Tibetan Blackbird
The Tibetan blackbird (''Turdus maximus'') is a species of bird in the thrush family Turdidae. It is found in the Himalayas from northern Pakistan to southeastern Tibet. Originally described as a separate species by Henry Seebohm in 1881, it was then considered a subspecies of the common blackbird until 2008, when phylogenetic evidence revealed that it was only distantly related to the latter species. It is a relatively large thrush, having an overall length of . Males are blackish-brown all over with darker plumage on the head, breast, wings and tail and dull orange-yellow bills, while females have browner , faint streaking on the throat, and a dull darkish yellow bill. Both sexes may seem slightly hooded. It can be differentiated from the common blackbird by its complete lack of an eye-ring and reduced song. The Tibetan blackbird inhabits steep grassy, rocky slopes and alpine meadows above the tree line. Usually found at elevations of , it descends to lower elevations in t ...

Henry Seebohm
Henry Seebohm (12 July 1832 – 26 November 1895) was an English steel manufacturer, and amateur ornithologist, oologist and traveller. Biography Henry was the oldest son of Benjamin Seebohm (1798–1871) who was a wool merchant at Horton Grange, Bradford. The family had moved to England from Bad Pyrmont in Germany. Henry's mother Estther Wheeler (1798–1864) was a granddaughter of William Tuke. The Seebohms were active in the Society of Friends and Henry schooled within the community in York. He worked initially in a grocery as an assistant but moved to Sheffield where he became a steel manufacturer. He married Maria, daughter of George John Healey, a merchant in Manchester on 19 January 1859. Natural history Henry became interested in natural history at school and continued to spend his spare time studying birds on his journeys. He travelled widely visiting Greece, Scandinavia, Turkey, and South Africa. His expeditions to the Yenisey tundra of Siberia were described in ...

Clutch (eggs)
A clutch of eggs is the group of eggs produced by birds, amphibians, or reptiles, often at a single time, particularly those laid in a nest. In birds, destruction of a clutch by predators (or removal by humans, for example the California condor breeding program) results in ''double-clutching''. The technique is used to double the production of a species' eggs, in the California condor case, specifically to increase population size. Size Clutch size differs greatly between species, sometimes even within the same genus. It may also differ within the same species due to many factors including habitat, health, nutrition, predation pressures, and time of year. Clutch size variation can also reflect variation in optimal reproduction effort. In birds, clutch size can vary within a species due to various features (age and health of laying female, ability of male to supply food, and abundance of prey), while some species are determinant layers, laying a species-specific number of egg ...

Generic Name (biology)
Genus (; : genera ) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demonstrate both monophyly and validity as a separate lineage). ...

Systematic Biology
Systematics is the study of the diversification of living forms, both past and present, and the relationships among living things through time. Relationships are visualized as evolutionary trees (synonyms: phylogenetic trees, phylogenies). Phylogenies have two components: branching order (showing group relationships, graphically represented in cladograms) and branch length (showing amount of evolution). Phylogenetic trees of species and higher taxa are used to study the evolution of traits (e.g., anatomical or molecular characteristics) and the distribution of organisms (biogeography). Systematics, in other words, is used to understand the evolutionary history of life on Earth. The word systematics is derived from the Latin word of Ancient Greek origin '' systema,'' which means systematic arrangement of organisms. Carl Linnaeus used 'Systema Naturae' as the title of his book. Branches and applications In the study of biological systematics, researchers use the different branch ...

Turdus
''Turdus'' is a genus of medium-sized mostly insectivorous or omnivorous birds in the wider thrush family, Turdidae. The genus name ''Turdus'' is Latin for 'thrush'. Most of the species are called thrushes; the term thrush is also used for many other birds in the family Turdidae, as well as for a few species belonging to other families. Some Old World species with fully or largely black plumage are called blackbirds, and one, the ring ouzel, still retains the Old English name ouzel, which, until the 17th century, was also used (as "black ouzel") for the common blackbird; it is cognate with the German name Amsel for the same species. Some New World species are called robins, the best known of which is the American robin. Two other species have their own distinct names without "thrush", fieldfare and redwing, derived from behavioural characteristics and plumage features, respectively. The genus has a cosmopolitan distribution, with species in Europe, Asia, Africa, and the Ame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

British Ornithologists' Club
The British Ornithologists' Club (BOC) aims to promote discussion between members and others interested in ornithology, and to facilitate the dissemination of scientific information concerned with ornithology. The BOC has a special interest in avian systematics, taxonomy and distribution. The BOC was founded at a meeting of 15 members of the British Ornithologists' Union held in Covent Garden, London on 5 October 1892. This was at a time when individuals and expeditions were exploring remote parts of the world, discovering many new species of birds in the process and the BOC was formed to enable members to meet regularly to present papers, exhibit specimens and engage in discussion on wider ornithological matters. The BOC has continued to meet regularly in London (with occasional meetings elsewhere) and, as at June 2012, has held 970 meetings. Meetings now take the form of a talk followed by discussion, with refreshments available afterwards. Meetings are free and are open to me ...

Kashmir
Kashmir ( or ) is the Northwestern Indian subcontinent, northernmost geographical region of the Indian subcontinent. Until the mid-19th century, the term ''Kashmir'' denoted only the Kashmir Valley between the Great Himalayas and the Pir Panjal Range. The term has since also come to encompass a larger area that includes the Indian-administered territories of Jammu and Kashmir (union territory), Jammu and Kashmir and Ladakh, the Pakistani-administered territories of Azad Kashmir and Gilgit-Baltistan, and the Chinese-administered territories of Aksai Chin and the Trans-Karakoram Tract. Quote: "Kashmir, region of the northwestern Indian subcontinent. It is bounded by the Uygur Autonomous Region of Xinjiang to the northeast and the Tibet Autonomous Region to the east (both parts of China), by the Indian states of Himachal Pradesh and Punjab to the south, by Pakistan to the west, and by Afghanistan to the northwest.
