This is an Eastern kingbird. I'd never seen one before until the day that I saw several of them. They're part of the flycatcher family, and there were certainly plenty of flies out that day, so no wonder. Kingbirds have this tiny red crest on top of their shiny black heads, but they almost never show the crest. I took picture after picture, hoping to catch a glimpse of red, but never got to see it.
Nonetheless, it's a striking bird, and not a tiny one, but look how delicately it perches on this thin, old, decrepit cattail.
