September Finale!

"Autumn flings her fiery cloak over the sumac, beech and oak."

― Susan Lendroth


Pheasant Branch Conservancy's prairie and oak savanna.

As September draws to a close, Autumn's vivid accents are beginning to highlight the prairie and oak savanna in a dazzling display of grasses and wildflowers. We are still a few weeks away from fall's peak colors, however. Chilly morning temperatures necessitated wearing a jacket and gloves, but the huge glowing orb of hydrogen and helium rising in the east would warm things up in short time.



As the sun's rays fanned out over the plants and trees, sparrows and other songbirds perched in the open to warm themselves. It's Sparrow Season. Hooray! The unobstructed views are the perfect time to capture quality digiscoped portraits of these fine LBJs (little brown jobs). They're fairly abundant at the moment, but soon there will be hundreds more. At least, that's my hope. In addition to the emberizids pictured below, I also found Field Sparrows, White-throated Sparrows, an Eastern Towhee, and my first Dark-eyed Junco of fall.

Several warbler species will remain present at the conservancy through the first half of October, like Yellow-rumped Warblers, Orange-crowned Warblers, Common Yellowthroats, and Palm Warblers. Here's drab but dapper Palm Warbler pumping it's tail and assessing me for threat level. Its brief pause was just enough time for me to obtain a few images of it. Perhaps this particular bird will spend the night at the prairie, as winds are once again out of the southeast.

To the uninitiated, passerines (songbirds) may appear to be just different flavors of the same mold, but taxonomically-minded birders appreciate and categorize the incredible diversity found in late September's migrants. There are sparrows, warblers, nuthatches, wrens, thrushes, vireos, flycatchers, kinglets, finches, corvids, blackbirds, woodpeckers, and more. The cool air offers crisp views through binoculars and spotting scopes, rendering fine feather detail and, dare I say, even a little personality.

Where there are oak trees, there are acorns. And where there are acorns, you might happen upon the peculiar insect known as the Acorn Weevil. Their black eyes and elongated snout (rostrum) gives them a cartoonish and yet charming appearance. The rostrum has small saw-like teeth at its end, which the female weevil uses bore holes into the sides of acorns, and then draws out the contents for nutrition. But you have to be quick! The determined weevil goes on the march without stopping when moving from one acorn to the next.

I tallied 104 bird species at Pheasant Branch Conservancy during September, 23 of which were warblers. Without looking at previous Septembers in eBird, I'm not sure if my counts are average, low, or high. Sill, I can't help but feel that over the years, from season to season, I'm observing fewer overall birds. Maybe times like when I saw hundreds of Fox Sparrows take flight from atop the drumlin were just anomalies; an exceptional flock that found the conservancy that particular fall. I also remember staying after sunset to hear hundreds of White-throated Sparrows erupt into a fantastical chirping frenzy before going to roost for the night.


New England Aster

Regardless of patterns and abundance, I'm continually appreciative of Nature's gifts and I take great care in presenting them to the best of my ability. September is over, but October is the grand songbird finale at the conservancy. I will be there to see them off and wish them safe journey. Though some might overwinter, most will not be seen or heard again until April or May.
