Gatherings of Angels: Migrating Birds and Their Ecology
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.
