Birds of Tropical America : A Watcher's Introduction to Behavior, Breeding and Diversity

Why are tropical birds like parrots & quetzels so much more colorful than birds of temperate lands? How can a vulture soaring thousands of feet above the canopy spot a dead rodent no bigger than a mouse on the rainforest floor? What permits sparrow-sized antbirds to thrive among hordes of army ants that devour every other living thing in their path? Hilty has led birding tours to the American Tropics for over 20 years. By providing answers to the hundreds of questions asked by participants of these expeditions, he has produced a natural history of the bird life of the New World Tropics that is as practical, accurate & fascinating as the species it reveals.Hilty, Steven L. is the author of 'Birds of Tropical America : A Watcher's Introduction to Behavior, Breeding and Diversity', published 2000 under ISBN 9780788192807 and ISBN 0788192809.
