Phalaenoptilus nuttallii

Well known for habit of hibernation during cold weather (see page 309). Nominate race in part sedentary and in part migratory. N populations leave breeding grounds late Sept to Nov (N birds departing earlier than S) and move S to winter throughout S parts of range from SE California and S Texas to C Mexico; S limit of wintering range poorly known. Return to breeding grounds Feb-Mar (late Apr to mid-May farther N). Race californicus also migratory in N of range and sedentary in S. Other races generally sedentary, although some populations of race adustus may undertake altitudinal movements outside breeding season. Possible vagrant recorded in Florida.
