Réunion Bulbul
The Réunion bulbul (''Hypsipetes borbonicus'') is a species of the bulbul family of passerine birds. It is endemic to Réunion. Taxonomy and systematics The Réunion bulbul was originally described in the genus ''Turdus''. Formerly, some authorities also considered the Mauritius bulbul to be a subspecies of the Réunion bulbul.Staub (1976), Gregory (2000), BLI (2008) Alternate names for the Réunion bulbul include the Bourbon thrush, olivaceous bulbul, Réunion black bulbul and Réunion merle. Description The appearance of the Réunion bulbul is similar to that of the Mauritius bulbul but is slightly smaller with a length of 22 cm. It is ashy gray with a blackish crest and the iris is conspicuously white. The bill and feet have an orange hue.Staub (1976) Behaviour and ecology Breeding The female lays two eggs in a cup-shaped nest during the southern summer.

Thomas Pennant
Thomas Pennant (14 June Old Style, OS 172616 December 1798) was a Welsh natural history, naturalist, traveller, writer and antiquarian. He was born and lived his whole life at his family estate, Downing Hall near Whitford, Flintshire, in Wales. As a naturalist he had a great curiosity, observing the geography, geology, plants, animals, birds, reptiles, amphibians and fish around him and recording what he saw and heard about. He wrote acclaimed books including ''British Zoology'', the ''History of Quadrupeds'', ''Arctic Zoology'' and ''Indian Zoology'' although he never travelled further afield than continental Europe. He knew and maintained correspondence with many of the scientific figures of his day. His books influenced the writings of Samuel Johnson. As an antiquarian, he amassed a considerable collection of art and other works, largely selected for their scientific interest. Many of these works are now housed at the National Library of Wales. As a traveller he visited Sco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guava
Guava () is a common tropical fruit cultivated in many tropical and subtropical regions. The common guava ''Psidium guajava'' (lemon guava, apple guava) is a small tree in the myrtle family ( Myrtaceae), native to Mexico, Central America, the Caribbean and northern South America. The name guava is also given to some other species in the genus ''Psidium'' such as strawberry guava (''Psidium cattleyanum'') and to the pineapple guava, '' Feijoa sellowiana''. In 2019, 55 million tonnes of guavas were produced worldwide, led by India with 45% of the total. Botanically, guavas are berries. Types The most frequently eaten species, and the one often simply referred to as "the guava", is the apple guava ('' Psidium guayava''). Guavas are typical Myrtoideae, with tough dark heavy leaves that are opposite, simple, elliptic to ovate, and long. The flowers are white, with five petals and numerous stamens. The fruits are many-seeded berries. Etymology The term ''guava'' appears ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypsipetes
__NOTOC__ ''Hypsipetes'' is a genus of bulbuls, songbirds in the family Pycnonotidae. Most of its species occur in tropical forests around the Indian Ocean. But while the genus is quite diverse in the Madagascar region at the western end of its range it does not reach the African mainland. Most ''Hypsipetes'' bulbuls are dark greyish birds with orange or red bills and feet. The feathers on top of the head are slightly elongated and usually black, and can be erected to form a short and wispy crest. Taxonomy and systematics The genus ''Hypsipetes'' was introduced in 1831 by the Irish zoologist Nicholas Aylward Vigors with ''Hypsipetes psaroides'' as the type species. This taxon is now a subspecies of the black bulbul ''Hypsipetes leucocephalus psaroides''. The genus name combines the Ancient Greek ''hupsi'' meaning "high" with ''petēs'' meaning "-flyer". Species The genus contains 19 species: * Philippine bulbul (''Hypsipetes philippinus'') * Mindoro bulbul (''Hypsipetes mind ...

Ortolan Bunting
The ortolan (''Emberiza hortulana''), also called ortolan bunting, is a Eurasian bird in the bunting family Emberizidae, a passerine family now separated by most modern scholars from the finches, Fringillidae. The genus name ''Emberiza'' is from Alemannic German , a bunting. The specific ''hortulana'' is from the Italian name for this bird, . The English ''ortolan'' is derived from Middle French , "gardener". The ortolan is served in French cuisine, typically cooked and eaten whole. Traditionally diners cover their heads with their napkin, or a towel, while eating the delicacy. The bird is so widely used that its French populations dropped dangerously low, leading to laws restricting its use in 1999. In September 2007, the French government announced its intent to enforce long-ignored laws protecting the bird. Taxonomy The ortolan bunting was described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' and retains its original bin ...

Red-whiskered Bulbul
The red-whiskered bulbul (''Pycnonotus jocosus''), or crested bulbul, is a passerine bird native to Asia. It is a member of the bulbul family. It is a resident frugivore found mainly in tropical Asia. It has been introduced in many tropical areas of the world where populations have established themselves. It has a loud three or four note call, feeds on fruits and small insects and perches conspicuously on trees. It is common in hill forests and urban gardens. Taxonomy The red-whiskered bulbul was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Lanius jocosus''. The specific epithet is from Latin ''ioculus'' meaning "merry" (from ''iocus'' meaning "joke"). Linnaeus based his description on the ''Sitta Chinensis'' that had been described in 1757 by the Swedish naturalist Pehr Osbeck. Linnaeus specified the location as "China" but this was restricted to Hong Kong and Kwangtung (now Guangd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poaching
Poaching has been defined as the illegal hunting or capturing of wild animals, usually associated with land use rights. Poaching was once performed by impoverished peasants for subsistence purposes and to supplement meager diets. It was set against the hunting privileges of nobility and territorial rulers. Since the 1980s, the term "poaching" has also been used to refer to the illegal harvesting of wild plant species. In agricultural terms, the term 'poaching' is also applied to the loss of soils or grass by the damaging action of feet of livestock, which can affect availability of productive land, water pollution through increased runoff and welfare issues for cattle. Stealing livestock as in cattle raiding classifies as theft, not as poaching. The United Nations' Sustainable Development Goal 15 enshrines the sustainable use of all wildlife. It targets the taking of action on dealing with poaching and trafficking of protected species of flora and fauna to ensure their avail ...

International Union For Conservation Of Nature
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 pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Criteria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secondary Forest
A secondary forest (or second-growth forest) is a forest or woodland area which has re-grown after a timber harvest or clearing for agriculture, until a long enough period has passed so that the effects of the disturbance are no longer evident. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early seral forest, as well as third-growth forests that result from harvest in second growth forests. Secondary forest regrowing after timber harvest differs from forest regrowing after natural disturbances such as fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. However, often after natural disturbance the timber is harvested and removed from the system, in which case the system more closely resembles secondary forest rather than seral forest.

Edward Blyth
Edward Blyth (23 December 1810 – 27 December 1873) was an English zoologist who worked for most of his life in India as a curator of zoology at the museum of the Asiatic Society of India in Calcutta. Blyth was born in London in 1810. In 1841 he travelled to India to become the curator of the museum of the Royal Asiatic Society of Bengal. He set about updating the museum's catalogues, publishing a ''Catalogue of the Birds of the Asiatic Society'' in 1849. He was prevented from doing much fieldwork himself, but received and described bird specimens from A.O. Hume, Samuel Tickell, Robert Swinhoe and others. He remained as curator until 1862, when ill-health forced his return to England. His ''Natural History of the Cranes'' was published posthumously in 1881. Avian species bearing his name include Blyth's hornbill, Blyth's leaf warbler, Blyth's hawk-eagle, Blyth's olive bulbul, Blyth's parakeet, Blyth's frogmouth, Blyth's reed warbler, Blyth's rosefinch, Blyth's shrike-babbl ...

Humid
Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point. The amount of water vapor needed to achieve saturation increases as the temperature increases. As the temperature of a parcel of air decreases it will eventually reach the saturation point without adding or losing water mass. The amount of water vapor contained within a parcel of air can vary significantly. For example, a parcel of air near saturation may contain 28 g of water per cubic metre of air at , but only 8 g of water per cubic metre of air at . Three primary measurements of humidity are widely employed: absolute, relative, and specific. Abs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
