Charles Isley Park: Dressed in the Gold and Black of Late Summer

Do me a favor, would you? Imagine standing in front of a huge meadow full of tall grass and wildflowers dancing in a soft breeze. You can hear crickets and cicadas singing in the deep grass. Now turn your computer’s volume to about half and click on the arrow in the image below. (You’ll hear a little of the wind in the microphone.)

There! That’s a bit of what it’s been like at Charles Ilsley Park in the last few glorious weeks of August.  Goldfinches sing as they swoop in their roller coaster flights across the fields that are burnished with goldenrod. Butterflies, with golden wings fluttering, sip sweet nectar from the giant thistles. And all of this gilded beauty is backed by the sounds of a summer breeze sighing in your ear and the buzz of cicadas and crickets. That’s about as close to pure glory as my life affords.

The Glow Began in July…

The eastern path through the central meadow at Charles Ilsley Park on July 15, 2019

Let’s just say the Black-eyed Susans (Rudbeckia hirta) got magnificently carried away in the central meadow at Ilsley. Perhaps the contractor who planted wild seed last year had a wee bit too much of them in the mix? But I didn’t hear anyone complain when the meadow was literally blanketed in black and gold. By early August, they had browned, leaving behind seeds that will provide nourishment for migrators and winter birds.

Nature Comes Back with a Second Wave of Gold

A female Monarch (Danaus plexippus) stares out at me from a Black-eyed Susan finished off from the intense heat of July. Her wings are a lovely soft gold underneath.

In their place, though not quite as abundant, came a close relative, the buttery yellow Brown-eyed Susans (Rudbeckia triloba). Instead of a single flower on each stem like their black-eyed cousins, these Susans produce branching stems with profuse, but smaller blossoms which create a similar sunny effect.

Brown-eyed Susans emerged just as the Black-eyed Susans faded, though not in quite the same profusion.

Of course, August always brings waves of different Goldenrods to keep the gold coming in late summer. Right now, I commonly see three different ones: the cascades of Canada Goldenrod (Solidago canadensis), Stiff Goldenrod  (Solidago rigida) with its ramrod stems lined with clinging oval leaves and bouquet-like sprays of Grass-leaved Goldenrod (Euthamia graminifolia) which is from a different genus of the Aster family. Later in the month, we’ll begin to see the  upright, lemon yellow plumes of Showy Goldenrod (Solidago speciosa) doing its part to keep the fields golden right into September. (Click on photos to enlarge; hover cursor for captions.)

The Gray-headed/Yellow Coneflowers (Ratibida pinnata) add their droopy charm to the fields too, though their best days are behind them for this season. And the tall spikes of Common Evening Primrose (Oenothera biennis) are topped by gold blossoms that stay open from evening until early morning, and later on cloudy days as well.

I love how native plants host so many insects in an era when the insect world is suffering from plunging numbers all over the planet. Here two False Sunflowers (Heliopsis helianthoides) standing next to each other hosted a Soldier Beetle (Cantharidae family) and the nymph of a Katydid (Tettigoniida family). Have a closer look at the amazing length of the katydid’s antennae by clicking on the right photo. One of the ways you can tell a grasshopper from a katydid is that grasshoppers have much shorter antennae than the very long, fine ones you’ll see on the nymph below.

Out in the far west of the park at the edge of the woods, a tall, striking, yellow flower with very unusual blossoms caught my eye. Dr. Ben VanderWeide, our township Stewardship Manager, identified it for me as Wingstem (Verbesina alternifolia)and indeed, its flat stem had narrow “wings” on either side. Wingstem flower heads cluster at the top of the 3′-8′ stem. Each bloom is actually a flower within a ring of flowers. The “disc florets” in this plant are the tube-shaped flowers that thrust outward from the center of the flower head. What looks like a ring of petals around the central disc is actually a ring of “ray florets” and each of them is an individual flower that has the ability to produce its own seed. In botany, “florets” are individual flowers within a flower head, whereas what we see as individual petals on ray flowers are really three petals fused together. And how about those curly little stigmas that we see whimsically protruding from the ends of the disc florets! What a fun wildflower!

Wingstem is not seen a lot in Michigan, but it’s now growing in two of our parks!

Wingstem has a limited distribution in Michigan, so we’re lucky to have them. These Charles Ilsley Park plants grew from seeds that Ben collected at the township’s Blue Heron Environmental Area, which was the only place he’s seen them in the township. It’s exciting to know that the seeds Ben planted at Ilsley have taken hold, so that we now have two parks in which this unusual native plant has found a home.

Birds Matching the Black and Gold Landscape

Let’s Start with A Goldfinch Saga!

American Goldfinches (Spinus tristis) – Unlike most other birds, Goldfinches start mating around mid- to late-July when the thistles bloom, which is a source for both nesting material and food for them. Once the first broods fledge in early August, most Goldfinches mate a second time.

On August 9, Mike and Joan Kent, birding friends, took a walk at Ilsley and spotted a nest in a thistle.  Joan peeked in and saw 3 eggs. They noticed a lot of Goldfinches nearby and assumed it was probably the nest of one of them. And that was that, until…

On our Wednesday bird walk on August 21, Vinnie Morganti, another member of our bird group, spotted the same nest located within the thorny stems of a tall Bull Thistle (Cirsium vulgare). A Goldfinch’s cup nest  is woven from plants and root fibers and lashed to a bush or plant with spider silk. Then it’s lined with thistle down which makes it close to waterproof inside. A small masterpiece. This pair chose a location which probably deterred predators, though it may have been a bit hard on the parents’ wings while feeding!

Peeking into the nest, I discovered  4 baby birds. Fellow birder, Tom Korb, got a photo of the blind and slightly fuzzy hatchlings by valiantly sticking his cellphone into the thistle above them. Tom and I decided to share monitoring these little birds until they fledged and report our findings to Cornell’s Nestwatch , a citizen science site we use for our township nest boxes.

We bird monitors are trained not to go to a nest more often than every 3 – 5 days. So when I returned to the park the following day, I stood far off looking through a long lens. Imagine my delight when I saw one little head popping up above the nest! I don’t know if it could see the meadow yet. Perhaps it was just enjoying the breeze ruffling its Einstein hairdo!

The fuzzy head of a goldfinch hatchling facing out into the meadow, perhaps to catch a breeze.

I came back to monitor on August 24 hoping to get a photo inside the nest despite the thistle’s thorns. I’d brought along the fancy, black leather gloves my mother had given me years ago to wear to  the theater – but here I was using them to reach inside a thistle! I could picture my mom laughing and shaking her head – but the gloves worked beautifully! In the photo, I could see the opened eye of at least one little nestling, though the rest were snoozing in their sturdy nest cup. It appeared that the beige tips of feathers might be emerging from their dark sheaths. We think now that they were about a week old in this photo.  They’d come a long way  from those blind babies in just 3 days!

Three days after we first saw them, their eyes were opening and their yellowish-beige feathers began to emerge from their sheaths. They were about a week old.

At our August 28 bird walk in another park, Mike Kent told us about his wife seeing the nest at Charles Ilsley Park on August 9.  Good news for us monitors, because that allowed us to use the guidelines on the Nestwatch site to estimate the age of the Goldfinch hatchlings more accurately. After the bird walk, I accompanied Tom on his monitoring trip to the Ilsley nest. What a change! Little heads peered up over the nest edge – eyes and beaks open. According to the Donald W. Stokes’ Guide to Bird Behavior (Vol.1), during their first week after hatching, Goldfinch nestlings are quiet but will silently reach up for food if the edge of the nest is tapped. In the second week, these nestlings begin making a lot of noise – but wisely only do so when a parent arrives with food. Tom got a great photo of the bright red mouth of a begging, but silent, youngster!

That day, all the nestlings, now about 11 days old, looked bright and alert, peeking out into the world and fully feathered. The Stokes Guide explained that those white blobs on the nest are fecal sacs, the avian equivalent of soiled diapers. Goldfinch nestlings are quite fastidious. The first week after the young hatch, adults carry the waste sacs away from the nest. But starting in the second week, little goldfinches back up to the edge of the nest and drop these little packages over the side!

A nestling peers at me from the nest at 11 days old, surrounded by the fecal sacs that  it and the others have dropped over the nest edge.

My last turn at monitoring the nest was on August 31 – and the nest was empty. The nestlings had become fledglings. Our estimate is that they fledged on their 12th or 13th day after hatching. The nest was remarkably clean inside (if not outside) which might have meant a healthier, more comfortable environment for the nestlings.  

I could hear a fledgling begging far off in a stand of thistle and through my binoculars, I thought I saw a couple of small birds fluttering among the stems. A female flew in among the thistle, perhaps feeding “our” fledglings from her second brood. A male seemed to be on sentinel duty nearby before he flew off to gather more seed. Off into the world for our Goldfinch fledglings! And the end of our nesting saga.

Hard-working Goldfinch Adults

While the females incubate a second brood, male Goldfinches  are on their own in feeding the first brood – which can be as many as seven fledglings, according to Cornell’s nestwatch.org! Begging calls of first brood youngsters could be heard a week ago as young fledglings pursued their harried parents around the park or called from the treelines to be found. This little Goldfinch fledgling seemed a bit more mellow than the rest.

A goldfinch fledgling watching for its father and no doubt hoping for a meal.

The Goldfinches’ primary food source is thistle seed so I’ve seen males all over the fields with thistle down (pappus) hanging from their beaks. They dig industriously into the seedhead, pull out the down, carefully nibble off the seeds and then let the down fly. Stokes informed me that they feed partially digested seed to their  young, as they also do for the mate during her first week on the nest. Quite a responsibility!

More Gold and Black Birds!

In a bush in the far west meadow, I saw a flash of yellow and took a quick couple of shots as a bird perched for a moment and then flew.  I wasn’t sure what I’d seen. Local birding expert, Ruth Glass, identified it as a female Baltimore Oriole (Icterus galbula.) She told me that by now most of our summer orioles have left for Central or South America with their young, so the one I saw was likely a migrator from further north.

The birding group saw other birds sporting lovely yellow trim. A trio of Cedar Waxwings (Bombycilla cedrorum) perched far above in a bare tree. Through binoculars, two clearly had the yellow bellies and yellow tail bands that identify this handsome bird. Juveniles have a fainter black mask and some brown streaking on the breast, but in this distant photo against a gray sky, it’s hard to tell if any of them were juveniles or adults .

Cedar Waxwings added their bright yellow bellies and yellow-tipped tails to a golden August morning.

Ruth Glass also helped me identify a strange looking dark bird that mystified me. She said she was “95% sure” it was a male Indigo Bunting (Passerina cyanea) molting from his brilliant blue breeding colors  into his mostly brown non-breeding colors which are similar to the female Bunting. This mottled look is common for males during the molt. I would never have guessed! Thank you, Ruth!

Some large dark brown birds also added contrast to all the gold around them. A trio of Turkey Vultures (Cathartes aura) rested on a broken snag near the edge of the center field. Through the trees on my way into the park, I saw one of them spreading its magnificent wings to the sunlight. They do this to warm them, stretch them, or to expose any bacteria on them to air and light.

Around the corner, two other vultures perched on a broken snag. This one made me smile, because it looked as though it was appealing for a little sympathy. I’m afraid vultures don’t get much appreciation, though I think their soaring flight is graceful and the cleanup services they provide are crucial. Really, though, the bird was just preparing to preen.

Another vulture looks like it’s asking for sympathy, but it’s really just starting to preen.

The first vulture suddenly flew straight up in the air and landed rather awkwardly on a branch that was much too short. It fluttered clumsily right, then left, until it finally found its footing. Is it my imagination or are the other two a bit embarrassed by the graceless landing skills of their compatriot? Probably, my imagination….  (Tap arrow to play and to pause for reading captions.)

Butterflies Complement the Color Scheme

This August the huge, dramatic Giant Swallowtail butteflies (Papilio cresphontes) arrived in Charles Ilsley Park in large numbers. One afternoon about two weeks ago, perhaps a dozen of them landed delicately on the large purple blooms of Bull Thistle, or hovered in front of them, extending their long proboscises to sip while avoiding the thorns. I don’t know if this thistle is a favorite plant for these big butterflies or if they were just the biggest blooms with the most nectar when they arrived. They chased each other over the fields, creating a shimmer of gold and black all over the central meadow.

A Giant Swallowtail, one of many at Ilsley in August, sips nectar from a Bull Thistle.

You’ll note that the one above has a few missing pieces on its wings and that the black edges look a bit worn. I compared the very tattered dorsal (upper) side of one I saw on thistle at Charles Ilsley Park in late August with the fine specimen I saw on Bee Balm (Monarda fistulosa) at Stony Creek Ravine Nature Park in late July a couple of years ago. I wondered if the difference in wear and tear was due to feeding among thorny thistles or perhaps just the normal battering big wings take after an extra month of foraging and mating. I’m guessing a bit of both.

These dramatic swallowtails have expanded their range further north since about 2001 when first frosts became more uncommon in September – perhaps an effect of global warming. They lay their eggs on plants that will act as hosts for their larvae, which includes two of our abundant natives, Swamp Milkweed  and the Solidago genus of Goldenrods.

The Eastern Tiger Swallowtail (Papilio glaucus) made its elegant contribution to the black-and-gold meadows. These high-flyers raise 2-3 broods each summer. Their caterpillars spin a remarkable chrysalis that matches dead wood very closely. It’s held in place by a thin string of silk on one end of the chrysalis and a silk pad at the other. That’s where the caterpillar spends the winter. There’s a remarkable photo of a Tiger Swallowtail’s chrysalis at the bottom of this Wikipedia page. Be sure to click on it to enlarge so you can tell where the bark ends and the chrysalis begins! My photo below shows the tiny hairs on the swallowtail’s wings – the closest my camera has ever come to a Tiger Swallowtail, I think.

The blue spots at the bottom of her rather ragged wings tells me that this is a female Tiger Swallowtail. Perhaps sipping at thistles has taken its toll on her as well as the Giant Swallowtails?

Three small Lepidopterans played a role in the color scheme. Like the members of the Swallowtail family (Papilio),  a female Black Swallowtail (Papilio polyxenes) found Bull Thistle a good choice for nectar in this transition time just before the Goldenrods reach their full glory and other fall asters emerge. I admit I appreciate the non-native Bull Thistles more this year, having seen how much sustenance they’re providing after a torrid July brought an earlier end to the bloom of so many wildflowers. A Clouded Sulphur (Colias philodice) paused on the drying leaves of a Queen Anne’s Lace. I’ve wanted to see a chrysalis of these small butterflies ever since I read it described as “yellow with a pink zipper”! No luck yet.  And the Ctenucha Moth (Erebidae family) did a fine job of contrasting its black wings with the yellow Grass-leaved Goldrod.

So much gold!  And I didn’t even include the gold and black bumblebees, wasps and honey bees foraging among this late summer landscape! Such riches, eh?

Late Summer Serenity

Sometimes life does come full circle.  Standing at the edge of the meadows at Charles Ilsley Park with sunlight falling on a fluttering, buzzing,  golden landscape, I could feel the deep sense of calm and quiet that I relished in our township in my childhood. On just such a morning then, I would stand on the sturdy limbs of a rugged old tree overlooking a wild pond or spread my blanket in the short grass near the shore and breathe in the comforting scent of warm earth and grass. I feel so fortunate as an older woman to still experience that certainty of being part of something big and beautiful that nature offers all of us if we take the time. I wish that for you, too.

Postcript: Watch for More Ilsley Photos!

Of course, Charles Ilsley Park offered me much more than gold and black in its rich diversity:  a wet spot in a field suddenly blooming with red and blue wildflowers, a fuzzy brown House Finch fledgling peeking through the greenery,  lavender blossoms emerging from the seedbank where a moist swale was restored, a dramatic Darner dragonfly decorated in a pattern of blue and green and more. So rather than extend this blog, I’ll create a shorter photo blog later this week to fill in the rest of the color palette at Charles Ilsley Park.  Hope you can drop by!

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

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

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

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

Fledglings Venture Forth into Sunny Meadows

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

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

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

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

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

Dragonflies and Damselflies Hover and Dart in the Meadows

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

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

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

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

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

The Seed Bank Awakens as Restoration Begins

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

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

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

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

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

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

Butterflies Arrive – but Not Enough for Me, Yet!

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

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

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

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

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

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

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

On to the Pond and Its Frog Song

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

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

A male Green Frog among the duckweed at the Center Pond

Frog “talk” this July:

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

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

Into the Woods

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

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

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

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

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

An Eastern Towhee singing his “Drink your Teeeeeea” song at Cranberry Lake Park after one eluded me at Bear Creek

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

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

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

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

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

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

Bear Creek Marsh – Wet, Green and Full of Life

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

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

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

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

Buttonbush Blossom in bloom!

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

A Green Heron among the cattails at Bear Creek Marsh

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

A Snapping Turtle cruising along in the marsh.

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

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

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

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

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

Stewardship Fosters Nature Here – and Far Beyond the Township

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

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

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

Beauty in Every Season: A Year-End Review of our Parks and Natural Areas

Oakland Township Stewardship Manager Ben VanderWeide and I both got inspired by the idea of a year-end reflection on some of  the remarkable sights in our parks and natural areas over the last year. Nature excels in surprising and delighting any curious observer with its ability to come back from adversity, in some cases to even thrive in difficult circumstances. That ability to keep on growing and creating in the face of any obstacle can be a great inspiration in challenging times.

So as the snow falls, please sit back in a comfortable chair with a warm drink and savor  some highlights from the four seasons of 2017 here in Oakland Township.

Winter 2017: Serenity Rises as the Snow Falls

The Tree Line Between Two Prairies, Charles Ilsley Park

Sometimes we just need a little less hubbub after the holidays and the parks provide a  peaceful escape. In general, the only sounds are the wind in bare branches, the occasional calls of the year ’round birds and the tapping  of energetic woodpeckers foraging in the tree bark. And other times,  when we feel  a bit house-bound and crave crisp air on red cheeks,  a winter walk provides little discoveries unavailable in other seasons. During one deep freeze last winter, the weekly birding group stepped out on the ice at Cranberry Lake to inspect a beaver lodge. And a few weeks later,  I plopped down in the snow for a closer look at 3-D ice dendrites standing upright on a frozen puddle! Folks enjoyed the fine skating rink at Marsh View Park, but some who fancied wild surroundings skated on Twin Lake. On sunny winter days, shadows are always sharp and any spot of color, like the brilliant red of a male cardinal,  catches my  eye in winter’s clear, white light. Hiking in winter can be wonderful; just be sure you’re bundled up for it! (Click on pause button for longer captions.)

Spring 2017: Buds, First Blooms, Migrators Flying in by Night and the Ebullient Symphony of Courting Birds and Frogs

Golden Alexanders carpet the woods near the Wet Prairie along the Paint Creek Trail

Ah, mud-luscious spring! The tiny Chorus and Wood Frogs thawed out after their winter freeze and sang lustily from vernal ponds. In early spring, the birders spotted a crayfish at Bear Creek who’d climbed out of her chimney with eggs under her tail and was lumbering toward the pond. Some spring avian migrators quickly passed through, and we bird watchers were lucky to spot a few special visitors. An unusual American Pipit appeared before my camera lens one afternoon at Gallagher Creek Park on its way to its breeding grounds in the far north. While others, like the Tree Swallow or the Eastern Meadowlark, settled in for the summer to raise their young. After last year’s controlled burn, native Lupines appeared along the Paint Creek Trail. And in May, Ben spotted a rare sight, a frilly spread of rare Bogbean flowers in a kettle wetland at Bald Mountain State Recreation Area off Kern Road. Snow melt and bright green buds always offer an irresistible invitation to come out and join the bustle and music of spring!

Summer 2017: Butterflies Galore as Restored Prairies Began to Bloom

East Prairie Ilsley 2017 (1)
Member of the birding group at Charles Ilsley Park in July

Summer! The very word conjures up a coloring box assortment of butterflies hovering over prairie wildflowers. Birds constructed their nests and later wore themselves out feeding noisy, demanding fledglings. We birders particularly enjoyed close looks at a male Rose-breasted Grosbeak sharing egg-warming duties near a Bear Creek path. The birders laughed in surprise watching  a passive/aggressive pair of Canada Geese successfully discourage the presence of a Green Heron by simply swimming uncomfortably close to it.  A family ambled along a path at Draper Twin Lake Park, headed for a morning fishing expedition.  The birding group, binoculars in hand,  spotted an Indigo Bunting while walking the new paths through the prairies at Charles Ilsley Park, increasingly spangled with colorful native wildflowers as restoration proceeds. A Great Horned Owl stared at the delighted birding group through a scrim of leaves near Bear Creek marsh.  Every path in the township hummed with life during the summer months. But that’s what we all expect of summer, right?

Autumn 2017:  Birds Departed South, and Fall Wildflowers Bloomed

Autumn color at Cranberry Lake Park

Tundra Swans flew in formation overhead,  as migrators of all kinds, like the Hermit Thrush, rode the north wind down to southern climes. But as they departed, nature offered a consolation.  Many native wildflowers bloomed in the cool weather as they faithfully do each year. Asters formed carpets of color everywhere, from meadow to marsh! At the Wet Prairie on the Paint Creek Trail,  tiny Ladies Tresses orchids, Grass of Parnassus with its delicately striped petals, and vivid purple Fringed Gentian intrigued me again by emerging in the chill of early autumn. Native bumblebees pushed their way into Bottle Gentian flowers at Gallagher Creek Park and the Wet Prairie. Butterflies still sipped nectar from late fall blooms. The birders identified ducks of all kinds assembled in rafts on Cranberry Lake. Rattling cries alerted me to the presence of  Belted Kingfishers who scouted for prey at  both Bear Creek’s pond and Cranberry Lake. Ben dipped his net into a marsh at Charles Ilsley Park to show us tadpoles that overwinter on the muddy surface beneath the water. So much life as the year 2017 began to ebb!

Parks Full of Life All Year ‘Round. Aren’t We Lucky?

As a direct result of the foresight of township residents who have supported the Parks Commission and land preservation, native plants, wildlife, birds, and a beautifully diverse combination of habitats are being restored and preserved in Oakland Township. I want to share my appreciation for that foresight and for the hard work and knowledge of Ben VanderWeide (my kind and able supervisor and editor), other parks volunteers, my fellow birders and park staff.  And at the end of the year, I thank all of you who read, comment on and/or follow Natural Areas Notebook. It’s wonderful to be learning more all the time about the natural world – and then to have this opportunity to share what I’m learning with all of you. On to 2018!

Photos of the Week: Native Wildflowers and Butterflies Flourishing at Stony Creek Ravine

 

The photo on the left shows the path into Stony Creek Ravine Nature Park last summer when it was lined with invasive shrubs taller than my husband’s head! On the right is the path this year lined with Bee Balm (Monarda fistulosa), a native wildflower. Park neighbors recall that this area used to be an open field. Work started last autumn to remove invasive shrubs, giving native plants a chance to flourish as they once did. And the flowers have taken advantage of it! Below is a slide show of the native plants now blooming and the amazing collection of butterflies enjoying their nectar. Wait until you see the Giant Swallowtail (Papilio cresphontes)!  It’s as big as some tropical butterflies!

The path leads to the dramatic ravine and an open oak forest. You’ll hear woodpeckers, warbling vireos, indigo buntings, towhees, goldfinches and more within this park. A remarkably impressive 60 acres which will only get more interesting over time!

Charles Ilsley Park: Our First Restored Prairie in Bloom! And Oh, the Butterflies and Birds!

 

The Eastern Prairie at Charles Ilsley Park
Blog post and photos by Cam Mannino

Charles Ilsley Park sways with grass and colorful wildflowers right now as restoration begins returning the rolling fields to the prairies they once were. The eastern prairie, featured this week, is breath-taking!   Butterflies dance in and out of native Black-eyed Susans, bees hum, grasshoppers leap at your feet and dragonflies swoop above the Yarrow and Bee Balm. Birds perch and forage at the trail edges and sing from the woods.

These former farm fields, once full of invasive and non-native agricultural plants, are gradually being restored to provide for the birds, insects and other wildlife that historically nested and foraged here. A new path through the thirteen acres of the eastern prairie now provides a perfect quiet stroll on a sunny morning or afternoon.

Birds are Plentiful, Colorful and Sometimes Difficult to See

At this time of year, adult birds are busy feeding and over-seeing either nestlings or fledglings. So they’re deep in the leaves, high in the sky, or down in the grass, foraging for whatever will feed the young. Here’s a graceful female Baltimore Oriole (Icterus galbula) with seeds in her beak approaching her nearby nest hidden in a clump of leaves that hangs right over the trail as you enter the park.

Earlier in the summer, the bird boxes along the trail into the park were busy places! A House Wren (Troglodytes aedon) took over a rather dilapidated one.  You’ll notice in one of these pictures, the wren is pecking at a spider web. Cornell Lab says that wrens often put spider egg sacs into their nest box so the spiders will rid it of mites! (Click on arrow for slide show; use pause button for captions.)

The Tree Swallow (Tachycineta bicolor) spread its huge wings as it swooped in and out feeding its mate or young in June. Now the box seems to be just a stop-over spot as it soars and dives in the meadow beyond.

Look at the size of those wings!
And look at those wings folded!

Thanks to Laurie Peklo, a member of the birding group who cleaned out the nesting boxes this spring, the Eastern Bluebirds (Sialia sialis) also found a home at Ilsley again this year.

A few weeks later, we saw a Bluebird fledgling in a tree, perhaps the male’s offspring. Baby bluebirds take a while to turn really blue, so I’ve also included a photo of a bit older one begging in our front yard. (Click on photos to enlarge; use back arrow to return to blog.)

When you reach the sign about Prairie Restoration, you’ll see that the center of the park is brown and mowed. Don’t worry.  Ben VanderWeide, township stewardship manager, and his crew are just preparing the ground so that in the fall, it can be sown with native prairie plants – just as the eastern prairie was planted two years ago, and the north and west were planted last year. In a few years, we’ll have close to 50 acres of prairie in this park!

On every recent visit, a male Common Yellowthroat (Geothlypis trichas) has sung from the bushes on the hill in the center field. That’s why Ben left the greenery there when the field was prepared for prairie planting – to protect their young. The photo below, was taken in the spring when one male came a bit closer and really belted out his “witchedy, witchedy” song!

The “witchedy” song of the Common Yellowthroat can still be heard at Ilsley, but in spring he really threw back his head and SANG!

Field Sparrow (Spizella pusilla) foraged in the grass of the trail on one of our birding walks. Its pink-ish beak matches its pink legs – an easy field mark for these little birds. Ben describes their rolling song as a bouncing ball.

Young Chipping Sparrows (Spizella passerina) and their elders forage there as well. Thanks to birder extraordinaire, Ruth Glass,  for the identification! (Click on photos to enlarge.)

Ruth also identified the rather scruffy  Eastern Wood- Pewee fledgling (Contopus virens) below.  

A rather scruffy-looking, juvenile Wood-Pewee

We birders heard an adult one singing in the woods near the eastern prairie last week, but didn’t see it – as is often the case with singing Pewees.   Luckily, one landed near our deck at home a few weeks ago, singing its name on a rising note  – Pee-weeee! Nice to see one up close and personal!

Indigo Bunting

In a clump of trees on the south side of the east prairie, an Indigo Bunting (Passerina cyanea) sang from a very tall snag on my last three trips to Ilsley. He must have a nest nearby. He’s so far up, singing his song in phrases of twos and threes, that it’s hard to even see he’s blue!

But my husband and I were lucky enough to have one fly down to a small tree near us while walking at Addison Oaks about ten days ago. Such a glorious bird!

An Indigo Bunting – one of the rare moments when I’ve seen one up close!

As some of the birders exited the eastern prairie last Wednesday, they saw a very unusual bird, a Yellow-throated Vireo (Vireo flavifrons). I didn’t get a look before it flew – so here’s a lovely photo from a generous Creative Commons photographer at inaturalist.org, Donna Pomeroy.

We also saw the Red-eyed Vireo (Vireo olivaceus) again. Here’s a photo of this elusive bird by gifted local photographer, Bob Bonin.

Prairie Wildflowers – What a Sight!

Black-eyed Susan cover the northern edge of the eastern prairie as you walk in

In 2015, the eastern prairie was sown with native seed acquired through a grant from the U.S. Fish and Wildlife Service. It will take three or four summers of careful stewardship for these native, drought-resistant prairie plants to grow deep roots and reach full bloom. Although this is only their second summer, the native wildflowers are already carpeting the prairie with color.

Ben mowed the field once this year already and will mow once more in August.  This relatively high mowing reduces the seed production of annual and biennial plants (like burdock, thistle and Queen Anne’s Lace) and allows sunlight to reach the prairie plants while they are small and growing roots. Look  at just of few of the native wildflowers already coming up!

And we still have autumn flowers to look forward to!

That Carpet of Prairie Wildflowers Brought All Kinds of Butterflies!

What a glorious sight! All over Ilsley’s eastern prairie, butterflies float and flutter in and out of the colorful tapestry of native plants – sipping the nectar and enjoying the sunlight. The birders sighted a relatively uncommon black butterfly called the Spicebush Swallowtail (Papilio troilus), though it took a lot of talk and research to identify it correctly! Luckily, the next day I saw the very similar Black Swallowtail (Papilio polyxenes) and was able to study the photos to spot the distinctions between the two. Here’s a swallowtail identification link I found very useful.  (Note that on this site,  the butterflies’ names are above rather than below the photos, which can be confusing at first.)

This is the male Spicebush Swallowtail. Notice that he only has white dots along the edge of his forewing, a faint line of pale blue dots above and a wash of blue (or blue scaling) on each hindwing.

A male Spicebush Swallowtail, a fairly rare butterfly to see in our area though they do frequent southern Michigan

The Black Swallowtail has a larger second (or postmedian) row of  yellowish spots above the row at the edge of its forewings and its more intense blue is contained in spots, rather than a wash of blue. It has a complete orange dot on each hindwing. This is the female, I believe, since her orange dots have a black center and the male’s are solid orange. Whew! Glad I had photos to help me!

The female Black Swallowtail, also at Ilsley, looks very similar to the male Spicebush.

My husband and I saw a third swallowtail flying high into the trees at Ilsley – the Eastern Tiger Swallowtail (Papilio glaucus). Here’s a photo from Bear Creek several years ago, just to remind you of its beauty, too. The female of this species can also be black!  But that’s for another blog…

One hot morning, four different Monarch butterflies (Danaus plexippus) drank from blossoms on the Eastern Prairie. They didn’t leave their wings open for long when they settled; they only used them to move from bloom to bloom. Perhaps closed wings kept them cooler, since less sunlight would fall on their closed wings than on open ones. I’ve learned that dragonflies tip their bodies vertically to stay cool on really hot days for that reason.

Some of the birders spotted a Red Admiral (Vanessa atalanta) one Wednesday morning when I was off looking at the Spicebush Swallowtail.  So here’s an older Bear Creek photo of one of those also.

Look for Red Admirals at Ilsley too!

On my last trip to the park, I saw a finger-nail-sized, triangular-shaped, white butterfly that I could not identify (help anyone?) and a tiny orange one that I believe is a Delaware Skipper (Anatrytone logan). To assess their size, consider that the little white one is under a Daisy Fleabane and the orange one is on a blade of grass! Interesting things come in small packages, eh?

A Spray of Tiny Grasshopper Nymphs,  a Nice Big Carolina Locust, and a Widow Skimmer Dragonfly as well

On the path that crosses the center of the Eastern Prairie, you’ll see – and hear! – hundreds of tiny grasshopper nymphs jumping off the path. They sound like rain falling on the taller grass stalks! Only about an half inch long now, they’re hard to identify. My guess is they’re Red-legged Grasshoppers (Melanoplus femurrubrum)The larger one in the slideshow below is definitely a Red-legged but it’s still a nymph, too. These guys molt 5-7 times before reaching adulthood. The brown Carolina Locust (Dissosteira carolina) is much bigger, about 2 inches.

Of course no prairie is complete without dragonflies! Female, or possibly juvenile male, Widow Skimmers (Libellula luctuosa), with yellow abdominal stripes, hunted above the greenery last week. Adult males eventually develop a white wing band next to the dark one and their brown abdomens take on a bluish-white sheen as they mature.

Step by Step, Restoring Our Natural History

Eastern prairie at Charles Ilsley Park.

We all love local history, so it makes such perfect sense to restore our natural areas, too. At Charles Ilsley Park, we have an opportunity to see what our township looked like before European settlement, when Native American tribes lived on the rolling oak savannahs covered with tall grasses, wildflowers and widely spaced oaks. Even more importantly, natural areas restoration re-creates at least some of the rich diversity of plants, insects, birds and other wildlife that historically shared our green corner of the world. We’re on our way now to something very special here in Oakland Township.  Come have a look!
