The Long-tailed Sylph is distributed from northern Venezuela to the Andes of Colombia, Ecuador, Peru and Bolivia. See the distribution map at Natureserve.

It is found in scrubland and clearings, gardens, etc. in the pre-montane zones. It is rarely found in forest unlike Violet-tailed Sylph A. coelestis.

It is similar to Violet-tailed Sylph but has a mainly green tail rather than violet-blue and the crown is glittering green rather than blue.

In the past the Long-tailed and the Violet-tailed Sylphs have been considered as one species but their behaviour and habitats differ. There are 6 sub-species of Long-tailed Sylph and the one pictured here, A. k. emmae is most notable for its lack of a small blue or violet throat patch found in most other sub-species.

I think that photo 3 shows an immature male. The tail is rather short and there is a white patch on the lower back.
