Grey-green Fruit Dove
The grey-green fruit dove (''Ptilinopus purpuratus'') is a species of bird in the family Columbidae. It is endemic to the Society Islands in French Polynesia. Its natural habitat is subtropical or tropical moist lowland forests. Taxonomy The grey-green fruit dove 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 all the other doves and pigeons in the genus ''Columba'' and coined the binomial name ''Columba purpurata''. Gmelin's description was based on the "purple-crowned pigeon" from Otaheite (now Tahiti) that had been described in 1783 by English ornithologist John Latham in his ''A General Synopsis of Birds''. The grey-green fruit dove is now placed with nearly 60 other fruit doves in the genus '' Ptilinopus'' that was introduced in 1825 by the English naturalist William John Swainson. The genus name combines the Ancient Greek meaning "feather" with m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

William John Swainson
William John Swainson FLS, FRS (8 October 1789 – 6 December 1855), was an English ornithologist, malacologist, conchologist, entomologist and artist. Life Swainson was born in Dover Place, St Mary Newington, London, the eldest son of John Timothy Swainson the Second (1756–1824), an original fellow of the Linnean Society. He was cousin of the amateur botanist Isaac Swainson.Etymologisches Worterbuch der botanischen Pflanzennamen by H. Genaust. Review by Paul A. Fryxell ''Taxon'', Vol. 38(2), 245–246 (1989). His father's family originated in Lancashire, and both grandfather and father held high posts in Her Majesty's Customs, the father becoming Collector at Liverpool.

Atoll Fruit Dove
The atoll fruit dove (''Ptilinopus coralensis'') is a species of bird in the family Columbidae. It is endemic to the Tuamotu archipelago in French Polynesia. Its natural habitats are subtropical or tropical moist lowland forests and plantations. It is threatened by habitat loss. Distribution and population The atoll fruit dove is widespread throughout the islands of the Tuamotu Archipelago, French Polynesia. In a 1999 survey it was found to be uncommon on five out of eight islands visited, but others have found it to be abundant on some atolls which have remained free from the ravages of introduced predators. Ecology The atoll fruit dove is the world's only dove in the tropical Pacific that has adapted exclusively to low coral atolls. It lives in forests and abandoned coconut plantations. It mainly feeds on insects and seeds, usually on the ground. This species also eats the leaves of the " tafano" or " kahaia" (''Guettarda speciosa'' ) trees with odorous flowers. Threats ...

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 eating, preening, manipulating objects, killing prey, fighting, probing for food, 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, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a beak-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 word "beak" was, in the past, generally restricted to the sharpened bills o ...

Hectare
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), or 10,000 m2, and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare ("hecto-" + "are") was thus 100 ''ares'' or km2 (10,000 square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa (1,000 m2) and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, i ...

Mo'orea
Moorea ( or ; Tahitian: ), also spelled Moorea, is a volcanic island in French Polynesia. It is one of the Windward Islands, a group that is part of the Society Islands, northwest of Tahiti. The name comes from the Tahitian word , meaning "yellow lizard": = lizard ; (from ) = yellow. An older name for the island is ', sometimes spelled or (among other spellings that were used by early visitors before Tahitian spelling was standardized). Early Western colonists and voyagers also referred to Moorea as ''York Island'' or ''Santo Domingo''. History Prehistory According to recent archaeological evidence, the Society Islands were probably settled from Samoa and Tonga around 200 CE.Patrick V.

International Ornithologists' Union
The International Ornithologists' Union, formerly known as the International Ornithological Committee, is a group of about 200 international ornithologists, and is responsible for the International Ornithological Congress and other international ornithological activities, undertaken by its standing committees.

Raiatea
Raiatea or Ra'iatea ( Tahitian: ''Ra‘iātea'') is the second largest of the Society Islands, after Tahiti, in French Polynesia. The island is widely regarded as the "centre" of the eastern islands in ancient Polynesia and it is likely that the organised migrations to the Hawaiian Islands, New Zealand and other parts of East Polynesia started at Raiatea. A traditional name for the island is Havai'i, homeland of the Māori people. Situated on the southeast coast is the historical Taputapuatea marae, which was established by 1000 CE. The site was the political and religious center of eastern Polynesia for several centuries, and was inscribed on the UNESCO World Heritage List in 2017 for its historical significance. The main township on Raiatea is Uturoa, the administrative centre for the Leeward Islands (French ''Îles Sous-le-vent''). There are also colleges which serve as the main educational location for secondary schools for students from the regional islands of Bora Bor ...

Raiatea Fruit-dove
The Raiatea fruit dove (''Ptilinopus chrysogaster'') is a species of bird in the family Columbidae. It is endemic to the Society Islands in French Polynesia. Although first named to science in 1853, this fruit dove was evidently discovered 30 years earlier, by René Primevère Lesson (1794–1849), while serving as naturalist aboard La Coquille. It was formerly considered a subspecies of the grey-green fruit dove but was split as a distinct species by the IOC in 2021. Its natural habitat is subtropical or tropical moist lowland forests. Distribution and population The Raiatea fruit dove is endemic to the French Polynesian islands Huahine, Raiatea, Tahaa, Bora Bora, and, at least formerly, Maupiti. There is an estimated population of p 1000 to 2500 mature individual birds. Better population estimates after 2001 are unknown. Threats There is an ongoing population decline due to habitat destruction; the introduction of non-native plants, predation by invasive species such as ...

Polynesia
Polynesia () "many" and νῆσος () "island"), to, Polinisia; mi, Porinihia; haw, Polenekia; fj, Polinisia; sm, Polenisia; rar, Porinetia; ty, Pōrīnetia; tvl, Polenisia; tkl, Polenihia (, ) is a subregion of Oceania, made up of more than 1,000 islands scattered over the central and southern Pacific Ocean. The indigenous people who inhabit the islands of Polynesia are called Polynesians. They have many things in common, including language relatedness, cultural practices, and traditional beliefs. In centuries past, they had a strong shared tradition of sailing and using stars to navigate at night. The largest country in Polynesia is New Zealand. The term was first used in 1756 by the French writer Charles de Brosses, who originally applied it to all the islands of the Pacific. In 1831, Jules Dumont d'Urville proposed a narrower definition during a lecture at the Geographical Society of Paris. By tradition, the islands located in the southern Pacific have also ...
