Blue-knobbed Curassow
The blue-billed curassow (''Crax alberti'') is a species of bird in the family Cracidae, the chachalacas, guans, and curassows. It is endemic to Colombia. Taxonomy and systematics The blue-billed curassow is monotypic. However, it formerly included what is now the yellow-knobbed curassow (''Crax daubentoni'') as a subspecies. The holotype of putative species ''C. annulata'' has been determined to be a female blue-billed curassow.Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S. Claramunt, A. Jaramillo, D. F. Lane, J. F.

Louis Fraser
Louis Fraser (1819 – c. 1883) was a British Zoology, zoologist and collector. In his early years, Fraser was curator of the Museum of the Zoological Society of London. Little is known about Fraser's early life. He was born in 1819 or 1820 and married Mary Ann Harrison on 17 February 1844. A son Oscar L. Fraser worked as an assistant in the Indian Museum at Calcutta around 1888. He worked for fourteen years at the museum of the Zoological Society of London. He worked with the anatomist Richard Owen on studies of the emu and rhea. He participated in the Niger expedition of 1841 as the African Civilization Society's scientist, with William Allen (admiral), Allen and Thomas Richard Heywood Thomson, Thomson. He stayed on in Fernando Po and collected. Upon his return he became in charge of Edward Smith-Stanley, 13th Earl of Derby, Lord Derby's collection at Knowsley Hall. In 1846 he was sent by Lord Derby to collect in north Africa. In 1848 he became conservator at Knowsley. He wrote ''Z ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
La Guajira Department
La Guajira () is a department of Colombia. It occupies most of the Guajira Peninsula in the northeast region of the country, on the Caribbean Sea and bordering Venezuela, at the northernmost tip of South America. The capital city of the department is Riohacha. Various indigenous tribes have populated the arid plains of the region long before the Spanish expeditions reached the Americas. In 1498, Alonso de Ojeda sailed around the peninsula of La Guajira, but the first European to set foot in what is known today as La Guajira was the Spanish explorer Juan de la Cosa in 1499. During the colonial era, the territory of La Guajira was disputed by the governors of Santa Marta and Venezuela, owing to deposits of pearls. English pirates, Frenchmen, and Germans also fought for control of the territory. Martin Fernandez de Enciso founded Nuestra Señora Santa María de los Remedios del Cabo de la Vela, the first colonial village in the territory. In 1535, Nicolás de Federmán refounded ...

Birds Described In 1852
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 ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have 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, have further evolved for swimming. Birds ...

Curassows
The chachalacas, guans and curassows are birds in the Family (biology), family Cracidae. These are species of tropical and subtropical Central America, Central and South America. The range of one species, the plain chachalaca, just reaches southernmost parts of Texas in the United States. Two species, the Trinidad piping guan and the rufous-vented chachalaca occur on the islands of Trinidad and Tobago respectively. Systematics and evolution The family Cracidae was introduced (as Craxia) by the French polymath Constantine Samuel Rafinesque in 1815. The Cracidae are an ancient group related to the Australasian Megapode, mound-builders. They are sometimes united with these in a distinct order (biology), order, "Craciformes", but this is not supported by more recent research which suggests that either is a well-marked, Basal (phylogenetics), basal lineage of Galliformes. Phylogeny Cladogram based on the study by De Chen and collaborators published in 2021. The numbers of species are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 crissums (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.

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and 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 building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boyacá Department
Boyacá () is one of the thirty-two departments of Colombia, and the remnant of Boyacá State, one of the original nine states of the "United States of Colombia". Boyacá is centrally located within Colombia, almost entirely within the mountains of the Eastern Cordillera to the border with Venezuela, although the western end of the department extends to the Magdalena River at the town of Puerto Boyacá. Boyacá borders to the north with the Department of Santander, to the northeast with the Bolivarian Republic of Venezuela and Norte de Santander, to the east with the departments of Arauca and Casanare. To the south, Boyacá borders the department of Cundinamarca and to the west with the Department of Antioquia covering a total area of . The capital of Boyacá is the city of Tunja. Boyacá is known as "The Land of Freedom" because this region was the scene of a series of battles which led to Colombia's independence from Spain. The first one took place on 25 July 1819 in ...

Wattle (anatomy)
A wattle is a fleshy caruncle hanging from various parts of the head or neck in several groups of birds and mammals. Caruncles in birds include those found on the face, wattles, dewlaps, snoods, and earlobes. Wattles are generally paired structures, but may occur as a single structure when it is sometimes known as a dewlap. Wattles are frequently organs of sexual dimorphism. In some birds, caruncles are erectile tissue and may or may not have a feather covering. Wattles are often such a striking morphological characteristic of animals that it features in their common name. For example, the southern and northern cassowaries are known as the double-wattled and single-wattled cassowary, respectively, and a breed of domestic pig is known as the Red Wattle. Birds Function In birds, wattles are often an ornament for courting potential mates. Large wattles are correlated with high testosterone levels, good nutrition, and the ability to evade predators, which in turn indicates a ...
