| 520 | _a"The Migration of North American Birds" by Frederick Charles Lincoln is a scientific publication written in the mid-20th century. This work thoroughly examines the patterns, behaviors, and phenomena associated with the migration of birds across North America. It discusses various theories on why and how birds migrate, details about their migratory routes, and the historical context of these natural occurrences. The opening of the book sets the stage by presenting a series of thought-provoking questions regarding the seasonal disappearance and reappearance of migratory birds. It addresses the curiosity about their routes, the dangers they face during migration, and the importance of understanding these phenomena for conservation efforts. Lincoln emphasizes the long history of interest in bird migrations, referencing ancient observations, and he outlines the extensive research conducted by the Biological Survey which provides the backdrop for the book's exploration of avian migration patterns. This introduction establishes a framework for understanding the complexity and significance of bird migrations in North America. (This is an automatically generated summary.) | ||
