Red-rumped parrots are slim, moderate-sized parrots approximately 28 cm (11 in) in length.
The male's plumage is a bright emerald-green with yellow underparts, a brick-red rump and blue highlights on the wings and upper back.
The female's plumage is less vibrant, with pale olive underparts, dull green wings and back and blue-black wingtips. The characteristic red rump is only found in the male.
