About the Great Dusky Swift
The great dusky swift (Cypseloides senex) is a species of bird in subfamily Cypseloidinae of the swift family Apodidae. It is found in Argentina, Brazil, Paraguay, and possibly Bolivia. The great dusky swift is monotypic.
The great dusky swift is the largest member of genus Cypseloides. It is 18 cm (7.1 in) long and weighs 56 to 110 g (2.0 to 3.9 oz). The sexes have the same plumage.
