Tree Snag Birds


Hey, what's that up there on the end of the snag? Can you see it?

Let's look more closely... It's a bird—a common potoo, to be specific. Potoos are similar to our North American nightjars—the whip-poor-wills and relatives—in that they are large-mouthed, nocturnal birds that fly around catching and eating large flying moths and other insects.

Part of the common potoo's survival strategy during the day, when it's resting, is to use its cryptic plumage to blend in. It perches on top of a broken tree stub or branch, and points its bill and head upward, looking for all the world like a part of the tree. Look how well this bird blends in!

We were taken to a roosting common potoo by our guide at Asa Wright Nature Centre. The bird was perched on a distant snag, inside the canopy, but we were able to digiscope it. While taking photographs and a bit of video, we saw something remarkable happen.

Here's the video I took, combined with a clip I shot a few days later. I hope you enjoy it.





I am trying to imagine being that fledgling common potoo, roosting in its mother's (presumably its mother, though it could be its father) breast feathers. It was about 90 degrees where we were standing. How hot would it be inside those feathers? I shudder to think.

Anyway, you have now been potoo'd here at Bill of the Birds—not by just one potoo, but by two!
