Little Grebe
The little grebe (''Tachybaptus ruficollis''), also known as dabchick, is a member of the grebe family of water birds. The genus name is from Ancient Greek ''takhus'' "fast" and ''bapto'' "to sink under". The specific ''ruficollis'' is from Latin ''rufus'' "red" and Neo-Latin, Modern Latin ''-collis'', "-necked", itself derived from Latin ''collum'' "neck". At in length it is the smallest European member of its family. It is commonly found in open bodies of water across most of its range. Taxonomy The little grebe was described by the German naturalist Peter Simon Pallas in 1764 and given the binomial name ''Colymbus ruficollis''. The tricolored grebe was formerly considered conspecific, with some taxonomic authorities still considering it so. Subspecies Seven subspecies are currently accepted, four widespread, and three with restricted ranges; they are separated principally by size, eye colour, which varies from dark to light from west to east, and extent of white on the seco ...

Buoyancy
Buoyancy (), or upthrust, is the force exerted by a fluid opposing the weight of a partially or fully immersed object (which may be also be a parcel of fluid). In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus, the pressure at the bottom of a column of fluid is greater than at the top of the column. Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object. The pressure difference results in a net upward force on the object. The magnitude of the force is proportional to the pressure difference, and (as explained by Archimedes' principle) is equivalent to the weight of the fluid that would otherwise occupy the submerged volume of the object, i.e. the Displacement (fluid), displaced fluid. For this reason, an object with average density greater than the surrounding fluid tends to sink because its weight is greater than the weight of the fluid it displaces. If the objec ...

He joined his family business in carving and gilding and studied at the School of Design in Somerset House. Suffering from ill health, he spent two years in a business house at Civitavecchia owned by a friend of his father. His initial aim was to enter a mercantile career. On returning to England in 1851 he was induced to enter the newly established Royal School of Mines (now part of Imperial College London), which his younger brother Henry Francis Blanford, Henry F. Blanford (1834–1893), afterwards head of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tigris–Euphrates River System
The Tigris–Euphrates river system is a large river system in West Asia that flows into the Persian Gulf. Its primary rivers are the Tigris and Euphrates, along with smaller tributary, tributaries. From their sources and upper courses in the Armenian highlands of eastern Turkey, being Lake Hazar for the Tigris and Karasu (Euphrates), Karasu along with the Murat River for the Euphrates, the two rivers descend through valleys and gorges to the uplands of Syria and northern Iraq and then to the alluvial plain of central Iraq. Other tributaries join the Tigris from sources in the Zagros Mountains to the east. The rivers flow in a south-easterly direction through the central plain and combine at Al-Qurnah to form the Shatt al-Arab and discharge into the Persian Gulf. The rivers and their tributaries drain an area of , including almost the entire area of Iraq as well as portions of Turkey, Syria, Iran and Kuwait. The region has historical importance as part of the Fertile Crescent, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tachybaptus Ruficollis Iraquensis, Al Jahra Governorate, Kuwait 1
''Tachybaptus'' is a genus of small birds of the grebe family. The genus name means "quick diving": it is from Ancient Greek ''takhys'' "quick" and ''bapto'' "I dip". It has representatives over much of the world, including the tropics. These grebes breed in small colonies in heavily vegetated areas of freshwater lakes. They may move to more open or coastal waters when not breeding, and birds in those areas where the waters freeze may be migratory. Like all grebes, they nest on the water's edge, since the legs are set very far back and they cannot walk well. The striped young are sometimes carried on the adult's back. These small grebes are excellent swimmers and divers, and pursue their fish prey underwater. The sexes are similar: dumpy and short-billed with a “powder puff” rear end. Adults have a distinctive breeding plumage and loud breeding calls. In winter, they are grey and white. The five Old World species are closely related to each and at least three have interbre ...
