It inhabits humid and semi-humid forests, gallery forests, woodland edges, and wooded savannas of the Cerrado and Caatinga mosaics, as well as patches of Atlantic Forest. The species frequents secondary growth and can visit agricultural areas for seasonal fruiting resources. It typically uses the mid- to upper canopy and often remains inconspicuous when perched.

Also known as Maximilian’s Pionus, this medium-sized parrot is noted for its subtly scalloped head plumage and bright red undertail coverts. It is generally quiet for a parrot and often keeps to the mid- to upper canopy. Though adaptable, it is affected by habitat loss and trapping in parts of its range. It nests in tree cavities and often forages in small, loose flocks.

Song Description
Calls are sharp, nasal notes and wheezy screeches, especially when in flight. Perched birds give softer, conversational chirps and grating notes, often repeated at intervals.
Plumage
Overall green body with dusky, scalloped feather edges on the head and neck that create a scaly appearance; bluish tinge on throat and chest; bright red undertail coverts.
Diet
Feeds on a broad variety of fruits, seeds, and berries, including figs and palm fruits. It also takes flower buds and nectar when available and may sample cultivated crops such as maize or fruit orchards. Foraging is often seasonal, tracking fruiting trees across the landscape.
Preferred Environment
Primarily forages in the mid- to upper canopy of forest and woodland edges, occasionally descending to lower levels for ripe fruits. It frequently uses gallery forests along rivers and wooded savannas with scattered fruiting trees.
