The wedge-tailed grouse or wood rock grouse ( Tetraophasis ) are a genus in the pheasant-like family. They are relatively large chicken birds with a wedge-shaped tail. This consists of 18 feathers while the tail of most pheasant-like species consists of fourteen feathers. The body length of the wedge-tailed chickens is 48 to 50 centimeters, with the females remaining slightly smaller than the males. Otherwise there is no noticeable gender dimorphism . Both species are very similar in their appearance. They occur exclusively in China, but their range does not overlap.
The population of both species was classified in the IUCN Red List of Threatened Species in 2016 as “ Least Concern (LC) ” = “not endangered”.
