Bronzy Inca
Coeligena coeligena
The bronzy inca is about 14 cm (5.5 in) long. Males weigh about 7.3 g (0.26 oz) and females about 6.2 g (0.22 oz). Males have a long, straight, black bill, often with some yellow at the base of the mandible; the female's bill is also straight and black but somewhat longer. The species is the drabbest member of genus Coeligena, some others of which are rather dramatically plumaged. Adult males of the nominate subspecies are mostly dark bronzy brown with a maroon sheen above; the lower back is greenish. They have a white spot behind the eye. Voice: What is thought to be the bronzy inca's song is "a continuous series of single rather sweet 'tseet' notes". Its calls include single "tsee" or "tzeet" notes, usually during flight.

Collared Inca
Coeligena torquata
10–14 centimetres (3.9–5.5 in) in length, with a rather long (3–3.5 centimetres (1.2–1.4 in)), straight, black beak. 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.
