Any of about 18 species of large tropical New World parrots (subfamily Psittacinae) with very long tails and big sickle-shaped beaks.

Macaws eat fruits and nuts. They are easily tamed and often kept as pets; some learn to mimic human speech, but most only screech. A few have lived 65 years. Best known is the scarlet macaw (Ara macao), found from Mexico to Brazil, a 36-in. (90-cm) bright-red bird with blue and yellow wings, blue and red tail, and white face.

  common name of about 18 species of large colourful parrots (parrot) native to tropical America. These brightly coloured, long-tailed birds are some of the most spectacular parrots in the world. The sexes look alike, which is uncommon among vividly coloured birds. The cobalt-blue hyacinthine macaw (Anodorhynchus hyacinthinus) of Brazil, Bolivia, and Paraguay is the largest of all parrots, measuring 95–100 cm (37.5–39.5 inches) long. The scarlet macaw (Ara macao) is probably the best known of New World parrots. Its brilliant red, yellow, and blue plumage contrasts with a bare white face that may blush when the bird is excited. Flying with distinctive slow wing beats and long tails trailing, scarlet macaws are most often seen flying to and from roosting and feeding sites in pairs, family groups, or flocks. These gregarious birds can often be heard calling in flight, emitting loud metallic screeches.

 With their large sickle-shaped beaks, macaws can crack open hard-shelled seeds and nuts, dislodging the nutmeat with blunt, muscular tongues. The beak also serves as a third foot as they climb about in trees searching for seeds as well as fruits, flowers, and leaves. One species, the blue-and-yellow macaw (Ara ararauna), has been recorded eating at least 20 species of plants, including many toxic to humans. In Manu National Park in Peru, five macaw species converge by the hundreds at mineral-rich riverbanks to eat the clay there, which may help them detoxify compounds in their diet. Macaws nest in tree hollows; hyacinthine macaws sometimes nest in riverbank holes.

      Macaws are easily tamed and some can mimic sounds. Although the parrots continue to shriek noisily, gnaw, and occasionally bite with their powerful beaks, many local people keep them as pets. They are also exported, often illegally, to supply the worldwide pet trade. This practice, along with land clearing and logging, has contributed to many macaws' (as well as other parrots') increasing rarity in the wild. A few macaws have survived to 65 years in captivity. Macaws belong to the parrot family, Psittacidae.
