This parrot is named after its most distinctive feature: the bright red patch of feathers on its rump. Its striking rump contrasts with the rest of the plumage, which on males is largely grass green and on females is a duller brownish-green. The underparts also differ slightly between the sexes; the male has a yellow belly shading to white under the tail, while females are yellowish-olive below (2). The more attractively coloured male may also have blue, grey and black shades in its wing feathers, a blue tinge to its forehead and lower cheeks, and a dark green tail, tipped black and edged in white. Immature red-rumped parrots are similar to females in appearance, but duller (2).
