Input: Context: Attwater's prairie chicken ("Tympanuchus cupido attwateri") is a highly endangered subspecies of the greater prairie chicken that is native to coastal Texas and Louisiana in the United States., The Galliformes are an order of heavy-bodied ground-feeding birds that includes turkey, grouse, chicken, New World quail and Old World quail, ptarmigan, partridge, pheasant, junglefowl and the Cracidae. The name derives from "gallus", Latin for "cock" or "rooster". Common names are gamefowl or gamebirds, landfowl, gallinaceous birds, or galliforms. "Wildfowl" or just "fowl" are also often used for the Galliformes, but usually these terms also refer to waterfowl (Anseriformes), and occasionally to other commonly hunted birds. This group has about 290 species, one or more of which are found in essentially every part of the world's continents (except for the innermost deserts and perpetual ice). They are rarer on islands, and in contrast to the closely related waterfowl, are essentially absent from oceanic islandsunless introduced there by humans. Several species have been domesticated during their long and extensive relationships with humans., The chicken ("Gallus gallus domesticus") is a type of domesticated fowl, a subspecies of the red junglefowl. It is one of the most common and widespread domestic animals, with a population of more than 19 billion as of 2011. Humans keep chickens primarily as a source of food, consuming both their meat and their eggs., Grouse are a group of birds from the order Galliformes, in the family Phasianidae. Grouse are frequently assigned to the subfamily Tetraoninae (sometimes Tetraonidae), a classification supported by mitochondrial DNA sequence studies, and applied by the American Ornithologists' Union, ITIS, and others. Grouse inhabit temperate and subarctic regions of the Northern Hemisphere, from pine forests to moorland and mountainside, from 83N (rock ptarmigan in northern Greenland) to 28N (Attwater's prairie chicken in Texas)., The Phasianidae are a family of heavy, groundliving birds which includes pheasants, partridges, junglefowl, chickens, Old World quail, and peafowl. The family includes many of the most popular gamebirds. The family is a large one, and is occasionally broken up into two subfamilies, the Phasianinae, and the Perdicinae. Sometimes, additional families and birds are treated as part of this family. For example, the American Ornithologists' Union includes Tetraonidae (grouse), Numididae (guineafowl), and Meleagrididae (turkeys) as subfamilies in Phasianidae., Tetrao is a genus of birds in the grouse subfamily. The genus name is derived from the Latin name of a gamebird, probably the black grouse., Texas is the second largest state in the United States by both area and population. Geographically located in the south central part of the country, Texas shares borders with the U.S. states of Louisiana to the east, Arkansas to the northeast, Oklahoma to the north, New Mexico to the west, and the Mexican states of Chihuahua, Coahuila, Nuevo Leon, and Tamaulipas to the southwest, while the Gulf of Mexico is to the southeast., Falcipennis is a genus of birds in the grouse family that comprises three very similar species : Siberian grouse , Falcipennis falcipennis Spruce grouse , Falcipennis canadensis Franklin 's grouse , Falcipennis franklinii Both inhabit northern coniferous forests and live on conifer needles during the winter . Both have breeding systems with dispersed male territories , intermediate between the leks of some grouse and the monogamy of others ., The rock ptarmigan (') is a medium-sized gamebird in the grouse family. It is known simply as the ptarmigan in the UK and in Canada, where it is the official bird for the territory of Nunavut, Canada, and the official game bird for the province of Newfoundland and Labrador, Canada, and colloquially as the snow chicken"' in the United States. In Japan, it is known as the "raich" (), which means "thunder bird". It is the official bird of Gifu, Nagano, and Toyama Prefectures and is a protected species nationwide., Subject: falcipennis, Relation: parent_taxon, Options: (A) anseriformes (B) area (C) galliformes (D) gallus (E) gallus gallus (F) grouse (G) numididae (H) perdicinae (I) phasianidae (J) phasianinae (K) tetrao (L) tympanuchus
