This milestone book is the first comprehensive survey of the geographical distribution of West Virginia’ s many breeding birds. More than three hundred volunteer birders systematically combed the Mountain State’ s forests, wetlands, mountains, and farmlands over a six-year period to collect the data that forms its basis. Detailed range maps are provided for 171 species of birds and two hybrids. Each map is accompanied by a summary of the bird’ s breeding range, population trends from the USFWS Breeding Bird Survey, and a discussion of factors affecting the Atlas results. Acetate map overlays allow the reader to compare bird distribution with geographical and ecological features of the state.
