The red-bellied macaw (Orthopsittaca manilatus), also known as Guacamaya Manilata, is a medium-sized, mostly green South American parrot, a member of a group of large Neotropical parrots known as macaws. It is the largest of what are commonly called "mini-macaws". The belly has a large maroon patch which gives the species its name. Not to be confused with the African red-bellied parrot (Poicephalus rufiventris), a similarly named smaller parrot.
