The Blue-crowned Parakeet occurs in lowland dry forests in South America. A remarkable aspect of this species is that it occupies these deciduous forests in several widely separated regions: in northern Colombia and northern Venezuela; in the interior of northeastern Brazil; and from eastern Bolivia and south central Brazil south through Paraguay to north central Argentina. The Blue-crowned Parakeet is a large Aratinga, mostly green with a light blue crown; the extent of the blue is variable geographically, and is most restricted in the subspecies of northeastern Brazil. This species often travels in flocks, and may fly long distances between roosting sites and feeding areas. Populations of Blue-crowned Parakeet are suspected to be in decline, due to ongoing habitat loss, and from losses sustained in the international parrot trade.
