This handsome little sprite is a Black-throated Gray warbler, a bird normally found in the west and southwestern U.S. I've seen them in Arizona but never east of there and in fact, it only occurs in Pennsylvania a few times in any decade. This week, though, a Black-throated Gray turned up near Carlisle, PA and was seen by dozens of observers.
It was a great find and a special treat for those us lucky enough to have the chance to enjoy it.
