In The Cuckoos, Robert B. Payne presents a new evolutionary history of the cuckoo family based on molecular genetics, and uses the family tree to explore the origins and diversity of their behaviour. He traces details of the cuckoos' biology to their original sources, includes descriptions of previously unpublished field observations, and reveals new comparisons of songs showing previously overlooked cuckoo species. Illustrated with specially commissioned colour plates and numerous maps, halftones, and line drawings, The Cuckoos provides the most comprehensive and up-to-date account of this family available.
