The orange-bellied parrot is a small grass parrot of southern Australia and one of only a handful of migratory parrot species in the world. Each year the entire wild population breeds in a single area of remote southwestern Tasmania, then crosses Bass Strait to winter along the coast of mainland southeastern Australia [BirdLife 2024]. Decades of habitat change and the demographic fragility of a very small population have left the species among the most imperiled birds on Earth, with fewer than 100 mature individuals estimated in the wild [IUCN 2018].
Despite that precarious standing, an intensive multi-agency recovery effort has kept the species in existence and, in recent seasons, supported modest growth. The wild population recovered from a low point of roughly 14–17 birds in 2016 to dozens of returning adults by the mid-2020s [Morrison et al. 2025; NRE Tas 2025].
Biology and Identification
The orange-bellied parrot is a compact grass parrot about 20–22 cm in length [Higgins 1999; Australian Museum 2022]. Adult males have bright grass-green upperparts, yellow underparts, and a distinctive orange patch on the lower belly, with a two-toned blue frontal band across the forehead and blue outer wing feathers [BirdLife 2024]. Females and immature birds are duller, with a smaller and paler belly patch [BirdLife 2024]. The species is one of only three regularly migratory parrots, alongside the swift parrot and the blue-winged parrot, a close relative within the genus Neophema [Higgins 1999].
The diet is dominated by the seeds of small coastal and saltmarsh plants. On the breeding grounds and during migration, birds feed heavily on the seeds of glassworts and other low-growing herbs and sedges, foraging on or near the ground [BirdLife 2024]. Birds nest in tree hollows, and the recovery program supplements natural hollows with monitored nest boxes [NRE Tas 2025].
Habitat and Range
Breeding is confined to a small area of buttongrass moorland and adjacent forest in southwestern Tasmania, centered on the Melaleuca region within the Tasmanian Wilderness World Heritage Area [NRE Tas 2020]. After the breeding season the population migrates north across Bass Strait to overwinter on the coasts of Victoria and South Australia, using saltmarsh, coastal dune, and estuarine vegetation [BirdLife 2024; Australian Museum 2022]. To protect this sensitive species, NRWL does not publish precise nest, roost, or movement locations; the recovery program describes the breeding range only in general terms around the Melaleuca region [NRE Tas 2020].
This extreme reliance on a single breeding locality and a narrow band of coastal wintering habitat is a defining feature of the species' rarity. Loss, fragmentation, and degradation of coastal wintering vegetation, together with altered fire regimes that affect the structure of breeding-ground moorland, have reduced the quality and extent of suitable habitat over the long term [NRE Tas 2020].
Conservation Status
The orange-bellied parrot is assessed as Critically Endangered on the IUCN Red List, most recently assessed in 2018 (assessment e.T22685203A130894893) [IUCN 2018]. The IUCN estimates the wild population at fewer than 100 mature individuals and records the overall population trend as decreasing [IUCN 2018]. The species is also listed as Critically Endangered nationally under Australia's Environment Protection and Biodiversity Conservation Act 1999 and under Tasmanian and Victorian state legislation [NRE Tas 2020].
Annual census data from the recovery program provide a fine-grained picture of the small wild population. After a low of roughly 14–17 birds in 2016, the number of birds returning to the breeding grounds rose over subsequent seasons, with 86 birds confirmed returned from migration following the 2024–25 season [NRE Tas 2025]. These figures remain small enough that year-to-year fluctuations carry real extinction risk.
Threats
The principal threats reflect both habitat loss and the inherent fragility of a tiny population [IUCN 2018; NRE Tas 2020]. Degradation and fragmentation of coastal wintering habitat reduce food availability during a demanding part of the annual cycle, while changes to fire regimes alter breeding-ground vegetation [NRE Tas 2020]. Low first-year survival limits recruitment, and reduced genetic diversity lowers the population's capacity to adapt to environmental change [IUCN 2018; Morrison et al. 2025].
Disease is a documented and serious concern. Beak and feather disease virus (BFDV), the agent of psittacine beak and feather disease, has been detected spilling over into the wild population, and a novel BFDV genotype was identified in wild orange-bellied parrots [Peters et al. 2014]. Because the species occurs at such low numbers, an outbreak could have outsized effects, and disease screening is now integral to managing the captive insurance population [Peters et al. 2014]. Genomic studies have further documented a measurable loss of genome-wide and immune-related diversity in this near-extinct parrot, underscoring the long-term genetic risks [Morrison et al. 2025].
What Is Being Done
A long-running national recovery program coordinates conservation across the breeding and wintering ranges. Core actions include intensive monitoring at the breeding grounds, provision and management of nest boxes, supplementary feeding, and an insurance captive-breeding population held across several Australian facilities that supplies birds for release [NRE Tas 2025]. In the 2024–25 season, monitored nest boxes at the breeding grounds produced a minimum of 99 fledglings, and released captive-bred juveniles were among the birds confirmed returning from migration [NRE Tas 2025].
Habitat protection is supported by the breeding area's location within a World Heritage wilderness, and disease management protocols aim to reduce the spread of BFDV between captive and wild birds [Peters et al. 2014; NRE Tas 2020]. Research on population genetics and demographic modeling continues to inform release and management decisions [Morrison et al. 2025].
How You Can Help
Support for the orange-bellied parrot is most effective when channeled through the established recovery effort and the conservation organizations that fund and conduct the work, such as BirdLife Australia and the Tasmanian and Australian government programs [BirdLife 2024; NRE Tas 2025]. Members of the public who live near or visit known wintering areas can contribute by reporting verified sightings to recovery-program channels and by supporting protection of coastal saltmarsh habitat [NRE Tas 2025]. Learning about and sharing accurate information on the species also helps sustain the public attention that long-term recovery programs depend on.
