Réunion Pink Pigeon
The Réunion pink pigeon (''Nesoenas mayeri duboisi'', but see below) is an extinct subspecies of pigeon that formerly lived on the Mascarene island of Réunion. It is known from the description of a rusty-red pigeon given by Dubois in 1674 and a single subfossil humerus that agrees with that of the pink pigeon of Mauritius in generic characteristics, except being slightly longer. Also, Dubois' reference to the bill being red at the base and the eyes being surrounded by a red ring suggest that this species was closely allied to the Mauritius taxon. Dubois' description was as follows: It is considered a subspecies of the pink pigeon. Its genus '' Nesoenas'' was often synonymized with ''Columba'' in the past, but more recently it has been synonymized with ''Streptopelia''. As the pink pigeon and the Malagasy turtle dove cannot be firmly placed in either of these two genera but apparently represent a distinct lineage that diverged early, probably from the ancestor of ''Streptop ...

Walter Rothschild, 2nd Baron Rothschild
Lionel Walter Rothschild, 2nd Baron Rothschild, Baron de Rothschild, (8 February 1868 – 27 August 1937) was a British banker, politician, zoology, zoologist, and soldier, who was a member of the Rothschild family. As a Zionist leader, he was presented with the Balfour Declaration, which pledged United Kingdom, British support for a Jewish national home in Palestine (region), Mandatory Palestine. Rothschild was the president of the Board of Deputies of British Jews from 1925 to 1926. Early life Walter Rothschild was born in London as the eldest son and heir of Emma Louise von Rothschild and Nathan Rothschild, 1st Baron Rothschild, an immensely wealthy financier of the international Rothschild financial dynasty and the first Jewish Peerage, peer in England. The eldest of three children, Walter was deemed to have delicate health and was educated at home. As a young man, he travelled in Europe, attending the University of Bonn for a year before entering Magdalene College, Cam ...

Réunion Ibis
The Réunion ibis or Réunion sacred ibis (''Threskiornis solitarius'') is an list of extinct birds, extinct species of ibis that was endemic to the volcanic island of Réunion in the Indian Ocean. The first subfossil remains were found in 1974, and the ibis was first scientifically described in 1987. Its closest relatives are the Malagasy sacred ibis, the African sacred ibis, and the straw-necked ibis. Travellers' accounts from the 17th and 18th centuries described a white bird on Réunion that flew with difficulty and preferred solitude, which was subsequently referred to as the "Réunion solitaire". In the mid 19th century, the old travellers' accounts were incorrectly assumed to refer to white relatives of the dodo, due to one account specifically mentioning dodos on the island, and because 17th-century paintings of white dodos had recently surfaced. However, no fossils referable to dodo-like birds were ever found on Réunion, and it was later questioned whether the painting ...

Birds Of Réunion
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 furth ...

Endemic Birds Of Réunion
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Extinct Birds Of Indian Ocean Islands
Extinction is the termination of an organism by the death of its last member. A taxon may become functionally extinct before the death of its last member if it loses the capacity to reproduce and recover. As a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, and mammoths. Through evolution, species arise through the process of speciation. Species become extinct when they are no longer able to survive in changing conditions or against superio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Feuilley
Jean Feuilley was a pilot engineer and cartographer who was sent to Réunion by the French East India Company to investigate the possibility of agricultural and marine exploitation. He arrived in the island in 1704 and the following year returned to France. His "Mission à l’île Bourbon du sieur Feuilley en 1704" (published 1705) contains among other things descriptions of now-extinct bird species, like the Réunion kestrel and the Réunion ibis The Réunion ibis or Réunion sacred ibis (''Threskiornis solitarius'') is an list of extinct birds, extinct species of ibis that was endemic to the volcanic island of Réunion in the Indian Ocean.

Rodrigues Pigeon
The Rodrigues pigeon or Rodrigues dove (''Nesoenas rodericanus'') is an extinct species of pigeon formerly endemic to the Mascarene island of Rodrigues (island), Rodrigues. It is known from a subfossil sternum and some other bones, and the descriptions of François Leguat, Leguat (1708) and Julien Tafforet (1726). Taxonomy This bird was assigned to the genus ''Alectroenas'', but this was erroneous. It is most similar to that of the ground doves (''Gallicolumba'') or to a miniature version of the sternum of an imperial pigeon (''Ducula''). If this similarity is not based on Convergent evolution, convergence, considering the evolutionary relationships of the dodo and the Rodrigues solitaire, the Rodrigues pigeon is quite possibly the closest relative of the Raphidae that was still alive in historic times. This does not mean that there is any close relationship between this bird and the didine pigeons, only that both derived, independently, from the same Indo-Asiatic lineage, which ...

Ulna
The ulna or ulnar bone (: ulnae or ulnas) is a long bone in the forearm stretching from the elbow to the wrist. It is on the same side of the forearm as the little finger, running parallel to the Radius (bone), radius, the forearm's other long bone. Longer and thinner than the radius, the ulna is considered to be the smaller long bone of the lower arm. The corresponding bone in the Human leg#Structure, lower leg is the fibula. Structure The ulna is a long bone found in the forearm that stretches from the elbow to the wrist, and when in standard anatomical position, is found on the Medial (anatomy), medial side of the forearm. It is broader close to the elbow, and narrows as it approaches the wrist. Close to the elbow, the ulna has a bony Process (anatomy), process, the olecranon process, a hook-like structure that fits into the olecranon fossa of the humerus. This prevents hyperextension and forms a hinge joint with the trochlea of the humerus. There is also a radial notch for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Pigeon
The blue pigeons are a genus, ''Alectroenas'', of birds in the dove and pigeon family Columbidae. They are native to islands in the western Indian Ocean. Taxonomy and evolution The genus ''Alectroenas'' was first described in 1840 by the English zoologist George Robert Gray with the Mauritius blue pigeon (''Alectroenas nitidissimus'') as the type species. The genus name combines the Ancient Greek ''alektruōn'', meaning "domestic cock", and ''oinas'', meaning "pigeon". The ''Alectroenas'' blue pigeons are closely interrelated and occur widely throughout islands in the western Indian Ocean. They are allopatric and can therefore be regarded as a superspecies. There are three extant species: the Madagascar blue pigeon, the Comoros blue pigeon, and the Seychelles blue pigeon. The three Mascarene islands were home to one species each, which are all extinct; the Mauritius blue pigeon, the Rodrigues blue pigeon, and the Réunion blue pigeon. The blue pigeons perhaps colonised the Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
