Endemic (ecology)
Endemism is the ecological state of being unique to a defined geographic location, such as an island, nation or other defined zone, or habitat type; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, all species of lemur are endemic to the...

The adult female and juvenile are duller green in colour. All birds have a blue frontal band and blue outer wing feathers. The diet consists of seeds and berries of small coastal grasses and shrubs.

 and winters in coastal grasslands on southern mainland Australia. With a population in the wild of fewer than 35 to 50 wild birds, it is regarded as a critically endangered species. Recent alarming declines in the wild population of Orange-bellied parrots has prompted the Australian Government to decide in April 2010 that it would capture up to 20 of the remaining wild population to further improve the genetic diversity of the species' captive breeding program as an "insurance" against extinction.

Description

The Orange-bellied Parrot is a small parrot around 20 cm (8 in) long; the adult male has bright green upperparts, and yellow below with a prominent, two-toned blue frontal band, a green-blue uppertail with yellow sides, and an orange patch on its belly. The under wing-coverts and flight feathers are dark blue, with paler blue median wing-coverts. Its iris is dark brown and beak and feet greyish. The adult female is a duller green with a paler blue frontal band. The juvenile is a duller green colour.

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.

State Level

The Orange-bellied Parrot has been recorded from four states within Australia; Tasmania, Victoria, New South Wales and South Australia. Its conservation status varies from state to state within Australia. For example:
  • The Orange-bellied Parrot is listed as threatened on the Victorian Flora and Fauna Guarantee Act (1988). Under this Act, an Action Statement for the recovery and future management of this species has been prepared.

  • On the 2007 advisory list of threatened vertebrate fauna in Victoria, the Orange-bellied Parrot is listed as critically endangered.

Threats

The 2000 Action Plan for Australian Birds identifies the following potential threats to the Orange-bellied Parrot:
  • Fragmentation and degradation of over-wintering habitat
  • Competition with introduced seed-eaters
  • Abandonment of former breeding habitat due to altered fire regime and competition for hollows (with the introduced Common Starling)
  • Random events due to the small size of the population
  • Disorientation from brightly lit fishing boats (during the migrations across Bass Strait

  • Introduced predators

  • Historically was trapped for aviculture
