White-browed Nuthatch
The white-browed nuthatch (''Sitta victoriae''), also known as the Victoria nuthatch, is a species of bird in the family Sittidae. It is a small nuthatch, measuring in length and without sexual dimorphism. Like many other nuthatches, the are gray-blue, contrasting with white underparts on the throat, cheeks, and breast and orange on the flanks, belly, and lower abdomen. Its white supercilium makes it easy to distinguish it from the white-tailed nuthatch (''S. himalayensis''), which is a close species in the systematic and geographical sense. Little is known about its ecology, but it feeds on small insects found among bark and lichens, and breeding occurs around April. The white-browed nuthatch is endemic to Nat Ma Taung, also known as Mount Victoria, in the southern Chin Hills of Myanmar. It inhabits old oak groves at high elevations, generally above . The numbers of the species are poorly known but are estimated at a few thousand individuals. They ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endangered Species (IUCN Status)
Endangered species as classified by the International Union for Conservation of Nature (IUCN), are species which have been categorized as very likely to become extinct in their known native ranges in the near future. On the IUCN Red List, endangered is the second most severe conservation status for wild populations in the IUCN's schema after critically endangered. In 2012, the IUCN Red List featured 3,079 animal and 2,655 plant species as endangered worldwide. The figures for 1998 were 1,102 and 1,197 respectively. IUCN Red List The IUCN Red List is a list of species which have been assessed according to a system of assigning a global conservation status. According to the latest system used by the IUCN, a species can be "Data Deficient" (DD) species – species for which more data and assessment is required before their situation may be determined – as well species comprehensively assessed by the IUCN's species assessment process. A species can be "Ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sitta
The nuthatches () constitute a genus, ''Sitta'', of small passerine birds belonging to the family Sittidae. Characterised by large heads, short tails, and powerful bills and feet, nuthatches advertise their territory using loud, simple songs. Most species exhibit grey or bluish upperparts and a black eye stripe. Most nuthatches breed in the temperate or montane woodlands of the Northern Hemisphere, although two species have adapted to rocky habitats in the warmer and drier regions of Eurasia. However, the greatest diversity is in Southern Asia, and similarities between the species have made it difficult to identify distinct species. All members of this genus nest in holes or crevices. Most species are non-migratory and live in their habitat year-round, although the North American red-breasted nuthatch migrates to warmer regions during the winter. A few nuthatch species have restricted ranges and face threats from deforestation. Nuthatches are omnivorous, eating mostly i ...

Hans Edmund Wolters
Hans Edmund Wolters (11 February 1915 – 22 December 1991) was a German ornithologist from Duisburg. In 1960, he became an associate member of the Alexander Koenig Zoological Research Institute and Museum in Bonn. He became head of the museum's Department of Ornithology in 1973. He was one of the first European ornithologists to use a cladistic Cladistics (; ) is an approach to biological classification in which organisms are categorized in groups ("clades") based on hypotheses of most recent common ancestry.

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 p ...

Christopher Helm
Christopher Alexander Roger Helm (born Dundee, 1 February 1937 – 20 January 2007) was a Scottish book publisher, notably of ornithology related titles, including the '' Helm Identification Guides''. Born in Dundee, he was raised in Forfar, where his father was a Presbyterian minister. The family moved to Tunbridge Wells at the start of World War II, and he was educated at Harrow School, then, after active duty in Cyprus with the Highland Light Infantry (as National Service), he graduated in classics and law from Gonville and Caius College, Cambridge in 1960. Having worked for Macmillan, he set up and, in turn, sold each of Croom Helm (founded in 1972, bought by Associated Book Publishers in 1986 and merged into the Routledge imprint in 1992), Christopher Helm Publishers and Pica Press (both of the latter pair being bought by A & C Black, now part of Bloomsbury Publishing Plc). He was an active member of the council of the British Ornithologists' Union, becoming vice-p ... [...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. His most important work was a systematic review of Palearctic birds. By 1956, he was a full-time ornithologist at AMNH, and rose to Curator by 1967. At the time of his death he was a member of the Standing Committee on Ornithological Nomenclature of the International Ornithological Congress International is an adjective (also used as a noun) meaning "b ...

Ernst Mayr
Ernst Walter Mayr (; 5 July 1904 – 3 February 2005) was one of the 20th century's leading evolutionary biologists. He was also a renowned taxonomist, tropical explorer, ornithologist, philosopher of biology, and historian of science. His work contributed to the conceptual revolution that led to the modern evolutionary synthesis of Mendelian genetics, systematics, and Darwinian evolution, and to the development of the biological species concept. Although Charles Darwin and others posited that multiple species could evolve from a single common ancestor, the mechanism by which this occurred was not understood, creating the '' species problem''. Ernst Mayr approached the problem with a new definition for species. In his book '' Systematics and the Origin of Species'' (1942) he wrote that a species is not just a group of morphologically similar individuals, but a group that can breed only among themselves, excluding all others. When populations within a species become is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Meinertzhagen
Colonel Richard Meinertzhagen, CBE, DSO (3 March 1878 – 17 June 1967) was a British soldier, intelligence officer, and ornithologist. He had a decorated military career spanning Africa and the Middle East. He was credited with creating and executing the Haversack Ruse in October 1917, during the Sinai and Palestine Campaign of the First World War, but his participation in this matter has since been refuted. While early biographies lionized Meinertzhagen as a master of military strategy and espionage, later works such as ''The Meinertzhagen Mystery'' present him as a fraud for fabricating stories of his feats and speculated he murdered his wife (in addition to extra-judicial killings while in the colonial service). The discovery of stolen museum bird specimens resubmitted as original discoveries has raised serious doubts on the veracity of many of his ornithological records. Background and youth Meinertzhagen was born into a wealthy, socially connected British family. Hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylogenetically
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and doe ...
