Book excerpt: "The 200 photographs have been carefully selected to illustrate age, seasonal, and sexual variation in all of the species found north of Mexico, including introduced species and vagrants. The text is designed to introduce the reader to the biology, identification, molts, vocalization, and distribution of the forty-six species covered. Each photograph is accompanied by a caption outlining relevant identification features, and original range maps illustrate the distributions of all the species that regularly occur north of Mexico. This is a must-have guide for field use by amateurs and professionals alike."--Jacket.
