Princess parrots are sexually dimorphic by color. The male has a blue crown with blue-gray on the sides of head, and pink around the chin and throat. His body is olive-green, and the tops of his wings are bright green with a blue-violet under wing. He has orange eyes and an orange beak. His legs are gray with pink, and each foot has three black tipped toes. The female looks like the male, except her crown is a gray-mauve, her wings are a duller color green, and her tail feathers are shorter than the male's. The male has a wingspan of 161.5 mm on average, and the female has an average wingspan of 155.2 mm. Young are a duller color than their mothers until they are eight to nine months old. At this point the color differences between the males and females start to appear.
