Uria is a genus of seabirds in the auk family known in Europe as guillemots , in most of North America as murres, and in Newfoundland and Labrador as turr. These are medium-sized birds with mainly brown or black plumage in the breeding season. They breed on the coasts of the northern Atlantic and Pacific oceans.
The genus Uria was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the common murre (Uria aalge) as the type species. [1] [2] The genus name is from Ancient Greek ouria, a waterbird mentioned by Athenaeus. [3] The English "guillemot" is from French guillemot probably derived from Guillaume, "William". [4] "Murre" is of uncertain origins, but may imitate the call of the common guillemot. [5]
Uria auks are relatives of the razorbill, little auk and the extinct great auk and together make up the tribe Alcini. Despite the similar British common names, they are not so closely related to the Cepphus guillemots, which form the tribe Cepphini.
The genus contains two species: [6]

Some prehistoric Uria species are also known:
Uria brodkorbi is interesting insofar as it is the only known occurrence of the Alcini tribe in the temperate to subtropical Pacific, except for the very fringe of the range of U. aalge. It suggests that the Uria species, which are the sister taxon to all the other Alcini, and like them are usually believed to have evolved in the Atlantic, may have evolved in the Caribbean or possibly close to the Isthmus of Panama. The modern Pacific distribution would then be part of a later arctic expansion, whereas most other auk lineages form clades with a continuous range in the Pacific, from arctic to subtropical waters.
These birds breed in large colonies on coastal cliffs, laying single elongated conical eggs directly on cliff ledges. They move south in winter to keep in ice-free waters.
They dive for food from the surface, swimming underwater and being among the deepest divers of all birds, using their stubby wings to routinely dive to more than 100 meters, and feeding on fish and crustaceans, also some molluscs, insects and plant material. [7]
Adult birds are black or brown on the head, neck, back and wings with white underparts. The bill is long and pointed. They have a small rounded black tail. The lower face becomes white in winter.
The flight is strong and direct, and these species have fast wing beats due to the short wings.
Uria guillemots produce a variety of harsh cackling calls at the breeding colonies, but are silent at sea.
Puffins are any of three species of small alcids (auks) in the bird genus Fratercula. These are pelagic seabirds that feed primarily by diving in the water. They breed in large colonies on coastal cliffs or offshore islands, nesting in crevices among rocks or in burrows in the soil. Two species, the tufted puffin and horned puffin, are found in the North Pacific Ocean, while the Atlantic puffin is found in the North Atlantic Ocean.
Auks or alcids are a group of birds of the family Alcidae in the order Charadriiformes. The alcid family includes the murres, guillemots, auklets, puffins, and murrelets. The family contains 25 extant or recently extinct species that are divided into 11 genera. Auks are found throughout the Northern Hemisphere.
A phalarope is any of three living species of slender-necked shorebirds in the genus Phalaropus of the bird family Scolopacidae.
Guillemot is the common name for several species of seabird in the Alcidae or auk family, part of the order Charadriiformes. In Europe, the term covers two genera, Uria and Cepphus. In North America the Uria species are called murres and only the Cepphus species are called "guillemots".
The skuas are a group of predatory seabirds with seven species forming the genus Stercorarius, the only genus in the family Stercorariidae. The three smaller skuas, the Arctic skua, the long-tailed skua, and the pomarine skua, are called jaegers in North American English.
A booby is a seabird in the genus Sula, part of the family Sulidae. Boobies are closely related to the gannets (Morus), which were formerly included in Sula.
The razorbill is a North Atlantic colonial seabird and the only extant member of the genus Alca of the family Alcidae, the auks. It is the closest living relative of the extinct great auk. Historically, it has also been known as "auk", "razor-billed auk" and "lesser auk".
The common murre or common guillemot is a large auk. It has a circumpolar distribution, occurring in low-Arctic and boreal waters in the North Atlantic and North Pacific. It spends most of its time at sea, only coming to land to breed on rocky cliff shores or islands.
The little auk (Europe) or dovekieAlle alle is a small auk, the only member of the genus Alle. Alle is the Sami name of the long-tailed duck; it is onomatopoeic and imitates the call of the drake duck. Linnaeus was not particularly familiar with the winter plumages of either the auk or the duck, and appears to have confused the two species. Other old names include rotch, rotche, bullbird, and sea dove, although the latter sometimes refers to a relative, the black guillemot.
The thick-billed murre or Brünnich's guillemot is a bird in the auk family (Alcidae). This bird is named after the Danish zoologist Morten Thrane Brünnich. The very deeply black North Pacific subspecies Uria lomvia arra is also called Pallas' murre after its describer.
Puffinus is a genus of seabirds in the order Procellariiformes that contains about 20 small to medium-sized shearwaters. Two other shearwater genera are named: Calonectris, which comprises three or four large shearwaters, and Ardenna with another seven species.
Cepphus is a genus of seabirds in the auk family also referred to as true guillemots or, in North America, simply as guillemots. The genus name Cepphus is from Ancient Greek κέπφος kepphos, a pale waterbird mentioned by Greek authors including Aristotle. The English word "guillemot" is from French guillemot probably derived from Guillaume, "William". "Murre" is of uncertain origins but may imitate the call of the common guillemot.
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.
Grus is a genus of large birds in the crane family.
Lagopus is a genus of birds in the grouse subfamily commonly known as ptarmigans. The genus contains four living species with numerous described subspecies, all living in tundra or cold upland areas.
Porphyrio is the swamphen or swamp hen bird genus in the rail family. It includes some smaller species of gallinules which are sometimes separated as genus Porphyrula or united with the gallinules proper in Gallinula. The Porphyrio gallinules are distributed in the warmer regions of the world. The group probably originated in Africa in the Middle Miocene, before spreading across the world in waves from the Late Miocene to Pleistocene.
Ciconia is a genus of birds in the stork family. Six of the seven living species occur in the Old World, but the maguari stork has a South American range. In addition, fossils suggest that Ciconia storks were somewhat more common in the tropical Americas in prehistoric times.
Brachyramphus is a small genus of seabirds from the North Pacific. Brachyramphus is from Ancient Greek brakhus, "short", and rhamphos, "bill". In English the species are named as "murrelets"; this is a diminutive of "murre", a word of uncertain origins, but which may imitate the call of the common guillemot.
Synthliboramphus is a small genus of seabirds in the auk family from the North Pacific. The genus name Synthliboramphus is from Ancient Greek sunthlibo, "to compress", and rhamphos, "bill". The English name "Murrelet" is a diminutive of "murre", a word of uncertain origins, but which may imitate the call of the common guillemot.
