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

So take a wander along the trails, as goldenrod transforms the park from green to gold, and enjoy the bright beauty of summer’s last hurrah!
Like Some Human Youngsters, A Few Avian “Adolescents” Stick Close to Mom or Dad
A young Eastern Kingbird (Tyrannus tyrannus) hid in a shrub in the eastern meadow, insisting loudly about being fed. No parental response was forthcoming from the adult on a shrub some distance away. So eventually, the youngster ventured out into the field, looking about with curiosity. Seemingly satisfied with this move toward independence, the adult flew in to feed the youngster. And then they shared the bush a while until the adult flew farther off again. (Click on slideshow’s pause button for captions.)
Two groups of Mallards (Anas platyrhynchos) were escorting their young around the Center Pond. In one group, two males and a female floated along with a small juvenile. The males are now in their late summer “eclipse plumage” which makes them look very much like the females – except that the males have yellow bills, while females’ bills are orange and black. The males will change back to their glamorous, iridescent green head feathers later in the fall when Mallards choose their mates for next spring. I guess these two males on the right were sticking close to this female just in case she made an early decision!

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

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

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

While Adults Molt, Young Birds Forage on Their Own
Many bird species molt from mid-August until mid-September, including Field Sparrows, Downy Woodpeckers, House Wrens and many others. The Eastern Kingbird, featured feeding its young above, doesn’t molt until it reaches its winter territory in South America. It’s occurred to me that since birds go into hiding during the molt, perhaps their young have to be a bit more independent sooner than other birds. Just a guess. In any case, a lot of young birds are out and about, clumsily trying to forage on their own.
I saw what I think is an adult Song Sparrow (Melospiza melodia) just beginning its molt. The bird’s feathers looked oddly fluffed out and it was picking at its breast in a persistent way. It might be a male since they molt a bit earlier than females. Below, a group of young song sparrows hopped along the trail, seeing what they could find in the grass before flying up into small trees nearby. (Click on photos to enlarge; hover cursor for captions.)

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

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

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

Glorious Wildflower Color, Exuberant Vines and a Few Pretty-but-Toxic fruits in the Woods and Shady Wetlands
Though wildflowers are not generally as numerous on the shady paths of Bear Creek, you don’t want to miss them. So keep an eye out for their exotic shapes and vivid colors shining out of the greenery as you make your way, especially near wetlands. I just learned from Wikipedia that the Jack-o’lantern mushrooms (Omphalotus olearius) below are even bio-luminescent and their gills glow faintly green in the dark when they’re fresh! Hence the name, eh?
Native Wildflowers and Grasses Bask in the Sunlight of the Meadows and Native Gardens
A spray of Purple Coneflowers in one of the native gardens
In the native gardens, the center of the parking lot, and scattered across the sunny meadows, native wildflowers bloom among the Canada Goldenrod and the Queen Anne’s lace. The monarchs seem to be enjoying them. A female sipped nectar from the Purple Coneflower and a male spread his beautiful wings on the Joe-Pye. (The field marks for males are bulges in the veins on their hind wings.) Here’s a sampling:
A Quarter-sized Creature Dons a Bubble Disguise
One cloudy afternoon, my husband spotted a very small clump of bubbles, green Water Meal (Wolffia coumbiana) and Duckweed (Lemna minor) moving slowly around the water of the center pond near the dock.
A moving patch of Water Meal, Duckweed and bubbles on the Center Pond caught our eye.
At first only the yellow/green striped head of a tiny Painted Turtle (Chrysemys picta) peeked out of the bubbly mass.
The tiny head of a Painted Turtle emerged from the bubbly greenery floating in the pond.
At last, we could see this tiny creature – a turtle about the size of a quarter – who’d found a nifty disguise to wear while munching on the Water Meal and Duckweed greenery that covers the pond. I’m betting on this little one to survive to adulthood!

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

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