Macaws are distinguished from other parrots by their bare facial skin, large beaks and long tail feathers. In the wild they are seen flying over the forest canopy in pairs or in flocks made up of birds flying in pairs. Their appearance is striking with their bright plumage contrasting with the dark green forest.

Males and females look alike. Immature birds look like the adults except for the dark eyes in the young birds. The iris of the eye lightens as the bird matures.

The powerful beak of the macaw is capable of cracking open thick nutshells, tearing through cages and even destroying furniture. Prospective pet owners should think carefully before purchasing macaws. They have been known to live as long as humans and require a great deal of attention an interaction. Most macaws have the habit of screeching loudly in the morning and the late afternoon, which may be bothersome to other family members and neighbors.
