Despite what the descr above suggests, this is among comparatively few raptors in N. Am. whose sexes do not normally appear to be field-distinguishable. Contra info in Sibley, young birds can retain tinges of their first plumage through their first winter. Agitated perched birds (often in colder mos., usu with 2+ present) raise and lower the tail dramatically in an even motion, sometimes accompanied by a wheezy "whip-crack" call. Often among the latest raptors to leave off evening hunting and "head for the shed," departing feeding grounds about the time the first Black-crowned Night-Herons emerge from their roost.
