Autor: R. I. G. Morrison

Publikováno v: Ibis. 118:237-246

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 appe
