Migration Mysteries is an excellent scholarly release aimed at a wide readership within the citizen science community and beyond. Rappole creates a skillful presentation of the different facets of bird migration, combining it intelligently with personal annotations of his own research contributions and enriching it with some stunning answers derived from most recent bird behavior studies.”— Karl-L Schuchmann, Zoological Research Museum Alexander Koenig“In his insightful and thought-provoking new book, ecologist John Rappole explains that birds migrate in order to locate seasonally abundant food resources, not, as commonly assumed, because of seasonally unfavorable weather. This theory shows that most familiar migrant species evolved from resident tropical species.”—Bruce M. Beehler, author of Birds of Maryland, Delaware, and the District of Columbia“John Rappole distills a life of study and contemplation of the tantalizing and challenging phenomenon of bird migration into wonderfully accessible prose. This is a once-in-a-generation, highly readable, and insightful overview of the topic. A landmark volume for scholar and amateur alike.”—Thomas E. Lovejoy, coauthor of Ever Green: Saving Big Forests to Save the Planet
