Photos of the Week: A Rookery Full of Great Blue Heron Fledglings

At a rookery along the Clinton River Trail west of Dequindre Road, young Great Blue Herons (Ardea herodias) are preparing to go out on their own. According to the Stokes Guide to Bird Behavior Volume III, both adults care for the eggs for 28 days, and the nestling phase lasts 7-8 weeks. Now, in mid-July, the young are fully fledged but still at the nest practicing their wing techniques. Their hard working parents will feed them for another 2 or 3 weeks, and the young herons will take their first flights during this time.

According to both Stokes and the Cornell Lab of Ornithology, the young can be identified by two-toned beaks (rather than all yellow), black and white striped necks (rather than solid color),  and a solid black crown (rather than the black and white adult crown). So I’m guessing that all the herons you’ll see below are fledglings. In the slide show below, a young heron tries out different wing movements, perhaps to build up necessary muscles or just get the feel for different positions – arched high, extended flat,  curved forward for slowing down to a stop, etc.  One youngster also seemed to practice spearing with its huge beak, striking down into the edge of the huge nest of twigs.

It’s important to be very quiet and unobtrusive around heron rookeries. The birds are easily disturbed and can abandon rookeries where there’s too much activity and noise. Luckily this one is protected from the busy trail by a scrim of trees. So if we’re quiet, careful and stay on the trail, the herons can continue to ignore hikers, bikers and the occasional curious amateur photographer sticking her camera between the leaves!

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

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

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

Industrious Parent Birds and Their Demanding Offspring!

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

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

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

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

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

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

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

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

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

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

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

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

An Unusual Sighting

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

Butterflies Big and Very Small

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

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

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

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

The Red Admiral butterfly migrates from the south each spring.

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

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

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

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

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

Flowers Blooming at Draper Now that are New to Me

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

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

 

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

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

Turtles vs. Creatures That Love Their Eggs

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

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

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

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

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

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

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

Photos of the Week: The Monarch Butterfly Caterpillar and its Host

Along the Paint Creek Trail,  Butterfly Milkweed (Asclepias tuberosa) foliage and flowers are hosting small native creatures –  a Bumblebee (genus Bombus), a Harvester (order Opiliones) – and those glamorous larvae –  Monarch Butterfly Caterpillars (Danaus plexippus).  The Monarch butterflies lay their tiny eggs on the underside of milkweed leaves. 3-8 days later, the larvae, or caterpillars, emerge and feed on the plant. The caterpillars go through 5 molts until the 5th instar attaches itself to a horizontal surface using a silk pad and forms a chrysalis. Two weeks later they emerge transformed as adults, beautiful butterflies.

That’s the beauty of native plants; they’re the natural host for the creatures with which they “grew up” or evolved – like the native bumblebee or the harvester, an outdoor arachnid that’s a distant relative to the spider.   Native creatures in turn pollinate other native flowers or provide forage for native birds, amphibians and reptiles. Native plants form the foundation for preserving our native habitat – and beautiful creatures like the Monarch butterfly!

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.

A Little Wood Satyr butterfly rests in the shade

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.)

Photo of the Week: The Return of the Hairy Beardtongue!

 

This slideshow requires JavaScript.

A downy, native wildflower is staging a comeback along the Paint Creek Trail south of Gunn Road. Two years ago, the Oakland Township Parks Stewardship and Maintenance crews partnered to eliminate invasive shrubs along the hillside there. Ben noticed native flowers and grasses and hoped it was a likely spot for restoration.  And it was!

This year a large patch of Hairy Beardtongue (Penstemon hirsutus) emerged as sunlight finally reached the soil disturbed after the shrub removal.  This species is adapted to fire and disturbance. They no doubt thrived along the trail when train sparks caused periodic fires along the tracks. So when Ben created the right conditions, the Beardtongue seeds, which had waited patiently in the over-shadowed seed bank for years, made their move. Now bumblebees probe the blossoms with their long tongues, feeding on the nectar and dusting themselves with pollen. So maybe even more of these fuzzy blooms will nod their lavender heads along the trail next year!

 

Bear Creek Nature Park: Little Spring Dramas Everywhere You Look

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 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

Delicate early spring blossoms of the native Serviceberry (Amelanchier interior) near the eastern end of the Center Pond

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?

Photo of the Week: A Rare, Beautiful and Frilly Sight: Meet the Bogbean!

 

This slideshow requires JavaScript.

In a watery hollow within Bald Mountain State Recreation Area, bloom a huge number of unusual and elegant native plants with the mundane name, Bogbean (Menyanthes trifoliata).  Along each plant’s petals, fine white hairs create a frilly effect.  Why frills?  I couldn’t find much information, except for one Finnish website that thought they probably defended the flower’s nectar from small insects that weren’t much help in pollination.  Bees, especially bumblebees, are attracted to these lovely flowers which also spread through rhizomes (underground stems) in shallow water or on the muddy shore.  This hollow is a “kettle” which was created by the melting of  a huge chunk of glacial ice. What a sight to come upon in the forest – a bed of white shining in the sun beneath a huge gap in the tree canopy!

Photo of the Week: A Fierce Predator Goes Courting

A Red-tailed Hawk scouting for prey near Lost Lake Nature Park

Now is the time to watch for the courtship of Red-tailed Hawks (Buteo jamaicensis). High in the sky, the pair soars in wide circles close to one another. Sometimes the male will dive steeply downward and then swoop sharply back up. Occasionally, he drops toward the female from above and touches her with his talons.  If you’re lucky, you may even see them clutching each other and tumbling through the air until they fly off together.  Quite an aerobatic courtship!

BEAR CREEK: Is It Spring Yet? Ummm, No… plus Tracking Bear Creek Itself

What a crazy February and March, eh?  Snow, ice – and then suddenly mud, warm sunlight, even a butterfly! – then icy winds again.  Such schizophrenic weather complicates life in the natural world.  A snake basks in the sun one day and a few days later, returning sandhill cranes peck along the surface of thin ice.  Ducks leave wing prints and webbed feet tracks on a snowy pond and a few days later, a female crayfish emerges with eggs under her tail.  Never a dull moment in the parks! Meanwhile I set off to track the meandering course of Bear Creek itself.

 

Early February – A Normal Winter for the Birds

Robin in evening sun BC
A Robin plumps against the cold on an early February day

American Robins (Turdus migratorius), despite their association with spring, know how to cope with cold days:  find dried fruits on old vines, turn your dark red breast to any sunlight available and plump up your feathers to create some down insulation.

The Tufted Titmouse (Baeolophus bicolor) on the western slope found sun at the very top of a tree and decided to try out his mating call on an icy morning.  “Peter, Peter, Peter,”  he trilled,  despite the snow below.

A small flock of Eastern Bluebirds (Sialia sialis) passed contact calls back and forth in the small trees and shrubs.  The male  below probably spent this odd winter at Bear Creek and appears to be just fine.

A male Eastern Bluebird pauses on the branch of a small tree

Nearby, a small bird busily wound its way up a tree, poking at the bark every few seconds and moving on.  That upward spiral was a clue.  It was a Brown Creeper (Certhia americana), a funny little bird with a small head and a long sharp beak good for winkling out bugs and larvae from tree bark.  If you look carefully in my hastily shot photo, you can see its right eye and curving black beak.

Brown Creeper 2 BC
A Brown Creeper always works its way around and up a tree when foraging.

The longer days brought a  warm weather migrant to the marsh, the Song Sparrow (Melospiza melodia). It probed the grassy clumps protruding from the ice, looking for tidbits – seeds, perhaps?  This  sparrow’s cheerful mating song will burble forth all over the park when real spring arrives.

Then, Suddenly, Spring, Off and On

Residents take immediate advantage of a spring-like day at Bear Creek.

Somewhere near the middle of February  the temperature rose, the ice began to melt, and the snow turned to mud. Humans, that most adaptable of creatures,  came out to enjoy a respite from winter cold. And so did some other animals who may have been fooled into emerging a bit early!

This Eastern Comma Butterfly (Polygonia comma) probably spent the winter as an adult under the bark of a log or in a hollow tree. It’s common to see them alone in a sunny spot in early spring – but not usually in February!  I hope this one went back to its winter digs as the temperature dropped!

Eastern Comma Butterfly BC February
An Eastern Comma butterfly emerged from hibernation as the weather warmed unseasonably in February.

Further along, an Eastern Garter Snake  (Thamnophis sirtalis) basked in the sunlight on the trail before slipping off into the grass.

A basking Garter Snake slipped off the path into the grass.

On another warm-ish day, the birding group came upon 30-40 talkative year ’round residents, Cedar Waxwings (Bombycilla cedrorum), flitting from tree to tree and whistling in their thin, high voices. Cornell Lab recently posted that scientists are exploring the idea that the waxwings with the most red waxy dots on their wing tips are the most mature adult birds and the most likely to be successful at mating.

Flock of Cedar Waxwings BC
A flock of Cedar Waxwings whistled and flew from tree to tree in late February.

The birding group was greeted by the waving claws of a small, but assertive female crayfish sitting in a puddle on the trail near the pond. Under her tail, she carried quite a load of eggs.  Michigan has eight native species of crayfish, and one aggressive, invasive one, called the Rusty Crayfish.  This one could be the invasive because according to U-M’s Biokids site, they take an aggressive claws-up stance to fight off predators (as she did when we approached) and she also had smudge-like spots on the back of her carapace. But crayfish are  difficult creatures to positively identify, so for now,  we’ll just say she’s a crayfish.  If her eggs hatch despite the cold that returned the following day, she will carry her young through several molts, until they fall off and start life on their own.   Thanks to Ben for his great photo.

Canada Goose (Branta canadensis) floated above her reflection in the Center Pond.  Some of the birders wondered if it could be classified as the subspecies of Lesser Canada Goose, since its neck is shorter than most Canada Geese. But since its body and beak are large, it’s hard to say.  It may just be normal variation – or maybe it had a Lesser Goose  or Cackling Goose relative (Branta hutchinsii) in its past!

Lesser Canada Goose BC
This Canada Goose has a remarkably short neck so it could be part of a subspecies called the Lesser Canada Goose.

In the unseasonal warmth, a native Hazelnut  bush (Corylus americana) extended its long male catkins that will fertilize the tiny female flowers on the twigs when they emerge later.  The little flowers eventually produce clusters of nuts.  The farmer who lived on Bear Creek during the Depression and WWII gathered these nuts as a boy, as reported in an earlier blog.

These male catkins of the Hazelnut bush will fertilize tiny female flowers on the branch to produce  – what else? – hazelnuts!

Winter Returns, Sigh…

The marsh froze over again – thinner ice that water birds could peck through to forage in the water below.  One morning in a cold wind, a pair of  Sandhill Cranes (Antigone canadensis) poked about on the ice near Gunn Road, stalking back and forth on their knobby legs.  They didn’t seem to be finding much to eat.

Sandhill Cranes poked at the thin ice when the marsh re-froze after the false spring.

At the Center Pond, it looked as though some ducks had walked on the ice and then taken off, leaving some decorative webbed foot tracks and wing prints in the snow.

The next morning, the sun broke through and thinned the ice. A male Canada Goose found a break in it and stuck his head down, looking for food. Brrr…glad they have plenty of fat and keep their layers of feathers well-oiled  by preening from an oil gland at the tip of their tail like other water birds.

On the western slope, a male Eastern Bluebird repeatedly swooped down into the grass and back up into a nearby bush, evidently finding some seed he liked on a cold morning.

And along the upper part of the Walnut Lane, tracks revealed the path of what might have been a Coyote (Canis latrans) from the size of these canid tracks.  Like the fox, when they trot, they place the back foot where the front was – hence the single tracks.  Wish I could see this animal in the park.  Its scat is everywhere!  We can be assured, I think, that this animal does just fine no matter what the weather!

 Tracking the Meandering Path of Bear Creek Itself

Occasionally a park visitor asks me why the park is called Bear Creek.  Well, I don’t know why the creek was called “bear” because there are no bears.  At one time, the marsh was reportedly called “Bare Marsh” because of the many dead trees standing in the water years ago.   But some people ask because they haven’t noticed the little creek  and its meandering path that eventually reaches Paint Creek.  I never paid  much attention to it myself once it left the Center Pond boardwalk.  But in February, I decided to follow it.

It begins, I believe, in a spring that I saw  years ago during a drought that dried up the pond.  All that was left was a wet spot at the west end of the pond,  with water seeping eastward in a feeble stream.  In a normal year, when the water is high, a small creek flows out  under the boardwalk at the pond’s eastern end.

bear-creek-begins-out-of-center-pond-bc

From there, it runs east through the woods, enters Bear Marsh and picks up ground water. In the photo below, it exits the marsh running north out of  the culvert under Gunn Road.

The little creek then takes a left hand turn, flowing back west.  In the woods somewhere, it evidently takes another left, bending south until it crosses under Gunn Road again right across from Pine Needle Trail, near Collins Road.

Bear Creek at Pine Needle Trail off Gunn BC

It wends it way south behind various houses, appearing again at a culvert under the aptly named, Bear Creek Court off Collins Road.

Just north of Oak Hill , near the entrance to the Township Hall,  the creek crosses under Collins Road.

Bear Creek going under Collins Road BC

 

It flows  along a ditch on the western side of Collins Road and curves behind the Paint Creek Methodist Church and the Lyon Gear factory,

At that point, the creek takes a dive under ground, crossing Orion Road and appearing again at what appears to be its final destination, flowing out of a culvert as it joins Paint Creek behind the Cider Mill parking lot.

Bear Creek empties into Paint Creekk at Cider Mill

A Creek with a Past Flows Toward Its Future

It’s wonderful to think of the hundreds, perhaps thousands of spring mornings during which this little creek has wended its way from a modest pond in a field off Snell Road to merge at last with Paint Creek.  Long may it meander across the landscape.  If we are careful stewards of the natural beauty granted to us, then for generations to come, the bluebirds will still forage in the meadows on azure wings, the coyotes will still trot up the lane on a winter night, and the butterflies will still slip out of tree bark into the sunshine. My thanks to all of those whose efforts and resources make that future possible!

Draper Twin Lake Park: Dashes of Color and Ice Artistry Livened Up the January Thaw

Skaters just before the January thaw started at Draper Lake
Skaters just before the January thaw started at Draper Lake

Snow, ice, sleet, rain – all the elements of Michigan’s traditional “January thaw.” Sigh…Gray skies day after day make me crave color! On multiple jaunts at Draper Twin Lake Park  – some icy, some muddy – I sought it out.

As usual, the mushrooms provided a surprising splash of color here and there. Birds in varying shades of red relieved winter’s gray. And changing ice designs added a bit of artistry to every visit. Hey, we take what we can get in beauty at this time of year, right?

Along the Path to the Eastern Marsh:  Red Birds, Yellow Mushrooms and Blue Shadows

A Red-bellied Woodpecker (Melanerpes carolinus) drummed noisily on a telephone pole on the eastern side of the park. Let’s hope this male had a cozy hole to spend the  winter night; the starlings, twittering in a thicket nearby, are known for absconding with holes created by Red-Bellies. This guy’s red cap glowed against a gray sky – a good omen for someone questing for color on a dark day!

On the way to the marsh, a chorus of House Finches (Haemorhous mexicanus) chirped from the shrubbery. These gregarious birds with their rosy males added both color and the friendly sound of their “chatting” to the gray quiet. House Finches pause to busily crush the seeds they find with quick bites, making them easier to spot and photograph.

house-finches-4
A group of House Finches chirped among the shrubs on the path to the marsh on Draper’s east end.

A male Northern Cardinal (Cardinalis cardinalis) added a gorgeous dash of scarlet as he darted among the shrubs along the marsh edge at the bottom of the trail.

The scarlet of a male Cardinal offers a welcome break from gray on a winter’s day.

While at the marsh, I was surprised to hear what I think was the call of a Northern Flicker (Colaptes auratus) in the distance. The birders saw one at Charles Ilsley Park the previous week but I’ve never seen one in the middle of winter. If you listen to the “Rolling rattle call” at this Cornell Lab link, you’ll hear what I heard far away on a wintry day. Here’s a flicker I saw in early spring last year.

A Northern Flicker could be heard in Draper Park last week, but I never saw it. This photo is from the previous spring.

Out on the ice, a graceful swoop of marsh sedges turned blue and silver in the shadows.

The sedges in the marsh seemed tinged with blue in the shadows of a winter afternoon.

On a log near the marsh, a bright patch of yellow polypore/shelf mushrooms glowed under the edge of a log.  One of the reasons I love wetlands is that summer and winter,  they reward any hiker with colorful birds and mushrooms.

Out on Draper’s Northern Prairie

The Prairie Restoration on the northeastern part of the park looked very different than it did when the trees glowed with autumn color. (Click on images to enlarge; hover cursor for captions.)

But birds were there too. Flocks of modestly dressed winter visitors – Dark-Eyed Juncos (Junco hyemalis) and American Tree Sparrows (Spizelloides arborea) – hopped down from small bare trees and bushes, chattering away as they foraged on the ground.

That bit of leaf in the Junco’s beak may be result of flipping things over to look for seeds. The seeds of two native wildflowers left in the field looked as though they may have provided some sustenance. The seed pod of Wild Senna (Senna hebecarpa) on the left below and the dried inflorescence of a late-flowering Black-eyed Susan (Rudbeckia hirta) on the right are both native plants sown in 2015 by Ben VanderWeide, our Stewardship Manager, to restore the prairie, using a grant from the Fish and Wildlife Service.

Over the crest of a slope on the rolling prairie, a slow, lumbering Possum (Didelphis virginiana) nosed its way along the edge of the field. It appeared to be searching for seeds or earthworms on the wet earth exposed by the thaw. Possums don’t hibernate and are generally nocturnal, but there it was in morning light. Possums feign death (“playing possum”) when extremely frightened – but they’ll fight first –  so be wary of their sharp teeth. North America’s only marsupial, possums raise their infants in the female’s pouch for about two and a half months. Later, the babies, up to 13 of them, can be seen draped over their mother’s back as she goes about her business.

In a tree at the edge of the prairie one morning, a lone Mourning Dove (Zenaida macroura) blended its soft pinks with the gentle shades of the winter landscape.

Along the Western Path to Draper Lake

The western path was a bright glare of ice on my first January trip to the pond. At the edge of the parking lot, a dead branch still sported orange polypore/shelf mushrooms, just as it did  in the fall.  Amazing how hardy these fungi are in cold weather!

Orange Polypore Mushrooms Closeup Draper
The orange polypore (“shelf”) mushrooms survived the cold intact, perhaps even getting a bit more orange!

 

A stick covered in a mosaic of green and blue lichen and a nearby patch of leafy (foliose) lichen caught my eye.  Lichen are intriguing, because they are a “composite organism” made up of algae and/or cyanobacteria living among filaments of a fungus in a symbiotic relationship. The fungus provides protection for the algae and gathers moisture and nutrients.  The algae uses those nutrients and energy from the sun, and through photosynthesis produces food (carbohydrates) for both itself and the fungus. These ancient organisms occur from alpine regions to sea level in all kinds of shapes (morphologies). The more delicate forms of lichens are very sensitive to air pollution (bio-indicators), which is why you will only find flatter forms that colonize rocks and branches in areas with more air pollution. In areas with cleaner air you’ll find more delicate, branching lichens. I’m just glad they gave me some varying shades of  green and blue on a wintry day.

Near the pond during a bird walk, a bright yellow mushroom beckoned in the distance. How’s this for a bit of sunshine on a moist winter morning? I’m no expert at mushrooms, as readers know. To me, it looks like kernels of corn. But I think this one’s common name is “Witches’ Butter,” Dacrymyces palmata (Fungi get more imaginative names than plants do…). Any mycologists out there who can verify that for me?

yellow-mushroom-2
What may be “Witches Butter” mushrooms on a log near Draper Twin Lake

Lovely russet  patterns formed on the path, made  from White Pine needles (Pinus strobus) and a variety of leaves embedded in ice near the lake.

A strange ice sculpture took shape along the floating deck at the lake. I dubbed it the “Sunny Side Up” formation when I first saw it on an icy day. When I came back with the birders 10 days later, the surface ice had melted down, leaving the “yolk” standing in 3-D surrounded by icy ridges where the outline of the “egg white” once was. Wonder what created this interesting bulge in the ice?

Twice I came across ice fishermen out on the lake.  On the first visit, a man was unloading his sled full of equipment way off in the distance on the far side of the lake, while skaters glided about in the winter sunshine.

Three days after these skating scenes, the melt had begun and the rains came. The surface of the lake turned from white to gray, with inches of water standing on ice.

I saw (but didn’t photograph for some reason!) two fisherman walking out into that sloshing mess,  confident about the ice underneath. A strange sight! It looked like two men walking on water!

The last day I visited the park with the birders, the ice had developed a crackled surface. Quite a wonderful abstract design, but not one that would encourage venturing out onto the ice!

Later that week as the snow began to fall again, a Tufted Titmouse paused for a few moments in a nearby bush. One of these little birds fooled the experienced birders in our Wednesday bird group by seeming to mimic the “cheer” call of a Carolina Wren. According to the Sibley Guides website, Titmice have a wide variety of songs so maybe this is one of them.  Quite a performance, anyway.

Beauty Reveals Itself When We Seek for It

Ice Design Buell and Lk George
Ice design at Buell and Lake George Roads

On my way home from Draper Twin Lake Park one morning, I stopped to admire a “modern art” ice shape in a pond at the corner of Buell and Lake George Roads.  It could almost have been a composition by Matisse or maybe Paul Klee. For much of my life, I missed the details as I hiked through a landscape. The camera encouraged me to look more closely. Now nature gifts me with surprises – the quizzical tilt of a dragonfly’s head, the spiral of seeds in a flower head and this winter, odd ice designs and strokes of color within winter’s gray and white world.

But a camera isn’t necessary.  An observant pair of curious eyes is all we really need to notice the beauty that might otherwise be missed, especially in a January thaw.
