The postbreeding season is an important period in the annual cycle of waterfowl that has been largely neglected by researchers (Fretwell 1972,Fredrickson and Drobney 1977). Recognition of the importance of the non-breeding period has increased recently (Fretwell 1972, Frederickson and Drobney 1977, Bailey 1981, Anderson and Batt 1983). Postbreeding studies have been more common in Europe than in North America, but these studies rarely addressed several aspects of postbreeding ecology including physiological condition, molt, and the flightless period. The postbreeding ecology of female anatids is poorly understood because of the variability in molt, time-activity budgets, and body condition relative to individual differences that are related to breeding success.The recovery from stresses incurred during breeding, completion of the prealternate molt, and accumulation of metabolic reserves for fall migration are poorly understood.
