Diet: Their diet consists of large insects and fruit.


Nesting: Yellow-rumped Caciques are considered colonial nesters and up to 100 nests will be located in a tree. The females build the bag-shaped nests which are suspended from the end of a branch and are usually built close to a wasp nests. (The wasps may help protect the fledglings from mites which can kill the fledglings.) The female usually lays two dark-blotched pale blue or white eggs and does all the incubation and feeding of the hatchlings.

Habitat and Range:

Vocalization: The Yellow-rumped Cacique males produce songs which are a mixture of fluting notes with cackles, wheezes and in the eastern range mimicry. The colony will also produce varied calls which can be heard from a considerable distance.

Plumage/Molt: Probably molt annually.

Migration: Not migratory.
