Green-fronted White-eye
The green-fronted white-eye (''Zosterops minor'') is a songbird species. It is closely related to the Old World babblers, and its family Zosteropidae might better be included in the Tiimalidae. Some sources include this species within ''Z. atrifrons'', the black-crowned white-eye. The black-fronted white-eye (''Z. chrysolaemus'') was formerly considered a subspecies, and until it was split as a distinct species, the name "black-fronted white-eye" was also used for ''Z. minor''. It is found in New Guinea and offshore islands. Quite common, it is not considered a threatened species Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of '' critical depen ... by the IUCN.

Adolf Bernard Meyer
Adolf Bernhard Meyer (11 October 1840, Hamburg – 22 August 1911, Dresden) was a German anthropologist, ornithologist, entomologist, and herpetologist. He served for nearly thirty years as director of the Königlich Zoologisches und Anthropologisch-Ethnographisches Museum (now the natural history museum or Museum für Tierkunde Dresden) in Dresden. He worked on comparative anatomy and appreciated the ideas of evolution, and influenced many German scientists by translating into German the 1858 papers by Darwin and Wallace which first proposed evolution by natural selection. Influenced by the writings of Wallace with whom he interacted, he travelled to Southeast Asia, and collected specimens and recorded his observations from the region. Biography Meyer was born in a wealthy Jewish family in Hamburg as Aron Baruch Meyer, and was educated at the universities of Göttingen, Vienna, Zürich and Berlin. He became director of the Anthropological and Ethnographic Museum in Dresden in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Songbird
A songbird is a bird belonging to the suborder Passeri of the perching birds (Passeriformes). Another name that is sometimes seen as the scientific or vernacular name is Oscines, from Latin ''oscen'', "songbird". The Passeriformes contains 5000 or so speciesEdwards, Scott V. and John Harshman. 2013. Passeriformes. Perching Birds, Passerine Birds.

Songbirds form one of the two major lineages of extant perching birds (~4000 species), the other being the Tyranni (~1000 species), which are most diverse in the Neotropics and absent from many parts of the world. The Tyranni have a simpler syrinx musculature, and while their vocalizations are often just as complex and striking as those ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old World Babbler
The Old World babblers or Timaliidae are a family of mostly Old World passerine birds. They are rather diverse in size and coloration, but are characterised by soft fluffy plumage. These are birds of tropical areas, with the greatest variety in Southeast Asia and the Indian subcontinent. The timaliids are one of two unrelated groups of birds known as babblers, the other being the Australasian babblers of the family Pomatostomidae (also known as pseudo-babblers). Morphological diversity is rather high; most species resemble "warblers", jays or thrushes. This group is among those Old World bird families with the highest number of species still being discovered. Characteristics Timaliids are small to medium birds. They have strong legs, and many are quite terrestrial. They typically have generalised bills, similar to those of a thrush or warbler, except for the scimitar babblers which, as their name implies, have strongly decurved bills. Most have predominantly brown plumage, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opin ...

Zosteropidae
The white-eyes are a family, Zosteropidae, of small passerine birds native to tropical, subtropical and temperate Sub-Saharan Africa, southern and eastern Asia, and Australasia. White-eyes inhabit most tropical islands in the Indian Ocean, the western Pacific Ocean, and the Gulf of Guinea. Discounting some widespread members of the genus ''Zosterops'', most species are endemic to single islands or archipelagos. The silvereye, ''Zosterops lateralis'', naturally colonised New Zealand, where it is known as the "wax-eye" or ''tauhou'' ("stranger"), from 1855. The silvereye has also been introduced to the Society Islands in French Polynesia, while the Japanese white-eye has been introduced to Hawaii. Characteristics White-eyes are mostly of undistinguished appearance, the plumage being generally greenish olive above, and pale grey below. Some species have a white or bright yellow throat, breast or lower parts, and several have buff flanks. As their common name implies, many specie ...

Black-crowned White-eye
The black-crowned white-eye (''Zosterops atrifrons'') is a songbird species. It is closely related to the Old World babblers, and its family Zosteropidae might better be included in the Tiimalidae. Its subspecies from the Sulawesi region might warrant recognition as distinct species ''Z. subatrifrons''. The Sangihe white-eye (''Z. nehrkorni'') and the Seram white-eye (''Z. stalkeri'') were formerly included in ''Z. atrifrons'', as is still, on occasion, the black-fronted white-eye (''Z. minor''). It is endemic to Indonesia. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. Quite common, it is not considered a threatened species Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future.

New Guinea
New Guinea (; Hiri Motu: ''Niu Gini''; id, Papua, or , historically ) is the world's second-largest island with an area of . Located in Oceania in the southwestern Pacific Ocean, the island is separated from Australia by the wide Torres Strait, though both landmasses lie on the same continental shelf. Numerous smaller islands are located to the west and east. The eastern half of the island is the major land mass of the independent state of Papua New Guinea. The western half, known as Western New Guinea, forms a part of Indonesia and is organized as the provinces of Papua, Central Papua, Highland Papua, South Papua, Southwest Papua, and West Papua. The largest cities on the island are Jayapura (capital of Papua, Indonesia) and Port Moresby (capital of Papua New Guinea). Names The island has been known by various names: The name ''Papua'' was used to refer to parts of the island before contact with the West. Its etymology is unclear; one theory states that ...

Threatened Species
Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of '' critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species * Endangered species * Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species which have not been evaluated (NE), or do not have sufficient data ( data deficient) also are not consid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships.

Zosterops
''Zosterops'' (meaning "eye- girdle") is a genus of passerine birds containing the typical white-eyes in the white-eye family Zosteropidae. The genus has the largest number of species in the white-eye family. They occur in the Afrotropical, Indomalayan, and Australasian realms. Typical white-eyes have a length of between . Their most characteristic feature is a conspicuous white feather ring around the eye, though some species lack it. The species in this group vary in the structural adaptations of the tongue. The ''Zosterops'' 'griseotinctus''group is an example of a "great speciator" inhabiting a vast area and showing a remarkable morphological differentiation on islands, some of which maybe as close as apart. Systematics The genus ''Zosterops'' was introduced by the naturalists Nicholas Vigors and Thomas Horsfield in 1827. The name combines the Ancient Greek words ''zōstēros'' "belt" or "girdle" and ''ōpos'' "eye". The type species was designated as the Malagasy whit ...
