Bear Creek Nature Park: Snow, Sleet but Spring Arrived Anyway!

Red-winged Blackbirds in an April snow squall

Wow, what a tough April – for us and for wildlife! I even considered the possibility at one point that our thermometer was broken, since it seemed to be stuck at 32 degrees! The intrepid birding group went out in a snow squall the first week of the month. Despite cold and driving wind, we still came across flocks of early migrators, like the Red-winged Blackbirds (Agelaius phoeniceus) pictured above,  along with more than 60 robins foraging in the meadows.

We got a couple of brief respites in which it was possible to imagine a normal spring day with birdsong, fragile leaves, turtles warming in the sun. Then it was back in the freezer. Wildlife and plant life coped with cold wind and sleet, soaked up whatever sun was available and waited for change. We humans harnessed the warmer days for stewardship projects. And then voilà, spring arrived (I hope) last weekend.

Experts tell us that bird migration depends more on the length of spring days, than it does on the temperature. As a result, our first summer-only birds arrived to find snowy fields rather than the first greening of spring. What could they or our year ’round residents do but cope?

This Canada Goose (Branta canadensis) hid among the grasses at the edge of the marsh as the snow fell on the birders the first Wednesday in April. She’s probably been back for a few weeks and is well-equipped to deal with the cold. Normally by this time, though, she’d be picking nest sites, but I doubt this thin spot at the edge of the marsh was being seriously considered.

In a tree at the south end of the marsh, a male Northern Cardinal (Cardinalis cardinalis) looked dismayed by the cold wind ruffling his crest. His staring eyes seemed to suggest that he was as stunned by the freezing temperatures as the bundled-up birders below him!

Birders spotted the silhouette of a Turkey Vulture (Cathartes aura) hunched in a branch near the marsh. No doubt it was hoping to have some clean-up work soon. After all, its job and its food source is seeing that all the carrion in the park is dealt with quickly and efficiently. I had to wonder if it regretted having left southern Ohio, or points even farther south.

During a brief pause in the snowfall, a Common Grackle (Quiscalus quiscula), who may have spent his winter in southern Ohio, stared out into the white landscape. It’s likely he arrived with other males and a mixed flock of Red-wings and Brown-headed Cowbirds, frequent traveling companions this time of year.

Over at the Playground Pond, a shy little Eastern Phoebe (Sayornis phoebe) huddled on a branch, twitching its tail over the water, as the snow fell. Having perhaps wintered in Tennessee, this little bird is usually one of the earliest flycatchers to arrive in Michigan. So it’s hardy enough to brave the cold – though maybe, like us, it have would preferred better April weather. Look closely;  it’s nicely camouflaged against the branches and behind the veil of falling snow!

An Eastern Phoebe, in its brown and white plumage, almost disappears into the branches and the snowfall.

Our sturdy, native Pussy Willow (Salix discolor) survives even in Alaska and northern Canada. So it bravely thrust forth its fuzzy white catkins in the southern part of the marsh as the snow swirled around it. The bright, bare branches of native Red Twig/Red-Osier Dogwood (Cornus sericea) added a nice dash of color to a dark morning.

Some of the winter-only visitors are still stocking up before leaving for points north. Small flocks of  American Tree Sparrows (Spizelloides arborea) twitter among the bushes, getting last minute meals before heading to Hudson’s Bay or the Arctic tundra for the summer. They certainly seem to relish cold weather! I’m glad Bear Creek Nature Park seems to have provided enough winter food for this small long-distance flyer.

During a brief snow melt last week, the Dark-eyed Juncos (Junco hyemalis) also seemed busy preparing to depart northward for the summer. They foraged among the newly sprouting grass where the prescribed burn had taken place in March. They don’t travel quite as far as the Tree Sparrows, perhaps only into Ontario.

Short, Warm Respites Meant Birdsong, Frog Song, Turtles and More

For a few short days, off and on, we had sun and some genuinely spring-like temperatures. The  Wood Frogs (Rana sylvatica) thawed out from their winter freeze. The low, chuckling call of the Wood Frogs joined the constant, rhythmic peeping of the Chorus Frogs, featured in the blog a couple of weeks ago. Here’s a photo of a Wood Frog taken last November as they began hibernation. The black patch near the eye underlined with light yellow, plus ridges down the back are the field marks for this small frog.

Last November the Wood Frog found a spot to hibernate in a log or under fallen leaves.

The clucking or chuckling sounds in the foreground of this recording from a week ago are those of the Wood Frog. The higher-pitched calls in the background are from Western Chorus frogs. Be sure to turn up your volume!

On a cold but sunny afternoon, the male Song Sparrow (Melospiza melodia) chirped his burbling refrain as the wind ruffled his feathers and carried his melodious tune out across the Eastern Meadow.

A Song Sparrow lets the wind carry his song into the Eastern Meadow.

On the recording below taken ten days ago, he sings loudly twice with a bit of a rest in between.

When the temperature rose to sixty degrees, all kinds of plants, animals and insects seemed to come to life at once! When Ben ventured out into the park about 8:30 pm one evening, he heard the buzzing “peent” call of the American Woodcock (Scolopax minor).  This call from the ground precedes an aerial display in which the Woodcock spirals up into the sky and then chirps on the way down, plummeting the last several feet before landing right where it began. All this happens just before dark in small open fields near wetlands at Bear Creek and Cranberry Lake Parks. For the whole sequence of sounds during this mating flight, try this link at Cornell Ornithology Lab. (Wait for the “peent!” at the end. It will surprise you!). Though I’ve heard and briefly seen the Woodcock, here’s a photo by talented photographer Jerry Oldenettel at iNaturalist.org who’s had much better luck than I at getting a good photo!

The Woodcock probes for worms with that long beak and performs an elaborate courting dance as the sun sets.

A pair of Bluebirds (Sialis sialis) seem to searching out nest sites at Bear Creek. I saw a male one snowy afternoon peering down into the grass for possible food and a female surveying the Eastern Meadow.

This male Hairy Woodpecker (Picoides villosus) finds all kinds of good things to eat as he tap, tap, taps on a tree trunk. Though they’ll eat seeds and fruits, their preference is for insect larvae, so they’re very good stewards of trees, ridding them of bark beetles and other insects. According to Donald W. Stokes Guide to Bird Behavior (Vol.1), if we hear a quick, loud, regular beat in its drumming, that’s a mating call. When the drumming is lighter and irregular, the Hairy is either feeding or starting to excavate a nest hole.

The Hairy Woodpecker has a thicker, longer beak than the similar Downy.

Brown-headed Cowbirds (Molothrus ater) foraged in the fields as well. These handsome birds don’t create nests, but rather lay their eggs in the nests of other birds. Cowbirds aren’t really irresponsible parents. Having evolved to constantly follow western buffalo herds, they had no time to care for young. So the cowbirds who took advantage of the nests and care of other birds carried on the species!

The Painted Turtles (Chrysemys picta marginata), who’d been hibernating in the cold mud on pond bottoms all winter, climbed onto logs all over the park on the first warm day. In the photo below, nine of them were basking in a patch of  sunlight within a shady wetland, letting the sun soak into their dark shells. Aahhh, that must have felt sooo good!

While hand sowing native seed, we discovered Eastern Garter Snakes (Thamnophis sirtalis) twisted around each other in a wriggling hug as they mated in the brown grass. The female, according to Wikipedia, is larger than the male. They may have evolved this way because garter snakes bear live young. The more little snakes they can carry, the more likely their genes will go on to another generation.

With temperatures so low, insects are still scarce in the fields right now. But I noticed what appears to be a Sexton/Carrion Beetle (g. Nicrophorus, fam. Silphidae) clambering through grass and leaves one warm-ish afternoon. It was probably sensing a dead mouse or bird and heading to bury it as a source of food for its larvae. These small members of the “cleanup crew” are large and colorful, usually dark with red on the forewings and fancy club-shaped antennae.

I saw two plants making go of it in the cold April air. The perennial Skunk Cabbage (Symplocarpus foetidus) thrust it bulbous, purple bract (spathe) up through the mud. The bract envelops a long spike (spadix) which holds the flowers. Early flies and bees are attracted by its pungent (and skunk-y, not very pleasant) odor. Interesting that the leaves on this plant show up after the flowers.

At this time last year, another of the earliest spring flowers, Spring Beauties (Claytonia virginica) had already presented their pink- and white-striped blossoms in the forest. This year, though, in the middle of April, their spindly leaves were just starting up around the roots of large trees. Perhaps the warmer weather will hurry them along, too!

Stewardship Projects Proceeded

A few cold but clear days provided suitable conditions for Dr. Ben’s VanderWeide’s park projects.  Along with the prescribed burn in March and hand-sowing the fields of Bear Creek with native seed, Ben, Alex Kriebel (stewardship specialist with Oakland Township Parks), Ian Ableson (a new stewardship employee at Six Rivers Land Conservancy), and 4 volunteers began the yearly monitoring of vernal pools. As part of a larger project of the Michigan Natural Features Inventory, Ben monitors these biodiversity hotspots three times over the summer. What a collection of unusual creatures! They wake and feed or quickly hatch, mature, mate, lay eggs and expire in these temporary ponds that dry over the summer. Great to know our vernal pools are teeming with life!

The Promise of Full-fledged Spring

A young girl flies her kite at Bear Creek Nature Park on a spring-like afternoon.

We humans know how to take advantage of spring-like weather, just as the wildlife does. One warm, cloudy afternoon, a small girl brought her kite to test the April winds. This youngster got her long-tailed kite flying high and kept it there. So great to see parents bringing young children out to play surrounded by nature in our parks.

Last weekend, I think most of us dared to hope that “real spring” had finally arrived. The air was softer, the temperature more normal for late April, and a brighter sun warmed our upturned faces from a blue sky. Leaf buds that have waited on branches all winter have begun to swell. Soon more of those buds will open and our world will slowly dress itself in spring’s lovely shade of green. More migrators will navigate hundreds or even thousands of miles, making use of the sun, the stars and earth’s magnetic fields to find their way back to us.  Mornings and sunsets will be filled with more chatter and birdsong. So try to keep your eyes and ears alert!  Spring’s full-fledged arrival is just beginning to burst forth in full glory.

Cranberry Lake Park: Have Hope! Sure but Subtle Signs of Spring!

The solstice has passed; the days and nights get equal time. But when I’m shivering, my fingers and ears go numb in a stiff  wind, I struggle to hold on to the idea that we’re heading into spring. Until, that is, I head into the parks.

Blog by Cam Mannino

In mid-March,  water birds began splashing down in Cranberry Lake, finding any narrow stretch of open water within the ice sheet. They floated and fed – until one glorious morning, the whole lake turned liquid and bright blue! Migrating flocks honked, chattered and wheeled overhead. Some stopped to rest and feed before heading further north; others explored nesting sites. Our year ’round residents tuned up their spring songs. Territories must be established! Potential mates must be impressed! Best of all, the tiny frogs thawed after their frozen winter state – and now they are  singing! Can genuine spring, with its fulsome birdsong and burgeoning buds be far behind? I think not!

Water Birds Arrive Early, Despite the Ice – and the Muskrats Emerge, too!

It always impresses me that some of the first migrators to arrive in early spring are the water birds! They float, seemingly content, in the icy cracks that form as the sun begins to work on the frozen lake surface. Their cold water strategies involve body fat, oiled feathers, down insulation, and a circulation system which allows cool blood coming up from their feet to pass close to  warm blood traveling down, warming it as it returns to the heart. Below a group of Common Mergansers – black-headed males and brown-headed females –  glided along a thin channel of water on the far side of Cranberry Lake’s iced-over surface.

Common Mergansers – black-headed males, brown-headed females – find a small slit of open water at Cranberry Lake early in March.

Off in the distance, the Wednesday birders spotted the hunched silhouette of a Muskrat (Ondatra zibethicus) perched on the edge of the ice as a goose floated nearby. It slipped in and out of the water, hungry no doubt for food but also for a meager scrap of sunlight after living under the ice all winter!

Two sunny but cold days later, the ice had disappeared and the lake was bright blue and busy with migrating ducks and geese. Two Bufflehead (Bucephala albeola) and a group of Ring-necked Ducks (Aythya collaris)black-and-white males and brown females –   dove and surfaced as they foraged near a Canada Goose (Branta canadensis).

A group of Ring-necked Ducks and two Bufflehead dove and rose next to a Canada Goose as they rested and foraged in the lake.

I got a bit closer to a Bufflehead by checking from the opposite side of the lake. This lone male rocked along on the surface, bobbing under to feed every few minutes. Cornell Lab of Ornithology says Bufflehead accomplish this dive  by compressing their feathers to drive out the air and then pitching forward. A few seconds later, they pop to the surface like a cork and float on.

The Bufflehead dives underwater by pitching forward with its feathers compressed to squeeze out the air, making it less buoyant and able to submerge.

And that same cold morning, what I think was a large muskrat came steaming across the pond toward the eastern side. At the time, I thought this bustling swimmer was a Beaver (Castor canadensis), since there is a large beaver lodge on the western side of the lake. But I’m just not sure of that, so I’m sticking with it being a large muskrat. In the water, its tail looked wide enough to be a beaver, but as it approached the shore, it just didn’t seem to be big enough to be a beaver, unless it was a yearling. And beavers tend to swim with only their heads out of the water. In any case, nice to see this furry fellow plying the pond in the sunshine. What do you think? Big muskrat or young beaver?

The width of this swimmer’s tail made me think this was a beaver, but I think now it was a large muskrat.
From this nearing shore photo, it appears I’ve seen a large muskrat, rather than a small beaver.

Hearing the ancient bugle of the Sandhill Crane (Antigone canadensis), I quickly looked up to see two in the distance, flying into the far end of the lake.  Aren’t we lucky that they breed in our wetlands?

 Spring Songs Signal the Beginning of the Mating Season

As I approached the park one icy afternoon, bright spring music reached my ear – Western Chorus Frogs. These tiny frogs (Pseudacris triseriata – about 1.5 inches long!) are daytime relatives of the nocturnal Spring Peepers (Pseudacris crucifer). They spent the winter frozen solid, no heartbeat, no brain activity, but protected by an anti-freeze of sorts that keeps their tissues from breaking down. Pretty amazing! They thaw out and start singing as the days lengthen. The first afternoon I scanned a wetland trying to see these tiny creatures that seemed to be singing right at my feet, but I could not spot one! So on a second try a few days later, I found a log to sit on near the wetland in the trees just east of the parking lot. After about 20 minutes with my binoculars, I finally spotted two (of the hundreds that were probably there!), the sacks beneath their chins bulging, as they tried to impress a female with their piercing calls. Have a look and a listen!

Two tiny Chorus Frogs with bulging necks sing to attract a mate in the shallow water of a wetland.

A male Northern Cardinal (Cardinalis cardinalis) sang from the tree tops in the eastern meadow, turning every few minutes to send his territory call in a new direction. He’s a bit faint on the recording below, so you might need to turn your volume up! I got a bit closer to another male in a bush near the parking lot later on. He was doing “call and response” with another cardinal hidden in the trees nearby.

And of course, the American Robins (Turdus migratorius) that went south to Ohio and Kentucky returned as well, joining the hardy ones that spent the winter here.

One of many Robins that have returned from Ohio and Kentucky to breed here in the summer.

His spring call is also a bit soft.  And he makes a longish pause before his second “tit whoo” call.

Woodpeckers, of course, use drumming to establish territories, rather than singing.  Both male and female Downy Woodpeckers (Picoides pubescens) attract mates and protect territories with drumming. You can hear their typical drum roll in this Cornell Lab recording which was put to use by the little female Downy below.

I get a huge kick out of hearing flocks of American Goldfinches (Spinus tristis) chirp in the shrubs and small trees. To my ear, they are the only bird that actually says “tweet, tweet, tweet!”  Have a listen at this link and see if you agree! The males are currently molting into their bright yellow summer outfits.

Groups of American Goldfinches are singing their “tweet, tweet” calls in Cranberry Lake Park right now.

On a bird walk one Wednesday, we heard the far distant, insistent drumming of a Pileated Woodpecker (Dryocopus pileatus). Mark, one of the great spotters in the bird group, finally located it with binoculars on a very distant tree, and suddenly its mate (we assumed) dove across the trail far ahead of us before slipping up and away between the trees. No chance for a photo.  But here’s an incredible closeup by talented photographer Monica Krancevic at iNaturalist.org.

The First Blooms and Some Sturdy Ferns Wait Patiently

The lovely red blossoms of the Silver Maple (Acer saccharinum) brighten gray days in early spring. They emerge on bare branches before the leaves and are pollinated by the wind before butterflies or other insects emerge and start to pollinate. Those big clusters of scarlet florets are a great food source for hungry squirrels in the spring, when food is scarce, since nuts and seeds are either already eaten or beginning to crack open and sprout.  Last week, I found these male (staminate) clusters fallen from the treetops onto the exposed roots of a large silver maple. I love how the red at the edge of the root echoes the red of the flowers.

The scarlet blossoms of a silver maple are echoed in the root of the tree itself.

Take a closer look at this cluster of florets, some still closed, others waving stamens that have already shed their pollen to wind.  Once pollinated, the female florets will produce winged fruits, called samaras.

A closeup of a cluster of male florets, some closed, some with their stamens already emptied of pollen.

Nearby on the trail to the lake, some sturdy ferns survived the winter with fertile fronds intact.  The brown beads below are the sporangia on the fertile fronds of the Sensitive Fern (Onoclea sensibilis) that carry the spores for this year’s crop of new plants. On the right, are the vegetative fronds that provide sugars through photosynthesis in the summer months.

And the feathery ones below left are the fertile fronds of Ostrich Fern (Matteuccia struthiopteris) whose spores will be released and carried by the wind in the spring. Their vegetative fronds on the right stood tall and bright green, taking advantage of the moist soil and spotty sunshine in the forest.

Spring Just Peeks Out…Here and There

A pair of Canada Geese rest in the quiet refuge of a shaded wetland

Behind a scrim of small trees on the way to the lake, I spotted these two Canada Geese floating serenely in a secluded wetland, away from the noisy flocks gathering on the lake. They reminded me that, at this time of year, spring has to be sought out. It appears and disappears. One day the lake is iced over, a few days later it’s rippling and blue and then the snow falls again. On some days, spring isn’t easily seen – just a few red blossom clusters floating in a vernal pool  or scattered on the lifeless grass. Sometimes spring can only be heard and not seen. Frogs as tiny as your thumb sing unseen one day and the next, perch on a bit of floating grass, their throats bulging with amorous sound. Flocks twitter or honk high in a cold blue sky or male birds rehearse the first tentative versions of their mating songs. Woodpeckers tap out a seductive rhythm on the bark of trees.

The Eastern Meadow at Cranberry Lake doesn’t look very spring-like yet – but the clues are there.

Early spring isn’t flamboyant and colorful, like it will be in a few weeks. It’s hesitant, waiting to be found and enjoyed if we can only slow down enough. If we watch, we’ll see it peeking through the alternating rain or snowfall, cracking and opening in thawing ponds or hear it whistling, chirping, trilling from inside the brush or high in the treetops. So I hope you have time to delight in these  subtle hints of early spring as they unfold. It won’t be long now…

Photos of the Week: Nature During “The Big Freeze”

The mighty oak at Ilsley Park on a wintry morning

Since we seem to be heading into a warming trend, I thought I’d share the odds ‘n’ ends of what I’m calling The Big Freeze, those recent days of frigid temperatures and wind.  In the interests of preserving my camera and my numb fingers, my hikes during  the Big Freeze were shorter and the photos were fewer.

Blog by Cam Mannino

But as usual, I delighted in the sightings or even the  signs and traces of other creatures, including other humans, who shared the bitter temperatures with me.  On those frigid, silent days, I found myself appreciating the slightest visual treat that passed unnoticed in the lushness of summer  – a rock, a mud puddle, snow-covered mushrooms.  So here’s a sampling from Bear Creek and Charles Ilsley Parks of what can make a walk worthwhile even on the zero degree days of a challenging winter.

Wildlife Braving The Big Freeze

Flocks of Cedar Waxwings brightened a cold morning at Bear Creek Nature Park with color and friendly chatter.

Birds are rarer sights for me on super cold winter walks, so what a treat to come across a flock of Cedar Waxwings (Bombycilla cedrorum) on two different walks at Bear Creek Nature Park. The high-pitched whistling as these winter social groups swooped and settled was quite cheering during The Big Freeze. Here are some other creatures that shared those bitter morning walks with me.

Far in the distance early one morning, a Red-tailed Hawk plumped its feathers for warmth as it surveyed Bear Creek Nature Park.
American Red Squirrels (Tamiasciurus hudsonicus) don an auburn stripe down their back and tail for extra warmth on winter days.
A Northern Cardinal (Cardinalis cardinalis) dove through the bushes  foraging for food one snowy morning.
The Red-bellied Woodpecker’s “kwirr” call announces its presence. Its drumming is rapid, short and surprisingly soft for such a large bird.

Though I heard more creatures deep in the brambles and watched birds fly overhead, I only caught a few with my camera.  Some animals only left their tracks behind. On a bird walk at Charles Ilsley Park, we saw the neat tracks of two coyotes who’d trotted along in the moonlight the night before. Coyotes make straight, single tracks, placing their back feet in the tracks of their front feet to save energy. One of the birders said he’d heard that the coyote’s tail can leave a slight drag line as seen in the closeup below. I couldn’t find a source for that, but it makes sense since coyotes run with their tails down, rather than up like wolves or dogs. Click on the photos to enlarge; hover your cursor for captions.

A Meadow Vole (Microtus pennsylvanicus), aka a Meadow Mouse,  must have crossed the path at Bear Creek Nature Park on a snowy night and then disappeared by burrowing into the snow. Lucky for this little creature that the coyote wasn’t around! (Meadow Vole photo by Wolfgang Siebeneich at inaturalist.org.)

I’ve never seen a Pileated Woodpecker (Dryocopus pileatus) at Bear Creek Nature Park, though others have. But I did see the hole one had recently excavated in a tree  in the Oak- Hickory forest there – with this “carpenter’s” wood chips scattered below. (Woodpecker photo kindly lent by Joan Bonin, a gifted local photographer.)

Evidence of Humans at Play During the Big Freeze

It’s always cheering to come upon evidence of other people using our parks to just play in the snow.

Odds ‘n’ Ends that Caught My Winter Eye

The austerity of winter reveals landscape features unnoticed in the lushness of spring and summer.  The birding group marveled at a fast-running spring  flowing out into the snow at Charles Ilsley Park which had been dry or hidden in the dense growth of the field the rest of the year.

At sunset one afternoon, I rounded the corner of the shed at Bear Creek Nature Park and saw a pink and blue sunset glowing in a puddle of melted snow.

The graceful “bones” of last year’s wildflowers, clusters of half-moon shelf mushrooms, even an unusual rock catch my eye when framed in white. (Use pause button if you need more time for captions.)

 Beauty in the Big Freeze: Appreciating the Small Things

Plant material below the surface colors the ice on a wetland at Bear Creek Nature Park.

Sometimes it’s just the pale green and lavender of ice in a wetland or the high whistle of a swoop of Cedar Waxwings. The scarlet flash of a Cardinal or a dancing snowman can lift your heart on gray winter day. Feathery snow settling on a seed pod or the gaudy beauty of an early sunset – it’s just a matter of taking in beauty in smaller, more subtle doses that can buoy our spirits in the dark cold of a Michigan winter.

Beauty in Every Season: A Year-End Review of our Parks and Natural Areas

Oakland Township Stewardship Manager Ben VanderWeide and I both got inspired by the idea of a year-end reflection on some of  the remarkable sights in our parks and natural areas over the last year. Nature excels in surprising and delighting any curious observer with its ability to come back from adversity, in some cases to even thrive in difficult circumstances. That ability to keep on growing and creating in the face of any obstacle can be a great inspiration in challenging times.

So as the snow falls, please sit back in a comfortable chair with a warm drink and savor  some highlights from the four seasons of 2017 here in Oakland Township.

Winter 2017: Serenity Rises as the Snow Falls

The Tree Line Between Two Prairies, Charles Ilsley Park

Sometimes we just need a little less hubbub after the holidays and the parks provide a  peaceful escape. In general, the only sounds are the wind in bare branches, the occasional calls of the year ’round birds and the tapping  of energetic woodpeckers foraging in the tree bark. And other times,  when we feel  a bit house-bound and crave crisp air on red cheeks,  a winter walk provides little discoveries unavailable in other seasons. During one deep freeze last winter, the weekly birding group stepped out on the ice at Cranberry Lake to inspect a beaver lodge. And a few weeks later,  I plopped down in the snow for a closer look at 3-D ice dendrites standing upright on a frozen puddle! Folks enjoyed the fine skating rink at Marsh View Park, but some who fancied wild surroundings skated on Twin Lake. On sunny winter days, shadows are always sharp and any spot of color, like the brilliant red of a male cardinal,  catches my  eye in winter’s clear, white light. Hiking in winter can be wonderful; just be sure you’re bundled up for it! (Click on pause button for longer captions.)

Spring 2017: Buds, First Blooms, Migrators Flying in by Night and the Ebullient Symphony of Courting Birds and Frogs

Golden Alexanders carpet the woods near the Wet Prairie along the Paint Creek Trail

Ah, mud-luscious spring! The tiny Chorus and Wood Frogs thawed out after their winter freeze and sang lustily from vernal ponds. In early spring, the birders spotted a crayfish at Bear Creek who’d climbed out of her chimney with eggs under her tail and was lumbering toward the pond. Some spring avian migrators quickly passed through, and we bird watchers were lucky to spot a few special visitors. An unusual American Pipit appeared before my camera lens one afternoon at Gallagher Creek Park on its way to its breeding grounds in the far north. While others, like the Tree Swallow or the Eastern Meadowlark, settled in for the summer to raise their young. After last year’s controlled burn, native Lupines appeared along the Paint Creek Trail. And in May, Ben spotted a rare sight, a frilly spread of rare Bogbean flowers in a kettle wetland at Bald Mountain State Recreation Area off Kern Road. Snow melt and bright green buds always offer an irresistible invitation to come out and join the bustle and music of spring!

Summer 2017: Butterflies Galore as Restored Prairies Began to Bloom

East Prairie Ilsley 2017 (1)
Member of the birding group at Charles Ilsley Park in July

Summer! The very word conjures up a coloring box assortment of butterflies hovering over prairie wildflowers. Birds constructed their nests and later wore themselves out feeding noisy, demanding fledglings. We birders particularly enjoyed close looks at a male Rose-breasted Grosbeak sharing egg-warming duties near a Bear Creek path. The birders laughed in surprise watching  a passive/aggressive pair of Canada Geese successfully discourage the presence of a Green Heron by simply swimming uncomfortably close to it.  A family ambled along a path at Draper Twin Lake Park, headed for a morning fishing expedition.  The birding group, binoculars in hand,  spotted an Indigo Bunting while walking the new paths through the prairies at Charles Ilsley Park, increasingly spangled with colorful native wildflowers as restoration proceeds. A Great Horned Owl stared at the delighted birding group through a scrim of leaves near Bear Creek marsh.  Every path in the township hummed with life during the summer months. But that’s what we all expect of summer, right?

Autumn 2017:  Birds Departed South, and Fall Wildflowers Bloomed

Autumn color at Cranberry Lake Park

Tundra Swans flew in formation overhead,  as migrators of all kinds, like the Hermit Thrush, rode the north wind down to southern climes. But as they departed, nature offered a consolation.  Many native wildflowers bloomed in the cool weather as they faithfully do each year. Asters formed carpets of color everywhere, from meadow to marsh! At the Wet Prairie on the Paint Creek Trail,  tiny Ladies Tresses orchids, Grass of Parnassus with its delicately striped petals, and vivid purple Fringed Gentian intrigued me again by emerging in the chill of early autumn. Native bumblebees pushed their way into Bottle Gentian flowers at Gallagher Creek Park and the Wet Prairie. Butterflies still sipped nectar from late fall blooms. The birders identified ducks of all kinds assembled in rafts on Cranberry Lake. Rattling cries alerted me to the presence of  Belted Kingfishers who scouted for prey at  both Bear Creek’s pond and Cranberry Lake. Ben dipped his net into a marsh at Charles Ilsley Park to show us tadpoles that overwinter on the muddy surface beneath the water. So much life as the year 2017 began to ebb!

Parks Full of Life All Year ‘Round. Aren’t We Lucky?

As a direct result of the foresight of township residents who have supported the Parks Commission and land preservation, native plants, wildlife, birds, and a beautifully diverse combination of habitats are being restored and preserved in Oakland Township. I want to share my appreciation for that foresight and for the hard work and knowledge of Ben VanderWeide (my kind and able supervisor and editor), other parks volunteers, my fellow birders and park staff.  And at the end of the year, I thank all of you who read, comment on and/or follow Natural Areas Notebook. It’s wonderful to be learning more all the time about the natural world – and then to have this opportunity to share what I’m learning with all of you. On to 2018!

Cranberry Lake Park: Prepping for Winter, Sowing for Spring

One of the many spots where meadow meets woods at Cranberry Lake Park

Cranberry Lake Park, with its varied habitats, gives an autumn visitor lots of possibilities. In October, the lake hosts huge bobbing rafts of water birds, feeding and resting on their way south. The grassy trails lead you to expansive meadows covered now by the soft gray of seeding goldenrod, where migratory birds converse in the bushes while harvesting seed. Or you can choose the shady Hickory Lane to the west or the dappled light of the maple forest to the north if you’re in the mood for a woodland walk.

My visits were scattered throughout the month –  unusually warm days early on, a sunset hike one breezy evening, and finally a cold, rainy morning right before first frost. Each time I rediscovered how sensibly nature prepares for a winter rest and a bountiful spring. 

 

 

Cranberry Lake Itself  – A Thwarted Kingfisher, a Remarkable Grebe, and Diving Ducks of All Kinds

The edge of Cranberry lake at the end of an eastern trail.

Cranberry Lake welcomes all kinds of water birds as they begin their long journeys to southern climes. One cold, wet morning, I watched a bird hovering vertically high above the water, head down, scanning the surface below. Suddenly, it gave a loud rattling cry and headed for a leafless tree near the shore. An agitated male Belted Kingfisher (Megaceryle alcyon) shouted its noisy call from a bare limb. Perhaps he was put out by not spotting prey from that perch either!

This male Belted Kingfisher had one slate blue belt on his chest. The female has a chestnut brown belt and a blue one.

A small Killdeer (Charadrius vociferus) flew in to probe the edge of a mud flat, landing near a Canada Goose (Branta canadensis). Quite an odd couple!

A Killdeer shares a mud flat in the lake with a Canada Goose.

Killdeer are wading birds, being Plovers, but I’ve most often seen them in barren fields, either scurrying along scaring up insects or keening in flight to distract predators.  This one, though, looked right at home as it probed the mud for insect larvae or other aquatic prey before beginning migration.

Far out on the lake, a huge mixed flock of migrating ducks and other water birds, well over 200 of them, floated on the surface, foraged for food, or slept and preened on the mud flats in the shallower parts of the lake.

After studying the photo magnified, Ben guessed that most of the birds were Ring-necked Ducks (Aythya collaris) which are diving ducks. Unlike mallards and other dabbling ducks who simply tip upside down to feed, diving ducks have legs set far back on their bodies.  As a result, they need to run across water, wings flapping,  to get into the air and are awkward on land – but they dive, feed and swim underwater with ease!

(Since most of the Cranberry Lake flock was far from shore, the closeup photos of diving ducks below are all from inaturalist.org photographers. My thanks to all of them and to Creative Commons where they license their work.)

Two other diving ducks that Ben thinks may have been in this flock include Redhead (Aythya americana) which are so social that they’re also referred to as “rafting ducks” and  Lesser Scaup (Aythya affinis). According to the Cornell Ornithology Lab, Lesser Scaup chicks “are capable of diving under water on their hatching day, but they are too buoyant to stay under for more than just a moment. By the time they are 5 to 7 weeks old they are able to…swim underwater for 15-18 meters (50-60 ft).” Here’s a wonderful closeup of a Redhead by photographer lonnyholmes and a Lesser Scaup photo by photographer Paul Sullivan. (Hover cursor for captions; click on photos to enlarge.)

Far out in the lake, through my binoculars, I also spotted Bufflehead, another diving duck,  on their way from the boreal forests of Canada and Alaska, where according to Cornell, they “nest almost exclusively in holes excavated by Northern Flickers and, on occasion, by Pileated Woodpeckers.” Unfortunately the male and three female/juvenile Bufflehead that I saw at were too far for my longest lens to reach clearly. So on the left is my distance photo from Cranberry Lake (click to enlarge) and  on the right is a closeup from a  photographer at inaturalist.org who uses the name dlbowls showing the male’s dark head iridescent in the sunlight.

Feeding alone on a rainy morning, the solitary  Pied-billed Grebe (Podilymbus podiceps) dove repeatedly into the gray surface of the lake. Modest brown this time of year,  these grebes bills turn white with a neat black band in breeding season. Pied-billed Grebes control their buoyancy by trapping water in their feathers. According to Cornell Lab, this allows them to escape danger by doing what children might call “belly smackers” – “plunging with head and tail raised above the belly, making a splash. They can also dive head first, or simply sink quietly out of view, leaving no trace. Parents dive with young clamped under their wings … These grebes often avoid danger by submerging, crocodile-style, with just the eyes and nostrils above the surface.”

The little grebe at Cranberry Lake gave me a brief demonstration of the submerging tactic –  first trapping water in its feathers , then settling back down on the water, and finally beginning to submerge like a little submarine.  What a trick!  I’m very taken with this little bird.

Wide, Sunny Meadows Surrounded by Autumn Color

A meadow on the north end of the park

On the trails that lead toward the meadows, small brown birds dash from bush to bush or dart down into the grass.  Some are tiny migrators who might appear modest and plain until you see them through binoculars or a camera lens. Chubby White-throated Sparrows (Zonotrichia albicollis), with their yellow “lores” and striped heads, hung out in small flocks, keeping in contact with soft seep calls.

The White-Crowned Sparrow has yellow “lores” – spots in the corners of its eyes.

Another brown migrant paused in the bushes along the trail from the lake – the Hermit Thrush (Catharus guttatus). These normally solitary birds are often quite secretive – hence the name, perhaps? They’re well-dressed hermits, though, with their chocolate back, spotted breast and white eye ring. And during migration, they do sometimes forage with or near other small birds.

The Song Sparrow (Melospiza melodia) is silent now, no longer burbling its song from high in a bush as it did this spring and summer. In fact, this one glowered from the bare branches, seeming a bit put-out by my presence. Or maybe it’s just irritable about having to migrate, though  it will only travel a short distance to the south.

At the edge of a small meadow, a year-round resident, the American Goldfinch (Spinus tristis) pecked delicately at the seeds of Common Evening-Primrose (Oenothera biennis) that nicely complemented its muted gold.

An American Goldfinch fed in its modest winter feathers.

And another year ’rounder, the Northern Cardinal (Cardinalis cardinalis) stared from the drooping vines of Oriental Bittersweet (Celastrus orbiculatus), an aggressive, invasive plant that strangles, shades out and topples trees. Two trees along the trail had fallen recently due to masses of this vine in their canopies. Those orange and red fall fruits are disastrously appealing to birds, who spread their seeds far and wide.

On my early October visits, insects were still very much in evidence. One warm October afternoon, a busy group of adult and juvenile Large Milkweed Bugs (Oncopeltus fasciatus) fed eagerly on the seeds of Common Milkweed (Ascelpias syriaca) in a southern meadow. The large beetles below are adults accompanied by the mostly red juveniles. They eat milkweed seeds by injecting saliva through the seed’s surface which liquifies it so it can be sucked through their straw-like rostrums. Milkweeds produce lots of seeds, so luckily these beetles, though destructive to individual pods, don’t really do a lot of damage in a season. And they are kind of jazzy looking, don’t you think?

Red-legged Grasshoppers (Melanoplus femurrubrum) mate in the autumn and lay their eggs in the earth. The eggs won’t finish developing until spring, when the first nymphs emerge. They’ll molt 5-7 times during the summer before they are fully adult, like this pair on a grassy trail.

A female (left and larger) and male Red-legged Grasshopper will lay eggs that will hatch next spring.

As October moved on, the goldenrods – Canada Goldenrod (Solidago canadensis) and late blooming Showy Goldenrod (Solidago speciosa) – began to seed, casting a silver-brown patina over the meadows.

Despite the cooler days, the small Autumn Meadowhawk (Sympetrum vicinum) still glided along the meadow paths, stopping on a fallen Canada Goldenrod stem to warm its wings in the autumn sunlight. The yellow-orange blush on the wings near the thorax is a distinguishing field mark. Autumn Meadowhawks fly later than most other species in our area, but are usually gone by early November, having laid their eggs along the lake’s shoreline.

The Hickory Lane and Wooded Wetlands – Filtered Light, Foraging Nut Eaters, a Frog and Puffballs

The Hickory Lane at sunset

Woodland walks are magical in the early morning or just before sunset. The light filters down through a golden shimmer of falling leaves and sometimes sets a crimson leaf aglow.

A Silver Maple leaf (Acer saccharinum) in the northern forest  set aglow in morning light.

On a warm walk in early October, the bright yellow caterpillar of a Spotted Tussock Moth (Lophocampa maculata) caught my eye within the dry leaves on the Hickory Lane. Such a fancy caterpillar! Research in Caterpillars of Eastern North America seems to indicate that  it’s the middle instar of the Spotted Tussock moth because in earlier stages, the end sections of this yellow caterpillar are completely black – but I’m open to correction by more knowledgeable readers!

An Eastern Chipmunk (Tamias striatus) on the Hickory Lane basked in the sunset, perhaps resting from a long day of ferrying nuts in its cheeks to stock its underground burrow. It won’t hibernate, but when it wakes periodically from its winter torpor, it will need a little sustenance before snoozing again.

An Eastern Chipmunk rests from its seed and nut-gathering labors before winter.

A Gray Squirrel (Sciurus carolinensis) dashed quickly up a tree on the Hickory Lane (in this case, it’s the black morph). And nearby, an American Red Squirrel (Tamiasciurus hudsonicus) did the same. I wondered if they had enjoyed some of the hickory nuts that were neatly opened on a fallen log not too far away.

Almost invariably, curious deer emerge at the edge of the woods, and they too are putting on weight for winter. They eat lots of nuts, including plenty of acorns, this time of year. Their love of acorns in the fall and saplings during the winter can make it harder for our oak forests to regenerate. This doe looks like she’s definitely eaten her share and is ready for cold days ahead!

In a pond hidden in the trees, a Muskrat (Ondatra zibethicus) had built a roomy “push-up” den in which it can eat above the water line. Muskrats don’t hibernate, but spend the winter cruising very slowly beneath the ice. What appears to be a hole is probably just plant matter or mud, since muskrats generally enter their push-up dens from under the water through a tunnel that leads up to a cavity at the center.  According to Wikipedia, “In snowy areas, they keep the openings to their push-ups closed by plugging them with vegetation, which they replace every day.”

Near that woodland pond in late October, a tiny masked Wood Frog (Rana sylvatica) literally sat “like a bump on a log,” staring off into the distance, partially lit by the green light of a leaf. Wood Frogs love forested wetlands like this during the summer. But this little frog may be preparing for winter. It will move upland, away from the water, burrow under leaves or a log. Then most of the water in its body will freeze solid, and its breathing and heartbeats will stop! But it will thaw in the spring and go right back to the pond to mate. Hope this little one finds a cozy spot before long.

The astonishing Wood Frog freezes solid in the winter and thaws out in the spring.

On a fallen long nearby, my husband and I came across  a colony of Puffball Mushrooms (division Basidiomycota) just as we did last year. These stalkless mushrooms would disperse spores on their own, of course, but I asked my husband to poke a couple in order to catch the brownish cloud of spores escaping through their tiny apertures. Wikipedia says falling raindrops disperse puffball spores in a similar way.

On my last visit just before first frost, under moist trees in these wooded wetlands, the Sensitive Ferns’ green, leafy, sterile fronds (Onoclea sensibilis) were already withering in the dropping temperatures. But the separate fertile fronds, covered in brown beads called “sori” that contain next year’s spores, stood erect in the grass beneath the trees.

Quietly Prepping for Winter and Another Spring

Cranberry Lake Park, like all of nature, provides testimony every autumn that the year is not “dying” as is so often said of this season. On the contrary. At every turn in the trails, nature is sensibly preparing for winter and sowing for spring. Yes, plants wither – but their seeds, stems, and roots wait within the soil for warm spring light. Gray-brown bracken will eventually fall, nourishing the soil in which those seeds can grow. Bright leaves fade and fall, of course, but only because trees are in “dormancy,” resting, slowing their metabolism, preserving themselves for next spring’s surge of growth. Some insects migrate, others winter-over under bark or within plants, while still others perish, leaving behind eggs which bide their time beneath the earth. Birds fly south, frogs burrow under logs, and animals of all sorts settle into winter quarters. Nature doesn’t resist change. It simply adapts to it, with every intention of burgeoning forth with gusto in the spring. We humans probably do best when we follow nature’s lead by just letting nature take its course –  preparing for longer nights and colder days, while confidently sowing seeds – both literally and metaphorically – for a future spring.
