Barquisimeto
Barquisimeto (; ) is a city in Venezuela. Barquisimeto is located in the Central-Western Region, Venezuela. It is the capital of the state of Lara (state), Lara and head of Iribarren Municipality. It is an important urban, industrial, commercial and transportation center of the country, recognized as the fourth-largest city by population and area in Venezuela after Caracas, Maracaibo and Valencia, Venezuela, Valencia. History Barquisimeto was founded in 1552 by Juan de Villegas, as a headquarters and to have better control of the territory believed to be rich in gold. Its original name was Nueva Segovia de Barquisimeto and then it was shortened to just Barquisimeto. This city changed locations four times between 1552 and 1563. The original settlement was near the Buría River, but moved in 1556 due to frequent floods suffered by inhabitants. The second location was in the valley of the Turbio River (Venezuela), Turbio River, where the city stayed until Lope de Aguirre burned i ...

Supercilium
The supercilium is a plumage feature found on the heads of some bird species. It is a stripe which runs from the base of the bird's beak above its eye, finishing somewhere towards the rear of the bird's head.Dunn and Alderfer (2006), p. 10 Also known as an "eyebrow", it is distinct from the eyestripe, which is a line that runs across the lores, and continues behind the eye. Where a stripe is present only above the lores, and does not continue behind the eye, it is called a supraloral stripe or simply supraloral. On most species which display a supercilium, it is paler than the adjacent feather tracts. The colour, shape or other features of the supercilium can be useful in bird identification. For example, the supercilium of the dusky warbler, an Old World warbler The Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. They are not closely related to the New World warblers. The family held over 400 species in over 70 genera, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1837
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through buildin ...

Cooperative Breeding
Cooperative breeding is a social system characterized by alloparental care: offspring receive care not only from their parents, but also from additional group members, often called helpers. Cooperative breeding encompasses a wide variety of group structures, from a breeding pair with helpers that are offspring from a previous season, to groups with multiple breeding males and females ( polygynandry) and helpers that are the adult offspring of some but not all of the breeders in the group, to groups in which helpers sometimes achieve co-breeding status by producing their own offspring as part of the group's brood. Cooperative breeding occurs across taxonomic groups including birds, mammals, fish, and insects. Costs for helpers include a fitness reduction, increased territory defense, offspring guarding and an increased cost of growth. Benefits for helpers include a reduced chance of predation, increased foraging time, territory inheritance, increased environmental conditions and an ...

Thorn Scrub
Deserts and xeric shrublands are a biome defined by the World Wide Fund for Nature. Deserts and xeric (Ancient Greek 'dry') shrublands form the largest terrestrial biome, covering 19% of Earth's land surface area. Ecoregions in this habitat type vary greatly in the amount of annual rainfall they receive, usually less than annually except in the margins. Generally evaporation exceeds rainfall in these ecoregions. Temperature variability is also diverse in these lands. Many deserts, such as the Sahara, are hot year-round, but others, such as East Asia's Gobi Desert, become quite cold during the winter. Temperature extremes are a characteristic of most deserts. High daytime temperatures give way to cold nights because there is no insulation provided by humidity and cloud cover. The diversity of climatic conditions, though quite harsh, supports a rich array of habitats. Many of these habitats are ephemeral in nature, reflecting the paucity and seasonality of available water.

Tolima Department
Tolima () is one of the 32 departments of Colombia, located in the Andean region, in the center-west of the country. It is bordered on the north and the west by the department of Caldas; on the east by the department of Cundinamarca; on the south by the department of Huila, and on the west by the departments of Cauca, Valle del Cauca, Quindío and Risaralda. Tolima has a surface area of 23,562 km2, and its capital is Ibagué. The department of Tolima was created in 1861 from a part of what was previously Cundinamarca. History Indigenous civilization The Pijao inhabited the southern parts of Tolima during pre-Columbian times. The name of the department comes from the Pijao word for "snowed". The Panche, of the same linguistic family as the Pijao, populated the northern regions of Tolima, close to the Magdalena Valley. Renowned as fierce warriors, the Panche were widely known for fighting the Muisca over the control of emerald mining territories. They fought ...

Huila Department
Huila () is one of the departments of Colombia. It is located in the southwest of the country, and its capital is Neiva. Demography and Ethnography Huila department had a population of 1,122,622 inhabitants in 2020, of which 679,667 (60.54%) live in urban areas and 442,955 (39.46%) in the rest of the ''Huilense'' territory. This amounts to 2.5% of the total Colombian population. The majority of it is settled in the Magdalena valley, the main urban centers being Neiva and Garzón, due to the possibilities offered by commercial-type agricultural economy, oil production, access to basic public services and roads connected to the central road axis along the Magdalena. The rest of the population is located on the coffee belt, standing out Pitalito and La Plata; the North Subregion is undergoing a decrease in its rural population, mainly attributable to alterations of agricultural and oil activities on the landscape. The average population density in the department is 59.88 inh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
