Photos of the Week: Hungry Fledglings and Prairies Bursting with Color

Mid-summer on the Eastern Prairie at Charles Ilsley Park

The north and east prairies at Charles Ilsley Park get more glorious each summer as restoration brings the return of colorful wildflowers blooming again in their native soil. Great sweeps of Black-eyed Susans (Rudbeckia hirta) stare  up into the blue sky surrounded by the tousled, lavender blossoms of Bee-balm (Monarda fistulosa) and flat, compact cushions of white Yarrow (Achillea millefolium).

 Tall Yellow Coneflowers (Ratibida pinnata) sway in even the slightest breeze.

Yellow Coneflowers tower over the carpet of color on the Eastern Prairie at Ilsley.

The peaceful  beauty of these undulating prairies on a summer afternoon is mesmerizing. The nodding dance of flowers and the flutter of butterflies among them soothe the spirit much like the sight and sound of a peaceful ocean –  but with such a variety of color and movement! Wonderful!

Last Sunday along the entrance trail, young Barn Swallows (Hirundo rustica) perched high on a dead branch, waiting to be fed. They begged in the usual fledgling fashion, fluttering their small wings rapidly and calling. Finally, a parent arrived (lower left in the photo below), settled and seemed to be considering which to feed first.

Then the adult swooped out across the meadow, gathering insects in its open beak. It returned and managed a short mid-air pause, beating its wings vigorously as it speedily popped food into one of the open beaks.

Then off went mom or dad again to scoop up more bugs! Such a challenging job to feed all four of those hungry youngsters! (One is behind the lowest branch.)

In the center of the park, where restoration planting happened just weeks ago, the melt ponds are drying up, leaving a strange, foamy surface. Water is so crucial for wildlife that it’s always a reliable spot to find something interesting.

A slim bird that I believe was a young Killdeer (Charadrius vociferus), with its naturally worried look, poked along the edge of the pond.  The Stokes’ Guide to Bird Behavior (Vol 2) describes juvenile Killdeer as “very similar to adults except that their upper feathers are margined with lighter edges, their dark neck bands are narrower and often gray or brown instead of black.” I think this one fits that description. Do you agree? Once the young are ready to be on their own, their parents breed again. But the male keeps an eye on the youngsters from the first brood from a distance, while the female incubates the new eggs.

A young Killdeer was not quite as adept at finding food yet. Its parent may feed it as evening comes on.

Two fledgling Eastern Bluebirds (Sialia sialis), with just a touch of blue on their wings,  watched the killdeer from a small, bare tree nearby. No foraging for them right then. Perhaps they were hoping a parent would come to stuff their beaks like the swallows, but at the moment, no such luck. Like the Killdeer adults, their busy parents may also be encouraging their first brood to feed on their own while the adults start a second. (Click on photos to enlarge; hover cursor for captions.)

Some adult birds hung out near the pond as well. A Green Heron (Butorides virescens) was so intent on feeding that it flew toward us to find some open water.

This heron was a skilled fisher! It found a bounty of food in the drying pond. Watch below as it stalks and then catches what appears to be a crayfish nymph. (Use the pause button if you need more time for captions.)

The fiercely territorial Eastern Kingbird (Tyrannus tyrannus) looked remarkably unruffled by the other species exploring the resources of the pond below. And nearby in a tree at the edge of the center field, an adult Song Sparrow (Melospiza melodia) looked as though it must have been preening vigorously since its feather were very ruffled! Drat those feather mites!

Summer turned into an unusually busy time for me this year. So I relish escaping into our parks, where I can watch young birds learn the ropes of feeding, or just quietly enjoy the way Yellow Coneflowers sway above a multi-colored prairie. I recommend it to you as a peaceful alternative to a day at the beach.

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

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

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

Winter 2017: Serenity Rises as the Snow Falls

The Tree Line Between Two Prairies, Charles Ilsley Park

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

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

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

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

Summer 2017: Butterflies Galore as Restored Prairies Began to Bloom

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

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

Autumn 2017:  Birds Departed South, and Fall Wildflowers Bloomed

Autumn color at Cranberry Lake Park

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

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

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

Lost Lake Nature Park: Fishers of all Kinds, a Tree’s Generous Afterlife and a Lively Meadow

Fragrant Water Lilies (Nymphaea odorata) in Lost Lake

Lost Lake Nature Park, a small 58 acre park probably best known for its sledding hills, hums with life in every season. Right now, fishers of all sorts – birds, animals and humans – are testing their skills against the fish in its 8-acre kettle lake. In the meadow that slopes upward along the sledding hill, dragonflies bask on dried flower heads in early fall sun while a crane fly dances over the soil, laying her eggs among tall native grasses and bright wildflowers. And deep in the woods that cover the slopes, an old tree stump sustains a vivid collection of life. On every short trip this month, Lost Lake sent me home with a little something special.

Around the Lake: Fishers, Flowers and Frogs

On each of my visits, Green Herons (Butorides virescens) foraged and flew at Lost Lake. On my first visit, a young Green Heron stood at the corner of the dock, surveying the eastern pond in the late afternoon sun. The telltale field marks are the streaked side of its head and breast, its greenish yellow legs and its smaller size. Two adult Green Herons flew overhead, giving their distinctive alarm flight call (at this Cornell link under “advertising call”) and later I saw them more  closely in a wetland down the road. The adults are a bit more glamorous than their young, I’d say.

A young Green Heron peruses the far side of the pond from the dock.
A mature Green Heron flew to a marsh nearby

On my second visit, the herons were only visible through binoculars on the far side of the lake. But the third time, I was rewarded. A very young green heron, about half the size of an adult, landed in the pond, flew to a mud flat fairly near the dock and began to fish. I watched this skillful youngster successfully snag a meal twice, and then watched as it struggled to swallow its trophies, as you’ll see in the slideshow below. (Use pause button to read longer captions.)

On my last visit, a small green heron again appeared, perhaps the same one, this time flying above the head of a fishing  Great Egret (Ardea alba).

The egret was also a successful fisher, though swallowing took no apparent effort for this elegant bird with a long graceful neck. (Click to enlarge; hover cursor for captions.)

As I was leaving the deck one afternoon, I saw movement out of the corner of my eye. As I turned, an American Mink (Neovison vison) paused at the end of the dock before slipping away into the tall grass. I’d never been that close to a mink before. Quite exciting! Mink always live near water and do lots of fishing, eating crayfish, frogs, and fish as well as rodents and occasionally birds or their eggs. A mink coat, with its dark sheen of guard hairs, looks best on this little creature, I think. Since the mink moved too quickly for a photo, I’ve borrowed one from a gifted and generous photographer at iNaturalist who uses the name DigiBirdTrek.

On two afternoons over Labor Day weekend, human fishers showed up at Lost Lake as well – a threesome one day and a young couple another.  Not sure if they were as successful as the green heron!

Human fishers enjoy Lost Lake as well.

With all those fishers, it’s not surprising that this tiny green frog squeaked and leapt into the pond as I walked off the dock one afternoon. It may have been a young Bull Frog (Lithobates catesbeianus), since it has a fold around the tympanum rather than a ridge running back from the eye, which would indicate a Green Frog (Lithobates clamitans). Small bullfrogs are also more prone to squeaking when alarmed; I’ve never heard a squeak from a small green frog.  I’m open to correction, though, since we can see so little of this small frog.

Admittedly, the pond is not at its best right now in terms of flowers. Many of the water lilies closest to the shore have withered into a brown mass and the brown leaves of some Pickerel Weed (Pontederia cordata) stalks protrude from the water near the shore. But in the distance, the water lilies float on a bed of green (see above) and in some places, the lovely lavender plumes of the pickerel weed still stand tall with their huge, graceful leaves. Along the shore, the sunny ball-shaped heads of Sneezeweed (Helenium autumnale) nod in the breeze near the delicate purple chevrons of Great Blue Lobelia (Lobelia siphilitica).

Down the road, at the same wetland where I saw the mature Green Heron, an elusive family of Wood Ducks (Aix sponsa) caught my eye. On each trip, I’d notice a threesome of young ducks being shepherded by the male parent.  This dad wanted nothing to do with me and quickly herded his family around a bend, or behind greenery at the edge of the water. But one day I was able to catch two fairly good shots of dad and his three offspring.

Into the Woods: A Blackened Stump with Vivid Life and Some Clever Seeds

The path into the woods at Lost Lake in dappled afternoon light

The path into the woods starts at the end of the driveway that runs in front of the caretaker’s home, and you’re welcome to use it.  It’s a short, uphill path that is quite steep at the end and then runs quickly downward as you descend the sledding hill. The forest floor is deep green and beautifully dappled by sunlight.

On the dry, wooded hillsides,  some native grasses and wildflowers are beginning to create and disperse seed. The long graceful pods of Sicklepod (Boechera canadensis), a native member of the mustard family, crack open when dry, releasing a long line of seeds to the wind. Jumpseed (Persicaria virginiana), another native, is appropriately named; according to the Minnesota wildflower site, its seed “jumps off the stem at the slightest touch,” sometimes as much as 10-13 feet. Cluster-leaved Tick-trefoil (Hylodesmum glutinosum) makes cool fruits called loments that have little pods with one seed each that travel by sticking to anything that comes close. And an old fave, Bottlebrush Grass (Elymus hystrix), sends its seeds flying on arrow-shaped “awns” that can actually stick upright in the earth when they land. Plant evolution has produced some very creative ways to spread seed!

At the bottom of the hill, in the deeper shade of a wetland, I discovered an old black stump that hosted a variety of brightly colored life. According to Peter Wohlleben, author of The Hidden Life of Trees, the insect and fungal life of felled stumps and logs help the forest by breaking down the nutrients held in the trees’ wood for hundreds of years. The process of decomposition can take as long as the life of the tree – in the case of oaks, up to 300 years! And eventually those released nutrients feed the tree’s offspring and other trees and plants. Well, this old tree stump, a White Pine (Pinus strobus), was busy doing just that. Its surface presented all kinds of colorful life that was busy working to break down its nutrients or using it for shelter.

A tree stump hosting lots of life in the forest at Lost Lake – harvestmen, ants, moss and mushrooms.

What originally caught my eye was a group of tiny, deep orange/red mushrooms.  I couldn’t determine the species of these mushrooms, though they could be an early stage of the Jack-o’Lantern mushrooms (Omphalotus olearius) featured recently at Bear Creek. A few minutes later a second spot of red caught my eye. A group of Harvesters (order Opiliones, suborder Eupnoi), which are arachnids, but not spiders, scrambled around the inside of the stump. The one below came festooned with tiny bright red mites! And then I spotted a ruby red ant, whose species I was unable to discern.  And a lovely patch of green and orange moss with its sporophytes tipped with the capsules that contain its spores graced the flat top surface like a miniature forest. Quite a colorful bunch of creatures, bryophytes (mosses), and fungi working and living on this old stump!

Down the Hill to the Meadow – Basking Dragonflies, A Dancing Crane Fly, Wildflowers and Native Grasses

A soft lavender bank of Bee Balm (Monard didyma) still blooming near the caretakers’ lawn before you enter the woods

Wildflowers are still blooming in glorious color on the steep sledding hill, the small meadow below it and a short distance from the pond. A few Yellow Coneflowers (Ratibida pinnata) hang on nearby, their drooping petals still golden in early autumn light, along with some Smooth Asters with their dark red or yellow centers (Symphyotrichum laeve). Showy Goldenrod (Solidago speciosa) and Grass-leaved Goldenrod (Euthamia graminifolia), both late summer/autumn wildflowers, are being visited by native bumblebees. Pale/Thin-leaved Sunflowers (Helianthus strumosus), that love the forest edge,  shine bright under the trees as you approach the wood. An Evening Primrose (Oenothera biennis), with its four-parted stigma forming the characteristic x-shape, stands alone at the edge of the parking lot. Near the entrance to the woods, the slender pods of Poke Milkweed (Asclepias exaltata), a milkweed of shady savannas, will eventually dry and break open to release their seeds to the wind. Among the flowers, native grasses sway, like Big Bluestem (Andropogon gerardii) which is now flowering and Indian Grass (Sorghastrum nutans) which has started to form its seeds.

This slideshow requires JavaScript.

Among these grasses, a group of Autumn Dragonflies (Sympetrum vicinum) rested on dried flower heads, needing a bit more sun on cool days. This species has a little cloud of yellow near the base of the hindwing. They hatch out in August and September, providing more late summer color. Mature males are the easiest to spot with their red abdomen. Juvenile males (in closeup below) have a yellow thorax and a yellowish brown abdomen, according to Wikipedia. And the females (second and fourth from the left  in the photo at the far right below) have a brown thorax and a brownish/red abdomen. I find it hard to distinguish between females and juvenile males in Autumn dragonflies,  so feel free to correct me!

One of the oddest sights at Lost Lake occurred on my last visit. I saw something with very long legs dancing vertically, up and down, above small holes in the earth between the grass stems. Eventually, after developing and cropping a lot of photos and doing online research, it became clear that I’d been seeing a Tiger Crane Fly (Tipula dorsalis) laying her eggs in the soil. Taking photos of a crane fly rapidly jumping up and down is a bit challenging, but if you look closely, I hope you can see her curving, vertical body as she pokes the needle-sharp ovipositor at the end of her abdomen into the soil. Her narrow wings and very long legs were splayed in every direction as she danced from one hole to another, laying potentially hundreds of eggs. Click this link  from bugguide.net for a much better photo than mine!

A Tiger Crane fly holds herself vertically as she jumps into and out of a hole in the earth, laying her eggs.

By the way, crane flies are gangly, harmless creatures who can’t bite or sting humans or animals as the unrelated mosquitoes do. Crane flies live only 10-15 days and drink nectar, if they eat all (some don’t!). The only damage they do is in their larval form, when the caterpillars, called “leatherjackets,” do eat some turf grasses and agricultural plants.

The Persistence of Life

Despite the ravages of early September – hurricanes one after another, wildfires, earthquakes – here in the protected natural areas of Oakland Township, life persists. The young green heron successfully fishes its food from among the water lilies. In forest shade, the flowers and grasses produce seed, relying on another spring to foster the next generation. A crane fly dances above the earth, seeing to it that their offspring still float over the grass stalks when summer comes again. And what about us?  Well, of course, we’re members too in that community of life on earth. I like the thought that as you and I foster and nourish that community, we’re doing our part to see that life persists on this little blue planet.

Bear Creek Nature Park: Young Birds, a Tiny Forager in Disguise and So Many Wildflowers!

Boneset and Joe Pye in the Eastern Meadow at Bear Creek

Late summer wildflowers nodded and swayed in the meadows, woods, wetlands and native gardens at Bear Creek this August. Monarch butterflies paused on the blossoms, competing mostly with industrious native bumblebees. And all over the park, young birds were feeding on their own – or in a few cases, still getting fed by doting adults. In the center pond, a tiny creature foraged in disguise!  

Blog post and photos by Cam Mannino

So take a wander along the trails, as goldenrod transforms the park from green to gold, and enjoy the bright beauty of summer’s last hurrah!

 

Like Some Human Youngsters, A Few Avian “Adolescents” Stick Close to Mom or Dad

A young Eastern Kingbird (Tyrannus tyrannus) hid in a shrub in the eastern meadow, insisting loudly about being fed.  No parental response was forthcoming from the adult on a shrub some distance away. So eventually, the youngster ventured out into the field, looking about with curiosity. Seemingly satisfied with this move toward independence, the adult flew in to feed the youngster. And then they shared the bush a while until the adult flew farther off again. (Click on slideshow’s pause button for captions.)

Two groups of Mallards (Anas platyrhynchos) were escorting their young around the Center Pond. In one group, two males and a female floated along with a small juvenile. The males are now in their late summer “eclipse plumage” which makes them look very much like the females – except that the males have yellow bills, while females’ bills are orange and black. The males will change back to their glamorous, iridescent green head feathers later in the fall when Mallards choose their mates for next spring. I guess these two males on the right were sticking close to this female just in case she made an early decision!

Nearby, a female Mallard escorted her four youngsters with no male attention at all.

A male Northern Cardinal (Cardinalis cardinalis) seemed remarkably calm at my approach as he concentrated on gathering seeds in his beak. Usually they dash off at the first sight of me when they’re on the ground. He wasn’t crushing the seeds, so I assume he had a nest nearby since cardinals can have up to four broods in a season. That’s a lot of parenting in just a few months.

A male cardinal who seemed to be gathering seeds to take to his young rather than eating them right away.

A male American Goldfinch (Spinus tristis) plucked buds from native Canada Goldenrod  (Solidago canadensis) which is just beginning to bloom. He may have been feeding his young as well, since this is the nesting season for goldfinches.

While Adults Molt, Young Birds Forage on Their Own

Many bird species molt from mid-August until mid-September, including Field Sparrows, Downy Woodpeckers, House Wrens and many others.  The Eastern Kingbird, featured feeding its young above, doesn’t molt until it reaches its winter territory in South America. It’s occurred to me that since birds go into hiding during the molt, perhaps their young have to be a bit more independent sooner than other birds. Just a guess. In any case, a lot of young birds are out and about, clumsily trying to forage on their own.

I saw what I think is an adult Song Sparrow (Melospiza melodia) just beginning its molt. The bird’s feathers looked oddly fluffed out and it was picking at its breast in a persistent way. It might be a male since they molt a bit earlier than females. Below, a group of young song sparrows hopped along the trail, seeing what they could find in the grass before flying up into small trees nearby.  (Click on photos to enlarge; hover cursor for captions.)

Downy Woodpecker adults (Picoides pubescens) are molting now too. The Stokes Guide to Bird Behavior (Vol II) says “[Downy] Fledglings in general can be told from adults by the clearly new, white feathers on their breast. Adult have gone in and out of the nest hole hundreds of times by this stage and look very worn, with bits of black showing through their white breast feathers.” The feathers on the young female I saw looked wonderfully fresh as it tried to drill into a branch, so I’m guessing it’s a foraging juvenile.

Down at the Center Pond, a Green Heron rested calmly on a log. Since spring, I’ve repeatedly seen a Green Heron in that very place, so I’m thinking it’s a mature bird. Cornell contends that Green Herons are sometimes found in colonies. But I’ve never seen more than one of these solitary birds at a time.

The same heron flew up onto a bare limb, staring into the water.

Two other solitary birds could have been adults or juveniles. It’s hard to distinguish with the House Wren and the Black-capped Chickadee once they’re out on their own. The House Wren may have been a youngster since it was clearly curious, but the Chickadee appeared to be a sophisticated contortionist as it probed a stick for insects.

Glorious Wildflower Color, Exuberant Vines and a Few Pretty-but-Toxic fruits in the Woods and Shady Wetlands

Though wildflowers are not generally as numerous on the shady paths of Bear Creek, you don’t want to miss them. So keep an eye out for their exotic shapes and vivid colors shining out of the greenery as you make your way, especially near wetlands. I just learned from Wikipedia that the Jack-o’lantern mushrooms (Omphalotus olearius) below are even bio-luminescent and their gills glow faintly green in the dark when they’re fresh! Hence the name, eh?

Native Wildflowers and Grasses Bask in the Sunlight of the Meadows and Native Gardens

A spray of Purple Coneflowers in one of the native gardens

In the native gardens, the center of the parking lot, and scattered across the sunny meadows, native wildflowers bloom among the Canada Goldenrod and the Queen Anne’s lace. The monarchs seem to be enjoying them. A female sipped nectar from the Purple Coneflower and a male spread his beautiful wings on the Joe-Pye. (The field marks for males are bulges in the veins on their hind wings.) Here’s a sampling:

A Quarter-sized Creature Dons a Bubble Disguise

One cloudy afternoon, my husband spotted a very small clump of bubbles, green Water Meal  (Wolffia coumbiana) and Duckweed (Lemna minor) moving slowly around the water of the center pond near the dock.

A moving patch of Water Meal, Duckweed and bubbles on the Center Pond caught our eye.

At first only the yellow/green striped head of a tiny Painted Turtle (Chrysemys picta) peeked out of the bubbly mass.

The tiny head of a Painted Turtle emerged from the bubbly greenery floating in the pond.

At last, we could see this tiny creature – a turtle about the size of a quarter – who’d found a nifty disguise to wear while munching on the Water Meal and Duckweed greenery that covers the pond. I’m betting on this little one to survive to adulthood!

A Painted Turtle – about the size of quarter! – brings its head and shell into the sunlight.

Perhaps when this baby gets a little bigger, it can join the Painted Turtles who hang out on this log at the east end of the pond almost every warm day. Last Saturday, this group seemed to be doing a slow motion version of the Hokey-Pokey (“You put your left leg in, you put your left leg out”), except for that one member who is not quite with the program!

 The Delight is the Details

Western slope of Bear Creek in mid-August

Meadows like the one shown above on the western slope are an eye-full on a summer day. The sweeps of green, yellow and white against a blue sky soothe the spirit like a cool hand on a fevered brow.  Soak it in.  You can feel yourself unwinding.  Then look a little closer.  So much of the delight in nature comes from noticing small things – like the turtle in its bubble disguise, the scarlet cardinal flower shining in a shady wetland, or a parent bird feeding its young on a leafy branch. Like any great work of art, there’s always more to see in nature’s landscapes than what comes quickly to the eye. So perhaps spend a few quiet minutes looking down into the water or into the tall grass. Scan the treetops through your binoculars. The smallest discovery can add just a little more joy to a walk in the park.

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.

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?

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

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?
