I've been birding for about a year now, and absolutely love it. I feel like the one area I'm still pretty rusty in, however, is identifying the buteos. I'm wondering if anyone knows of a good field guide for identifying raptors, that has all their different morphs, etc. I have the book "Hawks from Every Angle", but that only gives the views in flight. Most of the time I see a hawk it is perched. Anyway, just wondering if anyone has any suggestions. Thanks.
