Mealy Amazons are one of the largest species of parrot in the Americas aside from the macaws. They are mostly green, but after brief inspection more colours can be seen. They have white eye rings, and a distinct colour change on the tail, the lower half being a lighter, yellower green. They also have a red feather or two in the wings, which as a whole end in grey or blue tips. Finally, they often appear as though flour, or meal, has been sprinkled over their necks and back giving them a whitish tinge, which inspired their name. Some individual birds may have a few blue or yellow feathers on the tops of their heads.
