Birdsong

I love birdsong. Naturally, I suppose, being a bird listener—and a human being with ears that register most species’ vocalizations—but I’m really attuned to birdsong. No, I mean really.

Which is no doubt the reason I’m so fascinated with even slight variations on the usual themes. I still recall one spring years ago when I heard a White-throated Sparrow whose voice started with the usual “Old Sam Peabody…” and then, instead of continuing on a steady pitch, took off into the stratosphere: “…Peabody, peaBODY, PEABODY!” I also remember three times at Beech Hill when I heard completely unfamiliar songs, chased down the birds, and they were completely familiar birds whose songs had gotten somehow completely confused. (Common Yellowthroat, Black-throated Green Warbler, Eastern Towhee.) No seriously—you would not have recognized them.

Just the other day I was watching/listening to a chickadee singing “Fee-bee!” over and over when, unexpectedly, it sang a “Fee-bee!” about two full steps lower than the ones it had been singing, then, after that aberrant one, went back to its original pitch.

One thing I’ve noticed over the years is how certain wood-warbler change their tunes mid-season. Have done some research on this, and apparently the males of these species have an early song—invariably their most distinctive, familiar one—meant to attract females and a later-season song that declares territory. I’ve noticed this in Black-and-white Warblers, Yellow Warblers, and Chestnut-sided Warblers. Another thing these guys do when singing the later-season song (a.k.a., Type II song) is perch in one place to sing it. Contrast this with their flitting about like crazy when singing their early-season love songs.

Today it was a Chestnut-sided Warbler. It sat there as I took its photo, then a video, and sang a sort of rambling, warbling jumble of notes instead of its distinctive “Pleased, pleased, pleased to MEET you!” I.e., its Type II song—or, in this species’ case, its unaccented-ending (UE) song. Here’s the video.

Interesting and/or entertaining sightings today included an upside-down Red-bellied Woodpecker, three Canada Geese flying over in the fog, a random Common Grackle in the fog, a pair of silent Common Ravens in the fog, and hummingbirds flitting all about the wood-fringes where the high-bush blueberries are blooming.

Oh, and I also heard my first crickets of the year.

Cold today still, but I imagine it’ll finally warm up at some point, as the warblers sing their B-sides.
