Books and Maps

A Birder's Guide to Washington covers the entire state and includes detailed site descriptions with good maps. There is an excellent annotated checklist showing seasonal occurrence and tips for finding specific species. This is the guide used by serious local birders.

Birds of Washington State covers the 320 species regularly found in Washington. This guide includes identification, habitat, feeding and nesting information as well as specific recommendations about where to find each species.
Great Washington State Birding Trail maps. A project of Audubon Washington and the state chapters, these maps describe regional routes and include thumbnail descriptions of sites.

Birding Washington is one of the Falcon Guide series. It covers the entire state but is less comprehensive than A Birder's Guide to Washington. Because it is shorter it may be less daunting for the casual birder. It does not have an annotated checklist. It does have limited lodging and camping information.
