Synopses & Reviews
Review
`As has been true with past volumes in this series, and as is particularly true this year for workers in the fields of conservation/population biology, energy studies, and studies of the evolution and ecology of behavior and social organization, Current Ornithology is not just `for the birds' anymore.' Bioscience, March 1991 `The volume is excellent, and the extensive literature reviews provided at the end of each chapter make this valuable for anyone initiating a research study on one of the topics discussed.' The Wilson Bulletin, June 1991 `Volume 7 is a valuable reference.' Journal of the British Ornithologists' Union, 1990
