Ducks Unlimited Video Guide to American Waterfowl and Game Birds.

The most complete identification guide for the field. The result of over two years of effort by Ducks Unlimited, the pioneering wetlands conservation and sportsmen's organization, this first-of-its-kind videotape documents all 43 species of waterfowl and 20 wetland upland game birds. Identifications include complete descriptions, sounds and calls, still photos, film footage, and computer-generated video techniques to provide actual wing beats both above and below water in low-light conditions found in the field. Narrated by acclaimed naturalist/photographer Michael Godfrey.
