Henderson Reed Warbler
The Henderson reed warbler (''Acrocephalus taiti''), also known as the Henderson reed-warbler or the Henderson Island reed warbler, is a species of Old World warbler in the family Acrocephalidae. It is found only on Henderson Island, part of the Pitcairn Islands. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss. Taxonomy The Henderson reed warbler was described as ''Acrocephalus taiti'' by the Scottish ornithologist William Robert Ogilvie-Grant in 1913 on the basis of specimens collected from Henderson Island. Historically, the species was treated as being conspecific with the Pitcairn reed warbler, Rimatara reed warbler, and Cook reed warbler based on morphological similarities between the species. In 1992, the American ornithologist Gary Graves split the taxa into distinct species, citing differences in the pattern of leucistic plumage between the species. The name of the genus is derived from the Ancient Greek ''akros'' mea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Robert Ogilvie-Grant
William Robert Ogilvie-Grant (25 March 1863 – 26 July 1924) was a Scottish ornithologist. Early life and education Grant was born on 25 March 1863 as the second son of Capt. the Hon. George Henry Essex Ogilvy-Grant, of Easter Elchies, Craigellachie, Scotland, of the 42nd Regiment of Foot, 42nd Highlanders, sixth son of Francis Ogilvy-Grant, 6th Earl of Seafield, and daughter of Sir William Gordon-Cumming, 2nd Baronet.

Career In 1882 he became an Assistant at the Natural History Museum, London, Natural History Museum. He studied ichthyology under Albert C. L. G.

International Ornithologists' Union
The International Ornithologists' Union (IOU) is an international organization for the promotion of ornithology Ornithology, from Ancient Greek ὄρνις (''órnis''), meaning "bird", and -logy from λόγος (''lógos''), meaning "study", is a branch of zoology dedicated to the study of birds. Several aspects of ornithology differ from related discip .... It links basic and applied research and nurtures education and outreach activities. Specifically, the IOU organizes and funds global congresses on ornithology at regular intervals, sets up and supports commissions and committees on various aspects of avian biology and conservation, and initiates and backs other international ornithological activities with specific aims consistent with its own mission and goal. It discloses the names and professional affiliations of its members on its website to encourage international collaboration and networking. The IOU acts as the Ornithology Section of the International Union of Biologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1913
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 ...

Acrocephalus (bird)
The ''Acrocephalus'' warblers are small, insectivorous passerine birds belonging to the genus ''Acrocephalus''. Formerly in the paraphyletic Old World warbler assemblage, they are now separated as the namesake of the marsh and tree warbler family Acrocephalidae. They are sometimes called marsh warblers or reed warblers, but this invites confusion with marsh warbler and Eurasian reed warbler, reed warbler. These are rather drab brownish warblers usually associated with marshes or other wetlands. Some are streaked, others plain. Many species breeding in temperate regions are bird migration, migratory. This genus has heavily diversified into many species throughout islands across the tropical Pacific Ocean, Pacific. This in turn has led to many of the resulting insular Endemism, endemic species to become Endangered species, endangered. Several of these species (including all but one of the species endemic to the Mariana Islands, Marianas and two endemic to French Polynesia) have al ...

Xylosma Suaveolens
''Xylosma'' is a genus of flowering plants in the family Salicaceae. It contains around 100 species of evergreen shrubs and trees commonly known as brushhollies, xylosmas, or, more ambiguously, "logwoods". The generic name is derived from the Greek words ξύλον (''xylon''), meaning "wood, tree", and ὀσμή (''osmé''), meaning "smell", referring to the fragrant wood of some of the species. The Takhtajan system places it in the family Flacourtiaceae, which is considered defunct by the Angiosperm Phylogeny Group. Description The leaves are alternate, simple, entire or finely toothed, long. The flowers are small, yellowish, produced on racemes long, usually dioecious, and have a strong scent.

Pisonia Grandis
''Pisonia grandis'', the grand devil's-claws, is a species of flowering tree in the ''Bougainvillea'' family, Nyctaginaceae. Description The tree has broad, thin leaves, smooth bark and bears clusters of green sweet-smelling flowers that mature into sticky barbed seeds. Dispersal occurs when seeds stick to bird feathers. Vegetative reproduction frequently results when fallen branches sprout or basal shoots develop into new trees. Distribution ''Pisonia'' trees are distributed throughout the coral cays of the Indian and Pacific Oceans. The species often dominates mature coral cay vegetation, growing in dense, thick strands up to tall. ''Pisonia'' wood is rather weak and soft and decays rapidly when the trees fall. ''Pisonia'' forests are a common nesting site for seabirds. One of the best remaining ''Pisonia'' forests can be found on Palmyra Atoll. St. Pierre Island, Farquhar Group, was once covered by a ''Pisonia grandis'' forest. This forest disappeared after guano mini ...
