The caciques, are Passerine Bird s in the New World Blackbird family. Members of the family are resident breeders in tropical South America and north to Mexico . All bar one of the group are in the genus '''''Cacicus'''''.

The caciques are birds associated with open woodland or denser forests. They are colonial breeders, with several long, hanging, bag-shaped nests in a tree, each suspended from the end of a branch. Some species choose a tree that also contains an active Wasp nest as a deterent to predators, and females compete for the best sites near the protection of the wasp nest. The Egg s are incubated by the female alone.

These are slim birds with long tails and predominantly black or dark brown plumage. The pointed bill is pale yellow or blue-grey, depending on species, and several caciques have blue eyes. The female is typically smaller and duller than the male.

Three black species have the dark plumage enlivened by a red rump, five have a yellow rump and in some cases yellow on the shoulders, tail or lower belly, and the three dark brown caciques show no bright colour patches.

These gregarious birds eat large Insect s and Fruit . They are very vocal, producing a wide range of songs, sometimes including mimicry.

Some species such as the Yellow-rumped Cacique have benefited from the more open habitat created by forest clearance and ranching, but the forest-dwellers have been adversely affected for the same reason.
