Nyctibius Jamaicensis
The northern potoo (''Nyctibius jamaicensis'') is a nocturnal bird belonging to the potoo family, Nyctibiidae. It is found from Mexico south to Costa Rica, and on the islands of Jamaica and Hispaniola (in the Dominican Republic and Haiti). It was formerly classified as a subspecies of the common potoo (''Nyctibius griseus'') but is now usually treated as a separate species based on differences in vocalizations. Taxonomy The northern potoo was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with all the nightjar like species in the genus ''Caprimulgus'' and coined the binomial name ''Caprimulgus jamaicensis''. Gmelin based his description on earlier accounts of the bird in Jamaica, including Hans Sloane's "Wood owle" published in 1725 and John Latham's "Jamaican goatsucker" published in 1783. The northern potoo is now one of the seven potoos placed in the genus '' ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Hans Sloane
Sir Hans Sloane, 1st Baronet (16 April 1660 – 11 January 1753), was an Irish physician, naturalist, and collector, with a collection of 71,000 items which he bequeathed to the British nation, thus providing the foundation of the British Museum, the British Library, and the Natural History Museum, London. He was elected to the Royal Society at the age of 24. Sloane travelled to the Caribbean in 1687 and documented his travels and findings with extensive publications years later. Sloane was a renowned medical doctor among the aristocracy, and was elected to the Royal College of Physicians at age 27. Though he is credited with the invention of chocolate milk, it is more likely that he learned the practice of adding milk to drinking chocolate while living and working in Jamaica. Streets and places were later named after him, including Hans Place, Hans Crescent, and Sloane Square in and around Chelsea, London – the area of his final residence – and also Sir Hans Sloane Square ...

Iris (anatomy)
In humans and most mammals and birds, the iris (plural: ''irides'' or ''irises'') is a thin, annular structure in the eye, responsible for controlling the diameter and size of the pupil, and thus the amount of light reaching the retina. Eye color is defined by the iris. In optical terms, the pupil is the eye's aperture, while the iris is the diaphragm. Structure The iris consists of two layers: the front pigmented fibrovascular layer known as a stroma and, beneath the stroma, pigmented epithelial cells. The stroma is connected to a sphincter muscle (sphincter pupillae), which contracts the pupil in a circular motion, and a set of dilator muscles ( dilator pupillae), which pull the iris radially to enlarge the pupil, pulling it in folds. The sphincter pupillae is the opposing muscle of the dilator pupillae. The pupil's diameter, and thus the inner border of the iris, changes size when constricting or dilating. The outer border of the iris does not change size. The constricti ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Plumage
Plumage ( "feather") is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morphs. The placement of feathers on a bird is not haphazard, but rather emerge in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month or so l ...

Gonâve Island
Gonâve Island or Zile Lagonav (french: Île de la Gonâve, ; also ''La Gonâve'') is an island of Haiti located west-northwest of Port-au-Prince in the Gulf of Gonâve. It is the largest of the Hispaniolan satellite islands. The island is an arrondissement (''Arrondissement de La Gonâve'') or Ouest-Insulaire in the Ouest and includes the communes of Anse-à-Galets and Pointe-à-Raquette. Etymology La Gonave or Gonave is a Frenchify form of Guanabo. History Taino Period The indigenous Taínos called the island ''Guanabo.'' Under the leadership of Hatuey, the island was the last refuge of the natives after the invasion of the Europeans. European Period No major French or Spanish settlement was built in La Gonave. During the colonial period, the island was uninhabited by colonists, which led the indigenous Taínos to seek refuge there after early battles with the Spanish. Runaway slaves in the French period, too, sometimes sought out the island for a place to hide from their o ...

Charles Wallace Richmond
Charles Wallace Richmond (December 31, 1868 – May 19, 1932) was an American ornithologist. He is best remembered for a compilation of the Latin names of birds that is called the Richmond Index. Life and work He was born in Kenosha, Wisconsin and was the eldest son of Edward Leslie and Josephine Ellen Richmond. His mother died when he was 12. His father who was a railway mail clerk moved to Washington, D.C. and joined the Government Printing House there.

Nominate Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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).

Edward William Nelson
Edward William Nelson (May 8, 1855 – May 19, 1934) was an American naturalist and ethnologist. A collector of specimens and field naturalist of repute, he became a member of several expeditions to survey the fauna and flora. He was part of a team with Clinton Hart Merriam that took part in the Death Valley Expedition. He also explored the Yosemite Valley. A number of vertebrate species are named after him. Biography Nelson was born in Manchester, New Hampshire, on May 8, 1855, the first son of William and Martha () Nelson. Nelson and his brother then lived with his maternal grandparents in the Adirondacks when his father joined the Union Army and mother went to Baltimore as a nurse. Here he fell in love with the wilderness. Nelson moved to Chicago after his father was killed in the Civil War and his mother established a dressmaking business. In 1871, his large insect collection was lost in the Chicago Fire and the family was left homeless. This was the time that h ...

Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
