Ouvea Parakeet
The Ouvea parakeet (''Eunymphicus uvaeensis'') or Uvea parakeet, is a species of parrot in the genus '' Eunymphicus'', in the family Psittaculidae. It is endemic to the island of Uvea in the Loyalty Islands, New Caledonia. The species was once considered conspecific with the horned parakeet of Grande Terre, but they have now been split into two species. Description The Ouvea parakeet is a medium-sized parakeet with mostly green plumage and a prominent green crest. The crest is composed of six backward feathers that curl forwards. The underside of the bird tends to be yellower and there is bright blue on the wings and tail. The face is dark and the beak is black, lacking the yellow on the face of the horned parakeet. Diet The species has a preference for natural forests and laurel forest habitat while avoiding coconut plantations and coastal vegetation.Olivier Robinet, Vincent Bretagnolle and Mick Clout (2003) "Activity patterns, habitat use, foraging behaviour and food selec ...

Ouvéa Island
Ouvéa Island or Uvea Island is one of the Loyalty Islands, in the archipelago of New Caledonia, an overseas territory of France in the Pacific Ocean. The island is part of the communes of France, commune (municipality) of Ouvéa, in the Loyalty Islands Province of New Caledonia. Geography The crescent-shaped island, which belongs to a larger atoll, is long and wide. It lies north east of ''Grande Terre'', New Caledonia's mainland. History Ouvéa is a Polynesian outlier originally settled by Polynesian navigation, Polynesian navigators who named it for their home island, Wallis Island, Uvea Island. Some of their descendants still speak the West Uvean language. Demographics Ouvéa is home to around 3,000 people who are organized into tribes divided into Polynesians and Melanesians by ethnic descent. The Iaai language is spoken on the island. Flora and fauna Ouvéa has rich marine resources and is home to many sea turtles, species of fish, coral as well as a native parrot, the ...

Bird Nest
A bird nest is the spot in which a bird lays and Avian incubation, incubates its Bird egg, eggs and raises its young. Although the term popularly refers to a specific structures built by animals, structure made by the bird itself—such as the grassy cup nest of the American robin or Eurasian blackbird, or the elaborately woven hanging nest of the Montezuma oropendola or the village weaver—that is too restrictive a definition. For some species, a nest is simply a shallow depression made in sand; for others, it is the knot-hole left by a broken branch, a burrow dug into the ground, a chamber drilled into a tree, an enormous rotting pile of vegetation and earth, a shelf made of dried saliva or a mud dome with an entrance tunnel. The smallest bird nests are those of some hummingbirds, tiny cups which can be a mere across and high. At the other extreme, some nest mounds built by the dusky scrubfowl measure more than in diameter and stand nearly tall. The study of birds' nests ...

Birds Described In 1882
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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings 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 furt ...

Extinction
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...

Habitat Loss
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and Abundance (ecology), species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the Exploitation of natural resources, use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduced species, introduction of invasive species, ecosystem nutrient depletion, water pollution, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Rat
The black rat (''Rattus rattus''), also known as the roof rat, ship rat, or house rat, is a common long-tailed rodent of the stereotypical rat genus '' Rattus'', in the subfamily Murinae. It likely originated in the Indian subcontinent, but is now found worldwide. The black rat is black to light brown in colour with a lighter underside. It is a generalist omnivore and a serious pest to farmers because it feeds on a wide range of agricultural crops. It is sometimes kept as a pet. In parts of India, it is considered sacred and respected in the Karni Mata Temple in Deshnoke. Taxonomy ''Mus rattus'' was the scientific name proposed by Carl Linnaeus in 1758 for the black rat. Three subspecies were once recognized, but today are considered invalid and are now known to be actually color morphs: *''Rattus rattus rattus'' – roof rat *''Rattus rattus alexandrinus'' – Alexandrine rat *''Rattus rattus frugivorus'' – fruit rat Characteristics A typical adult black rat is ...

Handbook Of The Birds Of The World
The ''Handbook of the Birds of the World'' (HBW) is a multi-volume series produced by the Spanish publishing house Lynx Edicions in partnership with BirdLife International. It is the first handbook to cover every known living species of bird. The series was edited by Josep del Hoyo, Andrew Elliott, Jordi Sargatal and David A. Christie. All 16 volumes have been published. For the first time an animal class will have all the species illustrated and treated in detail in a single work. This has not been done before for any other group in the animal kingdom. Material in each volume is grouped first by family, with an introductory article on each family; this is followed by individual species accounts (taxonomy, subspecies and distribution, descriptive notes, habitat, food and feeding, breeding, movements, status and conservation, bibliography). In addition, all volumes except the first and second contain an essay on a particular ornithological theme. More than 200 renowned sp ...

Brown Goshawk
The brown goshawk (''Tachyspiza fasciata'') is a medium-sized bird of prey in the family Accipitridae found in Australia and surrounding islands. This species was formerly placed in the genus ''Accipiter''. Taxonomy The brown goshawk was formally described in 1827 by the naturalists Nicholas Vigors and Thomas Horsfield under the binomial name ''Astur fasciatus''. The type locality is the state of New South Wales in eastern Australia. The brown goshawk was formerly placed in the genus ''Accipiter''. In 2024 a comprehensive molecular phylogenetic study of the Accipitridae confirmed earlier work that had shown that the genus was polyphyletic. To resolve the non-monophyly, ''Accipiter'' was divided into six genera. The genus '' Tachyspiza'' was resurrected to accommodate the brown goshawk together with 26 other species that had previously been placed in ''Accipiter''. The resurrected genus had been introduced in 1844 by the German naturalist Johann Jakob Kaup. The genus name com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fledge
Fledging is the stage in a flying animal's life between egg, hatching or birth and becoming capable of flight. This term is most frequently applied to birds, but is also used for bats. For altricial birds, those that spend more time in vulnerable condition in the nest, the nestling and fledging stage can be the same. For precocial birds, those that develop and leave the nest quickly, a short nestling stage precedes a longer fledging stage. All birds are considered to have fledged when the feathers and wing muscles are sufficiently developed for flight. A young bird that has recently fledged but is still dependent upon parental care and feeding is called a fledgling. People often want to help fledglings, as they appear vulnerable, but it is best to leave them alone. The USA National Phenology Network defines the phenophase (or life cycle stage) of fledged young for birds as "One or more young are seen recently departed from the nest. This includes young incapable of sustained ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avian Incubation
Egg incubation is the process by which an egg, of oviparous (egg-laying) animals, develops an embryo within the egg, after the egg's formation and ovipositional release. Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg. Multiple and various factors are vital to the incubation of various species of animal. In many species of reptile for example, no fixed temperature is necessary, but the actual temperature determines the sex ratio of the offspring. In birds, the sex of offspring is genetically determined, but in many species a constant and particular temperature is necessary for successful incubation. Especially in poultry, the act of sitting on eggs to incubate them is called brooding. The action or behavioral tendency to sit on a clutch of eggs is also called broodiness, and most egg-laying breeds of poultry have had this behavior selectively bred out of them to increase production. Avian incubation A wide rang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
