Flight Paths

Did you know that one of the first ways to measure bird migration was counting the silhouettes of night-migrating birds as they passed in front of the full moon? Or that British radar operators during World War II were mystified by “angels” appearing on their screens that turned out to be seabirds in flight? Or that scientists today can tell roughly where a bird spent the winter by analyzing the ratios of hydrogen, carbon, and sulfur isotopes in its feathers?

FLIGHT PATHS, my first book, will tell the incredible scientific story of how we know what we know about bird migration, tackling the methods scientists use to track this amazing natural phenomenon — from the origins of bird banding to the latest in high-throughput genetic sequencing and space-based tracking systems — chapter by chapter. Look for it from HarperCollins in spring 2023!
