Iora
: ''For the international organization, see Indian Ocean Rim Association'' : ''For the Australian Aboriginal people of the Sydney region, see Eora'' The ioras are a small family, Aegithinidae, of four passerine bird species found in south and southeast Asia. The family is composed of a single genus, ''Aegithina''. They were formerly grouped with the leafbirds and fairy-bluebirds, in the family Irenidae. Taxonomy and systematics The genus ''Aegithina'' was introduced in 1816 by the French ornithologist Louis Jean Pierre Vieillot to accommodate the common iora. The genus name is from Ancient Greek ''aigithos'' or ''aiginthos'', a mythical bird mentioned by Aristotle and other classical authors. The common iora was described in 1758 and given the binomial name ''Motacilla tiphia'' by Carl Linnaeus, but there was a some confusion about the nature of bird Linnaeus was referring to. Early taxonomists considered it to variously be a warbler, flycatcher, finch or babbler. When G. R. Gray ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Ocean Rim Association
The Indian Ocean Rim Association (IORA), formerly known as the Indian Ocean Rim Initiative and the Indian Ocean Rim Association for Regional Cooperation (IOR-ARC), is an international organisation consisting of 23 states bordering the Indian Ocean. The IORA is a regional forum, tripartite in nature, bringing together representatives of Government, Business and Academia, for promoting co-operation and closer interaction among them. It is based on the principles of Open Regionalism for strengthening Economic Cooperation particularly on Trade Facilitation and Investment, Promotion as well as Social Development of the region. The Coordinating Secretariat of IORA is located at Ebene Cybercity, Mauritius, Ebene, Mauritius. Overview The organisation was first established as Indian Ocean Rim Initiative in Mauritius in March 1995 and formally launched on 6–7 March 1997 by the conclusion of a multilateral treaty known as the Charter of the Indian Ocean Rim Association for Regional Co-oper ...

Common Iora
The common iora (''Aegithina tiphia'') is a small passerine bird found across the tropical Indian subcontinent and Southeast Asia, with populations showing plumage variations, some of which are designated as subspecies. A species found in scrub and forest, it is easily detected from its loud whistles and the bright colours. During the breeding season, males display by fluffing up their feathers and spiral in the air appearing like a green, black, yellow, and white ball. Taxonomy In 1747 the English naturalist George Edwards included an illustration and a description of the common iora in the second volume of his ''A Natural History of Uncommon Birds''. He used the English name "The Green Indian Fly-Catcher". Edwards based his hand-coloured etching on a specimen that had been sent from Bengal to the silk-pattern designer and naturalist Joseph Dandridge in London. When in 1758 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the tenth edition, he placed the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bird
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. B ...

Green Iora
The green iora (''Aegithina viridissima'') is a species of bird in the family Aegithinidae. It is found in the Thai-Malay Peninsula, Sumatra and Borneo. Its habitats include lowland forests, secondary forest and mangrove forest. It is threatened by habitat loss, and the International Union for Conservation of Nature (IUCN) has assessed it as near-threatened. Taxonomy This species was described as ''Jora viridissima'' by Charles Lucien Bonaparte in 1850. Harry C. Oberholser described subspecies ''Aegithina viridissima thapsina'' from the Anamba Islands in 1917, noting its larger size and yellower plumage. These two subspecies are recognised by the IOC World Bird List, while ''Aegithina viridissima nesiotica'' described by Oberholser in 1912 is now included in the nominate subspecies. Description The green iora is long. The male has black lores and bright yellow "eyelids" (a broken eye-ring). The face and upperparts are dark olive. The wings are black, with two white wing-bars o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aegithina Nigrolutea
Marshall's iora (''Aegithina nigrolutea''), also known as the white-tailed iora, is a songbird in the genus ''Aegithina'' found in parts of India and Sri Lanka. Distribution and identification The status of the species has been debated and has only recently been given full species status.Wells, D.R., E.C. Dickinson & R.W.R.J. Dekker. (2003) Systematic notes on Asian birds. 34. A preliminary review of the Aegithinidae. Zool. Verh. Leiden 344, 12-ix.2003: 7-15. full text/ref>Rasmussen, P and J Anderton (2005) Birds of South Asia. The Ripley Guide. Lynx Edicions and Smithsonian Institution. Earlier suggestions have been that it was a Cline (population genetics), clinal variant of the common iora ''Aegithina tiphia''. The diagnostic features of the species are the short wing and tail; white edging to tertials converging broadly at the tip, versus tertial tips black to only narrowly white in ''tiphia'' and a smaller and shorter bill than ''tiphia'' from any part of India.
