North American Ducks, Geese and Swans

This book is a richly detailed photographic guide to the Ducks, Geese, and Swans of North America, including the Hawaiian Islands, Greenland, Mexico and the U. S. Territories in the Pacific Ocean. The photographs, mostly by the author, were selected to highlight plumage phases, age classes and variation and behavioral postures. Brief text describes the different categories of waterfowl and brief bullet points highlight important identification features. Range maps and population estimates are noted in the text and some details of morphology are also provided in an Appendix.
