Micronesian Myzomela
The Micronesian myzomela (''Myzomela rubratra'') is a species of bird in the honeyeater family Meliphagidae. The species forms a superspecies with a number of related and similar looking island and mainland myzomelas across the Pacific and Australasia. It in turn is composed of seven insular subspecies. It is distributed throughout the Northern Mariana Islands, including Rota, Tinian and Saipan, as well as Yap, Chuuk, Pohnpei and Kosrae in Micronesia, and the islands of Palau. The species once also occurred in Guam, but that population is now almost certainly extinct. Across its wide distribution, the Micronesian myzomela occupies a range of natural and man-made habitats, from sea level to the highest peaks, although the lack of mountains in Micronesia predominantly makes this a species of the lowlands. Forests, mangroves, scrubland, secondary scrub, savanna, as well as agricultural, plantation and urban areas, are all used by this species. The Micronesian myzomela primarily f ...

Saipan
Saipan ( ch, Sa’ipan, cal, Seipél, formerly in es, Saipán, and in ja, 彩帆島, Saipan-tō) is the largest island of the Northern Mariana Islands, a Commonwealth (U.S. insular area), commonwealth of the United States in the western Pacific Ocean. According to 2020 estimates by the United States Census Bureau, the population of Saipan was 43,385, a decline of 10% from its 2010 count of 48,220. The legislative and executive branches of Commonwealth government are located in the village of Capitol Hill, Saipan, Capitol Hill on the island while the judicial branch is headquartered in the village of Susupe. Since the entire island is organized as a single municipality, most publications designate Saipan as the Commonwealth's capital. As of 2015, Saipan's mayor is David M. Apatang and the governor of the Northern Mariana Islands is Ralph Torres. History Prehistory Traces of human settlements on Saipan have been found by archaeologists ranging over 4,000 years, includ ...

Palau
Palau,, officially the Republic of Palau and historically ''Belau'', ''Palaos'' or ''Pelew'', is an island country and microstate in the western Pacific. The nation has approximately 340 islands and connects the western chain of the Caroline Islands with parts of the Federated States of Micronesia. It has a total area of . The most populous island is Koror, home to the country's most populous city of the same name. The capital Ngerulmud is located on the nearby island of Babeldaob, in Melekeok State. Palau shares maritime boundaries with international waters to the north, the Federated States of Micronesia to the east, Indonesia to the south, and the Philippines to the northwest. The country was originally settled approximately 3,000 years ago by migrants from Maritime Southeast Asia. Palau was first drawn on a European map by the Czech missionary Paul Klein based on a description given by a group of Palauans shipwrecked on the Philippine coast on Samar. Palau islands ...

Birds Of Micronesia
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myzomela
''Myzomela'' is a genus of bird in the honeyeater family Meliphagidae. It is the largest genus of honeyeaters, with 39 species, and the most geographically widespread. It ranges from Indonesia to Australia and into the islands of the Pacific Ocean as far as Micronesia and Samoa. The genus was introduced by the naturalists Nicholas Vigors and Thomas Horsfield in 1827. The type species is the scarlet myzomela (''Myzomela sanguinolenta''). The title page is dated 1826. The genus contains the following 40 species: * Drab myzomela (''Myzomela blasii'') * White-chinned myzomela (''Myzomela albigula'') * Ashy myzomela (''Myzomela cineracea'') * Ruby-throated myzomela (''Myzomela eques'') *Moluccan myzomela (''Myzomela simplex'') * Red-tinged myzomela (''Myzomela rubrotincta'') *Biak myzomela (''Myzomela rubrobrunnea'') * Dusky myzomela (''Myzomela obscura'') * Red myzomela (''Myzomela cruentata'') *Reddish myzomela (''Myzomela erythrina'') * Papuan black myzomela (''Myzomela nigr ...

Pollinator
A pollinator is an animal that moves pollen from the male anther of a flower to the female stigma of a flower. This helps to bring about fertilization of the ovules in the flower by the male gametes from the pollen grains. Insects are the major pollinators of most plants, and insect pollinators include all families of bees and most families of aculeate wasps; ants; many families of flies; many lepidopterans (both butterflies and moths); and many families of beetles. Vertebrates, mainly bats and birds, but also some non-bat mammals (monkeys, lemurs, possums, rodents) and some lizards pollinate certain plants. Among the pollinating birds are hummingbirds, honeyeaters and sunbirds with long beaks; they pollinate a number of deep-throated flowers. Humans may also carry out artificial pollination. A pollinator is different from a pollenizer, a plant that is a source of pollen for the pollination process. Background Plants fall into pollination syndromes that reflect the type o ...

Bridled White-eye
The bridled white-eye (''Zosterops conspicillatus'') (Chamorro name: ''nosa'') was a species of bird in the family Zosteropidae. It was endemic to the island of Guam in the Mariana Islands. The species' natural habitat was subtropical or tropical moist lowland forests. One traditionally recognized subspecies is endemic to the Northern Mariana Islands, on the islands of Tinian, Saipan and Aguijan. The nominate subspecies formerly occurred on the island of Guam, but is now considered extinct due to the invasive and predatory brown tree snake. The last known sighting was in 1983. The remaining subspecies, ''Z. (c.) saypani'', is separated as a full-species by some authorities. Until recently, this population was extremely abundant across its native range. 2007-2008 surveys estimated a population of 620,000-940,000, with approximately 534,000 birds on Saipan alone. In 2010, this species was the second most abundant breeding landbird encountered by surveyors on Saipan. The potential i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Territory (animal)
In ethology, territory is the sociographical area that an animal consistently defends against conspecific competition (or, occasionally, against animals of other species) using agonistic behaviors or (less commonly) real physical aggression. Animals that actively defend territories in this way are referred to as being territorial or displaying territorialism. Territoriality is only shown by a minority of species. More commonly, an individual or a group of animals occupies an area that it habitually uses but does not necessarily defend; this is called its home range. The home ranges of different groups of animals often overlap, and in these overlap areas the groups tend to avoid each other rather than seeking to confront and expel each other. Within the home range there may be a ''core area'' that no other individual group uses, but, again, this is as a result of avoidance. Function The ultimate function of animals inhabiting and defending a territory is to increase the indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nectar
Nectar is a sugar-rich liquid produced by plants in glands called nectaries or nectarines, either within the flowers with which it attracts pollinating animals, or by extrafloral nectaries, which provide a nutrient source to animal mutualists, which in turn provide herbivore protection. Common nectar-consuming pollinators include mosquitoes, hoverflies, wasps, bees, butterflies and moths, hummingbirds, honeyeaters and bats. Nectar plays a crucial role in the foraging economics and evolution of nectar-eating species; for example, nectar foraging behavior is largely responsible for the divergent evolution of the African honey bee, ''A. m. scutellata'' and the western honey bee. Nectar is an economically important substance as it is the sugar source for honey. It is also useful in agriculture and horticulture because the adult stages of some predatory insects feed on nectar. For example, a number of parasitoid wasps (e.g. the social wasp species ''Apoica flavissima'') rely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guam
Guam (; ch, Guåhan ) is an organized, unincorporated territory of the United States in the Micronesia subregion of the western Pacific Ocean. It is the westernmost point and territory of the United States (reckoned from the geographic center of the U.S.); its capital Hagåtña (144°45'00"E) lies further west than Melbourne, Australia (144°57'47"E). In Oceania, Guam is the largest and southernmost of the Mariana Islands and the largest island in Micronesia. Guam's capital is Hagåtña, and the most populous village is Dededo. People born on Guam are American citizens but have no vote in the United States presidential elections while residing on Guam and Guam delegates to the United States House of Representatives have no vote on the floor. Indigenous Guamanians are the Chamoru, historically known as the Chamorro, who are related to the Austronesian peoples of Indonesia, the Philippines, Malaysia, Taiwan, Micronesia, and Polynesia. As of 2022, Guam's population is 168, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micronesia
Micronesia (, ) is a subregion of Oceania, consisting of about 2,000 small islands in the western Pacific Ocean. It has a close shared cultural history with three other island regions: the Philippines to the west, Polynesia to the east, and Melanesia to the south—as well as with the wider community of Austronesian peoples. The region has a tropical marine climate and is part of the Oceanian realm. It includes four main archipelagos—the Caroline Islands, the Gilbert Islands, the Mariana Islands, and the Marshall Islands—as well as numerous islands that are not part of any archipelago. Political control of areas within Micronesia varies depending on the island, and is distributed among six sovereign nations. Some of the Caroline Islands are part of the Republic of Palau and some are part of the Federated States of Micronesia (often shortened to "FSM" or "Micronesia"—not to be confused with the identical name for the overall region). The Gilbert Islands (along with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
