At 85cm tall and about 1.5kg in weight, they are considered to be one of the world's largest parrots.
Living in flocks of up to 30 birds, this bird has a massive hinged beak and zygodactyl toes (two toes pointing forwards and two facing backwards) allowing it to grasp food and grip while climbing.
Macaws have a distinctive and extremely loud, raucous screech.
