Complete Waterfowl Studies: Volume 1: Dabbling and Whistling Ducks Book

I found this guide book very readible with supberb photos of each species. Lately, when I am birding, I see large flocks of ducks which all look alike to me. What I found most helpful in this guide was the brief summary of field marks for each species. I plan to carry this guide on future birding adventures. I also plan to re-read and study the species of birds that are common in my area.

I rated the book 4 stars vs. 5, because I would have appreciated range maps to quickly identify which ducks I am likely to see in my area, or at a travel destination.
