The Blue-headed macaw (Primolius couloni) is a small to medium-sized parrot native to the western Amazon Basin in South America, particularly found in Peru, western Brazil, and northern Bolivia. It is distinguished by its blue head, contrasting with a green body, and a red tail with blue tips. These macaws prefer subtropical or tropical moist lowland forests and often inhabit riverine areas. They are known for their strong, sociable behavior, usually seen in pairs or small groups. Blue-headed macaws are considered vulnerable due to habitat loss and the pet trade, although they are less common in captivity compared to other macaw species.
