The plains wanderer (Pedionomus torquatus) is the only species in this family. It is a ground-dwelling bird that lives on the plains of eastern Australia.

The plains wanderer looks like a small quail. It has a small bill; mottled brown, tan, white, and black feathers; and a cinnamon brown patch on its chest. The plains wanderer eats seeds, spiders, and insects.

There are around 8,000 plains wanderers in Australia, and they are a protected species.
