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; and the Caroline Islands, including Yap, Chuuk, Pohnpei, Kosrae, and Palau. The Marianas subspecies, ''Myzomela rubrata saffordi'', is now extirpated from Guam since 1986. 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 feeds ...

Saipan
Saipan () is the largest island and capital of the Northern Mariana Islands, an unincorporated Territories of the United States, territory 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. Its people have been United States citizens since the 1980s. Saipan is one of the main homes of the Chamorro people, Chamorro, the Indigenous peoples of Oceania, indigenous people of the Mariana Islands. Saipan has been inhabited for over four thousand years. From the 17th century, the island experienced Spanish Empire#Pacific exploration and trade, Spanish occupation and rule until the Spanish–American War of 1898, when Saipan was briefly occupied by the United States, before being German–Spanish Treaty (1899), formally sold German New Guinea#Imperial German Pacific protectorates, to Germany. About 15 years of German rule were South Seas Mandate, followed by 30 years of Empire of Japan, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Local Extinction
Local extinction, also extirpation, is the termination of a species (or other taxon) in a chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with extinction, global extinctions. Local extinctions mark a change in the ecology of an area. It has sometimes been followed by a replacement of the species taken from other locations, such as with wolf reintroduction. Discussion Glacial period, Glaciation is one factor that leads to local extinction. This was the case during the Quaternary glaciation, Pleistocene glaciation event in North America. During this period, most of the native North American species of earthworm were killed in places covered by glaciation. This left them open for colonization by European earthworms brought over in soil from Europe. Species naturally become extinct from islands over time; this can be either local extinction if the species also occurs elsewhere, or in cases of endemism, island endemism, outright ex ...

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 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 further ...

Myzomela
''Myzomela'' is a genus of bird in the honeyeater family Meliphagidae. It is the largest genus of honeyeaters, with 40 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. Several species are named for the islands they were discovered or live on. The genus was introduced by the naturalists Nicholas Aylward Vigors, Nicholas Vigors and Thomas Horsfield in 1827 with ''Meliphaga cardinalis'' as the type species. This is a junior synonym of ''Certhia sanguinolenta'' John Latham (ornithologist), Latham, 1801, the scarlet myzomela. The genus contains the following 41 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'') * ...

Pollinator
A pollinator is an animal that moves pollen from the male anther of a flower to the female carpel, 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 Aculeata, 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, Phalangeriformes, 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 s ...

Bridled White-eye
The bridled white-eye (''Zosterops conspicillatus'') ( Chamorro name: ''nosa'') is a species of white-eye native to the Mariana Islands and formerly Guam. The species' natural habitat is tropical forests, shrublands and urban areas. Taxonomy Some sources, such as the IUCN, split the nominate subspecies and ''Z. c. saypani'' into separate species; in that case, the latter is known by the common name Saipan white-eye. Formerly, the Rota white-eye (''Zosterops rotensis'') was also considered as a subspecies of the bridled white-eye. Conservation The nominate subspecies ''Zosterops conspicillatus conspicillatus'', endemic to the island of Guam, became extinct due to the introduction of the brown tree snake. The last known sighting was in 1983. The US Fish and Wildlife Service delisted the species from the Endangered Species Act in October 2023 citing extinction. The remaining subspecies, ''Z. conspicillatus saypani'', endemic to the Northern Mariana Islands, on the islands of Tin ...

Territory (animal)
In ethology, territory is the sociographical area that an animal consistently defends against conspecificity, conspecific competition (biology), 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 defendin ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Nectar
Nectar is a viscous, sugar-rich liquid produced by Plant, plants in glands called nectaries, either within the flowers with which it attracts pollination, pollinating animals, or by extrafloral nectaries, which provide a nutrient source to animal Mutualism (biology), mutualists, which in turn provide plant defense against herbivory#Indirect defenses, herbivore protection. Common nectar-consuming pollinators include mosquitoes, hoverfly, hoverflies, wasps, bees, butterfly, butterflies and moths, hummingbirds, honeyeaters and Bat#Fruit and nectar, bats. 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 predacious or Parasitoid wasp, parasitoid wasps (e.g., the social wasp species ''Apoica flavissima'') rely on nectar as a primary food source. In turn, these wasps then hunt agricultural pest insects as food ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Habitat
In ecology, habitat refers to the array of resources, 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 Biophysical environment, 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 Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
