Bird cliff at Orkney Islands

Bird cliffs, or nesting cliffs, are steep cliffs with numerous small shelves which serve as nesting locations for bird colonies. Bird cliffs are found on islands in the North Atlantic and Arctic, such as the Faroe Islands, Iceland, the Svalbard archipelago and on islands off Northern Norway. Among species that nest in large numbers on bird cliffs are common murre, thick-billed murre, razorbill, kittiwake, little auk and Atlantic puffin. The number of breeding couples may exhibit large variations depending on available food. Bird cliffs have often been exploited as a food resource by the local population, as well as being used by hunters and egg collectors. [1]

Kittiwake Genus of birds

The kittiwakes are two closely related seabird species in the gull family Laridae, the black-legged kittiwake and the red-legged kittiwake. The epithets "black-legged" and "red-legged" are used to distinguish the two species in North America, but in Europe, where Rissa brevirostris is not found, the black-legged kittiwake is often known simply as kittiwake, or more colloquially in some areas as tickleass or tickleace. The name is derived from its call, a shrill 'kittee-wa-aaake, kitte-wa-aaake'. The genus name Rissa is from the Icelandic name Rita for the black-legged kittiwake.

Puffin One of several species of seabird

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.

Auk Family of birds

An auk or alcid is a bird of the family Alcidae in the order Charadriiformes. The alcid family includes the murres, guillemots, auklets, puffins, and murrelets. The word auk is derived from Icelandic álka, from Old Norse alka (“auk”), from Proto-Germanic *alkǭ.

Atlantic puffin Species of seabird (Fratercula arctica)

The Atlantic puffin, also known as the common puffin, is a species of seabird in the auk family. It is the only puffin native to the Atlantic Ocean; two related species, the tufted puffin and the horned puffin, are found in the northeastern Pacific. The Atlantic puffin breeds in Québec, Iceland, Norway, Greenland, Newfoundland and Labrador, Nova Scotia and the Faroe Islands, and as far south as Maine in the west and France in the east. The Atlantic Puffin is most commonly found on the Westman Islands, Iceland. Although it has a large population and a wide range, the species has declined rapidly, at least in parts of its range, resulting in it being rated as vulnerable by the IUCN. On land, it has the typical upright stance of an auk. At sea, it swims on the surface and feeds mainly on small fish, which it catches by diving under water, using its wings for propulsion.

Razorbill Species of seabird

The razorbill, razor-billed auk, or lesser auk is a colonial seabird in the monotypic genus Alca of the family Alcidae, the auks. It is the closest living relative of the extinct great auk. Wild populations live in the subarctic waters of the Atlantic Ocean.

Common murre Species of bird

The common murre or common guillemot is a large auk. It is also known as the thin-billed murre in North America. 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.

Thick-billed murre Species of bird

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. The genus name is from Ancient Greek ouria, a waterbird mentioned by Athenaeus. The species term lomvia is a Swedish word for an auk or diver. The English "guillemot" is from French guillemot probably derived from Guillaume, "William". "Murre" is of uncertain origins, but may imitate the call of the common guillemot.

Black-legged kittiwake Species of bird

The black-legged kittiwake is a seabird species in the gull family Laridae.

Mykines, Faroe Islands Island in Faroe Islands, Kingdom of Denmark

Mykines is the westernmost of the 18 main islands of the Faroese Archipelago.

Viðoy Island in Faroe Islands, Kingdom of Denmark

Viðoy is the northernmost island in the Faroe Islands, located east of Borðoy to which it is linked via a causeway. The name means wood island, despite the fact that no trees grow on the island; the name relates to the driftwood that floats in from Siberia and North America.

Baccalieu Island

Baccalieu Island or Bacalhoo Island is a 5 km2 uninhabited island at the northern extremities of Conception Bay in Subdivision 1G, near the community of Red Head Cove, Newfoundland and Labrador, Canada. It is separated from the island of Newfoundland by Baccalieu Tickle, a small strait and an abundant fishing ground. The island has some trees but mostly rocky.

Funk Island

Funk Island is a small, barren, isolated, uninhabited island approximately 60 kilometres (37 mi) northeast of Wesleyville, New-Wes-Valley, Newfoundland and Labrador, Canada.

Prince Leopold Island

Prince Leopold Island is an island in the Qikiqtaaluk Region of Nunavut, Canada. It is located in Lancaster Sound at the junction of Prince Regent Inlet and Barrow Strait. Somerset Island is situated 13 km (8.1 mi) to the southwest; Port Leopold, an abandoned trading post, is the closest landmark. The island is significant as a summer habitat and breeding ground for large populations of several arctic bird species.

Chamisso Wilderness

Chamisso Wilderness is a 455-acre (184 ha) wilderness area in the U.S. state of Alaska. It was designated by the United States Congress in 1975.

Fowlsheugh

Fowlsheugh is a coastal nature reserve in Kincardineshire, northeast Scotland, known for its 70-metre-high (230 ft) cliff formations and habitat supporting prolific seabird nesting colonies. Designated as a Site of Special Scientific Interest (SSSI) by Scottish Natural Heritage, the property is owned by the Royal Society for the Protection of Birds. Fowlsheugh can be accessed by a public clifftop trail, or by boats which usually emanate from the nearby harbour at the town of Stonehaven. Tens of thousands of pelagic birds return to the site every spring to breed, after wintering at sea or in more southern climates, principal species being puffins, razorbills, kittiwakes, fulmars and guillemots.

Witless Bay Ecological Reserve

Witless Bay Ecological Reserve is an ecological preserve close to St. John's, Newfoundland and Labrador, Canada. The Witless Bay Ecological Reserve consists of four islands: Gull Island, Green Island, Great Island, and Pee Pee Island. Immense numbers of birds nest on these islands during the seabird breeding season, roughly from 1 April through 1 September.

Bird colony

A bird colony is a large congregation of individuals of one or more species of bird that nest or roost in proximity at a particular location. Many kinds of birds are known to congregate in groups of varying size; a congregation of nesting birds is called a breeding colony. Colonial nesting birds include seabirds such as auks and albatrosses; wetland species such as herons; and a few passerines such as weaverbirds, certain blackbirds, and some swallows. A group of birds congregating for rest is called a communal roost. Evidence of colonial nesting has been found in non-neornithine birds (Enantiornithes), in sediments from the Late Cretaceous (Maastrichtian) of Romania.

Baccalieu Island Ecological Reserve is a wildlife reserve located on an island off the northeastern tip of Bay de Verde Peninsula of Newfoundland.

Runde Ramsar Site

The Runde Ramsar Site is a Ramsar Convention area consisting of five previously approved protected areas in the municipalities of Herøy and Ulstein in Møre og Romsdal county, Norway. The area was established in 2013.
