Please answer the following question: Information:  - South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere. It is also considered a subcontinent of the Americas, which is the model used in nations that speak Romance languages. The reference to South America instead of other regions (like Latin America or the Southern Cone) has increased in the last decades due to changing geopolitical dynamics (in particular, the rise of Brazil).  - The black geese of the genus Branta are waterfowl belonging to the true geese and swans subfamily Anserinae. They occur in the northern coastal regions of the Palearctic and all over North America, migrating to more southernly coasts in winter, and as resident birds in the Hawaiian Islands. Alone in the Southern Hemisphere, a self-sustaining feral population derived from introduced Canada geese is also found in New Zealand.  - Tierra del Fuegoliterally "Fire Land", formerly "Isla de Xativa" and also known as Isla Grande de Tierra del Fuegois an island near the southern tip of South America from which it is separated by the Strait of Magellan. The western portion of the island (and 61.43% of the island) is in Chile (Province of Tierra del Fuego and Antártica Chilena Province), while the eastern portion (and 38.57%) is in Argentina (Tierra del Fuego Province). It forms the major landmass in an extended group of islands or archipelago also known as Tierra del Fuego.  - Patagonia is a sparsely populated region located at the southern end of South America, shared by Argentina and Chile. The region comprises the southern section of the Andes mountains as well as the deserts, steppes and grasslands east of this southern portion of the Andes. Patagonia has two coasts; a western one towards the Pacific Ocean and an eastern one towards the Atlantic Ocean.  - East Falkland is the largest island of the Falklands in the South Atlantic having an area of or 54% of the total area of the Falklands. The island consists of two main land masses, the more southerly of which is known as Lafonia, joined by a narrow isthmus that was the scene of the Battle of Goose Green during the Falklands War.  - A continent is one of several very large landmasses on Earth. Generally identified by convention rather than any strict criteria, up to seven regions are commonly regarded as continents. Ordered from largest in size to smallest, they are: Asia, Africa, North America, South America, Antarctica, Europe, and Australia. In geology, areas of continental crust include regions covered with water.  - West Falkland is the second largest of the Falkland Islands in the South Atlantic. It is a hilly island, separated from East Falkland by the Falkland Sound. Its area is , 37% of the total area of the islands. Its coastline is long.  - Beagle Channel is a strait in Tierra del Fuego Archipelago on the extreme southern tip of South America partly in Chile and partly in Argentina. The channel separates the larger main island of Isla Grande de Tierra del Fuego from various smaller islands including the islands of Picton, Lennox and Nueva; Navarino; Hoste; Londonderry; and Stewart. The channel's eastern area forms part of the border between Chile and Argentina and the western area is entirely within Chile.  - The Andes or Andean Mountains are the longest continental mountain range in the world. They are a continuous range of highlands along the western edge of South America. This range is about long, about wide (widest between 18° south and 20° south latitude), and of an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Argentina and Chile.  - Chile, officially the Republic of Chile, is a South American country occupying a long, narrow strip of land between the Andes to the east and the Pacific Ocean to the west. It borders Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage in the far south. Chilean territory includes the Pacific islands of Juan Fernández, Salas y Gómez, Desventuradas, and Easter Island in Oceania. Chile also claims about of Antarctica, although all claims are suspended under the Antarctic Treaty.  - Owls are birds from the order Strigiformes, which includes about 200 species of mostly solitary and nocturnal birds of prey typified by an upright stance, a large, broad head, binocular vision, binaural hearing, sharp talons, and feathers adapted for silent flight. Exceptions include the diurnal northern hawk-owl and the gregarious burrowing owl.  - The Falkland Islands are an archipelago in the South Atlantic Ocean on the Patagonian Shelf. The principal islands are about east of South America's southern Patagonian coast, at a latitude of about 52°S. The archipelago, with an area of , comprises East Falkland, West Falkland and 776 smaller islands. As a British overseas territory, the Falklands have internal self-governance, and the United Kingdom takes responsibility for their defence and foreign affairs. The islands' capital is Stanley on East Falkland.  - 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".  - The Anserinae are a subfamily in the waterfowl family Anatidae. It includes the swans and true geese. Under alternative systematical concepts (see e.g., Terres & NAS, 1991), it is split into two subfamilies, the Anserinae contain the geese and the ducks, while the Cygninae contain the swans.  - The shelducks, genus Tadorna, are a group of large birds in the Tadorninae subfamily of the Anatidae, the biological family that includes the ducks and most duck-like waterfowl such as the geese and swans.  - Grasslands are areas where the vegetation is dominated by grasses (Poaceae), however sedge (Cyperaceae) and rush (Juncaceae) families can also be found. Grasslands occur naturally on all continents except Antarctica. Grasslands are found in most ecoregions of the Earth. For example, there are five terrestrial ecoregion classifications (subdivisions) of the temperate grasslands, savannas, and shrublands biome (ecosystem), which is one of eight terrestrial ecozones of the Earth's surface.  - The Patagones or Patagonian giants are a mythical race of people, who first began to appear in early European accounts of the then little-known region and coastline of Patagonia. They were supposed to have exceeded at least double normal human height, some accounts giving heights of or more. Tales of these improbable people would take a hold over European concepts of the region for some 250 years, until they were substantially debunked at the end of the 18th century.  - The Tadorninae is the shelduck-sheldgoose subfamily of the Anatidae, the biological family that includes the ducks and most duck-like waterfowl such as the geese and swans.  - Southern Cone is a geographic region composed of the southernmost areas of South America, south of and around the Tropic of Capricorn. Traditionally, it covers Argentina, Chile and Uruguay, bounded on the west by the Pacific Ocean, and south to the junction between the Pacific and Atlantic Oceans, which is the closest continental area of Antarctica (1000 km). In terms of social and political geography, the Southern Cone comprises Argentina, Chile, Uruguay, Southern Brazil and sometimes Paraguay.  - Tierra del Fuego (; Spanish for "Land of Fire") is an archipelago off the southernmost tip of the South American mainland, across the Strait of Magellan. The archipelago consists of the main island, Isla Grande de Tierra del Fuego, with an area of , and a group of many islands, including Cape Horn and Diego Ramírez Islands. Tierra del Fuego is divided between Chile and Argentina, with the latter controlling the eastern half of the main island and the former the western half plus the islands south of Beagle Channel. The southernmost extent of the archipelago is at about latitude 55 S.  - Geese are waterfowl belonging to the tribe Anserini of the family Anatidae. This tribe comprises the genera "Anser" (the grey geese), "Branta" (the black geese) and "Chen" (the white geese). Some other birds, mostly related to the shelducks, have "goose" as part of their names. More distantly related members of the family Anatidae are swans, most of which are larger than true geese, and ducks, which are smaller.  - Duck is the common name for a large number of species in the waterfowl family Anatidae, which also includes swans and geese. The ducks are divided among several subfamilies in the family Anatidae; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species) but a form taxon, since swans and geese are not considered ducks. Ducks are mostly aquatic birds, mostly smaller than the swans and geese, and may be found in both fresh water and sea water.  - The Anatidae are the biological family of birds that includes ducks, geese, and swans. The family has a cosmopolitan distribution, occurring on all the world's continents. These birds are adapted for swimming, floating on the water surface, and in some cases diving in at least shallow water. The family contains around 146 species in 40 genera. (The magpie goose is no longer considered to be part of the Anatidae, but is placed in its own family Anseranatidae.)  - Birds (Aves), also known as avian dinosaurs, are a group of endothermic vertebrates, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. They rank as the class of tetrapods with the most living species, at approximately ten thousand, with more than half of these being passerines, sometimes known as perching birds or, less accurately, as songbirds.  - The coscoroba swan ("Coscoroba coscoroba") is a species of waterfowl endemic to southern South America. It is the smallest of the birds called "swans", but still a large species of waterfowl. It belongs to the subfamily Anserinae in the family of ducks, swans, and geese, Anatidae. It is placed in the monotypic genus "Coscoroba". The coscoroba swan is traditionally considered as an early branch from the common ancestor leading to true geese and swans, and recently genetic studies have associated a phylogenetic relationship between this species and Cape Barren goose ("Cereopsis novaehollandiae") as sister groups.  - Swans are birds of the family Anatidae within the genus Cygnus. The swans' close relatives include the geese and ducks. Swans are grouped with the closely related geese in the subfamily Anserinae where they form the tribe Cygnini. Sometimes, they are considered a distinct subfamily, Cygninae. There are six or seven species of swan in the genus "Cygnus"; in addition there is another species known as the coscoroba swan, although this species is no longer considered one of the true swans. Swans usually mate for life, though "divorce" does sometimes occur, particularly following nesting failure, and if a mate dies, the remaining swan will take up with another. The number of eggs in each clutch ranges from three to eight.  - Waterfowl are certain wildfowl of the order Anseriformes, especially members of the family Anatidae, which includes ducks, geese, and swans. Some definitions of the term 'waterfowl' include the saltwater shorebirds or waders, gulls, pelicans, and herons, as well as seabirds such as the albatross, but 'fowl' especially refers to birds used by humans for game. They have historically been an important food source, and continue to be hunted as game, or raised as poultry for meat and eggs and are sometimes kept as pets.  - Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America. As the world's fifth-largest country by both area and population, it is the largest country to have Portuguese as an official language and the only one in the Americas. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of . It borders all other South American countries except Ecuador and Chile and covers 47.3% of the continent's land area. Its Amazon River basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. This unique environmental heritage makes Brazil one of 17 megadiverse countries, and is the subject of significant global interest and debate regarding deforestation and environmental protection.  - Argentina, officially the Argentine Republic, is a federal republic in the southern half of South America. Sharing the bulk of the Southern Cone with its neighbor Chile to the west, the country is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. With a mainland area of , Argentina is the eighth-largest country in the world, the second largest in Latin America, and the largest Spanish-speaking one. The country is subdivided into twenty-three provinces (singular "provincia") and one autonomous city ("ciudad autónoma"), Buenos Aires, which is the federal capital of the nation as decided by Congress. The provinces and the capital have their own constitutions, but exist under a federal system.  - The kelp goose ( Spanish : Caranca or Cauquén Marino ) , Chloephaga hybrida , is a member of the duck , goose and swan family Anatidae . It is in the shelduck subfamily Tadorninae . It can be found in the Southern part of South America ; in Patagonia , Tierra del Fuego , and the Falkland Islands .
