Late Summer Song
Some southbound warblers continue to sing during late August. Depending on the species or individual, a warbler's song during fall migration isn't always recognizable. Most male American Redstarts I've encountered this month are singing pretty much the same song they do during spring, they're just less emphatic. Some warblers will sing familiar fragments, like Tennessee and Canada Warblers do, but others may produce jumbled or diminutive notes that are completely unrecognizable to even the best birders.
Most warblers have given up on singing altogether. But all continue to vocalize call notes that can help reveal their identity, like the unique smacking note of a Magnolia Warbler or the loud alert of a waterthrush. Sometimes these single syllables can offer enough of a clue to help make the correct identification, or at least let you know there's something worth stopping for before continuing on down a trail. Though more challenging than spring migration, fall warbler watching (and listening) can be just as enjoyable.
Yesterday Dottie Johnson and I found nine warbler species along the Pheasant Branch Conservancy creek corridor: Northern Waterthrush, Black-and-white Warbler, Tennessee Warbler, Common Yellowthroat, American Redstart, Magnolia Warbler, Chestnut-sided Warbler, Blackpoll Warbler, and Wilson's Warbler. They're on the move!
