Warblers - Peterson Field Guide
Jon Dunn and Kimball Grant
The first comprehensive field guide to North American warblers describes all 60 species in detail, from field marks and vocalizations to mating habits and preferred habitats. The 32 colour paintings use the unique Peterson Identification System to indicate what distinguishes on bird from another. 141 colour photographs show various plumages for each species, and 60 larger colour maps show species’ ranges.
