Cecropis (tribe)
''Cecropis'' is a genus of large swallows found in Africa and tropical Asia. The red-rumped swallow's range also extends into southern Europe, and (in small numbers) into Australia. This genus is frequently subsumed into the larger genus ''Hirundo''. The swallow family Hirundinidae consists of 92 bird species which typically hunt insects in flight. The two river martins have long been recognised as very distinctive, and are placed in a separate subfamily, Pseudochelidoninae, leaving all other swallows and martins in the Hirundininae. DNA studies suggest that there are three major groupings within the Hirundininae subfamily, broadly correlating with the type of nest built. The groups are the "core martins" including burrowing species like the sand martin, the "nest-adopters", with birds like the tree swallow which use natural cavities, and the "mud nest builders". The ''Cecropsis'' species construct a closed mud nest and therefore belong to the latter group. It is believed that t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-rumped Swallow
The European red-rumped swallow (''Cecropis rufula'') is a small passerine bird in the swallow family Hirundinidae. It breeds in open hilly country of southern Europe and north Africa east to Iran, Pakistan and northwest India. During winter it migrates to Africa and southwest Asia. It was formerly considered to be a subspecies of the eastern red-rumped swallow (''Cecropis daurica''), united under the common name of “red-rumped swallow”. European red-rumped swallows are somewhat similar in habits and appearance to the other aerial insectivores, such as the related swallows and the unrelated swifts (order Apodiformes). They have blue upperparts and dusky underparts. They resemble barn swallows, but are darker below and have pale or reddish rumps, face and neck collar. They lack a breast band, but have black undertails. They are fast fliers and they swoop on insects while airborne. They have broad but pointed wings. European red-rumped swallows build quarter-sphere nests with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retort
In a chemistry laboratory, a retort is a device used for distillation or dry distillation of substances. It consists of a sphere, spherical vessel with a long downward-pointing neck. The liquid to be distilled is placed in the vessel and heated. The neck acts as a condenser (laboratory) , condenser, allowing the vapors to condense and flow along the neck to a collection vessel placed underneath. In the chemical industry, a retort is an airtight vessel in which substances are heated for a chemical reaction producing gaseous products to be collected in a collection vessel or for further processing. Such industrial-scale retorts are used in shale oil extraction , shale-oil extraction, in the production of charcoal and in the recovery of Mercury (element) , mercury in gold-mining processes or from hazardous waste. A process of heating oil shale to produce shale oil, oil shale gas, and spent shale is commonly called retorting. Airtight vessels to apply pressure as well as heat a ...

Rufous-bellied Swallow
The rufous-bellied swallow (''Cecropis badia'') is a species of swallow that breeds on the Malay Peninsula. It has faintly streaked deep rufous Rufous () is a color that may be described as reddish-brown or brownish- red, as of rust or oxidised iron. The first recorded use of ''rufous'' as a color name in English was in 1782. However, the color is also recorded earlier in 1527 as a d ... underparts, and an unstreaked rump. It is usually raised to species status from its closest relative, the striated swallow.

Sri Lanka Swallow
The Sri Lanka swallow (''Cecropis hyperythra'') is a resident breeder endemic to Sri Lanka. It is closely related to the red-rumped swallow, and was formerly considered a subspecies. Description It is a large swallow with a tail which forks deeply, and the combination of deep rufous underside and navy blue rump without any marks is a unique feature of this species. Its rufous underside can be used to tell it apart from the red-rumped swallow. It is a passerine A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped') which includes more than half of all bird species. Sometimes known as perching birds, passerines generally have an anisodactyl arrangement of their ..., which means it has three toes pointing forward and one pointing backward, allowing it to perch. Habitat It is found in a variety of open country habitats in both the lowlands and foothills in Sri Lanka, including farm fields and lightly wooded areas. Behaviour It usu ...

African Red-rumped Swallow
The African red-rumped swallow (''Cecropis melanocrissus'') is small passerine bird in the swallow family Hirundinidae. It is found in northern areas of Africa south of the Sahara. Taxonomy The African red-rumped swallow was formally described and illustrated in 1845 by the German naturalist Eduard Rüppell based on a specimen collected in the Tembien region of northern Ethiopia. He coined the binomial name ''Cecropis melanocrissus'' where the specific epithet combines the Latin ''melas'', ''melanos'' meaning "black" with Modern Latin ''crissum'' meaning "vent". Four subspecies are recognised: * ''C. m. domicella'' ( Heuglin, 1869) – west Africa from Senegambia to east Sudan * ''C. m. melanocrissus'' Rüppell, 1845 – Ethiopia and Eritrea * ''C. m. kumboensis'' ( Bannerman, 1923) – Sierra Leone and west Cameroon * ''C. m. emini'' (Reichenow Anton Reichenow (1 August 1847 in Charlottenburg – 6 July 1941 in Hamburg) was a German ornithologist and herpetologist.

Eastern Red-rumped Swallow
The eastern red-rumped swallow (''Cecropis daurica'') is a small passerine bird in the swallow family Hirundinidae. It is found in open, often hilly, areas with clearings and cultivation across Southeast Asia to north-eastern India and Taiwan. The European red-rumped swallow and the African red-rumped swallow were formerly considered as subspecies of the eastern red-rumped swallow. Taxonomy The eastern red-rumped swallow was formally described in 1769 by the Finnish-Swedish clergyman, explorer and natural scientist Erik Laxmann as ''Hirundo daurica'', using a specimen from Mount Schlangen, near Zmeinogorsk, Russia.Prior to the Dickinson paper, the type location had been listed as "the Sung-hua Chiang, Heilungkiang, China near its confluence with the Amur River" as, for example, in Turner (1989) pp. 201–204 It is now placed in the genus ''Cecropis'' created by German scientist Friedrich Boie in 1826. column 971 Boie's genus name ''Cecropis'' is from the Ancient Greek for an ...
