Considered the definitive raptor identification guide for North America, this essential resource for birders includes photos and text for distinguishing between hawks, falcons, eagles, and vultures in the field, paying careful attention to plumage variations in juveniles and adults.
Whether soaring or perched, diurnal birds of prey are difficult to identify. They vary in plumage, according to age, race, color morph, or even individual differences. This, along with the difficulties of field conditions - fleeting glimpses, poor light and extreme range - have combined to make correct, positive field ID the realm of the expert birder.
But now help is at hand for the average birder. Field marks do not exist that are definitive for all raptor species, despite plumage variability. Moreover, these marks can be seen quickly under most viewing conditions. In this book two of North America's most experienced raptor identification experts provide the essential guide to these field marks, as well as, showing the range of plumage variation.
Brian Wheeler and Bill Clark have been observing, studying, and photographing raptors for many years and have taught thousands of birds to improve their ID skills through book and magazine publications, lectures, and field seminars. Here are 377 color photographs; each is stunning and each has an explanatory caption.
