Answer:

Macaws are king-sized members of the parrot family and have typical parrot features. Their large, strong, curved beaks are designed to crush nuts and seeds. Their strong, agile toes are used like hands to grasp things. Loud, screeching and squawking voices help make their presence known in dense rain forests. They are also famous for their bright colors, which seem bold and conspicuous to us but actually blend in well with the green leaves, red and yellow fruits, and bluish shadows of the forest homes.

Macaws are built to fly through the trees in the forest, with a streamlined body and tail shape and wings that don’t flap deeply. When they come in for a landing, they drop their tail and feet downward and use their wings like brakes to slow down before grasping a perch with their feet. Most macaws nest in holes of trees or in earthen banks and cliff sides.

Macaws are intelligent and curious birds that like to explore and keep busy. They are very aware of their surroundings, which is necessary to keep watch for predators. As social birds, they spend a lot of time interacting with their mates and their family groups. Macaws have been known to use items like tools, and they like to play with interesting objects they find. They exam the objects from different angles, moving them with their feet, testing them with their tongue, and tossing them around. Macaws are also big chewers, something they need to do to keep their beaks in good shape. They can do impressive damage to even very hardwood with their beaks. Most macaw species like to take baths, and they play in the water as they splash around.

Screaming is a natural call for macaws. They do it to make contact with one another, to define territory, and even as part of their play. Their calls can be quite earsplitting to humans! Macaws can also imitate sounds, and macaws that live with or near humans often repeat words they hear, practicing to themselves until they get it right.

One of the outstanding natural sights in Mexico and Central and South America is a large flock of colorful macaws bursting up from the forest canopy in flight. Macaws live in pairs, family groups, or flocks of 10 to 30, which helps give them protection from predators like large snakes and birds of prey. They usually wake before dawn, preening their feathers and calling to one another, perhaps communicating where they are and what they plan to do next. Then, as a group, they fly up out of the trees to journey to the day’s feeding grounds, often traveling quite a long distance to a grove of trees with ripe fruit. In fact, macaws fly as far as 15 miles (24 kilometers) each day to feed. They feast until midday, when they settle down for more preening and "chatting," then forage more in the afternoon.  Shortly before or after dusk, macaws all take wing again to return to their roosting site, where they call to each other to figure out who sits where. The sitting arrangement can change from day to day! Sometimes squabbles break out, but macaws rarely physically injure each other. Once everyone is settled, they quiet down, fluff out their feathers, and prepare to snooze through the night.

Macaws eat a variety of ripe and unripe fruits, nuts and seeds, flowers, leaves, and stems of plants, and sources of protein like insects and snails. Some species specialize in eating the hard fruits and nuts of palm trees. One trick they use for this is to forage in fields where cattle live. The cattle eat the palm nuts, which pass through their digestive system and come out the other end with the nut’s hard coating removed. This makes the nuts softer and easier for the macaws to eat! Macaws also visit riverbanks and cliffs made of clay soil, which they eat. Scientists believe the soil neutralizes any toxic chemicals the birds might eat in seeds or unripe fruits, possibly preventing stomachaches.
