Yellow-knobbed Curassow
The yellow-knobbed curassow (''Crax daubentoni'') is a species of bird in the family Cracidae, the chachalacas, guans, and curassows. It is found in Colombia and Venezuela. Taxonomy and systematics The yellow-knobbed curassow was formerly classified as a subspecies of blue-billed curassow (''Crax alberti''). It is monotypic. A few subspecies previously proposed for it were determined to be hybrids or aberrant individuals and so were not adopted.del Hoyo, J. and G. M. Kirwan (2020).

Birds Described In 1867
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight 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 orders. More than half are passerine or "perching" birds. Birds have 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 loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, ...

Curassows
Curassows are one of the three major groups of cracid birds. They comprise the largest-bodied species of the cracid family. Three of the four genera are restricted to tropical South America; a single species of ''Crax'' ranges north to Mexico. They form a distinct clade which is usually classified as the subfamily Cracinae. Evolution In line with the other 3 main lineages of cracids (chachalacas, true guans, and the horned guan), mt and nDNA sequence data indicates that the curassows diverged from their closest living relatives (probably the guans) at some time during the Oligocene, or c.35–20 mya (Pereira ''et al.'' 2002). This data must be considered preliminary until corroborated by material (e.g. fossil) evidence however. What appears certain from analysis of the molecular data, calibrated against geological events that would have induced speciation, is that there are 2 major lineages of curassows: one containing only ''Crax'', and another made up of ''Mitu'' and ''P ...

Crax
''Crax'' is a genus of curassows in the order Galliformes, a clade of large, heavy-bodied, ground-feeding birds. They are known from tropical South America with one species, the great curassow, ranging northwards through Central America as far as Mexico. The curassows in this genus are noted for their sexual dimorphism; males are more boldly coloured than females and have facial ornamentation such as knobs and wattles. They are also characterised by curly crests and contrastingly-coloured crissa (the area around the cloaca). ''Crax'' curassows probably originated as a distinct lineage during the Late Miocene. During the Messinian, the ancestral Crax split into two lineages separated by the Colombian Andes and the Cordillera de Mérida which uplifted at that time. The northern lineage radiated into the great, blue-billed, and yellow-knobbed curassows, while the four southern species evolved as they became separated by the uplifting of various mountain ranges.

Philadelphia Zoo
The Philadelphia Zoo is a zoo located in the Centennial District of Philadelphia on the west bank of the Schuylkill River. It was the first true zoo in the United States; it was chartered by the Commonwealth of Pennsylvania on March 21, 1859, but its opening was delayed by the Civil War until July 1, 1874. The zoo opened with 1,000 animals and an admission price of 25 cents. For a brief time, the zoo also housed animals brought to U.S. from safaris by the Smithsonian Institution, which had not yet built its National Zoo. The Philadelphia Zoo is one of the premier zoos in the world for breeding animals that are difficult to breed in captivity. The zoo also works with many groups around the world to protect the natural habitats of the animals in their care. The zoo is and the home of nearly 1,300 animals, many of which are rare and endangered. Special features include a children's petting zoo, a rainforest themed carousel, a climbing structure, chats with keepers, behind th ...

Hamerton Zoo Park
Hamerton Zoo Park is situated in Hamerton, near Sawtry, Huntingdonshire, England. Development Planning permission for change of use from agricultural land to a zoo was granted in 1988, with the park being opened on 15 June 1990 by local MP, then-Chancellor, and future Prime Minister John Major. The zoo has two large wind turbines to provide power for the park erected during the second half of November 2012; the zoo was described as being the "most environmentally-friendly zoo in Europe" in 2014. An application for two 50 kW turbines was turned down in August 2015 by Huntingdonshire District Council. Conservation The zoo has a conservation sanctuary which has a collection of nearly 100 different species including rare / endangered animals and birds. Tiger incident The park was evacuated on the morning of 29 May 2017 after what was described as a 'serious incident'. It was later confirmed that zookeeper A zookeeper, sometimes referred as animal keeper, is a person who ma ... [...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 ...

Polygynous
Polygyny () is a form of polygamy entailing the marriage of a man to several women. The term polygyny is from Neoclassical Greek πολυγυνία (); . Incidence Polygyny is more widespread in Africa than in any other continent. Some scholars theorize that the History of slavery, slave trade's impact on the male-to-female sex ratio was a key factor in the emergence and fortification of polygynous practices in regions of Africa. Polygyny is most common in a region known as the "polygamy belt" in West Africa and Central Africa, with the countries estimated to have the highest polygamy prevalence in the world being Burkina Faso, Mali, Gambia, Niger and Nigeria. In the region of sub-Saharan Africa, polygyny is common and deeply rooted in the culture, with 11 percent of the population of sub-Saharan Africa living in such marriages (25 percent of the Muslim population and 3 percent of the Christian population, as of 2019). Polygyny is especially widespread in West Africa, with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Llanos
The Llanos ( Spanish ''Los Llanos'', "The Plains"; ) is a vast tropical grassland plain situated to the east of the Andes in Colombia and Venezuela, in northwestern South America. It is an ecoregion of the tropical and subtropical grasslands, savannas, and shrublands biome. Geography The Llanos occupy a lowland that extends mostly east and west. The Llanos are bounded on the west and northwest by the Andes, and on the north by the Venezuelan Coastal Range. The Guiana Highlands are to the southeast, and the Negro-Branco moist forests are to the southwest. To the east the Orinoco wetlands and Orinoco Delta swamp forests occupy the Orinoco Delta. The Llanos' main river is the Orinoco, which runs from west to east through the ecoregion and forms part of the border between Colombia and Venezuela. The Orinoco is the major river system of Venezuela. Climate The ecoregion has a tropical savanna climate that grades into a tropical monsoon climate in the Colombian Llanos. Rainfal ...

Gallery Forest
A gallery forest is one formed as a corridor along rivers or wetlands, projecting into landscapes that are otherwise only sparsely treed such as savannas, grasslands, or deserts. The gallery forest maintains a more temperate microclimate above the river. Defined as long and narrow forest vegetation associated with rivers, gallery forests are structurally and floristically heterogeneous. The habitats of these forests differ from the surrounding landscapes because they are, for example, more nutrient-rich or moister and/or there is less chance of fires. The forests are sometimes only a few meters wide, because they depend on the water they lie along. Ecology characteristics The riparian zones in which they grow offer greater protection from fire which would kill tree seedlings. In addition, the alluvial soils of the gallery habitat are often of higher fertility and have better drainage than the soils of the surrounding landscape with a more reliable water supply at depth.
