Aves, Apodidae, Cypseloides senex (Temminck, 1826): geographical distribution in the state of Rio Grande do Sul, southern Brazil

The Great Dusky Swift Cypseloides senex occurs mainly in Argentina, Bolivia and Brazil. Little is known about the status of this species in the state of Rio Grande do Sul, Brazil. To fill this gap, several ornithologists and museum collections were consulted for records. This paper presents records for nine new localities in the state of Rio Grande do Sul. Cypseloides senex occurs along the central and northeast portions of the Planalto escarpment and the upper valley of the Uruguay River
