White-tipped Swift Aeronautes montivagus

White-tipped Swift is a medium sized, black and white swift of high elevations in the tepuis in northern South America, and in the Andes from Venezuela south to Bolivia and northwestern Argentina. It has sharply pointed wings, a rather large tail with a slight fork, and dark plumage contrasting with a white throat and white thighs. White-tipped Swift resembles the partly sympatric Andean Swift (Aeronautes andecolus), but has much less white below and is generally found in more humid and more forested habitats, and has a lower elevational distribution. White-tipped Swift feeds in small flocks and nests in rock crevices and old buildings.
