Dodo bird (raphus cucullatus)

One more nice page about dodos: Description of the Dodo bird (raphus cucullatus) from the Birds of Mauritius site. The page starts with the dodo “portrait” above and the Old Print of a Dodo:

The dodo was a flightless bird native only to the island of Mauritius in the Indian Ocean. The dodo was a flightless member of the pigeon family. Fully grown dodos weighted about 23 kg (50 pounds). Around 1505 the Portuguese became the first Europeans to discover the dodo. By 1681 it had been driven to extinction by humans and the feral dogs, pigs, rats, and monkeys introduced by Europeans to Mauritius.

It talks a bit more about its history, the physical characteristics, natural history, including food habits, reproduction, habitat and behavior; and about the economic importance for humans, including the positive point and conservation, which means extinction. The “positive” description says:

The main purpose dodos served to humans, in the brief contact between the two species, was as food. The sailors frequently fed on wildlife from Mauritius while staying there, although it has been said that dodo meat was not particularly tasty. Still, they were hunted intensely, with sailors sometimes bringing back as many as 50 at a time. What they couldn’t eat right away they would salt and bring back with them. A few attempts were made to bring back a dodo alive. When this was successful, entrepreneurs would capitalize on the unique looks of the bird and tour the dodos around Europe, displaying them in cages and demonstrating how the dodo could “eat” stones. (Strickland and Melville, 1848) (Fuller, 1987)

I don’t want to copy all the text from the page, because it’s a good reference and I want people to visit it. The page also includes links to more dodo sites, scientific information, bibliography, and links to articles, included in the site. Almost all the articles were already blogged about here. I would like also to suggest their Images of the Dodo page.

Update: I removed all the links, since the whole site is gone and the links were broken.

Bones from the dodo’s foot

From LiveScience Bones Could Yield Dodo DNA: A newly discovered dodo skeleton has raised hopes for extracting some of the legendary extinct bird’s DNA.

Fred the dodo

Late last year, biologists looking for cave cockroaches accidentally discovered a dodo skeleton in the highlands of Mauritius.

Nicknamed “Fred” after one of its discoverers, the skeleton’s bones were badly decomposed and fragile, but there is still a good chance of extracting some dodo DNA because of the stable temperature and dry to slightly humid environment (keys to DNA preservation) of the cave.

(Scientists think Fred ended up in the bottom of the cave because he sought shelter from a violent cyclone but fell down in a deep hole and could not climb out.)

Dodo DNA would be of great scientific value because scientists know very little about the genetics of the dodo. Also, it would allow scientists to figure how long the skeleton was lying in the cave.

Mauritius turns wildlife clock back 400 years

A tiny Mauritius Fody

There are no dodos images, but it’s a very interesting news about Mauritius: Mauritius turns wildlife clock back 400 years from Reuters by Ed Harris:

Giant tortoises doze in the shade as rare lizards slip under bushes and endangered birds chatter in the sunlit trees overhead.

On a small wooded island off southern Mauritius, environmentalists are trying to turn back time to an era before humans ever set foot on the volcanic Indian Ocean archipelago.

“We want to turn the clock back 400 years,” says Ashok Khadun, a conservation expert with the Mauritian Wildlife Foundation (MWF), a local non-governmental organisation.

Sadly, they are too late to help the Mauritius giant skink — a type of large grey lizard — its broad-billed parrot, scops owl or lesser flying fox, and many other species now extinct.

And, of course, the dodos:

But the arrival of Europeans led by the Portuguese in the 16th century triggered an ecological disaster with the slashing of forest habitats and the introduction of predators like rats.

By far the most famous victim was the flightless dodo bird, which is believed to have died out in the late 1600s.

Dido

Do you remember the Dodo Expeditie Weblog? They are back with back. Or I rather say, they were back with the Dodo excavation 2007, because it ended in August 19th. The expedition was documented in a blog, as the previous one, with English and Dutch. The Dutch has a link the images of the new mascot Dido.

The expedition started with a fantastic new discover in its first day, July 29:

As soon as we set foot on Mauritius we headed for an excursion into the vast system of lavatunnels on the hilly side of the island. In the shadow of Julian Hume we entered a cave where speleologists discovered a complete dodoskeleton, only a month ago. This would be the first ever discovered in the Mauritian highlands. Soon it pointed out that also we would be lucky in the catacombs. In the smal chamber where the dodoskeleton was found Julain discovered the pelvis of the extinct Mauritian owl (Mascarenotus sauzieri)! Before this moment nobody knew this part of the postcranial skeleton of this species, it simply never was found. The Mauritian owl was the size of a forest owl, but had much bigger paws to kill reptiles. A most important find. How did the dodo and the owl ended in the cave, and how did they enter? Questions that immediately came to our minds and that we hopefully can answer with future research.

Dido find an owl bone

There are more information (and images) about this last expedition on their weblog posts. Check also the links on the main page of the expedition, including the Research plan. But before, a couple of Dido images:

Extinct Dodo Related to Pigeons

Wednesday, January 17th, 2007

An old news, from when they discovered that the Extinct Dodo Related to Pigeons, DNA Shows:

Dodo skeleton from Oxford University Museum of Natural History The dodo, poster bird for species extinction, has a pitiful reputation as a stupendously overweight idiot of a bird that couldn’t even fly. But scientific evidence is slowly correcting that impression. Its new rep: an evolutionary success, perfectly adapted to its living conditions, thin and relatively fast, but still an early victim to the spread of man. [...]

The adaptations the dodo made for island living—flightlessness and gigantism—have made understanding its evolutionary history and classifying it based on body characteristics difficult. Over the years, the dodo has been grouped with the carnivorous raptors; ratites, which include emus and ostriches; parrots; and shorebirds. Since the mid-1800s, the dodo has been classified as part of the family that includes pigeons and doves. But there has been no hard proof.

Molecular analysis of DNA retrieved from a dodo specimen at the Oxford University Museum of Natural History, England, confirms that the bird belongs firmly in the middle of the pigeon tree in evolutionary terms, reports a study published in the March 1 issue of the journal Science. Its closest living relative is the Nicobar pigeon, which lives in the Nicobar Islands and Southeast Asia, and it is part of a group of large island-dwelling birds that spend a great deal of time on the ground. Other modern representatives include the crowned pigeons of New Guinea and the tooth-billed pigeon of Samoa. [..]

“Island taxa such as the dodo and solitaire often represent extreme examples of evolution—and if we want to examine how we, or the life around us, evolved then such animals are very educational,” said Alan Cooper, a zoologist at the University of Oxford and one of the co-authors of the study. “By examining island birds we can investigate how evolution works—because extreme examples are often the best views of how something works.”

Earlier scientists had speculated that the dodo, and its closest relative, the also-extinct solitaire, descended from migratory African pigeons that got lost and colonized the islands. The genetic evidence clearly shows that the dodo and solitaire came from southeast Asia, where all their close relatives remain.

The Oxford scientists can’t tell when the dodo arrived on Mauritius, or when it became flightless. Geological evidence indicates that the island was created as a result of volcanic activity and emerged from the water about 8 million years ago. Whether the birds flew, swam or hitched a ride on floating debris like trees or clumps of seaweed, remains unknown. The DNA evidence does indicate that the dodo and the solitaire separated from a common ancestor about 25.6 million years ago. The common ancestor separated from other Southeast Asian birds around 42.6 million years ago.

It’s an excellent, but a bit long article to post. Check it all here.

Dodo in 1911

Friday, January 12th, 2007

What is a dodo according to Classic Encyclopedia, based on the 11th Edition of the Encyclopaedia Britannica (pub. 1911):

DODO (from the Portuguese Doudo, a simpleton), a large bird formerly inhabiting the island of Mauritius, but now extinct – the Didus ineptus of Linnaeus. When, in 1507, the Portuguese discovered the island which we now know as Mauritius they named it Ilha do from a notion that it must be the island of that name mentioned by Pliny; but most authors have insisted that it was known to the seamen of that nation as Ilha do Cisne- perhaps but a corruption of Cerne, and brought about by their finding it stocked with large fowls, which, though not aquatic, they likened to swans, the most familiar to them of bulky birds. In 1598 the Dutch, under Van Neck, took possession of the island and renamed it Mauritius. A narrative of this voyage was published in 1601, if not earlier, and has been often reprinted. Here we have birds spoken of as big as swans or bigger, with large heads, no wings, and a tail consisting of a few curly feathers. The Dutch called them Walgvogels (the word is variously spelled), i.e. nauseous birds, either because no cooking made them palatable, or because this island-paradise afforded an abundance of fare so much superior. De Bry gives two admirably quaint prints of the doings of the Hollanders, and in one of them the Walgvogel appears, being the earliest published representation of its unwieldy form, with a footnote stating that the voyagers brought an example alive to Holland. Among the company there was a draughtsman, and from a sketch of his, Clusius, a few years after, gave a figure of the bird, which he vaguely called “Gallinaceus Gallus peregrines,” but described rather fully. Meanwhile two other Dutch fleets had visited Mauritius. One of them had rather an accomplished artist on board, and his drawings fortunately still exist (see article Bird). Of the other a journal kept by one of the skippers was subsequently published.

This in the main corroborates what has been before said of the birds, but adds the curious fact that they were now called by some Dodaarsen and by others Dronten. 1 Henceforth Dutch narrators, though several times mentioning the bird, fail to supply any important fact in its history. Their navigators, however, were not idle, and found work for their naturalists and painters. Clusius says that in 1605 he saw at Pauw’s House in Leyden a dodo’s foot, 2 which he minutely describes. In a copy of Clusius’s work in the high school of Utrecht is pasted an original drawing by Van de Venne superscribed “Vera effigies huius avis Walghvogel (quae & a nautis Dodaers propter foedam posterioris partis crassitiem nuncupatur), qualis viva Amsterodamum perlata est ex insula Mauritii. Anno M.DC.XXVI.” Now a good many paintings of the dodo drawn from life by Roelandt Savery

(1576-1639) exist; and the paintings by him at Berlin and Vienna – dated 1626 and 1628 – as 1 The etymology of these names has been much discussed. That of the latter, which has generally been adopted by German and French authorities, seems to defy investigation, but the former has been shown by Prof. Schlegel (Versl. en Mededeel. K. Akad. Wetensch. ii. pp. 255 et seq.) to be the homely name of the dabchick or little grebe (Podiceps minor), of which the Dutchmen were reminded by the round stern and tail diminished to a tuft that characterized the dodo. The same learned authority suggests that dodo is a corruption of Dodaars, but, as will presently be seen, we herein think him mistaken.

And that is just the first part of the article. The image used to illustrated is the Solitaire of Rodriguez (Pezophaps solitarius), from Leguat’s figure, and that’s the reason:

The Solitaire of Rodriguez (Pezophaps solitarius)

The dodo is said to have inhabited forests and to have laid one large white egg on a mass of grass. Besides man, hogs and other imported animals seem to have exterminated it. But the dodo is not the only member of its family that has vanished. The little island which has successively borne the name of Mascaregnas, England’s Forest, Bourbon and Reunion, and lies to the southward of Mauritius, had also an allied bird, now dead and gone. Of this not a relic has been – handled by any naturalist. The latest description of it, by Du Bois in 1674, is very meagre, while Bontekoe (1646) gave a figure, apparently intended to represent it. It was originally called the “solitaire,” but this name was also applied to Pezophaps solitarius of Rodriguez by the Huguenot exile Leguat, who described and figured it about 1691.

The solitaire, Didus solitarius of Gmelin, referred by Strickland to a district genus Pezophaps, is supposed to have lingered in the 3 E. Newton and H. Gadow, Trans. Zool. Soc. xiii. (1893) island of Rodriguez until about 1761. Leguat l has given a delightful description of its quaint habits. The male stood about 2 ft. 9 in. high; its colour was brownish grey, that of its mate more inclined to brown, with a whitish breast. The wings were rudimentary, the tail very small, almost hidden, and the thigh feathers were thick and curled “like shells.” A round mass of bone, “as big as a musket ball,” was developed on the wings of the males, and they used it as a weapon of offence while they whirled themselves about twenty or thirty times in four or five minutes, making a noise with their pinions like a rattle. The mien was fierce and the walk stately, the birds living singly or in pairs. The nest was a heap of palm leaves a foot high, and contained a single large egg which was incubated by both parents. The food consisted of seeds and leaves, and the birds aided digestion by swallowing large stones; these were used by the FIG. 3. – Skeleton of a male Solitaire, Pezophaps solitarius, Museum of Zoology, Cambridge.
