American Crows, some of our most common birds have been around human communities for centuries. With depth and perception, Lawrence Kilham has now detailed the habits and behavior of these familiar, yet often unknown birds. An intimate thoughtful prose, Kilham reveals that American Crows are cooperative breeders and describes how they maintain group territories, store food while nesting, and at other times as well. Attack young or weakened mammals and make many unusual vocalizations, audible only at close range. With discussions backed by an extensive survey of international literature on crows, Kilham has made a study that appeals to professionals as well as amateur ornithologists. Joan Waltermire stunning and strikingly original illustrations reinforce the impression conveyed in the text that the American Crow and the Common Raven are remarkable birds. 10"x7" To order by phone, toll free, call 866 596 9982.
