From hummingbirds to eagles, studying the diversity of birds on campus can be endlessly rewarding, and requires no more effort than stepping outside and standing still. When you are in a hurry, you may barely notice the brown flashes darting away from you, but stop and wait and soon the ubiquitous juncos, sparrows, towhees, or chickadees will return to their peaceful foraging. On a spring dawn the birdsongs can be breathtaking. Listen at any time of year and you may hear outbreaks of worried scolding - then you get to puzzle out whether they are scolding a hawk, a bobcat, or perhaps yourself!
