Given the question: Information: - The red grouse , Lagopus lagopus scotica , is a medium - sized bird of the grouse family which is found in heather moorland in Great Britain and Ireland . It is usually classified as a subspecies of the willow ptarmigan but is sometimes considered to be a separate species , Lagopus scotica . It is also known as the moorcock , moorfowl or moorbird . - Canada (French: ) is a country in the northern half of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering , making it the world's second-largest country by total area and the fourth-largest country by land area. Canada's border with the United States is the world's longest land border. The majority of the country has a cold or severely cold winter climate, but southerly areas are warm in summer. Canada is sparsely populated, the majority of its land territory being dominated by forest and tundra and the Rocky Mountains. About four-fifths of the country's population of 36 million people is urbanized and live near the southern border. Its capital is Ottawa, its largest city is Toronto; other major urban areas include Montreal, Vancouver, Calgary, Edmonton, Quebec City, Winnipeg and Hamilton. - Willows, also called sallows, and osiers, form the genus Salix, around 400 species of deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions of the Northern Hemisphere. Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow (from Old English "sealh", related to the Latin word "salix", willow). Some willows (particularly arctic and alpine species) are low-growing or creeping shrubs; for example, the dwarf willow ("Salix herbacea") rarely exceeds in height, though it spreads widely across the ground. - BIRCH (balanced iterative reducing and clustering using hierarchies) is an unsupervised data mining algorithm used to perform hierarchical clustering over particularly large data-sets. An advantage of BIRCH is its ability to incrementally and dynamically cluster incoming, multi-dimensional metric data points in an attempt to produce the best quality clustering for a given set of resources (memory and time constraints). In most cases, BIRCH only requires a single scan of the database. - The willow ptarmigan ("Lagopus lagopus") is a bird in the grouse subfamily Tetraoninae of the pheasant family Phasianidae. It is also known as the willow grouse and in Ireland and Britain, where it was previously believed to be a separate species, as the red grouse. It is a sedentary species, breeding in birch and other forests and moorlands in northern Europe, the tundra of Scandinavia, Siberia, Alaska and northern Canada, in particular in the province of Newfoundland and Labrador. It is the state bird of Alaska. In the summer the birds are largely brown, with dappled plumage, but in the winter they are white with some black feathers in their tails (British populations do not adopt a winter plumage). The species has remained little changed from the bird that roamed the tundra during the Pleistocene. Nesting takes place in the spring when clutches of four to ten eggs are laid in a scrape on the ground. The chicks are precocial and soon leave the nest and while they are young, both parents play a part in caring for them. The chicks eat insects and young plant growth while the adults are completely herbivorous, eating leaves, flowers, buds, seeds and berries during the summer and largely subsisting on the buds and twigs of willow and other dwarf shrubs and trees during the winter. - Sedgemoor is a low-lying area of land in Somerset, England. It lies close to sea level south of the Polden Hills, historically largely marsh (or "moor" in its older sense). The eastern part is known as King's Sedgemoor, and the western part West Sedgemoor. Sedgemoor is part of the area now known as the Somerset Levels and Moors. Historically the area was known as the site of the Battle of Sedgemoor. - Insects (from Latin ', a calque of Greek ['], "cut into sections") are a class of invertebrates within the arthropod phylum that have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. They are the most diverse group of animals on the planet, including more than a million described species and representing more than half of all known living organisms. The number of extant species is estimated at between six and ten million, and potentially represent over 90% of the differing animal life forms on Earth. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, a habitat dominated by another arthropod group, crustaceans. - A wetland is a land area that is saturated with water, either permanently or seasonally, such that it takes on the characteristics of a distinct ecosystem. The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique hydric soil. Wetlands play a number of roles in the environment, principally water purification, flood control, carbon sink and shoreline stability. Wetlands are also considered the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal life. - 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. - Plumage ("feather") refers both to the layer of feathers that cover a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies, and may vary with age classes. Within species there can be different colour morphs. - Honshu had a population of 103 million , mostly concentrated in the coastal lowlands, notably in the Kant plain where 25% of the total population resides in the Greater Tokyo Area. As the historical center of Japanese culture and political power, the island includes several past Japanese capitals, including Kyoto, Nara, and Kamakura. Much of the island's southern shore forms part of the Taiheiy Belt, a megalopolis that spans several of the Japanese islands. - 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. - Newfoundland and Labrador (; Innu: "Akamassiss"), is the most easterly province of Canada. Situated in the country's Atlantic region, it comprises the island of Newfoundland and mainland Labrador to the northwest, with a combined area of . In 2013, the province's population was estimated at 526,702. About 92% of the province's population lives on the island of Newfoundland (and its neighbouring smaller islands), of whom more than half live on the Avalon Peninsula. The province is Canada's most linguistically homogeneous, with 97.6% of residents reporting English (Newfoundland English) as their mother tongue in the 2006 census. Historically, Newfoundland was also home to unique varieties of French and Irish, as well as the extinct Beothuk language. In Labrador, local dialects of Innu-aimun and Inuktitut are also spoken. - Moorland or moor is a type of habitat found in upland areas in temperate grasslands, savannas, and shrublands and montane grasslands and shrublands biomes, characterised by low-growing vegetation on acidic soils. Moorland nowadays generally means uncultivated hill land (such as Dartmoor in South West England), but includes low-lying wetlands (such as Sedgemoor, also South West England). It is closely related to heath although experts disagree on precisely what distinguishes the types of vegetation. Generally, moor refers to highland, high rainfall zones, whereas heath refers to lowland zones which are more likely to be the result of human activity. - Great Britain, also known as Britain, is a large island in the north Atlantic Ocean off the northwest coast of continental Europe. With an area of , Great Britain is the largest European island and the ninth-largest in the world. In 2011 the island had a population of about 61million people, making it the world's third-most populous island after Java in Indonesia and Honshu in Japan. The island of Ireland is situated to the west of it, and together these islands, along with over 1,000 smaller surrounding islands, comprise the British Isles archipelago. - Alaska is a U.S. state located in the northwest extremity of North America. The Canadian administrative divisions of British Columbia and Yukon border the state to the east; its most extreme western part is Attu Island; it has a maritime border with Russia to the west across the Bering Strait. To the north are the Chukchi and Beaufort seasthe southern parts of the Arctic Ocean. The Pacific Ocean lies to the south and southwest. Alaska is the largest state in the United States by area, the 3rd least populous and the least densely populated of the 50 United States. Approximately half of Alaska's residents (the total estimated at 738,432 by the U.S. Census Bureau in 2015) live within the Anchorage metropolitan area. Alaska's economy is dominated by the fishing, natural gas, and oil industries, resources which it has in abundance. Military bases and tourism are also a significant part of the economy. - 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. - 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 British Isles are a group of islands off the north-western coast of continental Europe that consist of the islands of Great Britain, Ireland and over six thousand smaller isles. Situated in the North Atlantic, the islands have a total area of approximately 315,159km, and a combined population of just under 70 million. Two sovereign states are located on the islands: Ireland (which covers roughly five-sixths of the island with the same name) and the United Kingdom of Great Britain and Northern Ireland. The British Isles also include three Crown Dependencies: the Isle of Man and, by tradition, the Bailiwick of Jersey and the Bailiwick of Guernsey in the Channel Islands, although the latter are not physically a part of the archipelago. - 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. - 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. - Dartmoor is an area of moorland in southern Devon, England. Protected by National Park status as Dartmoor National Park, it covers . - 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 Atlantic Ocean is the second largest of the world's oceans with a total area of about . It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World". - South West England is one of nine official regions of England. It is the largest in area, covering and the counties of Gloucestershire, Bristol, Wiltshire, Somerset, Dorset, Devon and Cornwall, as well as the Isles of Scilly. Five million people live in South West England. After reading the paragraphs above, choose the best answer for the entity that related to 'red grouse' with the relationship of 'parent taxon'.
