Cowbird

Cowbird fledgling begging for food from Eastern Phoebe, Beech Hill Preserve, Rockport, Maine, 22 June 2017.

Brown-headed Cowbird fledgling begging for food from Eastern Phoebe.

I’m embarrassed to confess I goofed here up a week or two ago when I posted a photo of an “Eastern Phoebe” fledgling. Only today—when I saw what must’ve been the same bird being fed nearby by a frantic adult phoebe—did I realize my mistake. It was a cowbird.

Brown-headed Cowbirds are of course brood parasites: rather than build nests of their own, the females lay eggs in the nests of other birds, often dumping out their egg sin the process. I remember years ago spying a tiny wood-warbler flitting frantically around for food to stuff in the maw of a much larger cowbird fledgling.

I missed the ID when I spotted a chick flutter out of a phoebe’s nest for the first time. I recall thinking it rather odd-looking, but I guess I was too wrapped up in the moment, fixated on getting photos, to notice obvious field marks.

Well, today it was quite obvious. I felt kinda sorry for the phoebe.

Bird Brains

Yellow Warbler, Beech Hill Preserve, Rockport, Maine, 02 June 2017.

Yellow Warbler.

While walking in the woods today, listening to the songs of Eastern Wood-pewees, I got to thinking about bird brains.

If you haven’t heard a pewee sing, you’re missing out. The song is wistful, pensive, slow, intermittent, and takes a good while to complete. It begins with a slurred “Pee-oh-wee”—and the pause that follows makes you think, Simple enough. Then after ten or fifteen seconds, you hear a second “Pee-oh-wee!” just like the first. Well, that’s the song, you think. That’s the sum of it. But no. Although what follows another 10 or 15 seconds later is a third call like the first two, but after the third pause, you hear: “Peee-ohh!”

This bird has a lazy, languid, four-part song that lasts a good 40 or 45 seconds.

Somehow it keeps track. Something about this bird’s brain causes it to stretch out its delivery, to hint at false assurances before revealing a final surprise.

Every creature experiences life differently. Dogs smell the world as we cannot. Bats echolocate. Octopi are astonishingly intelligent but experience a wholly different reality. And birds have magnets in their heads—or GPS devices (or somesuch) that let them geolocate with impressive precision.

But it’s the songs of birds that most fascinate me, that make me think about their brains. Many (most?) sing more than one tune—like today’s Chestnut-sided Warblers, alternately singing Type 1 and Type 2 songs. The voices of Savannah Sparrows and Black-billed Cuckoos seem so soft and subtle and tenuous but cover impressively great distances.

Birdsong. So varied and complex. I wonder if the human brain is even capable of decoding the cipher.

Coyote!

Common Yellowthroat, Beech Hill Preserve, Rockport, Maine, 25 May 2017.

Common Yellowthroat.

While slowly ascending the upper Woods Trail at Beech Hill this overcast morning, looking for birds, Jack stopped abruptly, raised his head, and stared up into the trees, ears high. I’ve learned to pay attention to such alert behavior, and I thought, “Deer?” I peered in the direction he was looking and heard the sound of something large moving over last fall’s leaves.

Then I saw it—a deer. No, not a deer, a coyote! I big one, too, bounding away.

Jack never made a peep. Nor did I.

Nor did the coyote.
