The Red-and-green Macaw or Green-winged Macaw (Ara chloroptera) is often mistaken for the Scarlet Macaw because of its predominately red feathering. The breast of the Red-and-green Macaw is bright red, but the lower feathers of the wing are green. In addition, the Red-and-green Macaw has characteric lines under the eyes like most larger macaws, but these markings on the Red-and-green Macaw are bright red.
Interestingly enough, the Scarlet Macaw does not have these markings. Some macaw owners and experts call the Green-winged Macaw the "gentle giant", as it is larger in size than the Scarlet Macaw and Blue-and-yellow Macaw, but has a more docile nature which often makes it a more desirable pet than the other two popular breeds. It is second only in size to the Hyacinth Macaw, the largest bird of the macaw family.
Bird experts often advise those interested in obtaining a macaw as a pet to educate themselves extensively about these birds prior to obtaining one, as they require more attention than a dog or cat.
