Blue-and-yellow Papagali

The Blue-and-yellow Macaw (Ara ararauna), also known as the Blue-and-gold Macaw, is a member of the group of large Neotropical parrots known as macaws. It breeds in forest (especially varzea, but also in open sections of Terra Firme) and woodland of tropical South America from Trinidad and Venezuela south to Brazil, Bolivia, Colombia, and Paraguay. It extends slightly into Central America, where it is restricted to Panama. It is an endangered species in Trinidad, and is on the verge of being extirpated from Paraguay, but still remains widespread and fairly common in a large part of mainland South America. There is also a breeding population in Miami-Dade




These birds can reach 76–86 cm (29.9-33.9 inches) long and weigh 900 to 1300 g (2-3 lbs). They are vivid in appearance with blue wings and tail, dark blue chin, golden under parts and a green forehead. Beaks are black, and very strong for crushing nuts. The naked face is white, turning pink in excited birds, and lined with small black feathers.
There is little variation in plumage across the range. Some birds have a more orangey or "butterscotch" underside color, particularly on the breast. This was often seen in Trinidad birds and others of the Caribbean area, and appears to be due to environmental factors. The Blue-and-yellow Macaw uses its powerful beak for breaking nutshells, and also for climbing up and hanging from trees.

Blue-and-yellow Macaws are popular as pets partly because of their striking appearance and ability as a talking bird; however, their large size makes accommodation problematic, and they require much more effort and knowledge from owners than more traditional pets such as dogs or cats. They are intelligent and social, so for someone who can provide for their needs, they make good and loving companion parrots. Blue-and-yellow Macaws bond very closely to their owners. They tend to be more aggressive during mating season, typically 6–8 weeks in the spring time.
Even the most well-tended Blue-and-yellow Macaw will "scream" and make other loud noises. Loud vocalizations, especially "flock calls", and destructive chewing are natural parts of their behavior and should be expected in captivity. Due to their large size, they require plentiful space in which to fly. According to World Parrot Trust, an enclosure for a Blue-and-yellow Macaw should not be smaller than 15 metres (50 feet) long
