Puffin Island (Alaska)
Puffin Island ( Iñupiaq: ''Aġviat'') is a rocky islet in the Kotzebue Sound, Alaska. It is located off Spafarief Bay at the mouth of Eschscholtz Bay, just south of the Choris Peninsula, in the Northwest Arctic Borough at . This island is located NW of Chamisso Island, . SW of Selawik, Kotzebue-Kobuk Low. Puffin Island is a steep rock and, though much smaller than Chamisso Island, it has many more nesting birds on its surface, especially horned puffins, black-legged kittiwakes, and thick-billed murres which build their nests on the steep-walled cliffs that fall into Spafarief Bay. Iñupiat cross from the mainland to gather eggs, primarily from kittiwakes and murres. With the exception of birds and the occasional fox that crosses frozen sea in winter, nothing lives on the islands. Walruses, seals, and whales can often be seen in Spafarief Bay.

Chamisso Island
Chamisso Island ( Iñupiaq: ''Iguaġvik'') is a small island in Kotzebue Sound, Alaska. It is located off Spafarief Bay at the mouth of Eschscholtz Bay, just south of the Choris Peninsula. The island is roughly triangular. It is long and an wide. The highest point on Chamisso Island is above sea level. It comprises one large sand spit and a low beach zone surrounding a covering of tundra with a few marshy bogs. Although Chamisso Island is much larger, nearby Puffin Island houses many more nesting birds, especially horned puffins, black-legged kittiwakes, and thick-billed murres which build their nests on the steep-walled cliffs that fall into Spafarief Bay. Iñupiat cross from the mainland to gather eggs, primarily from kittiwakes and murres.

Kittiwake
The kittiwakes (genus ''Rissa'') are two closely related seabird species in the gull family Laridae, the black-legged kittiwake (''Rissa tridactyla'') and the red-legged kittiwake (''Rissa brevirostris''). 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. 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. Description The two species are physically very similar. They have a white head and body, grey back, grey wings tipped solid black and a bright yellow bill. Black-legged kittiwake adults are somewhat larger (roughly in length with a wingspan of ) than red-legged kittiwakes ( in length with a wingspan around ). Other differences include a shorter bill, larger eyes, a larger, rounder head ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seabird Colonies
Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, while modern seabird families emerged in the Paleogene. Seabirds generally live longer, breed later and have fewer young than other birds, but they invest a great deal of time in their young. Most species nest in colonies, varying in size from a few dozen birds to millions. Many species are famous for undertaking long annual migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even on each other. Seabirds can be highly pelagic, coastal, or in some cases spend a part of the year away from the sea entirely. Seabirds and humans have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alaska Maritime National Wildlife Refuge
The Alaska Maritime National Wildlife Refuge (often shortened to Alaska Maritime or AMNWR) is a United States National Wildlife Refuge comprising 2,400 islands, headlands, rocks, islets, spires and reefs in Alaska, with a total area of , of which is wilderness. The refuge stretches from Cape Lisburne on the Chukchi Sea to the tip of the Aleutian Islands in the west and Forrester Island in the southern Alaska Panhandle region in the east. The refuge has diverse landforms and terrains, including tundra, rainforest, cliffs, volcanoes, beaches, lakes, and streams. Alaska Maritime National Wildlife Refuge is well known for its abundance of seabirds. About 75 percent of Alaskan native marine birds, 15 to 30 million among 55 species, use the refuge. AMNWR also provides a nesting habitat for an estimated 40 million seabirds, representing 80 percent of all seabirds in North America. The birds congregate in "bird cities" (colonies) along the coast. Each species has a specialized nesti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whales
Whales are a widely distributed and diverse group of fully Aquatic animal, aquatic placental mammal, placental marine mammals. As an informal and Colloquialism, colloquial grouping, they correspond to large members of the infraorder Cetacea, i.e. all cetaceans apart from dolphins and porpoises. Dolphins and porpoises may be considered whales from a formal, Cladistics, cladistic perspective. Whales, dolphins and porpoises belong to the order Cetartiodactyla, which consists of even-toed ungulates. Their closest non-cetacean living relatives are the hippopotamuses, from which they and other cetaceans diverged about 54 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have had their Most recent common ancestor, last common ancestor around 34 million years ago. Mysticetes include four Neontology, extant (living) Family (biology), families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriid ...

Pinniped
Pinnipeds (pronounced ), commonly known as seals, are a widely range (biology), distributed and diverse clade of carnivorous, fin-footed, semiaquatic, mostly marine mammals. They comprise the extant taxon, extant families Odobenidae (whose only living member is the walrus), Otariidae (the eared seals: sea lions and fur seals), and Phocidae (the earless seals, or true seals), with 34 extant species and more than 50 extinct species described from fossils. While seals were historically thought to have descended from two ancestral lines, molecular phylogenetics, molecular evidence supports them as a monophyletic group (descended from one ancestor). Pinnipeds belong to the suborder Caniformia of the order Carnivora; their closest living relatives are musteloids (Mustelidae, weasels, Procyonidae, raccoons, skunks and red pandas), having diverged about 50 million years ago. Seals range in size from the and Baikal seal to the and southern elephant seal. Several species exhibit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walruses
The walrus (''Odobenus rosmarus'') is a large pinniped marine mammal with discontinuous distribution about the North Pole in the Arctic Ocean and subarctic seas of the Northern Hemisphere. It is the only extant species in the family Odobenidae and genus ''Odobenus''. This species is subdivided into two subspecies: the Atlantic walrus (''O. r. rosmarus''), which lives in the Atlantic Ocean, and the Pacific walrus (''O. r. divergens''), which lives in the Pacific Ocean. Adult walrus are characterised by prominent tusks and whiskers, and considerable bulk: adult males in the Pacific can weigh more than and, among pinnipeds, are exceeded in size only by the two species of elephant seals. Walrus live mostly in shallow waters above the continental shelves, spending significant amounts of their lives on the sea ice looking for benthic bivalve molluscs. Walruses are relatively long-lived, social animals, and are considered to be a "keystone species" in the Arctic marine regions. The ...

Murre
''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. Taxonomy The genus ''Uria'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the common murre (''Uria aalge'') as the type species. The genus name is from Ancient Greek ''ouria'', a waterbird mentioned by Athenaeus. 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. ''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, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
