The Violet-tailed Sylph is distributed on the Pacific slopes of the western Andes in Colombia and Ecuador. These photos, taken in the Tatamá National Park are close to its northern limit. There is a distribution map at Natureserve.

It is found in cloud forest and semi-open land at between 1,000 and 2,000 metres.

The male, seen here in photos 1 to 3, is very similar to Long-tailed Sylph A. kingi but has a blue rather than green tail, a more violet gorget and a bluer rump. The female (photos 4 and 5) has a blue crown, green spots on the throat, a white chest and cinnamon rufous belly.

Its call is a rapid tez-it at about one per second.
