Helmeted Woodpecker
The helmeted woodpecker (''Celeus galeatus'') is a species of bird in the family Picidae. It has been recorded from far northeastern Argentina, southeastern Brazil, and eastern Paraguay. Its habitat is subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. It is threatened by habitat loss. Taxonomy Coenraad Jacob Temminck described the helmeted woodpecker in 1822. Its specific epithet is from the Latin word ''galea'', meaning "helmet". It was reclassified as ''Hylatomus galeatus'' by some authorities. Upon sequencing the mitochondrial and nuclear DNA, two studies published in 2015 found that it lay genetically with the latter genus and proposed the name ''Celeus galeatus''. The placement of the helmeted woodpecker in the genus ''Celeus'' was accepted by the International Ornithologists' Union. Its genetic position indicates that it has evolved to mimic the lineated woodpecker (''Dryocopus lineatus''), whose range it shares, by adopting simi ...

Celeus (bird)
''Celeus'' is a genus of bird in the woodpecker family, Picidae, found in tropical and subtropical forests and woodlands of Central and South America. The genus contains 13 extant species. One, Kaempfer's woodpecker (''C. obrieni''), was believed to be extinct until a specimen was caught in 2006. The species in the genus are medium-sized, in length (with chestnut woodpecker (''Celeus elegans'') the longest), and weigh between . They have limited plumage colour with the head and crest mainly lighter in colour. The feet, tail, tongue and bill of the birds in the genus are adapted for the specialised resources required for its survival and reproduction (for example breeding sites and large food supplies). They are native residents and do not migrate. They are generally insectivorous but will eat seeds and fruits. The birds are monogamous with both sexes sharing nest and brooding care. Some species nest communally. Many live near humans but are seen as destructive in agri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iguazú National Park
The Iguazú National Park ( es, Parque Nacional Iguazú) is a national park of Argentina, located in the Iguazú Department, in the north of the province of Misiones, Argentine Mesopotamia. It has an area of . History The area of the park was inhabited 10,000 years ago by the hunter-gatherers of the ''Eldoradense'' culture. They were displaced around 1,000 Common Era, CE by the Guaraní, who brought new agricultural technologies, and were displaced in turn by the Spanish and Portuguese conquistadores in the 16th century, though their legacy is still alive in this area (the name of the park and the river is Guaraní ''y guasu'', "large water"). The first European to visit the zone was Álvar Núñez Cabeza de Vaca, in 1542; Jesuit missions followed in 1609. The park was created in 1934 to protect one of the greatest natural beauties of Argentina, the Iguazu Falls, surrounded by the subtropical jungle.

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

Lineated Woodpecker
The lineated woodpecker (''Dryocopus lineatus'') is a very large woodpecker which is a resident breeding bird from southern Mexico to northern Argentina and on Trinidad in the Caribbean. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the lineated woodpecker in his ''Ornithologie'' based on a specimen collected in Cayenne, French Guiana. He used the French name ''Le pic noir hupé de Cayenne'' and the Latin name ''Picus niger cayanensis cristatus''. The two stars (**) at the start of the section indicates that Brisson based his description on the examination of a specimen. Although Brisson coined Latin names, these do not conform to the Binomial nomenclature, binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the 12th edition of Systema Naturae, 12th edition, he added 240 species that had been previously desc ...

Mimicry
In evolutionary biology, mimicry is an evolved resemblance between an organism and another object, often an organism of another species. Mimicry may evolve between different species, or between individuals of the same species. Often, mimicry functions to protect a species from predators, making it an anti-predator adaptation. Mimicry evolves if a receiver (such as a predator) perceives the similarity between a mimic (the organism that has a resemblance) and a model (the organism it resembles) and as a result changes its behaviour in a way that provides a selective advantage to the mimic. The resemblances that evolve in mimicry can be visual, acoustic, chemical, tactile, or electric, or combinations of these sensory modalities. Mimicry may be to the advantage of both organisms that share a resemblance, in which case it is a form of mutualism; or mimicry can be to the detriment of one, making it parasitic or competitive. The evolutionary convergence between groups is driven by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
