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

Monitoring or the s horebirds in Diamante Branco saline, Galinhos, Rio Grand e do Norte, Brazil.Monitoring of the shorebirds oflhe Diamante Branco saline located at the municipality of Galinhos, in the coast of the State ofRi o Grande do Norte, was initiated in 1998, with qualitati ve surveys, bird traps using mist net, captured and banding and field observations o n the diet of some species.Parameters such as constancy were verified, specific diversity was calculated through Pearson correlation.We regi stered 2 1 species of shorebird s, as fo ll ows: Pluvialis squatarola (Linnaeus, 1758), Charadrius semipalmatus Bonaparte 1825, Arenaria interpres (Li nnaeus, 1758), Tringaflavipes (G melin, 1789), T. melanoleuca (Gmelin , 1789) and AClitis macularia (Linnaeus, 1766).It was observed the reproduction of Charadrius collaris Vieillot, 18 18, C. wilsonia Ord, 18 14 and HimanlOpus himanlOpus (Müller, 1776), in the surroundings of lhe saline evaporation tanks .The observation of Calidris himan topus (Bonaparte, 1826) in the evaporation tanks co mprised lhe firsl record of the species in Northeastern Brazil.It was ve rified that A. inlerpres, T. .flavipes,T. me/ano/euca and Calidrü pusilla (Linnaeus, 1766) feed upon Artemia franciscana (Kellog, 1996) in the first hours ofthe day in lheevaporation tanks.The mean diversity comprised 2 and 3, and the resuJts of equibi lity showed thal the species are well dislributed in the samples.A positi ve association was registered between Haematopus palliatus Temminck, 1820, C. col/aris, C. wilsonia, and H. himanlopus .These, in turn , associated inversely to A. inlelpres, A. macularia, C. pusilla and C. mimllil/a (Vi eill ot, 18 19), which is possibly due to the fact that some species are resident, reproducing in lhe locality, with movemenls disti nct from that specie wich migrate during lhe boreal w inter.Traps , surveys, re-traps , and recovers indicale that the Diamante Branco saline comprises na important area for the conservation of the shorebids .
