Information: - Wildlife traditionally refers to undomesticated animal species, but has come to include all plants, fungi, and other organisms that grow or live wild in an area without being introduced by humans. - Mammals are any vertebrates within the class Mammalia (from Latin "mamma" "breast"), a clade of endothermic amniotes distinguished from reptiles and birds by the possession of a neocortex (a region of the brain), hair, three middle ear bones and mammary glands. The sister group of mammals may be the extinct "Haldanodon." The mammals represent the only living Synapsida, which together with the Sauropsida form the Amniota clade. The mammals consist of the Yinotheria including monotrema and the Theriiformes including the theria. - "Hound" is a synonym for "dog", also used in a more specific sense to refer to a type of dog used by hunters to track or chase prey. - A foxhound is a type of large hunting hound bred for strong hunting instincts , great energy , and , like all scent hounds , a keen sense of smell . In fox hunting , the foxhound 's namesake , packs of foxhounds track quarry , followed -- usually on horseback -- by the hunters , sometimes for several miles at a stretch ; moreover , foxhounds also sometimes guard sheep and houses . There are different breeds of foxhound , each often called simply Foxhound in their native countries : American Foxhound English Foxhound Dumfriesshire Foxhound Black and Tan Virginia Foxhound Welsh Hound The American Masters of Foxhounds Association recognizes these breeds of foxhounds : American , Penn - Marydel , English , and Crossbred foxhounds . - Scent hounds (or scenthounds) are a type of hound that primarily hunts by scent rather than sight. These breeds are hunting dogs and are generally regarded as having some of the most sensitive noses among canines. - A feral animal (from Latin "fera", "a wild beast") is an animal living in the wild but descended from domesticated individuals. - The domestic dog ("Canis lupus familiaris" or "Canis familiaris") is a member of genus "Canis" (canines) that forms part of the wolf-like canids, and is the most widely abundant carnivore. The dog and the extant gray wolf are sister taxa, with modern wolves not closely related to the wolves that were first domesticated. The dog was the first domesticated species and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes. - Hunting is the practice of killing or trapping animals, or pursuing or tracking them with the intent of doing so. Hunting wildlife or feral animals is most commonly done by humans for food, recreation, to remove predators that are dangerous to humans or domestic animals, or for trade. Lawful hunting is distinguished from poaching, which is the illegal killing, trapping or capture of the hunted species. The species that are hunted are referred to as game or prey and are usually mammals and birds. - H.O.R.S.E. is a form of poker commonly played at the high-stakes tables of casinos. It consists of rounds of play cycling among: - 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. - Fox hunting is an activity involving the tracking, chase, and sometimes killing of a fox, traditionally a red fox, by trained foxhounds or other scent hounds, and a group of unarmed followers led by a "master of foxhounds" ("master of hounds"), who follow the hounds on foot or on horseback. - Recreation is an activity of leisure, leisure being discretionary time. The "need to do something for recreation" is an essential element of human biology and psychology. Recreational activities are often done for enjoyment, amusement, or pleasure and are considered to be "fun". - The red fox ("Vulpes vulpes"), largest of the true foxes, has the greatest geographic range of all members of the Carnivora family, being present across the entire Northern Hemisphere from the Arctic Circle to North Africa, North America and Eurasia. It is listed as least concern by the IUCN. Its range has increased alongside human expansion, having been introduced to Australia, where it is considered harmful to native mammals and bird populations. Due to its presence in Australia, it is included among the list of the "world's 100 worst invasive species". - Poaching has traditionally been defined as the illegal capturing of wild animals, usually associated with land use rights.
