The vasa parrots are two species of parrot, which are native to Madagascar and other islands in the western Indian Ocean. They are distinguished for their unique physical appearance.
They have extremely truncated bodies, black-grey feathers, and a pink beak. The skin of both female and male parrots however, turn yellow during breeding season.
Like every other parrot, the male has a cloaca; a prosterior opening used for intestinal, urinary, and reproductive tracts. However, unlike other parrots this cloaca can be inverted into a hemipenis that erects during mating.
