallow adult (Tachycineta bicolor) giving me the once over as I passed near its box.

A Tree Swallow on last summer’s  Evening Primrose preparing to dive bomb me –  in a friendly way, of course –  as I approached to monitor a nest.

Tree Swallow eggs are small, pure white and sit daintily in their grassy nests lined with white feathers. After the  writhing, pink hatchlings emerge, it takes about a week for them to begin to develop dark feathers beneath their pink skin, as you can see below. I assume that the white edges on their beaks help adults aim their beaks accurately as they feed each of them in the dark of a nest box or tree cavity.

Tree Swallows love to line their nests with white feathers. These nestlings at about a week old are just beginning to form feathers under skin.

Here’s a lovely lady Eastern Bluebird (Sialia sialis) taking a break from incubation on a nest box in the central prairie.

A female Eastern Bluebird with some food for her nestlings.

Bluebird eggs are usually pale blue and the nest is constructed of grass and sometimes pine needles. Here are some nestlings in a pile in one of my bluebird boxes almost ready to become fledglings. It’s pretty crowded in there with six of them! These little ones napping in a heap are about 6 days from entering the big, bright world outside.

Bluebird nestlings piled this way and that about 6 days before leaving the nest.

A Song Sparrow (Melospiza melodia) paused on a twig with food for its young. Song Sparrows can nest on the ground or as high as 15 feet up in a shrub. I wondered if this one was waiting for me to move along before darting to its nest hidden somewhere in the vicinity. Wish I could see those nestlings!

A Battle for a Nest Box in the Western Prairie

A male bluebird calmly watching a fellow male caught up in a fracas in the western prairie.

Things were not so peaceful in the western prairie. During a birding walk in June, we witnessed a daring feat of courage. For some reason, four adult Tree Swallows attempted to drive a male Eastern Bluebird (and probably the female inside) out of a nest box. We watched the aerial acrobatics of the iridescent blue swallows as they repeatedly dove at the harried male Bluebird who defended the box. The persistent swallows even clipped him with their wings occasionally as he ducked and snapped at them. Here are a series of stills as the battle  raged.

The bluebird stayed right where he was and Tom from our birding group reported finding bluebird eggs inside the next day. Though Bluebirds will not tolerate another bluebird close by, they generally ignore the swallows and vice versa. But not this time.  Hooray for the brave little bluebird!

A Side Trip to the Eastern Prairie in Search of A Tiny Bird

Birders social distancing on their way to the eastern prairie

By traveling around the west prairie and back through the north one, we reach the central prairie trail again which takes us to eastern prairie. I love this rolling landscape full of dancing native grasses and wildflowers. But I only got there once in early June before the windstorm struck. What prompted me was the alert from Ruth Glass who, along with seeing the Yellow-throated Vireo, had also seen the nest of a Blue-gray Gnatcatcher (Polioptila caerulea) in a Box Elder there. When I reached the right tree,  I stood for several minutes scrutinizing it without seeing the tiny nest. But suddenly a Gnatcatcher flew in with food in its beak – and I could see it! My photos were just so-so, but again my photographer buddies, the Bonins, came through. Joan got a beautiful photo of the nest with an adult Gnatcatcher sitting inside so I can share this little beauty with you. Again, the nest is decorated with lichens which not only are beautiful but scientists believe have anti-microbial properties that fend off infections, like mosses do.

Near the wetland on the south side of the prairie, a Common Yellowthroat burbled his “witchedy witchedy” song, declaring his territory to ward off other males. According to Cornell Lab of Ornithology, “Each male normally has only one mate in his territory during a breeding season. However, a female’s mating calls often attract other males, and she may mate with them behind her mate’s back.”  I believe the female’s “ready to mate” call, a fast series of chips, is the second “call” (as opposed to “song”) listed at this Cornell link.  What scamps, those females! But these little birds are contending with predation from carnivorous birds like Merlins and Shrikes and sometimes have to cope with Brown-headed Cowbirds dropping eggs in their nests. Increasing the genetic diversity of their offspring may help the species adjust to the perils of their habitat, or help that female ensure some of her young survive.

Male Common Yellowthroats are calling all over Ilsley now, defending their territory and access to their mates.

On the Way Back:  An Uncrowned King and a Vigorous Bath 

Along the trail back to the parking lot, an elegant Eastern Kingbird (Tyrannus tyrannus) with a white tip on its tail, broad shoulders and a rounded crown perched near the tree line. The Kingbird’s crown, I’ve learned, hides a bright red/orange patch at its center which can be raised in a threat gesture just before dive-bombing any intruder in its territory, even Crows, Red-tailed Hawks or Great Blue Herons flying overhead! Its feistiness and that crown evidently earned it the name Kingbird. I’ve never seen that scarlet crown; I even searched for a photo of it on iNaturalist.org to no avail. But if you want to see a Kingbird’s crown when it’s really riled up, page down a short way at  this link from McGill Bird Observatory! The Kingbird that I saw at Ilsley was considerably more mellow.

Eastern Kingbirds flock together and forage for fruit each winter in the forests of South America.

As I crested a slope on the way back to the car,  I paused at a distance to watch a Northern Flicker (Colaptes auratus) take a dust bath. In a soft patch of dry earth, the bird performed a series of fast gyrations while beating its wings at high speed. When I developed the series of photos, I realized that in its frenzy, this male had exposed his belly by rolling onto his back! I’m guessing he had been plagued by mites and was determined to get rid of them! Here’s the sequence of moves that he made:

Nature Knitting My Raveled Sleeve Once More…

A Carolina Wren that appeared at our home in March. It’s carrying a bit of moss for the nest.

Shakespeare said that it was sleep that “knits the raveled sleeve of care” – and Will was right, of course. But nature is a gifted knitter of cares for me as well. The leafy landscape at home that has soothed me for more than a quarter century is drastically changed –    large sections of it simply absent, twisted, broken, split, dying.

But despite nature’s power to destroy,  it still acts as a balm through it all. When a pair of Carolina Wrens (Thryothorus ludovicianus) disappeared from our yard after the windstorm, I could visit the nest boxes at Charles Ilsley Park to to see pink hatchlings just out of their shells and know life would go on. In Ilsley’s western prairie, the bluebird stood his ground and started his family. The whirligigs danced and dove; blooms rose from the earth and turned their many colored faces to the sun. While sitting at my back door disconsolate, staring at a huge pile of broken tree limbs, two Baltimore Orioles alighted and quickly mated as if to say, “We lost our nestlings in the storm, but here we are, starting again.” And at home, the Carolina Wrens returned four days after the destruction, the male singing his three phrase song as loudly and ebulliently as ever. So through all the craziness of this plague year, I was blessed with short interludes to breathe in the beauty and resilient energy of life despite the chaos around us. And for that I’m very grateful.

A Short Excursion into the Rich Diversity of Blue Heron Environmental Area

Blue Heron Environmental Area on Rochester Road is a place I’ve rarely visited. This special natural area was  purchased years ago by our Parks and Recreation Commission to protect a Great Blue Heron rookery that has since moved on.  The township has begun planning for the area’s future use, but for now it’s preserved as a beautiful green space with a large arc of wetland curving through a high-quality lowland forest. The fields outside the forest are planted by a local farmer which helps prevent the spread of invasive shrubs until future plans come to fruition.

Until recently, I had only been in this forest to pull garlic mustard during spring volunteer workdays. But in early June, I was able to join our township Stewardship Manager Dr. Ben VanderWeide and his stewardship specialist, Grant VanderLaan, for a short exploration while they there were clearing invasive plants. What a great opportunity to share some of the special flowers, vivid dragonflies, and elder trees that inhabit this moist, shady world!

Escorted Along the Fields by a Fleet of Dragonflies!

While skirting the farm field near Rochester Road, I noticed a sunlit meadow to my right that was splashed with blossoms of native Daisy Fleabane (Erigeron annuus).

The sturdy, daisy-like faces of native Daisy Fleabane dotted a restored field at Blue Heron.

All along the field edges, dragonflies were patrolling, and occasionally dueling over, their territories. Blue Heron Environmental Area is ideal for these aerial wizards. In the open areas, they can scoop up mosquitoes, flies, midges or even moths and damselflies out of the air, while attracting a mate with their speed and skill. And once they do mate, the forest wetlands provide an ideal spot for depositing their eggs. Since walking humans stir up a lot of insects, they were also happy to accompany me along the field edge to harvest whatever I stirred out of the grass.

The Widow Skimmer female below (Libellula luctuosa) looks very like the male, except that her abdomen is black and gold while his is gray-blue. The male also has white patches beyond the dark brown ones on each wing. Widow Skimmers find shelter at night by hanging underneath overhanging leaves.

Widow skimmer female or juvenile 2 BHEA
The offspring of this  female Widow Skimmer (Libellula luctuosa) will resemble her closely, but with male juveniles,  the gold stripe on its abdomen will gradually fade to gray-blue.

Eastern Pondhawks (Erythemis simplicicollis) are fierce predators. They have long spines on their legs for grasping prey, which includes any insect their size or smaller – occasionally even other Eastern Pondhawks! These dragonflies are more likely than others to follow along as you walk in order to feast on swarms of insects. Eastern Pondhawks are “dimorphic,” meaning the male and female look very different as you can see below.

During maturation, this male Eastern Pondhawk’s abdomen slowly turned to blue-gray starting at the tip of his abdomen and ending at his thorax. This guy looks ready to take me on!

According to Dragonflies of the North Woods by Kurt Mead, female Eastern Pondhawks can mate multiple times in a day. Perhaps the female’s bright green color and striped abdomen, so different from the male’s, makes her more visible to possible suitors.

A female Eastern Pondhawk can lay up 2100 eggs per day. She releases them into the water by dipping her abdomen into the water in short intervals.

The Twelve-spotted Skimmer (Libellula pulchella) is a favorite of mine not only because of the alternating stripes on its wings, but because of the way it hunts. It sallies forth from a perch to snag its prey, and then frequently returns to the same perch repeatedly – giving amateurs like me multiple chances for a decent photo! All dragonflies are a challenge to photograph in flight, but particularly Twelve-spotteds since they fly in bursts of speed and can reverse direction in a flash.

The male Twelve-spotted Skimmer sometimes hovers over the female during egg-laying to prevent other males from harassing or mating with her.

The Common Whitetail (Plathemis lydia) below could be a female, but is more likely a juvenile, since they’re the ones that tend to head for fields and open areas, leaving the water behind once they emerge from their larval stage. Their appearance is not only identical to the adult female; it also closely resembles the female Twelve-spotted Skimmer. The only difference is that the yellowish-white stripes of the female/juvenile Whitetail form a jagged line down the sides of the abdomen (see below), while the side stripes of the female Twelve-spotted form a neat straight line. So needless to say, I always need a photo to decide which one I saw when a female of either species appears.

A juvenile Common Whitetail is more likely to be found at a field edge than the adult female, though both look exactly alike during early maturation.

I came across two other interesting insects at the edge of the fields. Noticing delicate movement at my feet, I finally spotted a strange creature that is completely harmless to us humans, but quite a predator! A Hangingfly (genus Bittacus) does just as its name implies; it dangles beneath leaves by its looong front legs which have claspers to grasp leaves or stems for support. It uses its other four legs to snag any unwary insect passersby. It looks a bit like a Crane Fly but isn’t related.

A Hangingfly hopes to snag unsuspecting insects as it dangles from under a leaf.

And a Six-spotted Tiger Beetle (Cicindela sexguttata) showed up right where they always are – in a bright spot at the edge of a field or forest, its stiff, iridescent green wings shining in the sunlight.

A Six-spotted Tiger Beetle paused in a sunlit spot on an old log at the edge of a field.

Something New:  Restoring a Forest

A field now cleared of invasive shrubs that will eventually be restored to the forest it once was.

Have a look at the photo of the cleared, green field above.  Until two years ago, it was choked with Autumn Olive and Glossy Buckthorn, invasive non-native shrubs that quickly take over abandoned farm fields. A forestry mower took them down in the winter and the area was soon sown with native grasses and wildflowers. The stewardship summer crew treated the invasive shrub regrowth the following summer.

Often stewardship work in our township begins with this clearing process as the first step in turning a field back into a native prairie or savanna- but not so at Blue Heron.  When I visited, Ben showed me that the cleared field in the photo had originally been part of an earlier forest.

As you enter the woods, you can see a demarcation where younger, smaller trees give way to taller, thicker, older ones.  It’s likely that decades ago, the older trees,  many of which lean eastward,  had been reaching for sun at the edge of a farmed field . The bigger trees to the right in the photo probably grew back after the forest was originally cleared for farming in the 19th century. The smaller trees to the left probably sprouted after part of the field was no longer farmed in the second half of the twentieth century.

Older, larger trees on. the right were once leaning into the sun at the edge of the field when it was farmed years ago. Smaller trees beyond started growing when part of the farm field was abandoned many years later.

Stewardship plans include eventually planting native oaks in the open, cleared meadow  in order to restore more of the native trees that thrived here before farming began. I’d love to be around to see the restoration of a forest!

The Rich Diversity of a Lowland Forest

Blue Heron Environmental Area is a high-quality lowland forest with a curving arc of wetlands.

I’ve only explored a small section of the current woods at Blue Heron Environmental Area, but I’m already wowed. In the sources I used to research the plants I saw here, I  came across phrases like, “found only in high-quality wetlands,” or “found in high quality woodlands.” Because much of the forest has been undisturbed for a long time, Blue Heron provides high-quality examples of both.

Moist Forest Flora – and Some Rare Beauties!

As I stepped with Ben into the older forest, the shade deepened. Ben kindly took me to see a unique orchid. It seems that at one time, this natural area hosted two kinds of Ladyslippers. The more common, and still lovely Small-flowered Yellow Ladyslipper (Cypripedium parviflorum var. makasin) peeks out of the greenery beneath the tall trees. I love how the dark sepals form the purplish ribbons of the lady’s slipper.

The sepals of the Small-flowered Yellow Ladyslipper that once enclosed its bud look like the ribbons that wound around a lady’s leg to secure her shoe in ages past.

But there was once another orchid here which Ben and Grant haven’t yet spotted, the  rarer White Ladyslipper (Cypripedium candidum)Here’s a photo of one from iNaturalist.org taken by photographer Erin Faulkner. Note that the sepal “ribbons” are green with faint flecks of purple rather than the dark purple and bright yellow sepals of the Yellow Ladyslipper above.

Ben thinks the rare White Ladyslipper must have cross-pollinated with the Yellow Ladyslipper to create a hybrid at Blue Heron. Photo by Erin Faulkner (CC BY-NC)

Ben presumes that White Ladyslippers once grew in this natural area because here and there today grows a hybrid between these two native orchids. The hybrid wildflower at Blue Heron has the white “slipper” of the White Ladyslipper but the purple, sepal “ribbons” of the Yellow Ladyslipper. The two native Ladyslippers must have cross-pollinated and produced this special hybrid that Grant found. I’m so glad that I got to see several of them and am able to share one with you!

The hybrid Ladyslipper at Blue Heron has the white “slipper” of the White Ladyslipper and purple sepal “ribbons” of the Yellow Ladyslipper.

Also enjoying the beautiful forest floor, I noticed little yellow pom-poms on a stem growing in the mottled shade of a long, arcing marsh. Ben identified it as Tufted Loosestrife (Lysimachia thrysiflora), a species of Loosestrife I’d never seen before. Its clusters of tiny blossoms, called “racemes,” emerge from the middle axils of the long, graceful leaves like tiny fireworks. It’s described by a useful wildflower website, Illinois Wildflowers, as “found in higher quality wetlands.”

The yellow racemes (clusters of separate flowers) of Tufted Loosestrife catch the light and shine in the shade at the marsh’s edge.

Large areas near the marsh were carpeted with a calf-high plant I’d never before noticed on my hikes –  Richweed (Collinsonia canadensis). This member of the mint family produces a plume or spike of tiny yellow flowers in mid-summer, adding a spark of color to the dense shade when little else is in flower. Since I saw only its leaves, here’s a photo of the plant blooming by inaturalist photographer Sirruba.

Ferns Waving from the Forest Floor

The feathery fronds of a glorious variety of ferns sway above the ground near the marsh at Blue Heron Environmental Area. Ben  identified two for me and I spotted an old favorite as well. The Maidenhair Fern (Adiantum pedatum) is described by Illinois Wildflowers as “found in higher quality woodlands where the original ground flora is largely intact.” I saw its fan-shaped fronds spiraling out of the ground quite near the center of the marsh’s arc. It carries its spores in narrow bands on the underside of the leaflets near the tip. Each leaflet on the frond folds down slightly to partially cover the sporangia, the structures that carry the spores. They will eventually break open and release the spores to the wind.

Maidenhair Fern enjoys the humid shade of Blue Heron.

The Royal Fern (Osmunda regalis) produces a glorious, rising plume of infertile fronds that catch the sunlight and feed the plant through photosynthesis. The shorter, straight fertile fronds are thinner and produce yellow bead-like spores. The draining of wetlands around the world has had a big impact on Royal Ferns, so I’m happy to have seen so many here!

A Royal Fern near the marsh rises like a large, green bouquet rising from the moist forest floor.

All over the woodland grows an old friend, the Sensitive Fern, reportedly so-named because its fertile fronds wither at the first frost and arrive after the last frost. Its green, infertile fronds with their jagged edges feed the roots while the smaller fertile fronds eventually produce shiny, brown, bead-like sporangia that last through the winter before breaking open to release the spores. Sensitive ferns also reproduce by underground stems called rhizomes.

Wet Woods Extras

High Bush Blueberry (Vaccinium corymbosum), an unusual native plant that I’ve only seen before at Cranberry Lake Park, huddled under the shade of a willow on a hummock in  the marsh. When I got closer with my camera, I could see fruit just beginning to form. Native mining bees and bumblebees or non-native honeybees must have found the little white nodding blossoms and pollinated them as they foraged. Some lucky bird or mammal has a treat coming!

The petals of Highbush Blueberry blossoms have dropped and the fruit is forming.

Near the Blueberry bush, in a wet crevice of a moss-covered hummock, I spotted a tiny Wood Frog (Lithobates sylvaticus).  It must have hatched this spring from eggs quickly laid in a vernal pool back in March. Less than 2 inches long, it floated in the shallow water or rested on the moist mud as it explored its shady grotto.

Healthy Little Saplings, a Majestic Beech and Some Colorful “Hangers On”

Among the mixture of maples and oaks, some trees that I see less often have also found a suitable habitat in the forest at Blue Heron. Ben told me of a large Tulip Tree (Liriodendron tulipifera) farther back in the woods that I’d missed. But I did see this little sapling of one springing up from the moist earth. I love how tiny saplings create such large leaves to capture as much sunlight as possible. Let’s hope it escapes the attention of foraging deer!

A tiny Tulip Tree will have to survive foraging deer to reach its adult size.

I did find an impressive American Beech (Fagus grandifolia) reaching up to the sunlight with its smooth, gray bark. Wildlife love the plentiful beechnuts that this tree will send rattling to the earth. And according to the Trees of Michigan Field Guide by Stan Tekiela, the seedlings and saplings that manage to take root can survive in the shade for years waiting for other trees to fall, giving them the sunlight and space they need. I’m hoping for a grove of Beeches – a new favorite of mine.

A huge American Beech made its way up into the sunlight in the forest at Blue Heron.

A tiny Swamp Oak (Quercus bicolor) must have begun its upward journey from the forest floor when the acorns dropped last fall. Swamp Oak acorns usually come in pairs and sprout shortly after falling, according to Stan Tekiela. If one survives hungry birds and animals, it grows more quickly than most oaks. And it could live for up to 300 years,  according to Wikipedia. Good luck, little oak!

Leaves of Swamp Oaks are dark green above and lighter below – hence its species name, “bicolor.”

What first appeared to be some sort of fungus had sprung up around a large fallen oak in the woods.  But it wasn’t a fungus; it was a parasitic plant commonly called Cancer Root or Bear Corn (Conopholis americana). It’s an underground plant that consequently can’t photosynthesize sunlight. Instead it feeds off the roots of woody plants, especially oaks and beeches. This interesting pinecone shape is the flowering stem of the underground plant which grows on the roots about four years before producing these flowers that can grow as high as 8 inches. I’m continually amazed by the variety of ways that nature has found to sustain life.

Cancer root or Bear corn draws its sustenance from the roots of trees since the plant is underground and can’t photosynthesize. These are its flowers.

Imagining Blue Heron’s Past, Protecting It Today and Restoring It For the Future

A section of the long crescent of marsh at Blue Heron Environmental Area.

The distant past of this striking lowland forest can only be imagined. Before farming began here in the 1800’s, an old growth forest probably stretched out from its present site across where Rochester Road is now and beyond. Gray wolves probably roamed the area, keeping a healthy deer population in check. Those White Ladyslippers may have bloomed in profusion in an open wet meadow pocket, since non-native plants had not yet been introduced to the ecosystem.

Today Blue Heron is a special natural area preserved by the Parks and Recreation Commission and the residents who support our parks. The old growth forest is gone, but large trees from the 19th century still stand tall among the wetlands shading a forest floor full of native plants. Thanks to our stewardship program, garlic mustard and other invasive trees, flowers and shrubs – some brought early on by European settlers, others unwittingly planted in our gardens or along our streets – are being removed from our parks and controlled in a variety of ways,  including prescribed burns. As a result, our heritage of native plants can begin to reassert itself, providing a healthier, more productive habitat for native wildlife.

And for those of us who want to pass that heritage on to future generations, we can dream of young children wandering among tall oaks and waving native grasses that were restored to Blue Heron Environmental Area by people in our time who valued the gifts of the natural world. What a legacy, eh?

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!

An excited male Ruby-crowned Kinglet with his crest raised – a rare sight to see with this busy little bird. Photo by Bob Bonin with permission.

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.

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.

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 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.

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.
