Identifying ducks, geese, and swans often comes down to recognizing distinct shapes and various arrangements of dark and light colors, especially when species are bobbing up and down on a distant water body. To equip you with the tools you need to identify waterfowl in all conditions, we have packaged together three portable references—The Basics, Dabbling & Diving Ducks, and Sea Ducks & Others— in an attractive acetate bag. Developed in partnership with the Cornell Lab of Ornithology, this beautifully illustrated resource features over 75 species of ducks, geese, and swans. These 12-panel folding pocket guides are ideal for educators, learners, naturalists, and birders. A portion of the proceeds from the sale of this set supports ongoing educational activities by The Cornell Lab of Ornithology. Made in the USA.
