Moorea Reed Warbler
Moorea reed warbler (''Acrocephalus longirostris'') is a species of songbird in the genus ''Acrocephalus (bird), Acrocephalus''. Formerly placed in the "Old World warbler" assemblage (Sylviidae), it is now in the newly recognized marsh warbler family Acrocephalidae. It was once considered a subspecies of the Tahiti reed warbler. Distribution and habitat It is endemic to Moorea in the Society Islands. It occurs in second-growth forest as well as Schizostachyum glaucifolium, Polynesian 'ohe thickets (and likely breeds exclusively in the latter) in river valleys and hillsides. Description It has two color morphs; a light morph that is pale yellow with mottled brownish above, and an olive-brown dark morph. Conservation It was last seen in 1987, and was previously feared to have gone extinct due to habitat destruction by Hydroelectricity, hydroelectric power, road-building, and exploitation of bamboo, as well as the introduction of the invasive species such as the Miconia calvescens, ...

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, introdu ...

Birds Described In 1789
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. Bird ...

Feral Cat
A feral cat or a stray cat is an unowned domestic cat (''Felis catus'') that lives outdoors and avoids human contact: it does not allow itself to be handled or touched, and usually remains hidden from humans. Feral cats may breed over dozens of generations and become an aggressive local apex predator in urban, savannah and bushland environments. Some feral cats may become more comfortable with people who regularly feed them, but even with long-term attempts at socialization, they usually remain aloof and are most active after dusk. Feral cats are devastating to wildlife, and conservation biologists consider them to be one of the worst invasive species on Earth. Attempts to control feral cat populations are widespread but generally of greatest impact within purpose-fenced reserves. Some animal rights groups advocate trap-neuter-return programs to prevent the feral cats from continuing to breed. Scientific evidence has demonstrated that TNR is not effective at controlling f ...

Miconia Calvescens
''Miconia calvescens'', the velvet tree, miconia, or bush currant, is a species of flowering plant in the family Melastomataceae. It is native to Mexico and Central and South America and it has become one of the world's most invasive species. Miconia trees can flower several times a year and bear fruit simultaneously. The inflorescences are large panicles of white to light pink blossoms. The tiny purple fruits are about half a centimeter in diameter and packed with about 120–230 minuscule seeds. The sweet fruits are attractive to birds and other animals which disperse the seeds. A young tree with only two flower panicles can produce seeds in its first fruiting season. This heavy seed production and potential for long-distance dispersal help make miconia an invasive threat. The seeds can lie dormant in the soil of the forest for more than 12 years, and whenever a break in the canopy allows sun to shine through to a patch of soil the seeds there undergo germination. Once the pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectricity
Hydroelectricity, or hydroelectric power, is Electricity generation, electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other Renewable energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Schizostachyum Glaucifolium
''Schizostachyum glaucifolium'', common name Polynesian ohe, is a species of bamboo. Distribution This species is native to the South-Central Pacific, from the Marquesas Islands and Society Islands in French Polynesia, as well as in the Southwestern Pacific in the Samoan Islands and Fiji. It is an introduced species in Hawaii. Habitat This species prefers tropical or subtropical climates. It can be found mainly along the banks of rivers and streams and on hillsides, at an elevation of above sea level. Description ''Schizostachyum glaucifolium'' can reach a typical height of and a culm diameter of . This evergreen clump-forming bamboo shows thin walls, long internodes and yellow woody culms with green stripes. Human culture These bamboos have been used in French Polynesia by ancient Polynesians for its many uses (baskets, mats, musical instruments, small containers, fishing rods, etc.). Samoans consider its (known as ''ʻofe'' in Samoan) shoots as a sign of misfortune and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Songbird
A songbird is a bird belonging to the suborder Passeri of the perching birds (Passeriformes). Another name that is sometimes seen as the scientific or vernacular name is Oscines, from Latin ''oscen'', "songbird". The Passeriformes contains 5000 or so speciesEdwards, Scott V. and John Harshman. 2013. Passeriformes. Perching Birds, Passerine Birds.

Songbirds form one of the two major lineages of extant perching birds (~4000 species), the other being the Tyranni (~1000 species), which are most diverse in the Neotropics and absent from many parts of the world. The Tyranni have a simpler syrinx musculature, and while their vocalizations are often just as complex and striking as thos ...

Society Islands
The Society Islands (french: Îles de la Société, officially ''Archipel de la Société;'' ty, Tōtaiete mā) are an archipelago located in the South Pacific Ocean. Politically, they are part of French Polynesia, an overseas country of the French Republic. Geographically, they form part of Polynesia. The archipelago is believed to have been named by Captain James Cook during his first voyage in 1769, supposedly in honour of the Royal Society, the sponsor of the first British scientific survey of the islands; however, Cook wrote in his journal that he called the islands ''Society'' "as they lay contiguous to one another." History Dating colonization The first Polynesians are understood to have arrived on these islands around 1000AD. Oral history origin The islanders explain their origins in term of a orally transmitted story. The feathered god Ta'aroa lay in his shell. He called out but no-one answered, so he went back into his shell, where he stayed for aeons. When he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moorea
Moorea ( or ; Tahitian: ), also spelled Moorea, is a volcanic island in French Polynesia. It is one of the Windward Islands, a group that is part of the Society Islands, northwest of Tahiti. The name comes from the Tahitian word , meaning "yellow lizard": = lizard ; (from ) = yellow. An older name for the island is ', sometimes spelled or (among other spellings that were used by early visitors before Tahitian spelling was standardized). Early Western colonists and voyagers also referred to Moorea as ''York Island'' or ''Santo Domingo''. History Prehistory According to recent archaeological evidence, the Society Islands were probably settled from Samoa and Tonga around 200 CE.Patrick V.
