There are bird sides, faces, backs, and just about every position you can imagine. At the very least, you will want to have your very own laminated field copy of all the cute little warbler asses (like below), because if you’re like me, that’s usually all the migrants give you to go on.
I prefer the .PDF versions (to .JPG’s) because I can zoom in more easily when comparing species on my desktop computer’s giant flat screen.

Happy Studying and Birding!
Only a couple of more months until warbler migration…
