Population justification: The population is estimated to vary from between 5,500-7,000 in good years to around 2,000 birds during periods of widespread drought (Baker-Gabb 2002, Garnett et al. 2011). It is placed in the band 1,000-2,499 mature individuals. |
|
Trend justification: Considering the declines in the area of suitable habitat, this species's population is suspected to be decreasing at an unquantified rate (Garnett and Crowley 2000). The cultivation of native grassland has virtually extinguished the species from southern South Australia and Victoria and is increasing across the Riverina. Even if left to recover, habitat remains unsuitable for decades. Where patches survive, they are often too few and dispersed to be suitable. High levels of grazing cause the desertion of an area, possibly because birds become too vulnerable to predators. It has become effectively extinct in south-west Victoria, south-east South Australia, eastern New South Wales and south-east Queensland. |
