Well, I was waiting for a "bird person" to weigh in. I have chickadees and had gotten an ID long ago from some birders that the pic I'd taken of one was a Carolina Chickadee. So all similar chickadees I see I just assume all are Carolina Chickadees. If we have both of those in Texas, I'm gonna be confused, because looking at my book, there doesn't seem to be much difference between that one and the Black-capped Chickadee!
