Cranberry Lake Park: Here Come the Migrators, There Go the Hibernators

 

New England Asters against a background of goldenrod at Cranberry Lake Park

Birds and butterflies flock to Cranberry Lake Park year ’round. The wide range of habitats there – a lake, wooded wetlands, huge meadows and acres of forest – provide food and shelter during the  summer for a wide range of different species. And migrators make it a regular stop-over in the spring and fall, this autumn being no exception.

Last week, little warblers flitted from limb to limb, keeping the birding group busy trying to spot them all by eye or ear. And in the meadows, the special “super-generation” Monarchs that hatched in late summer sipped from and floated above the asters and goldenrods before beginning their long migration to their wintering grounds in Mexico.

Migrating Birds Ride In, While Local Fledglings Bulk Up

A Sky Full of Migrating Broadwing Hawks at the Hawk Fest in Canada, 2018

When a north wind blows in the dark of night, getting out to the meadows in the morning can be a rewarding experience. Warblers and other migrators from farther north fly and float in using those winds to support them. As migration begins, being partially carried by the wind on a dark night saves energy and also avoids hawks and other predators that fly in the sunlight.

The birding group heard and saw the first flush of these seasonal nomads on their September visit to Cranberry Lake Park. Our first encounter was with a busy Black-and-White Warbler tracking up, down and around tree trunks on the Hickory Lane that runs down the western edge of the park. A tiny bird moving fast in dense shade meant that none of the birders got a decent photo. But since these beautifully patterned warblers wear the same plumage fall or spring, here’s a springtime shot when foliage was less of a problem!

The Black-and-white Warbler moves around branches much like a nuthatch.

Unfortunately, I missed most of the warblers on the Cranberry Lake Park bird walk by suddenly feeling ill. So fellow birder and fine photographer Joan Bonin was kind enough to share a few of her photos with me! Thank you, Joan! The group spotted a Magnolia Warbler (Setophagia magnolia) in its fall plumage, which as you’ll see in my photo on the right below is a lot different from its spring courting colors! It’s headed for the Bahamas like the Black-and-White. I hope the devastating hurricane there doesn’t mean trouble for them. Best of luck, little birds!  [Click on photos to enlarge; hover cursor for captions.]

Joan got a shot of a Black-throated Green Warbler (Setophaga virens) which is also headed to the Bahamas. It too wears less flashy plumage in the non-breeding season.

Ben caught sight of a  Chestnut-sided Warbler (Setophaga pensylvanica). Using his description and The Warbler Guide by Tom Stephenson and Scott Whittle, I think it probably was either a female in fall plumage or a first year male or female, because it had a clear breast with no chestnut streaks on its side. Since no one got a photo, I found one from a  generous photographer who uses the name “thejasperpatch” at the iNaturalist.org website. Thank you!

The male Chestnut-sided is one of my favorites because of its varied color and pattern. These tiny birds are headed for Central or South America to hang out with a flock they forage with every year – much like human friends who meet up in Florida each winter! Here’s my photo of a male prepared to charm the ladies in his spring plumage.

The Chestnut-sided Warbler spends each winter with the same group of tropical birds in Central or northern South America .

Ben also heard the slightly rough-edged,  two or three note song of the Yellow-throated Vireo (Vireo flavifrons), but the birders could never spot it in the thick foliage. Vireos often accompany warblers on migration. This one was probably planning to spend the winter in the Bahamas too, though they also winter in Cuba. The yellow “spectacles” are one of its distinguishing features. Here’s a photo by fine photographer BJ Stacey at iNaturalist.org .

Fledglings need a bit more sustenance before heading south. Before I departed on birding day, I got a quick photo of a  juvenile Eastern Towhee (Pipilo erythrophthalmus). It jumped excitedly from branch to branch, waiting for its parent, who periodically flew in to quickly stuff food in its beak. According to the Stokes Guide to Bird Behavior (Vol. 2), adult Towhees feed their fledglings for about a month after they leave the nest. At first the young stay in dense foliage, then gradually wait in more exposed places like the one in the photo below. Shortly, this young one will join with other juvenile Towhees to eat and hang out together like any adolescent. Fortunately, understanding adult towhees will allow them to cross their territories to do so.

A juvenile Towhee waited anxiously for its parent to bring food.

A week earlier in the same area, my husband and I had heard a male Towhee making his territorial “wheeet” call. When we spotted him, he gave us a sharp warning glance. I wondered at the time if his young were nearby. Maybe that alert male was the hard-working parent feeding the youngster that we birders saw a week later. I’d like to think so.

The Towhee went on alert once he spotted us.

On a cool, wet morning, a fledgling House Wren (Troglodytes aedon) perched on its own, looking out across a meadow. Other young wrens called to one another farther along the trail, so this one was probably waiting for an adult occupied with feeding its siblings. Before they migrate, wrens become quiet and remain hidden in the greenery frequently where they winter in the southern Gulf states and Florida. Southerners miss out on the male’s glorious spring song. Aren’t we the lucky ones?

A Wren fledgling appeared to be out on its own one cool wet morning but it’s likely that its parent was nearby, feeding its siblings.

Joan Bonin also snagged a photo of a  Broad-winged Hawk (Buteo platypterus) who was probably headed south toward the tip of Florida or Cuba. In autumn, huge “kettles” of these birds with thousands of individuals make their way south together. (See photo of a “kettle” at the top of this section.) Two birder friends and I saw a huge circling flock last year at the Hawk Fest in Amherstburg, Ontario, though this year the festival was canceled at the last minute  by a  storm severe enough to bring down trees. All this severe weather is a serious threat to migrating birds!

Monarchs Everywhere on a Cool, Autumn Morning!

The migration of the “super-generation” Monarchs is well underway. These heroes of the insect world – the last generation of Monarchs to hatch here in the upper Midwest and Northeast  – will live for 8 months, instead of the 5-7 weeks of all other Monarchs. They make the entire two-month journey of 3,000 miles to Mexico, spend the winter, and then fly back north to mate. There they lay the eggs for the first of the 4 to 5 generations of short-lived Monarchs who will successively produce their progeny, eventually ending this relay in Michigan each spring.

A Monarch, its proboscis ready for its next sip, flies above the Showy Goldenrod.

Alone at the park on a cool, wet morning, I saw twenty-one Monarchs in my first ten minutes! I stopped counting, took a few photos and then just enjoyed the sight of them slipping up out of wet greenery where they’d spent the night. They shivered upward, shedding dew, looking like vivid autumn leaves reversing their descent. It seemed that with every step I took, more of them rose from the moist meadow. A peaceful, quite magical sight. Here’s a short slideshow of just a few of them on the plants on which they’d rested the night before.

Monarchs were feeding close together as in this photo with two Monarchs in the foreground and one that’s just an orange blur in the background. Aren’t they just spectacular in their golden setting? What beautiful, delicate and surprisingly tough long distance athletes they are!

Other Wings Over the Meadows

The dragonflies and their slimmer relatives, the damselflies are on the wing in late summer and early autumn, too. In August, we saw a dragonfly that was new to me, the Slaty Skimmer (Libellula incesta), with a dark blue body and black head. It was above the lake trail which is lined with wooded wetlands, this dragonfly’s favorite habitat, according to the Odonata Central website. Ben got the best photo of it.

This Slaty Skimmer perched in the open, probably trying to attract a mate.

Meadowhawk dragonflies (genus Sympetrum) mate and lay eggs in July and August so they are plentiful right now. Determining a specific species in this genus is not possible unless you’re an expert with one in hand. But the males are almost always red and females and juveniles are usually yellowish brown or black and many have chevrons on their abdomens.

I was fortunate to get an identification on one Meadowhawk I saw because it had some distinctive features like yellow legs, a generally unmarked thorax and a scoop-like spatulate end to its abdomen. This is likely a female Autumn Meadowhawk (Sympetrum vicinum) as identified by people more experienced that I on the “Odonata of the Eastern United States” Facebook page.

An Autumn Meadowhawk rests in the sunlight on a September morning.

According to the Minnesota Dragonfly Society website, “Some dragonflies…point their wings forward and down in order to reduce exposure to sunlight and, perhaps, to reflect light and heat away from their bodies.” On really hot days, they’ll point the tip of their abdomen straight up toward the sky to have as little exposure to the sun as possible. Getting warm or cooling down take some acrobatics from these cold-blooded creatures!

Damselflies, another member of the order Odonata, are always busy in the summer and early fall at Cranberry. Unlike dragonflies who generally rest with their wings spread outward, most damselflies rest with their wings closed.  One family of damselfies, the Spreadwings (family Lestidae), cling to plants with their wings just slightly spread. This Spotted Spreadwing (Lestes congener) at Cranberry Lake Park in September shows this common wing position for spreadwings. How about those eyeballs!

I love the big, blue eyes on this Spotted Spreadwing damselfly!

The female Slender Spreadwing (Lestes rectangularis) can almost disappear with its clear wings and its unusually long, gray-to-black body, especially since it loves the shade.

Slender Spreadwings love the shade and that’s where I found this one.

Now admittedly, the Tussock Moth’s Caterpillar (Euchaetes egele) isn’t fluttering just now, but it plans to! Of course, it will need to chew on quite a lot of Milkweed before it builds its cocoon and waits until spring to transform. The adult moth’s chunky yellow body lined with black dots  is hidden under a pair of subtly elegant beige wings. I’m still on the hunt for the moth (which you can see at this link), but for now, I’m enjoying the floppy, mop-head look of the black and orange caterpillar.

Milkweed Tussock Moth caterpillars will soon spin a cocoon where they’ll spend the winter until they emerge with wings in the spring.

 

Amphibians Still Visible, but…Hibernation Awaits!

A small Green Frog (Rana clamitans) at the edge of Cranberry Lake in September will soon settle on the muddy bottom and breathe through its skin throughout the winter.

In August, I saw a lot of tiny amphibians near Cranberry Lake! The young Leopard Frog  (Rana pipiens) my husband I saw will shortly be heading for the bottom of the lake to spend the winter just as the Green Frog above does – on top of mud on the lake bottom, breathing slowly through its skin.

The Leopard Frog has been in decline since the 1980’s but can be see in several of our parks.

When the temperature drops, the tiny Wood Frog (Rana sylvatica) that Ben picked up on the bird walk will travel upland to hibernate inside a log or under leaves. According to National Geographic’s website, once its body starts to freeze, its liver produces a kind of internal “anti-freeze,” a very sugary glucose solution which is then packed into the cells so they don’t collapse, like human cells do when frozen. The little frog will survive if no more than 67% of its body freezes. Its brain activity stops, its heart stops and it’s frozen solid! But in spring, it thaws and hops away! It can even tolerate our Michigan freeze-thaw-freeze cycles! By the first frost, this little one will be bigger and ready for the big adventure!

This tiny Wood Frog will freeze solid during hibernation this winter and thaw in the spring!

So many Eastern American Toads (Anaxyrus americanus) were springing from under our feet in August that we had to be cautious not to step on them! They often hatch simultaneously and may stay together for some time afterward. Once cold weather sets in, they can dig a hole up to 3 feet deep with their hind legs and essentially back into the hole, the dirt falling in to cover them as they get deeper. Then their metabolism slows as it does for all hibernators and they remain in torpor for the winter.

Eastern American Toads often return to their natal ponds year after year.

The tiny Gray Tree Frog (Hyla versicolor) is bright green when it’s young  (see left below),  but becomes gray, brown or green, usually with a black pattern, when it matures (right below). Though the mating season is over for them now, the males are singing in September anyway, especially when it rains. We hear one singing from an unused hood vent outside our kitchen window! Like the wood frog, it can survive when its body freezes, thaw out in the spring, and be just fine.

Fall Has a Special Kind of Excitement, Doesn’t It?

A Sheet Spider’s web between Showy Goldenrod at Cranberry Lake Park

We often think of the fall as brilliantly colored falling leaves – and of course, that’s coming. But in this early part of fall, as days occasionally turn crisp and nights get chilly, so much more is going on!

Spider webs bejeweled in dew shine in the morning sun as spiders prepare to snag more insects before cold weather begins.  Bright yellow goldenrods are now complemented by purple flowers, like New England Aster. Acorns and hickory nuts tumble to the ground and are quickly stored away by squirrels and chipmunks. Large hatches of tiny, late season Red-legged Grasshoppers spring from the grass below our feet as we hike the trails. They must hurry to grow, mate and lay eggs before the ground hardens.

Some birds disappear for a while to change into their winter colors. Others relinquish the territorial fierceness of breeding season to gather in huge flocks, flying in formation or whirling high overhead. Small ones fly singly through the dark, only stopping to eat and rest, before moving on.

And we humans stock our larders with summer produce – berries in the freezer, peaches in bottles, apples at the fruit stand. We repair a leak in the roof, wash the dust off the storm doors, pull jackets and sweaters from the backs of closets – or make arrangements to pack up and migrate south with the birds. All of us animals, human and otherwise, know that as day and night equal out at the equinox, preparations must be made! And so it begins….

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 male Red-winged Blackbird with a worm or caterpillar for his nestlings and some pollen on his head!

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!

American Bur-reed cleans our waterways by storing the nitrogen and phosphorus in run-off.

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.

THIS WEEK AT BEAR CREEK: The Drama of Drought and Downpours

Western Slope BC August

Blog posts and photos by Cam Mannino

Late summer is always a time of transitions, but this year was particularly dramatic. Bear Creek’s meadows baked for weeks under a blazing sun. The marsh dried completely, stranding an over-heated young  snapper that struggled through a tangled mat of exposed vegetation. Heat finished off blossoms as some wildflowers began to seed earlier than usual. And then in mid-August, the rains came – downpours, thunderstorms and off-and-on showers. You could almost hear the gulping of plants and trees swallowing the moisture through their roots. Snappers again cruised just below the shallow waters of the marsh. Life rallied.  As always, nature just coped and moved on.

Life in the Hot Sun of the Old Fields

The Old Field on the western edge of Bear Creek is quieter now. Mating season has ended (except for the Goldfinches), so birdsong has diminished. But one hot, sticky morning, an Indigo Bunting (Passerina cyanea) threw back his head and let loose his double-phrased song from the highest branch of a tree – a favorite perch for male Buntings.

An Eastern Phoebe (Sayornis phoebe) seemed to be listening to its neighbor as it rested between forays over the baking meadows, trying  to snatch a few unsuspecting insects.

Nearby, an Eastern Phoebe listened as the Indigo Bunting sang.

A juvenile Yellow-bellied Flycatcher (Empidonax flaviventris) posed quietly among the branches of smaller trees on the Western Slope. Expert birder, Ruth Glass, tells me that this little bird probably arrived from Canada or northern Michigan and is now migrating down to the Caribbean. Quite an adventure for a small bird!

Near the moist bottom of the slope one steamy morning, I spotted a lump on a leaf.  A newly metamorphosed Gray Tree Frog (Hyla versicolor) was sleeping on a Common Milkweed (Asclepias syriaca). I’m afraid I woke it with my camera. The U of M’s Bio-kids website says they are “almost always bright green right after metamorphosis [from tadpole stage] and they stay this way for some time before taking on their adult coloration.” These frogs can sleep in the open during the day, using their camouflage to protect themselves; they don’t dehydrate quickly like other frogs. Isn’t it just the best little creature?

While birds foraged from the trees, the insects below braved the blazing sun  to look for their own sustenance. In the grass on the Western Slope, a Common Buckeye butterfly (Junonia coenia) seemed to searching the bottom of grass stems. I’ve read that they sip nectar but often look for fluids in moist earth. Perhaps it was hoping for dew on a hot morning in August.

Higher up on the western path, where the land was drier, beetles probed blossoms looking for food. On the left, a non-native Seven-spotted Ladybug (Coccinella setempunctata) searched diligently for aphids, a favorite food. In fact, these beetles were brought here to combat aphids, but as a result, they’ve outcompeted our native ladybugs whose numbers have declined. On the right, a Soldier Beetle (family Cantharidae) may also be pursuing aphids, though it also eats pollen and nectar. (Hover cursor for captions; click on photo to enlarge.)

In the trees near the top of the Western Slope, a sparrow fluffed its feathers in thin shade. It’s hard to identify juvenile sparrows but with its pink feet and bill, I’m guessing this is a juvenile Field Sparrow who hasn’t yet reached full adult plumage when it will have a more distinct eye ring and a clear breast.

A Field Sparrow has a pink bill and pink feet so I’m guessing this is a juvenile whose breast plumage is still changing.

American Goldfinches mate in August, much later than other birds. On one hot visit,  a female repeatedly rode drying blossoms of Queen Anne’s Lace down to the ground to forage for seeds, perhaps to feed her young –  or her hard-working self! Unlike many seed-eating birds, the Goldfinches don’t switch to bugs when breeding. They are strictly vegetarian.

Nestlings of other birds are transforming into curious fledglings. One afternoon, a young, female Eastern Bluebird (Sialia sialis) perched high in a snag (standing dead tree), her spotted breast only halfway transformed into adult plumage.

Wildflowers felt the impact of the fierce sunlight. A Jewel Weed blossom near the pond dried in the heat, while others took its place in the dappled shade.  And up on the top of the southern hill, the Yellow Coneflowers (Ratibida pinnata) dropped their petals and began the seeding process in the dry heat.

Sturdy Prairie Dock blossoms, looking like little suns themselves,  began to dry out as well as they towered over the wilting Coneflowers.

A female Black Swallowtail hovered just off the sun-drenched Eastern Path, looking restlessly for just the right blossom. Folding its dark wings may help it cope with the sun’s heat.

Patrolling for food, a Ruby Meadowhawk dragonfly rested momentarily  on a leaf, its clear wings shimmering in the hot sunlight.

The northeastern edge of the Old Fields evidently stayed moist despite the  heat and several “wet-footed” plants took full advantage of the bright sunlight.  Joe-Pye (Eutrochium maculatum) spread its dusty pink blooms out across the field instead of appearing as widely distributed single plants as it often does here.

Joe-Pye flourishes off the Eastern Path.

Other native wetland plants fringed the same area.  The trio below includes bright pink Swamp Milkweed (Asclepias incarnata) with its green stems, Joe-Pye with dusty pink blossoms and purple stems and Boneset (Eupatorium perfoliatum) with its white blossoms and leathery leaves.

Below center, the native Bumblebee (genus Bombus) sips nectar from the Swamp Milkweed with its long tongue and on the left, is a closer look at Boneset. Odd name, eh?  Evidently early herbalists noticed the way the stem seemed to rise right through the clinging leaves reminding them of a splint around a bone. So its leaves were wrapped with bandages around broken bones. Native Flowering Spurge (Euphorbia corollata) on the right also thrives here as it does in various spots along the Paint Creek Trail.

Sheltering in the Shade

Near the wood edges, I found mammals and insects enjoying the shade.  Following a shining strand hanging before our eyes, my husband and I discovered a very tiny white spider escaping the bright sunlight on the underside of a leaf. I tried but couldn’t identify it, despite that wonderful design on its abdomen. We wondered if that brown ball was an egg sack. Anyone know this tiny creature’s name?

A tiny white spider, unidentified, sought the shade on the underside of a leaf next to what may be an egg sack.

And, as usual, damselflies moved in and out of the shade at the edge of the Oak-Hickory forest. I’m guessing,  based on its bright blue head, striped thorax, and very pale abdomen, that this one may be a female Bluet (genus  Enallagma) or a recently hatched one. But since there are at least 17 species of Bluets in the Midwest, I’m not sure which one this is. Again, I’m open to your ideas.

A White-Tailed Deer (Odocoileus virginianus) sat calmly on the shady site of a dried vernal pool, while her fawn dutifully hurried off into the bushes as I paused for the photo.

And an Eastern Cottontail paused in a shady spot along a trail one hot morning as well.

And Then the Rains Came…

What a relief when heavy rain came to refill the wetlands and ponds at Bear Creek Park! After watching  that young Snapping Turtle (Chelydra serpentina) struggling through vegetation in the dry marsh, it was a relief to see two Snappers feeding and cruising just below the surface in the cooling water provided by the rain.

 

The bright sun and rain caused Common Duckweed (Lemna minor) and Water Meal (genus Wolffia) – often mistaken for heavy algae – to form thicker mats across wetlands around the park. At the Playground Pond, I heard a plop! one afternoon and saw just the head of a Muskrat (Ondatra zibethicus) moving through the juicy green surface. Luckily, its ears close when it enters the water! When swimming, it uses its tail to propel itself with the help of its webbed back feet.

Once the Muskrat dove, I noticed other denizens of the Pond nicely camouflaged in duckweed and water meal as well.  Here are two turtles and a frog on a log decked out in greenery.

Quivering in the duckweed near the boardwalk made me look down to see a whole collection of small Green Frogs (Rana clamitans). Each of those individual spots on the leg  of the frog below is a water meal plant! Ducks do love this plant, by the way.  Sometimes they just dip their bills in and move along, scooping it up.

In the wetland just north of the Playground Pond, a particularly beautiful native plant is blooming in the moist shade, Cardinal Flower or Red Lobelia (Lobelia cardinalis). Last week when I took an out-of-town friend to the park and left my camera at home,  we watched a Ruby-throated Hummingbird (Archilochus colubris) sipping at a tall stalk of this scarlet beauty. I came back for its photo the following day – but no Hummingbird then, I’m sorry to say!

Cardinal flower single
Hummingbirds can be seen feeding at Cardinal Flower in the wetland just north of the playground.

We also spotted two Barn Swallows  perched quietly in nearby trees. No camera again! The next day, they were swooping madly across the meadows, their bills open, enjoying the swarms of insects that had hatched after the rain. One perched for a moment in a snag over the wetland and I got this quick photo of it from below.

As the water rose in the Center Pond, tiny  Painted Turtles (Chrysemys picta) appeared on nearly every log. Here’s a silver-dollar-sized one trundling along as it explores its world like any youngster.

This week, a Green Heron (Butorides virescens) dropped into the bushes at the western edge of the pond. It kept a close eye on the water, when it wasn’t actively preening with its long, extendable neck. Green Herons are expert hunters of both fish and frogs.  I wondered if the absence of July’s huge number of green frogs was attributable to the drought or this multi-colored fisher. (My apologies for the slightly pixelated photos caused by aggressive cropping so we could see it up close.)

Yes, it’s been a hot, sticky and then rainy summer. But we’re all in this together – animals, birds and plants. The natural world provided a gentle reminder that change, even dramatic change, is an inherent part of being alive. Summer may be waning now but the beauty around us isn’t. Surprises await our arrival every day, no matter what the weather.

 P.S.  More Native Beauties Blooming along the Paint Creek Trail!

The trick about blogging during the summer is that so much happens all over the township, all at once!  Keep an eye out for these special native wildflowers blooming for just a short time in the Wet Prairie on the Paint Creek Trail. The shallow water table in this meadow provides a perfect spot for these fire-adapted beauties. The field is dotted with the purple fireworks of Cylindrical Blazing Star (Liatris cylindracea), the striped elegance of Grass of Parnassus (Parnassia glauca) and the delicate, spotted petals of Mountain Mint (Pycnanthemum virginianum). Don’t miss them!

This Week at Bear Creek: Wildflowers Galore, a Damsel in No Distress, New Birds and Very Small Frogs

This week the native wildflowers are glorious!  You can start admiring them right in the parking lot!  Since Ben and his crew burned the center circle of the driveway, native wildflowers are sprouting there like crazy! And the native beds on either side of the shed are full of blooms.

I’ve enjoyed learning the common names of wildflowers in the last few years.  Knowing names starts a relationship with a plant in the same way that knowing a person’s name makes them more than a casual acquaintance.

This striking,  deep violet-blue native plant with long graceful leaves has an unfortunate name,  Spiderwort (Tradescantia ohiensis).   (People who came up with common names seemingly had no poetry in their souls and  must have thought it cured spider bites).  Look at this beauty up close!

Spiderwort, a native wildflower,  looks wonderfully exotic but has a pedestrian name which may refer to an earlier belief that it was a cure for spider bite.

There’s also this golden flower that I’d never seen in the circle until this year after the burn.  I love the buttery yellow glow and scalloped petals of Sand Coreopsis (Coreopsis lanceolata) and so does what looks like a hover fly  whose abdomen is smeared yellow with its pollen.

coreopsis w hover fly2
I believe that’s a hover fly with his abdomen and legs smeared yellow with pollen on this native Sand Coreopsis right in the center of the driveway at Bear Creek.

In the park and in the circle is a happy yellow flower called Golden Alexanders (Zizia aurea). It does well after a burn because our part of Michigan used to be prairie. Prairie and other grasslands across North America have burned regularly for thousands of years. Fires were either intentionally set by Native Americans or lit naturally by lightning.  This native plant is adapted to fire and loves sandy soil and sun.

 And look at the burgeoning overflow of beautiful Canada Anemone (Anemone canadensis) in the native flowerbed north of the shed!  Native plants can take a few years to really get going but once they do it is worth the effort. And clearly this was the year for these beauties.  Talk about ground cover!

While you’re admiring them, enjoy the many Hebard’s Green-legged Grasshopper nymphs (Melanoplus eurycercus) springing from leaf to leaf among the Anemone.  By August, they’ll have molted into much bigger grasshoppers.

Ben’s reported seeing some great birds in Bear Creek, some I have yet to see.  Cornell Ornithology Lab’s allaboutbirds.org wonderfully describes the beautiful deep blue Indigo Bunting (Passerina cyanea) as being “like a scrap of sky with wings. ”  This amazing small bird migrates at night, navigating by a single star.  The young learn their cheerful song from nearby males in their “song neighborhood” and these local songs can last for 20 years passed on by successive generations. They are tricky to photograph (as you’ll see below!) as they sing high in the treetops near woods in shrubby areas – like the northern end of the steep sloping path on the Southwest side of the park or in the center of the big loop at the northern part of the park.

Ben saw the smaller, darker Orchard Oriole (Icterus spurius) in Bear Creek.  I have a photo of the female at Bear Creek a couple of years ago but the only decent photo of the male I have was taken at our oriole feeder.  They’re here only a short time, arriving late and leaving early, sometimes as early as mid-July, for their winter home in Central America. So look for them soon before they are gone!

The male orchard oriole is smaller and more russet than the Baltimore Oriole which is more orange.
female orchard oriole
The female Orchard Oriole, like the female Baltimore Oriole,  is yellow rather than orange like its mate.

Ben also saw a bird at Bear Creek last week that I’ve never seen there – but I did hear one today at Marsh View Park.  The iris in the eye of the Red-Eyed Vireo (Vireo olivaceus) turns red when it matures so don’t be surprised when you click the link below and see a gray and white bird!  The amazing feature of these Vireos is that the male whistles his brief song incessantly from morning ’til night, sometimes repeating a song over 20,000 times in a day! Once you recognize it , you’ll know you’ve heard it in the woods for years.  So click here and then go down the page on the left to the “typical song.”

Those Green Frog tadpoles I mentioned last week are now very young frogs!  Look for them roiling the water in the pond near the playground.  They are still very small, their legs are not fully developed and some of them, as you’ll see in the photo below, still have stubs of tadpole tails that they haven’t yet absorbed into their bodies.  Like other creatures born in huge numbers, frogs serve as fast food for a lot of other species. Without lots of little frogs for nutrition, the predators that depend on them for food will be hungry. That’s one reason the declining numbers of amphibians is a concern in native habitats.

These young frogs are not fully developed yet and in fact the bottom one is still absorbing his tadpole tail into his body.

Watch for the Snapping Turtle too.  At the playground pond last Sunday, we spotted him  as a large oval patch of Duckweed moving steadily just under the surface of the water.  I imagine that he was using some young frogs as a quick snack.  Here’s a photo of one last year basking after a trip through the duckweed.

A sleepy little Gray Tree Frog  (Hyla versicolor), strictly nocturnal,  snoozed Sunday on one of the platform supports. Once grown it will generally stay high in the trees except when it comes down to breed. I imagine that’s why its skin looks so much like tree bark – good camouflage!

And what about those damsels in no distress?  Well I was referring, of course, to damselflies, those slim, elegant cousins of the dragonflies in the order Odonata.  Sunday this one flashed like neon blue morse code as it rested with its wings folded near the playground pond.  I’m guessing that it’s a Marsh Bluet ((Enallagma ebrium)) but again, don’t quote me.  Bluets are a big group of dragonflies and they all have only minor differences.

This damselfly, perhaps a Marsh Bluet, shines neon blue in the sunlight.

One of the dragonflies at the playground pond is almost comic in appearance!  I swear it has a kind of Mickey Mouse face!  Its precise but unimaginative name is the Dot-tailed Whiteface (Leucorrhinia intacta)and you can’t miss them! They’ll even accompany you down the boardwalk.

QUICK REVIEW:  New sightings of  species mentioned in earlier “This Weeks”

Evidently, the Green Heron is still fishing down at the Center Pond.  If you admire patience, speed and accuracy, this bird has it all.

Wow!  Have a look at one of the branches hanging low over the pond by the playground.  I hobbled over there with my walker last week and we spotted  the long narrow tube of an Baltimore Oriole nest among the branches.  Watch quietly and you’ll see the orange tail feathers of the female oriole as she goes head down into that tube to feed her nestlings.  She and the more colorful male foray out repeatedly gathering food, too and it’s such a close viewing spot, easily accessible for children.  Here’s a quick reminder of the nest shape, though the one at the playground pond is more hidden in the leaves.  (When I replace the camera I dunked in the marsh, I’ll try for a photo of the current one.)

A nest much like this one but hidden in leaves hanging over the playground pond contains Baltimore Oriole nestlings – with their mama head down feeding them.

And last week I featured the male Common Whitetail Dragonfly (Plathemis lydia).  Here’s a female Whitetail  who has settled on the rocks at the east end of the driveway circle.  She’s been there twice in the last week.  She lacks his bluish-white tail but has a lovely pattern down the edge of her rich brown abdomen.

Coming Attractions:

Bee balm/Wild Bergamot (Monarda fistulosa) will be blooming shortly in the native bed south of the shed, the circle in the driveway and out behind the center pond.  Only the leaves are out now but when they bloom, their lavender flowers will look a little like a frizzy hair dayBelieved to have medicinal properties (hence the name), native bee balm is indeed a balm to bees and butterflies who feed on it.

Native Bee Balm/Wild Bergamot is a good source of food for bees and butterflies.

The leaves of our native Common Milkweed (Asclepias syriaca) (which unfortunately is not as common as it needs to be) are sprouting everywhere in the park, including the driveway circle.    Before long, the leaves sprouting now will create fun landscapes like this:

milkweed bud tapestry
Milkweed leaves are sprouting around the park so their pompom-like flower balls should be showing in a few weeks.

One reason the number of Monarch Butterflies (Danaus plexippus) is dangerously low is that we don’t have enough Common Milkweed in many places.  Unfortunately, some nurseries are selling a non-native variety which can’t act as a host plant for the Monarch’s caterpillars.  And as meadows become lawns, more of our native Milkweed disappears.  We’ll explore a bit more about milkweed later in the season.

Summer is blooming: Birds feed their young, wildflowers unfold, dragonflies and damselflies dart above the ponds.  I hope you’ll find time this week to explore and relax in Bear Creek Nature Park.
