Charles Ilsley Park: A-Flutter with Wings of All Sizes

Text and Photos
by Cam Mannino

At the end of May, spring migration wound down and the breeding season heated up. The migrators and the year-round avian residents of our parks busily set about nesting and tending their newly hatched young. Their bright wings flashed color into the pale spring sunlight, much to the delight of hikers like me and my new photographer friend, Paul Birtwhistle.

Meanwhile, in the meadows, the tiny wings of small butterflies and moths fluttered at my feet and in the tall grass at the trail edge. The wings of ant-sized solitary bees beat almost invisibly as they probed blossoms for nectar. It seemed the whole park vibrated with wings!

So come hang out with Paul and I as we wandered the meadows, wood edges and forested wetlands of Charles Ilsley Park, enjoying the company of winged creatures.

Summer’s Yearly Visitors Offer Song, Color – and New Life! – to Park Visitors

Our Natural Areas Stewardship Manager, Dr. Ben Vanderweide (far right) joins a birding group from Seven Ponds Nature Center in watching a migrating Blue-headed Vireo at Charles Ilsley Nature Park.

In May and early June, birdsong filters down through the fresh green leaves as birds arrive from wintering in warmer climes to enjoy the bounteous feast of insects provided by a Michigan spring. Migrators journeying farther north may pause to forage and rest like the Blue-Headed Vireo (Vireo solitarius) spotted high in the treetops by the birders pictured above.

But many birds settle here for the summer, making the most of the abundant food and shelter our parks provide. Some sweep insects out of the air. Others pluck them off bark or probe for them in the ground. While Paul and I didn’t manage a joint trek through Charles Ilsley Park, we both saw a similar rainbow of birds singing to declare their territory or carrying off caterpillars to feed mates on the nest or newly hatched nestlings.

Birds In or Around the Tall Grass of the Prairies

My visits to Charles Ilsley Park usually begin by walking along the entrance path while monitoring some of the township’s nest boxes. Two other trained volunteers and I keep records of the first egg laid, the hatch and fledge dates and any issues that develop around the nest, like predators (House Sparrows, for example). We submit the data to Cornell University’s NestWatch site as part of a citizen science project.

This year three different species have settled in the boxes that I monitor. Eastern Bluebird babies (Sialia sialis) have broken naked from their shells, begged for food and ultimately found their way into the big wide world. [Click on photos to enlarge.]

Paul and I were both lucky enough to see the adults working to make this happen. It looks like the female of both of these pairs was delivering food for her young while the male stood watch.

A House Wren (Troglodytes aedon) in one of my boxes laid her eggs in a very tidy circle. Wrens fill their boxes almost to the top with twigs, topping them off with just enough grass and feathers to cushion their young. Somehow, the female makes her way into that tight spot to incubate her tiny eggs. I imagine the crowded box discourages predators from entering. By the way, this is an extreme closeup; the wren’s eggs are just a bit larger than a dime!

House Wren eggs laid in a neat circle within a nestbox crammed with twigs and topped with grass and feathers.

Tree Swallows (Tachycineta bicolor) take up residence in our boxes as well. After building a nest of dry grass, they collect feathers, almost always white ones, to create a soft covering for the eggs. It’s amazing how many white feathers they find; I’ve read, though, that they sometimes snitch them from other Tree Swallows! Paul got a lovely photo of a male perched like a pasha on another dry Evening Primrose stalk. These striking birds glide above the meadow grass, beaks agape, collecting insects as small as gnats and as big as dragonflies.

At the end of the entrance trail, beyond the nest boxes, I’m greeted by restored prairies rolling off in all directions. In May, Ben brought in a contractor to do a major prescribed burn in Charles Ilsley Park. The low flames moved across the east and north prairies, even taking in the forests around them as part of the planned burn.

The Eastern Prairie at Charles Ilsley Park four days after the prescribed burn.

It was a dramatic sight in the first few weeks to see the blackened land begin to flourish again. The burn replenishes the soil with nutrients held in the dry plants, and the blackened surface and warmth of the fire provides a longer growing season for many native plants. Many non-native plants can be thwarted by periodic fire, unlike our fire-adapted native species.

At the entrance to the eastern prairie, an up-and-down two note call issued from the small copse of trees. Wow! I was lucky enough to see a Red-eyed Vireo (Vireo olivaceus) at close range. Usually I only hear vireos because they tend to stay high in the crowns of trees. What a delight to watch this one hop about in small trees long enough to get a quick photo!

One of my favorite migrators spends the winter among the colorful birds of South American forests. Dressed elegantly in black and white with its upright posture and white tail band, the Eastern Kingbird paused for Paul while surveying its territory. Kingbirds can be aggressive toward birds near their nests, even large ones flying high overhead.

An assortment of summer sparrows make the most of our restored prairies. Once I began to pay attention to their varied songs and patterns in brown, black and white, they added interesting detail to my hikes. Ben VanderWeide, Oakland Township’s Natural Areas Stewardship Manager, helpfully compares the song of the Field Sparrow (Spizella pusilla) to the sound of a bouncing ping-pong ball. It starts with slow, sharp bursts that rapidly accelerate into a series of quick, rat-a-tat-tat notes. The melodies of the Song Sparrow (Melospiza melodia) can vary but are usually characterized by a couple of quick notes followed by a short melody that ends in either a trill or a buzz. For me, the songs of these two birds are the soundtracks of summer in all of our parks.

Birds in the Treetops and Forested Wetlands of Ilsley’s Western Trails
The western woods at Charles Ilsley Park features vernal pools like this and a long, mysterious marsh.

A large wetland runs along the northern edge of the park’s western section. It lies beyond the moist forest that edges the trail and may be missed by some hikers. Luckily, Paul willingly went off trail to get closer to the green surface of the long marsh which is covered with plants that are often mistaken for algae. Common Duckweed (Lemna minor) in my photo below is the small, leaved plant that floats on the water and Water Meal (Wolffia columbiana) is the tiny plant between the Duckweed which can multiply to form a dense mat on the water surface, as it does right now at Ilsley’s western marsh.

The larger leaves are Duckweed and the smaller are Water Meal which has created a thick green mat on the surface of the long western marsh at Charles Ilsley Park.

Evidently, a male Wood Duck (Aix sponsa) found it quite a suitable surface for exploring! I wonder if its nest is high in the trees nearby? Wood Ducks are perching ducks that use the hooks on their webbed feet to negotiate tree bark. According to the Cornell All About Birds website, their ducklings can fall fifty feet from their nest into the greenery below without injury.

Two adult Canada Geese (Branta canadensis) and their four goslings demonstrated the appeal of a nice lunch of Water Meal and Duckweed.

Exploring in the west of the park, Paul spotted the impressive Great Crested Flycatcher (Myiarchus crinitus). Inspired by his success, I spotted it later too, but it was rapidly hawking insects out of a high tree at the time. According to Cornell’s All About Birds website, this bird spends almost all of its time seeking insects high in the canopy or scooping them out of the air. Sometimes, Cornell says, it may even “crash into foliage in pursuit of leaf-crawling prey”! I want to learn their rising two note call so I can see their chocolate wings and lemon breasts more often!

The Great Crested Flycatcher’s yellow breast should make it easier to spot from below as it hunts high in the tree canopy. I’m still learning to spot it, though!

On the May bird walk at Charles Ilsley Park, several brightly colored migrators decorated the treetops along the western trail. All of the colorful characters in the slideshow below can breed in our area. So during late June and early July, keep yours eyes open for the nests or fledglings of this avian rainbow when hiking in shrubby areas or at the forest edge!

Pollinators’ Danced at My Feet, Fluttering Their Small Wings Along the Grassy Trails

Since Paul kindly agreed to look upward and outward for birds, I felt free to gaze down into the grass along the trails, looking for the tiny butterflies and moths that often appear before larger insects. On the bird walk, a member spotted the small Eight-Spotted Forester Moth (Alypia octomaculata) that sports puffs of orange hair on its front and middle legs. As the Missouri Department of Conservation points out, it can easily be mistaken for a butterfly: it eats nectar, flies in the daylight and its antennae thicken at the end somewhat like butterfly attennae. This one appeared in its favorite habitat, the place where the field meets the forest. The adult moth feeds in the sunshine, then lays its eggs in the shady woods on grapevines or Virginia Creeper (Parthenocissus quinquefolia), the host plants its caterpillar loves to eat.

The Eight-Spotted Forester Moth lays its eggs and pupates in the forest, but the adults feed in the sunshine at the forest edge.

The birding group also watched a tattered Mourning Cloak butterfly (Nymphalis antiopa) feed on invasive Autumn Olive (Elaeagnus umbellata.) It looks as though overwintering in a log or under tree bark took its toll on this one! Nearby, we spotted a strangely still Giant Swallowtail (Papilio cresphontes). The Butterflies of Michigan Field Guide by Jaret C. Daniels informed me that their host plant is Common Prickly-Ash (Zanthoxylum americanum), a small, thorny tree on which the female can detect a citrus scent with her antennae. I wonder if this Giant Swallowtail was drying its wings after having recently emerged from its chrysalis on a nearby tree.

A few days after seeing the Eight-spotted Forester Moth, I found a very similar small moth at my feet on the trail. It too was tiny and black with white spots, but its orange patches were on the surface of its forewings. With help from the passionate moth lovers at the “Moths of Eastern North America” Facebook page, I learned its name. This thumb-sized, diurnal insect, called the White-spotted Sable Moth (Anania funebris), is referred to as “holarctic,” because it inhabits the majority of continents on the northern half of the planet! This particular Sable Moth seemed to be exclusively feeding off the clover blossoms on the trail, one after another. Though this moth must be quite abundant, I’d never noticed one before.

A White-spotted Sable Moth seemed to be exclusively interested in clover blossoms on the low grass of the trail.

During several different visits, I noticed other small butterflies and moths that kept me company along the trails. The two tiny “tails” at the edge of the hindwings give the Eastern Tailed Blue its name. The Pearl Crescent is named for a small white shape on the underside of its hindwing. The caterpillar of the Peck’s Skipper chews on turf grasses but seems harmless among the wild grasses of our parks.

On my last visit, a dramatic Red-spotted Purple butterfly (Limentitis arthemis astyanax) glided by as I entered the park. I sometimes still mistake them for Spicebush Swallowtails (Papilio troilus troilus) because of the blue, iridescent blush on the top (dorsal) side of their hindwings and the orange spots on the ventral (lower) side of their hindwings. But the Purples have no “tails” and the orange spots beneath form a single line on the hindwings instead of the double line of the Spicebush Swallowtails, as you can see below.

The Beautiful and the Less So: Justifying (Maybe?) My Fascination with Less Likable Creatures

Dr. Doug Parsons, director of Michigan State University’s Bug House, helped me identify a couple of tiny insects that intrigued me. I’d watched what I thought were tiny wasps on almost every dandelion on the trail through the park’s Central Prairie. Dr. Parsons explained that these were not wasps, but Cuckoo Bees (genus Nomada).

Dr. Parsons wrote that this solitary bee “sneaks into the ground nest of the host bee,” most often a Mining Bee (g. Andrena), and “lays her eggs in the cells that the host bee has stocked with pollen for her own larva.” Since Mining Bees never return to the nest after stocking them, the Cuckoo bee’s egg hatches into a larva undisturbed, kills the host’s egg or larva and feeds on the stored pollen. The official term for a creature which does this is a “nest kryptoparasite,” a suitably creepy word for such behavior! Birds in the Cuckoo family do the same, laying their eggs in the nests of other birds – hence the name Cuckoo Bee. This native bee resembles a wasp in part because it has very little hair on its body. Dr. Parsons explained that bees are often fuzzy in order to collect sticky pollen. Since the Mining Bee collects the pollen that feeds the Cuckoo Bee’s young, this sneaky interloper doesn’t require the other bee’s hairier surface. Ah, another fine example of evolution working its magic.

The Cuckcoo Bee lays its eggs in the pollen-stocked nest of other solitary bees, eliminating the need for pollen-collecting hairs on its body.

Last week, I also observed a nondescript, brownish moth fly onto a grass stem, fold itself up and almost disappear. It was quite a challenge to locate it in my camera’s viewfinder! Dr. Parsons confirmed that this little moth is the Eastern Grass Veneer (Crambus laqueatellus). Evidently, some folks refer to these members of Crambidae family as “snout moths” because their long mouth structures resemble pointed noses. Dr. Parsons told me they can be “serious pests in lawns and golf courses” because their caterpillars eat turf grass roots. He isn’t sure, though, that they cause problems in our parks where their larvae may consume a variety of grasses. For me, its disappearing act, pointed “snout” and racing-striped wings were just odd enough to make it a fascinating find.

The Grass Veneer Moth is perching vertically on a small grass blade, its wings folded and its long “snout,” (which is really part of its mouth) pointing straight up. And look at that weird white eye! A delightfully odd little moth with its brown racing stripe, don’t you agree? OK, maybe not…

I’m sure that I puzzle some of you by including unglamorous, fiercely predatory or even destructive creatures in these nature blogs. Sometimes it puzzles me too that I want to explore them. But I guess for me, all of these creatures – from the Cuckoo Bee to the glorious Great Crested Flycatcher – play an essential role in the great drama of nature. By learning a name for these fellow players and the roles they perform on our shared stage, the whole spectacle and my role in it become clearer for me, more coherent – which in these chaotic times is a pretty good feeling! It’s my role – our role perhaps – to honor and respect nature in all its complexity during an era in which too many dishonor the natural world, ignore it or take it for granted. I know you, like me, care enough to watch, learn and share what you learn with others when you can. And that encourages me. Thanks for being here.

THIS WEEK AT BEAR CREEK: Migrating Streams of Small Winged Beauties

Walnut in morning sun

What a glorious week for seeing migrating songbirds – and what frustration for a photographer who can’t quite manage to capture them all!  The trees, bushes and vines (like the Virginia Creeper on the right) are full of tiny, chirping birds that hop about quickly searching for sustenance before the next leg of their fall journeys.

I’ll share what I was able to photograph this week, with all the imperfections of an amateur photographer who, until this year, had almost no experience with warblers – who are very small and move very fast!

Blog post and photos by Cam Mannino

And then I’ll link you to better photos from Cornell Lab or Audubon.org, so you can see these little beauties up close – instead of half hidden by brush, silhouetted against the sun or at the very tops of trees!  So much color and energy in the park!  It’s a wonder how these small songbirds sail through the night and land in Bear Creek for a day’s rest and some fruits, seeds and insects to sustain them on the next leg of their journeys.

Winged Visitors : Warblers and Kinglets Everywhere!

If you’re looking for small migrating birds at Bear Creek, bring good binoculars and a lot of patience!  I learned a lot at Wednesday’s bird walk from Dr. Ben and  Ruth Glass who leads bird walks at Stoney Creek Metro Park and is a highly experienced birder.  For instance, they told us that in early morning,  it’s best to look for birds where the sun first hits the trees. (Makes sense, eh?)  So take the path into the park from Snell and once you get out in the field, look in the trees and bushes at the first large curve to the left.  Wow! Lots of birds in those bushes and trees!

Lane Oct. 4Other great places for me have been the Walnut Lane and the circuit all the way around the Playground Pond.  Walk slowly and very quietly and begin by listening to any cheeping in the bushes. Watch for twitching foliage and you’ll see them. But you need to go soon!  The migration for many songbirds peaked this week and numbers will decline until they are gone by early November.

Here’s a sampling of what you might see:

Palm Warblers (Setophaga palmarum) hopped from branch to branch again this week.  Look for their “field marks,” including a rusty cap, dark eye line,  breast streaks at the sides and yellow underparts. It’ll be leaving soon to go as far south as the Caribbean  – which could be where it got its name?

Palm Warbler 1

Palm Warblers are passing through the park. Look for their yellow underparts with streaking on the side and a rusty cap.

I caught sight of what I think is a Tennessee Warbler (Oreothlypis peregrina) going after some fruit.  It seems to be a male in its non-breeding, fall colors.  Page down to the bottom of this link for several different good views, including the non-breeding (fall) plumage.  Side note:  Last week’s Nashville Warbler (Oreothlypis ruficapilla) and this one aren’t necessarily from Tennessee.  According to Ruth Glass, they were first reported and drawn by John James Audubon who lived in Kentucky for part of his life and probably named birds for where he saw them.

The tiny, almost constantly moving Kinglets pass through Bear Creek during the spring and fall, too.   The flitting  Ruby-Crowned Kinglet is identified by its size, irregular white eye ring and its twitching wings!  Its “ruby crown” only shows when it’s excited or courting, though one of the birders saw a Kinglet’s crown this Wednesday!  Maybe you can see the tiny red dot on the head of this bird that I saw the next day – or you can  have a look at it really flared in this Audubon link.

I saw another Kinglet last weekend silhouetted in the sunlight and had no idea what it was until Ruth Glass identified it from my poor photo as a Golden-Crowned Kinglet (Regulus satrapa.)  Their field marks are a very short, thin beak perfect for winkling out insects and of course the gold on their wings and crown. Have a look at this Audubon link for a better view!

Winged Visitors:  Sparrows?  Yes!

I learned this year to stop ignoring small, brownish birds assuming they were all sparrows that I already knew.  That’s how I missed seeing other small migrants. Look at this beautiful White-throated Sparrow (Zonotrichia albicollis) with the bright yellow dots(called “lores”) in front of its eyes, a striped crown and of course, a white throat marked by black stripes called “whiskers” or “malar stripes”!

White throated sparrow closeup

Keep an eye on sparrows! Here’s a migrating White-throated Sparrow with a bright yellow dot in front of his eyes.

And here’s a young White-Crowned Sparrow  (Zonotrichia leucophrys ) which needs to be  differentiated from the White-Throated Sparrow above.  It’s about to make its first migration, because it was born somewhere in the far north below the arctic circle this very summer. (Thanks again to Ruth Glass for the ID!)

White-Crowned Sparrows look radically different after one year.  Here’s a photo I took at Bear Creek on October 6, 2008 and then a closeup of one at my house in spring a few years later.  Hard to believe it’s the same bird as the brown “first winter” bird in the photo above, isn’t it?

A White-Crowned Sparrow looks very different after its first year – and it breeds below the Arctic Circle!

Sharp-eyed Ruth also saw two Lincoln’s Sparrows (Melospiza lincolnii ) which look very much like a Song Sparrow (Melospiza melodia) but are smaller and daintier and have no central spot on their breasts. Unlike the courser streaking on a song sparrow, the Lincoln’s Sparrow’s black streaks are finer and on “buffy” flanks. Wikipedia says they are “quite secretive” – too much so,  for my eyes and camera!  So here’s another Cornell link to get a look.

The visiting summer sparrows that spent their summer in the park are still here too.  A Field Sparrow (Spizella pusilla) with its bright white eye ring and pinkish bill and feet watches other migrants hop in the trees. As their name implies,  Field Sparrows avoid suburban areas and will soon fly off to somewhere south of Michigan so keep an eye out for them soon at places like Bear Creek!

Field Sparrow

The Field Sparrow avoids suburban living so come see it in the park! It’ll migrate farther south for the winter, though it breeds here in the summer.

 Winged Migrants: a Mixture of Species

During the Wednesday bird walk, the treetops on Walnut Lane were filled with Pine Siskins (Spinus pinus).  This nomadic finch appears some years and not others as it follows the best seed crops.  My photo in morning sun in the treetops shows its streaky head and body but not the  flashes of its subdued winter yellow as they flutter or fly,  so have a look at Cornell Lab’s photo.

Down at the Center Pond, we saw an Eastern Phoebe (Sayornis phoebe) darting from the shore to the water, catching a few bugs.  The most distinguishing field mark of a Phoebe is a constantly pumping tail, plus a dark head and white breast.  The males usually sing “Phee-beee” only when courting but one was trying out its song on Wednesday. It probably spent the summer here.  It will be migrating in the next couple of weeks and be gone by early November.

Phoebe Center Pond

An Eastern Phoebe flitted between the shore and water catching insects for its migration in the next week or so.

At the western edge  of the pond on Wednesday, deep in the brush, skulked a migrating Hermit Thrush (Catharus guttatus) who probably raised its young farther north in Michigan or Canada.  These birds rummage in leaf litter looking for insects, so they can be hard to see. But the following day,  it appeared on a log near the pond.

Also at the pond, Ruth spotted a Blue-headed Vireo (Vireo solitarius) which may have spent the summer among pines farther north.  It generally looks blue-gray but Ruth told us it’s more blue in direct sunlight.  I love its white “spectacles.” Unfortunately, I didn’t get a shot of it but here’s the link to Cornell’s photo.

The Mallard (Anas platyrhynchos) males at the Center Pond are slowly getting rid of their eclipse plumage.  Here’s one whose beautiful green head feathers have almost completely molted.

Mallard almost finished molting

This male Mallard is almost finished molting, but his iridescent green head feathers still have a little way to go.

He’d probably like the molt to be over, since some of the males now have their full complement of courting plumage and are already pairing up with females, though mating won’t happen until spring!  They’ll move to the Gulf Coast this winter, unless they can find an area with sufficient food and open water farther north.

Mallard back to green

Some male Mallards have completed their fall molt and are pairing up with females, though mating won’t happen until spring.

The Gray Catbird raised its young here this summer but will be leaving soon, too.  This one in the vines and bushes north of the Playground Pond looks like it’s finished molting and is about ready to go.

Winter Residents (or Delayed Departures) Molting into Winter Garb

A flock of young Cedar Waxwings (Bombycilla cedrorum), who have left their fledgling feathers behind and now wear their first winter garb, jostled noisily among the fruiting vines and trees.  Some of them may remain here for at least part of the winter and then head south. I saw a flock of Waxwings at Bear Creek eating in ice-glazed branches on Christmas Eve two years ago! Others have already left for warmer climes, sometimes as far south as Central America.  These noisy young ones are identified by  mottled chests, shorter crests, and a wider white lines around the mask  – but the tips of their tails still glow bright yellow in sunlight like adult waxwings.

This female American Goldfinch (Spinus tristis) looks a bit disconcerted about molting into her drab winter colors, much like the female Cardinal that I posted last week.

This winter-ready Goldfinch, though,  looked as if it enjoyed its ride on a plume of Canada Goldenrod as it picked seeds from the dried blossoms as they swayed in the wind.

Odds ‘n’ Ends

A tiny Eastern Chipmunk ((Tamias striatus) dashed up a tree near Snell Road. I love how his tail was backlit by the late afternoon sun.

An Eastern Chipmunk near Snell Road

In the southernmost meadow near Snell, I spotted a large patch of white plants I’d never seen before.  Dr. Ben identified them as Fragrant Cudweed.  The University of Michigan Herbarium uses that common name or the slightly less bovine Old-Field Balsam.  Many internet sites call it Sweet Everlasting (my fave of the three) and look at  its Latin name – Pseudognaphalium obtusifolium – !!  Whatever you call this native plant, it’s interesting.  According to a Minnesota Wildflower site, the clusters of what look like egg-shaped buds are actually the blooms with the yellow/brown anthers (pollen- producing flower parts) exposed at the end.   And what looks like whorled petals are bracts, leaflike structures which will open and fall when the seed ripens. Nice to have fresh blooms so late in the year!  As the weather gets colder, we’ll really wish they were everlasting!

Sweet Everlasting or Cudweed

Cudweed or Sweet Everlasting blooming now in the southernmost meadow near Snell.

They may look like they’re buds, but they are the egg-shaped blooms of the Cudweed or Sweet Everlasting.

Fall migration must be a restless, exhausting, but exciting time for birds.  Their hormones, the shorter days, and the temperature all tell them it’s time to go south. Dangers lurk along the way, which is one of the reasons perching birds travel at night, avoiding raptors who travel by day.  Severe weather, a shopping mall where a woods used to be, lighted buildings that confuse the birds’ navigation systems can all be disastrous.  But the pull is strong and off these small birds go in the night, riding the wind if they can.  I hope you get to see some of them off.
