Synopsis

The migration of birds has forever amazed and confounded onlookers. How do birds find their way to their destinations? How do they withstand the dangers and rigors of long-distance flight? The survival of migrant birds is increasingly threatened by environmental degradation and manmade hazards; their protection is more critical than ever. Gatherings of Angels offers first-hand accounts by leading experts who convey the beauty and excitement of migration while communicating important messages about avian conservation. The book features twenty-four pages of stunning color photographs with additional black-and-white photographs throughout.Two chapters of background information on migration precede chapters that focus on different species or groups of birds and the localities essential to their survival--from the spring flights of songbirds across the Gulf of Mexico to the massing of sandhill cranes on the Platte River. The authors discuss the timing of migrant travel; the routes followed; and the concentration of birds in stop-over sites, locations that must be preserved if they are to have secure resting spots with fresh water and ample food to fuel their journey.
