Christmas Island Frigatebird
The Christmas frigatebird (''Fregata andrewsi''), or Christmas Island frigatebird, is a seabird of the frigatebird family Fregatidae which is an endemic breeder to Christmas Island in the Indian Ocean. The Christmas frigatebird is a large lightly built seabird with brownish-black plumage, long narrow wings and a deeply forked tail. It has a wingspan of around . The male has an egg shaped white patch on his belly and a striking red gular sac which he inflates to attract a mate. The female is slightly larger than the male and has a white breast and belly. They feed on fish taken in flight from the ocean's surface (mostly flying fish), and sometimes indulge in kleptoparasitism, harassing other birds to force them to regurgitate their food. The species is listed as vulnerable by the International Union for Conservation of Nature. Taxonomy and systematics The Christmas frigatebird was once considered to belong to the species ''Fregata aquila'' but in 1914 the Australian ornithologist ...

Jakarta Bay
Jakarta Bay ( id, Teluk Jakarta) is a bay north of North Jakarta city. The Thousand Islands (Indonesia), Thousand Islands are located in Jakarta Bay. 13 rivers flow into the bay. The majority of the bay's coastal communities consist of people living below the Poverty threshold, poverty line, in conditions of poor sanitation. Nutrient inputs from agricultural pollution, agricultural runoff, industrial pollution, and wastewater have led to eutrophication, which in turn led to changes in the area's biodiversity. Harmful algal blooms have been observed. References External links TelukJakarta.net Bays of Indonesia Landforms of Jakarta {{jakarta-geo-stub ...

Charles William Andrews
Charles William Andrews (30 October 1866 – 25 May 1924) F.R.S., was a British palaeontologist whose career as a vertebrate paleontologist, both as a curator and in the field, was spent in the services of the British Museum, Department of Geology. Biography Andrews was born in Hampstead, Middlesex . A graduate of the University of London, Andrews was awarded an assistant's position at the British Museum, after a competitive exam, in 1892. His first concerns were with fossil birds, and he described '' Aepyornis titan'', the extinct "Elephant Bird" of Madagascar (1894). He noticed the connections among widely separated flightless rails of Mauritius, the Chatham Islands and New Zealand and deduced that their flightless character had been independently evolved on the spot. Alfred Nicholson Leeds' gifts to the British Museum of Jurassic marine reptiles from the Oxford Clay of Peterborough elicited his interest in plesiosaurs and other sea-reptiles which culminated in a catalo ...

Birds Of Christmas Island
The Birds of Christmas Island form a heterogeneous group of 162 species. There is a core group of 4 endemics that have evolved on the remote island in the eastern Indian Ocean for thousands of years, attended by a suite of regular migrants, opportunists and occasional visitors. Some 200 km from the nearest land, Java, Christmas Island was not occupied by humans until the late 19th century. It is now an Australian territory. The natural vegetation of most of the 140 km² island is rainforest, to which the endemic landbirds are adapted, while the seabirds have taken advantage of a breeding location which had no major natural predators. This list's taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) follow the conventions of ''The Clements Checklist of Birds of the World'', 2022 edition. The family accounts at the beginning of each heading reflect this taxonomy, as do the species counts in each fam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lesser Frigatebird
The lesser frigatebird (''Fregata ariel'') is a seabird of the frigatebird family Fregatidae. At around 75 cm (30 in) in length, it is the smallest species of frigatebird. It occurs over tropical and subtropical waters across the Indian and Pacific Oceans as well as off the Atlantic coast of Brazil. The lesser frigatebird is a lightly built seabird with brownish-black plumage, long narrow wings and a deeply forked tail. The male has a striking red gular sac which he inflates to attract a mate. The female is slightly larger than the male and has a white breast and belly. Frigatebirds feed on fish taken in flight from the ocean's surface (often flying fish), and sometimes indulge in kleptoparasitism, harassing other birds to force them to regurgitate their food. Taxonomy The lesser frigatebird was first described as ''Atagen ariel'' by the English zoologist George Gray in 1845 from a specimen collected on Raine Island, Queensland, Australia. The lesser frigatebird is one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Great Frigatebird
The great frigatebird (''Fregata minor'') is a large seabird in the frigatebird family. There are major nesting populations in the tropical Pacific (including the Galapagos Islands) and Indian Oceans, as well as a tiny population in the South Atlantic. The great frigatebird is a large and lightly built seabird up to 105 cm long with predominantly black plumage. The species exhibits sexual dimorphism; the female is larger than the adult male and has a white throat and breast, and the male's scapular feathers have a purple-green sheen. In the breeding season, the male is able to distend his striking red gular sac. The species feeds on fish taken in flight from the ocean's surface (mostly flying fish), and indulges in kleptoparasitism less frequently than other frigatebirds. They feed in pelagic waters within 80 km (50 mi) of their breeding colony or roosting areas. Taxonomy The great frigatebird was formally described in 1789 by the German naturalist Johann Friedr ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gregory Mathews
Gregory Macalister Mathews Order of the British Empire, CBE FRSE FZS FLS (10 September 1876 – 27 March 1949) was an Australian-born amateur ornithologist who spent most of his later life in England. Life He was born in Biamble, New South Wales, Biamble in New South Wales the son of Robert H. Mathews. He was educated at The King's School, Parramatta. Mathews made his fortune in mining shares, and moved to England in 1902. In 1910 he was elected a Fellow of the Royal Society of Edinburgh. His proposers were William Eagle Clarke, Ramsay Heatley Traquair, John Alexander Harvie-Brown and William Evans (naturalist), William Evans. Ornithology Mathews was a controversial figure in Australian ornithology. He was responsible for bringing trinomial nomenclature into local taxonomy, however he was regarded as an extreme splitter. He recognised large numbers of subspecies on scant evidence and few notes. The extinct Lord Howe Pigeon was described by Mathews in 1915, using a painting as ...

International Union For Conservation Of Nature
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. The organization is best known to the wider pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
