Birds of Northern South America: An Identification Guide, Volume 2

by Robin Restall (Author), Clemencia Rodner (Author), Miguel Lentino (Author)

The two companion volumes of this extensive and detailed guide make a groundbreaking contribution to bird guide literature: they not only provide detailed accounts of every known bird species in the vast region from Ecuador to French Guiana but also, for the first time, illustrate virtually every plumage variation in full color. The illustrations include adult males and females where different as well as intermediate plumages, juveniles, subspecies, morphs and other variants, and several hypothetical and unconfirmed species. In all, nearly 6,400 birds are depicted. Black-and-white drawings of significant aspects of plumage or behavior are also provided, as are color maps showing river systems, political boundaries and the confirmed distribution of all the species.
