New information on bird distribution in Bolivia

Recent advances in our understanding of the Bolivian avifauna have been substantial; 1,452 species are now known for the country. This manuscript presents a compilation of records made between 2005 and the present, including records for 27 species that contribute to our understanding of elevational and geographic distributions and status of birds in Bolivia. Among the most noteworthy discoveries are further records of the only recently recorded Coscoroba Swan Coscoroba coscoroba, the first record of the globally threatened Horned Curassow Pauxi unicornis in Santa Cruz for more than a decade, evidence that Scaled Dove Columbina squamata might be becoming established in the east of the country, the second record of South American Painted Snipe Nycticryphes semicollaris in Bolivia, the fifth and sixth Bolivian records of Common Tern Sterna hirundo and the third national record of Purple-throated Cotinga Porphyrolaema porphyrolaema. These findings underscore the need for sustained research and documentation of Bolivia's avifauna.
