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.
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!
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.
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 femurnigrum) sat 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 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.
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.
