This monograph summarizes and updates information on all bird species known from San Diego County. The species accounts begin with a brief statement indicating abundance and seasonal status. They discuss habitat requirements and preferences, numerical status or population size, spatial distribution within the county, schedule of migration, timing of the breeding season, changes in status through history, and subspecies  or problems of intraspecific geographical variation. I have allotted the most space to those species breeding in San Diego County for which there are significant problems of conservation, or in understanding distribution or migration. Rare vagrants are summarized briefly. 12 photographs -  12 color plates - over 125 maps.
