This is the first published Atlas of breeding and wintering birds in Somerset and will be a valuable resource for anyone interested in the county's birds. It covers five years of fieldwork from winter 2007 to summer 2012 and contains maps for almost 200 species.This joint SOS/BTO project ran concurrently with the national Atlas project, and uses the same data plus that from an extra year's fieldwork. The Somerset Atlas displays bird distributions in the county at a finer resolution than the national project could achieve. The species texts are complemented by sections on habitat, methodology and coverage.
