Rock Sandpiper
The rock sandpiper (''Calidris ptilocnemis'') is a small shorebird in the sandpiper family Scolopacidae. This is a hardy sandpiper that breeds in the arctic and subarctic regions of Alaska and the Chukotka and Kamchatka Peninsulas. It is closely related to the purple sandpiper that breeds in arctic regions of northeast Canada and the northwest Palearctic. Taxonomy The rock sandpiper was formally described in 1873 by the American ornithologist Elliott Coues and given the binomial name ''Tringa ptilocnemis''. It was formerly placed in the genus ''Erolia'', but is now placed with 23 other sandpipers in the genus ''Calidris'' that was introduced in 1804 by the German naturalist Blasius Merrem. The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The specific epithet ''ptilocnemis'' combines the Ancient Greek ''ptilon'' meaning "feather" with ''knēmē'' meaning "leg". Within the genus ''Calidris'' the r ...

Coues
Elliott Ladd Coues (; September 9, 1842 – December 25, 1899) was an American army surgeon, historian, ornithologist, and author. He led surveys of the Arizona Territory, and later as secretary of the United States Geological and Geographical Survey of the Territories. He founded the American Ornithological Union in 1883, and was editor of its publication, ''The Auk''. Biography Coues was born in Portsmouth, New Hampshire, to Samuel Elliott Coues and Charlotte Haven Ladd Coues. He graduated at Columbian University, Washington, D.C., in 1861, and at the Medical school of that institution in 1863. He served as a medical cadet in Washington in 1862–1863, and in 1864 was appointed assistant-surgeon in the regular army, and assigned to Fort Whipple, Arizona. While there was not yet any legal provision for divorce under its laws, the 1st Arizona State Legislature granted Coues an annulment of his marriage to Sarah A. Richardson. His marriage to Jeannie Augusta McKenney end in d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sister Taxon
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomi ...

Commander Islands
The Commander Islands, Komandorski Islands, or Komandorskie Islands (russian: Командо́рские острова́, ''Komandorskiye ostrova'') are a series of treeless, sparsely populated Russian islands in the Bering Sea located about east of the Kamchatka Peninsula in the Russian Far East. The islands consist of Bering Island ( by ), Medny Island ( by ) and fifteen smaller ones (islets and rocks), the largest of which are ''Tufted Puffin Rock (Kamen Toporkov'' or ''Ostrov Toporkov)'', , and Kamen Ariy, which are between and west of the only settlement, Nikolskoye. Administratively, they compose Aleutsky District of Kamchatka Krai in Russia. Geography The Commander Islands are the westernmost of the Aleutian Islands, most of which are part of the US state of Alaska, and are separated from the closest US island, Attu Island, and the rest of the chain by . Between the two runs the International Date Line. The relief is somewhat diverse, encompassing folded-block mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kuril Islands
The Kuril Islands or Kurile Islands (; rus, Кури́льские острова́, r=Kuril'skiye ostrova, p=kʊˈrʲilʲskʲɪjə ɐstrɐˈva; Japanese: or ) are a volcanic archipelago currently administered as part of Sakhalin Oblast in the Russian Far East. It stretches approximately northeast from Hokkaido in Japan to Kamchatka Peninsula in Russia separating the Sea of Okhotsk from the north Pacific Ocean. There are 56 islands and many minor rocks. The Kuril Islands consist of the Greater Kuril Chain and the Lesser Kuril Chain. They cover an area of around , with a population of roughly 20,000. The islands have been under Russian administration since their 1945 invasion as the Soviet Union towards the end of World War II. Japan claims the four southernmost islands, including two of the three largest ( Iturup and Kunashir), as part of its territory, as well as Shikotan and the Habomai islets, which has led to the ongoing Kuril Islands dispute. The disputed islands are k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ernst Hartert
Ernst Johann Otto Hartert (29 October 1859 – 11 November 1933) was a widely published German ornithologist. Life and career Hartert was born in Hamburg, Germany on 29 October 1859. In July 1891, he married the illustrator Claudia Bernadine Elisabeth Hartert in Frankfurt am Main, Germany, with whom he had a son named Joachim Karl (Charles) Hartert, (1893–1916), who was killed as an English soldier on the Somme. Together with his wife, he was the first to describe the blue-tailed Buffon hummingbird subspecies (''Chalybura buffonii intermedia'' Hartert, E & Hartert, C, 1894). The article ''On a collection of Humming Birds from Ecuador and Mexico'' appears to be their only joint publication. Hartert was employed by Walter Rothschild, 2nd Baron Rothschild as ornithological curator of Rothshild's private Natural History Museum at Tring, in England from 1892 to 1929. Hartert published the quarterly museum periodical ''Novitates Zoologicae'' (1894–39) with Rothschild, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alaskan Peninsula
The Alaska Peninsula (also called Aleut Peninsula or Aleutian Peninsula, ale, Alasxix̂; Sugpiaq: ''Aluuwiq'', ''Al'uwiq'') is a peninsula extending about to the southwest from the mainland of Alaska and ending in the Aleutian Islands. The peninsula separates the Pacific Ocean from Bristol Bay, an arm of the Bering Sea. In literature (especially Russian) the term "Alaska Peninsula" was used to denote the entire northwestern protrusion of the North American continent, or all of what is now the state of Alaska, exclusive of its panhandle and islands. The Lake and Peninsula borough, the Alaskan equivalent of a county, is named after the peninsula. The Alaska/Aleutian Peninsula is also grouped into Southwest Alaska. The other largest peninsulas in Alaska include the Kenai Peninsula and Seward Peninsula. Geography The base of the Alaska Peninsula extends out from the end of the Alaska Range. The Aleutian Range is a highly active volcanic mountain range which runs alon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aleutian Islands
The Aleutian Islands (; ; ale, Unangam Tanangin,”Land of the Aleuts", possibly from Chukchi language, Chukchi ''aliat'', "island"), also called the Aleut Islands or Aleutic Islands and known before 1867 as the Catherine Archipelago, are a chain of 14 large volcanic islands and 55 smaller islands. Most of the Aleutian Islands belong to the U.S. state of Alaska, but some belong to the Russian Federal subjects of Russia, federal subject of Kamchatka Krai. They form part of the Aleutian Arc in the Northern Pacific Ocean, occupying a land area of 6,821 sq mi (17,666 km2) and extending about westward from the Alaska Peninsula toward the Kamchatka Peninsula in Russia, and act as a border between the Bering Sea to the north and the Pacific Ocean to the south. Crossing 180th meridian, longitude 180°, at which point east and west longitude end, the archipelago contains both the westernmost part of the United States by longitude (Amatignak Island) and the easternmost by longitude ( ...

Robert Ridgway
Robert Ridgway (July 2, 1850 – March 25, 1929) was an American ornithologist specializing in systematics. He was appointed in 1880 by Spencer Fullerton Baird, secretary of the Smithsonian Institution, to be the first full-time curator of birds at the United States National Museum, a title he held until his death. In 1883, he helped found the American Ornithologists' Union, where he served as officer and journal editor. Ridgway was an outstanding descriptive taxonomist, capping his life work with ''The Birds of North and Middle America'' (eight volumes, 1901–1919). In his lifetime, he was unmatched in the number of North American bird species that he described for science. As technical illustrator, Ridgway used his own paintings and outline drawings to complement his writing. He also published two books that systematized color names for describing birds, ''A Nomenclature of Colors for Naturalists'' (1886) and ''Color Standards and Color Nomenclature'' (1912).

Hall Island (Alaska)
Hall Island (russian: Холл) is a small island located to the northwest of St. Matthew Island in the Bering Sea in Alaska, United States. It serves as a haulout site for Pacific walrus. It is in length and has a land area of . The highest point is . Hall Island is uninhabited. It is part of the Bering Sea unit of the Alaska Maritime National Wildlife Refuge. It is one of three hall islands. History Early Russian hunters knew this island as "Ostrov Morzhovoy" ('Walrus Island') (Tevenkov, 1852, mpa 20). The Imperial Russian Hydrographic Department Chart 1427 called it "Ostrov Sindsha" probably for Lt. Sind, its alleged discoverer, in 1764. Commodore Joseph Billings of the Imperial Russian Navy and Lt. Gavril Sarychev anchored between this island and St. Matthew on July 14, 1791 (O.S.). Since 1875, this island has been called "Hall" on American maps, presumably for Lt. Robert Hall, who was with Captain Billings, or also for Cape Hall. Gallery Hall Island, Bering Sea.jpg, ...

Pribilof Islands
The Pribilof Islands (formerly the Northern Fur Seal Islands; ale, Amiq, russian: Острова Прибылова, Ostrova Pribylova) are a group of four volcanic islands off the coast of mainland Alaska, in the Bering Sea, about north of Unalaska and 200 miles (320 km) southwest of Cape Newenham. The Siberian coast is roughly northwest. About in total area, they are mostly rocky and are covered with tundra, with a population of 572 as of the 2010 census. Principal islands The principal islands are Saint Paul and Saint George. The former was named for the Feast of Saints Peter and Paul, on the day of which the island was first encountered by the Russian explorer Gavriil Pribylov; the latter was probably named for the ship sailed by Pribylov. The Otter and Walrus islets are near St. Paul. The total land area of all the islands is . The islands are part of the Bering Sea unit of the Alaska Maritime National Wildlife Refuge.
