Range
This tanager is a resident breeder in Costa Rica, Panama, South America south to Ecuador, Bolivia and southern Brazil, and on Trinidad.
Habitat
It is mostly found high up in trees in the forest, especially on hills, in the canopy and along the edges of forests, as well as in adjacent clearings with large trees.
Reproduction
The bulky cup nest is built in a tree and the normal clutch is two brown-blotched white eggs. The female incubates the eggs for 13-14 days to hatching, with another 15-16 days before the chicks fledge. .
Feeding habits
Found It lives in pairs or small family groups, frequently associating with flocks containing other species in its family. It feeds on fruit and small insects, which it catches close to the foliage. These are social birds which eat mainly fruit, usually swallowed whole. Insects are also taken, mainly from the underside of branches.
Conservation
This species has a large range, with an estimated global Extent of Occurrence of 4,000,000 km². The global population size has not been quantified, but it is believed to be large as the species is described as ‘frequent’ 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.
