Bear Creek Park: Eggs to Fledglings, Caterpillars to Butteflies, Everything Just Keeps Growing!

 

Spiderwort, a native wildflower, blooms in profusion even in the garden at the center of the parking lot at Bear Creek Nature Park!

June is an easy month to love. In the early weeks, May’s buds transformed into blooms. Turtles and dragonflies emerged from the ponds. Butterfly and grasshopper eggs hatched into caterpillars and tiny nymphs. May migrators and some year-round birds completed their nests and were busily laying eggs.

And then came really warm days – or even some very hot days this year! –  and by the end of the month, life had quickly moved on. The spring blooms produced their seeds and subsided as the summer flowers began to emerge. Bees buzz along the trails. Dragonflies dominate the open meadows and wetlands. Damselflies, like colorful, winged sticks, pause briefly by the pond and other strange flying creatures hunt in the shade. The fledglings emerge from nests, awkward and downy, begging to be fed by exhausted parents. So much to see that I find myself rushing from park to park, trying not to miss anything! So here’s just a selection of what came my way at Bear Creek Nature Park during the first month of summer.

Early to Mid-June:  Brave Beginnings

The Bear Creek Wetlands in Early June

So much happens near the wetlands as summer begins. Two nests graced either side of the viewing deck at the Center Pond. On the west side, high above the water, a Baltimore Oriole’s (Icterus galbula) carefully woven sack swayed with every breeze, rocking either the female brooding her eggs or a cuddle of nestlings with every breeze. While we birders watched one Wednesday morning, the female arrived at the nest and disappeared into it, followed by the attentive male. This lovely photo of the male arriving at the nest was taken by Ewa Mutzenmore, a member of our group.

He gave us the eye as he leaned in to feed either his brooding mate or perhaps their nestlings.

And then, tail up, evidently unfazed, he proceeded to stuff foraged insects into a waiting beak below.

Tail up, the male oriole feeds his nestlings or his mate who arrived before him.

Ewa, whose Oriole photo is above, mentioned having seen a very large Northern Water Snake  (Nerodia sipedon) swimming away at the pond when she was there last and suddenly Ben VanderWeide, our Natural Areas Stewardship Manager, spotted it! Its long, thick body was wound around the branches of a willow bush just west of the dock. Though not venomous, I wouldn’t advise picking one up or harassing it; it will bite and spray you with musk to defend itself. Unfortunately, Ewa and I both could only come up with a photo of parts of its winding body; it just didn’t move a muscle. But here’s a link where you can see a photo of its dark brown head. The birds are evidently safe from it, though fish,frogs, and salamanders better beware!

The body of a large, but non-venomous, Northern Water Snake wound into a bush limb near the Center Pond.

As I approached the pond on a later afternoon, another impressive predator rose like a submarine from the silvery pond.  A large Snapping Turtle (Chelydra serpentina) up-periscoped to check me out.  Isn’t their snout a curious shape?  It’s more important to be cautious around Snappers when they’re on land than in the water, because they do bite if threatened and have extremely long necks. And generally, they’re on land to lay eggs.

The head of a female Red-winged Blackbird (Agelaius phoeniceus) popped out of the bushes for a look around before she winged down and disappeared into her nest in a small tree just east of the dock. (Click on photos to enlarge; hover cursor for captions.)

 

Over in the playground pond, a tiny (about silver-dollar-sized!) Painted Turtle (Chrysemys picta) climbed onto a log for probably one of its first basks in a spot of sunlight.

As I approached the dock one cloudy day, a lone male Mallard (Anas platyrhynchos) stood forlornly gazing out at the water from a floating log, not a mate in sight.  When he heard my approach, his beautiful head twisted toward me with a  stare that implied he’d prefer to be alone. Then he dropped into the water and glided away.

A lone, male Mallard notices me with some misgivings about my presence.

When he departed, a much tinier male landed on the dock, the Dot-tailed Whiteface Dragonfly (Leucorrhinia intacta), whose name says it all!  I get a huge kick out of his Mickey Mouse-style face.

At Draper Twin Lake Park a few weeks ago, I’d seen the female Dot-tailed Whiteface, who is more elegant, if less amusing.

And one Sunday morning, while scanning Bear Creek marsh, I heard the unmistakable whinnying call of a Sora (Porzana carolina), a bird that tends to be heard and not seen. This secretive bird is evidently abundant according to Cornell Ornithology Lab, but likes to stay hidden deep in the cattails and reeds. Looking at this photo by inaturalist.org photographer by Mike Baird, you’d never guess that such a chunky bird with stubby wings had migrated here from Central or South America! And check out those feet!

Several strangely beautiful insects shelter or hunt in shady spots near wetlands, too.

A male Orchard Oriole (Icterus spurius) appeared for the birders at the top of the southern hill away from the wetlands, though they sometime nest along the edges of marshes and rivers. This poor fellow seemed wildly distracted by some itchy insect, probably Feather Mites (super family Analgoidea) which often infest nests in early summer. He just barely stopped preening for a moment! As a victim of biting midges in spring, I could sympathize!

Sun and Shade Meant Blooms, Juicy Leaves – and More Insects!

The birders saw four Monarch Butterfly caterpillars (Danaus plexippus)  – one of them above – munching contentedly on leaves of  Common Milkweed (Asclepias syriaca). It’s wonderful to know that natural areas management of our parks makes them places where milkweed gets ever more plentiful – and that, as a result,  migrating monarchs find their way here to lay their eggs  for the next generation.

Nearby, the tiniest of Black-legged Grasshopper nymphs (Melanoplus femurnigrumsat quietly enough that I could a good look at this little one, less than a half inch long! It’ll probably molt 4 more times before it reaches adulthood.  Pretty special eyes, eh?

A tiny grasshopper nymph watches the lens carefully as I take a closeup.

Twelve-spotted Skimmer (Libellula pulchella) found a budding stem to be the perfect place to pause and scan us birders and the prey we might have stirred up as we walked among the plants in the parking circle.

In the native gardens near the parking lot and along the Walnut Lane in the center of the park, early June brought colorful blossoms and the seeds of early spring flowers that  were already maturing their seeds for next year’s crop inside their fruits. Such a variety of colors and shapes! (Use pause button for time to read captions.)

A Late June Visit To See What Had Changed

Wow!  The shy flowers of late spring and early summer had been replaced by the big, bold native milkweeds. Monarch caterpillars seem to have finished munching on Common Milkweed leaves and spun their chrysalises; some have yet to emerge and some may already be flying. Butterfly Milkweed (Asclepias tuberosa) is ready to host any number of butterflies this summer. If you’re looking for color in your garden, Butterfly Milkweed’s a nice native choice because it remains an attractive bunch instead of spreading like Common Milkweed – and pollinators find milkweeds irresistible!

Mites must still be giving birds a hard time, though.  This itchy little Blue-Gray Gnatcatcher (Polioptila caerulea) preened just as insistently as the poor Orchard Oriole earlier in the month! This gnatcatcher is small, only a bit larger than a hummingbird and smaller than a wren and can be identified by its white-edged tail. According to Cornell Lab, they sometimes build up to seven nests in a season because they frequently give up a nest due to mites, predators and problems with Cowbirds and others that lay eggs in their nests. Hope this little one persists despite all those tribulations!

On the western slope, an adult Song Sparrow (Melospiza melodia) and its fledgling paused in a bush. The adult looked around checking for trouble, then hopped onto the ground, looking for seeds or insects to feed the youngster. The youngster hopped clumsily in the bush, waiting for its parent return, which fortunately resulted in something to eat!

The American Goldfinches (Spinus tristis) wait until late June or July to begin their families. They will use the fluffy pappus from thistles and other plants to line their nest and they feed on the thistle’s seeds, a favorite food. It looked as though this couple was already making the most of these Field Thistles (Cirsium arvense) that are just getting started.

This pair of American Goldfinches is just beginning its breeding season.

A bit later in the Eastern Meadow, a Halloween Pennant Dragonfly (Celithemis eponina) was coping with a stiff breeze by holding tight and adjusting its wing positions to stay aloft.  This one could be looking for a mate; maybe that’s why it was working so hard to stay visible on a bare perch above the wildflowers.  Once it finds a mate, they’ll both head to the nearest wetland where the female will dip her abdomen into the water, leaving eggs behind.

The Black-legged grasshopper nymphs had changed a bit when I made my last visit. This one now had a bit more black-legged-ness! I assume it had gone through its second molt. I didn’t take a closeup of this one so you could see how tiny these nymphs really are.

The wetlands, as usual, were full of life too. A juvenile Green Frog (Rana clamitans) had left  its youth as a tadpole behind and was sitting waiting for the nearest flying insect at the Playground Pond. The green dots are Water Meal (g. Wolffia) which covers the playground pond along with spots of Common Duckweed (Lemna minor) – aptly named since ducks do scoop up both plants and make a meal out of them!

Nearby, a tiny Amber Snail (G. Succinea) snacked delicately on the seeds of Orchard Grass (Dactylis glomerata). I wonder if those black spots on the blossoms are places where the snail has secreted extra slime to stay attached while eating?

While monitoring a vernal pool at Bear Creek, the crew brought up a tiny Crayfish (family Cambaridae). It was too tiny to determine a species but it certainly had all of the equipment it needed for surviving in its underwater world.  Crayfish molt six to ten times in their first year, so this one has a long way to go before adulthood!

It was the Best of Times, It was the Worst of Times…

Summer is glorious, right?  Who could argue with that?  All the blossoms, birds, whispering leaves and yellow sunlight pouring over it all.  Or as the poet,  e.e. cummings so ebulliently put it, “the leaping greenly spirits of trees/and a blue true dream of sky; and …everything/which is natural which is infinite which is yes.”

But I wonder sometimes if migrating birds, for example, might grouse a bit about cummings’ enthusiasm and ours. Summer is a busy, hard-working time for birds! I’ve become so aware of this by monitoring bluebirds this summer and it’s true of all birds, really. First there are courtship rituals that can involve singing constantly for hours. A diminutive House Wren (Troglodytes aedon) or the Red-eyed Vireo (Vireo olivaceus) may sing their territorial/courting songs a hundred, even a thousand times in a day! Nest-making often involves long days or even a solid week of gathering material and then weaving, or scraping, or even digging a safe place for their eggs. And once eggs hatch, their young sit begging in the nest and later from every branch, crying “MORE FOOD!” Imagine having young every summer, frequently multiple broods of young,  and working constantly to be sure at least some of them survive despite predators of all kinds – plus coping with those miserable feather mites!

And yet, thank goodness, they return to us each year to go through it all because the show must go on! The genes must be passed to a new generation! I’ve come to admire the sheer tenacity of nature in facing the vicissitudes of life without homes in which to retreat at night or when the weather is harsh. Learning more about the threats and difficulties that birds overcome, I’m doubly pleased to see them with their breasts turned to the sun on a cool morning, or to hear their quiet evensong calls around me as the sky grows dark. They seem to still be able to pause now and then from all the hubbub of their lives and just “be” for a few moments. I take that as a lesson for my busy life – and probably yours too.

Back to Bear Creek: Surprise! Unusual Sightings of Birds, Bugs and More

Blog Post & Photos by Cam Mannino

The last two weeks at Bear Creek gifted me with some exciting moments – seeing previously unseen birds, witnessing unusual nesting behavior, watching a turtle struggling to bury her eggs and being surprised by a little butterfly I hadn’t seen for years. So though the blog just visited Bear Creek two weeks ago, I wanted to share the bounty I’m enjoying before the season changes much.

Unusual Birds and the Usual Ones Doing Interesting Things!

As many of you know, I’ve been walking in Bear Creek for 25 years and I’ve watched for owls all that time. They spend their days sleeping right next to tree trunks on high limbs, and despite craning my neck for years, I’d never spotted one. But on the first June bird walk, a fellow birder, Bob Bonin,  spotted one high up in a tree near Bear Creek Marsh. Huge, silhouetted against the morning sky, this Great Horned Owl (Bubo virginianus) wasn’t easy to see, much less photograph. But luckily, I got a few shots before he gave the group an annoyed look, lifted his huge body with his massive wings and flew away. Such a thrill! (Click on arrows for slideshow; use pause button for a closer look.)

A bit earlier that morning, we saw an unusual bird at the other end of the size spectrum. A male Ruby-throated Hummingbird (Archilochus colubris) perched high on a snag behind the Center Pond and turned his iridescent green back to the morning sun. We saw a quick orange flash at his throat but I missed it. The Stokes Guide to Bird Behavior (Vol. I) indicates that males’ throats look brown or black if the light doesn’t hit their necks just right. When I returned on a late afternoon, there he was on the same snag – but this time the afternoon sun caught the edge of his throat which shone gold rather than ruby red. He’s not the most glamorous hummer, but I’m glad I got to see a bit of his gleam.

This male hummingbird’s bright throat only shone for a second in the morning sun, so I settled for the light in his eye and his iridescent green back.
The same male hummer’s throat shone gold in the late afternoon sun.

Near the Center Pond, the birders also discovered the nest of a Rose-breasted Grosbeak (Pheucticus ludovicianus) – with the male sitting calmly, tending the eggs or nestlings. Occasionally, he even sang his lovely tune as he waited patiently. I’d read in the Stokes Guides that male Grosbeaks sometime take on this responsibility, but I’d never seen it. On three separate visits, the male was the only one on this nest – though the female may have relieved him at other times. So, Happy Father’s Day to this dedicated Grosbeak dad!

In a willow to the right of the deck in the Center Pond is a beautiful nest.  It’s cleverly attached between two vertical branches about 20 feet up, ingeniously woven and quite large – maybe 9 inches long. During my first 3 visits, only the female’s black tail cocked behind her was visible from the observation deck. Finally one afternoon, I waded into the grass at the pond’s edge and  caught sight of her hindquarters as she fed her young. And then, I saw a fledgling’s head just above the edge of the nest. Ah, this nest was constructed by a female Red-winged Blackbird (Agelaius phoeniceus) – a somewhat eccentric one since Red-wings normally build close to the water and weave their nests among cat-tails or reeds. She’s quite an architect! The location of this elaborate nest makes it nearly invisible and unreachable by predators. Clever mama Red-wing!

Two nests appeared high in a tree on the Walnut Lane. The barely visible, masked eye of the female Cedar Waxwing (Bombycilla cedrorum) peeked through the leaves that camouflaged the first nest spotted by the birders. Since she sat there quietly every time I visited, I’ve included a photo of a Waxwing from a previous year so you’ll  remember how elegant this conscientious mother bird truly is!

Only the masked eye of the female Cedar Waxwing shows above the edge of her cleverly hidden nest along the Walnut Lane.

Across the Walnut Lane, the birders also discovered the nest of a female Eastern Kingbird (Tyrannus tyrannus) who spent several days building her gauzy, somewhat more loosely constructed nest. She proudly stood above it a few days later as it neared completion. The female Kingbird constructs the nest and keeps the male off it until the eggs hatch. Then both parents feed the nestlings. But even during the egg phase, the male stays on a branch nearby to defend the territory for his mate and young.

Another good provider, a tiny male Yellow Warbler (Setophaga petechia) brought a bright green caterpillar to feed his nestlings or mate. In between feeding trips, he’d let loose with his proud song, “Sweet, sweet, I’m a little sweet.” Impressive dad who can bring home the bugs, singing all the while! Bet the female warbler was as impressed as I was.

An Orchard Oriole male (Icterus spurius) serenaded us from a small tree in the middle of a meadow. His long, melodious song sounded much like the third song recorded at this link.  A few Orchard Orioles seem to come to Bear Creek each year – but they migrate south by mid-July. So keep an eye out and an ear cocked soon in the meadows to the east of the Walnut Lane!

An invisible bird, high up in the tree tops, repeated its melodious warble continuously one warm morning. I’ve never seen a Warbling Vireo (Vireo gilvus); they rarely come down from the heights. But fortunately, a great photographer from the iNaturalist website, Steven Mlodinow, has seen one and generously allows others to borrow his photo. Listen for this warbler’s rich melody all summer long, but don’t be surprised if you never spot this elusive summer resident.

Little Surprises Near the Wetlands

At the northeast corner of the Center Pond, a young Painted Turtle (Chrysemys picta) hurried to cover her eggs one hot afternoon. She’s found a likely spot where Ben had cleared away invasive shrubs a couple of years ago. As you’ll see in the video below, she work really hard with her back legs to get the dirt to move. She’d no doubt have preferred sandier soil! But she was determined to see the job done!

I’ve seen Northern Leopard Frogs (Lithobates pipiens) periodically at Cranberry Lake but never one at Bear Creek. But hearing their snoring call near a wetland, I waded into tall grass and found this one, hiding among the greenery. Glad to know this beautiful frog is at Bear Creek, too.

Ben noticed an  Eastern American Toad (Anaxyrus americanus) toad on the path one afternoon when we went to look at nests.  Normally, I only see brown toads, but Wikipedia informs me that “The color and pattern is somewhat variable, especially for the females. Skin color can change depending on habitat colors, humidity, stress, and temperature…Some toads of this subspecies have a more pervasive red and deep brown color, many with red warts on their bodies.”  So this little toad is probably female and the red description  fits  her pretty well.  I wonder if the unusually hot temperatures had an effect on her appearance?  Hard to tell.

Amazing Insects: A Butterfly I’ve Missed for Years, Favorite Dragonflies and the Skills of Tiny Pollinators

Next year, I’ll be looking for the boldly patterned Baltimore Checkerspot butterflies (Euphydryas phaeton) on June 11 or 12. I’ve only seen them on those two dates, 6 years apart! This year, four of them fluttered at a spot in the trail where water runs under the path – a place I’ve often seen other small butterflies feeding on minerals left by the water. Later in the summer, watch for the communal caterpillar webs of these small butterflies (about 2.5 inches) on the host wildflower Turtlehead (Chelone glabra) where these butterflies lay their eggs during the summer and where the caterpillars first feed.

Interestingly, in the fall, Baltimore Checkerspot caterpillars wrap themselves in leaf litter, overwinter and finish developing in the spring. This seems to be a big year for them – so keep an eye out if you see a small, dark butterfly at your feet.

The Baltimore Checkerspot overwinters as a caterpillar.

Different species of dragonflies seem to appear each week to dance among the budding wildflowers and over the pond. The dramatic, yet quite common Twelve-spotted Skimmer (Libellula pulchella) did indeed skim over the tops of grasses in the Eastern Meadow this week. Dragonflies often land, fly, and then come back to the same dry stalk – so if you miss one in your binoculars the first time, wait a moment and you’ll probably see it in the same place again!

A bright green Eastern Pondhawk (Erythemis simplicicollis) dragonfly clung to a grass stem on the western slope. If it’s a male, it will gradually turn blue over the summer. If a female, it will remain green. Probably this one is newly emerged since it’s hunting in a meadow. When it’s ready to mate, it will rendezvous with others  at the Center Pond.

This Eastern Pondhawk is still in the meadow but will go to the pond when it’s time to mate.

A small Dot-tailed Whiteface (Leucorrhinia intacta) dragonfly posed for a face-on selfie at the Playground Pond before continuing its quest to consume as many mosquitoes, flies and other small insects as possible before the day is out. Love its cartoon-like face and the one yellow dot on its tail that give it its name.

Easy to see why this is called a Dot-tailed Whiteface dragonfly, eh?

 

 

 

 

 

 

 

 

 

 

Pollinators are busy all over the park, feeding and carrying the pollen that will bring us next year’s blooms. This may look like a European Honey Bee (Apis mellifera) but Honey Bees are fuzzy all over and this one just isn’t. So it’s more likely to be a Dronefly (Eristalis tenax), a type of Hoverfly (family Syrphidae), which uses its pattern, slight fuzziness and loud hum to mimic male Honey Bees as a way of protecting against predators. Droneflies cannot sting, but a passing dragonfly probably doesn’t take a chance!

This dronefly (a kind of hoverfly) mimicks a bee’s appearance and hum for protection.

I noticed what looked at first like a tiny wasp on this umbel of a native Nannyberry bush (Viburnum lentago) near the Center Pond. But after a bit of research in Pollinators of Native Plants by Heather Holm, I’m going to guess it’s a female Leaf-cutter Bee (family Megachilidae). It has a wasp-y pattern and shape and it’s collecting pollen on its abdomen and on the top of its back leg (look at those jodhpurs!). Leaf-cutters cut small, neat circles out of leaves, hence the name. They then roll up a single fertilized egg and a chunk of pollen in each circle, forming a solitary, cigar-shaped nest which is placed in a hole in the soil, wood or other structures. Such an unusual nest!

Bring a Friend – or Friends! – to Visit Your Favorite Park

Oakland Township Natural Areas manager Ben VanderWeide leads a group of birders at Cranberry Lake Park

I’ve always loved walking alone in the township parks. I can listen to birdsong, stop to look at something tiny like the Little Wood Satyr butterfly below, or enjoy the fresh scents of wood, greenery, the earth after a rain in silence. Solitary walks are contemplative.

But this particular blog testifies to the special pleasures of hiking with interested friends and family. First of all, they just bring more eyes! I’m always seeing things with the birders or with my husband, that I’d never have noticed with just my two eyes (in this case, the owl, the hummer, the oriole, the male grosbeak in his nest and more). But also their curiosity piques mine. They bring specialized interests and knowledge. They often patiently help me find the bird hiding in a leafy tree (“The center trunk at about 2 o’clock…). It’s a different kind of delight to walk with nature-noticing friends. So if all of this nature stuff intrigues you, take some nature-lovers with you on your next walk. Or consider joining our friendly birding group on Wednesday mornings year ’round. We’d love to have you join us! (The schedule is under “Events” at the top of the home page.)

This Week At Bear Creek: Youngsters Everywhere, My First Monarch and Nature’s Medicine Cabinet.

Well, the sun is shining!  It’s a bit cooler than the usual July (fewer mosquitoes!) but summer is proceeding at  Bear Creek Nature Park nonetheless.

Young are still being born and raised, almost grown fledglings are trying out new skills and all over the park, wildflowers grow leggy from the rain, reaching upward as they compete with neighboring plants for the sun. Among those plants are more that illuminate our local history.

 

Raising Young:

Eastern Chipmunks (Tamias striatus) are “chipping” loud and long.  Females often do this as way to ward off intruders from their territory, though some also believe that they’re issuing a mating call which may be the case this week, since their second breeding season is June to August.   Here’s one sitting on a rock in the sun, doing her aggressive or perhaps  flirtatious best, her small body  twitching with every “chip”!

Chipmunk chipping
A female chipmunk generally “chips” to warn intruders to stay out of her territory or she could be issuing a mating call at this time of year.

And up in the trees, female birds are still sitting on clutches of eggs or warming nestlings on a cool morning.  Here’s a Cedar Waxwing (Bombycilla cedrorum) sitting on her nest.  According to the Cornell Ornithology Lab, she can make up to 2500 individual trips to construct it!

Fledglings are bigger and more confident now.  Here’s a fledgling Eastern Bluebird (Sialia sialis) with his rose and beige breast feathers beginning to replace the brown spotted ones of the smaller fledgling posted last week.

An almost mature Eastern Bluebird will have a rosier breast once all his feathers come in.

As you enter the park from Snell Road, listen for a young Song Sparrow (Melospiza melodia) practicing his trill at the top of a small tree on your right.  He’s been there every time I’ve gone in the last week.  His song’s a little rusty yet and he opens his beak just a bit farther than a mature bird, I think, but he’s catching on! Here’s a link to his “sewing machine” sound – a few squeaks and tweets following by a staccato trill.  I think the second “song button” on the link sounds most like our young Song Sparrow.

Down at the eastern end of the Center Pond, a young Wood Duck (Aix sponsa) floats quietly beneath the overhanging branches of a shrub. There are two siblings keeping each other company there at the moment.

And above the lawn that extends in front of the playground, two Barn Swallows (Hirundo rustica) soared above the clover-covered grass catching insects (mosquitoes, I hope!) on the wing. Though they have cobalt blue backs like the Tree Swallows (Tachycineta bicolor ) I talked about earlier, these agile flyers have rusty red breasts rather than white ones.  I only got a photo of them on the wing so here’s a link to see them up close.

Beloved Monarchs, Long Distance Travelers, Arrive!

At last, I’ve seen my first Monarch Butterfly (Danaus plexippus) of this summer.  Flitting quickly from blossom to blossom, this female searched for nectar from  Swamp Milkweed (Asclepias incarnata) in the eastern Old Field.  Unfortunately, the flowers aren’t open yet, perhaps delayed by  unseasonably cool temperatures.   A Monarch who left Mexico in the spring went through 3 generations to get here, turning from egg to caterpillar to chrysalis to butterfly at each stop along the way – and yet the third generation retains the knowledge that its forebear lived at Bear Creek last year!  If this butterfly’s eggs eventually produce another caterpillar and another butterfly, that lovely creature  will make the whole 2,000 mile trek back to Mexico in one long haul.  Amazing.  Monarch populations were up slightly this year but are still down 90% in the last 25 years.  May this one prosper and multiply!

Nature’s “Medicine Cabinet”: Wildflowers Tell Local History

Last week, I featured  some of the plants that were here when Indians lived in our township, some native wildflowers that probably greeted early European settlers and the non-native grasses and flowers that  were planted by farmers for pasture and silage.  This week, I thought I’d share some of the plants used or brought here by those settlers, some for their reputed medical benefits.

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!

“Worts”:  Plants for Healing

According to Wikipedia,  “A word with the suffix -wort is often very old…It was often used in the names of herbs and plants that had medicinal uses, the first part of the word denoting the complaint against which it might be specially efficacious.”

For example, this delicate little flower on a long stalk growing profusely on the Snell path into the park is called Nipplewort (Lapsana communis) because, some say,  it was thought at one time to increase the flow of breast milk.  It’s a widespread non-native these days!

nipplewort
Nipplewort, an invasive non-native, may have been brought by settlers to our area as a treatment for increasing the flow of breastmilk. Some herbalists still think it works that way today.

I’ve already discussed the beautiful native with the terrible name Spiderwort which folks must have thought of as a cure for spider bites.  It’s still used by herbalists today and is still blooming in the driveway circle at the Snell entrance.

Spiderwort is a “wort” plant that must have been thought useful against spider bites and other skin problems. It’s still used by herbalists for various ailments today.

The most well-known “wort” these days is Common St. John’s Wort (Hypericum perforatum)a plant used as a common herbal supplement around the world.  According to the National Center for Biotechnology Information, it’s been used as an herbal treatment since the time of the Greeks, so  I’m guessing the plant arrived here in someone’s garden for that very reason.  Unfortunately,  this species of St. John’s Wort is  invasive,  poisonous to livestock and also crowds out other plants, including our  native St. John’s Worts, which thus far, I’ve not come across.

St. John’s Wort is used as an herbal supplement but it also toxic to livestock.

A native Bear Creek wildflower thought to be medicinal by herbalists is Heal-All (Prunella vulgaris) .  It was used by Indians to treat superficial wounds and is used to some extent that way in Europe today and for other ailments in Chinese medicine as well.  Fortunately, bees and butterflies like this native plant too!

Heal-All doesn’t quite live up to its common name, but it was used by Indians to treat superficial wounds and is also still used as an herbal treatment in Europe and China..

“Banes”:  Plants for Warding Things Off

And then there are the “bane” plants, which people believed could ward off or even be toxic to other species.  I’ve already discussed Daisy Fleabane (Erigeron species), which is meant to be the “bane” of fleas and may have been used at one time in straw mattresses for just that reason.  It’s prolific in Bear Creek this year, the most I’ve ever seen there!

Daisy Fleabane was thought to be the bane of fleas, of course! Good for mattress stuffing.

And now, growing on the west side of the Snell entrance path, among the trees, is Red Baneberry (Actaea rubra), a native plant with “bane” in its name because it is toxic to humans.  Wikipedia claims it was used to make poison arrows by Native Americans.  So don’t eat them.  You wouldn’t get them down anyway, probably; they’re extremely bitter! They are attractive to the eye though!

Red Baneberry
Native Red Baneberry is toxic but tastes so bitter no one would want to eat it!

Chicory (Cichorium intybus), on the other hand, is neither a “wort” or a “bane.  It may have arrived here as a coffee substitute as it is still used in some herbal drinks.  But farmers could also have planted it as  part of their pasturage for livestock. It’s considered an invasive species since it’s seen all along roadsides, but in Bear Creek, it seems to be coexisting with our native plants.  I have to admit that I love its pale blue color, so rare in nature, and the pinking-scissors edge of the petals.

Chicory, a potentially invasive non-native plant, may have come here as a coffee substitute or as part of planting pasturage for livestock.

And this week, I also saw the white/light pink version of Chicory, which I’ve never seen at Bear Creek before.

A Few Last Minute Native Plants

Before they finish blooming, I want to mention three other humble native plants before their blossoms are entirely gone.  The first might have been named by a woman long ago, Thimbleweed (Anemone virginiana).  The “thimble” is the fruit and it disperses its seeds by tumbling along the ground.

Thimble weed?
The “thimble,” the fruit of Thimbleweed, tumbles in order to spread its seed.

White Avens (Geum canadense), a very modest woodland native is one of the plants that can live near/under Black Walnut trees but it grows elsewhere in the woods of Bear Creek as well.

White Avens appears all over Bear Creek and is one of the new native plants that can live beneath Black Walnut trees.

And lastly, this delicate plant has almost finished flowering for the year.  Now it will start making little burrs that spread by sticking to animal fur or your pant leg!  You’ll spot Enchanter’s Nightshade (Circaea canadensis) along many dappled woodland paths in the park.  It’s no relation to Deadly Nightshade.  It was given its exotic name because it lives in the shade and its genus, Circaea,  was named after the enchantress, Circe, from Greek mythology who supposedly used it in her magic potions.

enchanter's nightshade
Enchanter’s Nightshade is not related to the deadly kind and got its exotic name by preferring dappled light and from being supposedly used in magic potions by Circe, a mythological Greek enchantress.

The woodland paths and sunny Old Fields of Bear Creek still carry memories of our local history in the wildflowers that bloom there.  That idea intrigues me and makes even the most humble plants at my feet more interesting.  Hope it does for you, too.

This Week at Bear Creek: Wildflowers Galore, a Damsel in No Distress, New Birds and Very Small Frogs

This week the native wildflowers are glorious!  You can start admiring them right in the parking lot!  Since Ben and his crew burned the center circle of the driveway, native wildflowers are sprouting there like crazy! And the native beds on either side of the shed are full of blooms.

I’ve enjoyed learning the common names of wildflowers in the last few years.  Knowing names starts a relationship with a plant in the same way that knowing a person’s name makes them more than a casual acquaintance.

This striking,  deep violet-blue native plant with long graceful leaves has an unfortunate name,  Spiderwort (Tradescantia ohiensis).   (People who came up with common names seemingly had no poetry in their souls and  must have thought it cured spider bites).  Look at this beauty up close!

Spiderwort, a native wildflower,  looks wonderfully exotic but has a pedestrian name which may refer to an earlier belief that it was a cure for spider bite.

There’s also this golden flower that I’d never seen in the circle until this year after the burn.  I love the buttery yellow glow and scalloped petals of Sand Coreopsis (Coreopsis lanceolata) and so does what looks like a hover fly  whose abdomen is smeared yellow with its pollen.

I believe that’s a hover fly with his abdomen and legs smeared yellow with pollen on this native Sand Coreopsis right in the center of the driveway at Bear Creek.

In the park and in the circle is a happy yellow flower called Golden Alexanders (Zizia aurea). It does well after a burn because our part of Michigan used to be prairie. Prairie and other grasslands across North America have burned regularly for thousands of years. Fires were either intentionally set by Native Americans or lit naturally by lightning.  This native plant is adapted to fire and loves sandy soil and sun.

 And look at the burgeoning overflow of beautiful Canada Anemone (Anemone canadensis) in the native flowerbed north of the shed!  Native plants can take a few years to really get going but once they do it is worth the effort. And clearly this was the year for these beauties.  Talk about ground cover!

While you’re admiring them, enjoy the many Hebard’s Green-legged Grasshopper nymphs (Melanoplus eurycercus) springing from leaf to leaf among the Anemone.  By August, they’ll have molted into much bigger grasshoppers.

*EDIT: thanks to reader feedback, we’ve identified this grasshopper nymph as Hebard’s Green-Legged Grasshopper instead of Green-Legged Grasshopper. Thanks for your expert critique!

Ben’s reported seeing some great birds in Bear Creek, some I have yet to see.  Cornell Ornithology Lab’s allaboutbirds.org wonderfully describes the beautiful deep blue Indigo Bunting (Passerina cyanea) as being “like a scrap of sky with wings. ”  This amazing small bird migrates at night, navigating by a single star.  The young learn their cheerful song from nearby males in their “song neighborhood” and these local songs can last for 20 years passed on by successive generations. They are tricky to photograph (as you’ll see below!) as they sing high in the treetops near woods in shrubby areas – like the northern end of the steep sloping path on the Southwest side of the park or in the center of the big loop at the northern part of the park.

Ben saw the smaller, darker Orchard Oriole (Icterus spurius) in Bear Creek.  I have a photo of the female at Bear Creek a couple of years ago but the only decent photo of the male I have was taken at our oriole feeder.  They’re here only a short time, arriving late and leaving early, sometimes as early as mid-July, for their winter home in Central America. So look for them soon before they are gone!

The male orchard oriole is smaller and more russet than the Baltimore Oriole which is more orange.
female orchard oriole
The female Orchard Oriole, like the female Baltimore Oriole,  is yellow rather than orange like its mate.

Ben also saw a bird at Bear Creek last week that I’ve never seen there – but I did hear one today at Marsh View Park.  The iris in the eye of the Red-Eyed Vireo (Vireo olivaceus) turns red when it matures so don’t be surprised when you click the link below and see a gray and white bird!  The amazing feature of these Vireos is that the male whistles his brief song incessantly from morning ’til night, sometimes repeating a song over 20,000 times in a day! Once you recognize it , you’ll know you’ve heard it in the woods for years.  So click here and then go down the page on the left to the “typical song.”

Those Green Frog tadpoles I mentioned last week are now very young frogs!  Look for them roiling the water in the pond near the playground.  They are still very small, their legs are not fully developed and some of them, as you’ll see in the photo below, still have stubs of tadpole tails that they haven’t yet absorbed into their bodies.  Like other creatures born in huge numbers, frogs serve as fast food for a lot of other species. Without lots of little frogs for nutrition, the predators that depend on them for food will be hungry. That’s one reason the declining numbers of amphibians is a concern in native habitats.

These young frogs are not fully developed yet and in fact the bottom one is still absorbing his tadpole tail into his body.

Watch for the Snapping Turtle too.  At the playground pond last Sunday, we spotted him  as a large oval patch of Duckweed moving steadily just under the surface of the water.  I imagine that he was using some young frogs as a quick snack.  Here’s a photo of one last year basking after a trip through the duckweed.

A sleepy little Gray Tree Frog  (Hyla versicolor), strictly nocturnal,  snoozed Sunday on one of the platform supports. Once grown it will generally stay high in the trees except when it comes down to breed. I imagine that’s why its skin looks so much like tree bark – good camouflage!

And what about those damsels in no distress?  Well I was referring, of course, to damselflies, those slim, elegant cousins of the dragonflies in the order Odonata.  Sunday this one flashed like neon blue morse code as it rested with its wings folded near the playground pond.  I’m guessing that it’s a Marsh Bluet ((Enallagma ebrium)) but again, don’t quote me.  Bluets are a big group of dragonflies and they all have only minor differences.

This damselfly, perhaps a Marsh Bluet, shines neon blue in the sunlight.

One of the dragonflies at the playground pond is almost comic in appearance!  I swear it has a kind of Mickey Mouse face!  Its precise but unimaginative name is the Dot-tailed Whiteface (Leucorrhinia intacta)and you can’t miss them! They’ll even accompany you down the boardwalk.

QUICK REVIEW:  New sightings of  species mentioned in earlier “This Weeks”

Evidently, the Green Heron is still fishing down at the Center Pond.  If you admire patience, speed and accuracy, this bird has it all.

Wow!  Have a look at one of the branches hanging low over the pond by the playground.  I hobbled over there with my walker last week and we spotted  the long narrow tube of an Baltimore Oriole nest among the branches.  Watch quietly and you’ll see the orange tail feathers of the female oriole as she goes head down into that tube to feed her nestlings.  She and the more colorful male foray out repeatedly gathering food, too and it’s such a close viewing spot, easily accessible for children.  Here’s a quick reminder of the nest shape, though the one at the playground pond is more hidden in the leaves.  (When I replace the camera I dunked in the marsh, I’ll try for a photo of the current one.)

A nest much like this one but hidden in leaves hanging over the playground pond contains Baltimore Oriole nestlings – with their mama head down feeding them.

And last week I featured the male Common Whitetail Dragonfly (Plathemis lydia).  Here’s a female Whitetail  who has settled on the rocks at the east end of the driveway circle.  She’s been there twice in the last week.  She lacks his bluish-white tail but has a lovely pattern down the edge of her rich brown abdomen.

Coming Attractions:

Bee balm/Wild Bergamot (Monarda fistulosa) will be blooming shortly in the native bed south of the shed, the circle in the driveway and out behind the center pond.  Only the leaves are out now but when they bloom, their lavender flowers will look a little like a frizzy hair dayBelieved to have medicinal properties (hence the name), native bee balm is indeed a balm to bees and butterflies who feed on it.

Native Bee Balm/Wild Bergamot is a good source of food for bees and butterflies.

The leaves of our native Common Milkweed (Asclepias syriaca) (which unfortunately is not as common as it needs to be) are sprouting everywhere in the park, including the driveway circle.    Before long, the leaves sprouting now will create fun landscapes like this:

milkweed bud tapestry
Milkweed leaves are sprouting around the park so their pompom-like flower balls should be showing in a few weeks.

One reason the number of Monarch Butterflies (Danaus plexippus) is dangerously low is that we don’t have enough Common Milkweed in many places.  Unfortunately, some nurseries are selling a non-native variety which can’t act as a host plant for the Monarch’s caterpillars.  And as meadows become lawns, more of our native Milkweed disappears.  We’ll explore a bit more about milkweed later in the season.

Summer is blooming: Birds feed their young, wildflowers unfold, dragonflies and damselflies dart above the ponds.  I hope you’ll find time this week to explore and relax in Bear Creek Nature Park.
