molt

the physiological shedding of the integument, usually annual, and at the beginning of the breeding season, including the shedding of the skin by reptiles, of hair by many species, and of feathers by birds; the phenomenon is gradual, has severe metabolic overtones and leaves the bird flightless and off lay for several weeks.
