The plains-wanderer (Pedionomus torquatus) is a bird in the family Pedionomidae, of which it is the only surviving species. Endemic to Australia, its historical range included Victoria, New South Wales, South Australia and the Northern Territory, but in recent years it has become endangered, with remaining known populations concentrated in the Riverina (a region in southwestern New South Wales) and western Queensland. The plains-wanderer is a quail-like ground bird, measuring 15 to 19 centimetres (5.9 to 7.5 in). The adult male is light brown above, with fawn-white underparts with black crescents. The adult female is substantially larger than the male and has a distinctive white-spotted black collar. This female plains-wanderer was photographed in the Riverina, north of the town of Deniliquin, New South Wales.Photograph credit: John Harrison
