Résumé :	During a study of granivorous birds in the Eastern Cape, South Africa, we have recorded the timing of moult in the Cape Weaver Ploceus capensis, the Spotted-backed Weaver Ploceus cucullatus, the Masked Weaver Ploceus velatus, the Red-billed Quelea Quelea quelea, and the Red Bishop Euplectes orix. Differences in the local moult schedules of these species can be related to their particular annual cycles. Comparisons with the same species in different climatic zones of South Africa, specifically the winter rainfall area of the Western Cape, and the wetter summer rainfall region of KwaZulu-Natal, provide evidence of the extent to which the timing of moult can be modified in relation to local environmental conditions.
