Rose-headed Parakeet
The rose-crowned parakeet (''Pyrrhura rhodocephala''), also known as the rose-headed parakeet, rose-crowned conure or rose-headed conure (perico cabeza roja or cotorra coronirroja in Spanish and conure tête-de-feu in French), is a species of parrot in the family Psittacidae and genus Pyrrhura. It is endemic to Venezuela. Taxonomy The rose-crowned parakeet was first described by Philip Sclater and Osbert Salvin in 1871. Description The rose-crowned parakeet is a small parrot, measuring 24 cm long with a wing length of 13 to 14.2 cm, tail 9.7 to 11.5 cm, and bill 1.6 to 1.8 cm long, with a tarsus length of 1.4 to 1.6 cm. As an adult it is mainly green; its bright red cap and white Covert feather#Wing coverts, primary coverts (blue in juveniles) help to distinguish it from all other long-tailed, small parrot species in South America. It has blue Flight feather#Remiges, primaries and a red tail and the sexes are alike. No other members of the genus ''Pyrrhura ...

Philip Sclater
Philip Lutley Sclater (4 November 1829 – 27 June 1913) was an England, English lawyer and zoologist. In zoology, he was an expert ornithologist, and identified the main zoogeographic regions of the world. He was Secretary of the Zoological Society of London for 42 years, from 1860–1902. Early life Sclater was born at Tangier Park, in Wootton St Lawrence, Hampshire, where his father William Lutley Sclater had a country house. George Sclater-Booth, 1st Baron Basing was Philip's elder brother. Philip grew up at Hoddington House where he took an early interest in birds. He was educated in school at Twyford and at thirteen went to Winchester College and later Corpus Christi College, Oxford where he studied scientific ornithology under Hugh Edwin Strickland. In 1851 he began to study law and was admitted a Fellow of Corpus Christi College. In 1856 he travelled to America and visited Lake Superior and the upper St. Croix River (Wisconsin–Minnesota), St. Croix River, cano ...

Habitat
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 interi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of The Venezuelan Andes
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 ...

Parakeets
A parakeet is any one of many small to medium-sized species of parrot, in multiple genera, that generally has long tail feathers. Etymology and naming The name ''parakeet'' is derived from the French wor''perroquet'' which is reflected in some older spellings that are still sometimes encountered, including paroquet or paraquet. However, in modern French''perruche''is used to refer to parakeets and similar-sized parrots. In American English, the word ''parakeet'' usually refers to the budgerigar, which is one species of parakeet. Summary Parakeets comprise about 115 species of birds that are seed-eating parrots of small size, slender build, and long, tapering tails. The Australian budgerigar, also known as "budgie", ''Melopsittacus undulatus'', is probably the most common parakeet. It was first described by zoologists in 1891. It is the most popular species of parakeet kept as a pet in North America and Europe. The term "grass parakeet" (or ''grasskeet'') refers to ...

World Parrot Trust
The World Parrot Trust is an international charity dedicated to saving parrots. History When the Trust was founded in 1989 at Paradise Park in Cornwall, UK, it was decided that the main objective was to promote the survival of all parrot species and the welfare of individual birds, both in the wild and in captivity. The Trust has achieved these aims by funding vital conservation work, research projects and educational programmes, both locally and internationally. Fundraising Over its nearly thirty-year span the Trust has raised some $2.0 M US and has used these funds to begin and support conservation and welfare projects in 43 countries for 70 species of parrot. The Trust has expanded globally to include national branches in Africa, Australia, Belgium, Canada, Italy, Netherlands, Scandinavia, Spain and the United States. Parrot Action Plan In 1999, the Trust joined with the IUCN to publish the Parrot Action Plan, to help protect 89 species of parrot from habitat destruction ...

CITES
CITES (shorter name for the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention) is a multilateral treaty to protect endangered plants and animals from the threats of international trade. It was drafted as a result of a resolution adopted in 1963 at a meeting of members of the International Union for Conservation of Nature (IUCN). The convention was opened for signature in 1973 and CITES entered into force on 1 July 1975. Its aim is to ensure that international trade (import/export) in specimens of animals and plants included under CITES, does not threaten the survival of the species in the wild. This is achieved via a system of permits and certificates. CITES affords varying degrees of protection to more than 38,000 species. , Secretary-General of CITES is Ivonne Higuero. Background CITES is one of the largest and oldest conservation and sustainable use agreements in existence. There are three working langu ...

Deforestation
Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or 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 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 (deforestation) and all forest gains (forest expansion) in a ...

Princeton University Press
Princeton University Press is an independent publisher with close connections to Princeton University. Its mission is to disseminate scholarship within academia and society at large. The press was founded by Whitney Darrow, with the financial support of Charles Scribner, as a printing press to serve the Princeton community in 1905. Its distinctive building was constructed in 1911 on William Street in Princeton. Its first book was a new 1912 edition of John Witherspoon's ''Lectures on Moral Philosophy.'' History Princeton University Press was founded in 1905 by a recent Princeton graduate, Whitney Darrow, with financial support from another Princetonian, Charles Scribner II. Darrow and Scribner purchased the equipment and assumed the operations of two already existing local publishers, that of the ''Princeton Alumni Weekly'' and the Princeton Press. The new press printed both local newspapers, university documents, ''The Daily Princetonian'', and later added book publishing ...

Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evalu ...

Near Threatened
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of re-evaluating near-threatened taxon at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Near-threatened species evaluated from 2001 onwards may also be ones which are dependent on conservation efforts to prevent their becoming threatened, whereas before this conservation-dependent species were given a separate category ("Conservation Dependent"). Additionally, the 402 conservation-dependent taxa may also be considered near-threatened. IUCN Categories and Criteria version 2.3 Before 2001, the IUCN used the version 2.3 Categories and Criteri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
