Regional Differences

Three subspecies are named: dorsalis in the Rocky Mountains, bacatus in the Great Lakes eastward, and fasciatus from Alaska and western Canada southward into Idaho and Oregon. These subspecies differ mostly in the plumage of the back. Eastern bacatus has a very dark back with narrow pale bars that can be difficult to see at a distance, Rocky Mountain dorsalis has a back that appears almost white, and the back of northwestern fasciatus varies from dark to whitish.
