| La clasificación sistemática de las aves corresponde a la SACC, South American Classification Committee (www.museum.lsu.edu/~Remsen/SACCCountryLists.htm), que pertenece a la American Ornithologists' Union (www.americanornithology.org/) Se utiliza esta clasificación sistemática y los nombres en inglés que alli se designan. Los nombres en castellano son tomados de la "Guía de identificación de aves de Argentina y Uruguay" de Tito Narovsky y Darío Yzurieta (16va edición, 2010). |
