We went of a Ranger guided Birder hike this morning. I have been trying to figure it out on my own but am not getting any better at it. I still just flip through the book looking for a picture that matches what I think I saw. Very frustrating. He gave great hints on how to categorize and pare down the number of pics to sift through each time. Lots of time spent discussing how they fly, bill shapes, and habitat preferences and stuff like that. At the time is seemed to make things simpler. I will let you know if that holds to be true for me!
