RT info:eu-repo/semantics/article T1 The avifauna of Ypetĩ Nature Reserve, and its implication for the consolidation of the Atlantic Forest Corridor in Paraguay T2 La avifauna de la Reserva Natural Ypetĩ, y su implicancia para la consolidación del Corredor de Bosque Atlántico en Paraguay A1 Esquivel, Alberto A1 Tiffer Sotomayor, Ruth A1 Diaz, Alejandrino A1 Centrón, Silvia A1 Bartrina, Lucía A1 Ruíz, Rodolfo A1 Clay, Robert Paul A1 del Castillo, Hugo Fernando A1 Yanosky Farran, Ángel Alberto A2 Guyra Paraguay AB We provide information on all birds known to date at Ypetĩ Private Nature Reserve and Estancia Golondrina. We reviewed all ornithological records from 1997 to 2017, totaling 348 bird species for the area. Habitat preferences and relative abundance for each species are detailed. The avifauna of Ypetĩ is composed of 58 Atlantic Forest endemics. At least 4 species are threatened and 9 are near-threatened, including Celeus galeatus, Amazona vinacea, and Pteroglossus bailloni. Brief comments are provided on the records of each of these species. The avifauna of the reserve is fourth in terms of species richness in the Atlantic Forest domain of Paraguay, and sixth in presence of endemics to this threatened biome.
