North American Ducks, Geese and Swans - Frank Todd - Bog

This book is the result of renowned zoologist Mr. Todds life work photographing waterfowl around the world, in an attempt to obtain images of every sex, age and plumage type feasible prior to his passing in December 2016. 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 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 identifi cation features. Range maps and population estimates are noted in the text and some details of morphology are also provided in an Appendix.
