Backyard Bird Counters Ready to Wing It.

You can help both the National Audubon Society and the Cornell Lab of Ornithology over Presidents Day Weekend 2018. That's when the Great Backyard Bird Count will alight for its annual run, and while it flutters and flaps from Friday, Feb. 16 through Monday, Feb. 19, you won't need to commit to observing each day of the four-day run.
