Burrowing Parakeet

Adults measure 39–52 cm in length, with a wingspan of 23–25 cm and a long, graduated tail that can range from 21 to 26 cm. Burrowing parrots are slightly sexually dimorphic, with males being slightly larger and weighing approximately 253-340 g, while females weigh 227-304 g, making it the largest member of the group of New World parakeet species commonly known as conures. The burrowing parrot is a distinctive parrot; it has a bare, white eye ring and post-ocular patch, its head and upper back are olive-brown, and its throat and breast are grey-brown with a whitish pectoral marking, which is variable and rarely extends across the whole breast. The lower thighs and the center of the abdomen are orange-red, and it is thought that the extent and hue of the red plumage indicates the quality of the individual as a breeding partner and parent. The lower back, upper thighs, rump, vent and flanks are yellow, and the wing coverts olive green. The tail is olive green with a blue caste when viewed from above and brown from below. The burrowing parrot has a grey bill and yellow-white iris with pink legs. Immature birds look like adults but with a horn coloured upper mandible patch and a pale grey iris. While both sexes look visually similar to the human eye, the burrowing parrot is sexually dichromatic. Males tend to have significantly redder and larger abdominal red patches, and both sexes look different under UV light, with males have brighter green feathers and females having brighter blue feathers.
