Bear Creek Nature Park: Color! Song! A Sensory Trip Through Early Spring

The dry stalks of native Little Bluestem grasses paint a splash of soft orange on the somber canvas of spring..

Gray clouds blanket our April skies in Michigan – but the occasional bright blue day or a beam of pale sunlight slipping between the rain clouds can lift our spirits in a giddy instant. The earth emerges from its snow cover in shades of gray and brown – but summer birds return dressed in their spring finery, ready to join others in exuberant song.

Hibernators poke their heads from tree holes or slip out of the leaf litter or swim up from thawing ponds, ready to nurture a new generation of young. Early spring takes its time, offering us just a few tastes here and there of the colorful bustle ahead as the days grow longer.

Visitor Birds Fly In Bearing Color and Song on Their Bright Wings

I hope you’ve been able to open a window or step out your door to listen to the birds’ dawn chorus in the last few days. Just in case, I thought I’d play a recording I made outside our home last Sunday morning. If you increase your volume,  you’ll hear the insistent call of Northern Cardinal, the buzzing call of a Red-winged Blackbird, the “kwirrr call of the Red-bellied Woodpecker (Melanerpes carolinus), the “tweeeeets” of American Goldfinches (Spinus tristis) and in the background, Canada Geese (Branta canadensis) high overhead, plus a few smaller birds twittering along.  It’s a joyful noise after a cold winter.

The male Northern Cardinal (Cardinalis cardinalis) you heard above, of course, has provided splashes of scarlet against the snow all winter.  But now some old friends are arriving for the summer, brightening up an April day. Members of our birding group heard the high pitched whistling calls of Cedar Waxwings (Bombycilla cedrorum) and then spotted a small group that had settled into trees near a Bear Creek Nature Park wetland. The yellow tips of their tails and yellow bellies added a spot of sunshine on a blue/gray morning. Though Waxwings can stay here year ’round, I see Waxwings less often in the winter. I’m glad some of them choose to nest in Bear Creek each year.

As a friend and I skirted the eastern edge of the Center Pond one afternoon, we heard a splash and looked up to see a female Belted Kingfisher (Megaceryle alcyon) flying up into a tree with her quarry. She swallowed it, though, before I got her picture. Her blue and rust colored belts show that she’s a female.

The male has only one blue belt. Fortunately, last Sunday, the male was at the Center Pond. When my husband and I arrived, the kingfisher was very agitated, calling as he dashed from tree to tree. These kingfishers don’t sing. At best, their fast, rat-a-tat rattle provides the other birds’ vocals with a little background percussion.

The gorgeous male Wood Duck (Aix sponsa) brought more than his share of brilliant color to the chilly waters of the Playground Pond. Together he and his mate will scout for a nesting hole high in the top of a tree near water in the woods nearby. Wood Duck nestlings are “precocial,”  meaning born ready to go – eyes open, covered in feathers and, in their case, outfitted with claws for climbing. Only days after birth, they claw their way up to the edge of their nest cavity and leap into the air, following their mother’s calls below.  They fall harmlessly into the leaf litter or water and join her in the the nearest pond to feed. Amazing feat for a baby bird! The adult birds make quite a racket when taking flight, the male’s “zeet” call is very different from the female’s “oo-eek.”

Though Wood Ducks generally choose a mate in January, this one seemed to have arrived alone. A few days later, his mate showed up.

The diminutive Ruby-crowned Kinglet (Regulus calendula) repeatedly sang his lovely up-and-down spring song while he hopped about frenetically in a cluster of vines near the Playground Pond. Through the tangled branches, I could see the red crown raised slightly atop his head, but never got a clear shot. Luckily, gifted local photographer, Joan Bonin, got a lovely photo when a kinglet posed on a branch for her at Holland Ponds in Shelby Township. Thanks to Joan for sharing her excellent photographs for the blog!

In his brilliant iridescent green head, yellow beak and orange legs, the Mallard  (Anas platyrhynchos) seemed to be leading his more modestly dress mate around the Playground Pond one afternoon. But when the female Mallard spotted me, she turned and swam away, quacking insistently until the male looked around nervously, saw me and fled toward her, scrambling awkwardly across some submerged logs to catch up with his mate. By the way, that famous  “Quack!” is only given by Mallard females. Have a listen to it along with male’s very different call at this link.

A pair of mallards cruised the Playground Pond, keeping an eye on the Wood Duck.

Near the Walnut Lane, a wonderful ripple of song flowed down from the treetops. After a bit of peering around, high above I spotted an American Robin holding forth repeatedly with his up-and-down lilting spring song. I recorded his music and then looked up and took a photo from an angle I hadn’t noticed before. I got a worm’s eye view, you might say, of that very sharp, probing beak and felt glad it wasn’t being thrust in my direction!

Over in the marsh, the male Red-winged Blackbirds have been clucking and buzzing from atop the cat-tails for a couple of weeks as a way of establishing territory. Last week, the females began to arrive. Maybe their dark striping lets them blend safely into the shadows while they tend their nests among the stems down near the water. (Click on photos to enlarge; hover cursor for captions.)

And Then the Frogs Join the Chorus!

After one warm April day, the hibernating spring frogs broke into song. Every wetland at Bear Creek trilled with the high-pitched peeping of Chorus Frogs (genus Pseudacris) and lower chuckling gurgle of the Wood Frogs. Both have been frozen all winter with no heartbeat and no brain waves but enough built-in anti-freeze in their cells to somehow stay alive. And as soon as they warm up, they’re ready to sing!

The Wood Frogs, like the one above,  are easier to spot because they croak while floating on the surface,  flexing their legs in an occasional kick. The thrust creates concentric circles in the water around them, so I look for the little masked frogs in the middle of those circles. Most Chorus frogs are harder to see, usually huddled on, against or under logs. I haven’t spotted one yet this spring, (though their piercing songs can be deafening up close! Here’s a photo, though, from a previous year.

A Chorus Frog in mid-cheep.

Some of our local Chorus Frogs, Spring Peepers, (Pseudacris crucifer) are nocturnal. I imagine that the Bear Creek Nature Park neighbors are hearing them when the sun sets, or will shortly. If you see one sleeping on a leaf during the day as I did once, you’ll see the “X” on its back just behind its head, though it’s hard to see in this shot. Isn’t it tiny?

Spring peepers are the nocturnal spring frog you’re hearing at night.

Other Hibernators Emerge…

The Raccoon (Procyon lotor) that I watch for every year in the oak-hickory forest has already given birth to four kits.  One of them is what’s sometimes called a “blond morph”; it’s not an albino, just a different morph or phenotype of the raccoon. I saw a blond adult raccoon a few years ago in the same tree so that trait must be in the local gene pool. The four kits (one is barely visible at the back right) seem to be laying across their sleeping mother’s back in order  to get a good look at me. She’s probably catching up on her sleep after hunting all night to feed these youngsters!

Four raccoon kits , three of whom were checking me out. The one on the right is a light phenotype, which is unusual but not extremely rare.

A couple other hibernators made their first appearance in the last two weeks.  An Eastern Chipmunk (Tamias striatus), that had dozed off and on all winter in its multi-chambered den, emerged and just sat quietly in a patch of sunlight along the entrance trail. The light must take some getting used to after months underground, just waking now and then to eat stored nuts and seeds.

A quiet Chipmunk sat in the sunlight, enjoying being out its underground den after a long winter.

A pair of Midland Painted Turtles (Chrysemys picta marginata) kept each other company on a log in the Playground Pond last week. The slightly warmer water must have signaled them to leave their winter torpor in the mud below and swim up into the light and air. I wondered if these two were a pair; the lower one maintained a steady stare at the higher one, who paid no attention while I was there. They both probably were just staring off into the distance, though, as turtles often do.

Over in the marsh, a whole group of them gathered in the reeds and assumed exactly the same pose in order to soak up the sun on their dark shells.

A couple Snapping Turtles (Chelydra serpentina) surfaced in the marsh as well. One fed with its head down as it cruised the marsh, eating vegetation. It looked just like a slowly moving green lump! But the other, much smaller, was basking with its entire body encased in vivid green Duckweed (genus Lemna). It seems very content with the look, and probably feeling, it had created, eh?

Plants Begin to Bloom…and Butterflies (and others) aren’t Far Behind!

Just as spring was breaking and icy puddles were melting, I came across a little stream burbling through Bear Creek Nature Park’s eastern woods. This streams runs out of the Center Pond toward the marsh, joining Bear Creek after it leaves the march. Such a lovely spring sound!

On the north side of the Center Pond last week, the Willows (genus Salix) bloomed and (hooray!) we got our first glimpse this year of butterflies – and other pollinators.  First we saw one of the hibernating butterflies, the Mourning Cloak (Nymphalis antiopa). It looked a bit ragged from having spent the winter in a tree cavity or under loose bark on the snow-covered ground. It’s often the first butterfly I see in the spring. Mourning cloaks generally don’t pollinate much because they sip tree sap or the honeydew of aphids, rather than nectar from flowers. This one might have been displaying in order to attract a female.

Mourning Cloak on a blooming willow.

On the same plant, a migrator, the Red Admiral (Vanessa atalanta) posed. It does sip nectar but it also competes with other males for territory by showing off its flying skills. Perhaps that’s why this one was flitting busily from limb to limb.

A Red Admiral had migrated from the south, probably Texas, to land on this willow near the Center Pond last Sunday.

On one bloom, we saw what appeared a small Wasp (maybe suborder Apocrita). It seemed very busy enjoying the willow’s pollen.  According to Wikipedia, unlike the better known wasps, like Yellowjackets (fam. Vespidae), most wasps are solitary with each female living and breeding alone.

Over in a wetland on the west side of the marsh, the strange blossom of Skunk Cabbage (Symplocarpus foetidus) had thrust itself up out of the mud. Its purple and yellow spathe covers a tiny spike of petal-less flowers inside. The smell of skunk cabbage attracts early spring flies that pollinate this sci-fi looking blossom. It releases a skunk-like smell and a bitter taste when bruised which means most predators stay away, too. The stem of Skunk Cabbage remains beneath the ground and the green leaves rise after the flowers. Odd, how this eccentric plant with the nasty scent seems to reverse my expectations of how plants grow in the spring!

The flower of the Skunk Cabbage rises from the mud with a spike of tiny flowers protected by the purple and yellow cover of the spathe.

The brightest colors in the woods now, though, are the vivid greens of Moss (members of the Bryophytes). Spring light sifts through bare limbs providing enough sunlight to feed these interesting, ancient plants. The leafy green parts of moss are “gametophytes” that produce the gametes, sperm and ova. Once spring raindrops rinse the sperm across the surface of the moss to a waiting ovum, fertilization occurs and a tall thin “sporophyte” rises from the green surface. The sporophyte will eventually release it spores. These spores initiate thin filaments called the “protonema” out of which grow new gametophytes, starting a new patch of moss.

Here are what I’m guessing are three different stages of moss growing on the same tree near the marsh. Or maybe its three different mosses? I’m too much of an amateur naturalist to know.  I do know that I love the green glow of moss in the dappled light of the forest. (If you are knowledgeable about mosses, please feel free to correct my guesses and help me identify them! )

If mosses just don’t do it for you, don’t despair.  Thanks to last fall’s forestry mowing north of the pond, sun has already reached the sunny faces of the Blood Root (Sanguinaria canadensis). I admire its leafy cloak that rises with the flower wrapped inside.

Bloodroot bloomed early this year because sunlight reached it after the forestry mowing.

The first tender leaves and buds of the woodland wildflower, Spring Beauty (Claytonia virginica) are already rising at the feet of trees in the Oak-Hickory forest.

And out in the eastern meadow, a Pussy Willow (Salix discolor) began to bud a few weeks ago, while it peacefully hosts a wide assortment of developing insects within its pine cone-shaped Willow galls. Last Sunday, it had bloomed, but the insects didn’t seem to be issuing forth yet.

Slip on Your Boots and Your Raincoat!  Spring is Singing Its Siren Song

Song sparrow (Melospiza melodia) singing.

Spring’s a great time to act like a kid again. Try heading for the park on a rainy day and let the sounds and sights of spring cheer you like they did when you were small. Slosh through a puddle.  Squelch through some mud.  Leave your earbuds at home – and pause, eyes closed,  for a short serenade by a Robin or a Song Sparrow.  Use your binoculars to scan the wetlands for tiny frogs, their throats bulging with song. Let your color-starved eyes feast on  the yellow of a Waxwing’s belly, the emerald shine of a Mallard’s head,  the exotic, multi-colored pattern of a  Wood Duck’s plumage.  Swish your palm across a soft cushion of a vivd green moss. Perhaps even get close enough to a skunk cabbage to make your nose wrinkle. Our senses need a good workout after being indoors for so long.  Treat yourself to a walk in the park. I can pretty much guarantee you’ll come home  happier than when you left.  Works for me every single time.

Photo of the Week: Green Plants on a Snowy April Day

It was snowy this morning when I looked out the window. Yes, it was beautiful, and no, snow is not unusual in early April. But I’m getting a strong case of spring fever, so I needed to look for something green to brighten my day.

Enter mosses. They are the masters of shaking off a snowy day. One study found that Arctic mosses can ramp up photosynthesis within 332 seconds of snow removal. That’s less than 6 minutes! Mosses in southeast Michigan are equally hardy. They love the bright sunlight and moisture of early spring, ramping up photosynthesis quickly to soak up every bit of sun.

With the constant change between beautiful, sunny days and wintry weather, we need to take a lesson from the playbook of mosses: catch every bit of sun possible. The forecast calls for sun this weekend, so where are my hiking boots…?

THIS WEEK AT BEAR CREEK: In the Forest – Hawks Hunting, Smaller Birds Hiding, Deer Stalking and Dabs of Color plus Important Safety Info

November rain

Blog Post and Photos by Cam Mannino

This week Bear Creek again slipped from winter to fall and back again.  The pond and marsh iced over and then melted in steady rain.  The Eastern Old Field (above) glowed russet as the rain saturated every color in the park and the combination of wind and wet earth felled a large tree.  And then heavy frost descended, edging everything in white.  Over in the woods, raptors silently slipped through the branches searching for a meal, while smaller birds found places to hide.  Mushrooms, lichens and mosses painted  the forest  with dabs of color,  and deer stalked in the distance.  A transition time at Bear Creek.

 First, Some Safety Issues – and Practicalities

If you enter the park from Snell Road, you may see caution tape across the path leading into the park.  A large tree has fallen into another on the trail and is in danger of falling across the path.  I got a quick shot to satisfy the curiosity of park visitors, so please avoid the area until our trusty OT maintenance crew can remove the danger.  Feel free to go west past the Playground Pond or north down the path behind the playground that runs to the Center Pond.

Edit:  As of Saturday, December 5, the tree was removed and the path in from Snell Road is now open!  Thanks again to the Maintenance Crew for getting this taken care of.

falling tree at BC
A large tree has fallen into another along the Snell Road entrance. Hence the caution tape that prevents entrance by that path until the maintenance crew can remove it.

And speaking of the maintenance crew, many thanks to Doug Caruso, OT Maintenance Foreman, for washing the slippery gray mud that had washed onto the deck at the Center Pond after the rain.  Doug washing deckThe deck looks better and feels safer underfoot!

And speaking of cleaning things up, can I please urge Bear Creek visitors to use the Pet Waste stations this winter?  The maintenance crew just installed a new one at the south end of the Eastern Path, New pet bag station near subso if you forget your plastic bag, please pick one up there or at the Snell Parking lot and clean up after your dog.  Dog waste on white snow is not a pretty sight, and pet waste spreads disease into our water and wildife! And remember that dog leashes keep both other dogs and other walkers safer and happier in the park.  Thanks!

 The Forest:  Raptors Hunt and Smaller Birds Hide

When I walked into the woods near the marsh early last week, I heard the high, raw cry of a young Red-tailed Hawk (Buteo jamaicensis) and finally spotted it perched high in a tangle of branches near the water.  It flew above the treetops from there,  so here’s a photo of another young Red-Tailed Hawk on the hunt.

A young Red-tailed Hawk called and soared above the marsh. Young red-tails don’t have a red tail in their first year.

Nearby in the woods, a female Red-bellied Woodpecker (Melanerpes carolinus) moved nervously from tree to tree.  When the hawk soared away, she quickly flew to  a branch very close to one on which the hawk had perched.  I thought that was odd until I saw her disappear into a hole on the bottom side of the branch.  In a few seconds, her head peeked out as if she was checking to see if the coast was clear!  Good hiding place, isn’t it?

A Red-bellied Woodpecker’s found a nice, safe hole on the underside of a dead branch near the marsh.

If you’re unfamiliar with the appearance of this female year ’round resident, here’s a closeup of a female Red-belly, like the one in the hole above.  The red on the her head reaches only to the crown unlike the male on which the red feathers extend from the nape to the beak.

Later in the week, a small, blue-gray Sharp -shinned Hawk (Accipiter striatus) shot by me on the western side of the woods.  As I’d crested a rise, this little woodland hawk, the smallest hawk in North America, had spotted me from a low limb, immediately leapt into the air and flew off with consummate skill among the tree limbs.  Here’s a photo of one scoping out prey from a bush in a previous winter.  Sharp-shinned hawks often pounce on mice and, unfortunately songbirds,  from low branches.  So I may have thwarted a hungry raptor, who like all birds was trying to bulk up for the winter months.

With these hungry raptors hunting around the woods, the American Tree Sparrow (Spizella arborea), which seems to be the only sparrow around right now, hid within the protective branches of a bush. Pretty effective camouflage.

A flock of American Crows (Corvus brachyrhynchos) could be heard in the distance, too.  Crows frequently mob hawks, harassing them with dive-bombing and noise to drive them from their territories.  This may have been just late fall group behavior (left), but I have seen hawks and crows in conflict before in Bear Creek (right). (Rest your cursor on the photos for captions.)

The woods provided a couple of other fun moments.  A wary doe near Gunn Road stalked along behind the trees, but curiosity about the cameras always seems to seduce White-tailed Deer (Odocoileus virginianus).  They just have to turn and look.

And one of the fun natural features of the park showed up nicely in the snow the week before last – what I call The Mitten Stone. I forgot to include it in last week’s blog. Now that’s Pure Michigan, isn’t it?

The Forest:  Dabs of Color in the Brown-Gray Landscape

Mushrooms (the seeding parts of underground fungi), lichens and mosses did their part again this week to add bits of color here and there to the rather somber backdrop of late fall.  I’m no mushroom expert so no specific identifications here.  Does anyone know a reliable site? (Click on images to enlarge. Rest your cursor on a photo for a caption)

I’m a firm believer that there’s no bad weather for walking, just bad clothing.  Try a rainy walk at Bear Creek in a sturdy raincoat and good boots – or with an umbrella –  and see how the moisture saturates the colors.  Or let the frost prickle your nose on a super cold morning.   A long walk or a short stroll, you’re bound to discover something worth the trip.

THIS WEEK AT BEAR CREEK: From the Sedate Colors of Late Autumn to Winter White

Cam in red winter coat BC
Blog post and photos by Cam Mannino

I’ll be the first to admit that wildlife was a bit quiet this week at Bear Creek Nature Park. The early part of the week was typical of November – brown and gray.  So I went searching for bright colors or interesting shapes and found a few native plants, lichens and mushrooms adding  what designers call “visual interest” to the landscape.  And then suddenly at the end of the week, winter arrived!  I’m enough of a child to still love the first snow – and what a snowfall! Early Saturday morning, I walked through a silent Bear Creek – even my footsteps were muffled by the snow. Walking over an hour across the fields and through the woods,  I heard the twitter of one Tree Sparrow and a Chickadee’s call, a Blue Jay warning the world of my presence,  the soft “chip” of one Northern Cardinal and the inevitable low grumble of an American Red Squirrel annoyed by my passing – but I saw none of them as they huddled away from the swiftly falling snow.  So this time our weekly virtual stroll through Bear Creek travels quickly from late autumn to early winter.

Late Autumn:  A Search for Colors and Shapes

Falling bur oak leaf

Late November is a tough season to love.  The vivid colors of October drain away as the sap flows down into the tree roots and the landscape turns gray and brown.  Birds are more scarce and harder to see as they twitter softly inside bushes or high in the trees. Bird nests appear in the bare branches – like this shrunken sack over the Playground Pond, the remains of the nest of a pair of Baltimore Orioles (Icterus galbula).  This spring I saw the yellow/orange female’s tail protruding from the top as she fed her young in the nest below. Her brilliant orange and black mate helped out, making frequent trips to the nest.  Look at that lively little home now!

So I decided I’d keep my eye out for any color or interesting shapes that I could spot in the park.  Unfortunately, a lot of the color comes from invasive plants!  After all,  one of the reasons they escaped from people’s gardens is that they provided color late in the year.  But I wanted to see what our native plants could provide.

The Staghorn Sumac (Rhus typhina) still had bright scarlet plumes on the western slope.

Staghorn Sumac still red at the bottom of the western slope.

And everywhere the red leaves of Common Blackberry (Rubus allegheniensis) broke the tawny sameness of late autumn.

Common Blackberry
Common Blackberry adds a smattering of red to the brown landscape of late autumn.

All over the park, small trees bravely waved their large leaves which they’d used to soak up as much summer sunshine as possible.  This tiny Black Oak (Quercus velutina) may someday be a huge, spreading tree since it found a place in full sun on the western slope.  Its crimson leaves stood out in the field of dried Canada Goldenrod (Solidago canadensis) and Queen Anne’s Lace (Daucus carota).

Tiny black oak tree

A ball gall on what appeared to be another blackberry bush took on the dark reddish sheen of its host.  Galls occur when insects lay their eggs in plant stems and the plant grows around it,  providing a relatively safe place for the insect that will emerge in the spring.

Reddish gall
A ball gall on what I think is a blackberry bush houses the larva of at least one insect, possibly more, until spring.

Near one of the wetlands, the bright red and green of a moss-covered log caught my eye.  Dr. Ben VanderWeide, Oakland Township’s Stewardship Manager,  tells me, “Mosses are really cool … The green part that we always see and call “moss” is actually the “gametophyte generation” of mosses  –  the generation with one copy of DNA that produces “gametes,” sperm and egg. When it rains, the sperm swim through the film of water on the mosses to reach an egg in the tip of one of the green mosses. After fertilization of the egg, a new plant grows into the “sporophyte generation” (red filaments in the picture below), which has two copies of DNA and produces spores. The spores then spread about and germinate to grow into new carpets of green moss.”

Moss on a log green and red
Moss on a log. The green generation of moss produces next generation – the red filaments, that produce the spores which grow into more green moss.

Dr. Ben continues. “So what you see in this patch of moss is actually two generations – the green moss carpet that one has one copy of DNA, and the red filaments are the sporophyte offspring that have two copies of DNA. ”  I think that’s pretty cool, too. I’ve come to appreciate these bright red and green patches of moss in the austere seasons of the year, early spring and late fall.

Near the Marsh and in the Woods,  Some “Visual Interest”

When I entered the woods, color was even harder to find.  A rich brown acorn with its green top and rotund shape provided some visual relief among the wrinkling surfaces of fading fallen leaves.

Acorn
The rich chestnut brown of an acorn adds a bit of visual interest to fading brown leaves on the trail.

Though pale in color, I like the filigree of lichens and fungi that become more evident as the colorful flowers fade.  Lichens are sometimes confused with moss, but they are not related. In fact, lichens aren’t plants; they are a distinct form of life!  According to Wikipedia, they are composite organisms that arise when algae and/or cyanobacteria live symbiotically among fungi filaments. They don’t have roots like plants do.  Like plants, however, they produce the algae or cyanobacteria partner that produces food for the lichen through photosynthesis using sunlight, water and minerals.  Lichens may appear on plants, wood or rock, but they are not parasitic.  Pretty mysterious life form, really!  Here’s a lacy-looking one that is referred to as “foliose” because its structure looks like leaves. It’s on a railing at the southern marsh deck. And that yellow you see behind it is another lichen, a powdery one whose structure is referred to as a “leprose lichen.”

Lichen
A lichen does not have roots and is not a plant,but rather is a special composite life form that, like plants, is capable of photosynthesis. Both the white one in the foreground and the yellow spots in the background are types of lichen.

“Mushrooms,” are the fruiting bodies of  fungi that emerge from wood or soil and carry the spores for reproduction.  Fungi  form a distinct “kingdom” in nature, not related to plants, animals, bacteria, etc. I saw two forms of one broad category on this walk, the “polypores.”    Here are some polypore fungi on a snag  (standing dead tree) near the southern marsh. According to Wikipedia,  “Through decomposing tree trunks, they [fungi] recycle a major part of nutrients in forests.” They are the first step in a food chain: fungi process the wood cellulose, insects and invertebrates eat the mushrooms and birds and larger animals eat the insects and birds.  Fungi also soften up dead wood so that woodpeckers and others can make holes for nesting or winter shelter.  Nothing is wasted in a well-functioning ecosytem, eh?

Polyphore fungus

I’m always intrigued by how Shelf Fungi, another kind of polypore, form ruffles on the edges of sawed logs.

So the early part of the week at Bear Creek was still brown leaves underfoot, graying blooms of summer plants dropping their spring seeds in the Old Fields and pale mushrooms and lichen taking shape on old wood throughout the Oak-Hickory forest.

And Then Suddenly, Winter!

On Saturday morning, the snow began falling fast, like rain, cloaking Bear Creek’s Eastern Old Field in white.

The plumes of Canada Goldenrod began to droop a bit under the weight of the snow.

A few red bright red leaves wore a bright cap of snow near the marsh at the southern of the eastern Oak-Hickory forest.  The Common Blackberry from earlier in the week now has snowy accents.

The woods were, as poet Robert Frost put it,  “lovely, dark and deep.” And so quiet.  Not even a squirrel moved. Only an occasional muffled bird call reached me.

On Saturday morning, the woods were, as poet Robert Frost put it, “lovely, dark and deep.”

To borrow again from Frost, perhaps you too can bundle up and experience “stopping by woods on a snowy” morning during the hectic holiday season that begins this week. Caught up in the glitter and bustle of a busy season, the woods and fields offer serenity, quiet, beauty – a soothing space in which to breathe and find your bearings.  Have a wonderful Thanksgiving!
