I nabbed this little beauty this AM. I looked in both the Audobon and Sibley guides, but the verdict is inconclusive as to the exact name. Not a Flycatcher because behavior wasn't right, that's why I think it is a warbler. Using my Audobon guide I would think Yellow-rumped, but I have other shots of yellow-rumped and the two just don't match. If you have an idea, kindly let me know. Thanks!!!
