callia

Callia refers to a genus of small, colorful birds belonging to the family Thraupidae, commonly known as tanagers. These birds are primarily found in the Neotropics, inhabiting forests and woodlands across South America. The genus Callia is characterized by its vibrant plumage, with males often displaying striking combinations of red, orange, yellow, and blue, while females tend to be more subdued in color.

Species within the Callia genus are insectivorous and frugivorous, feeding on insects, fruits, and nectar. They are often seen foraging in pairs or small flocks, moving actively through the mid-story and canopy of their forest habitats. Their songs are typically varied and melodious, contributing to the rich soundscape of their environments.

The most well-known species is likely the Paradise Tanager (Tangara chilensis), which was formerly classified within the genus Callia but has since been moved to Tangara. However, other species like the Golden-chevroned Tanager (Thraupis ornata) and the Rufous-crested Tanager (Tangara ruficapilla) have historically been placed in or closely related to the Callia lineage. Taxonomists continue to refine the classification of these beautiful birds, and the exact composition of the Callia genus can vary depending on the source.
