Back to Bear Creek: Surprise! Unusual Sightings of Birds, Bugs and More

Blog Post & Photos by Cam Mannino

The last two weeks at Bear Creek gifted me with some exciting moments – seeing previously unseen birds, witnessing unusual nesting behavior, watching a turtle struggling to bury her eggs and being surprised by a little butterfly I hadn’t seen for years. So though the blog just visited Bear Creek two weeks ago, I wanted to share the bounty I’m enjoying before the season changes much.

Unusual Birds and the Usual Ones Doing Interesting Things!

As many of you know, I’ve been walking in Bear Creek for 25 years and I’ve watched for owls all that time. They spend their days sleeping right next to tree trunks on high limbs, and despite craning my neck for years, I’d never spotted one. But on the first June bird walk, a fellow birder, Bob Bonin,  spotted one high up in a tree near Bear Creek Marsh. Huge, silhouetted against the morning sky, this Great Horned Owl (Bubo virginianus) wasn’t easy to see, much less photograph. But luckily, I got a few shots before he gave the group an annoyed look, lifted his huge body with his massive wings and flew away. Such a thrill! (Click on arrows for slideshow; use pause button for a closer look.)

A bit earlier that morning, we saw an unusual bird at the other end of the size spectrum. A male Ruby-throated Hummingbird (Archilochus colubris) perched high on a snag behind the Center Pond and turned his iridescent green back to the morning sun. We saw a quick orange flash at his throat but I missed it. The Stokes Guide to Bird Behavior (Vol. I) indicates that males’ throats look brown or black if the light doesn’t hit their necks just right. When I returned on a late afternoon, there he was on the same snag – but this time the afternoon sun caught the edge of his throat which shone gold rather than ruby red. He’s not the most glamorous hummer, but I’m glad I got to see a bit of his gleam.

This male hummingbird’s bright throat only shone for a second in the morning sun, so I settled for the light in his eye and his iridescent green back.
The same male hummer’s throat shone gold in the late afternoon sun.

Near the Center Pond, the birders also discovered the nest of a Rose-breasted Grosbeak (Pheucticus ludovicianus) – with the male sitting calmly, tending the eggs or nestlings. Occasionally, he even sang his lovely tune as he waited patiently. I’d read in the Stokes Guides that male Grosbeaks sometime take on this responsibility, but I’d never seen it. On three separate visits, the male was the only one on this nest – though the female may have relieved him at other times. So, Happy Father’s Day to this dedicated Grosbeak dad!

In a willow to the right of the deck in the Center Pond is a beautiful nest.  It’s cleverly attached between two vertical branches about 20 feet up, ingeniously woven and quite large – maybe 9 inches long. During my first 3 visits, only the female’s black tail cocked behind her was visible from the observation deck. Finally one afternoon, I waded into the grass at the pond’s edge and  caught sight of her hindquarters as she fed her young. And then, I saw a fledgling’s head just above the edge of the nest. Ah, this nest was constructed by a female Red-winged Blackbird (Agelaius phoeniceus) – a somewhat eccentric one since Red-wings normally build close to the water and weave their nests among cat-tails or reeds. She’s quite an architect! The location of this elaborate nest makes it nearly invisible and unreachable by predators. Clever mama Red-wing!

Two nests appeared high in a tree on the Walnut Lane. The barely visible, masked eye of the female Cedar Waxwing (Bombycilla cedrorum) peeked through the leaves that camouflaged the first nest spotted by the birders. Since she sat there quietly every time I visited, I’ve included a photo of a Waxwing from a previous year so you’ll  remember how elegant this conscientious mother bird truly is!

Only the masked eye of the female Cedar Waxwing shows above the edge of her cleverly hidden nest along the Walnut Lane.

Across the Walnut Lane, the birders also discovered the nest of a female Eastern Kingbird (Tyrannus tyrannus) who spent several days building her gauzy, somewhat more loosely constructed nest. She proudly stood above it a few days later as it neared completion. The female Kingbird constructs the nest and keeps the male off it until the eggs hatch. Then both parents feed the nestlings. But even during the egg phase, the male stays on a branch nearby to defend the territory for his mate and young.

Another good provider, a tiny male Yellow Warbler (Setophaga petechia) brought a bright green caterpillar to feed his nestlings or mate. In between feeding trips, he’d let loose with his proud song, “Sweet, sweet, I’m a little sweet.” Impressive dad who can bring home the bugs, singing all the while! Bet the female warbler was as impressed as I was.

An Orchard Oriole male (Icterus spurius) serenaded us from a small tree in the middle of a meadow. His long, melodious song sounded much like the third song recorded at this link.  A few Orchard Orioles seem to come to Bear Creek each year – but they migrate south by mid-July. So keep an eye out and an ear cocked soon in the meadows to the east of the Walnut Lane!

An invisible bird, high up in the tree tops, repeated its melodious warble continuously one warm morning. I’ve never seen a Warbling Vireo (Vireo gilvus); they rarely come down from the heights. But fortunately, a great photographer from the iNaturalist website, Steven Mlodinow, has seen one and generously allows others to borrow his photo. Listen for this warbler’s rich melody all summer long, but don’t be surprised if you never spot this elusive summer resident.

Little Surprises Near the Wetlands

At the northeast corner of the Center Pond, a young Painted Turtle (Chrysemys picta) hurried to cover her eggs one hot afternoon. She’s found a likely spot where Ben had cleared away invasive shrubs a couple of years ago. As you’ll see in the video below, she work really hard with her back legs to get the dirt to move. She’d no doubt have preferred sandier soil! But she was determined to see the job done!

I’ve seen Northern Leopard Frogs (Lithobates pipiens) periodically at Cranberry Lake but never one at Bear Creek. But hearing their snoring call near a wetland, I waded into tall grass and found this one, hiding among the greenery. Glad to know this beautiful frog is at Bear Creek, too.

Ben noticed an  Eastern American Toad (Anaxyrus americanus) toad on the path one afternoon when we went to look at nests.  Normally, I only see brown toads, but Wikipedia informs me that “The color and pattern is somewhat variable, especially for the females. Skin color can change depending on habitat colors, humidity, stress, and temperature…Some toads of this subspecies have a more pervasive red and deep brown color, many with red warts on their bodies.”  So this little toad is probably female and the red description  fits  her pretty well.  I wonder if the unusually hot temperatures had an effect on her appearance?  Hard to tell.

Amazing Insects: A Butterfly I’ve Missed for Years, Favorite Dragonflies and the Skills of Tiny Pollinators

Next year, I’ll be looking for the boldly patterned Baltimore Checkerspot butterflies (Euphydryas phaeton) on June 11 or 12. I’ve only seen them on those two dates, 6 years apart! This year, four of them fluttered at a spot in the trail where water runs under the path – a place I’ve often seen other small butterflies feeding on minerals left by the water. Later in the summer, watch for the communal caterpillar webs of these small butterflies (about 2.5 inches) on the host wildflower Turtlehead (Chelone glabra) where these butterflies lay their eggs during the summer and where the caterpillars first feed.

Interestingly, in the fall, Baltimore Checkerspot caterpillars wrap themselves in leaf litter, overwinter and finish developing in the spring. This seems to be a big year for them – so keep an eye out if you see a small, dark butterfly at your feet.

The Baltimore Checkerspot overwinters as a caterpillar.

Different species of dragonflies seem to appear each week to dance among the budding wildflowers and over the pond. The dramatic, yet quite common Twelve-spotted Skimmer (Libellula pulchella) did indeed skim over the tops of grasses in the Eastern Meadow this week. Dragonflies often land, fly, and then come back to the same dry stalk – so if you miss one in your binoculars the first time, wait a moment and you’ll probably see it in the same place again!

A bright green Eastern Pondhawk (Erythemis simplicicollis) dragonfly clung to a grass stem on the western slope. If it’s a male, it will gradually turn blue over the summer. If a female, it will remain green. Probably this one is newly emerged since it’s hunting in a meadow. When it’s ready to mate, it will rendezvous with others  at the Center Pond.

This Eastern Pondhawk is still in the meadow but will go to the pond when it’s time to mate.

A small Dot-tailed Whiteface (Leucorrhinia intacta) dragonfly posed for a face-on selfie at the Playground Pond before continuing its quest to consume as many mosquitoes, flies and other small insects as possible before the day is out. Love its cartoon-like face and the one yellow dot on its tail that give it its name.

Easy to see why this is called a Dot-tailed Whiteface dragonfly, eh?

 

 

 

 

 

 

 

 

 

 

Pollinators are busy all over the park, feeding and carrying the pollen that will bring us next year’s blooms. This may look like a European Honey Bee (Apis mellifera) but Honey Bees are fuzzy all over and this one just isn’t. So it’s more likely to be a Dronefly (Eristalis tenax), a type of Hoverfly (family Syrphidae), which uses its pattern, slight fuzziness and loud hum to mimic male Honey Bees as a way of protecting against predators. Droneflies cannot sting, but a passing dragonfly probably doesn’t take a chance!

This dronefly (a kind of hoverfly) mimicks a bee’s appearance and hum for protection.

I noticed what looked at first like a tiny wasp on this umbel of a native Nannyberry bush (Viburnum lentago) near the Center Pond. But after a bit of research in Pollinators of Native Plants by Heather Holm, I’m going to guess it’s a female Leaf-cutter Bee (family Megachilidae). It has a wasp-y pattern and shape and it’s collecting pollen on its abdomen and on the top of its back leg (look at those jodhpurs!). Leaf-cutters cut small, neat circles out of leaves, hence the name. They then roll up a single fertilized egg and a chunk of pollen in each circle, forming a solitary, cigar-shaped nest which is placed in a hole in the soil, wood or other structures. Such an unusual nest!

Bring a Friend – or Friends! – to Visit Your Favorite Park

Oakland Township Natural Areas manager Ben VanderWeide leads a group of birders at Cranberry Lake Park

I’ve always loved walking alone in the township parks. I can listen to birdsong, stop to look at something tiny like the Little Wood Satyr butterfly below, or enjoy the fresh scents of wood, greenery, the earth after a rain in silence. Solitary walks are contemplative.

But this particular blog testifies to the special pleasures of hiking with interested friends and family. First of all, they just bring more eyes! I’m always seeing things with the birders or with my husband, that I’d never have noticed with just my two eyes (in this case, the owl, the hummer, the oriole, the male grosbeak in his nest and more). But also their curiosity piques mine. They bring specialized interests and knowledge. They often patiently help me find the bird hiding in a leafy tree (“The center trunk at about 2 o’clock…). It’s a different kind of delight to walk with nature-noticing friends. So if all of this nature stuff intrigues you, take some nature-lovers with you on your next walk. Or consider joining our friendly birding group on Wednesday mornings year ’round. We’d love to have you join us! (The schedule is under “Events” at the top of the home page.)

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 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.

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.

Bear Creek Nature Park: Little Spring Dramas Everywhere You Look

Native choke berry shrubs (Prunus virginiana) burst with blooms to attract  pollinators before the trees leaf out.
Blog and photos by Cam Mannino

Late April and early May are full of dramas. Birds hassle each other over territories. Some turn their brightest feathers into the sunlight or sing elaborately constructed songs  to impress the ladies. Snapping turtles roil the waters of the marsh as they twist and turn with their partners, butting heads and biting as they perform their mating dance. Late spring wildflowers and smaller trees hurry to show their best blooms to attract pollinators before bigger trees cloak them in shade. It’s a bustling, slightly crazy season – and isn’t it great?

 

Migrating Summer Birds Busy Courting, Hassling and Scouting for Nests

Down at the Center Pond one cool spring morning, the birding group watched a Green Heron (Butorides virescens) warming itself on a log at one end of the pond.  Its neck wasn’t stretched over the water, so it wasn’t seriously fishing; it just sat there peaceably. Gradually,  a pair of passive-aggressive Canada Geese (Branta canadensis) noticed its presence and decided, evidently, that they wanted the pond to themselves. They cruised slowly up to the heron until one of them was nearly beak to beak with it. The heron just sat. They joined forces and approached together. The heron just sat. Finally, one goose climbed onto the heron’s log, while the other positioned itself directly in front of the hapless heron. It sat for another minute and then finally acquiesced, fluttering off to the muddy shore nearby. Conflict successfully avoided, it probably found plenty of snails, insects and amphibians to eat while waiting for the geese to depart.

Sometimes the ongoing drama is a little less obvious.  Rose-breasted Grosbeaks (Pheucticus ludovicianus) are plentiful in Bear Creek this year. One morning a male turned his bright pink breast patch to the sun and trilled his elaborate spring song repeatedly for his more modestly dressed mate. (If you hear a fancy version of the robin’s song, there’s likely to be a male grosbeak nearby.)

A male Rose-breasted Grosbeak uses his bright pink breast patch and his elaborate song to attract his mate.
A female Rose-breasted Grosbeak listens to the male’s operatic song.

But nearby, there’s a careful observer. The female Brown-headed Cowbird (Molothrus ater) is high in a tree listening, too.

A female Cowbird high in a tree watching to see if a likely bird builds a nest in which she can lay her eggs. The Grosbeak’s perhaps?

She’s watching for a likely nest in which to lay her eggs. Maybe she’s hoping  the grosbeaks will be the ones to nurture and raise her young. Fortunately, the grosbeaks aren’t great prospects. They’re big enough to push the eggs out of the nest – if they notice them. Some birds do and some don’t. The drama hasn’t reached Act II.

In the small meadow west of the pond, a male Gray Catbird (Dumetella carolinensis) spent the morning stringing together short phrases – whistles, tweets, trills and  imitations of birds, frogs, even occasionally machinery!  His complicated song can go on for minutes without repetition! This male combined song with ruffling his feathers and chasing after the female who was playing hard-to-get. She’d stop to listen, fly off and then dart toward him. He’d pursue her, fluff his feathers again and sing something new. And on they went at the forest edge and among the meadow’s small trees and shrubs.

The male catbird taking a quick pause before ruffling his feathers and breaking into elaborate song.

Some migrators arrive in busy flocks, just stopping over for a short while to refuel before flying north. This week, a flock of 6 or 7 White-Crowned Sparrows (Zonotrichia leucophrys) rode in on a south wind during the night and spent the morning gobbling whatever they could find at the edge of the trails. Such a handsome little sparrow with its striped crown!

A small flock of White-Crowned Sparrows stopped to forage at Bear Creek on their way to cooler nesting grounds farther north.

Some birds fly in for just a short time to breed and then return to southern climes. This Orchard Oriole (Icterus spurius), the smallest of the orioles, flitted quickly among the branches, nibbling on sweet leaf buds for a little quick energy. Even if he finds his yellow-green mate and nests, he’ll likely be gone by mid-July – back to his favorite haunts in Central America.

The smaller, russet-colored Orchard Oriole may nest here, but will leave by mid-July for Central America where he spends the rest of the year.

High overhead, a pair of Sandhill Cranes croaked their wild cry, sounding and looking like two prehistoric pterodactyls with their giant wings. (Click on photos to enlarge; hover cursor for captions.)

The warblers, the tiniest of migrants, have begun to arrive.  A week ago a fellow birder helped me spot two species – the Yellow-rumped Warbler (Setophaga coronata) and the Yellow Warbler (Setophaga petechia) – and, we think, a Ruby-crowned Kinglet (Regulus calendula.) I didn’t manage to take any decent photos since some ate high in the tree tops and others hopped madly from limb to limb nibbling on leaf buds. So here are three photos from last year just to jog your memory.

In the western meadow, an Eastern Kingbird (Tyrannus tyrannus) paused on a stalk. Kingbirds have a crown of red, orange or yellow feathers under that black cap, but they only show when they’re attacking a predator. I’ve never seen them. According to Cornell lab, this solitary, feisty bird changes his lifestyle in the winter, traveling in flocks all along the Amazon and eating fruit instead of Michigan insects. A favorite photo below from a few years ago shows his crown just slightly raised and his red gaping mouth.  Maybe he’s feeling just a wee bit aggressive?

The Eastern Kingbird has colored feathers under that black cap that show when he’s aggressive toward a predator.

Drama in the Wetlands as Well

Over in the marsh, a very small Snapping Turtle (Chelydra serpentina) and a MUCH larger one roiled the water at the far end of the marsh. The difference in their neck lengths will help you determine their relative size in the photos.

I assume the smaller one was the male as he attempted to mount the back of the female’s huge shell at one point.   Snappers generally do a lot of face biting when they mate, sometimes injuring each other. The photo below may look like a kiss but it’s more likely that the small turtle on the left is approaching to bite some indeterminable body part of the larger on the right. It didn’t look as though things worked out too well for either of them. After some rolling and tumbling in the marsh, the smaller swam off and the larger floated calmly in the distance.

What looks like a turtle kiss may actually be a bite that the smaller turtle (left) is giving the larger as part of the attempted mating process.

Blue-spotted Salamanders ((Ambystoma laterale) reproduce in a less excited manner. According to the Michigan Department of Natural Resources, salamanders emerge from their burrows on the night of the first snow-melting rain (now that would be dramatic to witness!) and go to the nearest vernal pool After a little nudging and hugging, the male deposits a sperm-topped cone of jelly on the ground in front of the female. She takes it in to fertilize her eggs, which are laid in the water in the next day or so. By mid-summer, the hatched tadpole-like larvae develop lungs instead of gills and absorb their tail fins, taking adult form.  Red-backed Salamanders (Plethodon cinereus) lay their eggs in burrows and their young hatch as miniature adults. Here are some salamander eggs and a salamander larvae/tadpole that the monitoring team found in a pool last year, plus three different species of juvenile salamanders under some wood in the park two weeks or so ago.

In the Woods, Not Much Drama, but Burgeoning Life

Again this year, a raccoon is inhabiting the giant hole in the Oak-Hickory forest. Other years this has meant a passel of playful kits by the end of May. I saw nothing until I stepped into the crunchy leaves at the trail’s edge and this curious face popped up at the edge of hole.

A raccoon has found the hole that is often used by females to bear and raise their young. We’ll know by the end of May.

The Red Admiral Butterfly (Vanessa atalanta), a migrating insect who probably overwintered in southern Texas, arrived at the wood’s edge a couple of weeks ago. According to Wikipedia, Red Admirals usually have two broods here between May and October.

The Red Admiral overwinters in Texas but comes here to have 2 broods between May and October.

Under the growing canopy of bright new leaves, a carpet of Wild Geranium (Geranium maculatum) is blooming. In the blossom below, a tiny bee from the Halictadae family has curled up to feed on flower nectar. These tiny bees are commonly known as “sweat bees” because they like to lick salt from us humans (luckily, their sting is very minor). This bee’s bright metallic green may mean it’s an Augochlora Sweat Bee (Augochlora pura), solitary bees who don’t live socially in hives. If you know your Michigan bees, please feel free to correct me.

 The Little Dramas Keep Life Coming

The dramas of spring creatures mean life continues. The best singer, the most beautiful feathers, the best provider of a good territory get chosen and a new generation begins. Fortunately, the temporary territorial disputes of birds don’t usually result in death or destruction. One bird moves on to new territory and in many cases, joins his former competitor in a fall flock which ends up feeding calmly together on winter feeding grounds. Nature knows that both low level conflict and general cooperation keep life going, even improving, generation by generation.  Maybe we humans should take a lesson from them?

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

Ox-eye Daisies CL

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

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

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

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

Singing House Wren

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

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

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

Out in the Old Fields: Fancy Bugs!

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

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

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

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

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

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

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

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

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

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

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

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

Creatures that Favor Moisture and Shade

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

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

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

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

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

 Berries in the Shade

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

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

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

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

Insects that Have It “Made in the Shade”

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

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

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

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

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

A Park for All Seasons

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

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

THIS WEEK AT BEAR CREEK: Spring Bursts into Summer – and Delicate Paint Creek Trail Surprises

Geraniums in the woods BC
A carpet of Wild Geranium in the Oak-Hickory forest

Well, what a change! Two weeks ago, we had spring flowers, leaf buds and spring courtship as birds sang and showed off in the treetops. And then came the heat and sun, and suddenly, it was early summer with leaves seeming to enlarge by the hour, spring flowers disappearing to be replaced by early summer blooms, more baby birds and the first dragonflies swooping along the paths in front of us.

Blog post and photos by Cam Mannino

So let’s explore just a few of the  wildflowers and creatures that shared this change with us.  (Plus some lovely post-prescribed burn surprises along the Paint Creek Trail.)

When it was still spring…

 Late Spring Birds and a Fun Insect

The male Rose-breasted Grosbeak’s  (Pheucticus ludovicianus) long, tuneful song was everywhere in Bear Creek in the last weeks of spring. Now their nests are finished and singing  has to accompany the task of raising young. Both the male and female build that nest and care for the young – a very modern couple! (Click on photos to enlarge; hover cursor for captions.)

Nearby, hopping from limb to limb, two male Yellow Warblers (Setophaga petechia) sang their seductive “Sweet, sweet, I’m a little sweet” song as they chased each other through the small trees at the edge of the woods. I never spotted the female, though she must have been nearby.  She lacks the rusty striping of the male and has a more olive back.

In the fields behind the Playground Pond, a pair of Eastern Towhees (Pipilo erythrophthalmus) were getting acquainted. The male was not singing his “Drink your Tea-a-a-a-” call, so I think the two may have been looking for a nesting sight. I’d never seen the female Towhee before and she’s quite different from the male’s coloring.

Speaking of nesting, I found this large egg under one of the walnut trees near the lane.  If one end hadn’t been missing, it would have been about 2 1/2 inches long.  And there was nothing inside.  I’m wondering if it could be the shell from the egg of a Red-tailed Hawk (Buteo jamaicensis) that I’ve seen off and on near the Center Pond. Cornell Lab describes the Red-tail’s eggs as 2.2 to 2.7 inches long and “white or buffy, blotched or speckled with buff, brown, or purple.”  What do you think?  Any bird egg experts out there?

Red-tailed Hawk egg?
What could be the hatched egg of a Red-tailed Hawk – but I can’t be sure.

A flash of iridescent green  at my feet signaled the hyper presence of the Six-spotted Tiger Beetle (Cicindela sexguttata) who frequents the forest edge. I imagine it got its name because its larva, developing in a burrow during the summer, springs up out of its hole to catch prey!  A tiny, green, stalking tiger! Cool how their antennae and legs are as green as their bodies.

Late Spring Wildflowers and Leaves

Two weeks ago, the Oak-Hickory forest was filled with big, beautiful Wild Geraniums (Geranium maculatum). These lovely lavender flowers carpet the area near the marsh every year, but this year they were all over the park –  taller, more plentiful and with larger blooms than I’ve ever seen! Perhaps this year’s and last year’s prescribed burns helped.

Wild Geranium
Wild Geranium blossoms bloomed in the mottled spring light of the forest.

Each year I wait for the blossoming of the Flowering Dogwood (Cornus florida) that stands east of the Northern Loop.  I was intrigued to learn that the actual flowers are only the center of these blossoms.  The “petals” are actually bracts, specialized leaves that attract pollinators by glamorizing the cluster of tiny center flowers.  Here are three pictures of the buds, encased in their bracts,  opening as May progresses.

While the Flowering Dogwood buds were opening, the leaves of the Shagbark Hickory(Carya ovata) were just emerging from their amazing buds.

The huge White Oaks (Quercus alba) near Snell Road were producing miniature red leaves  that, two weeks later, were green and stretching out to catch the sunlight.

White Oak leaves are red when they first emerge, but quickly expand and turn green.

Of course, the May Apples (Podophyllum peltatum) were producing their modest white flowers that hang hidden beneath an umbrella of leaves.

Another spring favorite of mine are the little hands of Early Meadow-rue (Thalictrum dioicum) that find spots of sun in the mottled spring light of the woods.

Down at the pond, tiny aquatic buttercups, called White Water Crowfoot  (Ranunculus longirostris) floated in large swirls across the pond.  Once the heat arrived, the flowers disappeared and the brown stems are now making a not-so-lovely brown mat until they sink below the surface.

Heat! And Summer Rushes Forward

Summer Birds and other Creatures

Green Heron (Butorides virescens), one of our summer residents, perched in a snag (standing dead tree) at the Center Pond.  I usually see them fishing at the water’s edge.  According to Cornell Lab, “The Green Heron is one of the world’s few tool-using bird species. It creates fishing lures with bread crusts, insects, earthworms, twigs, feathers, and other objects, dropping them on the surface of the water to entice small fish.”  I will be watching now to see if I can catch one doing that!

Out in Bear Creek Marsh, Ben and an experienced birder, Antonio Xeira, heard the call of a seldom-seen denizen of wetlands, the Sora (Porzana carolina). This waterbird, a member of the Rail family,  with a heavy yellow beak and stock body,  stalks quietly among the cattails, looking for seeds, insects and snails. Its whinnying call is particularly dramatic. Ben and Antonio recognized its other two tone “ker-wee” call at the marsh. Click on its picture here and go halfway down this page for its song and call. I’d never even heard of Sora before!

A delightful sight greeted the Wednesday birders at the Playground Pond last week. A mother Wood Duck (Aix sponsa) was escorting her six ducklings around the pond,  as well as what appeared to be two Hooded Merganser chicks (Lophodytes cucullatus)! Ben surmised that perhaps a Merganser had laid its eggs in the nest hole of the Wood Duck and she ended up hatching them along with her own. Here’s a photo of the adult female with her own chicks and a photo of a Hooded Merganser baby that swam with them.  This Merganser duckling jumps from a tree hole when one day old and swims on its own.  It takes 3 days for the Wood Duck’s ducklings to do the same.

Down at the Center Pond, the “boing-boing” banjo sound of the Green Frog (Lithobates clamitans) creates part of the summer music at Bear Creek.  You can tell this one’s a male because its tympanum, a kind of external ear drum, is larger than its eye. I like this one’s tentative expression.

And the Common White-tail Dragonfly (Plathemis lydia) makes a soft whir-r-r as it soars by, looking for prey. This one’s a female, because the male’s abdomen is white, which accounts for its common name.

Summer Wildflowers

As the heat began, wildflowers started to bloom in the native beds near the parking lot.  One of the loveliest is native Wild Lupine (Lupinus perennis) glowing lavender and white in the warm sunlight.

Nearby was a plant I’d never seen until Ben VanderWeide, our stewardship manager,  made me aware of it.  It has the lovely name of Blue-eyed Grass (Sisyrinchium angustifolium).  To me each tiny blossom resembles a tiny Iris.  It’s called “grass” because it has grass-like leaves and stems with parallel veins that are hard to distinguish from a grass when there aren’t any flowers. The flowers only open fully in full sunlight, so it can be easy to miss early in the morning or on a cloudy day. But isn’t it pretty in the late spring/early summer?

And another early summer favorite is spreading abundantly in the native bed north of the shed.  Canada Anemone’s (Anemone canadensis) lovely white flowers stand gracefully above its deep green foliage .

Sunny Golden Alexanders (Zizia aurea) accompany these other native plants in the wild garden in the driveway center, one of the native beds and across from the Playground Pond.  This one’s hosting a Spittle Bug or Frog Hopper, common names for the super-family of insects called  Cercopoidea.  The adult insects can hop 100 times their length!  The foam is used for protection for the nymph stage of development.  Though the nymph sucks on the plant, it generally doesn’t hurt the plant much.  Most of the liquid is used to create that evidently nasty-tasting froth that deters predators.

Ben and his crew planted some native Prairie Phlox across from the Playground Pond, another area of Bear Creek to be slowly stocked with native plants.

Warm weather brought out the exotic-looking blooms of native Wild Columbine in the bed just north of the shed.  These lovely native wildflowers grew down the side of a hill east of the park when it was a farm back in the 1930s and 40s.

Native Wild Columbine once grew on a hillside east of the park when Bear Creek was a farm in the 1940’s.

And out in the eastern Old Field, lots of native Common Milkweed appeared once the grasses were knocked back by the prescribed burn in March.  No doubt all the nutrients that were released into the soil then, plus the longer growing season caused by the darkened earth, will give it a little boost.  Hope the Monarch Butterflies take note!

Milkweed plants take advantage of increased sun and nutrients since the prescribed burn.

And now the Paint Creek Trail surprise…

This spring, Ben VanderWeide, the Township Stewardship Manager, and volunteers did a prescribed burn along the Paint Creek Trail near the parking lot at Gallagher Road.  The purpose, as always, was to stimulate native plants and discourage non-native invasive ones.  Also prescribed fire releases nutrients from last year’s plants back into the soil.

Partly as result of this process, some lovely native plants emerged this year in greater numbers than before the burn.  Look at this lovely photo Ben took of a native Yellow Ladyslipper  orchid (Cypripedium parviflorum)  – and there were lots of them hidden within the burgeoning grass. You can certainly see where this lovely wildflower got its name – a graceful slipper with ribbons attached!

The grass was also shining with Star-grass (Hypoxis hirsuta), a small yellow native that hosts small bees and other pollinators.  It’s lucky there were lots of these shining stars this year because they need other plants to cross pollinate, which of course is assisted by the bees.  Here’s Ben’s photo.

These bright yellow flowers called Star-grass also shone out of the grass along the PC Trail after the prescribed burn.

Along the tree line near the parking lot at Gallagher, a yellow cloud of Golden Alexanders (Zizia aurea) nodded in the wind.  Ben caught this one up close.

And Ben also noted a Sedge plant  (family Cyperaceae)  with its interesting bloom. As I mentioned two weeks ago, sedges are ancient plants that look something like grasses but are constructed differently. Ancient Egyptians used sedges to make papyrus.

Ben tells me that beautiful native wildflowers like Culver’s Root (Veronicastrum virginicum), Showy Tick-trefoil (Desmodium canadense) and other prairie plants are “sprouting vigorously” along the trail north Gallagher Road – so click on the links to see them and then keep an eye out for them!

So treat yourself.  Hang some binoculars around your neck and look at birds up close – both the year ’round residents and the summer visitors.  Take your time.  Stand near a patch of summer flowers and watch quietly. See what surprises you.  Maybe a bee that turns out to be a harmless hover fly.  Or the shiny glamour of the Six-spotted Tiger Beetle.  Try using your cell phone to take a shot of a single flower you’ve never noticed before and then identify it when you get home.  I promise you’ll relax.  Your breath will slow, you’ll smile a bit more, life will just get more interesting.  Nature comes alive in ways you’d never expect when you give it your undivided attention.  Let us know what you find!

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.

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
A colorful male Chestnut-sided Warbler at Cranberry Lake Park

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.

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: Small Creatures with Great Gifts

It pays to look carefully as you stroll along the paths of Bear Creek. Small creatures are sometimes the most amazing.

Blog post and photos by Cam Mannino

scarlet tanager2
The Scarlet Tanager fresh from his trip from the west coast of South America

Though a friend on Gunn Road tells me she sees them in the woods behind her house, I’ve only seen the Scarlet Tanager (Piranga olivacea) once in Bear Creek, near the northern entrance to the marsh –  but it was worth waiting for! Fresh from the northwestern edge of South America, they move high in the trees and are usually difficult to see, the female especially as she’s olive above, yellow below, matching the spring leaves. This one’s special talent is just being gorgeous!  Keep a sharp eye out and let me know if you see one!

wren - Version 3
The House Wren’s song is the essence of spring

The House Wren  (Troglodytes aedon) makes Oakland Township part of its huge range; this small vocalist sings for folks  from Northern Canada to the tip of South America.  Cornell Lab says this tiny bird weighs about the same as two quarters. Despite its small size the house wren competes fiercely with bigger birds for a preferred spot, sometimes evicting others from nests they are already using. But they also accommodate themselves to mailboxes, old boots, wren birdhouses or any nook or cranny.  Look for “Typical Voice” on the left of this link to hear his famous song:

Here’s another wee beauty , the Yellow Warbler (Setophaga petechia), a summer visitor to Oakland Township that Ben saw in the park last week.

yellow warbler2
The male yellow warbler sings “Sweet, sweet, I’m a little sweet.”

This tiny bird  sings a great little song that birders often hear as “Sweet, sweet, I’m a little sweet.” That’s how I spotted this little male. Yellow warblers like wet places so look for this little guy near the center pond or listen for him in the bushes near the marsh.  Here’s a link to his song.  See what you think he’s saying. We’ll discuss Brown-Headed Cowbirds (Molothrus ater) another time, but they lay their eggs in other birds’ nests, particularly smaller birds like the Yellow Warbler.  Even if the warbler recognizes the interloper egg in its nest, the bird’s too small to push the egg out, so it usually just builds a nest on top of the original one, lays its eggs and ignores the cowbird’s. Pretty nifty solution, though it’s a good thing bird’s don’t have much sense of smell, eh?  I’ve never seen such a nest, but I’d love to!

American Goldfinches  (Spinus tristis)  live with us all year, though there may be some slight shift in populations from north to south during the winter.  The bright yellow of the males is a sure sign of spring, and during the Goldfinches’ second molt in late fall, the male’s return to the olive-yellow of the female presages the coming of winter. Goldfinches, one of the strictest vegetarians of the bird world, eat only seeds unless a hapless bug happens to fly into their beak during flight! While other birds are busy courting in the spring, they establish territories and wait to breed until late summer when the thistle seed they love is plentiful.  They make tiny nests (3″ across x 2.5″ high) woven together with spider silk and lined with thistle down.  Sounds pretty cozy.  Here’s a link to their cheerful song. This finch pair (note the different plumage) seems to have had a tiff: finch1

Ah, and then  buzz, whirr,  click, the Ruby-Throated Hummingbird (Archilochus colubris) zooms into the park during the first two weeks of May.

hummer in the rain2
A rainy day dims the dazzling colors of the Ruby-Throated Hummingbird.

Though this photo taken in the rain dims him a bit, in bright sunlight the sparkling iridescence of the male’s green head and deep ruby throat dazzles the eye and his ability to fly in any direction, even backwards, beating his wings 53 times/second is really impressive. He weighs only 1/10th of an ounce and has to eat 50 times his weight in nectar daily! The plainer green females arrive later, build their half dollar-sized nests and do all the care and feeding of the young. Hummingbirds are not common in Bear Creek but Ben saw one last week, actually sitting quietly like my rainy day one.

water strider
Water striders have the unique gift of walking on water

Speaking of small talented critters, look closely at the surface of calm water anywhere in the park right now and you will see Water Striders (Gerridae). They are unique in the insect world for their ability to walk on water!  Their specially adapted legs are covered with thousands of hairs that repel water, help them distribute their weight and trap air to bring the strider to the surface if dunked. The middle legs row and the back legs steer and they can really scoot across the water!

6 spotted tiger beetle
The Six-spotted Tiger Beetle flits along the boundary between the forest and the sunlight.

One more interesting little insect, the Six-Spotted Tiger Beetle (Cicindela sexguttata), flits along paths near the woods through the park now.  Probably his fierce name comes from the fact that the larvae burrow into the ground when they hatch where they lay in wait.  When a spider or insect happens by, they spring out and attack – much like a tiger pouncing on prey.  Someone with a fine imagination named this little guy!

violet
Michigan has 28 different varieties of violets

Our native Violets  peek out here and there.  Aren’t they lovely with the stripes on their petals and that beard at the center?  I think these are Common Blue Violets (Viola sororia) but don’t hold me to it, since there are 28 species of violets in Michigan, according to the University of Michigan Herbarium.

wild strawberry
Wild strawberries are plentiful in Bear Creek this year

The Wild Strawberries (Fragaria virginiana) are in full bloom and they are everywhere!  Just think, every one of those flowers is  a potential berry! A feast for wildlife since they’ll probably eat them all before they are ripe enough for humans!

May apple bud and blossom
The buds and flowers of the May Apples hide shyly below the leaves.

The May Apples (Podophyllum peltatum) are now producing their shy buds, those inedible “apples”after which they are named.  Some are blooming too,  in their shy way, bowing humbly beneath the leaves. Here are a bud and a blossom.

IMGP4489
Wild Geraniums are blooming in many more places after the prescribed burn.

Reliable sources (Ben and my husband Reg) tell me the carpet of Wild Geranium (Geranium maculatum) has finally arrived and indeed is even more beautiful after the prescribed burn!  Geraniums are blooming in areas we’ve never seen them before!  Here’s Ben’s photo from Monday, the 18th.

Red squirrel closeup
The American Red Squirrel will chatter at you as you emerge from the woods at the Snell entrance.

And just to give small talented mammals some due, the American Red Squirrel (Tamiasciurus hudsonicus) occasionally leaves a legacy to its offspring!  You’ll hear these squirrels, the smallest in the park, chattering at you as you emerge from the trees on the path from the Snell parking lot. They are very intense about their territory and you are passing through it, for heaven’s sake! They are feisty, speedy and spend part of every day creating middens, places where they store seeds and other goodies. If food is scarce, females will evidently “bequeath” one to their young, that is, give up the midden and part of her territory to her offspring. Nice little inheritance!

Coming Attractions:

wood duck and 6 ducklings
The amazing Wood Duck’s ducklings will arrive in June.

Watch for the somewhat elusive Wood Ducks (Aix sponsa)! They are in the park now, but by mid-June, there will be ducklings! And what ducklings they are! Wood ducks nest in holes in trees as tall as 60 feet. When the ducklings are two days old, mom leaves the nest, flies down to the water and calls her young.  One by one they screw their courage to the sticking point and launch themselves into the air. Their wings are too small for flight,  but they are so light they bounce on the leaf litter below. Once they are all out of the nest, they go to mom and begin to swim. Now that’s quite a gift. For a one minute video of this feat, check out this link from the PBS program, Nature. It’s just wonderful, truly. Here’s a female and a couple of ducklings in the center pond at a bit of a distance last June.

And watch for the dragonflies and damsel flies! They are just beginning to swoop and dive around the ponds and in sunny spots near the woods,  but there will be all kinds of them as June and July come on.

Quick Review:  Spotted Again this Week!

  • One Snapping Turtle in the pond near the playground, and 3 in the marsh on Sunday the 17th!

Three snappers were seen in the marsh last week.

 

  • Rose-Breasted Grosbeak (Pheucticus ludovicianus) singing in the trees near the northern entrance to the marsh also on Sunday.
