The Green-winged Macaw (also called Red & Green Macaw) isn't green-winged but has a green band between the red and blue colours of its wings. It has small red feathers on its white face. It is larger than the similar Scarlet Macaw (the latter has a yellow band between red and blue on its wings and has a bare white face). The "Ruby" Macaw is a hybrid between the Green-winged and Scarlet.
