About the Gray-rumped Swift

The grey-rumped swift or gray-rumped swift (Chaetura cinereiventris) is a species of bird in subfamily Apodinae of the swift family Apodidae.

C. c. sclateri Pelzeln, 1868 C. c. cinereiventris Sclater, P.L., 1862 The grey-rumped swift, pale-rumped swift (C. egregia), band-rumped swift (C. spinicaudus), and Lesser Antillean swift (C. martinica) were at one time placed in genus Acanthylis.
