Aeronautes andecolus andecolus
|Range||Argentina, Bolivia, Chile, and Peru.|
The Andean swift (Aeronautes andecolus), is a species of swift in the Apodidae family. It is found in Argentina, Bolivia, Chile, and Peru. Its natural habitat is subtropical or tropical high-altitude shrubland.
The Andean Swift was only recently split out of the genus Apus, and into the genus Aeronautes. There are currently three described subspecies of the Andean Swift.
Its plumage is distinctive: black cap, white underparts (with black belly band in west slope populations), and a white rump.
This swift inhabits Andes and adjacent Pacific lowlands. It is more likely to be found flying over arid, montane scrubland, rather than over forested slopes.
It is an aerial insectivore, spending nearly all of its waking hours on the wing in search of food.
They breed in relatively inaccessible breeding locations on high mountain cliffs. Very little is known about the Andean Swift's breeding biology; details about its clutch size, breeding phenology and nest form have never been described.
This bird ranges widely as singles and loose flocks, sometimes feeding low with swallows, but more often higher overhead when it can be located by its distinctive, rapid-paced buzzy chatters. It flies faster than swallows with stiff wingbeats. Like all swifts, it roosts in remote sites.
