Author and prolific blogger Melissa Mayntz recently published her new book, Migration: Exploring the Remarkable Journeys of Birds. The illustrated book is available in hardcover (linked here) or for Kindle.
The book covers a huge variety of topics related to migration, including different reasons that birds migrate, how they follow their routes, and what they do to prepare for the journey. Myths surrounding migration are also covered.
Migration also features species profiles of birds that have unusual or extreme migration, like the Arctic Tern with its epic pole-to-pole migration journey.
