Migration of Birds (1950) Circular (U.S. Fish and Wildlife Service), 16. Tom Cosmas from materials made available on The Internet Archive. "Migration of Birds" by Frederick Charles Lincoln is a scientific publication written in the mid-20th century." This work serves as an informative account of the migratory behaviors of birds, particularly those in North America, delving into the complexities of their seasonal movements, environmental influences, and evolution of their migratory patterns. The author underscores the importance of understanding these phenomena for conservation efforts and sustainable management of bird populations. "The opening of this publication lays the groundwork for an exploration of bird migration by posing fundamental questions about where birds go during the fall and whether they return to their former habitats in spring." It highlights the historical significance of migratory observations dating back millennia, supported by references from ancient texts. The text emphasizes the dual role that birds play in agricultural ecosystems as both beneficial creatures and targets for hunting, thereby illustrating the need for protective measures. Ultimately, Lincoln establishes a solid foundation for the ensuing analysis of migratory habits, aiming to increase public understanding and support for the conservation of migratory species as he prepares to present detailed findings on migration patterns, routes, and the challenges birds face during this natural phenomenon.
