Perdix is a genus of Galliform gamebirds known collectively as the 'true partridges'. The genus name is the Latin for "partridge", and is itself derived from Ancient Greek perdix. These birds are unrelated to the subtropical species that have been named after the partridge due to similar size and morphology. There are representatives of Perdix in most of temperate Europe and Asia. One member of the genus, the grey partridge, has been introduced to the United States and Canada for the purpose of hunting. They are closely related to grouse, koklass, quail and pheasants
