Body mass and acquisition of breeding plumage of wintering Calidris pusilla (Linnaeus) (Aves, Scolopacidae) in the coast of Pernambuco, north-eastern Brazil

Abstract: Annually, large flocks of semipalmated sandpiper Calidris pusilla (Linnaeus, 1766) winter along South America coast, between September-April. They store fats in order to moult and return to their breeding grounds. Here, was examined body masses and plumage of adults Semipalmated Sandpipers during the departure month to evaluate the relationship between body mass and plumage. Fieldwork was conducted at Coroa do Avião (7º40'S, 34º50'W), Pernambuco. Birds were trapped in mist-nets between April 1990 and 1997. The… Show more

“…Both variations are thought to occur during preparation for the energetic demands of the migratory flight. Similar results have been reported for C. pusilla overwintering in a tropical lagoon in northeastern Brazil, 11 although the body mass increase reached higher values than those reported here and occurred one month earlier (in April).…”

“…Accounts of oversummering in the shorebird literature refer almost exclusively to young birds. The sole published measure of adult incidence of which we are aware is 8% of Semipalmated Sandpipers from Brazil [ 41 ];). Based on the migration distance pattern we documented for juveniles, the high proportion more likely relates to Paracas lying on the southern edge of the species’ wintering range.…”

“…Muitas espécies de aves interrompem seus deslocamentos migratórios para descanso e restabelecimento para continuarem viajem. Durante o deslocamento as aves migrantes requerem alta demanda energética e para isso, selecionam suas áreas de "paradas" ou pontos de "descanso", de acordo com a qualidade, produtividade e risco de predação do local (Alerstan et al 2003, Fedrizzi et al 2004. Moore & Simons (1992) relatam a importância da qualidade dos habitats utilizados como ponto de descanso e alimentação para aves migratórias, especialmente aquelas que atravessam grandes barreiras geográficas durante seus deslocamentos.…”
