The orange-bellied parrot is a small parrot endemic to southern Australia, and one of only three species of parrot that migrate. It was described by John Latham in 1790. A small parrot around 20 cm (8 in) long, it exhibits sexual dimorphism. The adult male is distinguished by its bright grass-green upper parts, yellow underparts and orange belly patch. The adult female and juvenile are duller green in colour. All birds have a prominent two-toned blue frontal band and blue outer wing feathers.

Healesville Sanctuary, formally known as the Sir Colin MacKenzie Sanctuary, is a zoo specialising in native Australian animals. It is located at Healesville in rural Victoria, Australia, and has a history of breeding native animals. It is one of only two places to have successfully bred a platypus, the other being Sydney's Taronga Zoo. It also assists with a breeding population of the endangered helmeted honeyeater.
