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. - See more at: http://animals.sandiegozoo.org/animals/macaw#sthash.Av4P9acp.dpuf
