Chestnut-eared Aracari (Pteroglossus castanotis)


Chestnut-eared Aracari (Pteroglossus castanotis) The Chestnut-eared Aracari (Pteroglossus castanotis) is an Aracari that is native to central and south-eastern South America, where this lowland species inhabits western Brazil north to eastern Colombia and south through eastern Peru, northern and eastern Bolivia and northern Argentina.

Aracaris generally roost socially throughout the year. Up to five adults and their fledged offspring sleep in the same hole with their long tails folded over their backs.

It has the widest distribution of any aracari species and is one of the most common toucan species.

Chestnut-eared Aracari Tail Feathers Breeding / Reproduction

They typically nest in trees with appropriate hollows, most of which are previously made by woodpeckers. Other hollows are the result of a branch break and ensuing rotting of the heart wood from rain over a period of time.

Both the male and female share the incubation and chick rearing duties.

Their eggs are white and elliptical shaped. The eggs are incubated for about 16 days. The newly hatched chicks are blind and naked with short bills and thick pads on their heels to protect them from the rough floor of the nest. Both parents, as well as their previous offspring and/or possibly other adults, feed the chicks.

The young fledge after about 6 weeks. The adults continue to feed them for several weeks after fledging.

In captivity, their nests are typically constructed from palm tree logs or nesting boxes..
