They are similar in appearance to Green wing macaws, being mostly red in color with yellow and blue wings.
Macaws have huge strong grey-black bills.
This beak also serves as a hand, and is used extensively by the macaws when climbing. They are said to be able to exert about 40 pounds of pressure with their beak. The iris of the eye is yellow and the legs a dark grey. Their feet are zygodactylous, meaning that the 2 outer toes of the foot point backwards and grip in opposition to the 2 forward-pointing toes. This gives the macaw an excellent grasp of its perch or tree limb.
