THRAUPIDAE

The Blue-Winged Mountain Tanager is a common species and its populations appear to be stable. Its name Anisognathus derives from the Greek roots anisos = uneven and gnathos = lower jaw. Sumptuosus derives from Latin and means extravagant.

Description

It is generally bright yellow and black with blue to the wings and tail; some populations have a moss-green back.

Distribution

In Colombia it is found at the northern end of the western mountain range up to Nariño, on both slopes of the central mountain range and on the western slope of the Eastern mountain range in Santander. Also on both slopes in Cundinamarca and headwaters of the Magdalena River in Huila. This species is found from northern Venezuela to northern Bolivia.

Habitat

The Blue-Winged Mountain Tanager lives in humid mountain forests, forest edges and secondary forests.

Feeding

It feeds on fruits and insects, but mainly on fruits. Among the fruits on which it feeds, berries of the genus Miconia and catkins of Cecropia have been recorded.

Breeding

It lays eggs between May and November in different localities of the country. Its nest is in the shape of a cup and is built with grass. Many aspects of their reproductive biology are unknown.

Behavior

It forms pairs or groups between 3 and 10 individuals, which are generally actively jumping between external branches or in the terminal foliage. Also often seen in mixed flocks, especially mid-canopy. It is a very active bird and despite its size and weight it is very agile.

Taxonomy

Formerly called Anisognathus flavinucha or flavinuchus. Anisognathus somptuosus and Anisognathus notabilis were treated as conspecifics but differ markedly in voice and plumage coloration.

Conservation status

It is classified as a species of least concern
