Pedionomus torquatus is endemic to Australia. It is recorded from north-central Victoria, eastern South Australia, southern New South Wales around the Riverina and west-central Queensland (Baker-Gabb 2002; Barrett et al. 2003). The population is estimated to vary from c.2000 birds during periods of widespread drought to c.5500â7000 birds after several successive seasons with favourable conditions (Baker-Gabb 2002). A significant proportion of the population occurs in the Riverina region. Here, the population may be as high as 5,500 birds after good years, but can decline to about 1,000 in poor years (Baker-Gabb 2002). The population in west-central Queensland is estimated at 1000 birds, and the north-central Victorian and South Australia populations may hold 500 birds each during good years (Maher and Baker-Gabb 1993; Baker-Gabb 2002). Surveys in the Riverina reveal an on-going decline, with an encounter rate of 0.13 birds/km in 4,286 km of monitoring during the dry years of 2001â2007, compared to 0.3 birds/km in 2,121 km of monitoring in the wetter years of 1984â1986 (Baker-Gabb 2002; Birds Australia 2008).
