Think Like a Bird: Understanding Bird Behavior
Bird Academy’s online course will transform your bird watching by answering questions about why birds do the things they do. This course is designed to give you all the tools you need to understand why your favorite birds act the way they do, no matter where in the world you go. Ever wonder why ducks bob their heads? Small birds chase after birds much larger than themselves? Or why swallows gather beakfulls of mud? Then this course is for you!
This six-part course also provides free access to Birds of North America that has in-depth information on all 760 bird species that breed in the U.S. and Canada.
