Shorebirds

Edición de la obra Shorebirds

"Shorebirds are among the most attractive and popular groups of birds in the world. They are of particular interest to birders because their widespread migration means that vagrants can occur virtually anywhere. Yet, until now, existing guides to these birds have been superficial and inadequate. Shorebirds: an identification guide is the first comprehensive handbook enabling birders throughout the world to identify any species in the field. It provides the information to help both the advanced observer and the careful beginner to identify not only the species, but also, where possible, the age, sex, or racial origin of the bird. A number of important identification features are described for the first time in this book, and both text and illustrations point out the essential details needed to make a positive identification of any species." -- Back cover.
