Magdalena Tinamou
The Magdalena tinamou, ''Crypturellus erythropus saltuarius'', is a member of one of the most ancient bird families, the tinamous. It is endemic to the Magdalena River Valley in Colombia, and had been considered possibly extinct, because of an absence of confirmed records since the type specimen was collected in 1943. The most recent review consider it likely that it is extant, as locals have reported sightings in the 1970s and 1980s, an individual was apparently held in captivity until the early 1990s, and a few patches of forest remain in its presumed range.Donegan, T. ''et al.'' (2003) Additionally, a record was made in late 2008. It was rediscovered in 2023. It is sometimes treated as a distinct species, and sometimes as a subspecies of the red-legged tinamou. The SACC rejected a proposal to elevate it to species status, arguing that the presently available data fail to support the split.Remsen Jr., J. V. ''et al'' (2006) BirdLife International have followed this treat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Wetmore
Frank Alexander Wetmore (June 18, 1886 – December 7, 1978) was an American ornithologist and avian paleontologist. He was the sixth Secretary of the Smithsonian Institution. Early life and education The son of a Country Physician, Frank Alexander Wetmore was born in North Freedom, Wisconsin. Developing an interest in birds at an early age, he made his first field journal entry (a pelican seen while on vacation in 1894) at the age of eight. By 1900, Wetmore published his first paper "My Experience with a Red-headed Woodpecker," in the magazine Bird-Lore. To further his education Wetmore enrolled at the University of Kansas in 1905. During his studies there he did a stint as an assistant in the University Museum, under the direction of Charles D. Bunker. Alexander Wetmore later received his BA from the University of Kansas in 1912; finally receiving his MS in 1916 & PhD in 1920 from George Washington University. Wetmore began federal service in 1910, working for the Biological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cesar Department
Caesar Department ( es, Departamento del Cesar, links=no) or simply Caesar () is a department of Colombia located in the north of the country in the Caribbean region, bordering to the north with the Department of La Guajira, to the west with the Department of Magdalene and Department of Bolivar, to the south with Department of Santander, to the east with the Department of North Santander, and further to the east with the country of Venezuela ( Zulia State). The department capital city is Valledupar. The region was first inhabited by indigenous peoples known as Euparis in the Valley of Upar and Guatapuris in the Valley of the Caesar river, among these were the Orejones pertaining to the Toupeh, Acanayutos pertaining to the Motilon and Alcoholades pertaining to the Chimila. The first European to explore the area was Spanish Captain Peter Vadillo, but German Ambrose Alfinger savagely conquered the region in 1532. From 1996–2006 paramilitary groups committed gross human ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plumage
Plumage ( "feather") is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morphs. The placement of feathers on a bird is not haphazard, but rather emerge in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month o ...

Ornithologist
Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them." Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across life forms, and the number of scientists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almos ...

Habitat (ecology)
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] |
Deforestation
Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then land conversion, converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban area, urban use. The most concentrated deforestation occurs in tropical rainforests. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, a half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. The Food and Agriculture Organization, Food and Agriculture Organization of the United Nations defines deforestation as the conversion of forest to other land uses (regardless of whether it is human-induced). "Deforestation" and "forest area net change" are not the same: the latter is the sum of all forest losses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serranía De San Lucas
The Serranía de San Lucas is a forested massif in the Bolívar Department of northern Colombia that reaches heights of 2,600m above sea level. It is part of the Magdalena-Urabá moist forests ecoregion, with a rainforest ecology that includes large monkey and bird populations. It is a 'forest reserve' that has been recommended for protection, but has been opened to mining by the Colombian government, as the mountains have large deposits of gold, emeralds, nickel and mercury Mercury commonly refers to: * Mercury (planet), the nearest planet to the Sun * Mercury (element), a metallic chemical element with the symbol Hg * Mercury (mythology), a Roman god Mercury or The Mercury may also refer to: Companies * Merc .... AngloGold Ashanti has been exploring in the area since 2004, causing tensions with local small-scale miners. The ELN guerrilla group enforced forest protection in the area in the early 2000s, apparently to protect local hydrology. The area is still subject ...

Deciduous
In the fields of horticulture and Botany, the term ''deciduous'' () means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit. The antonym of ''deciduous'' in the botanical sense is evergreen. Generally, the term "deciduous" means "the dropping of a part that is no longer needed or useful" and the "falling away after its purpose is finished". In plants, it is the result of natural processes. "Deciduous" has a similar meaning when referring to animal parts, such as deciduous antlers in deer, deciduous teeth (baby teeth) in some mammals (including humans); or decidua, the uterine lining that sheds off after birth. Botany In botany and horticulture, deciduous plants, including trees, shrubs and herbaceous perennials, are those that lose all of their leaves for part of the year. This process is called a ...

Neiva, Colombia
Neiva () is the capital of the Department of Huila. It is located in the valley of the Magdalena River in south central Colombia with a population of about 357,392 inhabitants. It is one of the most important cities in southern Colombia, mainly because of its strategic geographical location. History Neiva was first founded in 1539 by Juan de Cabrera in an area now belonging to the municipality of Campoalegre. In 1550, Juan de Alonso y Arias relocated the city to the place that is now the municipality of Villavieja. At this location, the city was destroyed by indigenous tribes in 1560. The city was founded, at its current location, for the third and final time in 1612 by Diego de Ospina y Medinilla. Neiva became important during the colonial times because of its strategic location. It was located in the trade route that communicated the Viceroyalty of Peru with Bogotá and Caracas. The city was declared as the capital of the Province of Neiva, made up of the Neiva, La Plata, Ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
