Audubon's Corkscrew Swamp Sanctuary
More an encyclopedia than a field guide, National Geographic's Complete Birds is a browsable treasure trove of facts. This comprehensive volume profiles every bird observable in the continental United States and Canada, featuring species accounts with details that include calls and songs, breeding behaviors, molting patterns, and the vast extent of their polar and neotropical migrations. The precision maps, illuminating photographs, and more than 4,000 exquisite pieces of annotated art make this the biggest and best bird book ever.
