This week, Stewardship Manager Ben VanderWeide, Stewardship Specialist Alex Kriebel and a team of trained volunteers created a controlled burn around the sports fields at Marshview Park. Our native plant species are adapted to fire after living for thousands of years with fire on the landscape. While lightning-sparked fires probably occurred occasionally, most fires in the last few thousand years were sparked by humans. The Native Americans in southern Michigan regularly used fire to clear and fertilize land for agriculture and to attract deer and other wildlife with tender, new growth, an early method of herding. As a result, our grasses and wildflowers have evolved to thrive after a burn. In fact, some grow only sparsely until a fire triggers them to emerge, bloom and seed. And luckily, many of the invasive species in our parks, which didn’t evolve with burning, are weakened by fire.
The burn process begins after the crew reviews safety procedures and checks the wind, making sure that weather conditions allow the smoke to rise as quickly as possible to minimize effects on neighbors. Then fire breaks are created or double-checked where necessary by mowing or raking around the edges of the burn area. This gets rid of fuel that would allow the fire to spread where not wanted. In the case of the sports fields, the green grass and paths provided ready-made fire breaks.
Some members of the fire crew, under Ben’s supervision, use drip torch canisters to spread fire, creating a low creeping flame.
Others carry water tanks on their backs to spray trees or bushes that need protection and to put out all smoldering embers when the burn is complete.
The result will be burgeoning growth of native plants, including wildflowers and grasses. After the first controlled burn in spring of 2016, Foxglove Beardtongue(Penstemon digitalis) made an appearance at Marshview Park. Yellow Coneflowers (Ratibida pinnata) burst forth in the summer along with the Compass Plant (Silphium laciniatum), whose huge leaves follow the sun during each summer day. (Photo below by Aaron Gunnar of inaturalist.org) And in autumn, New England Asters(Symphyotrichum novae-angliae) made a glorious, royal purple show around the edges of the sports fields while Little Bluestem (Schizachyrium scoparium), a native grass, filled the parking lot islands with its graceful russet stems. (Use the pause button if you can’t see the captions).
And with these native plants come insects that nourish birds and other native wildlife, while the increase in beautiful butterflies delights the human eye. So, yes, controlled burning paradoxically helps us restore the wild diversity of beauty that is Oakland Township’s natural heritage.
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, GreenHerons (Butorides virescens) foraged and flew at Lost Lake. On my first visit, a young Green Heronstood 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.
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!
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 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.
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
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.
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!
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.

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

Late summer is always a time of transitions, but this year was particularly dramatic. Bear Creek’s meadows baked for weeks under a blazing sun. The marsh dried completely, stranding an over-heated young snapper that struggled through a tangled mat of exposed vegetation. Heat finished off blossoms as some wildflowers began to seed earlier than usual. And then in mid-August, the rains came – downpours, thunderstorms and off-and-on showers. You could almost hear the gulping of plants and trees swallowing the moisture through their roots. Snappers again cruised just below the shallow waters of the marsh. Life rallied. As always, nature just coped and moved on.
Life in the Hot Sun of the Old Fields
The Old Field on the western edge of Bear Creek is quieter now. Mating season has ended (except for the Goldfinches), so birdsong has diminished. But one hot, sticky morning, an Indigo Bunting (Passerina cyanea) threw back his head and let loose his double-phrased song from the highest branch of a tree – a favorite perch for male Buntings.
An Eastern Phoebe (Sayornis phoebe) seemed to be listening to its neighbor as it rested between forays over the baking meadows, trying to snatch a few unsuspecting insects.
A juvenile Yellow-bellied Flycatcher (Empidonax flaviventris) posed quietly among the branches of smaller trees on the Western Slope. Expert birder, Ruth Glass, tells me that this little bird probably arrived from Canada or northern Michigan and is now migrating down to the Caribbean. Quite an adventure for a small bird!
Near the moist bottom of the slope one steamy morning, I spotted a lump on a leaf. A newly metamorphosed Gray Tree Frog (Hyla versicolor) was sleeping on a Common Milkweed (Asclepias syriaca). I’m afraid I woke it with my camera. The U of M’s Bio-kids website says they are “almost always bright green right after metamorphosis [from tadpole stage] and they stay this way for some time before taking on their adult coloration.” These frogs can sleep in the open during the day, using their camouflage to protect themselves; they don’t dehydrate quickly like other frogs. Isn’t it just the best little creature?
While birds foraged from the trees, the insects below braved the blazing sun to look for their own sustenance. In the grass on the Western Slope, a Common Buckeye butterfly (Junonia coenia)seemed to searching the bottom of grass stems. I’ve read that they sip nectar but often look for fluids in moist earth. Perhaps it was hoping for dew on a hot morning in August.
Higher up on the western path, where the land was drier, beetles probed blossoms looking for food. On the left, a non-native Seven-spotted Ladybug (Coccinella setempunctata)searched diligently for aphids, a favorite food. In fact, these beetles were brought here to combat aphids, but as a result, they’ve outcompeted our native ladybugs whose numbers have declined. On the right, a Soldier Beetle (family Cantharidae) may also be pursuing aphids, though it also eats pollen and nectar. (Hover cursor for captions; click on photo to enlarge.)
In the trees near the top of the Western Slope, a sparrow fluffed its feathers in thin shade. It’s hard to identify juvenile sparrows but with its pink feet and bill, I’m guessing this is a juvenile Field Sparrow who hasn’t yet reached full adult plumage when it will have a more distinct eye ring and a clear breast.
American Goldfinches mate in August, much later than other birds. On one hot visit, a female repeatedly rode drying blossoms of Queen Anne’s Lace down to the ground to forage for seeds, perhaps to feed her young – or her hard-working self! Unlike many seed-eating birds, the Goldfinches don’t switch to bugs when breeding. They are strictly vegetarian.
Nestlings of other birds are transforming into curious fledglings. One afternoon, a young, female Eastern Bluebird (Sialia sialis) perched high in a snag (standing dead tree), her spotted breast only halfway transformed into adult plumage.
Wildflowers felt the impact of the fierce sunlight. A Jewel Weed blossom near the pond dried in the heat, while others took its place in the dappled shade. And up on the top of the southern hill, the Yellow Coneflowers (Ratibida pinnata) dropped their petals and began the seeding process in the dry heat.
Sturdy Prairie Dock blossoms, looking like little suns themselves, began to dry out as well as they towered over the wilting Coneflowers.
A female Black Swallowtail hovered just off the sun-drenched Eastern Path, looking restlessly for just the right blossom. Folding its dark wings may help it cope with the sun’s heat.
Patrolling for food, a Ruby Meadowhawk dragonfly rested momentarily on a leaf, its clear wings shimmering in the hot sunlight.
The northeastern edge of the Old Fields evidently stayed moist despite the heat and several “wet-footed” plants took full advantage of the bright sunlight. Joe-Pye (Eutrochium maculatum) spread its dusty pink blooms out across the field instead of appearing as widely distributed single plants as it often does here.
Other native wetland plants fringed the same area. The trio below includes bright pink Swamp Milkweed (Asclepias incarnata) with its green stems, Joe-Pye with dusty pink blossoms and purple stems and Boneset (Eupatorium perfoliatum) with its white blossoms and leathery leaves.
Below center, the native Bumblebee (genus Bombus) sips nectar from the Swamp Milkweed with its long tongue and on the left, is a closer look at Boneset. Odd name, eh? Evidently early herbalists noticed the way the stem seemed to rise right through the clinging leaves reminding them of a splint around a bone. So its leaves were wrapped with bandages around broken bones. Native Flowering Spurge (Euphorbia corollata) on the right also thrives here as it does in various spots along the Paint Creek Trail.
Sheltering in the Shade
Near the wood edges, I found mammals and insects enjoying the shade. Following a shining strand hanging before our eyes, my husband and I discovered a very tiny white spider escaping the bright sunlight on the underside of a leaf. I tried but couldn’t identify it, despite that wonderful design on its abdomen. We wondered if that brown ball was an egg sack. Anyone know this tiny creature’s name?
And, as usual, damselflies moved in and out of the shade at the edge of the Oak-Hickory forest. I’m guessing, based on its bright blue head, striped thorax, and very pale abdomen, that this one may be a female Bluet (genus Enallagma) or a recently hatched one. But since there are at least 17 species of Bluets in the Midwest, I’m not sure which one this is. Again, I’m open to your ideas.
A White-Tailed Deer (Odocoileus virginianus) sat calmly on the shady site of a dried vernal pool, while her fawn dutifully hurried off into the bushes as I paused for the photo.
And an Eastern Cottontail paused in a shady spot along a trail one hot morning as well.
And Then the Rains Came…
What a relief when heavy rain came to refill the wetlands and ponds at Bear Creek Park! After watching that young Snapping Turtle (Chelydra serpentina) struggling through vegetation in the dry marsh, it was a relief to see two Snappers feeding and cruising just below the surface in the cooling water provided by the rain.
The bright sun and rain caused Common Duckweed (Lemna minor) and Water Meal (genus Wolffia) – often mistaken for heavy algae – to form thicker mats across wetlands around the park. At the Playground Pond, I heard a plop! one afternoon and saw just the head of a Muskrat (Ondatra zibethicus) moving through the juicy green surface. Luckily, its ears close when it enters the water! When swimming, it uses its tail to propel itself with the help of its webbed back feet.
Once the Muskrat dove, I noticed other denizens of the Pond nicely camouflaged in duckweed and water meal as well. Here are two turtles and a frog on a log decked out in greenery.
Quivering in the duckweed near the boardwalk made me look down to see a whole collection of small Green Frogs (Rana clamitans). Each of those individual spots on the leg of the frog below is a water meal plant! Ducks do love this plant, by the way. Sometimes they just dip their bills in and move along, scooping it up.
In the wetland just north of the Playground Pond, a particularly beautiful native plant is blooming in the moist shade, Cardinal Flower or Red Lobelia (Lobelia cardinalis). Last week when I took an out-of-town friend to the park and left my camera at home, we watched a Ruby-throated Hummingbird (Archilochus colubris) sipping at a tall stalk of this scarlet beauty. I came back for its photo the following day – but no Hummingbird then, I’m sorry to say!
We also spotted two Barn Swallowsperched quietly in nearby trees. No camera again! The next day, they were swooping madly across the meadows, their bills open, enjoying the swarms of insects that had hatched after the rain. One perched for a moment in a snag over the wetland and I got this quick photo of it from below.
As the water rose in the Center Pond, tiny Painted Turtles (Chrysemys picta) appeared on nearly every log. Here’s a silver-dollar-sized one trundling along as it explores its world like any youngster.
This week, a Green Heron (Butorides virescens) dropped into the bushes at the western edge of the pond. It kept a close eye on the water, when it wasn’t actively preening with its long, extendable neck. Green Herons are expert hunters of both fish and frogs. I wondered if the absence of July’s huge number of green frogs was attributable to the drought or this multi-colored fisher. (My apologies for the slightly pixelated photos caused by aggressive cropping so we could see it up close.)
Yes, it’s been a hot, sticky and then rainy summer. But we’re all in this together – animals, birds and plants. The natural world provided a gentle reminder that change, even dramatic change, is an inherent part of being alive. Summer may be waning now but the beauty around us isn’t. Surprises await our arrival every day, no matter what the weather.
P.S. More Native Beauties Blooming along the Paint Creek Trail!
The trick about blogging during the summer is that so much happens all over the township, all at once! Keep an eye out for these special native wildflowers blooming for just a short time in the Wet Prairie on the Paint Creek Trail. The shallow water table in this meadow provides a perfect spot for these fire-adapted beauties. The field is dotted with the purple fireworks of Cylindrical Blazing Star (Liatris cylindracea), the striped elegance of Grass of Parnassus (Parnassia glauca) and the delicate, spotted petals of Mountain Mint (Pycnanthemum virginianum). Don’t miss them!

Last week, we explored nature in Bear Creek when it was a working farm 75 years ago. I thought it would be interesting to continue following its history to learn how it became our first publicly protected park. And the source for that information was the “mover and shaker” who envisioned turning this abandoned farm into Bear Creek Nature Park and helped make it a reality – Parks and Recreation Commissioner Alice Tomboulian.
Many thanks to Alice and her husband Paul for sharing their knowledge of Bear Creek 45 years ago – and their photos below that I’m using with their permission! Also thanks to Parks Director Mindy Milos-Dale for great info and photos of the Grand Opening of the new park developments in 2003!
1969: Exploring an Abandoned Farm
Much had changed since the 1940’s when the Comps family lived on the farm. With no animals grazing, the grass in some Old Fields had grown tall, while rental farmers raised corn in others. The county had widened Snell Road, taking out the old sugar maples that once graced the front of the farmhouse. The county had also straightened Gunn Road, eliminating a steep curve that went around the far north of Bear Creek marsh by building a new straight crossing with a metal culvert. Sometime in the 60’s, the old farmhouse burned, leaving today only a remnant of an outdoor grill built by George Comps’ father in the 1940’s or 50’s from stones on the property. (Hover over photos for captions. Click on photos to enlarge.)
When Alice and Paul Tomboulian and their family moved to Oakland Township in 1969, the land that became Bear Creek Nature Park was abandoned farmland still owned as an investment by Mr. Devereaux of the Richard C. Devereaux Foundation in Detroit (now of Bloomfield Hills). The Tomboulians were naturalists and lived across from this lovely piece of land. Alice was a volunteer at Seven Ponds Nature Center in Dryden and Paul headed the department of Chemistry and Environmental Health at Oakland University. They recognized the importance of those 107 acres – the marsh, the wetlands, the plants and wildlife – for conservation and preservation. In those days, children and their parents exploring empty land was common and not thought at all to be trespassing. So the Tomboulian family skated on the pond near Gunn Road and explored the woods and fields.
Early 1970s to 1977: Nature Study at Bear Creek
Alice and Paul Tomboulian and their three children used the land that would become Bear Creek as a perfect spot for nature study. Even Alice’s stepmother joined in! Exploring the marsh, for example, took some gusto in those days before the docks were available for observation. So Alice and her stepmom waded in, fully dressed in old clothes, to explore the reeds for coot nests and other denizens of the marsh. Along the way, of course, they also picked up the same kind of trash my husband and I retrieve in the park from time to time to this day!
One day Alice heard a chain saw roaring across the road and hurried over to see who was cutting down trees. It turned out to be the landowner, Mr. Devereaux. Rather than questioning her interest, Mr. Devereaux was pleased that someone was watching over and protecting his land and gave his permission to explore and later, granted permission for Baldwin School field trips for nature study. Soon school children, their parents and teachers began arriving through a narrow path from Collins Road, which today is a much wider, developed path from the Township Hall. The children below and in the photo at the top of the blog, some sporting “Ranger Rick” neckerchiefs, would be in their fifties by now.
On that field trip on a sunny June day in 1969, the children did a bit of exploring around the pond, though of course no viewing from a deck was possible since none existed. Note the difference between 1969 and now. In 1969, the northern side of the Center Pond was edged only with tall grass – most of it non-native grazing grasses and native reeds. Now the north side of the pond is surrounded by thickets of some native and many non-native invasive shrubs .
Here’s another group of Baldwin school children coming down the Eastern Path in June of 1969. Then a narrow foot path wound down through the eastern Old Field where the grass planted to feed the cows was starting to grow tall.
Now a wider, developed trail follows the same path but over the years, thanks to the stewardship of the Parks and Recreation Commission, native Canada Goldenrod and other native wildflowers have made a big comeback. Black-eyed Susans, Coneflowers, Prairie Dock and Common Milkweed, beloved by Monarch butterflies, live peaceably beside non-native wildflowers like Queen Anne’s Lace and Ox-eye Daisies.
Yellow Cone Flower is a perennial native wildflower.

In 1974, an ecological survey of Oakland Township by Paul Thompson of the Cranbrook Institute of Science confirmed the importance of the land that is now Bear Creek. He briefly described the area that is now Bear Creek. as having “an excellent cattail marsh…several dozen muskrat lodges…an oak hickory woodland of moderate sized trees, and a number of small woodland ponds.”
1977 – 2003 Bear Creek Becomes a Park, Wild and Undeveloped
In the early 70’s, Alice and Paul Tomboulian and their children continued their nature study on the land that was to become Bear Creek Nature Park. Mark, the Tomboulian’s younger son, was a born naturalist. Over the years that he explored Mr. Devereaux’s land, he kept a list of every plant, animal and bird he saw. Here Alice and her three children are doing some nature study at Bear Creek marsh in the 1970’s. (Photo from an article in the Pontiac Press, now the Oakland Press.)
In the ’70s, Alice was serving on the Oakland Township Board of Trustees. Armed with her own nature study and her son Mark’s wonderful list of the wildlife and plant life in the marsh, she proposed to the Parks Commission the creation of the township’s first park by buying Mr. Devereaux’s property. And in 1977, The Oakland Township Parks Commission purchased the 107 acres of land which is now Bear Creek Nature Park using $305,000 from the Parks Millage Fund.
At the time, township residents preferred keeping the parks with access only by footpaths. But problems needed to be solved in Bear Creek Marsh. Over the years, the metal culvert under Gunn road installed in the 1940’s had rusted and partially collapsed. The drainage became blocked with runoff and debris from roadwork and development. Water flooded the marsh, creating unnaturally high water levels, “sometimes giving the appearance of a 8 acre lake,” as Paul Tomboulian puts it. The high water was drowning a very special native habitat relied on by native wildlife. (Hover cursor over photo on right for caption.)
Alice, the PRC, and the Township worked with the Oakland County Road Commission for 16 years to correct this problem. According to Paul Tomboulian, the old culvert eventually “was replaced with a new 78-foot long pipe in 2003, new water levels were set, and erosion control measures near Gunn Road were installed.” Now, the water level has returned to more normal levels and bulrushes, cattails and marsh wildlife are returning to Bear Creek Marsh.

September 2003 – Bear Creek Becomes a Fully Developed Nature Park
Later, when the Parks Commission became the Parks and Recreation Commission, the PRC moved to make Bear Creek Nature Park even more accessible to the public. With the approval of commission members, Parks Director Mindy Milos-Dale sought out and wrote the Township’s first grant from the Michigan Natural Resources Trust Fund. The grant proposal was accepted and paid for 44% of the cost of facilities improvements at the park. They included ADA accessible limestone trails, wooden boardwalks, docks and overlooks in wetland areas, a picnic pavilion, a children’s play area, a gravel parking lot and restroom facilities. The remaining cost was matched from Parks Millage Funds.
After all the careful planning and financing was done, Bear Creek Nature Park had its Grand Opening on September 27, 2003. Visitors, like us today, enjoyed the Old Fields filled with the gorgeous orange and purple of fall’s Canada Goldenrod and New England Aster. They could hear Canada Geese and Sandhill Cranes crying overhead as they headed south. Visitors watched water birds from the observation deck as they do today. Muskrats and snapping turtles swam peacefully in Bear Creek Marsh.
What a journey! We owe a debt of gratitude to the vision, consistent effort and careful study of the Tomboulians, PRC commissioners over the years, Parks Director Milos-Dale and the support of many park-loving Trustees whose foresight and careful planning protected the marshes, meadows and woodlands of Bear Creek for all of us who enjoy its very special beauties today.
Before European settlement, our special area of Michigan was actually an Oak Savannah with large expanses of tall waving grasses,
widely scattered, spreading oaks
and other native trees, shrubs and prairie wildflowers. During the spring and summer, ground-nesting birds like the Northern Bobwhite Quail (Colinus virginianus) settled among tall grass stems, producing young. Bobolinks (Dolichonyx oryzivorus) sang their burbling song while swaying on grass stems. The Eastern Meadowlarks (Sturnella magna) whistled their slow song from perches in low shrubs. Later, in the 1800’s, non-native game birds like Ring-necked Pheasants(Phasianus colchicus) were introduced and took advantage of the tall grass for cover.
On November 14 and 15, Oakland Township’s Stewardship Manager, Dr. Ben VanderWeide, took a huge step forward in prairie restoration on 20 acres of Draper Twin Lake Park and another 18 acres in Charles Ilsley Park. The hope is that residents will be able to experience the land as it may have looked before and that native residents – birds, animals, grasses, wildflowers, shrubs and trees of the prairie – can return, adding more rich diversity to the plants and wildlife of Oakland Township.
The process began in the summer of 2014 as crews working with Dr. Ben began removing the non-native and invasive species that had taken over the land after farming had ceased. This meant long hours of cutting woody invasive trees and shrubs like Autumn Olive, Multiflora Rose and Glossy Buckthorn which had quickly colonized the open land, and then treating the stumps to prevent re-growth. The process continued this summer until one beautifully rolling 20 acre field was finally prepared for planting in Draper Twin Lake Park.
Two other rolling fields of 5 and 13 acres at Charles Ilsley Park were also cleared and prepared.(Click on double photos for larger view. Rest cursor on photos for captions.) Two more 15 acre fields are being prepared for planting in 2016 and 2017.
Dr. Ben sought out a U.S. Fish and Wildlife grant to purchase wild seed for these areas and then carefully selected a list of plants suitable for our specific sites. Township residents will need to be patient, since prairie flowers spend their first two to three years putting down deep roots. These deep roots help prairie plants survive drought conditions or fire to which they became adapted over thousands of years of fluctuations in climate and periodic fire. In fact, carefully controlled prescribed burns will be used periodically on these prairies in the future because regular burning helps native plants thrive and thwarts non- natives who are not adapted to it. Some native plants even require fire in order to bloom!
A few flowers will begin to appear next spring, but the prairies should really start blooming vigorously by the spring and summer of 2018. Here are just a few of the prairie grasses and wildflowers that will be gracing our prairies then. (Click on photos to enlarge them and hover your cursor over the photo for plant names.)
Along with these more familiar native plants, Dr. Ben also included grasses and flowers that used to bloom here but that we see less often now. Click on these links to see Foxglove Beardtongue(Penstemon digitalis), Wild Lupine(Lupinus perennis), andSky-blue Asters(Symphyotrichum oolentangiense). And that’s only a sample of the 36 species of plants Dr. Ben ordered!
With those plants up and growing, our parks can attract more butterflies and native prairie birds like those mentioned above or maybe other special species, such as the Northern Harrier (Circus cyaneus), or Henslow’s Sparrow.
So that November weekend, Jerry Stewart from Native Connections brought equipment designed for planting native seed. Jerry first carefully calibrated the seed drill for the seed type, planting rate, and depth. He then loaded seed in the hoppers and was ready to go.
Four of our former OT stewardship technicians, who had worked hard to clear land for this project, joined Dr. Ben and Parks Commissioner Colleen Barkham (not pictured) to see the moment when the seed finally went into the ground. The former technicians are now finishing up school or pursuing careers in various environmental fields.
Now the native seed is in and next spring, sturdy native wildflowers and grasses will begin sinking their roots deep into the soil, a survival strategy that will take them 2 or 3 summers. And then in year three or four, we will be able to watch prairies in full bloom again in Oakland Township. As time passes we hope the wildlife return – butterflies floating above swaying grass and native wildflowers, while the Bobolinks sing and the “Bob-White!” whistle returns to grace the summer months. Dr. Ben shared some photos taken on the Flint Hills prairie in Kansas (where he completed his doctorate) in order to help us dream until then.
The Walnut Lane in the center of the park is a hangout for avian adolescents this time of year. Every few feet you hear or see another fledgling sparring with siblings, practicing a song or poking about for food on their own as their tired parents retreat from constant feeding. Below I’ve provided links to Cornell Ornithology Lab photos of the adult birds so you can see how the juveniles differ from the adults in appearance.
The numbers of the most successful park predator keep growing – and no, it’s not coyotes! And native wildflowers love the second half of the summer (yes, we’re already there!) and are showing their colors everywhere you look.
Avian Adolescents – and one baby…
I have to begin with a nestling. Remember the female Cedar Waxwing (Bombycilla cedrorum)on a nest from last week’s post? Well, this week her nestling stuck its little half-masked head above the nest edge so I got to see a Waxwing nestling for the first time! It sure doesn’t look like the elegant bird it will be in a few weeks! It’s still mostly mouth and that beak still looks soft, doesn’t it?
Amusingly, adolescent birds have the same awkward, gawky, not-quite-put-together look of a human adolescent. And like them, they seem to hang out together – this year, in the lane of Black Walnuts. Here’s a juvenile Gray Catbird (Dumetella carolinensis), a bird which when it matures is sleek with gray feathers and a black cap. This youngster is in shadow, but you can see he still has downy fluff that makes him look a bit like he’s wearing baggy pants!
And here’s a young Rose-Breasted Grosbeak (Pheucticus ludovicianus). The juveniles look like their brown-and-white mothers, but I believe that little red dot under this one’s wing tells you it will eventually look like the stunning male at this link – black and white with a hot pink bib at his throat.
This young Downy Woodpecker (Picoides pubescens) looks a bit scraggly, but seemed to be finding all kinds of things to peck at or eat on a walnut tree. I’m thinking it’s just a gawky adolescent.
Look at the lovely pattern its wing made as it flew off.
And here’s a home photo of an adult Downy to show how much more “together” an adult downy can look!
By the way, if you live in a house with wood siding as we do, you may be frustrated by a male Downy drumming on your house. According to Cornell Lab, the Downy isn’t feeding, which means you don’t have bugs in the siding. This is the Downy’s way of singing; it uses percussion to attract a mate. Of course, they’re still making holes in your wood!
New Fierce but Fascinating Predators Arrive at Bear Creek!
I’m referring, of course, to Dragonflies. Right now, the BIGGESTof these drone-like insects, called “Darners” (after the large needles), are hatching out of the ponds and patrolling the fields of Bear Creek. They can be three to five inches long and have a wingspan slightly larger than their body. I’m quite confident that this is a Lance-tipped Darner (Aeshna constricta ) we saw Sunday along the western sloping path. Dragonflies are notoriously difficult to identify, however, so feel free to correct me!
I’m quite sure that I saw a Swamp Darner (Epiaeschna heros) zooming over the Old Field off the eastern path earlier this week. Here’s a photo of a non-zooming Swamp Darner from a couple of years ago.
Of course, regular dragonflies are hatching out of the ponds as well. Dragonflies successfully snatch out of the air 95% of their prey, (especially mosquitoes!) and consume them on the wing. Lions, for example, only catch their prey 25% of the time and Great White Sharks only 50%, so we’re talking about very successful predators here! How about this face?! This is a common dragonfly, the White-Faced Meadowhawk (Sympetrum obtrusum.)
On a sweeter insect note, we also were gifted with the sight of two Great Spangled Fritillaries (Speyeria cybele) mating. We couldn’t determine which gender is larger, but there is quite a size difference! Here are two photos, as they synchronized opening and closing their wings.
Native Wildflowers Assert Themselves as the Summer Warms
The second half of the summer ushers in a big bloom of native wildflowers. In the hot sunlight of high summer, prairie flowers flourish, since long ago, much of Oakland Township’s land was prairie. I recommend bringing your lunch, sitting on the hilltop benches at the south end of the park, and just enjoying the Yellow Coneflowers (Ratibida pinnata) as they sway in the wind.
And right across the path, another native, Black-Eyed Susans (Rudbeckia hirta) bloom in happy profusion.
Large lavender swaths of Wild Bergamot (Monarda fistulosa), also known as Bee Balm, keep company with these other two. This wildflower is certainly a “balm” to bees since you rarely see a group of them without seeing bees busily probing the hearts of these fun, “bad hair day” flowers! Like the native plants I mentioned last week, Bergamot has been considered a medicinal plant and was used as an antiseptic by Native Americans.
CAUTIONARY NOTE FROM OAKLAND TOWNSHIP PARKS AND RECREATION: DO NOT pick or consume wild plants in our parks. In addition to being potentially poisonous, many wild plants are endangered because of over-harvesting. Oakland Township ordinances prohibit removal, destruction, and harvesting of plants within parks. Leave plants for wildlife and other park users to enjoy!
In the native flowerbed near the shed, some glorious plants are blooming for your enjoyment as well. Look at these lovely native False Sunflowers (Heliopsis helianthoides).
And tall plumes of native Meadowsweet (Spiraea alba), standing in the sunlight, hum with pollinating bumblebees.
Nearby, a native plant with an exotic flower also grows tall in the flowerbed by the shed. It’s Wild Senna (Senna hebecarpa) and with a flower like this, it should be called wild!
And look how they grow in profusion along the stalk of the plant!
And here’s one last exotic-looking native shrub that I’ve always loved. My parents backyard which backed up to the Paint Creek Cemetery used to be full of native Staghorn Sumac (Rhus typhina) which always looked to me like it belonged in the tropics! No, it’s not poisonous. Here’s a link where you can see that Poison Sumac looks completely different and lives in wet areas, unlike this sumac that is at the edge of the woods next to the western sloping path.
One of the tallest native wildflowers is just barely starting to bloom among the Yellow Coneflowers at the top of the southern hill. Prairie Dock has HUGE leathery leaves and can reach 10 feet in height. You can see the tall stalk with its round buds towering over the other plants in the sunlit native flower bed near the shed as well.
Here’s the first beginnings of a bloom out by the benches on the southern hilltop.
So bring a lunch and/or a friend and hang out with the avian adolescents on the lane this week or simply sit on the benches at the top of the southern hill and watch the Yellow Coneflowers sway and listen to the hum of bees in the Bee Balm. You deserve to nourish yourself with a lazy afternoon at Bear Creek Nature Park!
