Quail is a collective name for several genera of mid-sized birds generally placed in the order Galliformes. The collective noun for a group of quail is a flock, covey, or bevy. Old World quail are placed in the family Phasianidae, and New World quail are placed in the family Odontophoridae. The species of buttonquail are named for their superficial resemblance to quail, and form the family Turnicidae in the order Charadriiformes. The king quail, an Old World quail, often is sold in the pet trade, and within this trade is commonly, though mistakenly, referred to as a "button quail". Many of the common larger species are farm-raised for table food or egg consumption, and are hunted on game farms or in the wild, where they may be released to supplement the wild population, or extend into areas outside their natural range. In 2007, 40 million quail were produced in the U.S. New World Genus Callipepla Scaled quail, (commonly called blue quail) Callipepla squamata Elegant quail, Callipepla douglasii California quail, Callipepla californica Gambel's quail, Callipepla gambelii Genus Cyrtonyx Montezuma quail, Cyrtonyx montezumae Ocellated quail, Cyrtonyx ocellatus Genus Dactylortyx Singing quail, Dactylortyx thoracicus Genus Philortyx Banded quail, Philortyx fasciatus Genus Colinus Northern bobwhite, Colinus virginianus Black-throated bobwhite, Colinus nigrogularis Spot-bellied bobwhite, Colinus leucopogon Crested bobwhite, Colinus cristatus Genus Odontophorus Marbled wood quail, Odontophorus gujanensis Spot-winged wood quail, Odontophorus capueira Black-eared wood quail, Odontophorus melanotis Rufous-fronted wood quail, Odontophorus erythrops Black-fronted wood quail, Odontophorus atrifrons Chestnut wood quail, Odontophorus hyperythrus Dark-backed wood quail, Odontophorus melanonotus Rufous-breasted wood quail, Odontophorus speciosus Tacarcuna wood quail, Odontophorus dialeucos Gorgeted wood quail, Odontophorus strophium Venezuelan wood quail, Odontophorus columbianus Black-breasted wood quail, Odontophorus leucolaemus Stripe-faced wood quail, Odontophorus balliviani Starred wood quail, Odontophorus stellatus Spotted wood quail, Odontophorus guttatus Genus Oreortyx Mountain quail, Oreortyx pictus Genus Rhynchortyx Tawny-faced quail, Rhynchortyx cinctus Old World Genus Coturnix Common quail (also called Pharaoh, Bible, European or Nile quail), Coturnix coturnix Japanese quail, Coturnix japonica Stubble quail, Coturnix pectoralis †New Zealand quail, Coturnix novaezelandiae (extinct) Rain quail, Coturnix coromandelica Harlequin quail, Coturnix delegorguei †Canary Islands quail, Coturnix gomerae (fossil) Genus Synoicus Brown quail, Synoicus ypsilophorus Blue quail, Synoicus adansonii King quail, Synoicus chinensis Snow Mountain quail, Synoicus monorthonyx Genus Perdicula Jungle bush quail, Perdicula asiatica Rock bush quail, Perdicula argoondah Painted bush quail, Perdicula erythrorhyncha Manipur bush quail, Perdicula manipurensis Genus Ophrysia Himalayan quail, Ophrysia superciliosa (critically endangered/extinct) Quail in cookery
