Who Am I?

I've been trying to identify this bird but here it is, 11:00 at night and I still haven't figured it out. I'm hoping someone might know what it is...

I had a very busy day watching my grandson Austin and his cousin Alissa who's visiting from Nevada. I'm fairly exhausted now so I'll say goodnight. See you all tomorrow!

Update: I posted it to the Cornell Lab of Orinthology and the thoughts are that it may be a female red-winged blackbird. I did spot a male red-wing in the backyard.

More photos of the little lady are on flickr here. and here!
