Avifauna of Mburucuyá National Park (Corrientes Province, Argentina).

Abstract

A checklist of the birds of the Mburucuyá National Park, with data of species richness, relative abundance, reproduction, and presence of threatened species is given. In the studied area, 308 species were registered between 1994 and 2009, which represent 62 % of the birds recorded for the province of Corrientes. Two hundred-six species were resident, 68 migrant and 34 of uncer tain occurrence. The families with more species were Tyrannidae (48 species), Emberizidae (24 species), Accipitridae (15 species) and Icteridae (15 species). Forests and wetlands were the habitats of the higher species richness, with 144 and 109 species of birds respectively, followed by tall grasslands with 60 species. Data of reproduction of 104 species were also obtained. Eighteen species are classified as under any level of threat of extinction for Argentina: seven endangered, three are threatened, and eight are considered vulnerable; of these, nine are considered globally threatened: two endangered, three vulnerable and four almost threatened. The fact that this number of species is experiencing any level of extinction threat reinforces the importance of the Mburucuyá National Park for the conservation of the regional avifauna.
