The Orange-bellied parrot (Neophema chrysogaster) is a species of parrot endemic to southern Australia, and one of only two 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 upperparts, yellow underparts and orange belly patch. The adult female and juvenile are duller green in colour. All birds have a blue frontal band and blue outer wing feathers.
