A vulture is a bird of prey that scavenges on carrion. The Old World vultures include 15 living species native to Europe, Africa, and Asia; and New World vultures are restricted to North and South America. A particular characteristic of many vultures is a bald head, devoid of feathers. This bare skin is thought to keep the head clean when feeding, and also plays an important role in thermoregulation.
Hippopotamuses are stout, naked-skinned, and semiaquatic artiodactyl mammals, possessing three-chambered stomachs and walking on four toes on each foot. While they resemble pigs physiologically, their closest living relatives are the cetaceans. Hippopotamuses are the only living members of the family Hippopotamidae.
The Accipitridae, one of the three families within the order Accipitriformes, are a family of small to large birds with strongly hooked bills and variable morphology based on diet. They feed on a range of prey items from insects to medium-sized mammals, with a number feeding on carrion and a few feeding on fruit. The Accipitridae have a cosmopolitan distribution, being found on all the world's continents and a number of oceanic island groups. Some species are migratory.
Condor is the common name for two species of New World vultures, each in a monotypic genus. The name derives from the Quechua kuntur. They are the largest flying land birds in the Western Hemisphere.
The New World vulture or condor family, Cathartidae, contains seven extant species in five genera. It includes five extant vultures and two extant condors found in warm and temperate areas of the Americas. The "New World" vultures were widespread in both the Old World and North America during the Neogene.
The griffon vulture is a large Old World vulture in the bird of prey family Accipitridae. It is also known as the Eurasian griffon. It is not to be confused with a different species, Rüppell's griffon vulture. It is closely related to the white-backed vulture.
The Egyptian vulture, also called the white scavenger vulture or pharaoh's chicken, is a small Old World vulture and the only member of the genus Neophron. It is widely distributed from the Iberian Peninsula and North Africa to India. The contrasting underwing pattern and wedge-shaped tail make it distinctive in flight as it soars in thermals during the warmer parts of the day. Egyptian vultures feed mainly on carrion but are opportunistic and will prey on small mammals, birds, and reptiles. They also feed on the eggs of other birds, breaking larger ones by tossing a large pebble onto them.
The black vulture, also known as the American black vulture, is a bird in the New World vulture family whose range extends from the northeastern United States to Peru, Central Chile and Uruguay in South America. Although a common and widespread species, it has a somewhat more restricted distribution than its compatriot, the turkey vulture, which breeds well into Canada and south to Tierra del Fuego. It is the only extant member of the genus Coragyps, which is in the family Cathartidae. Despite the similar name and appearance, this species is unrelated to the Eurasian black vulture, an Old World vulture in the family Accipitridae. It inhabits relatively open areas which provide scattered forests or shrublands. With a wingspan of 1.5 m (4.9 ft), the black vulture is a large bird though relatively small for a vulture. It has black plumage, a featherless, grayish-black head and neck, and a short, hooked beak.
The cinereous vulture is a large raptorial bird that is distributed through much of temperate Eurasia. It is also known as the black vulture, monk vulture, or Eurasian black vulture. It is a member of the family Accipitridae, which also includes many other diurnal raptors such as kites, buzzards and harriers. It is one of the two largest Old World vultures, attaining a maximum size of 14 kg,, 1.2 m long and 3.1 m across the wings.
The California condor is a New World vulture and the largest North American land bird. It became extinct in the wild in 1987, but has since been reintroduced to northern Arizona and southern Utah, the coastal mountains of central and southern California, and northern Baja California. Although four other fossil members are known, it is the only surviving member of the genus Gymnogyps. The species is listed by the IUCN as critically endangered.
The king vulture is a large bird found in Central and South America. It is a member of the New World vulture family Cathartidae. This vulture lives predominantly in tropical lowland forests stretching from southern Mexico to northern Argentina. It is the only surviving member of the genus Sarcoramphus, although fossil members are known.
Homo heidelbergensis is an extinct species or subspecies of archaic human which existed during the Middle Pleistocene. It was subsumed as a subspecies of H. erectus in 1950 as H. e. heidelbergensis, but towards the end of the century, it was more widely classified as its own species. It is debated whether or not to constrain H. heidelbergensis to only Europe or to also include African and Asian specimens, and this is further confounded by the type specimen being a jawbone, because jawbones feature few diagnostic traits and are generally missing among Middle Pleistocene specimens. Thus, it is debated if some of these specimens could be split off into their own species or a subspecies of H. erectus. Because the classification is so disputed, the Middle Pleistocene is often called the "muddle in the middle".

Megaloceros is an extinct genus of deer whose members lived throughout Eurasia from the early Pleistocene to the beginning of the Holocene and were important herbivores during the Ice Ages. The largest species, Megaloceros giganteus, vernacularly known as the "Irish elk" or "Giant elk", is also the best known. Fallow deer are thought to be their closest living relatives.Megaloceros is part of the deer family which includes moose, elk, reindeer, and other cervids.
Teratornithidae is an extinct family of very large birds of prey that lived in North and South America from the Late Oligocene to Late Pleistocene. They include some of the largest known flying birds.
Leptoptilos is a genus of very large tropical storks, also known as the adjutant bird. The name means thin (lepto) feather (ptilos). Two species are resident breeders in southern Asia, and the marabou stork is found in Sub-Saharan Africa.
Teratornis was a genus of huge North American birds of prey – the best-known of the teratorns - of which, two species are known to have existed: Teratornis merriami and Teratornis woodburnensis. A large number of fossil and subfossil bones, representing more than 100 individuals, have been found in locations in California, Oregon, southern Nevada, Arizona, and Florida, though most are from the Californian La Brea Tar Pits. All remains except one Early Pleistocene partial skeleton from the Leisey Shell Pit near Charlotte Harbor, Florida date from the Late Pleistocene, with the youngest remains dating from the Pleistocene-Holocene boundary.
Pleistocene rewilding is the advocacy of the reintroduction of extant Pleistocene megafauna, or the close ecological equivalents of extinct megafauna. It is an extension of the conservation practice of rewilding, which involves reintroducing species to areas where they became extinct in recent history.
Caracara is a genus in the family Falconidae and the subfamily Polyborinae. It contains one extant species, the crested caracara; and one extinct species, the Guadalupe caracara. The South American Classification Committee of the American Ornithological Society has voted to again merge the two, retaining C. plancus as crested caracara. The taxonomists of the International Ornithologists' Union have also merged them.
Pleistovultur is an extinct genus of large New World vulture from the Late Pleistocene or Early Holocene of South America. The type species P. nevesi was described based in a complete and well preserved right tibiotarsus from the Cuvieri cave deposits in Lagoa Santa region in Minas Gerais state, Brazil. It was larger than Sarcoramphus papa, but smaller than Vultur gryphus.
Emslie's vulture is an extinct species of vulture in the family Cathartidae. It is only known from a series of fossils found in western Cuba. The fossils were primarily found in caves or Quaternary asphault deposits. It is significantly smaller than the extant C. aura. It likely became extinct during the Holocene following the extinction of Cuban Pleistocene megafauna whose bodies it would have fed on, coupled with the loss of the open savannas it would have inhabited.
