This attractively illustrated book reviews the effects of agricultural development on bird populations in Britain. Examining modern farmland as a bird habitat, it explains the changes, both in habitat structure and in available resources, that have occurred as a result of mechanisation and use of agrochemicals. Farmland bird communities are described, and their composition related to farm structure and land use. Based extensively on empirical data extracted from the British Trust for Ornithology's Common Bird Census and from nest histories recorded in the BTO'S Nest Record Scheme, the book presents an important analysis of the position of agricultural bird populations under modern farming systems. Particular examination has been made of the impact of changing methods, rotations and crops, which have been underestimated in the past. Resulting from the co-operation between a professional ornithologist and a working cereal farmer, this book provides an objective and informed view of the impact of British agriculture on bird populations.
