About the Pale-rumped Swift

The pale-rumped swift (Chaetura egregia) is a species of bird in subfamily Apodinae of the swift family Apodidae. It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru. The pale-rumped swift has at times been treated as conspecific with the grey-rumped swift (C. cinereiventris). The two of them, the band-rumped swift (C. spinicaudus), and the Lesser Antillean swift (C. martinica) were at one time placed in genus Acanthylis. The pale-rumped swift is monotypic.

The pale-rumped swift is about 10.5 cm (4.1 in) long and weighs about 23 g (0.81 oz). It has a protruding head, a short square tail, and wings that bulge in the middle and somewhat hook at the end.
