THIS WEEK AT BEAR CREEK: Birdsong, Blossoms, Babies-Spring!

Spring Beauties
Tiny spring beauties find any sunny spot in the dappled light of the woods to show their delicate faces.

Sunlight is dappling the Oak-Hickory forest at Bear Creek. Tiny Spring Beauties (Claytonia virginica) shine pink and white wherever thin spring sun touches the forest floor. Migrating birds, here for a brief stop before moving north, hop from limb to limb in the treetops, searching for a meal. Some of our summer visitors are exploring for nests around the forest’s vernal pools while others are settling in around the ponds and among the twigs and vines in sunny areas.

A few butterflies and moths flutter through open fields, keeping us company as we walk. Springs bubble up out of the ground and a stream flows through the woods toward the marsh. The haze of green moves up from the shrubs into the trees. In the woods, in marshes and wetlands, in sunny meadows – at last, it’s really spring!

Spring in the Woods

During the night, migrating birds are riding the south wind, finding their way back to Bear Creek.  A busy group of Yellow-rumped Warblers  (Setophaga coronata) chatted and fluttered in the greening forest. They’re on their way north to court and breed among the conifers farther up in Michigan. Some go as far as Hudson Bay or eastern Alaska. Here they’re stocking up on protein for the flight, finding little insects on the branches. Later, in the trees near the Snell marsh, I got a shot of one showing his eponymous “yellow rump” patch. (Click on photos to enlarge; hover your cursor for captions.)

Farther into the woods, near one of the vernal pools we monitored a few weeks ago, two Wood Ducks had arrived from the south and were checking out possible nest holes 25-30 feet up in a snag (standing dead tree.) They prefer the larger holes left by fallen branches. Wood ducks have strong claws on their feet to grasp branches and bark. Later, their 3 day old ducklings  will jump down from those heights into the leaves below unharmed to join their mother foraging in a nearby pond as  seen in this 1.5 minute Youtube video from a BBC documentary.

Down in the vernal pool, beneath the Wood Ducks, stood a graceful, small tree covered in white blossoms, a Juneberry or Serviceberry (Amelanchier sp.).  This native tree produces small fruits that are much beloved by birds and other wildlife.

Plentiful spring rain topped up the vernal pool and a few Wood Frogs (Lithobates sylvaticus) began to sing again.  Mostly, though,  they seem to have found their mates and deposited their eggs on vegetation under the water.

Likewise, the salamanders have finished producing those huge bundles  of eggs that were in the last Bear Creek blog. These nocturnal creatures are now back under logs nearby, waiting to come out and feed at night. Here’s what I think is a small Spotted Salamander (Ambystoma maculatum) that we found under wood in a moist area near a vernal pond.

3 bloodroot
Bloodroot blooms for only 2 or 3 days in early spring and all over Bear Creek’s wood this year.

Under the budding branches of taller trees, all kinds of native plants are finding their way into the pale sunlight. The sunny faces of  Bloodroot (Sanguinaria canadensis) shown in the last Bear Creek blog (left) have finished blooming. But all over the woods you can see their cloak-like leaves which unfold after the flowers drop their petals. In the center, stands the Bloodroot’s “fruit” which now contains its fertilized seeds.

Seed pod of Bloodroot
The fruit capsule of a Bloodroot after the petals have fallen from the flower.

As the tree canopy fills high above, the Bloodroot’s stalk will continue to grow until it forms a little umbrella over the fruit. Eventually the seed capsule will swell and burst, dispersing tiny brown seeds for next year’s crop to be carried underground by ants who relish the elaiosome, a parcel rich in oils and proteins, attached to the seed.  This was a great year for Bloodroot. Successive prescribed burns may have really benefited this little woodland flower.

May Apples (Podophyllum peltatum) are living up to their names. Their umbrella-like leaves shelter a round green bud that resembles a tiny apple. It will bloom into a creamy white flower in a few weeks, still hidden beneath the leaves.

The bud of a May Apple does look like a tiny apple hiding beneath the umbrella like leaves.

An inconspicuous little plant called Pennsylvania Sedge (Carex pensylvanica) is just completing its bloom all over the forest. It appears to be little clumps of grass, but this time of year, this sedge blooms with a little yellow flower. The papyrus that ancient Egyptians used was made from a member of the sedge family.

Pennsylvania Sedge looks like clumps of grass in the forest, but is not a grass. It blooms yellow this time of year.

In moist places in the woods, an old friend appeared this week. Jack-in-the Pulpits (Arisaema triphyllum) produce bright red cones of berry-like fruit in the late summer and fall.

A small Jack-in-the-pulpit appeared in the woods near Bear Creek marsh.

At the edge of the wood, where it meets the field or the marsh, one of my favorite summer visitors has arrived. The Rose-breasted Grosbeak (Pheucticus ludovicianus), with the striking rosy red patch on his white chest and black and white patterned back, sings at the forest edge near the marsh and the pond. This one hid in a bush when he saw my camera – but kept singing!

And what a song! Here’s a recording in Bear Creek by my friend, Antonio Xeira from the Xeno-cantu website . (Be sure to turn up your volume.)

Here’s bit clearer photo from our home feeder.

Each red patch on the chest of a male Rose-breasted Grosbeak is different so it’s easy to tell one from another.

Some flowers seem to be happiest at the forest edge, too.  Like the shy Common Blue Violet (Viola sororia). Such a pretty little face.

Common Blue Violet often appears where the trail meets the edge of tall grass or the woods.

Approaching the pond as you come out of the eastern woods, you begin to see and hear a small stream flowing toward the marsh.  It’s most apparent under the boardwalk at the eastern edge of the Center Pond.

Stream from C Pond to marsh BC
A stream fed by the spring in the Center Pond runs east toward the marsh.

That little stream joins with ground water rising to the surface in the marsh and eventually flows under Gunn Road at the northeast corner of the marsh – becoming the park’s namesake, Bear Creek! I love the sound of running water after a frozen winter!

Spring in the Marshes, Ponds and Vernal Pools

There are babies down near the water. Four young Canada Goose goslings (Branta canadensis) paddled and bobbed between their parents as they surveyed Bear Creek Marsh.

And three small Painted Turtles (Chrysemys picta)crowded together on the tip of a log after rain made the water rise in the Center Pond. Space in the sunshine was at a premium!

These young Painted Turtles found only a tip of a log to bask on after heavy rains.

High above the marsh near Snell Road, the air was full of newly hatched midges and Barn Swallows (Hirundo rustica) swooped back and forth with their mouths wide open gathering them in. Their ruddy breasts caught the evening light at dusk one night and shone like copper. They were much too fast and high for a good shot.  So here’s a link to see one at the Audubon website.

Approaching the Center Pond at a distance one early evening, I saw a Great Egret drifting down to the water. I hurried along with my camera, but a very nice couple, walking and talking, scared him up just as I put the camera to my eye!  Drat. So here’s one of my favorite egret photos from another year. I’m glad to  know they’re still at Bear Creek since I missed them last year.

Spring in the Meadows

While near the Center Pond, keep an eye out for another summer visitor, the Eastern Kingbird (Tyrannus tyrannus), a feisty bird who harasses much larger birds that enter its territory – even hawks and herons!  According to the Cornell lab, “They have been known to knock unsuspecting Blue Jays out of trees.” The Kingbird’s dark head, upright posture and the white tips on its tail make it quickly recognizable. This flycatcher spends the winter eating fruit in South American forests.

Out in the eastern meadow one morning, a Tree Swallow (Tachycineta bicolor) sang its wonderful liquid song next to the nesting box at the top of the hill. I didn’t see a mate, so he may have been trying to attract one to that suitable home. This photo was taken an hour later as another one swooped for midges above the Playground Pond. I love the distinctive liquid gurgle of their calls.

In the meadow that morning, a Song Sparrow  (Melospiza melodia) had found a small tree near the Tree Swallow. He stood at the very top, threw back his small head, and sang!

The Chipping Sparrow (Spizella passerina) is a summer visitor who spent the winter in either Florida or the Caribbean. This little sparrow has a rusty brown cap and snappy black eye stripe and white supercilium ( strip above the eye).

The Chipping Sparrow is small and a very snappy dresser.

Some describe its chipping song as sounding like a sewing machine.  Below is another recording at Xeno-cantu by my friend, Antonio Xeira.

Tiny early spring butterflies and moths spin and float along the trails, as caterpillars trundle slowly in the grass below. Here again is the caterpillar of the Virginia Ctenucha Moth but this time I saw it upside down so that its red feet and white tufts were more apparent than its dark upper side with its two faint yellow stripes seen in an earlier blog.

You may remember the Spring Azure butterfly with its gray underside from last week’s post about Draper Twin Lake Park.  Amazingly, at Bear Creek this week, one settled for a quick moment and I got to see the lovely lavender blue of the upper surface of its wings, which I normally see only as a spinning blur when its flying.

The blue wings of a Spring Azure are normally seen only in flight. When their wings close, they are gray with faint blue stripes.

On the trail last week, my husband spotted this tiny moth with about a one inch wingspread. At first I thought it was some sort of fancy fly, but after some research, we learned it was a Grapevine Epimenis Moth (Psychomorpha epimenis). This tiny moth’s caterpillar, as its name applies, uses various grapevines as a host plant.  According to Wikipedia, “The larva [caterpillar] makes a leaf shelter in new foliage by taking the leaf edges, pulling them upward and then tying them together with silk.”

The tiny Grapevine Epimenis Moth breeds once a year and its caterpillars use grape vines as a host plant.

During the recent prescribed burn at Bear Creek, Ben discovered a small spring bubbling out of the earth in the eastern meadow. There’s something magical about water flowing up out of the earth, only to sink and disappear again.

The native plants transplanted to Bear Creek last year from a generous donor are beginning to bloom near the pavilion. The golden Wood Poppy (Stylophorum diphyllum) shone like a little sun of its own in late afternoon light. And another lovely native, new to me, is the wildflower on the right with the unfortunate name of Bellwort (Uvularia grandiflora).  The leaves seem to droop like the lovely flower, though Ben tells me, once blooming is over, they expand, fill out and look lovely for the rest of the summer!

 

Final Note:  Closed Trail

Some of you may have noticed that the trail that wound around the wetland below the south hill is closed.  Five years ago when a management plan was created for Bear Creek, Plantwise, who studied the park and wrote the plan, recommended reducing trail density in the park so that the wildlife would have larger portions of undisturbed habitat.  Also, being near the marsh, the newly closed trail is often soggy with standing water, which which means wet feet for hikers, deep ruts made by bikers and headaches for mowing crews. It also means that when those activities take place on the trail, there’s erosion and the possibility of increased sedimentation in the marsh. As Ben said, “Moving the trail away from the wetland may allow the woodcock and some other birds to breed successfully near that little wetland, instead of using it as a temporary stopover on the way to better habitat.”

So if you start down the south hill below the benches, just take a left into what I’ve always called “the tunnel of trees” and you’ll come out on the south side of the meadow that’s east of the Center Pond.  From there, you can skirt the wetland from the other side and still see the birds at the edge of the marsh and listen to their songs from a nice dry trail. Dry feet and more birds.  Sounds like a workable solution.

Spring All Over Bear Creek

So no matter where you go now in Bear Creek, spring asserts itself. If you settle on a quiet bench by the water, climb a rolling woodland trail or stroll through a sunlit meadow, spring will be singing, flying, fluttering and swimming by and around you. Relish it while it lasts!

THIS WEEK AT BEAR CREEK: Shrimp, Clams?? Yes! Plus Plenty of Spring

Quite a week at Bear Creek!  It began with 3 inches of snow at  30 degrees and ended at 70 degrees and sunshine! I began the week by joining Ben and two other volunteers (Catherine Hu and Antonio Xeira) in monitoring the creatures that live in our vernal pools – the wetlands that fill in the spring and mostly or completely dry by middle or end of the summer. I’ll be sharing both my photos this week and, with his permission,  the photos of Antonio Xeira, an avid birder from Portugal and a fellow lover of the natural world.

It turns out that Bear Creek’s vernal pools are teeming with life!  And new life began to assert itself in the rest of the park, too,  as the weather warmed. The first woodland flowers thrust out of the earth,  a few more migratory birds rode in on the wind, butterflies spread their wings in the sunlight, turtles basked and swam while the frogs  sang and salamanders left floats of eggs in the vernal pools. Finally, on a perfect spring Saturday, humans appeared on the playground lawn enjoying the spring sunlight with their fellow creatures.  A lovely week.

Who Knew Bear Creek Hosted Shrimp and Clams?

Antonio and Catherine OT0002
Volunteers Catherine Hu and Antonio Xeira examine their finds from a vernal pool.

Michigan Natural Features Inventory is leading a project to map and monitor vernal pools, something never done in Michigan before. Since these wetlands dry up for part of the year, they are particularly vulnerable to being filled in. But scientists are finding that vernal pools are “biodiversity hotspots” of the forests. Late fall or early spring flooding of these pools stimulates dormant creatures to awake and others to hatch as the water level rises. The “indicator species,” the ones normally present in a vernal pool, are, among others,  wood frogs, fairy shrimp,and a variety of salamanders.  We sampled four ponds and found evidence of these species.

Fairy Shrimp (Order Anostraca) are .5 to 1.5 inches long, swim upside down and look like a tiny version of the shrimp sold at the seafood counter!  According to the website of the Vernal Pool Association, their sets of 11 leaf-like legs do several things – propel them through the water, gather food (algae, bacteria etc.), and take in oxygen from the water.

Of course there are other small creatures in these ponds too – tiny Fingernail Clams (family Sphaeriidae), mosquito larvae and water beetles that row around with their front legs like oars! (Click to enlarge; hover cursor for captions)

Wood Frogs (Lithobates sylvaticus) love these ponds. We found brown ones and one tiny rust-colored one underneath a log. They come in varying shades of brown and, according to Wikipedia,  some are able to change their shade! (Both photos by Antonio Xeira)

The salamanders had already mated, laid their eggs in the water and disappeared under logs or leaf litter. But their egg sacks, attached to twigs, were pretty impressive!  Ben thinks the larger egg masses are Spotted Salamander (Ambystoma maculatum), with Blue-spotted Salamanders (Ambystoma laterale) laying smaller egg masses or individual eggs.

Meanwhile in the Sunshine…Birds!

More migratory birds are passing through to cooler climes or coming to spend their summer with us. One late afternoon on the far side of the Center Pond, I watched a Belted Kingfisher (Megaceryle alcyon) perch, watch carefully and suddenly dip down into the water with a rattling call.  Belted Kingfishers excavate 3-6 foot bank-side tunnels for nesting which slope upward to keep out water. Fossils indicate that they have graced ponds for 600,000 years! This fellow was a male; a female has a rust-colored belt across her belly, making her one of the few female birds who are fancier than the males.

Belted Kingfisher 2

The Kingfisher will spend the summer with us, as will the Northern Flicker (Colaptes auratus).  These beautifully spotted birds can be identified  in flight by a flash of white on their rump.  They’re high in the trees now, probably searching out nest holes. But since ants and beetles are a favorite meal, you can spot them poking their long beaks and barbed tongues into lawns or trails too.

An unusual posture for a flicker who normally uses its barbed tongue and long beak to probe the ground for ants and beetles.

A tiny migrant arrived this week too, the hyper-active Ruby-Crowned Kinglet (Regulus calendula). With a constantly flicking tail, these restless birds move from branch to branch, rarely alighting for more than a few seconds. This one is just passing through on its way to breed somewhere in Canada.  Its “ruby crown” only appears when it’s excited so I guess this one felt relaxed, despite its hyper behavior.

A pair of Eastern Phoebes (Sayornis phoebe) hung out near the kiosk at Gunn Road. They were clearly checking it out as a possible nest site. Once she starts laying eggs, however, the female will chase this male away from her mud-and-grass nest.

I don’t often see American Goldfinches (Spinus tristis) at Bear Creek during the winter, though they stay in the area.  My theory is that they’re all at neighborhood thistle feeders! But admittedly, they’re easier to spot now that the males have donned their bright yellow summer feathers.

Flowers and Butterflies – It’s Definitely Spring!

Most years, I don’t see any woodland flowers until later in spring. The earliest to emerge are usually Spring Beauties (Claytonia virginica). But right now at Bear Creek, those lovely little flowers have only their leaves coming out of the ground in the dappled light of the woods.  But another of my early spring favorites, with the un-poetic name Bloodroot (Sanguinaria canadensis), is blooming along the western side of the Northern Loop. Notice how the flowers arise before the furled leaf below has opened – unusual in plants. The leaf will make a circular cloak around the flower once it’s fully open.

Blood root BC
The leaves of the Bloodroot unfurl after the flowers appear, eventually making a round cloak around the blossom.

Two butterflies fluttered over my shoulder on Saturday. Both of them spent the winter months as adult butterflies, hibernating in a frozen state under loose bark or in tree cavities. Mourning Cloaks are frequently the first butterflies out and about  in the spring which means they start the mating process earlier and have more broods than many migrating butterflies or ones that hatch in the spring. This one quickly winged its way to the Oak-Hickory forest – perhaps hoping for oak sap to rise soon and fill wells made by sapsuckers.  Sap is one of its favorite foods. Nice winter camouflage, eh? It looks like loose bark, especially with its wings closed. The Mourning Cloak has blue spots on it wings when they are open.

A small Eastern Comma (Polygonia comma) fluttered around me, landing on the trail. It also favors tree sap and spends the winter in frozen hibernation as an adult. The one I saw Saturday was tiny, restless and hard to photograph but it was still wearing winter colors – hindwing mostly orange with black spots (in photo at left). In the photo below, taken in a previous June, a summer-form Eastern Comma sports dark hindwings.

Basking Feels So Good in the Spring!

A Garter Snake (genus Thamnophis) had climbed onto a small tree in one of the vernal pools we monitored last Monday and dropped into the water as Antonio, one of the volunteers, approached. No doubt it was interrupted while trying to soak up some sunlight after frigid Sunday weather.

Fourteen Painted Turtles (Chrysemys picta)shared logs in the Center Pond, soaking up the sun of the first really warm day. Like snakes, turtles are reptiles which can’t regulate their body heat except through activity. So most warm days turtles stick out their heads, necks and legs to capture the sun’s heat on their extremities as well as their dark shells.

I saw my first Snapping Turtle (Chelydra serpentina) on Saturday as it cruised the marsh. It was feeding below the water with its long neck and then poking its head out for a breath of air. It must feel great to eat and swim after a long winter under the ice.

And human denizens of the park came to Bear Creek on Saturday to eat and bask in the warm sunshine, too. This family (whose name I unfortunately forgot to get!) graciously allowed a photo of their picnic on the grass with a lovely little human in a big hat to protect her from the spring sunshine.

So much life in this 107 acres, eh? Within the shady vernal pools, on logs at the Center Pond, on bare tree limbs, in the grass on the edge of trails and on the green carpet of  the playground, the park hummed with life by the end of the week. After a white-and-black, silent winter, the color and song of spring greet us like a warm smile. I hope you’ll be there, too,  smiling back.

This Week at Bear Creek: Bear Creek Begins to Bloom

Look for this feature early each week! Cam Mannino shares her latest observations, photos, and inspirations from Bear Creek Nature Park. Don’t forget to check out the Preview of Coming Attractions at the bottom of the post to see what you should be looking for in the coming weeks. Thanks Cam!


April 12-18: Bear Creek Begins to Bloom

This week the earliest woodland flowers took advantage of the pale sunlight filtering through bare branches and bloomed. Please help children understand not to pick flowers in our parks; we want them to prosper, seed and keep spreading!

The first to arise, as usual, were the native Spring Beauties (Claytonia), thrusting slender, grass-like leaves through the soil beneath large trees, followed by delicate white flowers with fine pink stripes. Look for them on the western edge of the path through the western woods.

Another early riser is our native Blood Root (Sanguinaria canadensis), named for its use as a dye by native basket makers. This elegant little plant emerges wrapped in an almost circular leaf cloak, after which the small, white flower with a bright yellow center opens to the sun and the leaf unfolds. I tracked its progress over 3 days under a large tree left of the path near the Gunn Road end of the marsh. A large patch of Blood Root also appears every year among fallen trees on the western side of the long loop behind the center pond. But be quick; these very early spring flowers usually last only a few days!

The more odiferous and sturdy native, Skunk Cabbage (Symplocarpus foetidus), nosed its way out of marsh mud at the southern edge of the western woods. Look down from the eastern side of the bridge built there for us by an Eagle Scout. If you get too close, whew! They do like to make a stink each spring but that’s how they attract fly pollinators and discourage would-be foragers!

Over in the marsh, two fighting Muskrats (Ondatra zibethicus) staged a splashing chase scene for me, but I was only able to catch a photo of one swimming away in its blue wake.

A day later it was turtle fest again. Five Painted Turtles (Chrysemys picta) basked on a log in the center pond, lined up by size as if they were the VonTrapp family!

And the same day, a large Common Snapping Turtle (Chelydra serpentina) cruised the marsh, eating underwater plants, its long neck stretching up periodically for air. Watch for what looks like a lump of mud moving slowly in the water, with the turtle’s beak-like snout emerging separately just ahead. Like this:

Two days later on the large loop, I very carefully approached another snapper, which was probably seeking a place to lay eggs. She wisely sought a better location since there was no disturbed earth the next day. Don’t get too close! These big turtles are crabby on land and can quickly extend their necks which can be as long as their carapace. They snap with powerful jaws, because unlike other turtles, they are too big to pull into their shells. The snapper’s ancestors lived at the time of the dinosaurs and they look it, don’t they?

The female Red-winged Blackbirds (Agelaius phoeniceus) have now joined their flashier mates in the marsh.

A Red-bellied Woodpecker (Melanerpes carolinus ) drummed for a mate nearby. The males are red from the nape of the neck to the bill like the one below. The females have a red nape patch that stops at the back of the head. Not to be confused with the Red-headed Woodpecker (Melanerpes erythrocephalus), like the cartoon Woody, whose neck and head is completely red and whose plumage is very different.

Previews of Coming Attractions!

Let’s see if these Trout Lily leaves (Erythronium ) near the Gunn Road entrance produce any beautiful yellow flowers. It’s been years since they have, but maybe the prescribed burn will help them out this year. It bloomed after a previous burn!

A May Apple (Podophyllum) sprout and drooping unopened leaf emerged in a sunny spot next to the path. In May, a white flower will bloom shaded under the fully open umbrella leaf, to be followed by an inedible “apple.”

Sunday morning, a North American Raccoon (Procyon lotor) snoozed in this tree on the western-most path through the woods, only a small slice of fur visible at the bottom of the hole until my camera clicked. Keep watch here – by the end of May, baby raccoons may clamber around inside the hole as they have most years. I recommend whispering and staying on the path with binoculars or she and the young will disappear farther up inside the hole.
