The Sapphire-vented Puffleg (Eriocnemis luciani) – also commonly referred to as Long-tailed Puffleg – is a sedentary (non-migratory) South American hummingbird that occurs naturally in the Andes of southwest Colombia (Nariño), western Ecuador, Peru and Venezuela.
It is the largest and most widely distributed of all pufflegs found along the east slope of Andes, south and east of Maranon Valley. Even though they are not reported from Peru north of Maranon, they but might occur there.
Their preferred habitat includes elfin forest, humid montane forests (particularly at forest openings), bushy and grassy paramo slopes, and along the forest edge. They are usually found at elevations from 7,800 to 13,000 ft (2,400 – 4,000 m).

May be a hybrid.Coppery-naped Puffleg (Eriocnemis [luciani] sapphiropygia) (Taczanowski, 1874)
- Range: Central to southern Peru Even though some authorities consider the Coppery-naped Puffleg (Eriocnemis [luciani] sapphiropygia) a subspecies of the Sapphire-vented Puffleg, physical differences support treatment as separate species.

The Sapphire-vented Puffleg measures 4.5 – 4.7 inches (11.5 – 12 cm) in length (including bill and tail). Its straight, black bill is about 0.8 inches (2 cm) long. It has a long, deeply forked, blue tail. It has distinctive small white eye spots.
The plumage is mostly a glossy green with purplish blue under tail feathers.
This species was named for the snow-white dense feathering around the legs known as “leg puffs” (which are not always visible). These leg puffs are unique to the pufflegs and have been described as resembling “woolly panties” or “little cotton balls” above the legs.
The female looks similar, but her plumage is generally duller and she is variably flecked with white on her under plumage.
Nesting / Breeding
The Sapphire-vented Puffleg’s breeding season likely commences in February or March.
Diet / Feeding
The Sapphire-vented Pufflegs primarily feed on nectar taken from a variety of brightly colored, scented small flowers of trees, herbs, shrubs and epiphytes.
