Charles Ilsley Park: Being Restored to Past Glories and Humming with Life

Panicled Asters line the entrance to the park
Blog post and photos by Cam Mannino

We tend to think of autumn as colored leaves and crisp air. But the prairies and meadows of the township parks celebrate fall with flowers. Many asters love cooler weather and right now the restored prairies of Charles Ilsley Park are dressed in white wildflowers, dotted with splashes of gold.  Butterflies and bees still flutter and hum among the blossoms and grasshoppers still spring like popcorn out of the grass as you walk. Birds, including occasional summer visitors headed south, eat the plants’ berries and seeds or snag a few insects from bare soil or tree limbs. The frantic growth of summer is indeed ebbing, but the park still bustles with life as it awaits the first frost.

Note:  Click here for a map of the park to help in visualizing the various trails and prairies described.

Entering Along the “Great White Way”

Panicled Asters line the trail on both sides as you enter the park

Walking along the mowed trail into Charles Ilsley Park before the latest heat wave, a nodding crowd of graceful Panicled Asters (Symphyotrichum lanceolatum)  stood on either side, like a crowd at a procession. Occasionally, a spray of New England Asters (Symphyotrichum novae-angliae) added a little royal purple to the view.

Just before sunset one afternoon, several migrating Palm Warblers (Setophaga palmarum) flitted among the branches of a tree along this trail. This little bird was probably on its way from Canada to Florida or the Caribbean. Let’s hope it finds its favorite foods and perches after the terrible storms there this fall!

Among some bare branches, a couple of Mourning Doves gave me a closer look.

And below, a female Downy Woodpecker (Picoides pubescens) drilled a dead branch  for insects, looking for a snack before retiring for the night.

A quick movement out of the grass onto a nearby tree turned out to be a Katydid (family Tettigoniidae) moving slowly along the trunk with its ungainly legs. Katydids are generally nocturnal and sing at night. I’m guessing this one’s a female because of what appears to be a sickle-shaped ovipositor for laying eggs. Aren’t her antennae amazing? Grasshoppers have short antennae, but katydid antennae are extravagantly long.

A female katydid came out of the field at sunset and began exploring a tree trunk.

The Central Meadow Will Soon Become a Prairie

The central meadow at Charles Ilsley Park is undergoing prairie restoration.

Don’t be dismayed by the browned surface in the central area of the park.  Like the other three sections already restored (east, north and west), the invasive shrubs and non-native plants have now been removed from this area. This fall, matted grass and leftover branches will be removed and the central area will be planted with native wildflower seed. Just as in the other three prairies, it will take 3-5 years for the native plants to fully bloom because as drought-adapted wildflowers, they need time to put down long roots before putting energy into flowering. But even now, life goes on in this brown landscape.

Blue is the first spark of color you’ll see in the restoration area – because the Eastern Bluebirds are everywhere! Many of them are using their former nesting boxes for perches as they fly down and forage in the soil and whatever grass remains.

This bluebird pair may migrate south or may choose to remain here over the winter.

Blackened stems, dead grass and bare soil make a perfect landscape for Killdeer (Charadrius vociferus) who prefer to nest and forage on open ground. They are known to nest on rooftops, golf courses, even parking lots! They scuttle up and down the restoration field at Ilsley, making periodic quick stops to see if they’ve scared up anything to eat. In autumn, Killdeer gather in small groups (I saw five ) as they migrate as far as Central and South America for the winter, though many choose southern Florida as well.

This Killdeer trio may migrate to Florida or Central and South America.

When Killdeer fly, they make a keening call and the feathers on their rumps, just above their tails, flash orange in the sunlight. Look for two flying Killdeer in this quick shot.

Can you see two killdeer flying with their orange rumps ablaze?

Another ground forager is still here but will also join small groups for migration. Northern Flickers (Colaptes auratus ) love ants, so they too are quite happy to forage in the newly re-sprouting grass or on the bare soil in this area of the park. You’ll often see 3 or 4 together on the ground.

In this season, Northern Flickers can often be seen looking for ants in the restoration area of the park.

Carolina Locust (Dissosteira carolina) flew up from bare earth as I approached the far end of the restoration area. I’ve never been able to catch a photo of one flying; they’re just too quick for me! So on the left is my photo of the locust on the ground, but on the right is a photo by Joshua G Smith at inaturalist.org who shows us its wing by gently holding the insect. You can see why these grasshoppers are often mistaken for butterflies when taking their short flights! (Click on photos to enlarge; hover cursor for captions.)

At the far end of the restoration area are a few bushes that form a line across the bottom of the north prairie. On all four trips to the park, an Eastern Phoebe (Sayornis phoebe) rested in the low branches of a tree there – a perfect perch for a flycatcher who actually prefers ground foraging  to catching flies!

The Eastern Phoebe actually prefers ground insects to catching flies, even though it’s officially a flycatcher.

With all those birds around, this immature Northern Brown Snake (Storeria dekayi) had better be careful! These harmless, little snakes (they don’t bite!) are born with a white “collar” around their necks and are either brown or gray.  As they mature, the collar disappears and the head is darker.  So I’m guessing this one is a juvenile on its way to getting rid of that collar!

Lots of Life on Three Prairies – East, North and West!

We’re gifted currently with three prairie plantings at Ilsley in various stages of restoration. The eastern and northern prairies are now in their second summer, the western prairie is in its first. All of them host a wide variety of wildflowers, butterflies, bees and birds.

Prairie Plants

Calico Asters (Symphyotrichum lateriflorum) have turned the eastern prairie white this fall.  The northern prairie, full of invasive thistles last year, is now covered with Brown-eyed Susans (Rudbeckia triloba), a species of Rudbeckia that I just learned about this year! The western prairie is cloaked in white Queen Anne’s Lace (Daucus carota) at the south end, and golden with Black-Eyed Susans (Rudbeckia hirta) at the north end. Natives like Indian Grass (Sorghastrum nutans) and some Big Bluestem (Andropogon gerardii) have returned to sway in the breeze above the eastern and northern prairies, which now have mowed trails. The western prairie trail grew over during the summer, but the soft plants make it easy walking. We’re on our way to 50 acres of prairie in this park! (Click on pause button for captions.)

Insects on the Prairies

Both Bumblebees (genus Bombus) and European Honey Bees (Apis mellifera) buzz quickly over the native blossoms, making the most of late fall nectar. One late afternoon, native bumblebees were driving honey bees off of some flowers with a quick dart toward them, while on other blossoms, honey bees were hassling butterflies.

A native Bumblebee and a European Honey Bee compete for the nectar in a non-native thistle.

Eventually, however, peace was restored and each found their own blossom on the Calico Asters.

At mid-summer,  the prairies were full of large butterflies – Monarchs and three kinds of Swallowtails. This month, though most of the larger ones are missing; only a few tardy Monarch butterflies (Danaus plexippus) sip at blossoms. The unseasonably warm weather may have prompted  them to tarry a bit longer than other Monarchs who began moving in September. We hope they make it to Mexico before the cold sets in!

A variety of smaller butterflies, some as small as your thumbnail, move restlessly among the blossoms on all three prairies. The Painted Lady butterfly (Vanessa cardui) is only 1.5-2.0 inches. It migrates some years and not others, but often winters in Mexico like the Monarchs. Its caterpillars eat thistle foliage and the adult butterflies love thistle nectar. This one was sipping daintily along with two other Painted Ladies on non-native Bull Thistle (Cirsium vulgare) on the northern prairie.

Three Painted Ladies enjoying thistle nectar, just as their caterpillars enjoyed eating thistle leaves.

The other small butterflies seemed endlessly restless, doing much more flying right now than eating.  I managed to photograph three – but the tiny Grizzled Skipper (Pyrgus centaureae) eluded me, so I’ve borrowed a photo from inaturalist.org with the permission of the photographer, Marian Zöller.

Birds Enjoying the Prairies

Birds of all sizes frequent these prairies during the year. Many of them, like the Tree Swallows,  have already begun their fall migration. But one evening at the far end of the eastern prairie, a solitary Sandhill Crane (Antigone canadensis) foraged, probably for just-hatched Red-legged Grasshopper nymphs (Melanoplus femurrubrum) that sprang in hundreds from the grass. Suddenly, it lifted into the air. I wonder if it, too, is beginning its migration to Florida or the Caribbean? I’m afraid I was too taken with its size, beauty and the snap of its huge wings to set my exposure accurately, but it was a lovely sight just before dark.

In an old apple tree on the edge of the western prairie, a flock of pale House Finches (Haemorhous mexicanus) pecked happily at the aging fruit. Usually House Finch males are much darker red, but the intensity of the color is determined by what they eat while molting. I have a feeling these were eating apples (or the bugs within them) instead of bright red berries!

A male House Finch eating bits of apple – or perhaps the bugs inside?

And a first for me in Oakland Township!  Last Sunday, a Bald Eagle (Haliaeetus leucocephalus) spiraled high into the air over the western prairie, riding upward on a rising current of warm air. What a very special moment to see this powerful bird peacefully enjoying the heat of the prairie on a quiet Sunday afternoon.

 The View from the Oldest Trees

Two huge oaks trees seem to anchor the past firmly in the present at Charles Ilsley Park. One stands at the south end of the center area that’s being restored and the other stands at the east end of the eastern prairie. The size of these old oaks with their huge trunks and spreading crowns means they’ve been here for hundreds of years, standing watch over the land. Pausing under the eastern prairie tree one afternoon, I took a photo of that tree’s “view” of the restored prairie.

View from under the huge oak at the east end of the Eastern Prairie

It pleased me to imagine that maybe that tree is “looking out on” on a prairie that’s beginning to look a bit like the one it “saw” when it was young so many years ago. And as we watched the bald eagle float above the western prairie, I wondered if it was seeing what its eagle ancestors saw from high in the sky long ago. Humans are such forward-looking creatures, always planning and moving toward the future. It’s a marvel that here in our township, and in other townships around the country, we’ve chosen to set aside areas like Ilsley where the history of our land and its native creatures can be preserved. The trees, wildflowers, birds and butterflies – all of it connects us firmly to our past –  and if we continue to be good stewards, will sustain and delight us for years to come as we move into the future.

DRAPER TWIN LAKE PARK: Fledglings, Hard-working Parents, Native Blooms, Butterflies and More

A kindly Dad taking his three young children fishing one morning at Draper Twin Lake Park.
Blog post and photos by Cam Mannino

Meeting the lovely family above at Draper Twin Lake Park one morning was a fitting beginning to my walk.  This dad was kept very busy baiting hooks and unhooking Blue Gills for his three young children who were excited to take their catch home and “eat ’em.” Well, the avian parents this week are as busy as that dad. Many fledglings are out of the nest but not quite “ready for prime time.” The youngsters’ flights are still a bit awkward, they haven’t quite grown into their beaks, and they object to being weaned from feedings by mom and dad. They crouch on branches, trying to look helpless by quivering their wings and begging “Feed Me!” with loud, high-pitched and incessant chirping. The conscientious adult birds are busy plucking berries, ferrying caterpillars and crunching seeds to fill young beaks. Meanwhile, more summer butterflies and other insects appear each day as native and non-native flowers line the trails and bloom in the wetlands. Summer, the busy season for nature, is well underway.

Industrious Parent Birds and Their Demanding Offspring!

A male cardinal gathering fruits to stuff into the beak of his fledgling

Twice as I entered the western path to the lake, I spotted a male Northern Cardinal (Cardinalis cardinalis) plucking little fruits from a bush and feeding them to his offspring. Juvenile cardinals have coloring similar to the female, except that their beaks are dark brown instead of red-orange like both adults. This hiding youngster couldn’t resist one peak at me over the tops of the greenery.

Juvenile cardinals have coloring similar to the female,  except her beak is red-orange and the youngsters’ beaks are black.

Further along the trail, a conscientious mother bird, the female Downy Woodpecker (Picoides pubescens), brought goodies to her youngster that was crouched on a branch in the classic quivering pose of begging fledglings. “Poor me; feed me; I’m starving.”

A juvenile Downy Woodpecker crouches and flutters in the classic begging style of baby birds looking to be fed.

Once mom took off, the youngster, its juvenile red cap on display, practiced a bit of upside-down branch hopping.

Juvenile Downy Woodpeckers have small red caps. Adult females have no red on the head and males end up with only a red dot at the back of the head.

A male Common Yellowthroat (Geothlypis trichas) sang an abbreviated version of his “Witchedy, witchedy” song repeatedly in a snag over the marsh. Farther up the path, I’d seen a young female hiding in a large bush, but it didn’t stop moving long enough for a good shot, I’m sorry to say. It has the slightly askew, downy look of a young bird. Thanks to Natural Areas Stewardship Manager Ben VanderWeide and expert birder Ruth Glass for identifying this little one for me! And to Bob Bonin for his fine photo of a fully fledged adult female so you can see how the little female will eventually look.

In another snag by the lake, a mother Red-bellied Woodpecker (Melanerpes carolinus) was busy feeding her nestling(s), traveling back and forth and stretching into the hole to feed whoever was inside. Those babies should be very safe in this nice deep hole in their lakeside dead tree!

Over in the eastern part of Draper Park, I was greeted by two fledgling Barn Swallows (Hirundo rustica) sitting on a wire by the parking lot. Adult Barn Swallows sport russet throats and loooong, deeply forked tails. These were obviously fledglings.

Two Barn Swallow fledglings sat quietly on a wire, occasionally testing their very long wings.

These youngsters were still slightly downy, shorter-tailed than adults, and only partially iridescent blue-black on the back. They sat remarkably still on the wire and periodically tried extending their wings. The fledglings below seemed to tip slightly back and forth as if trying to find its balance with those snazzy new wings. And the light color on the side of its bill is also typical of a juvenile Barn Swallow.

What appeared to be a well-behaved, quiet young Eastern Phoebe (Sayornis phoebe) – on the right below – traveled about on the edge of the north prairie as its parent (left) slipped down into the grass periodically to forage like grown-up flycatchers. From a distance in bright morning light, it was hard to see if the presumed youngster (right) had a slightly more yellow lower belly than the adult. The smaller bird looked a bit misproportioned, though, like a lot of fledglings do and also had a more “smudgy” juvenile breast as described by Cornell lab. So my conclusion is I was looking at an adult and its offspring.

An Unusual Sighting

Ben spotted a bird with a long sweeping tail in a snag near the prairie and quickly identified it. According to Cornell Lab, the Black-billed Cuckoo (Coccyzus erythropthalmus) is “common but secretive” and “heard far more often than seen.” Evidently, it eats lots of spiny caterpillars and has adapted to that spiky diet by shedding its stomach lining periodically to get rid of the spines. Yikes! I caught sight of the cuckoo flying with its very long tail trailing behind, but never got a shot. So here’s a beautiful photo from a gifted photographer, Jerry Oldenettel, on inaturalist.org.

Butterflies Big and Very Small

A female Black Swallowtail shows her distinguishing big band of blue spots as she sips from Hairy Vetch, a non-native vine.

A female Black Swallowtail butterfly (Papilio polyxenesprobed the funnel-shaped blossoms of Hairy Vetch (Vicia villosa), a non-native vining plant. The large blue spots at the bottom of the butterfly’s wing tell us she is a female and the two rows of  yellow spots indicate that she’s not the black morph of the Eastern Tiger Swallowtail (Papilio glaucus), which is very similar. According to Wikipedia, the orange spots on the underside of her wings protect her while she’s laying eggs, because they mimic the Pipevine/Blue Swallowtail (Battus philenor) which is toxic to birds. The Black Swallowtail is not, but birds will be wary.

The female Black Swallowtail’s orange spots on her hindwings mimic the Blue Swallowtail, which is toxic to many birds. Mimicry can provide protection.

Red Admirals (Vanessa atalanta) showed up on both sides of the park one morning. This butterfly migrates from the south rather than overwintering here. Look at those cool striped antennae with yellowish-white tips!

The Red Admiral butterfly migrates from the south each spring.

According to butterfliesandmoths.org, the Silver-spotted Skipper (Epargyreus clarus) rarely frequents white flowers and almost never yellow ones.  But the males do sit on tall flowers or grasses to attract females, so perhaps this handsome skipper was trying to snag a mate!

The Silver-spotted Skipper prefers more colorful flowers but may have been posing on this Daisy to attract a female.

Northern Pearly-Eye Butterfly that rested on the path one morning overwintered as a caterpillar. Like the early season butterflies (e.g. the Mourning Cloak), it feeds on sap from willows, poplars and birches or sometimes the fluids found in carrion or dung. Nature makes use of everything, doesn’t it?

The Northern Pearly-eye butterfly feeds on sap and other fluids, but not on flower nectar.

A pair of mating Little Wood Satyr (Megisto cymela) butterflies flew from the path to a nearby leaf still attached to one another as I approached.

Flowers Blooming at Draper Now that are New to Me

This month at Draper, Ben identified for me two beautiful native flowers I’d never seen before. Near the lake, we spotted the fuzzy blooms of another “Beard-tongued” plant, in the same genus as the Hairy Beard-tongue (Penstemon hirsutus) featured in our Photo of the Week two weeks ago. This one is called Foxglove Beard-tongue (Penstemon digitalis). Some blossoms have little lavender stripes inside to lead insects to the nectar, helping to spread their pollen.

The other native plant was a rose growing right next to the floating dock called the Swamp Rose (Rosa palustris). On one of the blooms, I spotted a tiny Katydid (family Tettigoniidae). Check out those long antennae!

 

A Slide Show of Flowers – Native and Non-Native – Currently Blooming at Draper Park

I always like to know the names of flowers whether native or not. It keeps me more aware of the detail in the landscape. So here are three kinds – native wildflowers, non-natives that are not always invasive, and an invasive plant that does harm to other plants by shading or crowding them out and multiplying aggressively.

Turtles vs. Creatures That Love Their Eggs

Often in early summer, I see Painted Turtles (Chrysemys picta) walking along the same trails I’m taking. They’re looking for soft, sandy soil where they can bury their eggs. Some places are definitely more hospitable for this purpose than others. This Painted Turtle came trundling along a path near Draper Lake, perhaps returning from an attempt to safely bury her eggs.

A Painted Turtle perhaps returning from a soft spot in the soil where she buried her eggs.

But out on the prairie on the eastern side of the park, evidence abounds that lots of animals love to find and eat turtle eggs. On one outing with the birding group, we spotted several turtle nest dug up with the leathery white egg shells laying outside.

Some animal has dug up a turtle nest and eaten the eggs leaving the rubbery shell.

Among the creatures that enjoy turtle eggs are raccoons, foxes, coyotes, skunks, and birds like herons, gulls and crows. As an (chicken) egg eater myself, I can’t complain. Luckily, Painted Turtles are our most abundant turtle species, so I assume nature is just taking its course as usual.

Dappled light on a trail on the western side of Draper Twin Lake Park.

It’s always iffy to anthropomorphize and assume that the behavior of other animals is similar to our own. We can’t, of course, know for sure what motivates a particular animal’s behavior. After all, we don’t understand our own motivations sometimes! But science is increasingly exploring the social and emotional lives of all sorts of creatures and discovering that many teach and learn in much the same way we humans do. And of course, animals have knowledge, skills, and memory that is superior to our own – for example chickadees remembering thousands of places they have stashed seeds or nuts. So when young fledglings beg to be fed or practice short flights in much the same way that little children pester us for food or learn to walk, it’s probably normal to feel an intuitive understanding of what might be going on. If we smile in recognition of our kinship with all creatures, maybe that will help us be more careful stewards of the natural world in which we’re embedded. And that has to be a good thing, right?

OUT AND ABOUT IN OAKLAND: Shifting Toward Winter at Cranberry Lake Park

What a difference a month makes!  I began a series of visits to Cranberry Lake Park on September 24 and ended on October 25.  I wanted to watch the park change as fall moved toward winter. It’s as if the color slowly leaves the flowers and grasses in the earth, flows up into the trees and then disappears into the black and white of winter. So this time I’m sharing a transition –  who and what is coming and going at this changeable time of year.

Late September:  Flowers Change to Fruit and Seeds

Mackerel sky CL
The meadow at Cranberry Lake in late September

In late September, the meadow was  still green, but splashed with the gold of Showy Goldenrod (Solidago speciosa). A sweeping curve of this beautiful native plant swept around the large thicket of shrubs in the center of the meadow. It was easy to imagine the path of last summer’s winds as it carried the seeds that created this graceful shape.

Showy Goldenrod 2 CL
Perhaps last summer’s winds carried the seeds that created this curving swath of Showy Goldenrod in the meadow.

And a few other flowers hung on in September.  Individual stems of Evening Primrose (Oenothera biennis) glowed gold among the greenery and a few hardy, flat-topped Yarrow stalks (Achillea millefolium) thrust their way above the browning Canada Goldenrod. Late-blooming Sweet Everlasting (Pseudognaphalium obtusifolium) – which some call Cudweed! – appeared as well, its tightly furled white buds just beginning to open in the cool autumn air. (Click on photos to enlarge; hover cursor for captions.)

Wild Grapes, also known as River Bank Grapes (Vitis riparia), hung in clusters on almost bare branches offering a  treat for migrating and resident birds – and a few of us humans as well! A few weeks later they had either fallen to the ground or been eaten right off the vine.

In September, the Staghorn Sumac (Rhus typhina) leaves changed from green to scarlet and the upright plumes of deep red fruits began to form.  One morning, a flock of Black-Capped Chickadees bounced among the branches, foraging either for fruits or the occasional bug. Perhaps they were the ones who stripped the fruit from some of the plumes. Sumac fruits are eaten by many game and songbirds, though normally they’re not a first choice this time of year.

Over the next few weeks, the Goldenrods began to brown and go to seed. Showy Goldenrod seems to start seeding from the top down, week by week. And eventually that golden curve of Showy Goldenrod had turned a seed-rich, but not very attractive, brown.

The golden swath of Showy Goldenrod turns to a brown, seed rich patch.

And despite not being a first choice fruit, the Staghorn Sumac’s seeds had either been eaten on the plant or fallen on the ground to be found by ground feeders.

Staghorn Sumac no seeds
Staghorn Sumacs’ plumes of seed disappeared in mid-October, either eaten by birds or dropped to the ground.

Talk about cool seeds! Looks at these elaborate seed pods of Dogbane/Indian Hemp (Apocynum cannabinum)! Dogbane is related to milkweeds, and like milkweeds the seeds with tufts of hair help the plant float on the breeze to new places. On the left is this red-stemmed, white-blossomed plant in June and on the center and right, the unbelievably long, angular seed pods this week.

Of course,  some seeds are actually a HUGE problem. In autumn, the invasive, tree-killing vine, Oriental/Asian Bittersweet (Celastrus orbiculatus), produces its seductively beautiful yellow and red fruits. This vine encircles the trunks of trees while climbing for the sun. In doing so, it can choke the life out of a tree. If it gets to the top, it can kill the tree by shading it out and/or by making it top heavy and more likely to fall in storms. Unfortunately, hungry birds eat the berries and spread Bittersweet readily through their droppings. PLEASE DON’T PICK THIS VINE OR MAKE WREATHS FROM IT , ETC. Contact the Parks Department if you want some strategies for getting rid of this beautiful “bad guy”!

By late October, the meadow at Cranberry Creek had turned November brown as plants continued to produce seeds.

I did, though, find a few shy Smooth Asters (Symphyotrichum laeve) tucked beneath overhanging foliage, braving the cold with the last of its lavender blossoms.

During  October: A Feast for Migrating Birds!

It’s hard for us to watch the palette of spring and summer fade – but birds? They love it! Warblers and other small visitors who spent their summer raising young in the cool northern reaches of Canada sailed into the park and found a feast! As did our year ’round resident birds.

One of my favorite partakers of fruits and seeds is the tiny Ruby-crowned Kinglet (Regulus calendula) who’s found its way here from around Hudson Bay in Canada – or even farther north. I seem to always miss seeing the ruby crown which the male shows when he’s excited. I guess the birds I’m seeing are either females or males that are just too calm!

Ruby-crowned Kinglet
Ruby-Crowned Kinglets arrived in October to feed and rest on their way south from northern Canada.

One afternoon at Cranberry Lake, the park was filled with White-throated Sparrows (Zonotrichia albicollis). They whisked in and out of shrubs while dashing down into the grass in search of seeds. This one paused just long enough for me to see its yellow lores, the spots at the corner of its eyes. It may have arrived from the UP or the tip of the mitten on its way to points south – not quite as arduous a trip as some migrators have.

White-throated Sparrow 3 CL
White-throated Sparrows have a shorter migration from northern Michigan to just southern Ohio.

This “first winter” White-crowned Sparrow (Zonotrichia leucophrys) was probably born this summer. It will take on adult coloring when it molts next spring into its bright black and white crown that now is brown and gray. This one was feeding avidly on goldenrod seed during its journey from northern Canada to somewhere south of Michigan.

One morning, far up the path in the shadow of trees, a small Hermit Thrush (Catharus guttatus) landed quickly, picked up a bug or fallen fruit from the grass, and took off.  No photo. But here’s one from a previous year with its chocolate brown back and breast smudges. Too bad the Hermit Thrush doesn’t court its mate here, because its song has 3 different phrases with a pause between each. You can hear two versions of it here.

The Hermit Thrush, with its chocolate brown back and smudges on its breast, picked up a few bugs or some  fruit on its way south.

Our birding group saw other migratory birds enjoying the rest and sustenance provided by Cranberry Lake Park, but through our binoculars. They were too far away or too restless for me to capture them with the camera. The little Nashville Warbler (Oreothlypis ruficapilla) is making its way from Canada’s far north  to Mexico or Central America. The Palm Warbler (Setophaga palmarum) stopped by on its journey from Canada to Florida or the Caribbean. And the Yellow-rumped Warbler (Setophaga coronata) has a comparatively short migration from northern Michigan or Canada to just south of Michigan. So as in all of our parks, Cranberry Lake offers much needed R&R for these small seasonal visitors.

During the bird walk, a Sharp-shinned Hawk (Accipiter striatus) swooped into the Hickory Lane on the west side of the park, perhaps chasing a songbird. It flew straight in front of us and quickly disappeared – we think without snagging the bird. Pretty exciting! Sharp-shinned Hawks are smaller and seen less often than the similar Cooper’s Hawk. They usually appear only during migration, so it’s probably headed south by now.  Here’s a link to a photo at Cornell Lab.

A summer resident, the Eastern Towhee (Pipilo erythrophthalmus) called “chewink!” from the edge of the woods one birdwalk morning. When Ben imitated his call,  the male Towhee darted into a nearby bush, intending, I assume,  to check out the competition. Here’s a photo of one from last spring.  (Let’s just say my photo luck was not with me on that bird walk!)

Towhee Draper Pond2
An Eastern Towhee chipped from the forest edge at the end of the bird walk.

So though we miss the flowers, they have done their work. They attracted the right pollinators which helped create the very seeds that feed tired and hungry migrating birds – as well as having provided bees with the makings for the honey that will feed them through the winter, too. As a compensation, color comes to us once more as the trees begin to turn.

Late October:  Winter Resident from the Far North Arrives – and Color Fills the Trees

Just this week, an American Tree Sparrow (Spizelloides arborea) may have flown into Cranberry Lake Park  from the edge of the Arctic tundra! This sparrow, with a spot in the middle of its gray chest and a two-tone bill, loves cold weather. During the summer, Tree Sparrows make elegant nests of ptarmigan feathers right on the ground in the Arctic in order to raise their young. Evidently for a Tree Sparrow, spending the winter in  Michigan  is like going to Florida! Below is the first one I’ve seen this year.

A flock of Eastern Bluebirds (Sialia sialis) did a lot to brighten up the browning of the meadow last week. Most Bluebirds migrate south, but a few actually stay with us all winter, either in family groups or small flocks, as long as there are seeds and berries available. I couldn’t resist taking more than one photo. Their splashes of azure in the field were really cheering on a gray fall day.

Color, of course, is the glory of a Michigan autumn. On September 24, the Hickory Lane still looked green and lush. By October 11, the colors had changed to gold and orange.   And on October 24,  a single glowing Shagbark Hickory (Carya ovata) at the south end of the lane was still shining in the sunlight after most of the other hickory trees began to turn brown.

The maple family contributes lavishly to the beauty of autumn.  On the path to the lake,  a striking leaf from a Red Maple (Acer rubrum) featured some colorful geometry. And nearby, the deeply lobed greenish-white underside of a pale yellow leaf from a Silver Maple (Acer saccharinum) created some contrast. At the lake’s edge, oak and maple leaves formed a scarf of fall color floating on the surface. 

The lake again was filled with migrating ducks and water birds – all much too far out for any kind of shot. Female Wood Ducks (Aix sponsa), Mallards (Anas platyrhynchos) and Mute Swans (Cygnus olor) were among the throng. Here are photos of those birds from  locations where I can get closer to them!

But there were also  Pied-Billed Grebes (Podilymbus podiceps),  and American Black Ducks (Anas rubripes)on Cranberry Lake.  Please click on these red Cornell Lab links if you’d like to see them up close. Let’s hope a viewing deck gets built on Cranberry Lake in the next few years so all of us can get a closer look in person at the water birds that flock to the lake in spring and fall to socialize and feed.

A Different Kind of Transition in the North of the Park

The greatly improved path entering the woods off of 32 Mile Road.

Finally, a wonderful transition is being finished on the trail at the north end of the park. The Parks and Recreation maintenance staff has spent long hours this summer improving the trail from 32 Mile Road into the park.  Instead of an oft-flooded, muddy track, they have laid down a solid surface with periodic drainage pipes running beneath it to keep the new trail from flooding.  You certainly can feel the difference underfoot!  And I imagine equestrians, as well as hikers, will appreciate the improvement. Thanks to Maintenance Foreman Doug Caruso and Maintenance Technician Jeff Johnson for a hard job that, when completed,  should be a great improvement for the park!

Autumn:  Harvest Time for All of Us!

chickadee-eating-seed
Black-capped Chickadee breaking open a seed.

So, just as we humans harvest crops before the snow falls, birds and animals harvest the wild “crops” of the fields – seeds and fruits. Some of them, like Black-Capped Chickadees (Poecile atricapillus), both eat and store them, tucking the seeds into bark where they will find them when snow blankets the meadow. Others, like the Palm Warbler, use them to fuel their flight to warmer climes. Winter residents, like the Tree Sparrow,  will probe the brown goldenrod  for seeds all winter – as well as flocking at your feeder. So when the color drains away, when the leaves are wet and brown underfoot, it may be a comfort to think of the bounty that surrounds us in those dry, drab plants. The brown and gray seeds nourish all kinds of creatures, and guarantee next summer’s bounty of plants. Those dry leaves underfoot dropped when they completed their work of sending sugars to the trees’ roots, ready to fuel next year’s growth. Seeds and falling leaves really are another reason to be thankful as November arrives. Maybe nature deserves a rest after a job well done!

Out and About in Oakland: Gallagher Creek Park – A Nature Oasis in a Busy Area

 

Viewing Platform GC
Viewing Platform at Gallagher Creek Park

I’ll admit that when I first visited Gallagher Creek Park, just east of Adams on Silverbell, I didn’t quite get it. It seemed like a rather ordinary, flat piece of land surrounded by a marsh. But luckily, I decided to look more closely and, as usual, the closer I look, the more nature shares with me. I’ve visited the park several times over the last month and each time I appreciate this little park more.

The stream flowing quietly through the grass beneath the viewing platform creates a cool, moist retreat for an abundance of birds and the special native plants that love wet feet. The Old Fields bloom with an astonishing variety of native wildflowers. Insects float and buzz between the blossoms. In short, this little park hosts an amazing variety of wildlife and plants with its combination of marsh, wet meadows and open fields (click here to see a map).  Let me show you just a sampling.

 

 

Gallagher Creek Itself:  A Haven for Birds and Wildflowers

The recently constructed viewing platform (thanks to Eagle Scout Jonathan Walling!) near Gallagher Creek allows visitors to watch the slow ripples of cool water flowing through the grass and trees. This gentle flow creates a soothing retreat that shelters creatures and plants of all kinds. According to three surveys by the Michigan Department of Natural Resources, Gallagher Creek is home to “one of the few remaining self-sustaining Brook Trout (Salvelinus fontinalis) populations in southern Michigan.”

After the last survey, though, they reported that the “gravel riffles and natural pools” had been silted by nearby construction, reducing the population from 300 Brook Trout per mile in 1998 to just 50 per mile in 2010.  (See Ben’s blog on this from 2015.) Native plants growing more abundantly at the edges of the park can act as a buffer and filter such sediment. Gallagher Creek runs northeast and enters Paint Creek at the Cider Mill in Goodison. If we want Brook Trout in our township, one way is to protect a cold water stream like Gallagher Creek.

Wetland Wildlife and Plants: A Riparian Corridor and a Marsh

Streams like Gallagher Creek create what’s called a “riparian corridor,” an area where the land meets a stream or river that not only filters and purifies water, but also provides habitat for a wide diversity of plants and wildlife. Antonio Xeira, our birder friend, spotted a  most impressive bird  near the creek. Here’s his photo of a Great Horned Owl (Bubo virginianus) who spends its days high up among the leaves of a Willow (probably black willow, Salix nigra) north of the stream. It’s not easy to see so I appreciate Antonio’s shot!  See that open eye?

A much smaller visitor among the willows is what I think was a Willow or Alder Flycatcher (Empidonax species) that perched in the shadows to preen. ( It could also be a Eastern Wood-Pewee (Contopus virens), but I’ll leave that for you to decide. They’re very similar.) It was a hot morning and this little bird was very busy dealing with the gnats or mites that can bother birds as much as they can bother us humans this time of year!

The shade near the stream also provided a stopover for a busy House Wren (Troglodytes aedon).

This hard-working adult was foraging for her young in a nearby thicket of native Gray Dogwood (Cornus foemina), which provides lots of cover and a food source for all kinds of birds at Gallagher Creek.

Gray Dogwood GC
Stands of native Gray Dogwood provide shade, protection and a food source in several thickets around Gallagher Creek.

One morning, I approached the thicket to see if I could see the young wren.  Immediately, the adult starting her scolding call, chipping incessantly at me, probably both to ward me off and to tell her fledgling to stay back in the trees. I did finally manage to get a shot of the youngster who appeared to still be growing into its beak!

Back in May, Antonio also noticed the burrow of a Crayfish (superfamilies Astacoidea and Parastacoidea),  a creature that loves clear, cold water streams. In case you haven’t seen a crayfish, I include a photo of one that I saw in Bear Creek.  If you enlarge the photo by clicking on it, you’ll see it’s a female carrying eggs under her tail! Crayfish are daylight creatures who retreat to burrows at night. I can’t say which species is in either photo. We do have one invasive crayfish in Michigan, the Rusty Crayfish (Orconectes rusticus), which fishermen used to use as bait and which have affected populations of our native crayfish.(Hover cursor for captions; click on photo to enlarge.)

Moisture-loving wildflowers in pink, purple, white and yellow bloom among the tall grasses and reeds  at the edge of the stream. Here are three native flowers that are easy to spot in the park – Blue Vervain (Verbena hastata), Canada Goldenrod (Solidago canadensis) and Joe Pye (Eutrochium maculatum).

The moist ground even a bit farther out from the stream suits many plants. Tall Sunflowers (Helianthus giganteus) and Water Hemlocks (Cicuta maculata), both natives,  prefer to sink their roots in moist earth.

Of course, dragonflies make their home wherever there is water. I saw a mating pair of Ruby Meadowhawks (Sympetrum rubicundulum) making a wheel of their bodies in the wet grass one morning.  The female is retrieving sperm from the male’s abdomen where he placed it earlier.  And to the right is what I think is another female Ruby Meadowhawk perching near the edge of the stream. Meadowhawk dragonflies (family Libellulidae)are plentiful this time of year and tough to identify,  but fascinating to watch as they hunt along the creek.

This thumbnail-sized Skipper butterfly (family Hesperiidae), I’m guessing a Delaware Skipper (Anatrytone logan), paused delicately on a moist leaf as I approached the stream.  Isn’t it elegant with its striped legs and antennae, large eyes and deep orange wings?

Gallagher Creek Park also shares an emergent marsh with its neighbors to the east. This thriving area is slowly being cleared of the dreaded invasive, Phragmites (Phragmites australis), which is much too prevalent in the area. It’s an on-going project of Dr. Ben and the Parks and Recreation Commision. How wonderful to see natives like sedges (Carex species) and Joe Pye flourishing as that terrible invasive plant diminishes!

Wildlife and Plants in the Old Fields

In the spring and early summer, our sharp-eyed birding friend, Antonio, found two nests on open ground at Gallagher Creek. I wonder if these eggs hatched since they seem so vulnerable. On the left is a Killdeer’s nest (Charadrius vociferus) from late April. The name, by the way, comes from their call, not from their effect on deer! And on the right is  a Spotted Sandpiper‘s nest (Actitis macularius) in early June.  Thanks, Antonio!

Now birds whisk in and out of the leafy trees at the perimeter of the Old Field next to the parking lot – many of them juveniles or adults working at feeding them. The “miaou” of a young Gray Catbird (Dumetella carolinensis) caught my attention at the edge of the field.  And later hearing a “cluck,” I look up to see an American Robin (Turdus migratorius), perhaps a molting female adult or a juvenile losing its spots, perched at the top of a snag.

Chipping Sparrow (Spizella passerina) and a male House Finch (Haemorhous mexicanus) hung out together in the bushes one hot morning.

American Goldfinches (Spinus tristis) provide the soundtrack for Gallagher Creek right now. These cheery little birds are one of the few who sing as they fly! With every downward swoop of their undulating flight comes a short burst of song. Here’s a male that settled for a few moments in that Willow, again – a popular place to pause for many of the birds here.

Goldfinch in willow GC
A male goldfinch settles in the willow trees, resting from his singing flight in the golfinch mating season.

Goldfinches mate in August because their favorite food source is available – thistle seed.  So they’re quite happy, I imagine,  that non-native Field Thistle (Cirsium arvense) established a large, plumed patch on the western end  of the loop path.

We appreciated being greeted by a relaxed Eastern Cottontail (Sylvilagus floridanus) when parking at Gallagher Creek one morning.  It seemed to be enjoying a bit of morning light after a long night of nibbling.

Rabbit GC

As Reg and I set out on the path, we were greeted by a sight I’d never seen before.  A Downy Woodpecker (Picoides pubescens) hung onto one of the huge non-native stalks of Common Mullein (Verbascum thapsus) in the Old Field. Downies eat both insects and seeds, so I guess it was just varying its diet

Closer to the water, this small bird fluffed its feathers as it settled in a bush. It looks a lot like the Willow Flycatcher but was a little bigger. So I’m guessing this is an Eastern Wood-Peewee (Contopus virens), but I can’t be sure!

Eastern Wood-PeeWee
I think from its size, this is an Eastern Wood-Pewee, but again, it could be a Flycatcher!

Among all the non-native wildflowers, like Queen Anne’s Lace and Spotted Knapweed in the Old Fields, many native wildflowers are increasingly making a home in the Old Fields here. In August of 2014,  Dr. Ben did what’s called a floristic survey of Gallagher Creek.  Of the 192 species he found on one day there, 131 were native!  Today they are more plentiful and healthy because Ben and his summer techs have eliminated many invasive shrubby plants and held repeated prescribed burns here. They plan to increase the native plant habitat in this park by planting native prairie species into the areas that were primarily non-native, invasive plants. The first phase of native plant installation will happen fall 2016, with a second round in 2017. Check out the sign on the west side of the driveway just as you enter the parking lot to learn more details.

In Bear Creek, Yarrow (Achillea millefolium) is an occasional plant, but  this summer, it grew in large swathes along the paths of the field near the parking lot at Gallagher Creek. Now, after the intense heat, it is turning brown and seeding for next spring’s crop.

Of course, native Common Milkweed (Asclepias syriaca) appears here and there, and is now producing its green, paisley-shaped pods. Along with more common Canada Goldenrod, another native called Grass-leaved Goldenrod (Euthamia graminifolia), flourishes as well. As I reminded readers last summer, Goldenrods do not cause “hay fever.” Their pollen is heavy and drops quickly to the ground. The sneeze-producing culprit that blooms at the same time is the wind-pollinated Ragweed (genus Ambrosia) which you can see if you click on the link.

Common Evening Primrose (Oenothera biennis) raises its graceful stems topped by yellow flowers among the grasses to the east of the park.  According to the Illinois Wildflower site (one of my faves), these flowers “remain open from evening to early morning, but will remain open longer on cloudy days. They have a mild lemony scent, and bloom from mid-summer to fall on mature plants. Long narrow seedpods develop, which split open from the top to release many tiny, irregular brown seeds. They are small enough to be dispersed by the wind, and can remain viable in the soil after 70 years.”  So if we keep caring for the land here, these night-blooming natives should be here for your grandchildren!

Common Evening Primrose blooms as the sun goes down until morning.

Out in the Old Fields, insects are busy in the late summer sun.  Carolina Locusts (Dissosteira carolina) spring into flight, their wings making a brown blur at your feet.

Viceroy butterfly (Limenitis archippus) explored the possibilities of a Queen’s Anne’s Lace bloom one hot morning. Viceroys are distinguished from Monarchs by the bars on their hindwings.

Clouded Sulphurs (Colias philodice) have a larger range of flight, feeding on taller plants like the Milkweeds and Coneflowers, but also on alfalfa or clover closer to the ground.

So, this modest little park is actually a rich oasis of native plants and wildlife along an important cold water stream  in the midst of the most developed area of our township.

Joe Pye GC
Joe Pye and Goldenrod complement each other near the creek where the reeds are growing in the background.

The Parks and Recreation Commission has plans to put a pavilion and perhaps even a play area in Gallagher Creek to make it even more inviting to its neighbors.  But right now, if you bring your binoculars and your curiosity to Gallagher Creek as the summer wanes, nature, as always, will reward you with lots of beauty to explore.

OUT AND ABOUT IN OAKLAND: Cranberry Lake Park – Birdsong, Flower-Studded Old Fields and Fancy Bugs

Ox-eye Daisies CL
Big, sunny patches of Ox-eye Daisies stare up from the Old Fields of Cranberry Lake Park

Strolling through the old farm fields of Cranberry Lake Park in summer is an auditory feast. The  canopied paths and wide open fields as well as the shady, moist wetlands celebrate summer with a full-throated chorus of birdsong – the quick sweet notes of the Yellow Warbler, the high-pitched trill of the American Redstart, the melodious song of the elusive Warbling Vireo. Ben’s birding group reports more than 50 different bird species on one spring visit, more than in any other park in the township. So you’d expect this week’s blog to be filled with bird photos, right?  Uh, not quite.

Version 2
Blog post and Photos by Cam Mannino

Oh, I do have bird photos to share but some will come from other times and places in the township because birding in Cranberry Lake right now is more by ear than by sight. Birds dive into tangled brush or tall grass or disappear among the whispering leaves overhead to make nests, feed young, intent at the moment on propagating their species. So they’re not all inclined to pose for photos.  Luckily, dragonflies, butterflies, grasshoppers – all sorts of insects –  do. And of course summer flowers are very obliging when a breeze pauses for a moment. So let’s set off together with eyes and ears alert to see what this historic farm has to offer.

Axford-Coffin House CL Western facade
The Axford-Coffin House, at one time a working farm and a country retreat, is now surrounded by a 213 acre park.

The lovely Cranberry Lake Farm Historic District on West Predmore Road is a township treasure and listed in the National Register of Historic Places. If you haven’t explored its beautiful grounds, I recommend you begin by taking a visual tour and learning about its history at this link. We, however, are off to explore the southern part of the 213 acre park that once was a working farm.

Out in the Sunny Old Fields

Old Fields Birdsong!

As we head off along the path from the parking lot that’s west of the historic home, we’re surrounded by knee-deep grasses and wildflowers. Tiny Yellow Warblers (Setophaga petechia) are whisking in and out of the large bushes or small trees nearby, still singing their quick “I’m a little sweet” songs as in Antonio Xeira’s recording here. This male with his rust-streaked breast actually paused long enough for a photo!

And another male Yellow Warbler nearby was busying bringing home lunch for his mate or maybe some nestlings in a distant bush.

Yellow Warbler male w food

On three different visits in the last 10 days or so, I heard or saw a male American Redstart singing in the same tree at a fork in the trail. I’m thinking he and his mate must have a nest nearby. For some reason, I’d never seen this bird before and he’s a beauty.  There’s a good closeup of him here at the Cornell Ornithology Lab. His song is thin, high and ends abruptly.  Cornell Lab says its sometimes described as sneeze-like!  Page down at this Cornell link to hear his song.

American Redstart
A male American Redstart sang in the same tree on three separate visits. Wish I could spot its nest!

In the same tree one morning, I saw a Tufted Titmouse (Baeolophus bicolor) swinging at the tip of a branch as it tried to harvest something from among the leaves. At this time of year, omnivore birds like the Titmouse are probably looking for protein for their mate or young, so perhaps he’d found a caterpillar?

Acrobatic titmouse

As I crossed the southern old field,  going north, two Common Yellowthroats (Geothlypis trichas) announced their territories, calling back and forth across this grassy meadow.

Yellowthroats have the distinction of being one of the first New World birds catalogued in 1766 by Carl Linnaeus, the famous biologist who created the Latin classification system for all life forms. My photo of the Yellowthroat is below but for a clearer photo of this masked bandit, look here on Cornell Lab’s website.

I rarely see Yellowthroats up close but you can hear their “Witchedy, witchedy” songs all over Cranberry Lake Park. Turn your volume up and you’ll hear the singing competition of two males going back and forth twice on my 25 second recording.

Out in the Old Fields:  Wildflowers,  Competing for Space

The old farm fields at Cranberry Lake exemplify the changes that happen over time when forage crops thrive in abandoned farm fields which are also surrounded by neighboring gardens filled with cultivated flowers.

Native plants are certainly here – native Canada Goldenrod will burnish the fields in the fall and other pre-development plants hold their own at Cranberry Lake, too. Here’s a gallery of a few of them. (Click to enlarge; hover cursor for captions)

The rosy stems of native Dogbane or Indian-Hemp (Apocynum cannabinum) will soon be topped with clusters of white flowers. This plant is toxic if eaten but I doubt you or your dog will be tempted.

Dogbane or Indian Hemp
Dogbane, whose stems will get rosier as it matures, is a lovely native plant that is toxic if ingested.

The meadows are full of non-native plants that, over the years,  have found their way into Michigan’s former farm fields. Many of them are good neighbors, existing side-by-side with native plants without crowding out the original inhabitants. I particularly like Orange Hawkweed (Hieracium aurantiacum), also called Devil’s Paintbrush (not to be confused with Indian Paintbrush). It can be problematic but isn’t at this point in Oakland Township parks. The Wildflowers of Michigan Field Guide explains that  the name came from a mistaken belief that hawks ate it to improve their eyesight!

Orange Hawkweed or Devil's Paintbrush
Orange Hawkweed or Devil’s Paintbrush – often confused with Indian Paintbrush.

Other non-natives pop up here and there in the old fields at Cranberry Lake.  Goat’s Beard blossoms open in the early morning and close about noon. And when its blooming season is over,  it makes a huge seed head, like a giant, beige dandelion, which it is doing right now. By the way, the insect on the blossom at left is a Hover Fly (family Syrphidae) which mimics bees or wasps for protection but has no stinger.

Other non-native plants that usually appear singly are White Campion (Silene latifolia) and Rough-Fruited Cinquefoil (Potentilla recta) which is easily confused with some of our native varieties (thanks to Ben for the ID help!).

Of course, invasive non-native plants have also moved into Cranberry Lake. Here’s a native House Wren (Troglodytes aedon), singing from within one of the worst  invasives, the Autumn Olive (Elaeagnus umbellata), a shrub which is native to Asia. These large bushes fix nitrogen in the soil, creating soil conditions unsuitable for native plants. Its berries are spread by birds and animals. It leafs out early and keeps its leaves late into the fall, shading out other plants. In short, it’s one problem shrub! But the Wren is a welcome summer resident  and his beautiful, burbling courting song  (recorded by Antonio Xeira) is much beloved even if it does emanate from an invasive bush.

Singing House Wren

Another serious  invasive shrub grows abundantly in Cranberry Lake, the Multiflora Rose (Rosa multiflora). This admittedly lovely plant loses its appeal when its strong thorns catch your skin, and this gangly shrub happens to be crowding out native plants all over Michigan. That hurts both our plant and wildlife communities by making native species less plentiful and less healthy because they are less diverse. Multiflora Rose was brought to the US from Japan by horticulturists after WWII as a fencing plant and spread quickly from gardens into natural or disturbed areas.  Like the Autumn Olive, it unfortunately can grow in sun or shade and has the same means of competing for space – lots of berries spread by wildlife and leaves early spring to late fall that shade out other plants.

Hairy Vetch (Vicia villosa)  is beautiful, like many invasives, but has a tendency  to spread. It was brought here as forage for animals. It isn’t as invasive as its relative Crown Vetch (Securigera varia), which forms dense colonies that exclude other plant species, but it does form smaller colonies and can be seen along the paths at various places in the park. Here a native Bumblebee (g. Bombus) probes the tube-like flowers with its long tongue.

And nearby, a Seven-Spotted Lady Bug (Coccinella septempunctata), a species introduced repeatedly from Europe to rid crops of aphids, looked for a meal on a fellow European, the Hairy Vetch again!  At least it wasn’t the Harlequin Ladybug/Asian Lady Beetle (Harmonia axyridis) that infested homes a few years ago. Unfortunately, our native ladybugs, the Nine-Spotted Ladybug, (Coccinella novemnotata) are now rare and scientists are not sure why that happened.

Out in the Old Fields: Fancy Bugs!

The sun-drenched Old Fields at Cranberry Lake seem to attract unusually interesting insects, including – wait for it – flies! Yes, I’m aware that flies aren’t as immediately appealing as butterflies or as impressive as dragonflies,  but some really are pretty cool.  Here’s a photo of a Soldier Fly (Odontomyia cincta) exploring the Dogbane. Can you see the black chevrons on his green back and his red head?  Pretty fancy, eh?

Or how about these mating Golden-backed Snipe Flies (Chrysopilus thoracicus)? The male is the smaller one with the much bigger eyes (“The better to find you with, my dear!”).

Of course, butterflies float above these fields as well. This weekend we saw our first Viceroy (Limenitis archippus) of the year. This one had a slightly injured forewing on one side, but was still happily fluttering about the field exploring flowers. Viceroys are often smaller than Monarch Butterflies and have a telltale bar on their hindwing that the Monarch doesn’t have.

What appeared to be a female Black Swallowtail (Papilio polyzenes asterius) hustled from blossom to blossom in the distance last Sunday, never alighting. So here’s an earlier photo from Bear Creek. I could, however, have seen the black form of the female Eastern Tiger Swallowtail which is very similar. 

A female Black Swallowtail fluttered above the old fields at Cranberry this weekend. Or it may have been the black form of a yellow Tiger Swallowtail, too.

And of course we saw the common but lovely Pearl Crescent (Phyciodes tharos), Cabbage (Pieris rapae)and Little Wood Satyr (Megisto cymela) butterflies as well.

One afternoon I saw a quick, snapping, short flight of what looked like a big moth with yellow-ish wings.  It turned out, after I saw it land, that it was a Carolina Locust in flight.  The “Bug Lady” at the University of Wisconsin-Milwaukee website says that “In The Handy Bug Answer Book, Dr. Gilbert Waldbauer refers to these unexpected wing patterns as ‘flash colors’ which, sometimes in concert with flight noises, attract/distract a predator. When the grasshopper lands and tucks in its flying wings, the pursuing predator suddenly can’t find anything that matches its search image.” That was certainly the case for me. It took me a minute to believe that this brown creature at my feet was the one I’d seen flying. Here’s a link where you can scroll down to a photo of one in flight.

Aaah, Out of the Sunlight: The Lake, Wetlands and Shade

Walking on shady paths and passing by wetlands, I naturally come across plants, insects, birds and other creatures that prefer that environment to sunny, open fields. Two Cedar Waxwings landed up in a leafy treetop on Sunday afternoon. My photo that day just doesn’t do justice to this lovely bird, so here’s a photo from another summer. The field marks of this elegant bird are its crest, its black mask, the yellow tip to its tail and a red dot on each wing that looks like red sealing-wax.   And their color does look like cedar, doesn’t it?

The field marks for a Cedar Waxwing are red wax-like dots on each wing, the black mask, the yellow tip of the tail and a soft crest.

Down near Cranberry Lake, three of the Wednesday birders recognized the melodious tune of the Warbling Vireo, here recorded by birder Antonio Xeira. What a lovely song flowing down from the treetops where it stays out of sight,  seeking out caterpillars. I love the contrast in these two song descriptions found at the Cornell Lab website. “The early twentieth century ornithologist William Dawson described the song this way: ‘Fresh as apples and as sweet as apple blossoms comes that dear, homely song from the willows.'” The highly variable song usually ends on a high note, leading the birder Pete Dunne to describe it as sounding “like a happy drunk making a conversational point at a party.” Here’s the closeup photo at Cornell Lab.

An incredible songster, the Gray Catbird (Dumetella carolinensis) makes a pastiche of other birds’ songs and strings them together. Walking past dense, low foliage, you can often heard him singing his avian version of “sampling,” as in this 45 second recording Antonio made on the Paint Creek Trail.

Creatures that Favor Moisture and Shade

Frogs generally love moist surroundings. In summer, though, the beautiful Northern Leopard Frog (Lithobates pipiens) often moves into grassy areas for its meals. One paused at the edge of the trail at Cranberry Lake Park, an emerald green frog with golden eyes and the spots that give it its name. Northern Leopard Frogs have very large mouths and though they usually eat worms, flies and crickets, they have also been known to swallow birds and garter snakes, according to Wikipedia!

Not hard to imagine how the Northern Leopard Frog got its name!

One warm afternoon, I came upon a Painted Turtle trundling along the path toward Cranberry Lake.

Painted Turtle male? CL
A Painted Turtle heading back to Cranberry Lake, perhaps after laying eggs in the sandy field?

I thought at first it was a male, because it had extra long nails which males use to stroke their mates. But I’m not sure, since it may have been a female coming back to the lake from laying eggs in sandy soil out in the fields. A few days later, my husband and I spotted a hole in the meadow edge where it appeared a raccoon might have dug up a batch of  turtle eggs to feed its young!

 Berries in the Shade

Cranberry Lake is of course important because it has a cranberry bog. At the moment, it’s not visible, but the Parks and Recreation Commission’s Master Plan includes construction of an observation deck at the lake in the next couple of years.

But other berries are forming along the shady path toward the pond.  The native Bristly Blackberry bushes are blooming under the trees.  In fact, their flowers are beginning to fade in the heat and the fruits, the blackberries, are forming.

And very near the lake, Ben pointed out Highbush Blueberries (Vaccinium corymbosum) forming in the shade. This is the plant that Native Americans enjoyed and that was domesticated in 1907 to create the blueberries we all enjoy in July.  I’m glad I got a photo, because when I went back a second time, some bird or mammal had already munched some of them.  They don’t wait until their ripe the way we do!  Drat…

Along the Hickory Lane on the west side of the park, I saw fruits forming on False Solomon’s Seal, a native plant that spreads by rhizomes (underground stems) under the trees.

Insects that Have It “Made in the Shade”

Dragonflies patrol along the shady paths as well as the open meadows.  I saw one last week that I hadn’t seen for a long time, a female Eastern Pondhawk (Erythemis simplicicollis). She’s emerald green all over with brown/black chevrons on her tail. According to the “Bug Lady” at the University of Wisconsin Milwaukee,  the male gradually changes from green to blue, starting at the tip of its tail and moving up as it matures! These dragonflies stick close to animals, like us, because we stir up a cloud of biting insects they love to eat. Thanks, Pondhawks! Enjoy an all-you-can-eat feast!

Eastern Pondhawk3 CL
A female Eastern Pondhawk dragonfly is emerald green, unlike the male who changes from green to blue as it matures.

Another dragonfly who seems to frequent moist areas almost exclusively is the Dot-tailed Whiteface (Leucorrhinia intacta). The male looks like he’s wearing a Mickey Mouse mask with his white face and eyes. What I think was his mate landed nearby. I couldn’t see her white face but all of her tail and wing markings and her location near the male would seem to indicate she’s the female.

Damselflies also patrol the paths as you near Cranberry Lake itself. Emerald green seems to be a popular color for creatures who want to disappear from predators in the shade. Here’s one called, appropriately enough, the Emerald Spreadwing Damselfly (Lestes sponsa).  

Below the huge Shagbark Hickories (Carya ovata) on the lane at the western edge of the park, a Virginian Ctenucha Moth (Ctenucha virginica) sailed past and settled on a leaf. I was quite excited to see this moth (which caused a slight blur in the photo), since Ben had helped me identify its spiky caterpillar earlier in the spring. It’s quite common and likes goldenrod nectar. This one might have hatched a bit early in  the heat, since the goldenrods won’t bloom for another month. This elegantly shaped moth with an orange head flashes its metallic blue body when it flies.

A Park for All Seasons

Improvements continue  at Cranberry Lake Park.  The northern most part of the central trail that connects with trails in Addison Oaks county park is being renovated this year (and possibly next) to make it less damp so that hikers, bikers and horseback riders will have an easier time accessing the park. That northern section is full of wetlands, those precious resources that clean our groundwater, store flood waters, feed our wildlife and give shelter to exhausted migrating birds – but they make for wet trails in the spring.

But most of the park is open for your enjoyment year ’round  with migrating warblers in the spring, breeding birds in the summer (and summer concerts on the farmhouse porch), a bright orange glow in late summer and fall as Canada Goldenrod bloom and Monarch butterflies fill the fields traveling south. In winter, its gently rolling meadows might be a place to try out your cross-country skis. And then there’s all that history near the Flumerfelt Barn and historic home. So branch out. Try a new park this summer and see what you and your children can find  to love at Cranberry Lake Park.

Planting Prairies: Oakland Township Restoring Its Natural Heritage

Before European settlement, our special area of Michigan was actually an Oak Savannah with large expanses of tall waving grasses,

Big Blue Stem in the wind

widely scattered, spreading oaks

and other native trees, shrubs and prairie wildflowers.  During the spring and summer, ground-nesting birds like the Northern Bobwhite Quail  (Colinus virginianus) settled among tall grass stems, producing young.  Bobolinks (Dolichonyx oryzivorus) sang their burbling song while swaying on grass stems.  The Eastern Meadowlarks (Sturnella magna) whistled their slow song from perches in low shrubs.  Later, in the 1800’s, non-native game birds like Ring-necked Pheasants (Phasianus colchicus) were introduced and took advantage of the tall grass for cover.

On November 14 and 15, Oakland Township’s Stewardship Manager, Dr. Ben VanderWeide, took a huge step forward in prairie restoration on  20 acres of Draper Twin Lake Park and another 18 acres in Charles Ilsley  Park.  The hope is that residents will  be able to experience the land as it may have looked before and that native residents – birds, animals, grasses, wildflowers, shrubs and trees of the prairie – can return, adding more rich diversity to the plants and wildlife of Oakland Township.

The process began in the summer of 2014 as crews working with Dr. Ben began removing the non-native and invasive species that had taken over the land after farming had ceased.  This meant long hours of cutting woody invasive trees and shrubs like Autumn Olive, Multiflora Rose and Glossy Buckthorn which had quickly colonized the open land, and then treating the stumps to prevent re-growth.  The process continued this summer until one beautifully rolling 20 acre field was finally prepared for planting in Draper Twin Lake Park.

About to be prairie Draper Lake
20 acres of soon-to-be prairie at Draper Twin Lake Park

Two other rolling fields of 5 and 13 acres at Charles Ilsley Park were also cleared and prepared.(Click on double photos for larger view.  Rest cursor on photos for captions.) Two more 15 acre fields are being prepared for planting in 2016 and 2017.

Dr. Ben sought out a U.S. Fish and Wildlife grant to purchase wild seed for these areas and then carefully selected a list of plants suitable for our specific sites. Township residents will need to be patient, since prairie flowers spend their first two to three years putting down deep roots. These deep roots help prairie plants survive drought conditions or fire to which they became adapted over thousands of years of fluctuations in climate and periodic fire.  In fact, carefully controlled prescribed burns will be used periodically on these prairies in the future because regular burning helps native plants thrive and thwarts non- natives who are not adapted to it. Some native plants even require fire in order to bloom!

A few flowers will begin to appear next spring, but the prairies should really start blooming vigorously by the spring and summer of 2018.  Here are just a few of the prairie grasses and wildflowers that will be gracing our prairies then. (Click on photos to enlarge them and hover your cursor over the photo for plant names.)

Along with these more familiar native plants, Dr. Ben also included grasses and flowers that used to bloom here but that we see less often now. Click on these links to see Foxglove Beardtongue (Penstemon digitalis), Wild Lupine (Lupinus perennis), and Sky-blue Asters (Symphyotrichum oolentangiense).  And that’s only a sample of the 36 species of plants Dr. Ben ordered!

With those plants up and growing, our parks can attract more butterflies and native prairie birds like those mentioned above or maybe other special species, such as the  Northern Harrier (Circus cyaneus), or Henslow’s Sparrow.

So that November weekend, Jerry Stewart from Native Connections brought equipment designed for planting native seed. Jerry first carefully calibrated the seed drill for the  seed type, planting rate, and depth.  He then loaded seed in the hoppers and was ready to go.

Four of our former OT stewardship technicians, who had worked hard to clear land for this project, joined Dr. Ben and Parks Commissioner Colleen Barkham (not pictured) to see the moment when the seed finally went into the ground. The former technicians are now finishing up school or pursuing careers in various environmental fields.

Now the native seed is in and next spring,  sturdy native wildflowers and grasses will begin sinking their roots deep into the soil, a survival strategy that will take them 2 or 3 summers.  And then in year three or four, we will be able to watch prairies in full bloom again in Oakland Township.  As time passes we hope the wildlife return –  butterflies floating above swaying grass and native wildflowers, while the Bobolinks sing and the “Bob-White!” whistle returns to grace the summer months.  Dr. Ben shared some photos taken on the Flint Hills prairie in Kansas (where he completed his doctorate)  in order to help us dream until then.

THIS WEEK AT BEAR CREEK: Visit the Bear Creek Nursery, Babies Galore! and One Strange Creature…

There’s just something endearing about almost any baby creature and now is the time to go “awww” in Bear Creek (or in your backyard for that matter!)

Blog post and photos  by Cam Mannino

Adult birds stuff the mouths of hungry fledglings, tiny frogs (and I do mean tiny!) spring across the mud and  through the grass at the edges of vernal pools, and young woodchucks and bunnies sally forth to forage in the grass.  The park is full of babies!

(Note:  Though I can venture a short way into the park now, my mobility’s still pretty limited by the accident.  So though all these baby creatures are at Bear Creek now, some of the photos were taken near my home.)

Fledglings and Others in the Nursery

On the Wednesday Bird Walk at Bear Creek this morning, Ben and other birders spotted fledglings all over the park. The fledglings are there for us to see and hear if we take the time to listen and watch.  Sometimes you can hear their squabbling when adults bring food to the nest.  At other times, you can hear the insistent peeping that accompanies their begging posture – tail up, wings down, fast flutter of the wings.  Here’s an example from home of a female House Finch (Haemorhous mexicanus) with her begging fledgling:

adult and fledgling house finch
A fledgling House Finch assumes the classic begging pose.

Adult birds model feeding behavior for their young – pulling worms, cracking seeds, swallowing bugs in mid-air – but it takes time for fledglings to choose independence and stop begging to be fed directly by their parents.  (Sounds like some human adolescents I’ve known…) Here’s an adult Tufted Titmouse (Baeolophus bicolor) on the right approaching its young with a seed…

adult and fledgling titmouse
An adult Tufted Titmouse brings a seed to a fledgling with an empty hull in its beak. Like babies, they stick crazy things in their mouths.

And then, in a rather awkward move, the adult stuffs its big seed into the fledgling’s beak.

titmouse feeding fledgling
The adult titmouse awkwardly pushes a seed into its fledgling’s beak.

The Tufted Titmouse is a relative of the Black-capped Chickadee and like them, cracks seeds open between its feet and hides some to eat later.  Tufted Titmice make their nests in tree cavities and line them with animal hair, sometimes plucked from passing animals and sometimes found in old squirrel or raccoon nests.  One of the reasons it’s good to leave dead trees in a forest is that the Titmouse can’t excavate a hole itself,  so it needs woodpeckers’ holes from the previous season.

Fledglings are trying out a lot of adult behavior and exhibit a lot of curiosity, just like all youngsters.  Here’s a female House Finch fledgling shot this week who knows she should look around carefully before feeding, but maybe is exaggerating the stance just a bit!

A curious fledgling House Finch trying to be cautious before feeding and maybe overdoing it.

Besides being very curious, juveniles often have different plumage from adults and their wing feathers are usually smaller.  See the short wings on this  female fledgling Rose-Breasted Grosbeak (Pheucticus ludovicianus)?

grosbeak fledgling
Fledglings, like this female Rose-Breasted Grosbeak, still have to develop the long wing feathers they’ll need as adults.

And this thin, young Northern Flicker (Colaptes auratus) has the mustache of a male, but it hasn’t gone through the fall molt yet.  Males will keep that mustache.  Females will lose theirs.

fledgling flicker
This young Northern Flicker needs to go through the fall molt before we’ll know whether it keeps the male mustache or loses it because it’s a female.

Of course, the mammal babies explore Bear Creek at this time of year, too.  Here are two young Woodchucks (Marmota monax) learning to forage near our woods on July 1 last year.  Also called Groundhogs, these lowland marmots,  the largest members of the squirrel family (Sciuridae) in our region, are generally herbivorous (vegetarian) and are amazing diggers (as many of us know too well around home!).  They make large burrows, equipped with a spy hole, a nest/sleeping area, a toilet chamber and up to 45 feet of tunnels!

baby groundhogs
Young groundhogs explore the grass near the woods at my home on July 1 – but you’ll see them all over Bear Creek too!

And, of course, there are always little Cottontail Rabbits (Sylvilagus floridanus). I like this description from the Michigan DNR of the mating ritual of rabbits, something I’ve never witnessed: “This usually occurs after dark. The buck chases the doe until she eventually turns and faces him. She then spars at him with her forepaws. They crouch, facing each other, until one of the pair leaps about 2 feet in the air. This behavior is repeated by both animals before mating.”  Pretty athletic!  Rabbits have 3 or 4 litters a year on average so there are always plenty of bunnies. Here’s one sucking in a grass stem bit by bit.

And then, of course, it had to clean up a bit after eating.

On Tuesday of this week, the grasses around the vernal pools in the north end of the park were alive with baby Wood Frogs (Lithobates sylvaticus) of various sizes.  This tiny one was struggling to get out of a tire rut some thoughtless person had made in the pedestrian entrance on Gunn.  He’s only about 3/4 of an inch long!  I don’t think I’ve ever seen a frog this small before!

About that Strange Creature…

By the way, at one of the vernal pools in the north end of the park under some wood, we found a Blue-Spotted Salamander (Ambystoma laterale).  It was about to rain and very dark in the woods,  so I apologize that the photo is not as sharp as I would like but it’s such an interesting creature, I had to share it with you anyway. 

Blue spotted salamander
The Blue-spotted Salamader hides under logs or bark in moist areas and can regenerate its tail – which detaches if attacked!

Salamanders are strange creatures.  According to the Michigan Department of Natural Resources,  “When danger is sensed, the blue-spotted salamander’s tail lashes back and forth and produces a noxious secretion from two glands at the base of its tail. Even if the predator gets by this defense, it may only end up with a small morsel. When grabbed,  the salamander’s tail will detach. While the predator is detained by the writhing tail,  the salamander zips off to safety. In time a new tail will grow to replace the lost one.”  So, uh, don’t grab one.  They’re pretty darn slippery (one is tempted to say “slimy”) anyway!

Native Plants in Bloom!

So let’s move out into the meadows and marshes and see what’s blooming!

A fun native wildflower is blooming in its own inimitable way in the northern area of the marsh. Common Bur-Reed (Sparganium eurycarpum), like  many of our native plants, can survive fire in wetlands because it spreads underground through rhizomes (root-like underground stems).  Muskrats munch on the rhizomes and water birds eat the seeds which of course helps keeps its growth under control.

bur-reed
Muskrats eat the underground stems of Common Bur-Reed and birds eat its seeds – a native contributor to marsh life.

Last year, at the edge of the woods near the intersection of the path behind the pond and the eastern arm of the Northern Loop, Whorled Loosestrife (Lysimachia quadrifolia) made its appearance.  Like many native plants in our area, it favors sandy soil and oak/hickory forests, which is exactly what Bear Creek offers.  I hadn’t noticed it until last year,  but perhaps you did?

whorled loosestrife
Whorled loosestrife (unlike Purple Loosestrife, an invasive) is a native plant that likes the sandy soil and oak/hickory environment of Bear Creek.

Probably like me, you’ve passed by another native plant for years without paying much attention.  Yarrow (Achillea millefolium)  pops up all over Bear Creek – and lots of other places around the world, actually – and doesn’t look that glamorous – until you look closely at its myriad of little white flowers. Our Yarrow may have hybridized at some point in its past.  The more light pink those little flowers are the closer it is to the native variety. I like it in any case.

Yarrow is a modest native that looks like a wedding bouquet when you get close to its tiny disc flowers.

 Coming Attractions:

One of Ben’s and my favorite native wildflowers is budding all over Bear Creek and blooming in the southern native bed.  It’s Butterfly Milkweed (Asclepias tuberosa) and just watch!  It will live up to its name once the warmer weather comes.  Butterflies and bees love it even more than we do!

DSCF5509
Butterfly Milkweed will justify its name when butterflies (and bees) flock to it in July.

So put on your bug juice (all this rain has unfortunately made for a bumper crop of mosquitoes) or come when it’s windy and sunny and watch for the young ‘uns.  They grow up fast, just like our children.
