Why Dippers Dip
Why does the American Dipper dip? One possibility is that the dipper's repetitive bobbing, against a background of turbulent water, helps conceal the bird's image from predators. A second theory asserts that dipping helps the bird spot prey beneath the surface of the water. But this theory about why dippers dip holds the most promise: Dipping may be a mode of visual communication between these birds in their noisy environment.
