Systematics History

Monotypic.

Subspecies

Monotypic.

Distribution

Interior W & C Australia. Irregular in most of range, with probable core areas around L Tobin (NC Western Australia) and Great Victoria Desert.

Habitat

Sandy deserts with hummock grassland of Triodia and Plectrachne, usually with a shrub layer, stands of Casuarina in sandy country, Acacia scrublands and eucalypts  , notably Eucalyptus camaldulensis, bordering watercourses, this last commonly used for nesting.

Movement

Irruptive and/or nomadic; recent analysis suggests a core population around Lake Tobin, in the east of the Great Sandy Desert, from which birds range out far more widely over several years when conditions permit.

Diet and Foraging

Seeds of grasses and herbaceous plants, notably spinifex, but also Danthonia bipartitaPortulaca oleraceaStenopetalum anfractumRhynchelytrum repens and Calandrinia; seeds and perhaps blossoms of Acacia and Casuarina, taking green leaflets of latter, and seen feeding on leaves of Codonocarpus cotinifolius, flowers of Crotalaria cunninghamiGrevillea wickhamii and Hakea suberea.

Sounds and Vocal Behavior

Not well documented. Commonest vocalizations a loud “krreee” and a sharp “queet”. Also quiet chirrups and lower-pitched notes when feeding.

Breeding

Recorded Sept–Dec, but dependent young also seen in Jul; probably at any time of year after rainfall. Nest in hollow limb  or hole in tree, usually a riverine eucalypt but sometimes Casuarina; sometimes colonial, with up to 10 nests in one tree. During a population irruption in S Northern Territory, at least 21 active nests detected in Aug–Nov and one in Jan; all in mature Eucalyptus gongylocarpa, with entrances at c. 6·5 m above the ground on average (range 4·4–9·9 m) . Eggs  4–6; incubation lasts c. 21 days.

Conservation Status

 

Not globally threatened. Currently considered Near Threatened, and previously, Vulnerable. CITES II. Population very difficult to assess in a very scarce, apparently nomadic species with a large range; possibly no major decline but decline and extinction of other sympatric non-avian taxa, and absence of records of large numbers since 1963 ,caused concern; in Jul 1993 almost 300 were counted in one part of the Lake Tobin area.

Possible that man-made changes to its habitat may have favoured more water-dependent competitors. No fewer than 25,000 held in captivity in Australia.
