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.

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.

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

A maturing toxic Amanita mushroom

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

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

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

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

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

A Chanterelle mushroom with its fake gills on the stalk.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Cranberry Lake: Summer Ushers in Birds, Butterflies and Blossoms

Wild Geraniums along the Hickory Lane

 

Blog and Photos by Cam Mannino

Summer finally made its appearance all over the woods, meadows, wetlands, and forest edges of Cranberry Lake Park.  After a prescribed burn this spring, geraniums and trillium emerged under the huge Shagbark Hickories that line the park’s western edge. Summer birds, including the tiny warblers and other new arrivals, are singing lustily to establish their territories and attract interested females as they begin to build nests. Butterflies are just starting to dance above the greenery in the dry meadows. And the hibernators – like snappers, raccoons and  leopard frogs – get back in action after their winter snooze. The transformation from spring to summer has well and truly begun.

Birds and Blooms in the Large Sunny Meadows

Small Yellow Warblers (Setophaga petechia) welcome visitors from the high treetops just north of the parking lot. The male with his chestnut-striped breast sings his “sweet-sweet, I’m a little sweet” song as he darts here and there, frequently out of sight in the greenery. Luckily a female with much fainter stripes ignored me while probing for insects in some smaller trees.

A female Yellow Warbler probed the branches of a small tree near the western entrance to the park.

At the edge of the big northern meadow one afternoon, I heard the two buzz call that Ben identified on an earlier birdwalk. As I scanned the bushes with my binoculars, a lovely Blue-Winged Warbler (Vermivora cyanoptera) filled my view. By the time I raised the camera, it was gone. Joan Bonin, a gifted local photographer and birder, kindly offered her stunning photo taken a week later at Port Huron State Recreation Area.  Thank you, Joan!

This gorgeous photo of a Blue-Winged Warbler was taken by local birder and photographer extraordinaire, Joan Bonin.

Red-eyed Vireo (Vireo olivaceus) made a brief appearance in a small meadow opening at the edge of a forested wetland. Evidently these little birds sing incessantly, especially on warm summer afternoons. In fact, Cornell reports that one determined male “sang 22,197 songs in the 14 hours from just before dawn to evening, singing for 10 of those hours.” I missed both his song and a photo, but another gifted local photographer and birder, Bob Bonin (Joan’s husband), kindly shared his lovely photo taken at the Tawas migration site last year. Thanks to Bob, also!

Steve, a fine birder that I met at Bear Creek Park, commented on the last blog that he’d seen an Indigo Bunting (Passerina cyanea) at Cranberry Lake in the last two weeks.   Cornell ornithologists report that all blue birds actually have no blue pigment in their feathers. “Their jewel-like color comes instead from microscopic structures in the feathers that refract and reflect blue light, much like the airborne particles that cause the sky to look blue.” Since Steve saw the bird and I didn’t, here’s that  bright little piece of sky in another beautiful shot by Bob Bonin.

Indigo Buntings sing as many as 200 of their two or three phrase songs per hour at dawn according to Cornell Lab.

Butterflies dance across nearly every sunny or dappled area of Cranberry Lake. In a shady corner near the northern meadow, an Eastern Tiger Swallowtail (Papilio glaucus) paused for just a moment before sailing high into the treetops and away. The band of blue spots at the bottom of the hindwing (plus the orange center spots) marks this one as a female.

A smaller, but equally striking butterfly, the American Copper, sampled the blossoms of Common Blackberry bushes (Rubus allagheniensis) that have multiplied mightily since the recent burn.

According to Wikipedia, the male Coppers set up “small territories which they will defend vigorously against rival males or indeed any unlucky passing insect. Even the shadow of a large bird passing overhead is enough to elicit a response.”

It’s clear where this medium-sized [edit:  My memory failed me.  It’s actually very small!] butterfly  got its name, eh?

This female Eastern Tailed-Blue butterfly (Cupido comyntas) doesn’t wear the beautiful blue that her mate flashes when he flies. But you can still see a bit of blue in her modest gray. These medium-sized butterflies almost disappear when they land and fold their wings, which are light gray underneath.

A female Eastern Tailed-blue butterfly is a more muted gray-blue than her brighter blue mate.

Along the Hickory Lane, More Bird Song and Early Summer Blossoms

On an early bird walk, a Brown Thrasher (Toxostoma rufum) belted out its complex mimicry song from the top of a tree on the Hickory Lane. If you enjoy the Gray Catbird’s mix of other birds’ calls and the odd noise,  you’ll love (as I do) the crazy mix of continuous loud song from the thrasher. That morning he was too high up for a good photo. Fortunately  a few days later, a tired thrasher, preparing for sleep on a cool spring evening at Gallagher Park, struck a pose for me.

This Brown Thrasher was preparing to sleep on a cool evening – one leg tucked up under his feathers which were fluffed for warmth

Along the lane,  a tiny mimic (listen to the second recording at this link), the Blue-Gray Gnatcatcher (Polioptila caerulea), busily fluttered and hopped about a tree trunk foraging for insects. How I’d love to see their nest!  Cornell Lab says they “use spiderweb and lichens to build small, neat nests, which sit on top of branches and look like tree knots.”

The Blue-gray Gnatcatcher cocks his tail with its white outer feathers this way and that as he searches for insects – but not many gnats, despite its name!

On a later visit, a male House Wren (Troglodytes aedon), bubbled with spring song. Despite their diminutive size, wrens can be fierce in asserting ownership over a preferred nesting hole, even dragging out eggs of other birds or pecking larger adult birds. Wrens need to maintain a narrow range of temperature for their eggs to hatch which might explain their fierceness over nesting sites. Perhaps this male’s insistent song was just a first salvo in the competition.

The effervescent singing of a House Wren on the Hickory Lane.

In the area between the Hickory Lane and the large marsh to the east, a strange upward sliding call made my husband and I stop and listen one afternoon. We never saw the singing male, but we did spot the female Swainson’s Thrush (Catharus ustulatus), that I originally thought was a robin from its stance.  Sorry for the slight blur of a quick photo.

A female Swainson’s thrush stopped with us to listen to the hidden male singing his ascending whistle of a song.

Below these avian songsters, early summer blossoms came burgeoning forth after a recent prescribed burn. The lane was filled on both sides with the Wild Geraniums (Geranium maculatum) you see at the top of this blog. A small white plume poked through leaves of what Ben tells me is either red or white Baneberry (g. Actaea). The actual baneberries that form later are highly toxic, so please don’t eat them! (They’re very bitter so you wouldn’t like them, but children might be tempted because they’re very colorful and shiny.)

Two varieties of the same flower also bloomed on the lane.  Solomon’s Seal (Polygonatum biforum) produces its blossoms beneath the stem and its leaves are smooth below, unlike a nearly identical plant, Downy Solomon’s Seal (Polygonatum pubescens) that has fuzz on the underside of the leaves.

Solomon’s Seal hangs its blossoms below the stem, as does Downy Solomon’s Seal but the undersides of leaves on Solomon’s Seal are not covered in downy fuzz.

False Solomon’s Seal (Maianthemum racemosum), on the other hand, produces its flowers on a stem that stands above the leaves. Odd name. Perhaps the name was given by someone fooled into thinking at first that it was Solomon’s Seal? Who knows….

False Solomon’s Seal carries its blossoms on a stem above the leaves.

Early Summer in the Shadowy Wetlands near Cranberry Lake

Cranberry Lake has a wonderful collection of vernal pools and woodland ponds as well as the lake itself. I’ve come to love these areas because they are always rich with wildlife, especially birds!

I heard the easily-identified “witchedy, witchedy” call of one of my favorite small migrators, the black-masked Common Yellowthroat (Geothlypis trichas). He was in a favorite location, in low bushes near a wetland. I never got to see the ones that I heard repeatedly at Cranberry Lake, but I saw this one the following week at Charles Ilsley Park.

The Common Yellowthroat sings his “witchedy-witchedy” song from low bushes, usually located near a wetland.

In a forested pool, a Common Snapping Turtle (Chelydra serpentina) had draped its head over the edge of a log, evidently eating plants below. At first, I thought it had been beheaded somehow! But on hearing me crunching in the twigs, it lifted its pointed snout into the air, quickly slid backwards into the water and disappeared. So all I got was this odd, headless shot.

A snapper in a forest pond with its head submerged eating plant material, no doubt.

A few minutes later, a male Common Grackle’s (Quiscalus quiscula) iridescent head shone in a ray of sunlight on the same log. Clearly frustrated at finding nothing to eat beneath it, he tossed that irritating, useless chunk of bark into the water.

A male Common Grackle tossed his chunk of bark into the water after checking and finding no edible insects underneath. At least that’s how it appeared.

One of summer’s pleasures is being escorted along a trail by dragonflies and damselflies – and then I managed to shoot one swooping over the water when I reached at Cranberry Lake.  Perhaps a mating flight?

In April, lovely little blossoms with pink scallops and ruffled edges emerged on the native Highbush Blueberry (Vaccinium corymbosum) near Cranberry Lake. A few weeks later, the fruit was beginning to form. I hope birds, animals and we humans leave some berries uneaten so it keeps spreading!

When I reached Cranberry Lake, I found two Sandhill Cranes (Antigone canadensis) standing on a sandbar near the shore. One of them “gave me the eye” between the old stems of purple loosestrife.

On the way back up the trail from the lake one morning, Ben spotted a weary raccoon who appeared to have made a hasty bed in the fork of a tree after a night of foraging. It opened one eye as we birders peered from below.

A weary raccoon opens one eye to look back at us from what appears to be a hastily constructed napping place.

On the edge of the path heading toward one of the large meadows, I heard the snoring rattle of the Leopard Frog’s song coming from a nearby wetland. And then, oops! – one appeared right in the path between two wet areas. Nice to have frog song along with bird song on a summer walk!

The Leopard Frog’s appearance nicely matches its name. Its song is a low, snoring sort of rattle – very distinctive.

Nature by Ear as Well as by Eye

The forest pond where the Grackle and the Snapping Turtle spent a quiet afternoon.

To truly savor the pleasures of nature in early summer requires tuning my ears as well as opening my eyes. Though I’m just learning bird songs and frog songs, every time I identify a voice in nature’s chorus, I feel more connected, more embedded in the natural world. Listening, as well as careful, patient watching, begins to turn a green landscape into an intricately woven tapestry of life in which we humans are just one colorful thread.
