molting

1. the change of coat in animals at the change of season, most noticeable in animals kept outside in cold climates that stimulate a long winter coat.
2. the replacement in birds of all their feathers once each year in the autumn. Hens stop laying for 8 to 12 weeks at this time. Molting may occur at other times if there is a feed stress.

Overlapping molt and chick rearing may permit earlier onset of molting (when prey resources often are more abundant) and, following molt, earlier initiation of fall movements to wintering areas.
Molting is the natural physiological phenomenon of anorexia, broodiness, reproductive quiescence, shedding and replacement of feathers in female birds.

However, because the same type of streamer tag was used and each lobster was handled individually, the fishermen participation could not explain the difference between recapture rates for lobsters tagged in premolt and postmolt stages for a given year; hence possible tag loss at molting was suspected as the cause of the lower recapture rates (Comeau et al.
