Summary The autumn moult pattern of adult Purple Sandpipers Calidris maritima in Iceland is described. The duration of the moult was estimated to be c. 5½‐7 weeks (c. 40–50 days). Females generally started moult before males and moult did not appear to overlap breeding. Information from other areas is reviewed. A mechanism by which the duration of moult is shortened amongst various species is by an increase in the number of feathers growing concurrently during the moult. Likely reasons for the placing of the moult in the annual cycle of the Purple Sandpiper are discussed, and appear to be related to the exceptionally northerly wintering distribution of the species.
