Heliothryx aurita

Identification

A medium-sized tropical hummingbird. It has bright green upperparts, white underparts and a black mask. The relatively short, straight bill is black. The graduated tail is blue-black in the centre, with white outer tail feathers (i.e. typically appear blue-black from above, white from below).

Depending on subspecies, the male has a green malar or throat.
The female is similar, but with a longer tail and no green malar/throat.

Similar Species

Virtually unmistakable in range. Male of the very similar Purple-crowned Fairy has a purple crown, and females of the two species are identical, but no overlap in distribution.

Found throughout the Amazon with a disjunct population in eastern Brazil.

Taxonomy

Previously lumped with the Purple-crowned Fairy, which is found from south-eastern Mexico to south-western Ecuador.

Subspecies

There are 3 subspecies^[1]:

• H. a. auritus:

• Tropical south-eastern Colombia to Venezuela, the Guianas and northern Brazil

• H. a. phainolaemus:

• Amazonian Brazil south of the Amazon (Pará and Maranhão)

• H. a. auriculatus:

• Tropical eastern Peru, northern Bolivia, Amazonian and southern Brazil

Habitat

In or near humid lowland forest.

Behaviour

Quite active. Its flight is light and graceful.

Diet

This hummingbird hawks small insects in the air, as well as gleaning them from foliage. When feeding on nectar, it sometimes pierces a small hole at the base of large flowers, giving access to nectar that otherwise only is accessible to hummingbirds with longer bills (e.g. Scale-throated Hermit).
