Micropsitta Geelvinkiana
The Geelvink pygmy parrot (''Micropsitta geelvinkiana'') is a species of parrot in the family Psittacidae endemic to Biak and Numfoor islands in Western New Guinea. The name Geelvink comes from a Dutch ship and family called Geelvinck. It has two subspecies; the nominate occurs on Numfor, and ''M. g. misoriensis'' on Biak. Description It has a brown head, blue crown, light blue ear covert, yellow breast, green body and blue tail. It has red eyes. The female has less brown than the male. Diet It feeds on lichen, fungi, seeds, fruits, flowers, insects and their larvae. Habitat Its natural habitats are subtropical or tropical moist lowland forests and rural gardens. It is threatened by 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 .... References Geelv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hermann Schlegel
Hermann Schlegel (10 June 1804 – 17 January 1884) was a German ornithologist, herpetologist and ichthyologist. Early life and education Schlegel was born at Altenburg, the son of a brassfounder. His father collected butterflies, which stimulated Schlegel's interest in natural history. The discovery, by chance, of a buzzard's nest led him to the study of birds, and a meeting with Christian Ludwig Brehm. Schlegel started to work for his father, but soon tired of it. He travelled to Vienna in 1824, where, at the university, he attended the lectures of Leopold Fitzinger and Johann Jacob Heckel. A letter of introduction from Brehm to Joseph Natterer gained him a position at the Naturhistorisches Museum. Ornithological career One year after his arrival, the director of this natural history museum, Carl Franz Anton Ritter von Schreibers, recommended him to Coenraad Jacob Temminck, director of the Rijksmuseum van Natuurlijke Historie, natural history museum of Leiden, who was seeking an ...

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] |

Cenderawasih Bay
Cenderawasih Bay (, "Bird of Paradise Bay"), also known as Sarera Bay () and formerly Geelvink Bay (), is a large bay in northern Province of Papua, Central Papua and West Papua, New Guinea, Indonesia. Geography ''Cenderawasih Bay'' is a large bay to the northwest of the Indonesian province of Papua, north of the province of Central Papua, and east of the province of West Papua, between the Bird's Head Peninsula and the mouth of the Mamberamo River. The bay is more than 300 kilometers wide. The coastline from Manokwari, in the northwest of the bay, to Cape d'Urville at the mouth of the Mamberamo is more than 700 kilometers long. To the south, the Wandammen Peninsula heads north into the bay. Important places along the coast are Manokwari, Ransiki, Wasior and Nabire. The Wamma River, Tabai River, Warenai River, and Wapoga River empty into the Bay. History The Dutch name of the bay was after the frigate ''De Geelvink'' with which Jacob Weyland sailed through t ...

Parrots Of Oceania
Parrots (Psittaciformes), also known as psittacines (), are birds with a strong curved beak, upright stance, and clawed feet. They are classified in four families that contain roughly 410 species in 101 genera, found mostly in tropical and subtropical regions. The four families are the Psittaculidae (Old World parrots), Psittacidae (African and New World parrots), Cacatuidae (cockatoos), and Strigopidae (New Zealand parrots). One-third of all parrot species are threatened by extinction, with a higher aggregate extinction risk ( IUCN Red List Index) than any other comparable bird group. Parrots have a generally pantropical distribution with several species inhabiting temperate regions as well. The greatest diversity of parrots is in South America and Australasia. Parrotsalong with ravens, crows, jays, and magpiesare among the most intelligent birds, and the ability of some species to imitate human speech enhances their popularity as pets. They form the most variably sized bird ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of The Biak–Numfoor Rain Forests
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Birds Of The Schouten Islands
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton.

More than half are passerine or "perching" birds. Birds have Bird wing, 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 Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest
A forest is an ecosystem characterized by a dense ecological community, community of trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a Canopy (biology), canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, ''Global Forest Resources Assessment (FRA), Global Forest Resources Assessment 2020'' found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the largest Terrestrial ecosystem, terrestrial ecosystems of Earth by area, and are found around the globe. 45 percent of forest land is in the Tropical forest, trop ...
