RESUMO

The individuais of Charadriifonnes present plumages of either young, or adults; adults in turn, present plumages of either reproduction, ar intermediate. Aiming to monitor plumages and molts, and associating them to migrations, specimens were collected on the coast of Pernambuco State, in the Coroa do Avião, Santa Cruz channel (7º40'S e 34º 50'W). Plumages of young, non-breeding adults, intermediate adults, and breeding adults were recorded amongst the specimens captured. The molt cicle of primary remiges indicates that individuals initiating molts in June and July will not return to their areas of reproduction, and that the ones who start from August to October, ending till February, will migrate in the same year to their breeding grounds. Retrix molts showed variations. Regarding adults of Calidris pusilla (Linnaeus, 1766) the cicle ended till March.
