Here, for the first time, molt is presented for the nonscientist. Molt is very orderly and built on only four underlying strategies: Simple Basic, Complex Basic, Simple Alternate, and Complex Alternate. This book clearly lays out these strategies, and the more than 270 photographs help make the subject accessible. Each family of birds has its own account, starting with an overview of factors such as biogeography, taxonomy, habitat, and migration. Next come the molting strategy or strategies of the family, as well as when and where the different molts occur. In-depth explanations usually follow, often broken down into one or more sections that cover the particular molts and relate them to aspects of life history and ancestry. Additional topics include case studies, groups of particular interest, and related subjects.
