The captive population consists of around birds, with a target of birds by — Because of the decline in the wild population in recent years, an additional 21 birds from the wild population were captured in — to improve the genetic diversity of the species' captive breeding program. Taken as a whole, the captive population, an example of ex situ conservation , is termed an "insurance population" against extinction.

The orange-bellied parrot was first described by ornithologist John Latham as Psittacus chrysogaster in , from a specimen since lost that had been collected from Adventure Bay in Tasmania in March on the second voyage of James Cook or in January on his third voyage, and subsequently been in Joseph Banks' collection. The specific name was derived from the Ancient Greek words chrysos 'golden' and gaster 'belly'.

John Gould described it in as Euphema aurantia, from an adult male specimen collected in southeast Tasmania that became the lectotype. The species name was the Latin adjective for "orange". Ewing named it Nanodes gouldii, in honour of Gould, who he believed had discovered it. Italian ornithologist Tommaso Salvadori erected the new genus Neophema in , placing the orange-bellied parrot within it and giving it its current scientific name. One of six species of grass parrot in the genus Neophema, one of four classified in the subgenus Neonanodes; it is most closely related to the rock parrot, the other two species being the blue-winged and elegant parrots. No subspecies are recognised. It has previously been known as the 'orange-breasted parrot'—a name given to the orange-bellied parrot in by the Royal Australasian Ornithologists Union or RAOU now Birdlife Australia when the word 'belly' was considered inelegant.

Other names include yellow-bellied parrot, orange-bellied grass-parakeet, and trumped-up corella. The orange-bellied parrot is a small parrot around 20 cm 8 in long; the adult male has bright green upperparts, and yellow below, a green-blue uppertail with yellow sides, and an orange patch on its belly. It has a prominent, two-toned blue frontal band, with a lighter blue border both above and below the horizontal dark blue band. The under wing-coverts and flight feathers are dark blue, with paler blue median wing-coverts. Its iris and beak is dark brown while the feet are a greyish color.

The adult female is a duller green with a paler blue frontal band. The juvenile is a duller green color. The orange-bellied parrot utters soft tinkling notes, as well as a distinctive rapidly repeated chittering alarm call unlike that of other members of the genus. The alarm call is a quickly repeated tzeet. The blue-winged and elegant parrots can be mistaken for the orange-bellied parrot, however their tinkling alarm calls and lighter olive-green upperparts distinguish them.

Their blue frontal bands have only light blue border on one side. Orange-bellied parrots only breed in South West Tasmania, where they nest in eucalypts bordering on button grass moors. The entire population migrates over Bass Strait to spend the winter on the coast of south-eastern Australia. On the way, they may stop and occasionally overwinter on King Island. BirdLife International has identified the following sites as being, or having historically been, important for orange-bellied parrots:. The orange-bellied parrot is found in pairs or small flocks, and generally remain on the ground or in low foliage searching for food. Early in the breeding season, they prefer areas that were burnt 7 to 15 years previously, while by mid-breeding season, they seek out areas that are 3 to 5 years post fire.

Their most important food plants are Beaded Glasswort Sarcocornia quinqueflora and Shrubby Glasswort Tecticornia arbuscula. Other foods include the seeds of the coast fescue Austrofestuca littoralis , saltbush Atriplex cinerea , Austral seablite Suaeda australis and sea heath Frankenia pauciflora , as well as berries, such as those of Coprosma. They have also been reported eating kelp. Breeding is restricted to southwestern Tasmania, generally within 20 km 12 mi of Melaleuca. The breeding season is October to January. They nest in hollow trees—usually Smithton peppermint Eucalyptus nitida or sometimes swamp gum E.

Four to five white eggs are laid measuring 20 mm x 23 mm. This species has a very small population and is on the verge of extinction in the wild. The current wild population is estimated at under 50 individuals, with around birds in captive breeding programs. Recent modelling suggests that on current trends the species will become extinct in the wild within five years. In , its status was upgraded from endangered to critically endangered on the Commonwealth Environment Protection and Biodiversity Conservation Act Its conservation status varies from state to state within Australia.

For example:. In early , 21 new 'founders' were collected from the wild in order to improve the captive flock's genetic diversity. These birds were shared among the three core institutions with previous orange-bellied parrot breeding experience Taroona, Healesville Sanctuary and Adelaide Zoo and were paired with existing captive birds to begin spreading new genes through the captive population.

In May , media attention focussed on the 10 individuals transferred by aircraft from Tasmania to Healesville Sanctuary near Melbourne, which was described as a last-ditch effort to save the species from extinction. It is hoped that the new additions from the wild will improve the genetic diversity of the 80 birds at Healesville Sanctuary, which are all descended from three pairs. Captive populations in Hobart and Adelaide are also important to the aim of releasing captive bred birds back to the wild. In July, , it was announced that 19 of 21 pairs with founders had produced eggs and that across all three institutions, 31 fledglings had been produced from these new pairs.

Last year saw the largest flock set out on their migration north since recovery efforts began, and we hope that a corresponding record number of birds will return this season," he said. When asked how everyday Tasmanians can help in the conservation effort to save the species, Mr Jaensch highlighted a number of ways people can promote native birdlife.
