. Under most lighting conditions Coeligena torquata torquata appears black except for a very large and distinctive white chest-patch. However in ideal lighting other features can be discerned: a shimmering metallic violet forehead patch in males, white thighs, fleshy-dusky feet, shimmering green throat in males, dull and containing some white in females, and some dark green mixed in with the black of the body. The tail of both genders is black except for white on the basal half of the outer four rectrices, and part of the underside. The female is slightly lighter green overall than the male and has a slightly smaller chest-patch

Distribution and habitat

Humid subtropical and temperate forests, including cloud forests on both slopes of the Andes from Venezuela to Bolivia between 1800 metres (5,905.5 ft) and 3000 metres (9,842.5 ft), usually above 2100 metres (6,889.8 ft) in Ecuador. It typically forages below half the height of the canopy, and can most often be found around thickets
Thicket

They may be formed by species that shed large amounts of highly viable seeds that are able to germinate in the shelter of the maternal plants.In some conditions the...

 near the forest edge.

It is fairly common throughout most of its range. No reasons for concern have been claimed.

Diet

Like other hummingbirds, the Collared Inca obtains most of its energy from nectar, which it drinks while it in turn pollinates the flower, and feeds on insects and other small insect-like arthropods as a source of protein. It seems to prefer epiphytes. It is a solitary trap-liner

, meaning that it forages alone by flying a routine route between several flowers.

Breeding

Two single females of other Coeligena species have been observed caring for two offspring each. The nests were 1 – above ground, about 7 centimetres (2.8 in) tall and wide, with an interior cup about 3 centimetres (1.2 in) deep and wide, and were composed of seed down and other materials. The eggs were completely white and measured about 1.5x1cm. The mother visited once or twice every hour, to feed the young for a period of 9–55 s.
