Birds, by their very existence, enhance our daily lives. For many of us, it is a thrill to see the splash of a Brown Thrasher in a birdbath, or the flash of red in green woods as a tanager darts past. It is a gift of nature that such birds – which play an important role in healthy ecosystems by controlling pests, dispersing seeds, and pollinating plants – are also so beautiful and such a joy to watch. More than sixty-three million Americans are birdwatchers, injecting billions of dollars into local economies throughout the nation as they purchase birdseed, binoculars, and guidebooks and venture. | National Wildlife Federation 11100 Wildlife Center Drive Reston Virginia 20190 703-438-6000 www.nwf.org American Bird Conservancy P.O.
