[cobirds] On singing American Dippers

Interesting to read Jeff's report about dippers singing on the Big Thompson river.

Later this afternoon, as we were returning to the parking lot at South Platte park, we watched the American Dipper that frequents the river under the C470 bridge.  After watching it pick at insects and an old Starbucks cup wrapper, the dipper started spontaneously singing it's beautiful song, which raised our curiosity.  According to David Sibley's Guide to Bird Life and Behavior, both sexes of Dippers sing all year long, with a peak early in breeding season. Song establishes breeding territories in the spring, and winter territories in the fall and winter.  Fun to know!
