Yunnan Nuthatch
The Yunnan nuthatch (''Sitta yunnanensis'') is a bird species in the nuthatch family Sittidae. It was first described by William Robert Ogilvie-Grant in 1900 based on a male holotype. It is a small nuthatch, measuring in length on average and weighs between . The grey-blue upperparts contrast with the light, smooth, buffy lowerparts. It has a fine white eyebrow above a black eyestripe, which is distinct when the plumage is fresh, and exhibits a small degree of sexual dimorphism. A noisy bird, it produces simple, nasal sounds, sometimes in repetitive series. Its ecology is not well-known, but it feeds on insects that it finds on pine branches. It can be found in the prefectures of Yunnan, Sichuan, and Guizhou in Southwest China, where it prefers sparsely forested pine forests and avoids dense spruce and fir forests. It is listed as a near-threatened species on the IUCN Red List and it is generally rare but can be locally common. It has a small range of . A 2009 study predicted t ...

Black Dragon Pool
Black Dragon Pool () is a famous pond in the scenic Jade Spring Park (Yu Quan Gong Yuan) located at the foot of Elephant Hill, a short walk north of the Old Town of Lijiang in Yunnan province, China. It was built in 1737 during the Qing dynasty and offers views of the region's tallest mountain, Jade Dragon Snow Mountain, over its white marble bridge. In the past, the pool itself has sometimes been dry, spoiling the famous view. In 2010, however, the park was declared a water conservation area by the local government. As of 2014, the pool stands full of water, its former beauty restored. The park features several smaller temples and pavilions: *The Moon-Embracing Pavilion (), originally built in the late Ming dynasty. The current structure is a reproduction from 1963 after a fire in 1950. *The Longshen Temple (), also known as Dragon God Temple, was constructed by local Naxi people in 1737 and is located to the east of the park. It was given the name Dragon God of Jade Spring b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Captain
Captain is a title, an appellative for the commanding officer of a military unit; the supreme leader of a navy ship, merchant ship, aeroplane, spacecraft, or other vessel; or the commander of a port, fire or police department, election precinct, etc. In militaries, the captain is typically at the level of an officer commanding a company or battalion of infantry, a ship, or a battery of artillery, or another distinct unit. The term also may be used as an informal or honorary title for persons in similar commanding roles. Etymology The term "captain" derives from (, , or 'the topmost'), which was used as title for a senior Byzantine military rank and office. The word was Latinized as capetanus/catepan, and its meaning seems to have merged with that of the late Latin "capitaneus" (which derives from the classical Latin word "caput", meaning head). This hybridized term gave rise to the English language term captain and its equivalents in other languages (, , , , , , , , , kapitány, K ...

Ibis (journal)
''Ibis'' (formerly ''The Ibis''), subtitled ''the International Journal of Avian Science'', is the peer-reviewed scientific journal of the British Ornithologists' Union. It was established in 1859. Topics covered include ecology, conservation, behaviour, palaeontology, and taxonomy of birds. The editor-in-chief is Dominic J. McCafferty (University of Glasgow). The journal is published by Wiley-Blackwell in print and online. It is available free on the internet for institutions in the developing world through the OARE scheme (Online Access to Research in the Environment). History In 1858 the British Ornithologists' Union (BOU) was formed. It was the first organization, devoted solely to the study of birds. One year later members of the BOU founded a (Quarterly) "Magazine of General Ornithology," entitled ''The Ibis''. Series and editors * Series 1 was published from 1859 to 1864, in six volumes and 24 issues. The first editor was Philip Lutley Sclater (1829–1913).Sep. ixv ...

Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Vaurie
Charles Vaurie (7 July 1906, Beaulieu-sur-Dordogne, France – 13 May 1975, Reading, Pennsylvania) was a French-born American ornithologist. He was born in France, but moved to Trenton, New Jersey as a youth. He studied at New York University and then qualified as a dentist at the University of Pennsylvania in 1928. An interest in painting birds developed, and after marrying his entomologist wife, Patricia Wilson, in 1934, the two shared numerous field trips. Vaurie became associated with the American Museum of Natural History and by 1946 he was a Research Associate. He went on to produce more than 150 ornithological publications.

It is a medium-sized nuthatch, measuring between and . The are bluish gray. The male can be distinguished from the female by the black front of its . The species is sedentary; it feeds on arthropods in summer and on seeds in winter. The breeding season takes place around May–June. The nest, built in a hole of tree, shelters a laying of three or four eggs, brooded by the female. The chicks are fed by both parents. The Kabyle nuthatch is the only bird species endemic to Algeria, where it now inhabits only certain coniferous forests in the north of the country. Its scientific name pays tribute to Jean-Paul Ledant, a Belgian amateur naturalist who discovered the bird in October 1975 and named him " La Sittelle Kabyle" (''The Kabyle nuthatch''); the description of the bird was made by the French ornithologist Jacques Viell ...

Corsican Nuthatch
The Corsican nuthatch (''Sitta whiteheadi'') is a species of bird in the nuthatch family Sittidae. It is a relatively small nuthatch, measuring about in overall length. The are bluish gray, the grayish white. The male is distinguished from the female by its entirely black . The species is sedentary, territorial and not very shy. It often feeds high in Corsican pines, consuming mainly pine nuts, but also catching some flying insects. The breeding season takes place between April and May; the nest is placed in the trunk of an old pine, and the clutch has five to six eggs. The young fledge 22 to 24 days after hatching. The Corsican nuthatch is found only on the island of Corsica, where it populates the old forests of high altitude laricio pines, descending lower in winter. Its scientific name comes from John Whitehead, the ornithologist who brought the bird to the attention of the scientific community in 1883.
