"Lend your eyes and a little of your time to help with the next survey. You could learn how to recognize common and rare birds, including sparrows, cormorants, finches, herons, and owl. Other major projects monitor watersheds or weather patterns, or you could speak to the warden at your local park or nature reserve to see of they could use your help in your next walk."
