I dropped in on Bear Creek Nature Park multiple times in April and early May, watching nature’s slow-but-steady journey into spring. After a difficult year, seeing nature renew itself felt especially reassuring – a useful antidote to the leftover doldrums of 2020.
This week along with my own photos, I’ll be including many by other residents who generously agreed to share their amazing photography. Regular blog readers will remember Bob and Joan Bonin who have previously lent me their amazing photos. And recently, I made a new photographer acquaintance, Paul Birtwhistle, who explores our parks with his camera and his peaceful dog Stanley. All three of these local photographers are blessed with eagle eyes and exceptional photographic skills as you’ll see below. I thank them all for their willingness to let me share their finds with all of you. Believe me, you’re in for a treat!
Nature Begins to Stir in the Cool Gray of Early April
It seems that each year as I enter the park in early spring, the first song that falls from the canopy is that of the Song Sparrow (Melospiza melodia.) Their song, which can vary a bit geographically, most often starts with a few short notes, followed by a melodious trill and finishes off with a buzz. A streaky, little brown male with the typical spot on his breast perched at the top of a tree, threw back his head and belted out his song to woo any willing female within range. This year’s vocalist was much too far away for a decent photo, but here’s one from an earlier spring at Bear Creek Nature Park.
During the bird walk in the first week of April, Ben spotted a Pileated Woodpecker (Dryocopus pileatus) posing right at the tip of a snag near the park entrance. It was so high that it only made a silhouette against a gray spring sky, but I tried to take a photo anyway. I love that big red crest! These woodpeckers make their rectangular nest holes high in either snags or live trees in the spring and then make lower ones in the fall as shelter from winter winds. I’m going to keep an eye on that snag!
This Downy Woodpecker (Picoides pubescens) looked a bit chilly as it huddled against a bare branch while searching for frozen caterpillars or insect eggs.
On the way down the Walnut Lane toward the Center Pond, I spotted a Hazelnut Bush (Corylus americana) in bloom. The golden catkins are male flowers. The slightest breeze sends their pollen wafting over the tiny, pink female flowers that barely peek out from the end of the twigs. I’ll be curious to see if it produces any hazelnuts on its thin branches. [Click on photos to enlarge.]
The chuckling of Wood Frogs (Lithobates sylvaticus) in a vernal pool invariably greets me as I step into the woods in early April. These little frogs float on the surface, occasionally kicking their legs to move about as they call for a mate. Consequently, they’re much easier to spot than the tinier chorus frogs who lurk under the edges of logs or aquatic plants. After having frozen and thawed unharmed throughout the winter, these masked frogs move toward the pools in early spring. Vernal pools dry up in the summer, which means Wood Frogs can lay their eggs without fish making a meal of them. This time, a log seemed to provide a handy place for the frogs to rest between unsuccessful bouts of floating and chirping; I sympathized as a former wallflower myself!
A pair of Canada Geese (Branta canadensis) cruised the far end of the vernal pool. At one point, the slightly larger male performed some amazing preening moves. Or maybe he was posing in an attempt to flirt. If so, his partner doesn’t seem too impressed.
On the way back from the Wednesday bird walk at Bear Creek in early May, my photographer friend, Bob Bonin, got a wonderful shot of a Black-capped Chickadee (Poecile atricapillus) excavating a promising nest hole. Look at that beak full of wood! Chickadees are cavity nesters and will create a nest in soft wood if they can’t find an existing hole that suits them.
Birds and Blossoms as the Woods Turn Green in Late April
Spring turned from brown to green in the second half of April. Unseen in the night sky, millions of birds rode the wind north and some eventually drifted down into Bear Creek Nature Park. Many came here planning to raise young in the park. For others, it was simply a rest stop on their journey farther north.
The Avian Summer Residents
My new photographer friend, Paul Birtwhistle, got an amazing shot of a rarely seen visitor, the American Bittern (Botaurus lentiginosus). While Paul and his dog sat quietly on the far north dock of Bear Creek marsh, the Bittern stepped quietly out of the reeds near the shore. Bitterns can breed in Michigan so we can hope this one chooses our marsh. If so, perhaps one day we will hear their booming call that sounds like a low “gulp” coming through the cattails and reeds. Cornell Ornithology’s All About Birds website says that when this birds sees a possible threat, it may choose to assume its concealment pose, its neck elongated and its bill tilted toward the sky. Sometimes it even sways, trying to blend its striped body into the moving reeds. Cornell says the posture is so ingrained that they sometimes do it even when in the open as it was in our marsh. I’m glad Paul had this exciting moment and shared it with us.
Paul also saw a Sandhill Crane (Antigone canadensis) at the marsh and a male Wood Duck (Aix sponsa) cruising in a woodland marsh on the southwestern side of the forest. These birds both tend to spend the summer here to mate and raise their young. The Sandhills toss plant material into a mound, then form a neat cup in the center lined with twigs. Wood Ducks look for cavities high in the trees near water, using the hooks at the back of their feet to navigate on the tree bark. What great guests to host for the summer!
Every year we also act as hosts for the Tree Swallows (Tachycineta bicolor) in the nest boxes built by birder Tom Korb and installed by the Stewardship Crew. These iridescent avian acrobats will soar above our fields all summer, gathering insects in their open beaks. But in late April, they are busy within our boxes creating nests out of dry grass and lining them with white feathers. Paul caught a pair claiming a nest box on April 27.
In a tree near the nest boxes, a male Eastern Bluebird (Sialia sialis) surveyed the territory. He appeared to be keeping an eye on his mate as she gathered grass for her nest. Bluebirds will nest in boxes near our Tree Swallows from time to time, but they won’t tolerate another bluebird pair close by. Their sky blue eggs take twelve to fourteen days to hatch. A team of trained volunteers coordinated by our township Stewardship Specialist, Grant VanderLaan, monitor the nest boxes in several parks from first egg laid until the young fledge. The data are provided to Cornell University’s NestWatch program, a citizen science project. Some bluebirds stay with us all year ’round and others seek us out as the weather warms.
On April 24, Paul Birtwhistle spent a long time at the Center Pond listening to the kwirr call of the Red-bellied Woodpecker (Melanerpes carolinus) before being able to spot it. At last, he caught sight of the red crown and nape of a male’s head peeking out from a hole on the underside of a branch on the huge White Oak at the pond’s edge. Years ago near the Bear Creek marsh, I’d seen one of these woodpeckers sticking its head out of a horizontal, upside-down nest hole in an oak branch. It seems that these male woodpeckers excavate several nest holes in hope of giving their mate a choice.
According to the Cornell Ornithology Lab’s All About Birds website, one of the Red-belly’s options for nest hole placement is dead limbs in a live tree, which is exactly where this bird ended up. The holes are about 9-13 inches deep (or maybe horizontal in this case?) and the circular living space is roughly 3.5 by 5.5 inches. Pretty snug fit, I would think! Once the female has chosen her preferred hole, she lays her eggs on a bed of wood chips left from the excavation accomplished by both mates. Sometimes, the pair drill holes along the branch outside the nest hole to warn off other birds, a kind of “We claim this spot!” message. I hope this hole by the pond was chosen by the female.
Katri Studtmann, one of the stewardship summer technicians, gave me a heads-up to look for a Belted Kingfisher (Megaceryle alcyon) that she’d seen at the Center Pond. Of course, the Kingfisher saw me first as I came to the end of the Walnut Lane and took off. I saw her dive into the water at the far end of the pond, but she came up empty. Females, by the way, have one blue and one chestnut brown stripe on their breasts while the males have only the blue stripe.
Of course many more birds arrived at Bear Creek Nature Park last month than Paul, Bob, Joan or I happened to see, successfully record or share. But using the Cornell eBird lists created by participants on the April and early May bird walks, here’s another quick slide show of birds you might see or hear at our parks now if your binoculars can find them among the spring greenery! (The photos here are from previous years by me and others.)
All Eyes on the Warblers in May! Some Stay and Some are Just Passing Through
The big warbler migration began here in late-April with hearing or seeing the Blue-winged Warbler and the Palm Warbler. During the May bird walks at both Bear Creek Nature Park and Cranberry Lake Park, we saw many more of these tiny long-distance travelers. So keep your eyes open for small, colorful birds flitting about in trees or diving in and out of shrubs. You don’t want to miss these beauties who often arrive in the morning after riding a strong south wind during the previous night. Some choose to spend the summer here raising young. But others you’ll see below are only here for a few days as they rest up before heading north.
Under a Greening Canopy, Spring Blossoms Emerge in the Woods
As migrating birds arrive, the woodland plants seem to magically appear as the soil warms under the spare canopy of spring. Always the first to arrive are the spring ephemerals, like Spring Beauty (Claytonia virginica). This spring ephemeral blooms very early to catch the sun while the trees are bare, then quickly subsides as the shade increases above it. Bloodroot (Sanguinaria canadensis) does the same, but uses its leaf cupped below the blossom to preserve some warmth on cool spring days. Bloodroot leaves remain for some time after the petals of the flower have fallen.
In late April and early May, May Apples (Podophyllum peltatum) begin to form colonies under large trees and produce their shy flowers beneath the leaves. Jack-in-the-pulpits (Arisaema triphyllum) unfold in the woodland shade.
Delicate Wood Anemone blossoms (Anemone quinquefolia) nod above their frail stems in the moist shade near vernal pools. Nearby red sporophytes rise from green gametophyte moss. When mature, the sporophyte moss will release the spores which will disperse to start new gametophyte moss colonies.
And at the forest edge of the big loop, the white blossoms of American Dogwood (Cornus florida) turn their faces upward to the sun.
Resilience, Adaptation – and Song!
In April, I stood by a vernal pool listening to the chuckling song of Wood Frogs who had frozen and thawed repeatedly during a Michigan winter. This week I paused to enjoy the rippling melody of a Rose-breasted Grosbeak that rode the wind through the night to end up singing at the edge of a greening field. Life presents all of us mortal creatures with harrowing challenges. And still the wild ones sing, the leaves thrust through tough bark, and fragile flowers open their beauty to feed the world around them.
As part of the natural world, we too have faced repeated challenges to our survival, especially in the last fifteen months, haven’t we? Most of us have learned that we are more resilient than we knew. Like the little frogs, we have adapted to repeated and sudden changes. Like the birds, by moving on through the darkness we’ve reached the light of another spring. Like the plants, we struggled to bloom where we were planted, accepting limitations but still able to share what beauty we could muster with those around us who needed our nourishment. Despite the losses we’ve had and those we know will eventually come to all of us, let’s follow nature’s example and celebrate the fact that we’re here right now. Let’s belt out our own songs to a blue spring sky and relish being alive.

Oh, Camie – Surely one of my fave blogs! Birds and Spring wildflower, even frogs – oh, my!
Val and I starred (In our Mi Wildflower volume), all the wildflowers we’ve found on our 5 1/2 acres over that last 30 years. Now Joel and Bing are discovering NEW ones! – Last time I counted 77 different little miracles!!!! Glorious. But your research tells me much more than I dreamed! and the photos – superb! Here are our bragging rights re: birds this year (so far!)
Pileated, Downy, Hairy, Sapsucker (boo!), and Creamsicle. We have wee toads on our font lawn and frogs serenading along the river- brruupp, brruupp – (I invariably laugh out loud), Wood ducks, Mergansers, and our Bluebird box has been pre-empted by frantically busy Phoebes! This is the 5th year they raised several clutchs. We get to watch them fledge – a miracle of courage! Finally, our “Song Bird” is a-vsitin’ again – unbelievable music – we all stop what we’re doing and simply listen. We have not ID’d who it is – dang. He’s usually high up in a tall tree.
Sorry am so wordy – but your blog turned me on – so it’s your fault! Gerre
Wow, Gerre. You folks really do have so much to enjoy there! I’m glad you’re there, even though I miss your company. Thanks for the enthusiastic post! Not wordy, my friend. A sense of wonder is a beautiful gift.
Thanks, Bob. I had help from 3 terrific photographers on this one!
Wow,Cam,,What great photos and nature lessons.
