Migration of Birds (1979)

This engaging volume offers a thorough look at why and how birds travel across continents each year. Beginning with a clear explanation of the physical adaptations that enable flight, it guides listeners through the seasonal rhythms that drive migration, from the first stirrings in spring to the massive departures of autumn. The author blends classic observations from the 1930s with modern research up to the early 1970s, keeping the narrative lively for both seasoned birdwatchers and curious newcomers.

The book then explores the tools scientists use to track these journeys—visual spotting, sound cues, banding, radio telemetry, and even radar—illustrated with vivid diagrams that bring complex methods to life. Readers will discover the major flyways across North America, the variety of migration patterns such as loops and vertical movements, and the challenges birds face from weather to geography. By the end of the first part, listeners gain a solid foundation for appreciating the marvel of avian migration and are invited to explore the deeper questions that still intrigue researchers.
