Dodo - Wikipedia. The dodo (Raphus cucullatus) is an extinctflightless bird that was endemic to the island of Mauritius, east of Madagascar in the Indian Ocean. The dodo's closest genetic relative was the also extinct Rodrigues solitaire, the two forming the subfamily. Raphinae of the family of pigeons and doves. The closest living relative of the dodo is the Nicobar pigeon. A white dodo was once thought to have existed on the nearby island of R. The dodo's appearance in life is evidenced only by drawings, paintings, and written accounts from the 1. Because these vary considerably, and because only some illustrations are known to have been drawn from live specimens, its exact appearance in life remains unresolved, and little is known about its behaviour. Though the dodo has historically been considered fat and clumsy, it is now thought to have been well- adapted for its ecosystem. It has been depicted with brownish- grey plumage, yellow feet, a tuft of tail feathers, a grey, naked head, and a black, yellow, and green beak. It used gizzard stones to help digest its food, which is thought to have included fruits, and its main habitat is believed to have been the woods in the drier coastal areas of Mauritius. One account states its clutch consisted of a single egg. It is presumed that the dodo became flightless because of the ready availability of abundant food sources and a relative absence of predators on Mauritius. The first recorded mention of the dodo was by Dutch sailors in 1. In the following years, the bird was hunted by sailors and invasive species, while its habitat was being destroyed. The last widely accepted sighting of a dodo was in 1. Its extinction was not immediately noticed, and some considered it to be a mythical creature. In the 1. 9th century, research was conducted on a small quantity of remains of four specimens that had been brought to Europe in the early 1. Among these is a dried head, the only soft tissue of the dodo that remains today. Since then, a large amount of subfossil material has been collected on Mauritius, mostly from the Mare aux Songes swamp. The extinction of the dodo within less than a century of its discovery called attention to the previously unrecognised problem of human involvement in the disappearance of entire species. The dodo achieved widespread recognition from its role in the story of Alice's Adventures in Wonderland, and it has since become a fixture in popular culture, often as a symbol of extinction and obsolescence. Taxonomy. The dodo was variously declared a small ostrich, a rail, an albatross, or a vulture, by early scientists. In 1. 84. 2, Danish zoologist Johannes Theodor Reinhardt proposed that dodos were ground pigeons, based on studies of a dodo skull he had discovered in the collection of the Natural History Museum of Denmark.

This view was met with ridicule, but was later supported by English naturalists Hugh Edwin Strickland and Alexander Gordon Melville in their 1. The Dodo and Its Kindred, which attempted to separate myth from reality. After dissecting the preserved head and foot of the specimen at the Oxford University Museum and comparing it with the few remains then available of the extinct Rodrigues solitaire (Pezophaps solitaria) they concluded that the two were closely related. Strickland stated that although not identical, these birds shared many distinguishing features of the leg bones, otherwise known only in pigeons.
They pointed to the very short keratinous portion of the beak, with its long, slender, naked basal part. Other pigeons also have bare skin around their eyes, almost reaching their beak, as in dodos. The forehead was high in relation to the beak, and the nostril was located low on the middle of the beak and surrounded by skin, a combination of features shared only with pigeons. The legs of the dodo were generally more similar to those of terrestrial pigeons than of other birds, both in their scales and in their skeletal features. Depictions of the large crop hinted at a relationship with pigeons, in which this feature is more developed than in other birds. Pigeons generally have very small clutches, and the dodo is said to have laid a single egg. Like pigeons, the dodo lacked the vomer and septum of the nostrils, and it shared details in the mandible, the zygomatic bone, the palate, and the hallux. The dodo differed from other pigeons mainly in the small size of the wings and the large size of the beak in proportion to the rest of the cranium. An atypical 1. 7th- century description of a dodo and bones found on Rodrigues, now known to have belonged to the Rodrigues solitaire, led Abraham Dee Bartlett to name a new species, Didus nazarenus, in 1. Based on solitaire remains, it is now a synonym of that species. Crude drawings of the red rail of Mauritius were also misinterpreted as dodo species; Didus broeckii and Didus herberti. For many years the dodo and the Rodrigues solitaire were placed in a family of their own, the Raphidae (formerly Dididae), because their exact relationships with other pigeons were unresolved. Each was also placed in its own monotypic family (Raphidae and Pezophapidae, respectively), as it was thought that they had evolved their similarities independently.

Evolution. 1. 84. Oxford specimen's foot, used as source for genetic studies. In 2. 00. 2, American geneticist Beth Shapiro and colleagues analysed the DNA of the dodo for the first time. Comparison of mitochondrialcytochrome b and 1. S r. RNAsequences isolated from a tarsal of the Oxford specimen and a femur of a Rodrigues solitaire confirmed their close relationship and their placement within the Columbidae. The genetic evidence was interpreted as showing the Southeast Asian Nicobar pigeon (Caloenas nicobarica) to be their closest living relative, followed by the crowned pigeons (Goura) of New Guinea, and the superficially dodo- like tooth- billed pigeon (Didunculus strigirostris) from Samoa (its scientific name refers to its dodo- like beak). This clade consists of generally ground- dwelling island endemic pigeons. The following cladogram shows the dodo's closest relationships within the Columbidae, based on Shapiro et al., 2. A similar cladogram was published in 2. Goura and Dicunculus and including the pheasant pigeon (Otidiphaps nobilis) and the thick- billed ground pigeon (Trugon terrestris) at the base of the clade. The DNA used in these studies was obtained from the Oxford specimen, and since this material is degraded, and no usable DNA has been extracted from subfossil remains, these findings still need to be independently verified. Based on behavioural and morphological evidence, Jolyon C. Parish proposed that the dodo and Rodrigues solitaire should be placed in the Gourinae subfamily along with the Groura pigeons and others, in agreement with the genetic evidence. The Mascarene Islands (Mauritius, R. Therefore, the ancestors of both birds probably remained capable of flight for a considerable time after the separation of their lineage. The Nicobar and spotted green pigeon were placed at the base of a lineage leading to the Raphinae, which indicates the flightless raphines had ancestors that were able to fly, were semi- terrestrial, and inhabited islands. This in turn supports the hypothesis that the ancestors of those birds reached the Mascarene islands by island hopping from South Asia. Despite its divergent skull morphology and adaptations for larger size, many features of its skeleton remained similar to those of smaller, flying pigeons. It was only slightly smaller than the dodo and the solitaire, and it too is thought to have been related to the crowned pigeons. Etymology. Landscape with Birds, showing a dodo in the lower right, Roelant Savery, 1. One of the original names for the dodo was the Dutch . The name was translated into German as Walchst. The original Dutch report titled Waarachtige Beschryving was lost, but the English translation survived: On their left hand was a little island which they named Heemskirk Island, and the bay it selve they called Warwick Bay.. But finding an abundance of pigeons & popinnayes . The meaning may not have been derived from penguin (the Portuguese referred to them as . The crew of the Dutch ship Gelderland referred to the bird as . This crew also called them . Some ascribe it to the Dutch word dodoor for . The first record of the word Dodaars is in Captain Willem Van West- Zanen's journal in 1. The English writer Sir Thomas Herbert was the first to use the word dodo in print in his 1. Portuguese, who had visited Mauritius in 1. Another Englishman, Emmanuel Altham, had used the word in a 1. Portuguese. As far as is known, the Portuguese never mentioned the bird. Nevertheless, some sources still state that the word dodo derives from the Portuguese word doudo (currently doido), meaning . It has also been suggested that dodo was an onomatopoeic approximation of the bird's call, a two- note pigeon- like sound resembling . In his 1. 8th- century classic work Systema Naturae, Carl Linnaeus used cucullatus as the specific name, but combined it with the genus name Struthio (ostrich). In 1. 76. 6, Linnaeus coined the new binomial Didus ineptus (meaning . This has become a synonym of the earlier name because of nomenclatural priority. Description. Dodo among Indian birds, by Ustad Mansur, c. As no complete dodo specimens exist, its external appearance, such as plumage and colouration, is hard to determine. Illustrations and written accounts of encounters with the dodo between its discovery and its extinction (1. According to most representations, the dodo had greyish or brownish plumage, with lighter primary feathers and a tuft of curly light feathers high on its rear end. The head was grey and naked, the beak green, black and yellow, and the legs were stout and yellowish, with black claws.
