You simply can’t miss summer youngsters sallying forth to explore the world. Frog eggs, fledglings, fawns, ducklings, floating, flying or running with tails in the air – young creatures are setting out to explore their world.  And the wildflowers!! The flowers that declare “IT’S SUMMER!” are spattering color across the meadows, under the trees and  along the damp shores of the wetlands. It’s a season for hot sun, cool shade, “bug juice” protection after a rain – and celebrating all the life just burgeoning forth all around you.

High Summer in the Meadows

Up on the highest point, overlooking the rolling old fields of Bear Creek, tall native flowers sway and nod in the summer sunlight. Native Prairie Dock (Silphium terebinthinaceum) established its giant, sandpaper-and-leather leaves (up to 1.5 feet high and 1 ft wide!) last month.

Prairie Dock thrives after fire, so this spring’s prescribed burn really encouraged this wonderful native plant. It may be that it grows tall in order to get its flowers above tall prairie grasses, like Big Bluestem (Andropogon gerardii) which is also sprouting around the park since the burn. Naked Prairie Dock stems shoot up to 10 feet in the air topped by ball-shaped buds and bright yellow flowers. All kinds of bees probe the blossoms – and occasionally hummingbirds and as well, according to the website  www.illinoiswildflowers.info (a fave site for detailed wildflower information).

Just below them, the Yellow Coneflowers (Ratibida pinnata) dance with every passing breeze. These prairie natives actually prefer dry soil and are easy to grow if you’re considering a native garden. Just give them plenty of sun!

Purple coneflower
Native yellow coneflower is blooming below and around the giant Prairie Dock up on the south hill.

Along the trails, Wild Bee Balm/Bergamot (Monarda fistulosa) also welcomes bees, of course. In fact one small bee (Monarda dufourea) specializes in pollinating this native member of the mint family.

Bee balm, Menarda
Wild Bee Balm/Bergamot is a native that attracts all kinds of bees, even one who specializes in it!

Brilliant orange Butterfly Milkweed (Asclepias tuberosa) dots the fields with its bright orange fireworks. This native, often mistaken for the western plant Indian Paintbrush , lives up to its name. Butterflies love it, Monarchs included. Mammals avoid it, so it also gets planted in native gardens.

Of course, the fields are full of summer birds and their young as well. A male Baltimore Oriole (Icterus galbula) hopped from limb to limb at the far edge of the Eastern Path, busy finding insects for his young who fluttered along behind (juvenile not pictured here.)

I caught a photo of what appears to be a Baltimore Oriole fledgling venturing out to find food on her own one rainy morning.

A male Brown-headed Cowbird (Molothrus ater)  postured in a tree, throwing his head back to impress a competitor who assiduously ignored him.

After repeatedly seeing the flashing white patch above the tail of Northern Flickers (Colaptes auratus) as they fly up from the field to the trees in Bear Creek, I finally caught one sitting in the grass near home. These elegantly colored woodpeckers most often eat on the ground, probing for ants in the soil with their long beaks and then licking them up quickly with their barbed tongues.

Flicker male in the grass
The black “mustache” means this Northern Flicker, searching for ants in the grass, is a male.

In the distance, almost any time of day, the sweet summer song of the Rose-breasted Grosbeak (Pheucticus ludovicianus ), spills from the treetops. Some compare its intricate song to a Robin singing opera! I especially love the evening version, which to my ear, seems softer than the daytime song.

Rose breasted Grosbeak male
The Rose-breasted Grosbeak sings his lovely, intricate song off and on all day, and to my ear, a mellower version at sunset.

Male House Finches also sing cheerily in small bushes and trees. Their red feathers seem particularly intense this year which Cornell Lab says is due to the pigment in their diet during their spring molt. Something certainly livened up the color of this male!

The female House Finch wears a more sedate outfit. Here’s one fluffing up her feathers in preparation for some serious preening.

Butterflies also grace the meadows as they flutter among the blossoms.  Though we associate Common Milkweed (Asclepias syriaca) with their importance to Monarchs (Danaus plexippus), this native plant  hosts myriad butterflies.  Here a male Eastern Tiger Swallowtail (Papilio glaucus) sips its nectar on a hot afternoon.

And nearby, a Great Spangled Fritillary (Speyeria cybele) did the same.  It’s wonderful how native plants provide a natural food source for so much of our native wildlife.

This fancy insect, the Red Milkweed Beetle ((Tetraopes tetrophthalmus), is munching the milkweed’s leaves.  Doesn’t it look like a cartoon bug with its  ruffled skirt and lo-o-ong, curved “horns”?

Red Milkweed Beetle (Family Cerambycidae)
The Red Milkweed Beetle is toxic from eating milkweed and its bright colors warn predators of that fact.

According to the “Bug Lady” at the University of Wisconsin-Milwaukee, “Adult RMBs…can get away with being red and black in a green world because milkweeds are toxic, and so, therefore, are RMBs, and red and black are … aposematic (warning) colors.” If insects intrigue you, as they occasionally do me, read more about this cool bug at the Bug Lady’s link. This insect evidently “purrs,” wipes its face on a leaf if it gets too much “milk” on its mouth to prevent having it glued shut (!) and has a really interesting life cycle!

On the other side of the park, native Staghorn Sumac‘s (Rhus typhina )scarlet fruits  are already shining among deep green leaves at the edge of the Western Slope.

High Summer Between the Sunny Fields and the Shade

As you stroll toward the more moist and shady areas of the park, other creatures and wildflowers greet you as you move in and out of the bright sunlight and shade. A beautiful milkweed that loves having moist “feet,” the Swamp Milkweed (Asclepias incarnata) grows among the reeds and cat-tails along the Eastern Path and across the boardwalk from the Playground Pond. Ben VanderWeide, our township Stewardship Manager, tells me that it makes a better garden plant than Common Milkweed, because this pretty plant grows in well-behaved clumps.  Here’s one about to bloom.

Swamp Milkweed
A Swamp Milkweed about to bloom. Some lovers of native wildflowers are hoping to give it the more glamorous name, “Rose Milkweed.” I vote yes!

And another beautiful native member of the  milkweed family  is also about to bloom. Spotted Joe Pye (Eutrochium maculatum) now shows its blushing green leaves and soon its pink blossoms and purple stems will be ready for close viewing at the southern entrance to Bear Creek Marsh.

Joe Pye not yet blooming
Joe Pye will soon be blooming near the deck at the southern entrance to Bear Creek Marsh.

Of course non-natives add splashes of color at the moist border between field and forest, as well. Settlers brought to their gardens many plants with “wort” in their name, believing they had medicinal value.  Here are a couple non-native “wort” plants – Common St. John’s Wort (Hypericum perforatum) on the left and Motherwort (Leonurus cardiaca) on the right. (Hover cursor for caption; click to enlarge.)

A creature that loves dappled light,  an Ebony Jewelwing damselfly (Calopteryx maculata), pauses for a moment in bright sunlight, showing the complex color of those normally very dark wings. This seems to be a female because her abdomen is not metallic blue like the male and her wings are tipped with white dots.

One morning while birding on the northern loop of the park, a Ctencuha Moth landed on Ben and posed for a few moments.  What a striking moth with dark wings set off by yellow and light blue on the thorax and head – and its iridescent blue body blazes forth when it takes flight!

High Summer in the Pond and the Marsh

Of course, really wet areas of Bear Creek  have high summer flora and fauna all their own. Hundreds of Green Frogs (Rana clamitans) emerged last week. And suddenly all you could see at the Center Pond were their bulging yellow throats as they produced what could literally be called “full-throated” frogsong. There were so many that they were chasing each other through the water in competition for mates.

Apparently, some Green Frogs are already laying eggs. In this photo, each dark dot is a frog embryo surrounded by protective, clear “jelly” in a mass which is called “frogspawn.”   Each female frog can lay from 1,000 to 7,000 eggs – but only about five become adult frogs. Frog eggs and tadpoles are a food source for many creatures – fish, birds, and dragonflies among others. About a week from now,  the tiny tadpoles will emerge.

Frog eggs w water strider
Frog eggs float in their gelatin just below the water surface at the Center Pond while  Water Striders (family Gerridae) move across the surface above.

It appears that the family of Wood Ducks (Aix sponsa) that we birders saw earlier at the Playground Pond may have moved to the Center Pond as the fledglings became juveniles. At the far west of the pond, a female carefully supervised five youngsters as they splashed and fed.

The Center Pond also had a dragonfly visitor that I hadn’t identified before.  The usual residents, like the Dot-tailed Whiteface Dragonfly (Leucorrhinia intacta), were accompanied by a pair of Blue Dashers (Pachydiplax longipennis) who took turns perching on a branch protruding from the water. This male had probably been nearby since hatching in May, when his abdomen would have been darker blue, but as this dragonfly ages,  it “develops a coating of waxy cells that lighten it,” according to my insect “guru,” the University of Wisconsin’s “Bug Lady.”

The Blue Dasher dragonfly’s dark blue abdomen gets paler as the summer wears on. Its head, though, is a lively blue/green and its thorax is beautifully striped.

Before the rains came to break the long dry spell, the Bear Creek Marsh had gone dry, leaving an unhappy young Common Snapping Turtle (Chelydra serpentina) stranded in the drying mud. It was still moving but very slowly. It looked much happier two days later after a long, overnight rain put some water back into the marsh!

One hot Sunday afternoon, my husband and I spotted an unfamiliar bird across the water near the reeds. I didn’t get a great shot; my lens just didn’t reach far enough. I’m not sure if this is sandpiper or some other shore bird, but I’m open to suggestions. [Edit:  Expert birder Ruth Glass identifies this bird as a Solitary Sandpiper (Tringa solitaria). Thank you, Ruth!]

Common Sandpiper in the Marsh?
I saw this shore bird in the distance at the marsh. Anybody have an ID suggestion? [Edit: Expert birder Ruth Glass identified this as a Solitary Sandpiper]
The marsh, too, has its high summer blooms. Sedges of various kinds sink their roots in the mud around the northern deck. I’m getting more interested in the wide variety of these ancient plants from the genus Carex. Common Bur-Reed plants are decorated with spiky spherical fruits. Aren’t they cool shapes?

Button Bush (Cephalanthus occidentalis), a native shrub  with its Sputnik-style blooms, clusters near both entrances to the marsh. Its sputnik-like blooms decorate wetlands and attract native insects all summer and its fruits feed birds throughout the autumn and winter.

Fresh new Cat-tail heads are developing in the marsh. Male flowers cluster in the spike at the top of the stem, while tiny female flowers form in the thicker section below. While the native species is a beneficial wetland plant, the non-native invasive cattails are often aggressive, especially where lots of nutrients from lawns and roads drain into wetlands.

Cat-tails
Cat-tails have male flowers in the spike at the top, female flowers in the thicker section below.

And near the marsh, another summer native, Jewelweed (Impatiens capensis), peeks out of the shade into the sunlight. The stems of this wildflower can reduce the effects of poison ivy if mashed and rubbed against the skin, according to the National Institutes of Health.  I just like how it looks! Bees and hummingbirds like the nectar inside.

Jewel weed
Jewelweed is also called Touch-me-not, because when mature, the seeds shoot out if touched.

A Perfect Time for Youngsters to Meet Youngsters

A breezy, warm afternoon is a perfect time to introduce a child you love to some of nature’s youngsters hatching, flying, swimming and leaping through Bear Creek Nature Park.  And along the way, children can sniff the flowers (no picking!), stick a finger in the frogspawn (eeww!), try to imitate birdsong, analyze the clouds – whatever suits the child’s fancy.   Nature can fill children with delight, laughter, and wonder if they’re allowed to explore like other small creatures. Hope you and your curious youngsters get acquainted with Bear Creek’s wild youngsters and both get to spread their wings and explore high summer in the park.

THIS WEEK AT BEAR CREEK: Golden Fields Full of Monarchs, a Hummer and Other Beauties and Curiosities

Open fields edged by trees have always been favorite places of mine.  And this Tuesday,in the fields on either side of the park, Monarch butterflies were everywhere!  Bear Creek may be hosting fall migrators on their way to Mexico – or we’ve just had a big hatch of  these beautiful and ecologically fragile creatures.  In fact, many butterflies, bees and darners fluttered, hummed and hovered over the swaying seas of gold in Bear Creek, while grasshoppers serenaded them beneath the tall stems.

Some speculate that humans love open fields because our ancient ancestors felt safe where they could see into the distance but escape into the trees.  I just know I’m very happy in a field full of wildflowers.

First, of course: The Monarchs and the Hummer!

After only seeing the occasional Monarch Butterfly (Danaus plexippus) this summer, on Tuesday they were floating and fluttering all over the park!  Though the Joe Pye (Eutrochium maculatum) in the Eastern Old field seems to be past its peak,  its nectar drew in a Monarch (and other butterflies below) anyway.

I considered myself lucky to get so close – but when I started down the Western Sloping Path from north to south, wow!  Monarchs surrounded me every step of the way.  I believe I saw at least a dozen there, but I’ll share just a few who were enjoying the New England Asters.

At the very bottom of the sloping path, I watched as two Monarchs approached and fed on the same plant.

Just at that special moment, I saw the second Ruby-Throated Hummingbird (Archilochus colubris) I’ve ever seen at Bear Creek – a female, hovering momentarily as she looked at me and then zoomed off toward the woods.  No photo, of course, but perhaps this silhouette of a hummer in mid-hover from a few years ago will help you visualize the one I saw this week.

Fields Full of Wildflowers and their Beautiful Visitors

Eastern Tiger Swallowtails (Papilio glaucus) fluttered quickly across the golden fields.  I just caught sight of one in the far distance on the Eastern Path on Sunday so here’s a picture from another  August, when a male landed on Spotted Knapweed, an invasive wildflower.

New England Asters (Symphyotrichum novae-angliae) increasingly complement the Goldenrods’ glow as these vivid native flowers grow tall to reach their share of the thinning sunlight.

And the Silver-spotted Skipper (Epargyreus clarus) rested beneath a blossom of the same plant.

About That Hum in the Old Fields…

Honey Bees (Apis mellifera), native Bumblebees (genus Bombus) and even Eastern Yellow Jacket Wasps (Vespula maculifrons ) hum among the flowers in the Old Fields.  Don’t worry; they’re much too busy gathering pollen, or in the case of wasps, eating nectar, to bother with us humans.

Always on the lookout for a quick munch, the big Canada Darner Dragonfly (Aeshna canadensis) zooms and dives over the blossoms below. This B-52 of insects consumes a lot of late summer bugs.

Below the Darner, a modest wet-footed flower stands among the wetland reeds in the Eastern Old Field. According to Wikipedia, Boneset (Eupatorium perfoliatum) got its name because our ancestors believed that since the leaves clasped the stem “wrapping the leaves in bandages around splints would help mend broken bones.”

Boneset
Reportedly Boneset got its name from a past belief that because the leaves clasp the stem, it would help with mending broken bones.

Down in the grass, the Red-legged Grasshoppers (Melanoplus femurrubrum) sing lustily as a backdrop to all this beauty by rubbing their rasp-like back leg against their forewing.

Yellow Jackets, like all wasps,  don’t do much pollinating because they lack the fuzzy body hair of bees.  They generally eat nectar but collect bugs for the protein they feed to their young.

What’s That Bump on the Goldenrod, Anyway?

As you’re wandering through the Old Fields, you may have noticed some strange shapes on the stalks and tips of Canada Goldenrod (Solidago canadensis).   Galls are growths on plant stems caused by insects who lay their eggs on the plants in the spring.  When the larva hatch, they eat into the plant, causing it to form a gall around them.  Inside, the larva eats until late summer when it forms a pupa which spends the winter inside that protective covering.  In spring, the adult insect emerges to restart the life cycle. Galls don’t kill the Goldenrod; they just look funny!

The ball gall is the most common goldenrod gall and is formed by  the small Goldenrod Gall Fly (Eurosta solidaginis).  With its hard surface, this gall seems like a decent place to spend the winter, doesn’t it?  During the summer, though, some wasps lay eggs in galls and their larvae hatch and make a meal of the gall fly’s.   And in the winter,  Downy Woodpeckers drill holes in galls to reach the pupae,  and Gray Squirrels chew on galls to do the same.  Obviously enough Gall Flies survive in these dwellings to start a new crop next spring, so nature stays in balance. I think this gall may have been invaded by a wasp.

Goldenrod gall2
A ball Goldenrod gall formed by the larva of a Goldenrod Gall Fly who turns into a pupa and spends the winter there – though the holes indicate that perhaps a wasp has invaded this gall and its larva may have eaten the gall fly’s.

Goldenrods also harbor the very tiny (.2″) Goldenrod Gall Midge (Rhopalomyia solidaginis) which causes a rosette gall.  Once the grub of this tiny creature hatches, the stem of the goldenrod generally stops growing but keeps producing leaves which bunch up and make a nice hiding place for a midge’s larva to grow – along with spiders and other midges who may move in.   Sometimes, as in this photo, the stem will continue to grow above the rosette gall, but it’s much more spindly.

Goldenrod gall_edited-1
A rosette gall on Canada Goldenrod created by a single tiny insect but potentially a hiding place for other midges and spiders as well.

For years I saw willows in the park that seemed to be producing pine cones at the end of their branches.  Turns out they’re Willow Pine Cone Galls, made by a tiny (about .2″) midge scientifically known as Rhabdophaga strobiloides.  The pine cone-shaped gall that its larva causes can harbor many species.  According to the University of Wisconscin-Milwaukee’s Field Station website, “Beetles, caterpillars, sawflies, cynipid wasps, midges, and the eggs of meadow grasshoppers have been found inside pine cone galls.”  They’re now on a willow on the west side of the Center Pond and can also be seen in the wetland area east of the Eastern Path.

gall
No, not a pinecone! A Willow Pine Cone gall that can harbor over 30 different species besides the larva of its original midge.

The Eastern Old Field rolls down to the Center Pond and the Western one slopes dramatically to the west.  The trails that wind across them are full of strange and beautiful creatures and the plants that feed on and live in them.  Walk quietly. Look closely.  Listen carefully.  And when nature shares a secret with you, please share it with the rest of us.

THIS WEEK AT BEAR CREEK: More Avian Adolescents, An Influx of Fierce but Fascinating Predators and Native Plants Flourishing Everywhere

Blog post and photos by Cam Mannino
Blog post and photos by Cam Mannino

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?

Cedar Waxwing nestling

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!

This juvenile Gray Catbird still has downy leggings instead of the sleek gray shape of an adult. (See link above)

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.

IMG_0460
This young Rose-Breasted Grosbeak will grow up to be a beautiful black and white male with a rosy pink bib at his throat. (See link above)

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.

Juvenile downy woodpecker1
This juvenile Downy Woodpecker hasn’t quite got the finished look of an adult and is still learning how to find food.

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!

An adult  Downy Woodpecker looks a bit less at loose ends than the juvenile..

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 BIGGEST of 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!

Lance-tipped darner
The Lance-tipped Darner is a large dragonfly and like all dragonflies, a wildly successful predator, catching 95% of its prey which, happily, includes mosquitoes!

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.

Swamp darner
Watch for this Swamp Darner who usually appears at the end of July or early August.

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.)

A White-faced Meadowhawk dragonfly stares me down with its giant eyes which can see you both when heading toward you and flying away from you!

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.

Native Yellow Coneflowers encircle the benches on the hilltop at the south end of the park.

And right across the path, another native, Black-Eyed Susans (Rudbeckia hirta) bloom in happy profusion.

black-eyed susans
Black-eyed Susans are sometimes confused with Yellow Coneflowers – but now you can compare the two plants near the hilltop benches at the southern end of the park.

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).

False Sunflowers shine gold  in the sunlight against the shade of trees near the shed.

And tall plumes of native Meadowsweet (Spiraea alba), standing in the sunlight, hum with pollinating bumblebees.

Native meadowsweet is a perfect spot for a bumblebee carrying a load of pollen.

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!

Wild Senna produces lots of blooms right next to the stem.

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.

A native shrub, Staghorn Sumac is a beautiful and benign plant.

Coming Attraction

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.

Prairie Dock towers over the other plants in the native flowerbed near the shed. Those huge, leathery leaves in front are prairie dock plants as well.

Here’s the first beginnings of a bloom out by the benches on the southern hilltop.

Prairie Dock begins to bloom at the end of its gigantic stalk, the tallest wildflower in the park.

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!
