Cinclosomatidae
Cinclosomatidae 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. It includes at least the quail-thrushes (Cinclosoma), 8 species of ground-dwelling birds found in Australia and New Guinea. The jewel-babblers (Ptilorrhoa), 4 species found in rainforest in New Guinea, also seem to belong in this family.
The whipbirds and wedgebills ( Psophodes and Androphobus) are often included in which case the name Psophodidae has priority as the name of the family. The Malaysian rail-babbler (Eupetes macrocerus) was formerly sometimes placed in this family which would then be called Eupetidae.
