Cranberry Lake Park: Spring Music in the Wetlands

In spring, nature generously replenishes the multitude of Cranberry Lake Park’s wetlands. Besides the lake itself, shady woodland ponds and pools glitter through the trees along nearly every trail at Cranberry. All of which makes me happy, because being near water is the surest way to find wildlife and interesting plants.

I seek out wet places whenever I go visit our parks since so much goes on around wetlands. Right now, ferns unfurl and spring wildflowers emerge on the sunny or shady edges of trails. Birds sing and chatter from within or just outside of the wetlands, as they forage, perform for mates, challenge others for territory or simply celebrate the sun after a cold rainy night. Throughout the park on three spring mornings, glorious music kept me company as nature’s virtuosos joined in a  spring chorus.

After serious downpours, though,  it helps to know the trails well enough to avoid being confronted by a calf-deep small pond! Dr. Ben VanderWeide, our township Stewardship Manager, has kindly created a map of my meanderings at Cranberry Lake Park. This route generally can be done with dry or at least only moderately damp feet. So daub on a bit of bug repellent and don some waterproof footwear as we head out to the sights and the special spring sounds of rain-soaked Cranberry Lake Park.

Heading North Accompanied by Bird Song

The north trail from the farm site strewn with apple blossom petals

Seeing that the water on the short trail out of the parking lot was ankle-deep and impassible, I headed across the cut grass toward the red-and-white chicken coop that is part of historic Cranberry Lake Farm. I turned onto the trail that looked as if a wedding had just ended, as it was strewn with fallen apple petals. High overhead, the sweet, whistling song of a male Baltimore Oriole (Icterus galbula) celebrated the blue sky morning with a joyful noise!

A male Baltimore Oriole greeting the morning with his high, flute-like song.

Across the way, a bit further on, I paused to listen to a male Yellow Warbler (Setophaga petechia) repeating his quick “sweet, sweet, I’m a little sweet” song. He was deep in the greenery so I waited and watched. Finally I resorted to playing the warbler’s song on Merlin, Cornell Lab of Ornithology’s very useful bird ID app. I don’t use it often to flush out birds because it can stress them. So I played it only once. And out popped the Yellow Warbler to check out the competition.

A Yellow Warbler male pops out of the greenery.

He hopped about a bit for a minute or two and then went back into the greenery and continued to sing. I was relieved that he seemed to have decided that the bird on the app was no match for him!

Tracking West Across a Meadow

I turned left at the round turkey brooder building and headed back west toward the Shagbark Hickory Lane.  Oops – the trail was flooded here too, but luckily, the maintenance crew had set up a boardwalk along the edge which, though a bit askew, provided relatively dry footing.

Along the east-west trail nearest to the farm, a wooden platform provides dry footing after a night of rain.

As I walked into the meadow, I noticed a large insect bumbling about among the dandelions on the trail. I’m so glad I stopped for a closer look! A Snowberry Clearwing Moth (Hemaris diffinis) trundled its hefty body from one dandelion to the next. The non-native dandelions provided the nectar that morning, though I’ve seen Clearwings (there are two kinds around here) most often on native Bee Balm (Monarda fistulosa) when it blooms later in the summer. These moths, which look so much like bumblebees, fly during the day, but if they find a good nectar source, they can forage in the evening as well. So check out bumblebees on your flowers and see if you can spot one of these moths!

A Snowberry Clearwing Moth can easily be mistaken for an oversized bumblebee!

Dandelions were also being visited by a green florescent native bee. I’ve learned not to attempt identification of native bees. According to Doug Parsons, director of the MSU Bug House, you really have to be an expert who has both the insect and a magnifying glass in hand to positively identify them.But I do love to look for these small, solitary, native bees!

A native bee making the most of early season dandelions.

Wild bees hadn’t yet discovered the modest wildflowers of Wild Strawberry (Fragaria virginiana) when I saw these tiny blossoms down among the tall grasses of the meadow.  I imagine hover flies and bees will show up once a few more flowers emerge. If the plant is fertilized, it will set a tiny fruit which no doubt some bird or animal will get to before I do!

Wild Strawberries in the south meadow at Cranberry Lake Park

A Gray Catbird (Dumetella carolinensis) chatted its conversational song in the bushes at the back of the meadow. Catbirds held their loud “conversations” all over the park one morning, combining whistles, squeaks and bits of other birds’ songs. Finally this one emerged into a Wild Cherry tree (Prunus serotina) where I took a quick shot before he sailed back into the shrubbery to sing some more.

A Gray Catbird sang its long song full of trills, chirps, whistles and such from among the blossoms of a Wild Cherry tree in the meadow.

The vigorous breezes of a beautiful spring morning drowned out my recording of this male. But a Catbird I heard last year at Bear Creek Nature Park’s Center Pond will give you a feel for the long, complicated phrasing of its song. On this recording, Green Frogs (Rana clamitans) provide backup percussion from the water below!

By now regular readers know that I’m quite fond of the Eastern Towhee (Dumetella carolinensis) –  probably because its song was one of the first ones I learned to recognize.   A male perched in a small tree invited a nearby female to appreciate his rendition of  “Drink your teaaaaa.” She listened politely nearby. I was surprised to learn from Donald W. Stokes’ A Guide to Bird Behavior, Vol.2 that Towhees make their nests on the ground like many sparrows. Once the nest is built, both adults become more secretive. The male stays away until the eggs hatch. At that point, he returns to feed both his mate and the young and continues helping the female with caring for the young from then on. So look for them in spring before they start nesting!

A Trip Down Hickory Lane

An old farm lane lined with Shagbark Hickories runs near the western boundary of the park.

A wonderful row of Shagbark Hickories (Carya ovata) line the western edge of the park. I love strolling along this dappled lane. The ground is  mostly firm underfoot and birds dart back and forth across the trail, forage along its edges and sing from the wetlands and fields off either side. Each spring I try to resist taking another photo of the large, almost rococo design of the Shagbark’s leaf buds. I failed to resist again this year.

The elegant design of an opening Shagbark Hickory leaf bud.

Ahead of me, I saw a Gray Catbird shoot across the trail and disappear. But as I got closer, I had the chance to watch it balancing on a twig over a large puddle to forage repeatedly for some kind of insects or larvae in the water. Once it had gathered a number of whatever it was, it jumped in for quick dip, ruffled its feathers and took off again.

A Gray Catbird foraging for insects or insect larvae in a large puddle next to the Hickory Lane.

Wild Geranium blossoms (Geranium maculatum) added dashes of lavender along the shady lane – some still in perfect form, others having served as a meal for the larvae of some hungry insect. A little damage to a blossom or leaf can mean a well-fed caterpillar to nourish a hungry baby bird. So holes here and there on plants are fine with me!

Two other native wildflowers graced the shade of the Hickory Lane. A cold snap had just ended, so the Trillium (Trillium grandiflorum) looked a bit beyond its peak bloomBut the buds of Solomon Seal (Polygonatum biflorum) had just formed beneath its leaves when I lifted its stem for a peek.

An adult Eastern Chipmunk (Tamias striatus) zipped across the path and froze when it saw me. I snapped my photo of the crouching little critter and waited. It dashed off and disappeared down a hole.

An adult chipmunk who’d taken its  young out on a foraging expedition.

Just as I lowered my camera, three baby chipmunks came tumbling onto the path, jostling each other as they raced after their parent and dove down the same hole. I wish I’d been fast enough to get you a photo of the babies, but alas, no. But I’ll include below one of my favorite baby chipmunk photos taken at home a few years ago.

A baby chipmunk about the size of the three I saw dash into a hole on the Hickory Lane at Cranberry Lake Park

Several metallic green Six-spotted Tiger Beetles (Cicindela sexguttata) darted down onto the path under the hickories. They can commonly be found in patches of sunlight at the edge of wooded areas. Despite their ferocious name and appearance, they don’t bite humans unless we handle them, and even then it’s an unnoticeably mild pinch, according to Wikipedia. Small caterpillars, ants and spiders, though, find them ferocious predators!

The Six-spotted Tiger Beetle is iridescent green with six white spots around the bottom edge of its abdomen.

On the Trail to the Lake Accompanied By Birdsong and an Amphibian Chorus

In the center of the park, several trails converge in a small meadow.  The one that heads out from the Hickory Lane and east to the lake was my choice. In the short video below taken on a glorious May morning, I spun around slowly where the trails converge, trying to record the bright blue sky, the fresh greenery and the birdsong soundtrack that was making me smile.

The background music was partially provided by a robust male Rose-breasted Grosbeak (Pheucticus ludovicianus) singing his lyrical song that is similar to the Robin, but a bit sweeter. I wondered if he was establishing territory because I’d seen an older male singing nearby a few days before. I’m betting that the younger male’s elegant pink ascot and vocal ability won him the territory and a mate – unless experience counts with Grosbeak females. The older male looked like he’d seen a few seasons, but he was a vigorous singer as well!  [Correction!  The bird on the right is actually a male juvenile who has not yet finished molting into fully adult male plumage!  The telling field mark is the white eyeline and white feathers at the neck.   And the one the left is in his second or older year!   Thanks to Ruth Glass, local birding authority, who set me straight on this!   I’m learning all the time from readers of the blog!]

Near a wetland on the north side of the lake trail, I heard a quick song that I didn’t recognize. Ah! I spotted a small, bright yellow bird with a black mask and a fancy black necklace – the Magnolia Warbler (Setophaga magnolia). I actually heard two of these warblers on the way to the lake, but only one stopped hopping from limb to limb long enough to show me how beautiful he was. He’ll nest farther north in dense forests of spruce or hemlock.

The Magnolia Warbler actually nests in conifers and spends winters in the American south.

Deep within the shrubbery of every  moist area along this trail, I could hear the “witchedy witchedy” call of the Common Yellowthroat (Geothlypis trichas), but I have yet to see one this spring! I waited, watched, but no luck. I’m sure I’ll catch sight of one before long since Yellowthroats raise their young here. But for now here’s an earlier photo of another lovely masked bandit. I think he throws his head back farther than any other bird that I’ve seen – and his whole body vibrates with the song!

A Common Yellowthroat singing “witchedy, witchedy, witchedy” from a shrub near a wetland.

Warblers are challenging subjects for us amateur photographers. They’re tiny, they rarely stop to pose and they arrive when the trees are leafing out! So I was happy to catch a quick photo of a Black-and-white Warbler (Mniotilta varia) as he busily spiraled around a trunk near the lake. It’s easy to mistake this little bird for a White-breasted Nuthatch (Sitta carolinensis) or even a Brown Creeper (Certhia americana) as they circumnavigate trees. Theoretically, this little warbler breeds here, but I’ve only managed to spot one during spring migrations.

A Black-and-white Warbler spirals around a tree searching for insects with its slightly curved beak.

As I approached the lake, I heard an amazing chorus of amphibians singing.  It wasn’t any frog song that I recognized,  so I was puzzled. Eventually, a herpetology authority, David Mifsud of the Michigan Herp Atlas, helped me out. I hadn’t recognized the mating calls of the American Toad (Anaxyrus americanus)!

American toads were chorusing their mating song in Cranberry Lake.

I come across single toads in the park periodically, as I did with the Toad above last year at Bear Creek Nature Park. But I’d never before been in the audience as they sing for the females! The water out at the edge of the lake was rippling with their activity. Straining for a sighting, all I could see was a periodic flash of what appeared to be white skin thrust out of the water. I still don’t know if I was seeing toads mating or a fish catching a mouthful of courting toad!

The song was mesmerizing as one toad started the swelling sound, followed by others, until the trills died down. And then after a brief pause,  another round began. It reminded me of the buzz of cicadas on a summer day. Listen!

In the shade at the edge of the lake,  some Ostrich Ferns (Matteuccia struthiopteris) emerged from the moist earth and were unfolding from their parchment-like covers.  Ferns seem almost other-worldly to me, since,  like mosses, they are ancient. Fossil forms of early ferns appeared on earth almost 400 million years ago, long before dinosaurs roamed the earth about 200 million years later! Look at the brown cauls that cover the Ostrich Fern before it opens and then its unfurling green stem with a deep U-shaped groove, a hallmark of this native fern.

Ostrich Ferns unwrap from their brown coverings as they emerge.

You can see why they are also called “Fiddlehead Ferns,” can’t you? And here were a few a bit farther along in their growth. When the sun shines on their unfurling fronds, they just glow!

One Last Encouraging Song to Carry Home

A wet, somewhat battered Northern Cardinal singing with abandon

Since I knew the alternate trails would be too wet to traverse, I re-traced my steps back up the trail, down the Hickory Lane and out to the road. When I entered the parking lot, I was greeted by the cheerful whistle and “cheerups” of a Northern Cardinal (Cardinalis cardinalis) who’d seen better days. After some rainy, cold nights and perhaps an itchy case of mites, he seemed to be having the avian equivalent of a tough day. Despite that, his song was as upbeat and vigorous as ever. I listen entranced and never thought to record him, but luckily I had recorded another male singing the Cardinal’s ebullient spring song back in April.

I stood quietly and just listened to him for a few minutes before I left. And in these difficult days when grief, fear, and anger move in waves across our world, a battered bird still sang. It felt like a model I should try to follow. No matter what life throws at you, that scarlet messenger seemed to say, sing on! I mean to try. I hope you do, too.

Paint Creek Trail: Last Hurrah of Spring Wildflowers, Tiny Pollinators and Nesting Migrators

Since this week’s blog features a variety of wildflowers along parts of the Paint Creek Trail, I thought we’d start with a little visit to the creek itself, which is currently overflowing its banks. The Swamp Buttercup certainly seems pleased with all that moisture! (If you increase your volume, you can listen to the soothing sound of flowing water and birdsong!)

Well, with summer heat settling in, native spring flowers are producing a glorious finale to the season before making room for summer blooms. Spring wildflowers love the weaker spring sun sifting through bare branches. But hot sun and the increasing number of leaves mark the end of spring blooms. Soon these wildflowers will set their fruits, send it to the ground by means of wind, water or simple gravity, and their seed-based reproductive efforts will come to an end for the season.

So before they’re all gone, here are the ones I saw last week on the Paint Creek Trail between Gallagher Road and Dutton Road. You may still be able to spy some of these native beauties as you walk or bike on a sunny afternoon for the next few days.

Discoveries on the Trail between Gallagher and Silver Bell Roads

Golden Alexanders make a sunny yellow blanket beneath the trees just south of the Wet Prairie between Gallagher and Silverbell.

Golden Alexanders (Zizia aurea – above) should still be glowing beneath the light shade of trees near the Wet Prairie after Memorial Day. These members of the carrot family are visited by many spring pollinators, but they can also also self-pollinate. You can see them near the parking lot on Gallagher Road and at other spots along the trail as well.

In the Wet Prairie, a more unusual little wildflower is happily sprouting where the sun is full and the ground is moist. Blue-eyed Grass (Sisyrinchium angustifolium) is really a wildflower, though its leaves look like grass. Best to look for these dainty flowers on a sunny day, since the flowers stay closed on cloudy days.

Blue-eyed Grass on the Wet Prairie is best seen on sunny days.

Another unusual little wildflower huddles under its much taller grass-like stem on the Wet Prairie. Star Grass (Hypoxis hirsuta) shines up out of prairie on a 6 inch stalk topped by a small (3/4 inch) blossom. The six stamens with their angular anthers add to its star-like appearance. Maybe the dew on the leaf in the photo will help you sense the size of this tiny jewel of a wildflower.

Star Grass in the Wet Meadow with dew on a nearby grass leaf

Near the creek, just north of the Wet Prairie, a burst of orange caught my eye and I discovered a native flower that was new to me, Golden Ragwort (Packera aurea).  This plant too has multiple methods of reproduction.  Each of the tiny florets that make up the protruding center of the flower will produce an achene, a winged fruit enveloping a single seed that will disperse into the wind. But ragwort also produces underground stems (rhizomes) aid its spread!

Golden Ragwort brightens the bank edge of Paint Creek near the Wet Prairie

A native, fire-adapted plant which was new to me has the unusual name Bastard Toadflax (Comandra umbellata) and this is not a flax or a toadflax plant.  A report on desertusa.com, claims it was named “toadflax” by the 16th century botanist, John Gerard, because the flowers “be yellow, having a mouth unto a frog’s mouth” and “bastard” because at the time meant “false,” indicating perhaps that it was not a real toadflax. This interesting prairie plant is “hemiparasitic” because it feeds through its roots, but also taps into roots of other plants to get nutrition and water using special structures called haustoria. Bastard toadflax reproduces by rhizomes and produces a small oily fruits enjoyed by birds and mice, who by eating them carry the seeds farther afield.

Bastard Toadflax puts out underground suckers that tap into the roots of other plants.

If you notice a splash of white far back in the Wet Prairie, it might be a patch of  Robin’s Plantain (Erigeron pulchellus), a tough, little native that thrives after prescribed burns. It’s a relative of Daisy Fleabane (Erigeron annuus), a common wildflower in our parks. Unlike Daisy Fleabane, though, Robin’s Plantain more commonly produces one bloom to a stem. Like the Golden Ragwort, it reproduces by both achenes and rhizomes.

Robin’s Plantain, a relative of the more common Daisy Fleabane. Both thrive after prescribed burns.

Early last week, the fluffy, white blossoms of native Choke Cherry (Prunus virginiana) hung  in long clusters along single stems called racemes. After warmer sun later in the week, they had begun to turn yellow. They don’t produce edible cherries, but their bitter fruit appeals to game birds, songbirds and woodpeckers, according to one of my favorite wildflower sites, www.illinoiswildflowers.info.

Choke Cherry trees/shrubs don’t produce edible cherries, but rather a bitter fruit that appeals to birds, but not humans. But their blossoms are beautiful!

All long the trail you’ll see Wild Strawberry (Fragaria virginiana) blooming. Now here’s one bloom you might love to see fading, because its ripening fruit is tiny, but delicious. Good luck getting them before the birds and beasts do, though!

When Wild Strawberry blooms fade, on comes the fruit. But you’ll be lucky to get it before the creatures do.

Discoveries on the Trail from Silver Bell Road to Dutton Road

Despite our late spring, many different native wildflowers were blooming along this section of the trail.  At the bottom of the stairs leading to the creek, just past the parking area, Swamp Marigolds (Ranunculus hispidus) shine bright despite the deep shade. As you saw in the video at the top of the blog, the wetlands along the stream are doing what they do best – soaking up the runoff after heavy rains. And Marsh Marigold is doing its part!

 Farther down the trail, the lavender spikes of Wild Lupine (Lupinus perennis) are blooming. This beloved native produces seedpods open explosively, launching seeds up to seven feet from the plant. Lupine also produces colorful clones as it spreads with rhizomes. Lupines are rising toward the sun in several parks as part of the restoration work being done on our prairies. It’s so heartening to see these lavender blossoms opening up from bottom to top on their stately racemes. And I love the whimsy of its wheel-shaped leaves.

Both the leaves and blossoms of Wild Lupine make it a treasured native wildflower.

Along the berms on the western side of the trail, a perky yellow flower blossoms in bunches. The fuzzy stems and leaves give it the first part of its name, Hoary Puccoon (Lithospermum canescens). According to Wikipedia, the second word “puccoon” comes from an ancient Native American word “poughkone,” and refers to plants formerly used for dyes by Native Americans. I wonder if its roots can turn things that vivid yellow/orange?

The roots of Hoary Puccoon were used by Native Americans for dye. But please don’t pick them to try this at home!

Near the first bridge going south, I found a whole group of native wildflowers that were just finishing their blooms. A small group of Common Trillium (Trillium grandiflorum) still stood in the shade just off the trail. These flamboyant white flowers start turning pink as they age, eventually leaving only their leaves behind to gather up more sun for next years flowers. While true pink- and red-flowering trillium species exist, our Common Trillium just turn pink as they age gracefully.

Nearby Starry False Solomon’s Seal  (Maianthemum stellatum) bore only a rather disheveled version of its star-shaped blossom. After the blossoms, the plant will produce green fruits with purple/black stripes that eventually turn red. Woodland birds and mice enjoy the fruits, thereby carrying the seeds within the berries to new locations.

Starry False Solomon’s Seal has graceful leaves as well as tiny star-shaped flowers.

Native Bees and Tiny Butterflies Busy Pollinating

This may be a Mining Bee, a native pollinator, which specializes in Wild Geraniums.

Many spring wildflowers depend heavily on flies and native bees (of which there are 450 Michigan species!) for their pollination, because many other butterflies and the honey bees finish migrating or emerge from hives only in warmer months. Above is what I think is a native Mining Bee (Andrenidae family) foraging for pollen and thereby pollinating one Wild Geranium (Geranium maculatum) after another! I’m not knowledgeable about bees, but I learned from Pollinators of Native Plants that a particular Mining Bee, Adrena distans, is a specialist pollinator of Wild Geranium, so that’s my guess. Please feel free to correct me if you know more about bees than I do!

A few tiny butterflies were doing their part in pollinating flowers as well. If you see a fluttering wink of blue among the grass stems, it’s probably a Spring Azure butterfly (Celastrina Ladon). These 1 inch pollinators are blue when flying but once they settle, they quickly fold their wings so only the dull gray side shows. It makes them hard for hungry birds – and interested photographers! – to spot. Azures tend to pollinate Golden Alexanders, False Solomon Seal as well as other wildflowers. (Photo on the left by iNaturalist. org photographer Dan Mullen.)

The tiny Pearl Crescent (Phyciodes tharos) quickly fluttered by me and landed on dry grass stems in the Wet Prairie. These little butterflies produce several broods of caterpillars throughout the summer. So watch for tiny (up to 1.25 in.) flashes of orange and black rising from the grass and scurrying across trails all summer long, busily sipping nectar and inadvertently transporting pollen for the flowers.

The tiny Pearl Crescent can be seen now at the Wet Prairie and all summer long in our parks.

The last little butterfly was in a perfect spot to find a mate.  According to http://www.butterfliesandmoths.org, “To seek females, males perch in openings, flats or depressions near woods.” And that’s right where this one was – in the open, on a dead plant stalk near the trees just south of the Wet Prairie. He’s not glamorous but he has a glamorous name, the Dreamy Duskywing (Erynnis icelus). (Duskywings can be hard to tell apart, so again, feel free to correct me!) [Edit:  A man who collects butterflies and has seen many Duskywings told me on Facebook that he believes this is a Sleepy Duskywing (Erynnis brizo)  which he says are more common in this area.} He’s picked a great spot since one of his favorite nectars is the nearby wild lupine. These duskywings like to lay eggs on aspens and cottonwoods, which surround the Wet Prairie.

Possibly a Sleepy Duskywing  waiting on an open perch to be found by a mate.

Migrators Building Nests and, What Else? – Singing!

Late spring is a busy time for birds.  Some have just arrived and are busy singing to attract mates. A Warbling Vireo (Vireo gilvus) sang over my head in one of the Quaking Aspens (Populus tremuloides) near the Wet Prairie. This vireo is rarely seen once the leaves come on the trees; they like to stay high in the treetops and search diligently for caterpillars. But hearing a quick, rolling song high above me, I spotted his vireo shape, gray/olive back and yellow-ish white belly from below. Then he disappeared into the tree canopy. So here’s a photo of one I saw at Cranberry Lake a week ago. Click here to listen to his rollicking warble!

A Warbling Vireo sang above my head near the Wet Prairie. An illusive bird high in the trees with a great song!

The Warbling Vireo near the trail seemed quite frantic, singing insistently and hopping higher and higher in the tree as he did so. At first I thought another male vireo was singing across the trail from him – and I believe that he thought so too! But when I followed the other song, it was one of the great bird mimics, the Gray Catbird (Dumetella carolinensis), doing an imitation of the Vireo’s song and, I think,  driving him crazy! The Catbird was, as usual, adding a few flourishes of his own, but it seemed as though the Vireo found his call an annoying form of competition! For a sample of the Catbird’s wonderfully complex, mimicking song, click on the word “Song” at this link.

The Catbird’s mimicry of the Warbling Vireo’s song seemed to fool the vireo into thinking he had competition!

A pair of Baltimore Orioles (Icterus galbulaswooped down onto the Wet Prairie one afternoon. The female immediately disappeared into tall grass. It’s likely that she was carefully choosing grass stems out of which she could strip fibers for weaving her long, sack of a nest. Evidently, the male’s job was to stand guard while she had her head down.

A male Baltimore Oriole stands guard while his mate searches for just the right plant fibers to weave her bag-like nest.

Suddenly, the female oriole lifted out of the grass, followed immediately by the male, and they swooped into a tall Cottonwood (Populus deltoides) on the northern side of the prairie. She disappeared into a clump of leaves hanging high over the meadow, but I could see the branches moving as she worked and a tiny bit of the growing nest  (look in the center of the photo below through the leaves). I found a great little YouTube video of the Oriole’s weaving process, which is really incredible. Imagine tying knots and twirling fibers around a branch using only your beak!

The beginnings of an oriole nest high over the Wet Meadow

I heard a pair of  Eastern Kingbirds (Tyrannus tyrannus) fluttering together from tree to tree and stopped to watch. After giving what sounded like greeting calls, they soared up into a tall tree near the Wet Meadow. The female stood at the edge of a very messy nest which she was constructing on top of what appeared to be an old squirrel nest. The male doesn’t help build the nest, so while she worked, he stood guard in a nearby tree. I read in the Stokes Guide to Bird Behavior (Vol. 1) that Kingbirds build preliminary nests before settling into a final one to lay eggs. I’m guessing this may be just a trial nest, since building on a squirrel nest seems like an iffy location! (Squirrels are known to eat bird eggs!) The fine fibers drooping down over the top of the squirrel’s dry, gray branches and leaves are the female kingbird’s doing.

A female Eastern Kingbird seems to be constructing a preliminary nest on top of an old squirrel nest.

Kingbirds are identifiable from a distance by their upright posture – what one member of the birding group calls their “military stance.” And note the white tips on the tail feathers.

Every Nature Walk has its Special Moments

Last week, I had to smile at this seemingly relaxed male Northern Cardinal (Cardinalis cardinalis). He hopped slowly up and down a slope by the trail, picking up and rejecting items he found between the grass stems. With the grass taller than his head and his red crest (which is usually erect) drooping backwards, he reminded me of an avian Red Riding Hood!

It’s little things like that – and seeing the Blue-eyed Grass staring up at me – or watching the two Eastern Kingbirds near their nest – that send me home happy from every foray into the natural world. And these grant adventures only require the right clothes for the weather, water-proof shoes, a little application of bug spray at times and my undivided attention for an hour or so. I usually take my camera along,  but walks without anything but my trusty binoculars are just as rewarding. If you ever feel a bit weary as the poet Wordsworth once did, “The world is too much with us, late and soon/Getting and spending, we lay waste our powers…,” try a foray into our parks with your curiosity set at high alert. I’m confident that nature will send you home refreshed and with moments to share with others. Thanks for sharing mine!

Cranberry Lake: Summer Ushers in Birds, Butterflies and Blossoms

Wild Geraniums along the Hickory Lane

 

Blog and Photos by Cam Mannino

Summer finally made its appearance all over the woods, meadows, wetlands, and forest edges of Cranberry Lake Park.  After a prescribed burn this spring, geraniums and trillium emerged under the huge Shagbark Hickories that line the park’s western edge. Summer birds, including the tiny warblers and other new arrivals, are singing lustily to establish their territories and attract interested females as they begin to build nests. Butterflies are just starting to dance above the greenery in the dry meadows. And the hibernators – like snappers, raccoons and  leopard frogs – get back in action after their winter snooze. The transformation from spring to summer has well and truly begun.

Birds and Blooms in the Large Sunny Meadows

Small Yellow Warblers (Setophaga petechia) welcome visitors from the high treetops just north of the parking lot. The male with his chestnut-striped breast sings his “sweet-sweet, I’m a little sweet” song as he darts here and there, frequently out of sight in the greenery. Luckily a female with much fainter stripes ignored me while probing for insects in some smaller trees.

A female Yellow Warbler probed the branches of a small tree near the western entrance to the park.

At the edge of the big northern meadow one afternoon, I heard the two buzz call that Ben identified on an earlier birdwalk. As I scanned the bushes with my binoculars, a lovely Blue-Winged Warbler (Vermivora cyanoptera) filled my view. By the time I raised the camera, it was gone. Joan Bonin, a gifted local photographer and birder, kindly offered her stunning photo taken a week later at Port Huron State Recreation Area.  Thank you, Joan!

Red-eyed Vireo (Vireo olivaceus) made a brief appearance in a small meadow opening at the edge of a forested wetland. Evidently these little birds sing incessantly, especially on warm summer afternoons. In fact, Cornell reports that one determined male “sang 22,197 songs in the 14 hours from just before dawn to evening, singing for 10 of those hours.” I missed both his song and a photo, but another gifted local photographer and birder, Bob Bonin (Joan’s husband), kindly shared his lovely photo taken at the Tawas migration site last year. Thanks to Bob, also!

Steve, a fine birder that I met at Bear Creek Park, commented on the last blog that he’d seen an Indigo Bunting (Passerina cyanea) at Cranberry Lake in the last two weeks.   Cornell ornithologists report that all blue birds actually have no blue pigment in their feathers. “Their jewel-like color comes instead from microscopic structures in the feathers that refract and reflect blue light, much like the airborne particles that cause the sky to look blue.” Since Steve saw the bird and I didn’t, here’s that  bright little piece of sky in another beautiful shot by Bob Bonin.

Indigo Buntings sing as many as 200 of their two or three phrase songs per hour at dawn according to Cornell Lab.

Butterflies dance across nearly every sunny or dappled area of Cranberry Lake. In a shady corner near the northern meadow, an Eastern Tiger Swallowtail (Papilio glaucus) paused for just a moment before sailing high into the treetops and away. The band of blue spots at the bottom of the hindwing (plus the orange center spots) marks this one as a female.

A smaller, but equally striking butterfly, the American Copper, sampled the blossoms of Common Blackberry bushes (Rubus allagheniensis) that have multiplied mightily since the recent burn.

According to Wikipedia, the male Coppers set up “small territories which they will defend vigorously against rival males or indeed any unlucky passing insect. Even the shadow of a large bird passing overhead is enough to elicit a response.”

It’s clear where this medium-sized [edit:  My memory failed me.  It’s actually very small!] butterfly  got its name, eh?

An American Copper butterfly rests on a grass stem between the multiplying Blackberry bushes.

This female Eastern Tailed-Blue butterfly (Cupido comyntas) doesn’t wear the beautiful blue that her mate flashes when he flies. But you can still see a bit of blue in her modest gray. These medium-sized butterflies almost disappear when they land and fold their wings, which are light gray underneath.

A female Eastern Tailed-blue butterfly is a more muted gray-blue than her brighter blue mate.

Along the Hickory Lane, More Bird Song and Early Summer Blossoms

On an early bird walk, a Brown Thrasher (Toxostoma rufum) belted out its complex mimicry song from the top of a tree on the Hickory Lane. If you enjoy the Gray Catbird’s mix of other birds’ calls and the odd noise,  you’ll love (as I do) the crazy mix of continuous loud song from the thrasher. That morning he was too high up for a good photo. Fortunately  a few days later, a tired thrasher, preparing for sleep on a cool spring evening at Gallagher Park, struck a pose for me.

This Brown Thrasher was preparing to sleep on a cool evening – one leg tucked up under his feathers which were fluffed for warmth

Along the lane,  a tiny mimic (listen to the second recording at this link), the Blue-Gray Gnatcatcher (Polioptila caerulea), busily fluttered and hopped about a tree trunk foraging for insects. How I’d love to see their nest!  Cornell Lab says they “use spiderweb and lichens to build small, neat nests, which sit on top of branches and look like tree knots.”

The Blue-gray Gnatcatcher cocks his tail with its white outer feathers this way and that as he searches for insects – but not many gnats, despite its name!

On a later visit, a male House Wren (Troglodytes aedon), bubbled with spring song. Despite their diminutive size, wrens can be fierce in asserting ownership over a preferred nesting hole, even dragging out eggs of other birds or pecking larger adult birds. Wrens need to maintain a narrow range of temperature for their eggs to hatch which might explain their fierceness over nesting sites. Perhaps this male’s insistent song was just a first salvo in the competition.

The effervescent singing of a House Wren on the Hickory Lane.

In the area between the Hickory Lane and the large marsh to the east, a strange upward sliding call made my husband and I stop and listen one afternoon. We never saw the singing male, but we did spot the female Swainson’s Thrush (Catharus ustulatus), that I originally thought was a robin from its stance.  Sorry for the slight blur of a quick photo.

A female Swainson’s thrush stopped with us to listen to the hidden male singing his ascending whistle of a song.

Below these avian songsters, early summer blossoms came burgeoning forth after a recent prescribed burn. The lane was filled on both sides with the Wild Geraniums (Geranium maculatum) you see at the top of this blog. A small white plume poked through leaves of what Ben tells me is either red or white Baneberry (g. Actaea). The actual baneberries that form later are highly toxic, so please don’t eat them! (They’re very bitter so you wouldn’t like them, but children might be tempted because they’re very colorful and shiny.)

Two varieties of the same flower also bloomed on the lane.  Solomon’s Seal (Polygonatum biforum) produces its blossoms beneath the stem and its leaves are smooth below, unlike a nearly identical plant, Downy Solomon’s Seal (Polygonatum pubescens) that has fuzz on the underside of the leaves.

Solomon’s Seal hangs its blossoms below the stem, as does Downy Solomon’s Seal but the undersides of leaves on Solomon’s Seal are not covered in downy fuzz.

False Solomon’s Seal (Maianthemum racemosum), on the other hand, produces its flowers on a stem that stands above the leaves. Odd name. Perhaps the name was given by someone fooled into thinking at first that it was Solomon’s Seal? Who knows….

False Solomon’s Seal carries its blossoms on a stem above the leaves.

Early Summer in the Shadowy Wetlands near Cranberry Lake

Cranberry Lake has a wonderful collection of vernal pools and woodland ponds as well as the lake itself. I’ve come to love these areas because they are always rich with wildlife, especially birds!

I heard the easily-identified “witchedy, witchedy” call of one of my favorite small migrators, the black-masked Common Yellowthroat (Geothlypis trichas). He was in a favorite location, in low bushes near a wetland. I never got to see the ones that I heard repeatedly at Cranberry Lake, but I saw this one the following week at Charles Ilsley Park.

The Common Yellowthroat sings his “witchedy-witchedy” song from low bushes, usually located near a wetland.

In a forested pool, a Common Snapping Turtle (Chelydra serpentina) had draped its head over the edge of a log, evidently eating plants below. At first, I thought it had been beheaded somehow! But on hearing me crunching in the twigs, it lifted its pointed snout into the air, quickly slid backwards into the water and disappeared. So all I got was this odd, headless shot.

A snapper in a forest pond with its head submerged eating plant material, no doubt.

A few minutes later, a male Common Grackle’s (Quiscalus quiscula) iridescent head shone in a ray of sunlight on the same log. Clearly frustrated at finding nothing to eat beneath it, he tossed that irritating, useless chunk of bark into the water.

A male Common Grackle tossed his chunk of bark into the water after checking and finding no edible insects underneath. At least that’s how it appeared.

One of summer’s pleasures is being escorted along a trail by dragonflies and damselflies – and then I managed to shoot one swooping over the water when I reached at Cranberry Lake.  Perhaps a mating flight?

In April, lovely little blossoms with pink scallops and ruffled edges emerged on the native Highbush Blueberry (Vaccinium corymbosum) near Cranberry Lake. A few weeks later, the fruit was beginning to form. I hope birds, animals and we humans leave some berries uneaten so it keeps spreading!

When I reached Cranberry Lake, I found two Sandhill Cranes (Antigone canadensis) standing on a sandbar near the shore. One of them “gave me the eye” between the old stems of purple loosestrife.

On the way back up the trail from the lake one morning, Ben spotted a weary raccoon who appeared to have made a hasty bed in the fork of a tree after a night of foraging. It opened one eye as we birders peered from below.

A weary raccoon opens one eye to look back at us from what appears to be a hastily constructed napping place.

On the edge of the path heading toward one of the large meadows, I heard the snoring rattle of the Leopard Frog’s song coming from a nearby wetland. And then, oops! – one appeared right in the path between two wet areas. Nice to have frog song along with bird song on a summer walk!

The Leopard Frog’s appearance nicely matches its name. Its song is a low, snoring sort of rattle – very distinctive.

Nature by Ear as Well as by Eye

The forest pond where the Grackle and the Snapping Turtle spent a quiet afternoon.

To truly savor the pleasures of nature in early summer requires tuning my ears as well as opening my eyes. Though I’m just learning bird songs and frog songs, every time I identify a voice in nature’s chorus, I feel more connected, more embedded in the natural world. Listening, as well as careful, patient watching, begins to turn a green landscape into an intricately woven tapestry of life in which we humans are just one colorful thread.

Photo(s) of the Week: Some Native Spring Wildflowers Relish “Disturbance”

Golden Alexanders flourishing beneath the trees south of the Wet Prairie on the Paint Creek Trail

Curiously, many native wildflowers like a little disturbance now and then. So township natural areas manager, Dr. Ben VanderWeide, sees that they get just what they need! By eliminating invasive shrubs, native plants grow stronger as sunlight reaches their previously shade-suppressed leaves. Regular prescribed burns help many fire-adapted native species emerge from the seed bank and thrive. The Golden Alexanders (Zizia aurea) along the Paint Creek Trail (seen above) are loving all the upheaval from invasive shrub removal three years ago. Yellow Lady Slippers (Cypripedium parviflorum), and Swamp Buttercups (Ranunculus hispidus) are flourishing for the same reason at Gallagher Creek Park. Native wildflowers are emerging in greater numbers all over Cranberry Lake Park after a recent burn. Below is a small sampling of local native wildflowers which benefit from the Parks Commission’s efforts to restore our natural heritage.

Bear Creek Nature Park: Little Spring Dramas Everywhere You Look

Native choke berry shrubs (Prunus virginiana) burst with blooms to attract  pollinators before the trees leaf out.
Blog and photos by Cam Mannino

Late April and early May are full of dramas. Birds hassle each other over territories. Some turn their brightest feathers into the sunlight or sing elaborately constructed songs  to impress the ladies. Snapping turtles roil the waters of the marsh as they twist and turn with their partners, butting heads and biting as they perform their mating dance. Late spring wildflowers and smaller trees hurry to show their best blooms to attract pollinators before bigger trees cloak them in shade. It’s a bustling, slightly crazy season – and isn’t it great?

 

Migrating Summer Birds Busy Courting, Hassling and Scouting for Nests

Down at the Center Pond one cool spring morning, the birding group watched a Green Heron (Butorides virescens) warming itself on a log at one end of the pond.  Its neck wasn’t stretched over the water, so it wasn’t seriously fishing; it just sat there peaceably. Gradually,  a pair of passive-aggressive Canada Geese (Branta canadensis) noticed its presence and decided, evidently, that they wanted the pond to themselves. They cruised slowly up to the heron until one of them was nearly beak to beak with it. The heron just sat. They joined forces and approached together. The heron just sat. Finally, one goose climbed onto the heron’s log, while the other positioned itself directly in front of the hapless heron. It sat for another minute and then finally acquiesced, fluttering off to the muddy shore nearby. Conflict successfully avoided, it probably found plenty of snails, insects and amphibians to eat while waiting for the geese to depart.

Sometimes the ongoing drama is a little less obvious.  Rose-breasted Grosbeaks (Pheucticus ludovicianus) are plentiful in Bear Creek this year. One morning a male turned his bright pink breast patch to the sun and trilled his elaborate spring song repeatedly for his more modestly dressed mate. (If you hear a fancy version of the robin’s song, there’s likely to be a male grosbeak nearby.)

A female Rose-breasted Grosbeak listens to the male’s operatic song.

But nearby, there’s a careful observer. The female Brown-headed Cowbird (Molothrus ater) is high in a tree listening, too.

A female Cowbird high in a tree watching to see if a likely bird builds a nest in which she can lay her eggs. The Grosbeak’s perhaps?

She’s watching for a likely nest in which to lay her eggs. Maybe she’s hoping  the grosbeaks will be the ones to nurture and raise her young. Fortunately, the grosbeaks aren’t great prospects. They’re big enough to push the eggs out of the nest – if they notice them. Some birds do and some don’t. The drama hasn’t reached Act II.

In the small meadow west of the pond, a male Gray Catbird (Dumetella carolinensis) spent the morning stringing together short phrases – whistles, tweets, trills and  imitations of birds, frogs, even occasionally machinery!  His complicated song can go on for minutes without repetition! This male combined song with ruffling his feathers and chasing after the female who was playing hard-to-get. She’d stop to listen, fly off and then dart toward him. He’d pursue her, fluff his feathers again and sing something new. And on they went at the forest edge and among the meadow’s small trees and shrubs.

The male catbird taking a quick pause before ruffling his feathers and breaking into elaborate song.

Some migrators arrive in busy flocks, just stopping over for a short while to refuel before flying north. This week, a flock of 6 or 7 White-Crowned Sparrows (Zonotrichia leucophrys) rode in on a south wind during the night and spent the morning gobbling whatever they could find at the edge of the trails. Such a handsome little sparrow with its striped crown!

A small flock of White-Crowned Sparrows stopped to forage at Bear Creek on their way to cooler nesting grounds farther north.

Some birds fly in for just a short time to breed and then return to southern climes. This Orchard Oriole (Icterus spurius), the smallest of the orioles, flitted quickly among the branches, nibbling on sweet leaf buds for a little quick energy. Even if he finds his yellow-green mate and nests, he’ll likely be gone by mid-July – back to his favorite haunts in Central America.

The smaller, russet-colored Orchard Oriole may nest here, but will leave by mid-July for Central America where he spends the rest of the year.

High overhead, a pair of Sandhill Cranes croaked their wild cry, sounding and looking like two prehistoric pterodactyls with their giant wings. (Click on photos to enlarge; hover cursor for captions.)

The warblers, the tiniest of migrants, have begun to arrive.  A week ago a fellow birder helped me spot two species – the Yellow-rumped Warbler (Setophaga coronata) and the Yellow Warbler (Setophaga petechia) – and, we think, a Ruby-crowned Kinglet (Regulus calendula.) I didn’t manage to take any decent photos since some ate high in the tree tops and others hopped madly from limb to limb nibbling on leaf buds. So here are three photos from last year just to jog your memory.

In the western meadow, an Eastern Kingbird (Tyrannus tyrannus) paused on a stalk. Kingbirds have a crown of red, orange or yellow feathers under that black cap, but they only show when they’re attacking a predator. I’ve never seen them. According to Cornell lab, this solitary, feisty bird changes his lifestyle in the winter, traveling in flocks all along the Amazon and eating fruit instead of Michigan insects. A favorite photo below from a few years ago shows his crown just slightly raised and his red gaping mouth.  Maybe he’s feeling just a wee bit aggressive?

The Eastern Kingbird has colored feathers under that black cap that show when he’s aggressive toward a predator.

Drama in the Wetlands as Well

Over in the marsh, a very small Snapping Turtle (Chelydra serpentina) and a MUCH larger one roiled the water at the far end of the marsh. The difference in their neck lengths will help you determine their relative size in the photos.

I assume the smaller one was the male as he attempted to mount the back of the female’s huge shell at one point.   Snappers generally do a lot of face biting when they mate, sometimes injuring each other. The photo below may look like a kiss but it’s more likely that the small turtle on the left is approaching to bite some indeterminable body part of the larger on the right. It didn’t look as though things worked out too well for either of them. After some rolling and tumbling in the marsh, the smaller swam off and the larger floated calmly in the distance.

What looks like a turtle kiss may actually be a bite that the smaller turtle (left) is giving the larger as part of the attempted mating process.

Blue-spotted Salamanders ((Ambystoma laterale) reproduce in a less excited manner. According to the Michigan Department of Natural Resources, salamanders emerge from their burrows on the night of the first snow-melting rain (now that would be dramatic to witness!) and go to the nearest vernal pool After a little nudging and hugging, the male deposits a sperm-topped cone of jelly on the ground in front of the female. She takes it in to fertilize her eggs, which are laid in the water in the next day or so. By mid-summer, the hatched tadpole-like larvae develop lungs instead of gills and absorb their tail fins, taking adult form.  Red-backed Salamanders (Plethodon cinereus) lay their eggs in burrows and their young hatch as miniature adults. Here are some salamander eggs and a salamander larvae/tadpole that the monitoring team found in a pool last year, plus three different species of juvenile salamanders under some wood in the park two weeks or so ago.

In the Woods, Not Much Drama, but Burgeoning Life

Again this year, a raccoon is inhabiting the giant hole in the Oak-Hickory forest. Other years this has meant a passel of playful kits by the end of May. I saw nothing until I stepped into the crunchy leaves at the trail’s edge and this curious face popped up at the edge of hole.

A raccoon has found the hole that is often used by females to bear and raise their young. We’ll know by the end of May.

The Red Admiral Butterfly (Vanessa atalanta), a migrating insect who probably overwintered in southern Texas, arrived at the wood’s edge a couple of weeks ago. According to Wikipedia, Red Admirals usually have two broods here between May and October.

The Red Admiral overwinters in Texas but comes here to have 2 broods between May and October.

Under the growing canopy of bright new leaves, a carpet of Wild Geranium (Geranium maculatum) is blooming. In the blossom below, a tiny bee from the Halictadae family has curled up to feed on flower nectar. These tiny bees are commonly known as “sweat bees” because they like to lick salt from us humans (luckily, their sting is very minor). This bee’s bright metallic green may mean it’s an Augochlora Sweat Bee (Augochlora pura), solitary bees who don’t live socially in hives. If you know your Michigan bees, please feel free to correct me.

 The Little Dramas Keep Life Coming

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

The dramas of spring creatures mean life continues. The best singer, the most beautiful feathers, the best provider of a good territory get chosen and a new generation begins. Fortunately, the temporary territorial disputes of birds don’t usually result in death or destruction. One bird moves on to new territory and in many cases, joins his former competitor in a fall flock which ends up feeding calmly together on winter feeding grounds. Nature knows that both low level conflict and general cooperation keep life going, even improving, generation by generation.  Maybe we humans should take a lesson from them?
