| The northern coast of Pernambuco State, Brazil, is an wintering area for shorebirds originally from north America, especially from the east. The first flocks arrive in September, staying till April, when they molts, change plumage, and acquire enough biomass to migrate back to the northern hemisfere. In order to calculate flight range mass and length of the wing of Charadrius semipalmatus Bonaparte, 1825, Calidris fuscicollis Vieillot, 1819, C. pusilla Linnaeus, 1766 and C. alba Pallas, 1764 was recorded. Traps were carried out in Coroa do Avião (7º40' S and 34º50'W) in the northern coast of the State of Pernambuco, between May 1992 and April 1995. The length of the wing was registered with the wing spread (from the insertion of the bone till the extremity... |

| 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... |
