A giant, flightless pigeon

Contrary to what its appearance might suggest, the dodo was not related to the ostrich, the turkey, or any other flightless bird. It belonged to the family of Columbidae, that of pigeons and doves. This relationship, long suspected by 19th-century anatomists based on certain details of the skull and beak, was definitively established by molecular genetics in the early 2000s: in 2002, Beth Shapiro's team published a mitochondrial DNA analysis confirming that the closest living relative of the dodo is the Nicobar pigeon (Caloenas nicobarica), a bird with iridescent green and blue plumage, about the size of a small common pigeon, still found in the islands of Southeast Asia and eastern Indonesia. This relationship was reconfirmed in 2022, when an international team announced they had sequenced the dodo's complete genome from ancient DNA.

Its flying ancestors reached Mauritius millions of years ago, likely carried by air currents from Southeast Asia, long before humans set foot on the island. In an island environment devoid of terrestrial predators and rich in ground-based food, flight gradually lost its purpose—it is energy-intensive and useless when there is no one to flee from. Over generations, the bird underwent what biologists call island syndrome: increased body size, loss of flight ability, atrophy of the pectoral muscles, strengthening of the legs to bear increased weight, and loss of the instinctive fear of predators. The same process has affected many island birds around the world—from penguins on subantarctic islands to rails in the Pacific—but few have gone as far as the dodo.

Morphology

The dodo stood about one meter tall. Modern estimates of its weight, based on reconstructions from complete bones and biomechanical models published notably by Delphine Angst and Eric Buffetaut in the 2010s, place it between 10 and 17 kilograms—significantly less than the 20-25 kilograms long attributed to it based on historical depictions. These inflated estimates likely reflected the condition of overfed captive specimens observed in 17th-century Europe, or a seasonal bias: the dodo appears to have accumulated substantial reserves during the fruit season before molting, which would explain the considerable variation in its weight throughout the year.

Its head, disproportionately large compared to its body, bore a massive, hooked beak, black at the tip and yellowish at the base, perfectly adapted for crushing fruits, seeds, and tough plant matter. The plumage was grey-brown on the back and flanks, lighter on the breast, tending towards white or pale grey. The short tail consisted of a few ruffled feathers, likened to a feather duster in contemporary accounts. The robust, yellow legs, with four clawed toes, effectively supported the animal's weight on the rugged forest floor. The vestigial wings were no longer used for flight but likely served for balance during rapid movements, visual communication (displays, aggression signals), and possibly thermoregulation.

Examination of the long bones also reveals an interesting feature: their internal structure suggests a marked seasonal growth cycle, with the bird likely reaching its adult size over several years, unlike modern pigeons which grow rapidly. Modest sexual dimorphism is suspected based on the variability of the bones from Mare aux Songes, but remains difficult to establish with certainty.

Etymology of a name that has become universal

The origin of the word "dodo" has long been debated. Two hypotheses prevail. According to the first, the name comes from Portuguese. doudo ("simple-minded"), given by Portuguese sailors because of the bird's lack of wariness. According to the second, more popular today, the word derives from Dutch dodoor ("lazy") or of dodaars (referring to its bushy tail). Early Dutch sailors also called it that. walghvogel ("disgusting bird"), a reference to its flesh which testimonies describe as tough and unappetizing.

Whatever its exact origin, the word became established in all European languages during the 17th century, and then throughout the world. The English expression dead as a dodo ("dead like a dodo") testifies to the depth with which the bird's name has become entrenched in common parlance as an absolute synonym for extinction.

Behavior and diet

The dodo was primarily frugivorous. It fed on fallen fruit, seeds, roots, and probably, occasionally, small invertebrates. By digesting the fruit it consumed, it actively participated in the dispersal of seeds for many plant species endemic to the island—a major ecological role whose exact extent is still debated among scientists. The massive beak and powerful jaw muscles reconstructed from skulls suggest that it was capable of tackling tough fruit and even large seeds, which would have made it a particularly valuable dispersal agent for certain large-seeded species.

Knowledge about its reproduction remains limited. Contemporary accounts and recent bone analyses suggest that the bird laid a single egg in a simple nest on the ground, and that the young grew rapidly during the fruit season before reaching adult size over several years. This reproductive strategy—few eggs, prolonged dependence of the juveniles, and ground nesting—was perfectly viable in an environment without terrestrial predators. It proved catastrophic in the face of introduced species: a single pig or rat could destroy the entire reproductive effort of a pair for a whole year.

Contrary to its persistent reputation as a stupid and clumsy creature, the dodo was neither. Historical accounts describe a curious bird capable of learning. Its supposed stupidity stemmed from one specific trait: a complete lack of distrust towards humans, a logical consequence of millions of years spent without land predators. Sailors needed no strategy to approach it—they simply had to bend down and grab it. This docility, fatal to the species, profoundly influenced early European chroniclers and contributed to solidifying the image of an absurd animal, when in reality it merely reflected the absence of an instinct the bird had never needed.

The dodo and its cousins from the Indian Ocean

The Mauritius dodo was part of a small group of related birds, unique to the western Indian Ocean. The neighbouring island of Rodrigues was home to the Rodrigues solitaire (Pezophaps solitaria), a long-necked, flightless bird, more slender than the dodo, which survived somewhat longer—the last reliable sightings date from the second half of the 18th century, and its extinction is generally placed around 1760–1780, nearly a century after that of the dodo. Like the dodo, the Rodrigues solitaire has been the subject of valuable historical descriptions, notably that of the Huguenot François Leguat, who stayed on Rodrigues between 1691 and 1693 and left a particularly detailed account.

The existence of a third bird, the "Réunion solitaire," long considered a close relative of the dodo, is now disputed. Recent paleontological and iconographic research, notably conducted by Cécile Mourer-Chauviré, suggests that historical accounts of this bird may actually refer to a white ibis, the Threskiornis solitarius, without close kinship with the dodo. Dodo and Rodrigues solitaire thus form, based on the current state of knowledge, a unique evolutionary radiation of giant flightless pigeons, specific to this region of the world — a group that scientists group in the subfamily Raphinae.

An isolated volcanic island

Mauritius is a volcanic island in the western Indian Ocean, located approximately 900 kilometers east of Madagascar. With a modest surface area (around 2,040 km²), it was formed by volcanic activity in the Mascarene hotspot approximately eight million years ago. This relatively recent geological history, combined with its complete isolation—no nearby continent or archipelago has allowed for the regular arrival of species—explains the extraordinary endemic biodiversity that the island harbored before human arrival.

The tropical climate, characterized by a distinct seasonality between rainy and dry seasons, and the varied topography (coastal plains, central plateaus, and mountain ranges reaching over 800 meters) have allowed the development of several types of forests: humid mountain forests, lowland dry forests, coastal marshes, and mangroves. This mosaic of habitats has fostered a considerable diversification of local species.

A primary forest with exceptional endemism

Before the arrival of humans, Mauritius was almost entirely covered in dense rainforest. The island's isolation allowed for the development of a remarkable rate of endemism, comparable to that of the Galápagos or Hawaii: the vast majority of Mauritian plant and animal species existed nowhere else on the planet. The flora included more than 700 species of vascular plants, a considerable proportion of which were strictly endemic.

Among the emblematic trees of this primeval forest, we can mention the ebony of Mauritius (Diospyros tessellaria), with extremely dense black wood, prized in Europe from the 17th century onwards; mat wood (Labourdonnaisia calophylloides) ; olive wood (Orientalis Cassine); several species of endemic palm trees, now extremely rare, such as the blue palm (Hyophorbe vaughanii); the tambalacoque (Sideroxylon grandiflorum), sometimes nicknamed the "dodo tree" because of a now-famous hypothesis (see below); or the brown coffee (Ramosmania rodriguesii), long believed to be extinct and rediscovered as a single wild individual in Rodrigues in the 1980s.

The ecological role of the dodo

In 1977, the American scientist Stanley Temple, in an article published in the journal ScienceIt was suggested that the tambalacoque tree, whose seedlings were extremely rare in Mauritius, depended on its seeds passing through the dodo's digestive system to germinate. The extinction of the dodo would thus have triggered a reproductive crisis in the tree, whose last remaining individuals were dying of old age without having been able to reproduce. This appealing and widely circulated hypothesis has since been nuanced—or even challenged—by subsequent research.

Other species, including giant tortoises that are also extinct, likely played the same role as large-seed dispersers, and some tambalacoque trees still reproduce today without the help of a giant disperser—suggesting that the dependence was not absolute. Contemporary ecologists now consider the "Temple hypothesis" to be partially valid: the dodo was probably an important disperser for tambalacoque and other large-seeded species, but not the sole agent of their reproduction. What science now acknowledges is that the dodo was part of a complex network of ecological relationships with the native flora, and that its extinction—within a broader collapse that included giant tortoises—contributed to the lasting disruption of this balance.

Wildlife that disappeared in the process

The dodo is not the only one to have disappeared. Mauritius has lost, in the same decades, a considerable part of its endemic fauna. Two species of giant land tortoises, unique to Mauritius (Cylindraspis triserrata And Cylindraspis inepta), were eradicated at the end of the 17th or the beginning of the 18th century, mainly through hunting—their flesh being much more prized than that of the dodo, and their ability to survive for months in the hold made them ideal fresh meat for long voyages. Several large endemic reptiles, several endemic flightless or flying birds—such as the red rail (Aphanapteryx bonasia), the broad-beaked parrot (Lophopsittacus mauritianus), the kingfisher of Mauritius — as well as endemic bats (the lesser oil bat, Pteropus subniger(extinct in the 19th century) and a significant part of the invertebrate fauna also disappeared.

The dodo has become the symbol of this collective extinction, but the collapse it embodies was in reality a widespread ecosystem collapse — one of the best documented, and one of the fastest, in natural history.

The first contacts

Arab navigators likely sighted Mauritius as early as the 10th century, and medieval Arab-Persian maps mention the Mascarene Islands under various names. The Portuguese reached the island in the early 16th century—Diogo Fernandes Pereira is believed to have been the first European to land there around 1507—but they did not establish a permanent settlement, preferring better-situated trade routes. The island, which they called "Cirne," was never the site of a permanent Portuguese settlement.

The first documented contact with the dodo dates back to the late 16th century, when the Dutch arrived. The first European accounts describe with astonishment this large bird that does not flee from humans and that one can approach without caution.

Dutch colonization (1598-1710)

In September 1598, the Dutch expedition commanded by Wybrand van Warwijck, part of Jacob Corneliszoon van Neck's fleet, landed at Mauritius and renamed the island Mauritius, in honor of Prince Maurice of Nassau, Stadtholder of the Netherlands. The permanent settlement followed, with an initial coastal location in the southeast of the island, around the bay of Vieux Grand Port, where the [city name] would be built a few decades later. Fort Frederik HendrikIt is from this period onwards that ecological transformations accelerate.

The Dutch presence unfolded in two phases. The first phase of occupation (1598-1658) saw the establishment of small stations primarily intended for the port of call of Dutch East India Company ships en route to Batavia, the exploitation of ebony, and the introduction of crops and livestock. This first phase was a partial failure: cyclones, rat infestations that ravaged crops, and health problems led the Company to abandon the island in 1658. A second phase of occupation (1664-1710) saw a more structured attempt at colonization, but this too ended in failure and final abandonment in 1710. When the French took possession of the island in 1715 and renamed it "Île de France," the dodo had already been extinct for several decades.

The dodo was hunted for its meat, but it wasn't the primary cause of its extinction. Contemporary accounts describe its tough, unappetizing flesh—which is what earned the bird its Dutch nickname, "the dodo." walghvogelThe "disgusting bird" was a common term among sailors, who preferred other birds, especially giant tortoises, which were far tastier and could be taken on board alive to serve as fresh meat for weeks. The direct impact of hunting alone would probably not have been enough to wipe out the species.

Logging was a far more destructive factor. Mauritian ebony was an extremely sought-after resource in Europe, and its intensive exploitation fragmented and then destroyed the dodo's natural habitat in just a few decades. By the end of the 17th century, the areas of primary forest accessible to the Dutch were already largely depleted.

Invasive species: the final blow

The decisive factor in the extinction of the dodo was the introduction, deliberate or accidental, of animals that the Mauritian ecosystem had never known and to which the dodo was in no way adapted.

• Domestic pigsReleased by sailors as a source of live meat from the late 16th century onwards, they quickly became wild and devoured eggs and chicks.
• Black rats (Rattus rattus) and the miceHaving disembarked from the ships, they plundered the nests on the ground and permanently compromised the reproduction of all nesting fauna. The rat probably arrived as early as the first Portuguese shipwrecks.
• Cats and dogs, escaped or abandoned, have directly preyed on young and adults.
• Goats and cattleIntroduced for farming, they have massively degraded the vegetation and therefore the dodo's food source.
• Crab-eating macaques (Macaca fascicularis)Introduced later (probably in the 17th century by Portuguese or Dutch ships from Southeast Asia), they also impacted the reproduction of ground-nesting birds — and continue to be a scourge for Mauritius' surviving endemic fauna.

The combined effect was devastating. The dodo, which laid a single egg on the ground and had developed no defensive behaviors, simply could not reproduce quickly enough to compensate for these losses. Each breeding season ended in near-total failure in areas where the invasive species were present.

Timeline of decline and date of extinction

Between 1598 and 1650, the dodo population collapsed rapidly, primarily due to habitat destruction and predation by introduced species. Between 1650 and 1680, the remaining populations fragmented into small, isolated groups in the least accessible forested areas. The last eyewitness account considered reliable by most specialists is that of the Dutch sailor Volkert Evertsz, shipwrecked on an islet near Mauritius in 1662, who described the capture of birds identified as dodos—although some researchers have recently suggested they might have been another species, the red rail.

Statistical analysis of observation dates, notably carried out by David Roberts and Andrew Solow in 2003 using a mathematical model applied to historical accounts, suggests a probable extinction date around 1690, with a confidence interval extending from the 1680s to the 1710s. Some later accounts exist in Dutch archives, but their reliability is now disputed.

In less than a century, a species that had evolved for millions of years in the isolation of its island had disappeared. The pace of this extinction—just a few human generations—remains one of the fastest documented cases for a large vertebrate.

The first European stories

Descriptions of the dodo by navigators vary considerably in accuracy. The journal of the 1598 Dutch expedition, published by Jacob Corneliszoon van Neck upon his return, contains one of the earliest European descriptions, mentioning a bird "as big as a swan," with a beak similar to that of an eagle. A few years later, the Flemish botanist Carolus Clusius (Charles de l'Écluse) repeated these descriptions in his Exoticorum libri decem (1605), accompanied by engravings which would for a long time be the main iconographic sources available in Europe.

Other Dutch, English, and French accounts followed during the 17th century. The English traveler Sir Thomas Herbert described in 1634, in his Travels, a bird “bigger than a turkey, deformed and stupid” — illustrating how deeply the impression of absurdity had already permeated the European imagination. The French navigator François Cauche, who passed by Mauritius in 1638, offers a more detailed and neutral description, notably mentioning the bird's characteristic cry and certain aspects of its social behavior.

Particularly valuable is the account of the English aristocrat Sir Hamon L'Estrange, who described seeing a live dodo in London in 1638, exhibited in a street for an entrance fee. This is one of the few direct accounts of a live dodo being observed in Europe, and it confirms that several specimens were indeed brought from Mauritius—although most probably did not survive long in captivity.

These accounts, valuable but sometimes contradictory, are now systematically re-examined in light of modern paleontological data. Certain details once taken at face value—the bird's extreme heaviness, its near immobility—are now considered exaggerated, and often reflect the condition of overfed captive specimens in Europe rather than that of wild animals on their island.

Artistic representations

Paintings and engravings of the period, primarily produced in Europe from live or stuffed specimens brought back by sailors, profoundly shaped the popular image of the dodo. The works of the Flemish painter Roelandt Savery (1576–1639), executed in the 1620s and 1630s, are among the most famous—and among those that most contributed to solidifying the image of a clumsy, pot-bellied, almost caricatured bird. Savery, who probably never saw a live dodo himself, painted the bird repeatedly in allegorical compositions populated with exotic animals. His famous Edward's Dodo (1626), now kept at the Natural History Museum in London, remained for centuries the absolute visual reference.

Other historical representations deserve mention. A miniature attributed to the Indian artist Ustad Mansur, painter at the court of the Mughal emperor Jahangir, kept in the Hermitage Museum in Saint Petersburg, is thought to date from the 1620s. It shows a dodo that was supposedly brought alive to India - proof that the bird circulated well beyond Europe - and is considered one of the most faithful representations we have, the artist probably having worked from the live model.

Modern scientific reconstructions, based on bone analysis, depict a dodo as significantly more slender and athletic than the one in Savery's paintings. The captive specimens painted in Europe had likely been overfed and observed in a physiological state far removed from that of wild dodos. British paleoartist Julian Hume, one of the leading contemporary experts on the dodo, produced several reconstructions in the 2000s and 2010s incorporating recent osteological data, which present a much more dynamic bird than the traditional image.

The Oxford Dodo

The only known complete stuffed dodo specimen in modern times, housed in the Ashmolean Museum, Oxford, originally came from the private collection of John Tradescant the Younger, a 17th-century English naturalist who donated it to the university. The specimen—believed to be the live dodo seen by Sir Hamon L'Estrange in London in 1638—was destroyed by moths in the mid-18th century. Only the head (with some of the skin) and one leg survived the destruction and are now in the Museum of Natural History, Oxford University.

These two fragments remain among the few remaining soft tissue remains of the dodo available to researchers. They have played a considerable role in modern genetic studies: it was notably from DNA extracted from the Oxford Dodo that Beth Shapiro was able, in 2002, to definitively establish the relationship between the dodo and the Nicobar pigeon. A few other soft tissue remains exist around the world—notably at the National Museum of Natural History in Paris, in Copenhagen, and in Prague—but their state of preservation varies greatly.

Strickland's foundational work

The systematic scientific study of the dodo truly began in 1848 with the publication by British zoologists Hugh Strickland and Alexander Melville of a major work, The Dodo and Its KindredFor the first time, historical accounts, iconography, and the few anatomical remains known at the time were gathered, compared, and methodically analyzed. It was Strickland who established the dodo's relationship to pigeons, a bold hypothesis at the time, and laid the foundation for all subsequent research. His book remains the definitive source on the dodo, nearly two centuries after its publication.

Mare aux Songes, the invaluable deposit

In 1865, on the southeast coast of Mauritius, schoolteacher George Clark identified an exceptional deposit of fossilized bones in a marsh near Plaine Magnien: those of the dodo, but also of several other species extinct on the island. This site, known as Mare aux Songes (Dream Pond), is actually a volcanic depression filled with ancient lacustrine sediments, where the bones of animals that came to drink or died trapped there accumulated over the last few millennia.

Clark's discovery sparked a wave of scientific enthusiasm. Some of the bones were sent to Richard Owen, the renowned 19th-century British anatomist, who published the first detailed study of the skeleton in 1866. Other bones were studied by the Mauritian physician and naturalist Antoine Caillou and by European researchers. For the first time, anatomical material was available that allowed scientists to move beyond historical iconography and the sometimes fanciful descriptions of navigators.

New excavations were carried out in the 21st century, particularly between 2005 and 2007 under the direction of the Dutch team led by Kenneth Rijsdijk (University of Amsterdam), in collaboration with Mauritian researchers. These campaigns yielded more bones than the entire 19th century combined, and provided a better understanding of the precise ecological context in which the dodo lived: the sediments contain remains of plants, pollen, insects, and other animals that allow researchers to reconstruct the bird's environment just before human arrival. Mare aux Songes is now recognized as one of the world's most important paleontological sites for the study of recent island extinctions.

The contribution of paleogenomics

Analysis of ancient DNA extracted from the dodo's remains confirmed what its morphology suggested: the bird was indeed a pigeon, closely related to the Nicobar pigeon. The first genetic demonstration dates back to 2002, when Beth Shapiro, then at Oxford University, published a study of mitochondrial DNA extracted from the Oxford Dodo.

In 2022, an international team announced that it had successfully sequenced the complete genome of the dodo, again under the direction of Beth Shapiro (who has since become Chief Science Officer at Colossal Biosciences), using DNA extracted from a specimen housed at the Natural History Museum of Denmark. This breakthrough is considered a decisive step for future research, including controversial de-extinction projects. The sequenced genome is not perfect—ancient DNA is always degraded, fragmented into short segments, and its computer assembly inevitably has gaps—but it provides an unprecedented working basis for biologists.

Biomechanics and behavioral ecology

Recent biomechanical studies, based on the digital reconstruction of complete skeletons, have radically altered our understanding of the dodo. Far from being the clumsy, slow animal depicted in Savery's engravings, the dodo now appears as an agile runner, capable of rapid movement across forest floors and likely well-adapted to its environment. Analysis of bone growth, notably published by Delphine Angst and her team in 2017, also suggests a life cycle aligned with the tropical seasons of Mauritius: reproduction and rapid growth during the fruiting season (August-March), followed by molting (March-July), with significant weight fluctuations throughout the year.

This renewed image of a dynamic, ecologically specialized, and finely adapted dodo makes its extinction all the more striking: it wasn't an animal "outpaced by evolution" that disappeared, but a species perfectly adapted to its island—until the moment its island ceased to be the same. The dodo's extinction was not the result of internal degeneration; it was the sudden and unforeseen effect of an external change whose magnitude exceeded the species' capacity to adapt.

On coats of arms and currency

The dodo features on the coat of arms of Mauritius, where it is depicted as a heraldic supporter holding sugarcane, alongside a sambar deer (a deer introduced to Mauritius in the 17th century and now emblematic of the local fauna). These arms, designed by British heraldists in the early 20th century, were officially adopted in 1906 under the British Mandate and then confirmed without modification upon independence in 1968. They bear the motto Stella Clavisque Maris Indici — “the star and key of the Indian Ocean.” The bird also appears on several denominations of the Mauritian rupee—banknotes and coins—and on numerous official documents, from passports to uniforms. No other extinct animal likely holds such a central place in a country's identity.

On the national flag However, the dodo does not appear: the Mauritian flag is purely geometric, composed of four horizontal stripes (red, blue, yellow, green). But the coat of arms and the flag coexist as official symbols, and the dodo remains, as such, one of the most recognizable emblems of the country.

The dodo in world literature

The bird gained its international fame thanks to Lewis Carroll, who made it a character in Alice in Wonderland (1865). Carroll's dodo has an amusing biographical dimension: Charles Lutwidge Dodgson, Carroll's real name, had a slight stutter and used to introduce himself by saying "Do-do-Dodgson"—hence, according to several biographers, the choice of the dodo as the author's avatar in the story. The book's worldwide success cemented the dodo in the Western imagination as the archetype of the extinct animal, sometimes even becoming a stock phrase: dead as a dodo"Dead as a dodo" is now a common expression in English to refer to something that has definitively ceased to exist.

The bird has since inspired countless literary works, comic books, animated films, and video games. In cinema, it appears in family productions such as Ice Age, where it is the subject of a recurring joke; in scientific literature, it is invoked in almost every general work on extinctions caused by humanity, from David Quammen's seminal book The Song of the Dodo (1996) to recent work on the Anthropocene.

A tourist and commercial icon

In Mauritius, the dodo is everywhere: on bottles of Phoenix beer, brewed since 1963 and recognizable by its logo depicting the bird; in souvenir shops as plush toys, figurines, t-shirts, and piggy banks; on company logos; on restaurant signs; and on the packaging of local products. This commercial omnipresence is sometimes criticized as trivializing, or even as a paradoxical form of commodification of, a species that the ancestors of Mauritians (and more precisely, the Dutch colonizers and their successors) helped to eradicate. But it also testifies to a deep and unusual attachment of a population to an animal that none of its members has ever seen, making the dodo a textbook case in the study of the relationship between national identity and natural heritage.

No living dodo exists anymore, of course. But Mauritius offers several places where visitors can learn about its history, see its remains, observe its reconstructed ecosystem, or contemplate life-size replicas. Here are the main ones.

The Natural History Museum of Port-Louis

This is an absolute must-see for anyone interested in the dodo. Located in the historic Mauritius Institute building, near the Company Garden in the heart of Port Louis, the Port-Louis Natural History Museum The museum houses a reconstructed dodo skeleton made from authentic bones found at Mare aux Songes, as well as a series of plates, paintings, and reproductions retracing the history of the bird and its scientific rediscovery. Founded at the end of the 19th century, the museum is one of the oldest in the Indian Ocean. Admission is free, and the museum often serves as a first stop on a cultural visit to the capital.

Egret Island

Off the southeast coast, opposite Pointe d'Esny, theÎle aux Aigrettes The island is a nature reserve managed by the Mauritian Wildlife Foundation. Once degraded by logging and overrun with introduced species, the islet has been the subject of an exemplary ecological restoration program since the 1980s: the elimination of invasive species, the replanting of endemic trees, and the reintroduction of endangered species such as the Aldabra giant tortoise (as an ecological replacement for the extinct Mauritian tortoises). The guided tour, lasting approximately two hours, offers a glimpse into what the forest inhabited by the dodo once looked like. A life-size statue of the bird has been erected to commemorate its past presence, and local guides recount the story of its extinction and the more optimistic narrative of the ongoing ecological restoration.

La Vanille Nature Park

In the south of the island, at Rivière des Anguilles, La Vanille Nature Park It houses one of the world's largest captive populations of giant tortoises, as well as various species of Mauritian and international wildlife (crocodiles, lemurs, reptiles). Founded in 1985, the park also features a section dedicated to the dodo, with life-size reconstructions, educational panels, and an exhibition on the island's historical extinctions. It is an excellent complement to the Port Louis Museum, and is particularly well-suited for families and visits with children.

The Mahebourg History Museum

Housed in a former 18th-century colonial building at the entrance to the town of Mahebourg, the Mahebourg National History Museum The museum dedicates part of its collection to the Dutch period and the first contacts between Europeans and Mauritian wildlife. It includes some dodo bone remains and period illustrations, all within the broader context of the island's colonial history. Admission is free.

Fort Frederik Hendrik and the Pond of Dreams

Still in the southeast, a few kilometers north of Mahebourg, the Fort Frederik Hendrik Vieux Grand Port marks the location of the first permanent Dutch settlement, where the transformations that would ultimately lead to the dodo's extinction began. The small museum on site recounts this period and displays archaeological artifacts found there. A few kilometers away lies Mare aux Songes, the paleontological site from which most of the known dodo bones originate. The site itself is not open to the public, and there is nothing to see on the surface, but its proximity to the fort lends a certain geographical coherence to the visit—one understands that it was in this precise corner of the island, around the bay of Vieux Grand Port, that the dodo's fate was essentially sealed.

National parks for understanding the ecosystem

To understand what the dodo's habitat looked like, a visit to Black River Gorges National ParkThe area, where some of Mauritius' last remaining native forests still exist, is particularly enlightening. Several trails allow visitors to cross areas of restored vegetation and observe the surviving endemic flora. endemic garden of the Osterlog valley, in the centre of the island, also offers an educational presentation of the original Mauritian flora, with easy access and good signage.

A question that has become concrete

Long confined to science fiction, the idea of bringing an extinct species back to life began to acquire the status of a serious scientific project with the progress of genetic engineering, in particular the CRISPR-Cas9 genome editing developed in the 2010s. The sequencing of the dodo's complete genome, published in 2022, marked an important step: for the first time, a complete genetic blueprint of the bird was available, admittedly imperfect but usable.

The American company Colossal Biosciences, founded in 2021 by entrepreneur Ben Lamm and Harvard University geneticist George Church, and already known for its projects to "de-extinct" the woolly mammoth and the Tasmanian tiger, announced in January 2023 its intention to work on de-extinction for the dodo. Geneticist Beth Shapiro, a leading global expert in the paleogenomics of extinct birds, joined the company in 2024 as chief scientist. The proposed approach involves genetically editing primordial germ cells (PGCs) from the Nicobar pigeon (the technique being specific to the reproductive biology of birds), gradually aligning them with the dodo genome, and then implanting them into host bird embryos that would raise the chicks.

Significant obstacles

Even assuming technical feasibility, several major difficulties remain. Ancient DNA is always degraded, and the sequenced dodo genome remains an imperfect computer assembly — it probably lacks hundreds of genes, and the precise mapping of regulatory regions is difficult to reconstruct.

The reproductive biology of birds also considerably complicates the work. Unlike mammals, where nuclear transfer cloning is now a relatively well-established technique, bird eggs are not suitable for these techniques. It is necessary to work with primordial germ cells, which involves a cascade of manipulations: extracting PGCs from the Nicobar pigeon, editing them to make them closer to the dodo genome, reinjecting them into host embryos, selecting individuals whose germline is correctly modified, and breeding these individuals together to obtain a first "dodo" generation. The preliminary work to develop these techniques is currently being carried out in the rock pigeon (Columba Livia), much easier to study in the laboratory.

Finally, and this is probably the most profound difficulty: a bird that hatched from an egg, even one genetically "dodo," would not be a dodo in the ecological sense of the term. It would lack learned behaviors, cultural transmission within a wild population, and above all, the ecosystem in which it evolved—an ecosystem that has largely disappeared, where the trees dispersed by the dodo, the plants it fed on, and the insects with which it interacted are now only present in a fragmentary way.

The ethical debate

The project raises questions that go far beyond technical considerations. Should considerable financial resources be devoted to resurrecting a species that disappeared three centuries ago rather than protecting those that are currently threatened? What would be the well-being of an animal reintroduced into a profoundly altered ecosystem, where its ecological partners have themselves disappeared and where the invasive species that caused its extinction still thrive? Doesn't the promise of "de-extinction" risk weakening the sense of urgency surrounding conservation by suggesting that extinction is now reversible, and therefore that it is less serious to let current species disappear?

These debates are far from settled, and within the scientific community itself, traditional conservationists—who believe the money and media attention devoted to de-extinction would be much better spent protecting living species—are pitted against more enthusiastic biologists who see new biotechnologies as an additional tool for repairing some of the ecological damage caused by modernity. Several officials from the Mauritian Wildlife Foundation have spoken cautiously about the Colossal project, reiterating that the absolute priority in Mauritius remains the protection of the remaining endemic species, many of which are on the verge of extinction.

The surviving endemic species

Despite the mass extinctions of recent centuries, Mauritius still harbors remarkable endemic biodiversity, and since the 1970s, the island has become a testing ground for some of the world's most advanced conservation techniques. Several bird species unique to the island are now actively protected.

Mauritius's kestrel (Falco punctatusThe small, endemic falcon, the hawk-hawk, is probably the most emblematic case. By the mid-1970s, the global population had dwindled to just four known individuals, making it one of the most endangered species on the planet. Thanks to the tireless work of Welsh biologist Carl Jones and his teams, who developed a spectacularly successful captive breeding and reintroduction program, the population now numbers in the wild at several hundred. It is one of the greatest success stories of modern conservation.

Maurice's echo or Maurice's parakeet (Psittacula eques), an endemic parrot, was also saved at the last minute in the 1980s-1990s, using similar methods. The pink pigeon (Nesoenas mayeri), the island's only surviving endemic pigeon — another distant cousin of the dodo — was also on the brink of extinction in the 1980s, with fewer than twenty known individuals, and has been restored to more than five hundred individuals today.

On the reptile side, the boa constrictorRound Island (Casarea dussumieri), an endemic snake surviving only on this islet in northern Mauritius, and several endemic geckos such as the Telfair skink (Leiolopisma telfairii) are the subject of active conservation programs. The Mauritian flora, although profoundly altered, retains more than six hundred endemic plant species, some of which are among the rarest in the world, and is the subject of propagation and reintroduction campaigns.

The Mauritian Wildlife Foundation

Conservation in Mauritius relies heavily on the work of the Mauritian Wildlife Foundation (MWF), a local organization founded in 1984 that has since led some of the world's most effective species conservation programs. The MWF manages the Île aux Aigrettes reserve, oversees captive breeding programs, coordinates invasive species eradication efforts on offshore islets, and carries out much of the public awareness and education work in Mauritius. The MWF partners with several international organizations, notably the Durrell Wildlife Conservation Trust, founded by the writer and naturalist Gerald Durrell, who took an early interest in Mauritian wildlife.

Habitat restoration

Several protected areas are the focus of in-situ conservation efforts. Black River Gorges National Park, established in 1994, covers approximately 6,500 hectares in the southwest of the island and is home to the last significant native forests. Bras d'Eau National Park, in the northeast, protects another collection of forests and wetlands. Several offshore islets—Round Island, Egret Island, Snake Island, and East Island—are the subject of intensive restoration programs, with the methodical eradication of invasive species (rats, rabbits, goats) often being the first step in any ecological restoration on these islands.

This work is long-term, costly, and sometimes locally controversial—the eradication of species, even invasive ones, raises significant ethical and logistical questions. But it is beginning to bear fruit: populations of endemic species on these restored islets are recovering, and natural regeneration of native vegetation is observed when the pressure from invasive species is sufficiently reduced.

What the dodo taught us

The extinction of the dodo has become, worldwide, the archetype of a human-caused extinction. It illustrates several principles now central to conservation biology. First, the particular vulnerability of island species, which have evolved without certain predators and are therefore not adapted to them—an observation that now applies to all the world's oceanic islands, where the rate of extinctions remains abnormally high.

Next, the synergistic nature of the extinction factors: habitat destruction alone, or predation alone, might not have been enough to wipe out the dodo—it was their combination that proved fatal. This lesson remains central to contemporary conservation: isolating a single threat is rarely sufficient; action must be taken simultaneously on several fronts.

Finally, the decisive importance of prevention over emergency measures, and the devastating role of invasive species, which remains today one of the main causes of extinction in the world's island ecosystems — even ahead of direct habitat destruction in some regions.

In Mauritius, these lessons are translated into concrete actions. Every visit to Île aux Aigrettes, every donation to the MWF, every entrance ticket to a museum or national park, every educational program in Mauritian schools contributes to supporting them. Paradoxically, the dodo became more useful in death than it would have been alive: its extinction now serves as a constant warning, in Mauritius as throughout the world.

When did the dodo disappear?

The last reliable observations date from the years 1660-1680. The species is considered extinct at the end of the 17th century, less than a century after the landing of the first Dutch settlers in 1598. A recent statistical analysis places the probable date of extinction around 1690.

Could the dodo fly?

No. Its flying ancestors reached Mauritius several million years ago, and in the absence of terrestrial predators, they gradually lost the ability to fly. By the time it was discovered by Europeans, the dodo had vestigial wings, incapable of supporting flight.

Was the dodo really stupid?

No. This reputation stems from a single behavioral trait: the complete absence of instinctive fear of humans, a logical consequence of evolving without terrestrial predators. Historical observations, on the contrary, describe a curious bird capable of learning, and modern reconstructions present it as an agile and ecologically specialized animal.

What is the closest living relative of the dodo?

Nicobar's pigeon (Caloenas nicobaricaThe dodo is a bird with iridescent plumage still found in the islands of Southeast Asia. It shares a recent common ancestor. This relationship was established through molecular genetics in 2002 and confirmed by the complete sequencing of the dodo genome in 2022.

Where can one see a dodo skeleton in Mauritius?

The Natural History Museum in Port Louis houses a skeleton reconstructed from authentic bones found at Mare aux Songes. It's the go-to place for anyone visiting the island. Bone remains are also on display at the National History Museum in Mahebourg.

How much did a dodo weigh?

Modern estimates, based on reconstructions from complete bones, place its weight between 10 and 17 kilograms. The higher figures found in older literature (up to 20-25 kg) probably reflect overfed captive specimens observed in Europe, or individuals in the pre-molt phase with significant fat reserves.

Why did the dodo become the symbol of Mauritius?

Because it is emblematic of the island's natural uniqueness—it existed nowhere else in the world—and because its extinction through human activity profoundly marked Mauritian identity. It appears on the country's coat of arms (adopted in 1906 and confirmed at independence in 1968), on the rupee, and remains omnipresent in local culture.

Where does the word "dodo" come from?

Two hypotheses prevail. For some, the name derives from Portuguese. doudo ("simple-minded"), given by Portuguese sailors because of the bird's lack of suspicion. For others, it comes from Dutch. dodaars ('cul-de-plomb'), referring to its bushy tail. Early Dutch sailors also called it walghvogel ("disgusting bird"), in reference to its unappetizing flesh.

Can the dodo really be resurrected?

Not yet. The complete genome was sequenced in 2022, and the American company Colossal Biosciences is working on a de-extinction project, but considerable technical obstacles remain, and significant ethical questions persist. No dodo is expected to hatch anytime soon, even assuming the project succeeds.

Was the solitaire of Réunion a cousin of the dodo?

Not according to the most recent research. Long considered a close cousin of the dodo, the "Réunion solitaire" is actually a white ibis (Threskiornis solitarius), with no close relation to the dodo. The dodo's true flightless cousin is the Rodrigues solitaire (Pezophaps solitaria), also disappeared, towards the end of the 18th century.

Was the dodo hunted to extinction?

No, contrary to a persistent misconception. Hunting did occur, but it wasn't the primary cause of extinction—dodo meat was considered unappetizing by sailors, who preferred giant tortoises. The decisive factors were habitat destruction (logging) and, above all, the introduction of invasive species (pigs, rats, cats, monkeys) which wiped out reproduction.
