Silent predators of the night, owls are fascinating birds that play a crucial role in controlling rodent populations and maintaining ecological balance. In this carefully researched, well-illustrated book - the first full-scale owl-watching field guide ever published - one of the foremost American authorities on owls tells how to locate and study these remarkable birds. Birders will find expert advice and information on owl-watching equipment, owl pellets and food habits, migrations and invasions, survival adaptations, conservation, and more, along with 65 photographs plus other illustrations.

For each species, the author provides a wealth of specific data: size, wingspread, flight style, habitat, food, nesting, distribution, and other pertinent information. In addition, he has included detailed descriptions of and directions to a host of owl-watching sites in 40 states and Canada. Well-written, authoritative, and brimming with easily accessible information and expert advice, Guide to Owl Watching in North America belongs in the library of any birder or nature lover interested in observing and studying these magnificent birds of prey. | The Guide to Owl Watching in North America by Donald S Heintzelman, Paperback | Indigo Chapters
