Monitoramento de aves limícolas na Salina Diamante Branco, Galinhos, Rio Grande do Norte, Brasil

Monitoring of the shorebirds in Diamante Branco saline, Galinhos, Rio Grande do Norte, Brazil

Resumo

Monitoring of the shorebirds of the Diamanle Branco saline located at the municipality of Galinhos, in the coast of the State of Rio Grande do Norte, was initiated in 1998, with qualitative surveys, bird traps using mist net, captured and banding and field observations on the diet of some species. Parameters such as constancy were verified, specific diversity was calculated through Pearson correlation, We registered 21 species of shorebirds, as follows: Pluvialis squatarola (Linnaeus, 1758), Charadrius semipulmatus Bonaparte 1825, renaria interpres (Linnaeus, 1758), Tringaflavipes (Gmelin, 1789), T. melanoleuca (Gmelin, 1789) and Actitis macularia (Linnaeus, 1766). It was observed the reproduction of Charadrius collaris Vieillot, 1818, C. wilsonia Ord, 1814 and Himantopus himantopus (Müller, 1776), in the surroundings of the saline evaporation tanks. The observation of Calidris himantopus (Bonaparte, 1826) in the evaporation tanks comprised the first record of the species in Northeastern Brazil. It was verified that A. interpres, T. flavipes, T. melanoleuca and Calidris pusilla (Linnaeus, 1766) feed upon A rtemia franciscana (Kellog, 1996) in the first hours ofthe day in the evaporation tanks. The mean diversity comprised 2 and 3, and the results of equibility showed that the species are well distributed in the samples. A positive association was registered between Haematopus palliatus Temminck, 1820, C. collaris, C. wilsonia, and H. himantopus. These, in turn, associated inversely to A. interpres, A. macularia, C.pusilla and C. minutilla (Vieillot, 1819), which is possibly due to the fact that some species are resident, reproducing in the locality, with movements distinct from that specie wich migrate during the boreal winter. Traps, surveys, re-lraps, and recovers indicate that the Diamante Branco saline comprises na important area for the conservation of the shorebids.

ABSTRACT

Monitoring of the shorebirds of the Diamanle Branco saline located at the municipality of Galinhos, in the coast of the State of Rio Grande do Norte, was initiated in 1998, with qualitative surveys, bird traps using mist net, captured and banding and field observations on the diet of some species. Parameters such as constancy were verified, specific diversity was calculated through Pearson correlation, We registered 21 species of shorebirds, as follows: Pluvialis squatarola (Linnaeus, 1758), Charadrius semipulmatus Bonaparte 1825, renaria interpres (Linnaeus, 1758), Tringaflavipes (Gmelin, 1789), T. melanoleuca (Gmelin, 1789) and Actitis macularia (Linnaeus, 1766). It was observed the reproduction of Charadrius collaris Vieillot, 1818, C. wilsonia Ord, 1814 and Himantopus himantopus (Müller, 1776), in the surroundings of the saline evaporation tanks. The observation of Calidris himantopus (Bonaparte, 1826) in the evaporation tanks comprised the first record of the species in Northeastern Brazil. It was verified that A. interpres, T. flavipes, T. melanoleuca and Calidris pusilla (Linnaeus, 1766) feed upon A rtemia franciscana (Kellog, 1996) in the first hours ofthe day in the evaporation tanks. The mean diversity comprised 2 and 3, and the results of equibility showed that the species are well distributed in the samples. A positive association was registered between Haematopus palliatus Temminck, 1820, C. collaris, C. wilsonia, and H. himantopus. These, in turn, associated inversely to A. interpres, A. macularia, C.pusilla and C. minutilla (Vieillot, 1819), which is possibly due to the fact that some species are resident, reproducing in the locality, with movements distinct from that specie wich migrate during the boreal winter.
