(Thomas Alfred) 1867 1933 Coward, Thomas Alfred The Migration of Birds Produced by Chris Curnow, Sue Fleming and the Online Distributed Proofreading Team at http://www.pgdp.net "The Migration of Birds" by T. A. Coward is a scientific publication written in the early 20th century. This work meticulously explores the phenomenon of bird migration, presenting various theories and factual observations gathered from the efforts of numerous ornithologists. The focus lies on understanding the intricate behaviors, patterns, and environmental influences that drive different species of birds to migrate seasonally. At the start of the book, Coward sets the stage by defining migration and explaining its significance to birds and other species. He delves into the complexities of migration, noting that while the traditional view categorizes birds as either migratory or sedentary, many species exhibit varying degrees of movement based on seasonal changes, food availability, and breeding needs. The opening chapters introduce key concepts related to the causes and conditions of migration, as well as the historical understanding of these patterns, reflecting the author's thorough research and commitment to advancing knowledge in the field of ornithology.
