Okay, I guess I am stumped. And here you thought I was an expert. Seriously, can anyone help me with this. I was at first thinking warbler, but can’t find one that looks like this, except maybe a Pine Warbler.

I think you’re right, Tony. I should have done a little more research. In fact I believe it is a female Myrtle, am I right?? I’ve seen so many males, I forgot what the female looked like. Thanks for your ID.
I believe it’s a Yellow-rumped Warbler Myrtle Winter 1. Check the link below.
