This can be a great time to brush up on bird id skills or learn more about bird life cycles.

Great Courses (The ones Marilyn mentioned this morning)

National Geographic Guide to Birding in North America

The Scientific Wonder of Birds

Cornell Bird Academy

These are very detailed courses on a variety of birds. I have taken the Warbler course. It was very good covering key id features, behaviors and songs. They offer a free ebird course too.
