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

 

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

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

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

Birds are Plentiful, Colorful and Sometimes Difficult to See

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

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

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

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

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

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

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

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

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

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

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

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

A rather scruffy-looking, juvenile Wood-Pewee

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

Indigo Bunting

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

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

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

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

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

Prairie Wildflowers – What a Sight!

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

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

And we still have autumn flowers to look forward to!

That Carpet of Prairie Wildflowers Brought All Kinds of Butterflies!

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

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

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

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

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

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

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

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

Look for Red Admirals at Ilsley too!

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

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

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

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

Step by Step, Restoring Our Natural History

Eastern prairie at Charles Ilsley Park.

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

Cranberry Lake: Summer Ushers in Birds, Butterflies and Blossoms

Wild Geraniums along the Hickory Lane

 

Blog and Photos by Cam Mannino

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

Birds and Blooms in the Large Sunny Meadows

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

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

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

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

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

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

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

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

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

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

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

An American Copper butterfly rests on a grass stem between the multiplying Blackberry bushes.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Early Summer in the Shadowy Wetlands near Cranberry Lake

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

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

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

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

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

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

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

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

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

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

A Sandhill Crane at Cranberry Lake turns a wary eye my way

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

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

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

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

Nature by Ear as Well as by Eye

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

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

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.

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?

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.

The black-masked Common Yellowthroat is tough to see but easy to identify from its “Witchedy, witchedy” song.

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

Birds, Amphibians and Reptiles in the Leafy 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.

OUT AND ABOUT IN OAKLAND: Elusive Warblers and Summer Visitors

Hickory Lane at Cranberry_edited-1
Birding Group on a lane of Shagbark Hickory trees at Cranberry Lake Park

In the spring, when the leafing trees are full of warblers, it sure helps to have a birding group like our Wednesday Morning Bird Walks to provide trained ears and 14 eyes (or so) instead of just my 2!   Migrating birds ride south winds into our parks on their way north, with most birds moving through in April and May.  These temporary guests are small and move quickly about in brush or high in the trees.  Some birders, like Ben and our fellow birders, Antonio and Mark, can tell us which birds we’re hearing or they spot small movements in the treetops and show us where to point our binoculars.

In the last two weeks, I went looking for warblers and other avian visitors at  Cranberry Lake and Charles Ilsley  Parks.  Some are just passing through, some spending the summer.

Blog post and photos by Cam Mannino

As an amateur photographer, it’s a challenge to get decent pictures of these tiny, fast-moving bird guests, so please,  click on red links in this blog to see, or in some cases hear, birds that eluded my camera.  They’re beautifully diverse.  Who knows? Maybe you’ll recognize them in your yard or on your next walk.

Warblers  and Others Just Passing Through

According to Wikipedia,  English-speaking Europeans refer to their warblers, sparrows, and other small birds as “LBJ’s, ” meaning “little brown jobs.”  I used to ignore our “LBJ’s” thinking they were “just sparrows.” Turns out, sparrows can be beautiful too!  And our warblers here in North America come in all sorts of subtle colors, especially in the spring when they’re dressed for courting.  Here’s a beautiful Chestnut-sided Warbler (Setophaga pensylvanica) that the birding group saw at Cranberry Lake Park.

Chestnut-sided Warbler 3

During the winter, this little male hung out with tropical warblers in the Caribbean or Central America.  After traveling so far, it’s no wonder he needed to stock up on food and rest on his way to breeding grounds farther north.

We spotted the  Northern Parula  warbler (Setophaga americana),  but it just wouldn’t come out for my camera. Even Cornell Lab’s photo doesn’t do it justice, because its gray is much bluer in morning light and its back has a green patch – plus those rusty stripes on a golden throat! (Look at “Field Marks” lower on the page for a better shot.)  No LBJ, I’d say!

We heard the “squeaky wheel” call of the Black-and-white Warbler (Mniotilta varia) before we saw this little bird. It creeps along the bark like a nuthatch looking for insects. What a snappy dresser in those bold pin-stripe feathers! Listen to him here at “Typical Voice” about halfway down the page.

Black and white warbler
The Black-and-white Warbler moves like a nuthatch along branches.

For a bit of warm sunshine on a gray day, listen for the Yellow Warbler (Setophaga petechia). The male’s quick song , recorded at Cranberry Lake Park by Antonio Xeira and posted on the Xeno-Cantu site, sounds to some folks like a repetition of “Sweet, sweet, I’m a little sweet!”   – very appropriate for this bright yellow bird with a rusty-striped breast. Yellow warblers can be found in wetlands in our parks throughout the summer.

Yellow warbler2 Cranberry
The Yellow Warbler is difficult to see but his song “Sweet, sweet, I’m a Little Sweet” announces his presence.

The Nashville Warbler (Oreothlypis ruficapilla) isn’t quite as glamorous but it’s definitely not an LBJ.  These small birds with their eye rings, gray backs and yellow breasts travel north to pine forests where they make their nests out of moss, bark and pine needles, or sometimes, according to the Cornell Lab, even porcupine quills!  Here’s a photo I took of one at Bear Creek last fall.

Nashville warbler
The Nashville Warbler travels farther north and makes a nest of moss, bark and pine needles.

The modest Tennessee Warbler (Oreothlypis peregrina) looks much more subdued.  Both were named for the place they were first sighted and both stopped at Cranberry  Lake Park this spring.

Ben heard or saw some other warblers in the two parks that I haven’t seen this spring. Have a look at the Blue-winged Warbler (Vermivora cyanoptera), seen at both Cranberry Lake and Ilsley Parks, whose wings look gray in some light (as in the photo) and blue/gray at other times.  Or the Black-throated Green Warbler, an olive-green bird with a black throat and black stripes down the side of its breast.  Ben always identifies this warbler by its buzzing call, which some folks describe as “zoo-zee, zoo,zoo, zee.” Listen here for the insect-like call (middle of page under “Typical Voice.”).   The Magnolia Warbler  (Setophaga magnolia), with its bright yellow head and  black-striped breast, also stopped by Cranberry Lake Park.  Isn’t it great that our parks provide food and rest for these little travelers ?

Even our sparrow visitors are not just LBJ’s!  Have a look at the boldly striped cap of this White-crowned Sparrow(Zonotrichia leucophrys)at Charles Ilsley Park.  In the second photo, he’s munching off dandelion seeds.  See, those puffs in your lawn are food to some of our avian visitors!

 

Guests That Spend the Summer With Us

The parks are filling, as well, with migrating birds that come to our parks to nest and raise their young.  One of the smallest (and hardest to photograph) is one that I think should be called “The Bandit Bird.”  But unfortunately,  this warbler’s name is the Common Yellowthroat (Geothlypis trichas), another bright yellow bird, but this little bird has a black mask across its eyes.  Like any good bandit, the Yellowthroat skulks in tangled vines and branches often near marshy areas.  The males, though, give their presence away with a very distinctive call of “Witchety, witchety, witchety” as heard here in Antonio’s recording. (Click on images to enlarge; hover cursor for captions.)

Some larger summer guests have arrived in the parks, as well.  We saw an Indigo Bunting (Passerina cyanea) at Cranberry Lake but it was down in the grass near the parking lot – so here’s a previous spring’s photo from Bear Creek.

Ben and some other birders saw a Scarlet Tanager (Piranga olivacea)at Cranberry Lake before I arrived – drat!  But here’s a photo from a previous spring at Bear Creek.  This  beautiful bird traveled all the way from South America just to raise young here in Oakland Township.

A Scarlet Tanager – what color!

The nesting boxes are busy at Charles Ilsley Park.  Here a Tree Swallow (Tachycineta bicolor) stands guard at one of them.

Nearby, its Eastern Bluebird neighbor, who may have stuck around all winter or arrived much earlier in the year, was out plucking what looks like a caterpillar from a plant and delivering to his presumably nesting mate.

The glorious Baltimore Orioles were in both parks that I visited.  The male’s pure, high whistle can be heard high in the treetops as he and his mate search for a spot, usually near water, to weave its bag-like nest that will rock its young in the wind.

Time and Migration Wait for No Man…or Woman Either!

Old field Ilysley

The rolling slopes of Ilsley Park, with its golden dandelion-strewn paths, await!  If you can spare the time, join the Wednesday morning bird walks listed under the Stewardship Events tab above.  Ben will provide binoculars and his expertise  and the easy-going birders will welcome you.  So will the glorious avian visitors either enjoying a little R&R before moving on or settling in to raise a family.  But many of the warblers will only be here a few more days.  So come have a look!

THIS WEEK AT BEAR CREEK: Native Wildflowers With Wet Feet – Plus Tiny Birds and Froggy Goes a-Courtin’

Well, High Summer in spades, eh?  Ninety degrees!  In the hot sun, buds are bursting all around Bear Creek, especially on plants that have made the township home for  millennia – our native wildflowers.

Blog post and photos by Cam Mannino

Small birds venture out in the heat – some to take dust baths and some just practicing their foraging skills.  A small adult bird sings farewell, while other small birds are just beginning to nest! The soon-to-be-grown grasshopper nymphs camouflage perfectly in the dust at our feet while frogs bulge with amorous thrums as they start their courtship percussion.  So much to see and hear if  you can take the heat!

 

It might be best to come early in the morning and take a stroll down the sloped path on the park’s western side.  After a blistering day and a cooler night, heavy dew sparkles at the tip of every plant and bejewels the elaborate webs that spiders wove the day before.

Native “Wet-Footed” Wildflowers Love Park Wetlands

Speaking of jewels, here’s a lovely native flower that flourishes now in moist areas of the park.   It’s called Orange Jewel Weed (Impatiens capensis) and here’s one bedazzled with early morning dew.

jewel weed
Jewel Weed wearing its own jewels in morning dew.

Jewel Weed is also called Spotted Touch-Me-Not because once it’s mature, the seeds will explode from thin, green-striped pods.  Here’s a link to a 47 second YouTube  video Ben posted earlier that shows this wild flinging of seeds!  Watch to the end to see it in slow motion.

Buttonbush (Cephalanthus occidentalis), a native shrub that loves wet feet, bursts with sputnik-like blooms near the southern deck in the Big Marsh and in the smaller marsh just north of the playground.  Look at all those tempting individual flowerlets for the bees and butterflies!

The sputnik-like bloom of a wet-footed shrub called Buttonbush.

Close by, on the opposite side of the boardwalk in the marsh north of the playground is one of my favorite native wildflowers, Cardinal Flower/Red Lobelia (Lobelia cardinalis), which always blooms in this area of the park in August.  It’s pollinated by hummingbirds who love red as much as I do.

Cardinal Flowers bloom near the marsh north of the playground every August and they’re pollinated by hummingbirds!

Joe Pye Weed (Eutrochium maculatum) sinks its roots in the moist ground near the deck at the southern end of the Big Marsh and this year along the eastern path as well.  There are various  legends about the origin of the name, which is purportedly connected with a Native American healer.  This plant, which I had confused with Swamp Milkweed (before Maryann Whitman set me straight!), has dark purple stems rather than the green ones of Swamp Milkweed which I posted two weeks ago as it was hosting a Monarch butterfly.  

Joe Pye Weed
Native Joe Pye Weed is identified by its dark purple stem, pink blooms and love of wet places.

Long stems of native Showy Tick Trefoil (Desmodium canadense) bloom, too, in the moist soil at the edges of wetlands in the park, though as a prairie plant it can grow in drier spots as well.  The plant has long curving stems and is a bit leggy:

A native plant, Showy Tick Trefoil, grows 2-6 ft. tall.

Now look up close.  It’s individual flowers are beautiful.  The details in nature are frequently worth a closer look.

Blossoms of show tick trefoil
Showy Tick Trefoil blossoms deserve the name when you stop to look closely.

I learned from Ben that, happily, the cat-tails we see growing in moist areas and marshes around Bear Creek are native ones, called Common Cat-tails (Typha latifolia).  This species grows all over the world,  from sea level to 7500 feet!  Cat-tails contribute to the cleansing effect of wetlands by absorbing pollutants in the water.   Ben tells me that the way to distinguish native cat-tails from invasive  cat-tails,  which do occur in Michigan, is that the invasives have a space between the male part of the plant (at the top) and the female part (just beneath) which is the part that turns fluffy in the autumn.  Our native ones have the male part directly above the female.

Our native cat-tails contribute to the cleansing effect of wetlands by absorbing pollutants.

Froggy is a-Courtin’ All Right!

At the Center Pond, the male Green Frogs (Rani Clamitans) are thrumming away, establishing little territories and competing for partners. Here’s a view of one of the 50 or so frogs visible on the pond surface this week – and he’s just about to croak.

And now one in mid-croak!

A Green Frog mid-croak!

The Center Pond was a peaceful spot for listening on a hot morning.  A Muskrat cruised beneath the overhanging branches at the eastern end.  The two Wood Duck siblings were still hanging out together, one standing on one leg for reasons which are never clear to me.  Bees and hover flies buzzed by, dragonflies patrolled and the occasional trill of  goldfinch song made the morning complete.   Hope you can hear some of this on my amateur recording. You might want to turn up your volume to hear the birds in the background.

Tiny Avian “Teenagers”

For some reason, the smallest birds seemed to be most evident on a hot morning.  On the Walnut Lane, two juvenile House Wrens (Troglodytes aedon) took a dust bath, no doubt trying to rid themselves of the mites that pester birds this time of year.  Wren adults often put spider egg casings in their nests so the spiders will consume the mites that bother the nestlings.   But once out of the nest, the young have to cope with them on their own.

A fledgling wren settles into the dust for a bath, trying to rid itself of pesky mites beneath its feathers.

A little wren spreads its wing as it takes a vigorous dust bath.

The male wren sings beautifully in the spring and summer when he is courting. Have a listen at this link where it says “Typical Voice.” Once the nestlings are born, his song is much softer and shorter.

Male wren singing
A male wren sings exuberantly when courting (listen at link above) but becomes softer and shorter once the nestlings are born.

During nesting, you’ll see males and females neatly carrying little fecal sacks, like diapers, out of the nest to keep it tidy as they fly back and forth to feed the young.  The adults defend the nest, scolding vigorously if an an intruder comes near.  Once the nestlings fledge, the pair stays with them and feeds them for a couple of weeks.  The female may then head off to start a second brood with her first partner or another.  The male cleans out old nests in the area as potential sites and begins singing again.  The young, like the dust bathing ones above, are generally hard to see – very quiet, huddling in the leaves in low bushes.

Another tiny fledgling , the Blue-gray Gnatcatcher (Polioptila caerulea) hopped in the branches along the path leading into the park from Snell.  Perhaps you can see how tentative it looks; it may be out on its own for the first time. But no doubt the adults are close by, keeping an eye on their fledgling and feeding as necessary.

In this shot, the juvenile Gnatcatcher’s white eye ring is more visible. No doubt its parents are quiet in nearby bushes either feeding siblings or waiting to see how this one does on its own.

Small, Yellow Adults Sing  – One Saying Goodbye, Another Still Nesting!

Although not a juvenile, another tiny bird is singing its farewells all over the park.  I mentioned the Common Yellowthroat (Geothlypis trichas)  in the spring when its bright yellow breast and black mask are easier to see in the bare branches.  I cannot seem to spot it among the leaves now, but I often hear its “witchety, witchety, witchety” call (hear “Typical Voice” at this link) when I ‘ve been near water in the park lately.  Listen soon, because Yellowthroats molt in early August and after that, they leave us for warmer climes.

common yellowthroat
The Common Yellowthroat isn’t easily seen now, but its “witchedy, witchedy, witchedy” song is heard in the park as it prepares to molt and leave us.

American Goldfinches (Spinus tristis) are nesting now, when thistle down is available for lining the nest and thistle seed, a preferred food, is available to feed the young.  The males are singing shorter songs than they did when pairing up and establishing territory in the spring.  But surprisingly,  both male and female Goldfinches sing while flying, a rare thing in the bird world.  It pays to stop and listen when you see their  bobbing, undulating flight or watch them balancing on a thin stalk to eat seed.

Goldfinches have their young later in the summer than other birds, using thistle down to line nests and thistle seed as a preferred food source.

Coming Attractions:

August is the time for grasshoppers galore!  This week I think I spotted the pale instar (immature stage of metamorphosis) of a Carolina Grasshopper (Dissosteira carolina).  I only saw it because I spotted its black/brown wings in short flight at my feet.  Once it landed , it was beautifully camouflaged in the gray dust of the trail, looking like a dry stick among the pebbles and short grass.  But if I’m right, before long, it will molt again into the big cinnamon brown body it sports in August. Though I diligently perused the amazing grasshopper reference book provided by a commenter, I still cannot be sure about grasshopper ID’s – so feel free to set me straight!

And what I think are the smaller instars of the Red-legged Grasshopper (Melanoplus femurrubrum) spring here and there in the grass as well.  When fully developed later in August, it will have a green head, golden abdomen and bright red legs –  if I’ve identified it correctly!

A tiny instar (immature stage) of a Red-legged Grasshopper will metamorphose in stages into a truly red-legged adult.

So come out in the earlier morning to enjoy the dew drops or brave the heat at midday if you relish summer sun.  There’s always something to surprise and delight you at Bear Creek.

This Week at Bear Creek: Big Beautiful Birds, Blooms and Butterflies

Well, the best-laid plans, as they say…April 28, I fell and fractured my sacrum. After spending a few very painful days in hospital, I learned that there’s no repairing such a break; I just have to wait 3 months or so for it to heal.

I’ve missed a week of this blog and thought this accident meant a very long hiatus in “This Week at Bear Creek” since I won’t be walking in the park until sometime late this summer. But I’ve come up with a plan which I hope meets with your approval. Since I’ve walked in Bear Creek and taken photos there for so many years, I have a huge library of photos. And since the photos are dated, I know when various creatures have appeared there in the past.

So my plan is to provide you with a photo guide to what to look for every week (or two, as able), based on past Bear Creek springs and summers. And perhaps some of you, along with Dr. Ben and my husband Reg, will tell me what you saw and I can pass along that info as well. So, here we go:


 MAY 10- 16, 2015

Two glamorous birds arrived in our area this week.   Both the male and female Rose-Breasted Grosbeak (Pheucticus ludovicianus) alighted in the park this week – and both are stunning. Since they sing from high in the treetops when leaves are just bursting forth , they’re not easy to spot. Listen for a melodious mixture of high and low notes that’s been described as “a Robin who’s had voice lessons.” Here’s one I saw at home on May 8 a few years ago.

Like the Seven Dwarves, the female grosbeak whistles while she works, building her nest, which isn’t common for female birds. With her heavily-streaked breast and the bright white line above her eye and necklacing her throat, the female grosbeak can be mistaken for a female Red-wing Blackbird. But “grosbeak” is an appropriate name; these birds have short, heavy beaks. I’ve spotted them over several years in the eastern side of the woods, near the marsh. Here’s a link to the female’s appearance:

And here’s another for their sweet song:

The other glamorpuss that’s just arrived is the Baltimore Oriole (Icterus galbula). The male’s eye-popping orange, black and white plumage is unmistakable. The females usually are more yellow than the male’s brilliant orange but they become more orange each time they molt. When they arrive from Central America, they are looking for quick energy and love fruit – but only dark red, orange or purple fruit. (Very particular birds!) That’s when they come to backyard feeders filled with grape jelly or half an orange. When raising young, they hunt insects for the protein they need for themselves and their nestlings and are less visible. So here’s one singing its melodious whistle high in the trees near the center pond and then a closeup as one horns in on our hummingbird feeder.

Maybe with luck, you’ll see them building their sack-like nest right at the tip of a branch very high off the ground, literally rockaby-ing their babies in the treetops.

Dr. Ben saw an amazing 35 separate species on a Bear Creek bird walk last week! And what a group! 8 different warblers and many of them were seen by sitting quietly on the boardwalk just off the playground early in the morning. Here’s one of them who graces the wet areas of the park all summer.

It’s the Common Yellowthroat (Geothlypis trichas), a small masked bird who usually hangs out near the center pond or marsh. If you can’t see it, you can hear its distinctive “Witchedy-witchedy-witchedy” call. Have a listen:

One of my favorite fisher birds arrived this week too, the Green Heron (Butorides verescens). Ben saw a pair posing quite calmly in a tree at the center pond. Like other herons, it’s a very patient fisher. It stares intently down into the water until it spots its prey – a small fish or frog. And then dives headfirst into the water – Gulp! – And it’s gone. I saw this one at the center pond last fall :

You may notice groups of young Blue Jays (Cyanocitta cristata) hanging around in the bushes on the north side of the park, giving each other a hard time, jumping from limb to limb, darting through the trees, and generally acting like teenagers. I’ve just learned young blue jays don’t breed their first year but form groups and practice courtship behavior. Here’s an adult blue jay who seems to be looking a bit askance at all their silliness.

The strange and wonderful buds of the Shagbark Hickory (Carya ovata) are pushing their way through the branches. Keep an eye out for them on a tree whose distinctive bark makes it a special feature of Bear Creek.

The May Apples (Podophyllum peltatum ) have unfurled their umbrellas and can be found in groups underneath tall trees in wooded areas all over the park.

Jack-in-the-Pulpit (Arisaema triphyllum) sits proudly inside his green lectern all over the woods. Being a native plant, these little preachers should thrive after this spring’s prescribed burn.

A tiny, early butterfly is fluttering through the grass right now. Spring Azures (Celastrina ladon) are easy to spot with their lavender blue wings and whimsical black and white striped antennae. When feeding, they fold their wings upward so that the drab gray undersides will make them more inconspicuous to predators.

Coming Attractions

A native beauty, the Large-Flowered Trillium (Trillium grandiflorum), has pushed its trio of leaf-like bracts through the soil and have unfolded their showy white petals.  Look for them to the west side of the boardwalk on the eastern side of the center pond and to the west side of the Eagle Scout bridge as you enter the western woods. They usually bloom in Bear Creek a bit later than elsewhere.

Watch this coming week for the lavender carpet of Wild Geraniums (Geranium maculatum). Ben tells me that with this warm spell, they should start blooming quickly. Here’s how they looked last year in the second week of May but there may be more this year after the prescribed burn.

So I may be housebound, but we still can share the beauty of Bear Creek Park. I value your input, so please, fellow nature lovers, lend me your ears – and your eyes!
