Green-backed White-eye
The green-backed white-eye (''Zosterops xanthochroa'') is a species of bird in the family Zosteropidae. It is also known as the New Caledonian white-eye. It is endemic to New Caledonia. Taxonomy The green-backed white-eye was described by George Robert Gray in 1858 from a specimen collected in Nu. The relationships between this species and other white-eyes are uncertain, but it may form a superspecies with the small Lifou white-eye, also from New Caledonia, the Fiji white-eye and the yellow-fronted white-eye (from Vanuatu). This speculative proposal is based upon the shared yellow underparts and their living in the same general region. Distribution and habitat The green-backed white-eye is endemic to the islands of New Caledonia, where it is found on Grande Terre, the main island, the smaller L'Île-des-Pins, as well as Maré in the Loyalty Islands. It is replaced on Lifou by the small and large Lifou white-eyes. It is primarily a bird of primary rainforest, from sea level up, ...

George Robert Gray
George Robert Gray FRS (8 July 1808 – 6 May 1872) was an English zoologist and author, and head of the ornithological section of the British Museum, now the Natural History Museum, in London for forty-one years. He was the younger brother of the zoologist John Edward Gray and the son of the botanist Samuel Frederick Gray. George Gray's most important publication was his ''Genera of Birds'' (1844–49), illustrated by David William Mitchell and Joseph Wolf, which included 46,000 references. Biography He was born in Little Chelsea, London, to Samuel Frederick Gray, naturalist and pharmacologist, and Elizabeth (née Forfeit), his wife. He was educated at Merchant Taylor's School. Gray started at the British Museum as Assistant Keeper of the Zoology Branch in 1831. He began by cataloguing insects, and published an ''Entomology of Australia'' (1833) and contributed the entomogical section to an English edition of Georges Cuvier's ''Animal Kingdom''.

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

Birds Described In 1859
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. Birds ...

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 white-ey ...

Barn Owl
The barn owl (''Tyto alba'') is the most widely distributed species of owl in the world and one of the most widespread of all species of birds, being found almost everywhere except for the polar and desert regions, Asia north of the Himalayas, most of Indonesia, and some Pacific Islands. It is also known as the common barn owl, to distinguish it from the other species in its family, Tytonidae, which forms one of the two main lineages of living owls, the other being the typical owls (''Strigidae''). There are at least three major lineages of barn owl: the western barn owl of Europe, western Asia, and Africa; the eastern barn owl of southeastern Asia and Australasia; and the American barn owl of the Americas. Some taxonomic authorities classify barn owls differently, recognising up to five separate species; and further research needs to be done to resolve the disparate taxonomies. There is considerable variation of size and colour among the approximately 28 subspecies, but most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-throated Parrotfinch
The red-throated parrotfinch (''Erythrura psittacea'') is a species of estrildid finch found in New Caledonia. It has an estimated global extent of occurrence of 20,000 to 50,000 km2. It is found in both subtropical or tropical moist lowland forest and shrubland habitats. The IUCN has classified the species as being of least concern. Taxonomy The red-throated parrotfinch was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the finches in the genus ''Fringilla'' and coined the binomial name ''Fringilla psittacea''. The specific epithet is Neo-Latin, Modern Latin for "parrot-like". Gmelin based his account on the "parrot finch" that had been described and illustrated in 1783 by the English ornithologist John Latham (ornithologist), John Latham in his multi-volume work ''A General Synopsis of Birds''. Latham's had access to a specimen that had been shot by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mixed Species Feeding Flock
A mixed-species feeding flock, also termed a mixed-species foraging flock, mixed hunting party or informally bird wave, is a flock of usually insectivorous birds of different species that join each other and move together while foraging. These are different from feeding aggregations, which are congregations of several species of bird at areas of high food availability. While it is currently unknown how mixed-species foraging flocks originate, researchers have proposed a few mechanisms for their initiation. Many believe that nuclear species play a vital role in mixed-species flock initiation. Additionally, the forest structure is hypothesized to play a vital role in these flocks' formation. In Sri Lanka, for example, vocal mimicry by the greater racket-tailed drongo might have a key role in the initiation of mixed-species foraging flocks, while in parts of the American tropics packs of foraging golden-crowned warblers might play the same role.

Lantana
''Lantana'' () is a genus of about 150 species of perennial flowering plants in the verbena family, Verbenaceae. They are native to tropical regions of the Americas and Africa but exist as an introduced species in numerous areas, especially in the Australian-Pacific region, South and Northeastern part of India. The genus includes both herbaceous plants and shrubs growing to tall. Their common names are shrub verbenas or lantanas. The generic name originated in Late Latin, where it refers to the unrelated ''Viburnum lantana''. Lantana's aromatic flower clusters (called umbels) are a mix of red, orange, yellow, or blue and white florets. Other colors exist as new varieties are being selected. The flowers typically change color as they mature, resulting in inflorescences that are two- or three-colored. "Wild lantanas" are plants of the unrelated genus ''Abronia'', usually called "sand-verbenas". Ecology Some species are invasive, and are considered to be noxious weeds, such a ...

Papaya
The papaya (, ), papaw, () or pawpaw () is the plant species ''Carica papaya'', one of the 21 accepted species in the genus ''Carica'' of the family Caricaceae. It was first domesticated in Mesoamerica, within modern-day southern Mexico and Central America. In 2020, India produced 43% of the world supply of papayas. Etymology The word ''papaya'' comes from Arawak via Spanish, this is also where ''papaw'' and ''pawpaw'' come from. Description The papaya is a small, sparsely branched tree, usually with a single stem growing from tall, with spirally arranged leaves confined to the top of the trunk. The lower trunk is conspicuously scarred where leaves and fruit were borne. The leaves are large, in diameter, deeply palmately lobed, with seven lobes. All parts of the plant contain latex in articulated laticifers. Flowers Papayas are dioecious. The flowers are five-parted and highly dimorphic; the male flowers have the stamens fused to the petals. The female flowers h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
