Pink Pigeon
The pink pigeon (''Nesoenas mayeri'') is a species of pigeon in the family Columbidae endemic to Mauritius. The pink pigeon nearly became extinct in the 1970s and the 1990s and is still very rare. It is the only Mascarene pigeon that has not become extinct. It was on the brink of extinction in 1991 when only 10 individuals remained, but its numbers have increased due to the efforts of the Durrell Wildlife Conservation Trust since 1977. While the population remains at below 500 birds as of 2011, the IUCN downlisted the species from Critically endangered to Endangered on the IUCN Red List in 2000, and then downlisted it again to Vulnerable in 2018. Taxonomy and evolution Initially classified as a true pigeon, the pink pigeon was reclassified in a monotypic genus by Tommaso Salvadori. Recent DNA analyses suggest its nearest relative is the geographically close Malagasy turtle dove (''Streptopelia picturatus''), and it has thus been suggested that it be placed in the genus ''Strep ...

ÃŽle Aux Aigrettes
Ile aux Aigrettes is an islet off the south-east coast of Mauritius. It functions as a nature reserve and a scientific research station. It is also a popular visitors attraction - both for tourists and for Mauritians. Geography It has an area of and is the largest islet in the Grand Port bay, off the south-east coast of Mauritius and roughly a kilometer () from the coastal town of Mahebourg. It is low-lying and is formed from coral-limestone (unlike the majority of Mauritius which is from volcanic rock). Nature reserve and conservation ''Ile aux Aigrettes'' conserves the world's only remaining piece of ''"Mauritius Dry Coastal Forest"'' - a once plentiful vegetation type. It is therefore home to a large number of extremely rare or Endangered Species, endangered species of plants and animals. Over several hundred years, indigenous flora and fauna was devastated by logging and invasive species. In this sense, the islet shared the same fate as the rest of Mauritius. The Dodo ...

Réunion Pink Pigeon
The Réunion pink pigeon (''Nesoenas mayeri duboisi'', but see below) is an extinct subspecies of pigeon that formerly lived on the Mascarene island of Réunion. It is known from the description of a rusty-red pigeon given by Sieur Dubois, Dubois in 1674 and a single subfossil humerus that agrees with that of the pink pigeon of Mauritius in generic characteristics, except being slightly longer. Also, Dubois' reference to the bill being red at the base and the eyes being surrounded by a red ring suggest that this species was closely allied to the Mauritius taxon. Dubois' description was as follows: It is considered a subspecies of the pink pigeon. Its genus ''Nesoenas'' was often synonymized with ''Columba (genus), Columba'' in the past, but more recently it has been synonymized with ''Streptopelia''. As the pink pigeon and the Malagasy turtle dove cannot be firmly placed in either of these two genera but apparently represent a distinct lineage that diverged early, probably from t ...

Crab-eating Macaque
The crab-eating macaque (''Macaca fascicularis''), also known as the long-tailed macaque and referred to as the cynomolgus monkey in laboratories, is a cercopithecine primate native to Southeast Asia. A species of macaque, the crab-eating macaque has a long history alongside humans. The species has been alternately seen as an agricultural pest, a sacred animal, and, more recently, the subject of medical experiments. The crab-eating macaque lives in matrilineal social groups of up to eight individuals dominated by females. Male members leave the group when they reach puberty. It is an opportunistic omnivore and has been documented using tools to obtain food in Thailand and Myanmar. The crab-eating macaque is a known invasive species and a threat to biodiversity in several locations, including Hong Kong and western New Guinea. The significant overlap in macaque and human living space has resulted in greater habitat loss, synanthropic living, and inter- and intraspecies conflict ...

Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gizzard
The gizzard, also referred to as the ventriculus, gastric mill, and gigerium, is an organ found in the digestive tract of some animals, including archosaurs (pterosaurs, crocodiles, alligators, dinosaurs, birds), earthworms, some gastropods, some fish, and some crustaceans. This specialized stomach constructed of thick muscular walls is used for grinding up food, often aided by particles of stone or grit. In certain insects and molluscs, the gizzard features chitinous plates or teeth. Etymology The word ''gizzard'' comes from the Middle English ''giser'', which derives from a similar word in Old French ''gésier'', which itself evolved from the Latin ''gigeria'', meaning giblets. Structure In birds Birds swallow food and store it in their crop if necessary. Then the food passes into their glandular stomach, also called the proventriculus, which is also sometimes referred to as the true stomach. This is the secretory part of the stomach. Then the food passes into the gizza ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pink Pigeon Image 004
Pink is the color of a namesake flower that is a pale tint of red. It was first used as a color name in the late 17th century. According to surveys in Europe and the United States, pink is the color most often associated with charm, politeness, sensitivity, tenderness, sweetness, childhood, femininity, and romance. A combination of pink and white is associated with chastity and innocence, whereas a combination of pink and black links to eroticism and seduction. In the 21st century, pink is seen as a symbol of femininity, though this has not always been true; in the 1920s, pink was seen as a color that reflected masculinity. In nature and culture File:Color icon pink v2.svg, Various shades of pink File:Dianthus.jpg, The color pink takes its name from the flowers called pinks, members of the genus ''Dianthus''.

Crop Milk
Crop milk is a secretion from the lining of the crop of parent birds that is regurgitated to young birds. It is found among all pigeons and doves where it is referred to as pigeon milk. An analog to crop milk is also secreted from the esophagus of flamingos and the male emperor penguin. Description Crop milk bears little physical resemblance to mammalian milk. Crop milk is a semi-solid substance somewhat like pale yellow cottage cheese. It is extremely high in protein and fat, containing higher levels than cow or human milk. A 1939 study of pigeon crop milk showed, however, that the substance did not contain carbohydrates. It has also been shown to contain anti-oxidants and immune-enhancing factors which contribute to milk immunity. Like mammalian milk, crop milk contains IgA antibodies. It also contains some bacteria. Unlike mammalian milk, which is an emulsion, pigeon crop milk consists of a suspension of protein-rich and fat-rich cells that proliferate and detach fro ...

Ligustrum Robustum
''Ligustrum robustum'' grows as a shrub or small tree up to tall though old specimens of more than a hundred years have been observed with a height of . The fruit of the shrub is an ellipsoid berry, bluish-purple when fully ripe, × . The shrub is native to South and Southeast Asia ( Sri Lanka, India, Bangladesh, Myanmar (Burma), Cambodia, Thailand, Laos, Vietnam) but has become naturalized in other countries. It was introduced to Mauritius at the end of the 19th century and to La Réunion, where it has become a major invasive species. The Flora of China lists a "''Ligustrum'' ''robustum'' subsp. ''chinense'' P. S. Green" as native to China, but more recent publications have regarded that name as a synonym of '' L. expansum.'' ''Ligustrum robustum'' was nominated among 100 of the "World's Worst" invasive species. A moth ('' Epiplema albida''), and two coleoptera ('' Dermorhytis ornatissima'' and '' Dermorhytis lewisi'') are being tested for biological control prog ...

Privet
A privet is a flowering plant in the genus ''Ligustrum''. The genus contains about 50 species of erect, deciduous or evergreen shrubs, sometimes forming small or medium-sized trees, native to Europe, north Africa, Asia, many introduced and naturalised in Australasia, where only one species, ''Ligustrum australianum'', extends as a native into Queensland. Some species have become widely naturalized or invasive where introduced. ''Privet'' was originally the name for the European semi-evergreen shrub '' Ligustrum vulgare'', and later also for the more reliably evergreen '' Ligustrum ovalifolium'' and its hybrid '' Ligustrum × ibolium'' used extensively for privacy hedging, though now the name is applied to all members of the genus. The generic name was applied by Pliny the Elder (23–79 CE) to ''L. vulgare''. It is often suggested that the name ''privet'' is related to ''private'', but the OED states that there is no evidence to support this. Description Privet is a group of ...

Psidium Cattleianum
''Psidium cattleyanum (World Plants : Psidium cattleianum)'', commonly known as Cattley guava, strawberry guava or cherry guava, is a small tree (2–6 m tall) in the Myrtaceae (myrtle) family. The species is named in honour of English horticulturist William Cattley. Its genus name ''Psidium'' comes from the Latin ''psidion'', or "armlet." The red-fruited variety, ''P. cattleyanum var. cattleyanum'', is commonly known as purple guava, red cattley guava, red strawberry guava and red cherry guava. The yellow-fruited variety, ''P. cattleyanum var. littorale'' is variously known as yellow cattley guava, yellow strawberry guava, yellow cherry guava, lemon guava and in Hawaii as ''waiawī''.

Black River Gorges National Park
Black River Gorges National Park is a national park in the hilly south-western part of Mauritius. It was proclaimed on June 15, 1994 and is managed by the National Parks and Conservation Service. It covers an area of 67.54 km² including humid upland forest, drier lowland forest and marshy heathland. Facilities for visitors include two information centres, picnic areas and 60 kilometres of trails. There are four field stations in the park which are used for National Parks and Conservation Service and Mauritian Wildlife Foundation research and conservation projects. The park protects most of the island's remaining rainforest although much of this has been degraded by introduced plants such as Chinese guava and privet and animals such as rusa deer and wild pigs. Several areas have been fenced off and invasive species have been eradicated from them to preserve native wildlife. Many endemic plants and animals still occur in the park including the Mauritian flying fox and all of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
