It is found in most of Brazil, and parts of Bolivia, Uruguay, Paraguay, Argentina, and Suriname.


Prefers open areas with some trees or scrubs, cerrado, caatinga (Brazilian scrubland) and urban areas.


The nest is built about 1,5m from the ground on a small tree or scrub. The external part is made of thick branches and the interior of thin roots and grass. It may have up to four broods a year, each one with up to five eggs. Other members of the family may help raising the hatchlings. Often paratisized by Shiny Cowbird.

Feeding habits

It feeds mainly on insects and fruit, serving as a distributor of seeds, as it excretes ingested seeds intact, either in its feces or by regurgitation. It occasionally feeds on the eggs of other birds, attacking the nests.


This species has a large range, with an estimated global extent of occurrence of 7,200,000 km². The global population size has not been quantified, but it is believed to be large as the species is described as ‘common’ in at least parts of its range (Stotz et al. 1996). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e., declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern.
