Many birders can tell the difference between a white-eyed and Bell's vireo, but cannot begin to describe a vireo and what distinguishes members of this family from warblers or flycatchers. The "species by species" approach makes it difficult to appreciate birds for what they are: members of well-organized groupings united by common traits. Putting the focus on families and their shared characteristics, this guide—illustrated with 150 color photographs—makes bird identification easier and more meaningful.
