One cannot help being struck with wonder at the vivid pink of 10,000 flamingos rising from Lake Nakuru or the glowing red gorget of a ruby-throated hummingbird feeding outside the kitchen window. How birds produce the brilliant and striking coloration of their feathers and other body parts is the focus of this first volume of Bird Coloration. It has been more than 40 years since the mechanisms of color production of birds have been reviewed and synthesized and in those 40 years new pigments have been discovered, new genetic mechanisms have been described, new theories have been...

In this companion volume to Bird Coloration: Volume 1, Mechanisms and Measurements, Geoffrey E. Hill and Kevin J. McGraw have assembled some of the world's leading experts in the function and evolution of bird coloration to contribute to a long-overdue synthesis of a burgeoning field of inquiry. In Volume 2, the authors turn from the problem of how birds see and produce color and how researchers measure it, to what is the function of the colorful displays of birds and what are the factors that shape the evolution of color signals.
