The San Cayetano Provincial Park is located in the northwest of the province of Corrientes, Argentina, in the Oriental District of the Chaco Phytogeographic Province. For four years, we carried out an inventory of its avifauna. We registered 179 species of birds, which constitute 36% of the birds of Corrientes, and 17% of the birds of Argentina. The habitats with the highest specific richness were forests (99 species), palmar-scrub (86 species), and swamps and lagoons (47 species); 82% of the birds were residents and 17% were migrants. The reproduction of 127 species was confirmed (71% of the total). Two species considered threatened in Argentina were registered, Turquoise-fronted Parrot (Amazona aestiva) and Upland Sandpiper (Bartramia longicauda). Despite its small size, this park has great importance because it is the only one in the northwest triangle of the province, which protects a typical sample of vegetation and birds of the Humid Chaco.
