Overview

The Blue-crowned Conure ranges widely across South America, from Colombia and Venezuela south through Bolivia and into Argentina, favoring dry woodland, savanna, and scrub habitat. It is larger and more robustly built than many green conures, and the pale blue crown that gives it its name is a reliable, easily seen field mark against its otherwise uniformly green plumage.

Identifying the Feather

Body feathers are green overall, slightly paler on the underparts than the back. The crown and forehead are washed pale blue, fading into green on the nape, a marking that stands out clearly against the surrounding green plumage and pale eye-ring. The bill is notably pale horn-colored, contrasting with the darker bills of many related conures. The tail is long and pointed, green above with a reddish or maroon tinge visible on the underside in some individuals. Overall the bird is larger and heavier-bodied than similarly green conures such as the Mitred Conure, with a proportionately bigger head and bill.

Plumage & Molt

Sexes are alike in plumage, with the blue crown present in both males and females and no other reliable visual distinction between them. Juveniles show a duller, less extensive blue crown patch that becomes more defined with maturity after the first molt.

Habitat & Range

This species occupies dry woodland, savanna, palm groves, and scrubland across a broad range in South America, including parts of Colombia, Venezuela, Brazil, Bolivia, Paraguay, and Argentina. It is largely non-migratory, though flocks may shift locally with seasonal food availability.

Behavior & Field Notes

Blue-crowned Conures feed on seeds, fruit, blossoms, and cultivated grain, foraging in flocks that can include mixed groups with other parakeet species. Nests are placed in tree cavities or occasionally in termite mounds. Calls include loud, harsh screeching notes given in flight and while perched in flocks, typical of larger conure species.
