Justification of Red List category
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence under 20,000 km² combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (under 10,000 mature individuals with a continuing decline estimated to be over 10% in ten years or three generations, or with a specified population structure). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (over 30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern. The status of this species was recently reassessed against the IUCN Red List criteria at national level for the Action Plan for Australian Birds 2020 (Garnet and Baker 2021), and not found to approach or meet the thresholds for threatened status, thereby supporting its continuing treatment as globally Least Concern.
Population justification
The global population is estimated to be 20,000 individuals (Garnett and Crowley 2000). Global population trends have not been quantified, but populations appear to be stable, with no recent declines (Garnett and Crowley 2000).
Trend justification
Global population trends have not been quantified, but populations appear to be stable, with no recent declines (Garnett and Crowley 2000).
This species is endemic to the Northern Territory, Australia. Its historical range extended between about Pine Creek in the west to the McArthur River in the east, and Melville, Banyan and Bathurst islands. However, its range has contracted, and it has not been seen in the McArthur River since 1913, it has been restricted to the mainland since the 1950s, and is now absent from the north coastal plain east of South Alligator River.
The species remains common in areas under Aboriginal and national park management, where grazing is minimal and burning programmes are in place, or around rocky slopes, where food availability into the wet season is relatively assured.
The species range has contracted, probably as a result of overgrazing and inappropriate fire regimes. Disappearance from the coastal plains may be reversed by reinstating appropriate burning and grazing regimes. The species may occasionally be illegally taken for the bird trade, but this is unlikely to pose a serious threat as the species is common in captivity and easy to breed (Garnett and Crowley 2000).
