Pedionomus torquatus
The Plains-wanderer, Pedionomus torquatus, is one of the world's most unique and critically endangered birds, being the sole member of its distinct family, Pedionomidae, within the order Charadriiformes. Superficially resembling a small quail, this compact ground-dwelling bird measures 15-19 cm (6-7.5 in) in length and weighs between 40-95 grams. It exhibits striking reverse sexual dimorphism: the female is larger (55-95 g vs. male 40-80 g) and more brightly colored, sporting a conspicuous bl...
Found exclusively in sparse, native grasslands with a low-to-moderate tussock cover and bare ground, typically in temperate and semi-arid lowlands of southeastern Australia.

They are primarily solitary or found in pairs during the breeding season, with females being highly territorial, defending patches of grassland. Foraging involves a...
The Plains-wanderer is endemic to southeastern Australia, with its highly fragmented distribution primarily confined to sparse, native grasslands across specific regions. Historically, its range included eastern South Australia, central and northern Victoria, central and western New South Wales, ...
