Warbler correction -- and question

My birding friend from work, Hillel, just told me that the photo I'd labelled as yellow warbler was actually more likely a prairie warbler:
(Stupid branch! -ed.) I hardly even looked at the bird when I saw it, to be honest -- I just glanced at the yellow with the streaks and thought, "yellow warbler." But the yellow warbler's streaks are more russet, not black, and Hillel also says there's a "greenish color of the upper wing and shoulder" on what can be seen of my photographed bird that make it a prairie warbler -- which just happens to be a lifebird for me! Yippee!

Boy--was I ever mistaken on the yellow warbler ID. Here's a pic from another site:

My gosh, he's totally different! What a dummy I am! This is so awesome, though -- that makes my BIGBY list 54 birds, and my total lifelist inches up to 172! Getting closer to 200; that will be a real milestone for me. My 2008 yearlist is now somewhere around 80 (I need to update, I think). What a happy mistake!

OH WAIT--I can count this prairie warbler, right? Because I mean, I knew it was a warbler, and I got a photo --- can I count him? Help!
