North America boasts a great and bewildering variety of eagles, vultures, true hawks, buteonine hawks and falcons. This book illustrates all 42 diurnal raptors found in North America at rest and in flight, in male, female, adult, juvenile and sub-adult plumages, with all usual colour morphs depicted. This array of photographs is backed up by a concise text which highlights key fieldmarks, covers potential confusion species and gives other relevant information such as measurements, range and flight style.
