Black-vented Shearwater
The black-vented shearwater (''Puffinus opisthomelas'') is a species of seabird endemic to islands off of the Pacific coast of Mexico and the Gulf of California. It is a smaller shearwater, with a length of 30–38 cm, 76–89 cm wingspan and a mass of around 400 g. This species is pelagic and feeds mainly on small fish. It is Nocturnality, nocturnal, and is most active in low light settings. Taxonomy and Origins The name "puffin" is thought to originate from the Middle English term "pophyn," which was used in the Middle Ages to describe the fatty, preserved young shearwaters that were prepared as food. Since shearwaters and Atlantic puffins (''Fratercula arctica'') often nest in close proximity, the name 'puffin' was mistakenly applied to the Atlantic puffin. Over time, the name stuck, and today it is used for the Atlantic puffin species. The name "puffin" also remained associated with the shearwaters and the genus ''Puffinus.'' The black-vented shearwater is one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elliott 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 en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of Genus, genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical o ...

Islas San Benito
The Islas San Benito lie in the Pacific Ocean off the west coast of the Mexican state of Baja California, 25 km west of Cedros Island. They are part of the Cedros Island ''delegación'', a subdivision of Ensenada (municipality), Baja California.

Isla De Guadalupe
Guadalupe Island () is a volcanic island located off the western coast of Mexico's Baja California peninsula and about southwest of the city of Ensenada in the state of Baja California, in the Pacific Ocean. The various volcanoes are extinct or dormant. In 2005 Guadalupe Island and its surrounding waters and islets were declared a biosphere reserve to restore its vegetation (decimated by feral goats) and to protect its population of marine mammals and birds. The island was a popular destination for great white shark cage diving before a tourism ban was put in place in 2022. Guadalupe Island is inhabited only by scientists, military personnel operating a weather station, and a small group of seasonal fishermen. The island is mostly arid and has very little surface water. The two other Mexican island groups in the Pacific Ocean that are not on the continental shelf are the Revillagigedo Islands and Rocas Alijos.

San Quintín, Baja California
is a city in San Quintín Municipality, Baja California, located on the Pacific Coast of Mexico. The city had a population of 4777 in 2011. San Quintín is an important agricultural center for Baja California. History In the early 1800s the sea otters of San Quintín Bay were targeted by a series of joint ventures between American maritime fur traders and the Russian–American Company (RAC). The first such venture involved the Boston-based maritime fur trading merchant ship ''O'Cain''. RAC Chief Manager Alexander Baranov supplied ''O'Cain'' with twenty baidarkas (Aleutian kayaks) and about forty indigenous Alaskan sea otter hunters, plus two overseers to manage the hunters and hunting, Afanasii Shvetsov and Timofei Tarakanov. ''O'Cain'' sailed to San Quintín Bay and stayed for over three months while Tarakanov and Shvetsov led indigenous sea otter hunting parties all along the coast between Mission Rosario and Misión Santo Domingo de la Frontera.

Shearwater
Shearwaters are medium-sized long-winged seabirds in the petrel family Procellariidae. They have a global marine distribution, but are most common in temperate and cold waters, and are pelagic outside the breeding season. Description These tubenose birds fly with stiff wings and use a "shearing" flight technique (flying very close to the water and seemingly cutting or "shearing" the tips of waves) to move across wave fronts with the minimum of active flight. This technique gives the group its English name. Some small species like the Manx shearwater are cruciform in flight, with their long wings held directly out from their bodies. Behaviour Movements Many shearwaters are long-distance migrants, perhaps most spectacularly sooty shearwaters, which cover distances in excess of from their breeding colonies on the Falkland Islands (52°S 60°W) to as far as 70° north latitude in the North Atlantic Ocean off northern Norway, and around New Zealand to as far as 60° north latitude i ...

The Pacific Ocean is the largest and deepest of Earth's five Borders of the oceans, oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean, or, depending on the definition, to Antarctica in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east.
