Family of birds

Psophodidae is a family of passerine birds native to Australia and nearby areas. It has a complicated taxonomic history and different authors vary in which birds they include in the family. In the strictest sense, it includes only the five or six species of whipbirds and wedgebills (Psophodes and Androphobus), but some authors also include the quail thrushes (Cinclosoma), eight species of ground dwelling birds found in Australia and New Guinea, and the jewel babblers (Ptilorrhoa), three or four species found in rainforest in New Guinea. Others place them in their own family, the Cinclosomatidae. The Malaysian rail babbler (Eupetes macrocerus) was formerly sometimes placed in this family, which would then be called Eupetidae.

The quail thrushes, jewel babblers, whipbirds and wedgebills were traditionally included with the logrunners (Orthonyx) in the family Orthonychidae. Sometimes the Malaysian rail babbler and blue capped ifrit (Ifrita kowaldi) were also included in the family. In 1985, Sibley and Ahlquist found that the logrunners were not related to the others and included only the logrunners in the Orthonychidae. They treated the others as the subfamily Cinclosomatinae within their expanded family Corvidae. A number of authors later treated the quail thrushes and allies as the family Cinclosomatidae, a name first coined by Gregory Mathews in 1921–1922. However, if the whipbirds are included in the family, the older name Psophodidae Bonaparte, 1854 has priority. If the Malaysian rail babbler is also included, the name Eupetidae Bonaparte, 1850 has priority. Another study found the quail thrushes and jewel babblers to be related to each other but did not show them to have a close relationship with Psophodes or Ifrita.

Whipbirds and wedgebills are 19–31 cm long. They are mainly olive green or brown in colour and have a crest.

The whipbirds and wedgebills are all found in Australia, occurring in a range of habitats from rainforest to arid scrub.

They are terrestrial birds which fly fairly weakly and prefer to squat or run when disturbed. In the desert, quail thrushes also eat some seeds. They build a cup shaped nest among shrubs or on the ground. Two or three eggs are laid.
