Nectarinia Souimanga
The souimanga sunbird (''Cinnyris sovimanga'') is a small passerine bird of the sunbird family, Nectariniidae. It is native to the islands of the western Indian Ocean where it occurs on Madagascar, the Aldabra Group and the Glorioso Islands. Taxonomy The souimanga sunbird was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the tree-creepers in the genus ''Certhia'' and coined the binomial name ''Certhia sovimanga''. The specific epithet ''sovimanga'' comes from a French name for the bird, ''Souï-manga''. Gmelin based his account on "Le grimpereau violet de Madagascar" that had been described and illustrated in 1760 by the French zoologist Mathurin Jacques Brisson and ''Le Soui-Manga'' that had been described in 1778 by the Comte de Buffon. The souimanga sunbird is now placed in the large genus ''Cinnyris'' that was introduced in 1816 by the French naturalist G ...

Cinnyris
''Cinnyris'' is a genus of sunbirds. Its members are sometimes included in ''Nectarinia''. They are generally known as double-collared sunbirds because the fringe of their bib usually includes a band of contrastingly coloured feathers. The sunbirds are a group of very small Old World passerine birds which feed largely on nectar, although they will also take insects, especially when feeding young. Flight is fast and direct on their short wings. Most species can take nectar by hovering like a hummingbird, but usually perch to feed. Taxonomy The genus ''Cinnyris'' was introduced by the French naturalist Georges Cuvier in 1816. The type species was designated as "''Certhia splendida'' George Shaw (biologist), Shaw" by George Robert Gray in 1855. This taxon is a junior synonym of ''Certhia coccinigaster'' described by John Latham (ornithologist), John Latham in 1801. This is now the splendid sunbird. The name ''Cinnyris'' is from the Ancient Greek κιννυρις (''kinnyris''), an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eclipse Plumage
Plumage () is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morphs. The placement of feathers on a bird is not haphazard but rather emerges in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month or so later givi ...

Nominate Subspecies
In biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics ( morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks.

Male
Male (Planet symbols, symbol: ♂) is the sex of an organism that produces the gamete (sex cell) known as sperm, which fuses with the larger female gamete, or Egg cell, ovum, in the process of fertilisation. A male organism cannot sexual reproduction, reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and Asexual reproduction, asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs. In humans, the word ''male'' can also be used to refer to gender, in the social sense of gender role or gender identity. Overview The existence of separate sexes has evolved independently at different times and in different lineage (evolution), lineages, an example of convergent evolution. The repeated pattern is sexual reproduction in isogamy, isogamous species with two or more mating types with gametes of identic ...

Beak
The beak, bill, or rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs and a few mammals. A beak is used for pecking, grasping, and holding (in probing for food, eating, manipulating and carrying objects, killing prey, or fighting), preening, courtship, and feeding young. The terms ''beak'' and '' rostrum'' are also used to refer to a similar mouth part in some ornithischians, pterosaurs, cetaceans, dicynodonts, rhynchosaurs, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a bill-like structure), sirens, pufferfish, billfishes, and cephalopods. Although beaks vary significantly in size, shape, color and texture, they share a similar underlying structure. Two bony projections–the upper and lower mandibles–are covered with a thin keratinized layer of epidermis known as the rhamphotheca. In most species, two holes called ''nares'' lead to the respiratory system. Etymology Although the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astove Atoll
Astove Atoll is a large atoll, part of the Aldabra Group, lying in the Outer Islands of Seychelles, southwest of the capital, Victoria, on Mahé Island. Alphonse Fishing Company and Blue Safari Seychelles operate from the atoll, offering packages to sustainably fly-fish and dive the Astove Wall. History The name Astove is said to be derived from the Portuguese ''As Doze'' Island, meaning the twelve islands, which may have been the original Portuguese name for Farquhar. Much of the region in which Astove lies was explored by Arab seamen and merchants between 1000 and 1500 AD, but there is no record of human settlement on the island before 1760. In that year, the Portuguese frigate ''La Dom Royal'', laden with plunder and slaves, went aground at Astove. All aboard made it to the island, but the captain and crew soon abandoned Astove and struck out for Mozambique in a long boat. They never returned for the slaves, who organized into a community and subsisted on the bounty of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cosmoledo
Cosmoledo Atoll is an atoll of the Aldabra Group and belongs to the Outer Islands of the Seychelles, and is located southwest of the capital, Victoria, on Mahé Island. History The name ''Cosmoledo'' honours António (or Antão) Gonçalves Cosme Ledo who sailed to India in 1537 as pilot of the vessel Flor de la Mar, becoming patron chief before returning to Portugal in 1545 aboard the São Joao. Menai and Wizard Islands were named after ships that explored the atoll on the Moresby Expedition in 1822. In 1878, Sergeant Rivers visited the atoll and reported that judging by the turtle remains on the beach, the atoll was frequently visited by fishermen and whalers. He found a recently destroyed hut and ‘turtle park’ on Menai; a hut on the southern point of Wizard built from the wreckage of the ''Merry Monarch'' (wrecked in April 1874), which had been burnt. He reported that Menai was virtually covered with tall mangroves. Cosmoledo was settled shortly after this and a visito ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Assumption Island
Assumption Island is a small island in the Outer Islands of Seychelles north of Madagascar, southwest of the capital, Victoria. In 2018, Seychelles and India signed an agreement to build and operate a joint military facility on a portion of the island. The Seychelles National Assembly refuted the agreement after protests by the citizens. As protests continued, the Seychellois president endorsed the Assumption Island deal with India. The plan caused public protests by activists who believed that the islands should stay out of the brewing India-China regional conflict. The agreement was declared "''dead''" by the Island's opposition party. History Assumption Island was discovered by Captain Nicolas Morphey on 14 August 1756, and was named after the religious feast of the next day. In 1908, the island was leased to Mr H. Savy of Mahé, who built a coconut plantation there. The first settlement was in the northern part of the island. During a visit two years later, he realiz ...

Aldabra
Aldabra, the world's second-largest coral atoll (the largest is Kiritimati), is located east of the continent of Africa. It is part of the Aldabra Group of islands in the Indian Ocean that are part of the Outer Islands (Seychelles), Outer Islands of the Seychelles, with a distance of 1,120 km (700 mi) southwest of the capital, Victoria, Seychelles, Victoria on Mahé, Seychelles, Mahé Island. Initially named by Arab seafarers for its harsh environment, Aldabra became a French colonial empire, French colony dependency in the 18th century, leading to the exploitation of its natural resources, particularly giant tortoises. After passing through British hands, Aldabra faced potential military use in the 1960s, but international protests resulted in its protection. The atoll boasts unique geography, featuring the world's largest raised coral reef and a large shallow lagoon. Aldabra's history involves human impact, including failed agricultural ventures.

Robert Ridgway
Robert Ridgway (July 2, 1850 – March 25, 1929) was an American ornithologist specializing in systematics. He was appointed in 1880 by Spencer Fullerton Baird, secretary of the Smithsonian Institution, to be the first full-time curator of birds at the United States National Museum, a title he held until his death. In 1883, he helped found the American Ornithologists' Union, where he served as officer and journal editor. Ridgway was an outstanding descriptive taxonomist, capping his life work with ''The Birds of North and Middle America'' (eight volumes, 1901–1919). In his lifetime, he was unmatched in the number of North American bird species that he species description, described for science. As technical illustrator, Ridgway used his own paintings and outline drawings to complement his writing. He also published two books that systematized color names for describing birds, ''A Nomenclature of Colors for Naturalists'' (1886) and ''Color Standards and Color Nomenclature'' ...
