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 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 navigators who named it for their home island, Uvea Island. Some of their descendants still speak the West Uvean language. Demographics Ouvéa is home to around 3,016 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 Uvea parakeet, that can only be found on the isla ...

Ficus
''Ficus'' ( or ) is a genus of about 850 species of woody trees, shrubs, vines, epiphytes and hemiepiphytes in the family Moraceae. Collectively known as fig trees or figs, they are native throughout the tropics with a few species extending into the semi-warm temperate zone. The common fig (''F. carica'') is a temperate species native to southwest Asia and the Mediterranean region (from Afghanistan to Portugal), which has been widely cultivated from ancient times for its fruit, also referred to as figs. The fruit of most other species are also edible though they are usually of only local economic importance or eaten as bushfood. However, they are extremely important food resources for wildlife. Figs are also of considerable cultural importance throughout the tropics, both as objects of worship and for their many practical uses. Description ''Ficus'' is a pantropical genus of trees, shrubs, and vines occupying a wide variety of ecological niches; most are evergr ...

Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the Endling, last individual of the species, although the Functional extinction, capacity to breed and recover may have been lost before this point. Because 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. More than 99% of all species that ever Life, lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct a ...

Habitat Loss
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 resource exploitation, 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, ...

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 long, ...

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 spec ...

Brown Goshawk
The brown goshawk (''Accipiter fasciatus'') is a medium-sized bird of prey in the family Accipitridae found in Australia and surrounding islands. Description Its upperparts are grey with a chestnut collar; its underparts are mainly rufous, finely barred with white. Thus it has similar colouring to the collared sparrowhawk but is larger. The flight is fast and flexible. The body length is ; the wingspan, . Females are noticeably larger: adult males weigh , and adult females, . Distribution and habitat The brown goshawk is widespread through Australia, Wallacea, New Guinea, New Caledonia, Vanuatu and Fiji. In Australia, it is found mainly in eucalypt forests and woodlands, as well as farmland and urban areas. In the Pacific, it mainly inhabits rainforest. It was also found on Norfolk Island to about 1790, and this may be another undescribed subspecies. However, the lack of specimens from Norfolk Island (1 historical skin and 9 subfossil bones is all the material that has b ...

Fledge
Fledging is the stage in a flying animal's life between 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 Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonal and interannual variations in climate, as well as habitat factors (suc ...

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 in contrast, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Egg
Bird eggs are laid by the females and range in quantity from one (as in condors) to up to seventeen (the grey partridge). Clutch size may vary latitudinally within a species. Some birds lay eggs even when the eggs have not been fertilized; it is not uncommon for pet owners to find their lone bird nesting on a clutch of infertile eggs, which are sometimes called wind-eggs. Anatomy All bird eggs contain the following components: * The embryo is the immature developing chick * The amnion is a membrane that initially covers the embryo and eventually fills with amniotic fluid, provides the embryo with protection against shock from movement * The allantois helps the embryo obtain oxygen and handles metabolic waste * The chorion, together with the amnion, forms the amniotic sac and encloses the amnion, vitellus, and the embryo * The vitellus, or yolk, is the nutrient-bearing portion of the egg, containing most of its fat, minerals, and many of its proteins and blood vessels * The al ...
