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, and Paraguay. It barely extends into Central America, where restricted to Panama. It is an endangered species in Trinidad, has probably been extirpated from western Ecuador, 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. It is therefore listed as Least Concern by BirdLife International.

Description
It can reach 76-86 cm (29.9-33.9 inches) long and weigh 900 to 1300 g (2-3 lbs), making it one of the biggest parrots in the world. It is vivid in appearance with blue wings and tail, black chin, golden underparts and a green forehead. Its beak is jet 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 generally mates for life. It nests at the top of tree trunks and the female typically lays two eggs. The Blue-and-yellow Macaw uses its powerful beak for breaking nutshells, and also for climbing up and hanging from trees.

Aviculture
Blue-and-yellow Macaws are popular as pets partly because of their striking appearance and ability as a talking bird.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 parrot. Blue-and-yellow Macaws are known to their owners as more of a "one person" bird, and 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 cared for Blue-and-yellow Macaw will "scream" and make other loud noises, nonetheless, it is possible to make them silent. Loud vocalizations, especially "flock calls", and destructive chewing are natural parts of their behavior and should be expected in captivity.

They require a varied diet, a seed only diet will lead to health problems such as vitamin deficiency. An example of a good diet would be a quality pelleted mix, in conjunction with a mix featuring seed, nuts, and dried fruits, with fresh vegetables (greens and roots) and fruits fed regularly; furthermore, it is quite common (and appreciated by the parrot) to partake with their human owners of safe foods like pasta, bread, etc.

It is important to avoid foods with high fat content (generally) while striving to provide a wide variety of foods. There are some foods which are toxic to birds and parrots as a group. Cherry and most other Rosaceae pits and seed, avocados, chocolate, and caffeine are among the foods toxic to parrots. Chocolate and caffeine are not metabolized by birds the same way they are in humans, Sacerdotal seed contain cyanogenic glycosides and avocados contain persin which are both toxic compounds to birds. The Blue and Yellow Macaws safe food to eat is oranges, apples, Grapes, peanuts, walnuts and sunflower seeds
