The yellow-rumped cacique is a passerine bird in the New World family Icteridae. It breeds in much of northern South America from Panama and Trinidad south to Peru, Bolivia and central Brazil. However, they have been sighted as far north as Nayarit state in Mexico.
Region

Typical Environment
Occurs from Panama and Trinidad through northern South America including Colombia, Venezuela, the Guianas, and much of the Amazon basin south to Peru, Bolivia, and central Brazil. Prefers forest edges, gallery forests, riparian zones, and secondary growth, and readily uses plantations and semi-open countryside. Often found near water and along river corridors. Common around human-altered landscapes where tall trees remain for nesting.

This colonial nester weaves long, pendulous pouch nests that often hang near active wasp nests, which may deter predators. Its striking black body with a vivid yellow rump makes it easy to spot along forest edges and rivers. It is widespread and adaptable, commonly seen in open woodland, plantations, and village outskirts.

Social Behavior
Highly colonial, forming noisy breeding colonies in tall trees where many long, woven nests hang together. Males display prominently and may be polygynous. Nests are often placed near wasp colonies, likely gaining protection from predators. Outside breeding, birds forage in loose groups and may join mixed-species flocks.

Resident
Song Description
Vocal repertoire includes liquid whistles, chatters, and harsh buzzing notes delivered in short sequences. Males often sing from exposed perches near colonies, interspersing whistles with mechanical-sounding rattles.
