Buff-tailed Sicklebill
:Epimachus albertisi'', a bird-of-paradise from New Guinea, is also sometimes called "buff-tailed sicklebill".'' The buff-tailed sicklebill (''Eutoxeres condamini'') is a species of hermit hummingbird from the lower Andes and adjacent west Amazonian lowlands from southern Colombia and northern Ecuador to Peru and Bolivia.Hinkelmann (1999) Description With a total length of and weighing , it is a relatively large hummingbird. Males and females are virtually identical, differing only in size (especially wing measurements), with the females being some 20% smaller. Its upperparts are iridescent dull greenish, while the underparts are whitish, densely streaked with dusky. The neck-side has a relatively faint blue patch. The tips of the rectrices (tail feathers) are white, and there is a naked stripe on top of the head (but this is usually concealed). The most conspicuous features, however, are those the common name refers to: the bill is strongly decurved, and the outer three rectr ...

Epimachus Albertisi
The black-billed sicklebill (''Drepanornis albertisi''), also known as the buff-tailed sicklebill (leading to easy confusion with the hummingbird of the same name), is a species of bird-of-paradise. It, along with its congener, are the only members of the genus ''Drepanornis.'' Conservation status Widespread throughout its large range, the black-billed sicklebill is evaluated as being of least concern on the IUCN Red List of Threatened Species. It is listed on Appendix II of CITES. Etymology The generic name ''Drepanornis'' consists of the words ''Drepane'' for "sickle" and ''ornis'' for "bird", so the genus name literally means "sickle bird", referring to their sickle-shaped bill; the specific name commemorates the Italian naturalist Luigi Maria d'Albertis, who discovered this species in 1872. The race ''cervinicauda'' subspecific name consists of ''cervinus'' for "stag-colored" and "''cauda"'' for tail, ''geisleri'' honors Bruno Geisler, a German ornithologist who described ...

Down (feather)
The down of birds is a layer of fine feathers found under the tougher exterior feathers. Very young birds are clad only in down. Powder down is a specialized type of down found only in a few groups of birds. Down is a fine thermal insulator and padding, used in goods such as jackets, bedding (duvets and featherbeds), pillows and sleeping bags. The discovery of feathers trapped in ancient amber suggests that some species of dinosaur may have possessed down-like feathers. Description and etymology The word ''down'' comes from the Old Norse word ''dúnn'', which had the same meaning as its modern equivalent. The down feather is considered to be the most "straightforward" of all feather types. It has a short or vestigial rachis (shaft), few barbs, and barbules that lack hooks. There are three types of down: natal down, body down and powder down. Natal down is the layer of down feathers that cover most birds at some point in their early development. Precocial nestlings are alread ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Above Mean Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humid
Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point. The amount of water vapor needed to achieve saturation increases as the temperature increases. As the temperature of a parcel of air decreases it will eventually reach the saturation point without adding or losing water mass. The amount of water vapor contained within a parcel of air can vary significantly. For example, a parcel of air near saturation may contain 28 g of water per cubic metre of air at , but only 8 g of water per cubic metre of air at . Three primary measurements of humidity are widely employed: absolute, relative, and specific. Abs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Putumayo Department
Putumayo () is a department of Southern Colombia. It is in the south-west of the country, bordering Ecuador and Peru. Its capital is Mocoa. The word ''putumayo'' comes from the Quechua languages. The verb ''p'utuy'' means "to spring forth" or "to burst out", and ''mayu'' means river. Thus it means "gushing river". History Originally, the southwestern area of the department belonged to the Cofán Indians, the northwestern to the Kamentxá Indians, the central and southern areas to tribes that spoke Tukano languages (such as the Siona), and the eastern to tribes that spoke Witoto languages. Part of the Kamentxá territory was conquered by the Inca Huayna Cápac in 1492, who, after crossing the Cofán territory, established a Quechua population on the valley of Sibundoy, known today as Ingas. After the Inca defeat in 1533, the region was invaded by the Spanish in 1542, and from 1547 was administered by Catholic missions. The current territory of Putumayo was linked to Pop ...

Sympatric
In biology, two related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter one another. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not shared ranges and do no ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. 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 taxonomy (biology), 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 ...

Jean Stanislaus Stolzmann
Jan Stanisław Sztolcman (sometimes referred to as Jean Stanislaus Stolzmann) (19 November 1854, Warsaw – 28 April 1928, Warsaw) was a Polish ornithologist. Biography Beginning in 1872, Sztolcman studied zoology at the Imperial University of Warsaw. From 1875 to 1882, he collected zoological specimens in South America, primarily in Peru, and from 1882 to 1884, he lived and worked in Ecuador. He collected several hundred species of birds from South America, with some of the specimens being little known or entirely unknown to European ornithologists. In 1884, he returned to Warsaw, where in 1887 he was appointed director of the Branickich zoological museum. Eponyms Taxa with the specific epithet of ''stolzmanni'' commemorate his name. For example, two species of lizard are named in his honor: ''Liolaemus stolzmanni'' and ''Microlophus stolzmanni''. Written works Among Sztolcman's written works is a 1926 treatise on the European bison, titled ''Żubr, jego historia, obyczaje ...
