The taiga bean goose is a species of goose that breeds in northern Europe and Asia. It is migratory and winters further south in Europe and Asia. This and the tundra bean goose were recognised as separate species by the International Ornithologists' Union and the American Ornithological Society from 2007, but are still considered a single species by some other authorities, notably BirdLife International and the IUCN. The taiga and tundra bean goose diverged about 2.5 million years ago and established secondary contact c. 60,000 years ago, resulting in extensive gene flow.
The lesser white-fronted goose is a goose closely related to the larger greater white-fronted goose. It breeds in the northernmost Palearctic, but it is a scarce breeder in Europe, with a reintroduction attempt in Fennoscandia.
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 southerly 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.
Anas is a genus of dabbling ducks. It includes the pintails, most teals, and the mallard and its close relatives. It formerly included additional species but following the publication of a molecular phylogenetic study in 2009 the genus was split into four separate genera. The genus now contains 31 living species. The name Anas is the Latin for "duck".
Mergellus is a genus of duck. The smew (Mergellus albellus) is the only living species, but an extinct species known as Mergellus mochanovi has also been described from Late Pleistocene deposits in the Yakutia region of Russia.
The woolly rhinoceros is an extinct species of rhinoceros that inhabited northern Eurasia during the Pleistocene epoch. The woolly rhinoceros was a member of the Pleistocene megafauna. The woolly rhinoceros was large, comparable in size to the largest living rhinoceros species, the white rhinoceros, and covered with long, thick hair that allowed it to survive in the extremely cold, harsh mammoth steppe. It had a massive hump reaching from its shoulder and fed mainly on herbaceous plants that grew in the steppe. Mummified carcasses preserved in permafrost and many bone remains of woolly rhinoceroses have been found. Images of woolly rhinoceroses are found among cave paintings in Europe and Asia, and evidence has been found suggesting that the species was hunted by humans. The range of the woolly rhinoceros contracted towards Siberia beginning around 17,000 years ago, with the youngest known records being around 14,000 years old in northeast Siberia, coinciding with the Bølling–Allerød warming, which likely disrupted its habitat, with environmental DNA records possibly extending the range of the species around 9,800 years ago. Its closest living relative is the Sumatran rhinoceros.
Panthera spelaea, commonly known as the cave lion, is an extinct Panthera species that was native to Eurasia and northwest North America during the Pleistocene epoch. Genetic analysis of ancient DNA has revealed that while closely related, it was a distinct species genetically isolated from the modern lion, with the genetic divergence between the two species estimated at around 500,000 years ago. The earliest fossils of the P. spelaea lineage in Eurasia date to around 700,000 years ago. It is closely related and probably ancestral to the American lion. The species ranged from Western Europe to eastern Beringia in North America, and was a prominent member of the mammoth steppe fauna, and an important apex predator across its range. It became extinct about 13,000 years ago. It closely resembled living lions with a coat of yellowish-grey fur though unlike extant lions, males appear to have lacked manes.
Anser is a waterfowl genus that includes the grey geese and the white geese. It belongs to the true goose and swan subfamily of Anserinae under the family of Anatidae. The genus has a Holarctic distribution, with at least one species breeding in any open, wet habitats in the subarctic and cool temperate regions of the Northern Hemisphere in summer. Some also breed farther south, reaching into warm temperate regions. They mostly migrate south in winter, typically to regions in the temperate zone between the January 0 °C (32 °F) and 5 °C (41 °F) isotherms.
Stephanorhinus kirchbergensis, also known as Merck's rhinoceros is an extinct species of rhinoceros belonging to the genus Stephanorhinus from the Early-Middle to Late Pleistocene of Eurasia. Its range spanned from Western Europe to Eastern Asia. Among the last members of the genus, it co-existed alongside Stephanorhinus hemitoechus in the western part of its range.
Yevgeny Nikolayevich Kurochkin was a Russian paleornithologist at the Paleontological Institute of the Russian Academy of Sciences. He served as President of the Menzbier Ornithological Society.
The bean goose is a species complex of goose that breeds in northern Europe and Eurosiberia. It has at least two distinct varieties, one inhabiting taiga habitats and one inhabiting tundra. These are recognised as separate species by the American Ornithologists' Union and the IOC, but are considered a single species by other authorities, such as the British Ornithologists' Union. The related pink-footed goose has also been included in the species complex. It is migratory and winters further south in Europe and Asia.
Podiceps solidus is an extinct small species of Upper Miocene to Lower Pliocene grebe from Western Mongolia.
Pterocles bosporanus is an extinct species of sandgrouse, described in 2023 from early Pleistocene-aged fossil material found in central Crimea. Potential additional remains are known from Italy. The only confirmed specimen is part of a limb bone, and the species is larger than other members of the genus Pterocles.
Heteroanser is an extinct genus of geese, which lived during the Late Miocene in what is today Western Mongolia. Its remains were discovered in the upper subformation of the Hyargas Nuur Formation, on the northern shore of the Khyargas Nuur, in Uvs Province. This genus is known from a single and incomplete tarsometatarsus, which differs significantly from all other Neogene genera of anatinae.
Chauvireria is an extinct genus of small-sized landfowl, belonging to the family Phasianidae, and closely related to modern partridges, Old World quails and francolins. Two species are known from the genus : C. balcanica, the type species, and C. bulgarica. Both species lived in what is today Western Bulgaria during the Early Pleistocene.
Bambusicola wenzensis is an extinct species of Bambusicola known to have inhabited Poland during the Pliocene epoch.
Coturnix augustus is an extinct species of Coturnix that lived in Mongolia during the Pliocene epoch.
Mergellus mochanovi is an extinct species of Mergellus that lived in Russia during the Late Pleistocene.
