Australian parakeet nearing extinction

With a population of less than 25 in the wild, the Orange-bellied Parrot (Neophema chrysogaster) is one of the rarest birds on earth, due to loss of its overwintering habitat and competition with other species.

Project progress: In 2002 the Trust supported the Orange-bellied Recovery Program with its Small Action Grants.  This helped to:

  • Employ an Extension Officer for 8 weeks
  • Expand the volunteer observer network
  • Conduct a coordinated habitat-wide survey with results to the Recovery Team
  • Monitor and report activities at Piccaninnie Ponds
  • Construct a feed table adjacent to Piccaninnie Ponds
  • Develop a supplementary feed crop and study its use by the birds during winter migration

Outcomes: A recovery team for the Orange-bellied Parrot was first established in 1980.  The wild population, which was estimated to number around 150 individuals in 2005, has since undergone a rapid decline and in early 2017 fewer than 20 birds were found at Melaleuca with no birds elsewhere. Individuals are being bred in captive breeding programs in Taroona, Tasmania, Healesville Sanctuary, Adelaide Zoo, Melbourne Zoo, Halls Gap Zoo (previously), Moonlit Sanctuary and Priam Parrot Breeding Centre. The captive population totals 325 birds.  Because of the precipitous decline in the wild population, an additional 21 birds from the wild population were captured in 2011 to provide genetic diversity in the species' captive breeding program. In early 2017 it was reported that sixteen captive birds succumbed to Pseudomonas aeruginosa infection in Hobart Wildlife Centre, while Moonlit Sanctuary was reporting good progress with eight new chicks. At Healesville Sanctuary, over 40 eggs had hatched by January 2017.

IUCN/CITES Status: Critically Endangered / Appendix I

Wild population: Less than 25, with about 325 held in captive breeding programme.

Where found: Tasmania and coastal SE mainland Australia.

History: This species is believed to breed only at Melaleuca and Birch's Inlet (historically) in south-western Tasmania, Australia (C. Tzaros and M.A. Weston in litt. 2003).  After breeding, birds migrate to the mainland, stopping at King Island.  They then overwinter at sites scattered from south-eastern South Australia to south-eastern New South Wales (C. Tzaros and M.A. Weston in litt. 2003). Annual winter counts in Victoria, South Australia and Bass Strait in the years from 1979 to 1990 varied between 67 and 122, not changing significantly. Numbers from the mainland have since declined. Population surveys in early 2010 found fewer than 50 birds at Melaleuca and none at other historical breeding areas (Sims 2010). Extinction in the wild has been predicted to take place within 3-5 years (Sims 2010). There are over 300 birds now held in captivity in three locations.

Threats:

  •     Fragmentation and degradation of overwintering habitat by grazing, agriculture and development
  •     Competition with introduced seed-eating finches affecting winter food availability
  •     Habitat loss because of a change in the fire regime
  •     Degradation of remaining saltmarsh habitat on the mainland (Tzaros and Weston in litt. 2003)
  •     The deaths of unknown causes of 40 young birds bred in captivity; possible viral disease

Ecology: Breeding areas include temperate forest and moorland plains; wintering areas are mostly saltmarsh and pastureland with freshwater sources and roosting sites.  Birds feed mainly on seeds and are seen in flocks, usually with a sentinel to warn the group of predators. In breeding areas birds roost communally in dense Melaleuca stands; individuals are sometimes seen in rural paddocks and around livestock.
