Great Dusky Swift Cypseloides senex

  • Order: Caprimulgiformes
  • Family: Apodidae
  • Monotypic
  • Authors: Connor Rosenblatt


Conservation Status

Due to a large geographic range and an apparent stable population, the IUCN Red List conservation status of Great Dusky Swift is evaluated as Least Concern (BirdLife International 2014).

Effects of human activity on populations

Great Dusky Swift potentailly is threatened by the building of dams, as the construction of dams could flood waterfalls, interfering with the breeding and roosting locations of this species (Oliveira 2011). In the valley of the Uruguay River, the construction of four large dams on the upper portion of the river may be responsible for the extinction or severe reduction of breeding populations there (Oliveira 2011).
