Greetings all:  I received 3 similar emails in re: to the odd Yellow-rumped Warbler I saw on 9-28-11; all 3 suggested what I described was a hatch year (immature) female Cape May Warbler.  I had a chance to look at my video, as well as a Sibley field guide, and it was definitely a CM Warbler, a dull hatch year female.  Sibley's has a good drawing of it, and the video is conclusive.  Thanks to those who replied - that was a great lesson!
