Here's another fall warbler that we still having hanging around in the Twin Cities. This bird hit the nets a few inches from a yellow-rumped warbler. When Amber arrived to take them out, she had to separate them--they were fighting each other! I wonder if they chased each other in? I wasn't sure what this bird was, but suspected orange-crowned warbler. However, Mark and Roger were not so sure and we had to go through a couple of different field guides to figure it out...it didn't help that the bird did not match exactly any description. Even using the vent key in the Peterson warbler guide wasn't 100%. But after a series of "if this than that" we narrowed it down to Tennessee warbler. Whew.

So take heart new birders, even in hand fall warblers can be difficult to id.
