Yellow-rumped caciques (Cacicus cela) are widespread across northern South America. They can be found east of the Andes Mountains throughout the Amazon Basin. Yellow-rumped caciques are more numerous in the tropics than in temperate regions although some have been spotted along the southern border of Bolivia which is considered to be the southern (more temperate) extent of their range. They inhabit all northern countries of South America and extend east throughout the upper half of Brazil. They are native to the Amazon and have not been introduced into any other regions.
