A few weeks ago I was at the local state park again and saw, for the first time in this area, a black-and-white warbler. I wasn't able to get as close as I wanted to so here are the best shots I have:

I think its a female, according to what my bird guide shows, b/c the male has more black along the face and throat than this one has.
