Capacidade de vôo de quatro espécies de Charadriiformes (Aves) capturadas em Pernambuco, Brasil

Flight range of Charadriidae and Scolopacidae trapped in Pernambuco State, Brazil

Resumo

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 of the longest primary remige). Individuals which were changing the tenth primary were not included in this measuring. Mass was taken in grarns, and flight range was calculated using the equations proposed for adult individuais. The individual with the highest flight range reached around 1831,87 km, and had been trapped and ringed in 14th April 1994, when had 61,5 g and wing measuring 12,9 cm, with intermediate plumage. The highest flight range reached by C. fuscicollis was around 1906,43 km. It had been trapped and ringed in the 3rd of May 1992, with weight of 50 g, and wing of 12,9 cm, and had reproduction plumage. The individual with the highest flight range reached 3545,77 km, had been trapped and ringed in 15th April 1994, weighted 44 g, wing measured 10 cm, and presented intermediate plumage. The specimen of C. alba which presented the highest flight range, of 82 g, wing of 13,4 cm, and had intennediate plumage.

ABSTRACT

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 of the longest primary remige). Individuals which were changing the tenth primary were not included in this measuring. Mass was taken in grarns, and flight range was calculated using the equations proposed for adult individuais. The individual with the highest flight range reached around 1831,87 km, and had been trapped and ringed in 14th April 1994, when had 61,5 g and wing measuring 12,9 cm, with intermediate plumage. The highest flight range reached by C. fuscicollis was around 1906,43 km. It had been trapped and ringed in the 3rd of May 1992, with weight of 50 g, and wing of 12,9 cm, and had reproduction plumage.
