Surprised a bit by seeing the photo above in a nature blog? Well, on my four October visits to Gallagher Creek Park, I noticed an abundance of a new species there – young humans and their watchful adults!
Late on autumn afternoons, this modest 15 acre park is now filled with the voices of excited little humans rocking, swinging, spinning , climbing, and sliding on the colorful new playground equipment installed in July by volunteers and staff of the Parks and Recreation Commission. (Click on photos to enlarge; hover cursor for captions.)
The park’s already becoming a place for families to cross paths and get to know their neighbors in the most densely populated part of our township. And meanwhile, in the background…
Nature Goes About Its Autumnal Business
The natural areas of Gallagher Creek look a bit scruffy right now from all the construction that went on this summer to build a picnic pavilion, a restroom enclosure, expanded parking area, the playground and a paved pathway. But despite all that to-ing and fro-ing, nature survives and offers beauty and bounty when you take time to venture into the fields.
Birds in the Distance as Children Play
Birds may keep their distance when the children are playing, but as I approached the tall grass at the edge of the creek east of the busy playground, a familiar head appeared above the tall grass.
From the absence of a white crown on its head, it seemed to be a juvenile Great Blue Heron (Ardea herodias) stalking along the far side of the creek. Young Blue Herons take 3 years to develop full adult plumage, according to the Stokes Guides to Bird Behavior (Vol. 3). This youngster flew off, as I crackled through the browning stalks of goldenrod and yarrow.
But just as I arrived the next morning, when the playground was empty, a juvenile – perhaps the same one? – flew over the treetops and swooped into a tree covered in vines. I snuck slowly forward and got one shot of it standing tall before it bent its knobby knees backward, spread those magnificent wings, and took to the air once more.
While the children shouted and laughed in the afternoon sun on a different afternoon, I watched a lone European Starling (Sturnus vulgaris) high in a snag staring out over the playground nearby. It paid no attention to the happy noises below. I imagined that it was waiting for its highly social companions, since starlings gather in huge flocks at this time of year. This one had completed its fall molt complete with fresh feathers tipped in white, giving it the spotted plumage that starlings wear in fall and winter. By spring, the white tips will be worn off, returning these birds to their iridescent blue/black mating colors, and its beak will lighten and even change to bright yellow if it’s a male.
Unnoticed by the playground youngsters, a large, rippling flock (or “murmuration”) of about 75 starlings suddenly descended on the trees east of the creek. But the lone starling just kept staring into the distance. Perhaps it just needed a break from all the cackling and whistling that goes on in a starling gathering.
Over in a quiet corner of the park, near the cat-tail marsh along the road, three little migrating Palm Warblers (Setophaga palmarum) in their duller fall colors chirped contact calls at each other before heading further south. The most notable field mark for these little birds is the bright yellow feathers under their tails and a pale “eyebrow” which they have year ’round.
Seeds Flying, Rattling, Dropping and Providing Food for Wildlife
Autumn, of course, is the time when plants ripen and disperse seeds for next spring’s blooming. In doing so, they also provide important nourishment for all kinds of creatures. So while the children played, I went out to see what kinds of food nature was preparing in the background.
Seemingly unaware of the hubbub on the playground, a struggling American Goldfinch (Spinus tristis) fumbled about trying to extract seed from a Canada Goldenrod (Solidago canadensis) while it swayed wildly in a stiff breeze. I wondered if it was a juvenile who hadn’t quite mastered the skills necessary to extract seeds on a windy day.
American Pokeweed (Phytolacca americana) would delight any child at this time of year with its hot pink stem and blackish purple berries. The trick would be to keep them from trying to eat the berries, since the seeds inside are slightly toxic to humans. According to one of my favorite wildflower sites, many of our favorite song birds (Bluebirds, Cedar Waxwings and more), as well as raccoons, opposums and the gray fox, feed on pokeweed berries with no problem. Pokeweed prefers disturbed soil, which makes Gallagher Creek Park just the right spot this year! After I took this shot, I came back a few days later to find the stem broken and picked clean. Mission accomplished – food eaten and seeds dispersed.
Some seed pods are rarely seen in our township except in this park. The wispy Bladdernut shrubs (Staphylea trifolia) produce elegant lantern-like pods. The shiny brown seeds inside shake in the wind, making a sound like a baby’s rattle. Though insects feed on the blossoms, there’s little evidence I could find that the seeds provide forage for wildlife. But the trees are doing a fine job of producing more Bladdernut shrubs as the number of them along the eastern tree line seems to be increasing nicely.
The common Cat-tails (genus Typha) are seeding as well, making a nice repast for a hungry Blue Jay (Cyanocitta cristata).
The pods of Swamp Milkweed (Asclepias incarnata) are splitting open to release their silky little parachutes, each containing a seed that can sail away on the wind. Milkweed has done its job by feeding Monarch caterpillars as well as many other butterflies and insects over the summer. So its current task is to get those seeds out into the world. If the seeds succeed in sprouting, they will feed more insects next year.
More Edibles for Wildlife Wait in the Grass
Mushrooms, of course, can be edible by humans, but they are frequently a meal for squirrels and deer as well. I saw two varieties while the children romped at Gallagher Creek. A giant Puffball (genus Calvatia) had been broken in half, probably by a curious human, since it seemed to have no teeth marks in it. One appeared in the same area last year. And a stump hosted some pretty Turkey-tail Mushrooms (Trametes versicolor), whose tough, rubbery surface might not please us, but probably could please a squirrel (particularly a Red Squirrel). I see them now and again with a mushroom between their paws.
As I stepped into the deep grass, I wished I had one of those busy children in tow to enjoy the sprays of Red-legged Grasshoppers (Melanoplus femurrubrum) leaping away from my feet. It would have made them laugh as it did me. These small grasshoppers lay their eggs less than inch under the earth in the autumn, and those eggs are a food source for birds, skunks, snakes and raccoons. Nymphs and adults can also be a food source for toads, snakes and some birds, but mostly during the summer months.
Beauty Underfoot Before the Frost
Even though much of Gallagher Creek is covered in brown stalks and shriveled blossoms, a few autumn wildflowers survived right up until the first frost. East of the observation deck, near the creek, the ground is covered with unusual and fragile Bottle Gentians (Gentiana andrewsii), a native wildflower that grows in only a few places in our township. Its closed blossoms never open so they are most often fertilized by bumblebees who are big enough to force their way inside and back out again. The gentians were so plentiful this year that I had to step carefully to avoid treading on one as I explored the area.
Nearby, a late-migrating Monarch butterfly ((Danaus plexippus) paused to sip on the last purple blossoms of New England Aster (Symphyotrichum novae-angliae), a classic autumn wildflower.
Birds Everywhere on a Cold, Quiet Morning – and a Playful Young Female
On the cold morning when I saw the heron that I mentioned above, the playground was empty and quiet. The bushes and trees, though, were alive with birds busily flitting from branch to branch, or shrub to soil, in search of anything they could find to eat.
What delighted me most was a large flock of Eastern Bluebirds (Sialia sialis). They were probably gathering to move a little farther south in Michigan or to Ohio in order to reach warmer weather, though Bluebirds often return here on warm winter days and some stay all year. The males are always the flashiest and were more plentiful in this flock.
But my favorite Bluebird on that chilly morning was what I’m guessing was a juvenile female. Young Bluebirds fledge wearing spotted breasts. But according to the Stokes Guide to Bird Behavior (Vol.2), they molt into adult plumage in August and September. I began to wonder if this gray-headed female was a youngster because she seemed to be practicing the grass-handling skills that she would need next spring in building her carefully woven nest. When I first spotted her, she had the head of a grass stem in her beak with the dry stalk trailing down her back.
She made a couple of tries at moving the grass into a more suitable position.
Seemingly frustrated, she dropped the stem between her feet and stared intently at it for a minute.
At last it seemed she had figured it out. She picked it up carefully in the middle of the stalk, a much easier way to handle it.
Satisfied, she carefully set it down on the railing on which she was perched. And then left the grass stem there and flew to nearby tree.
I loved seeing this young bird fiddle with what may have been her first attempt at handling the building material she would need in the spring to create her nest.
Besides the Bluebirds, a whole assortment of other birds made the most of the quiet park that cold morning. I’m fairly sure that a tiny migrating Ruby-crowned Kinglet (Regulus calendula) was among them, but it insisted on keeping only its rear in view! So I’ve added a photo of another one I saw in a previous year so you can have a better look at it. (Use the pause button if more time is needed for captions.)
A Park Where the Young Can Learn and Play
I believe that young humans, like the young of all species, need play as a way to learn about the world. So I loved watching children on the new playground at Gallagher Creek Park. So much is being learned as youngsters cope with siblings and strangers on the slide or the rocking “dragonfly” seesaw. Muscles grow stronger. Some learn the consequences of risk-taking and others overcome their fears. It’s great.
What I’m hoping is that once the trails are mowed again next spring, parents will take their children by the hand and explore this little park that offers so much – baby muskrats in the spring, a swollen creek after rain, tree swallows diving for insects in the summer, and native wildflowers in three seasons. And yes, even little birds, that like all children, are learning how to be skillful grown-ups.
