The dodo bird went extinct in the late 1600s on the island of Mauritius, wiped out by a combination of human hunting and invasive animals brought by European sailors. From first European contact to extinction, the entire process took less than a century, making the dodo one of the fastest documented disappearances of a species in modern history.
Where the Dodo Lived and What It Was
The dodo was a large, flightless bird found only on Mauritius, a volcanic island in the Indian Ocean east of Madagascar. Despite its reputation as a fat, clumsy creature, the dodo was a member of the pigeon and dove family. Its closest living relative is the Nicobar pigeon, a striking iridescent bird found on small islands across Southeast Asia. Genetic analysis shows the dodo’s ancestors were flying pigeons that migrated to Mauritius, where the absence of ground predators allowed them to evolve into a flightless, ground-dwelling species over millions of years.
A healthy dodo weighed around 12 kilograms (about 26 pounds), with a range of roughly 8 to 18 kilograms depending on the individual. That made it approximately five times heavier than the largest living pigeon species. Early European illustrations often exaggerated its bulk, depicting a grotesquely obese bird. Modern skeletal analysis suggests a more proportionate animal than those caricatures implied.
The dodo also wasn’t stupid. A 2016 study that digitally reconstructed the interior of a dodo skull found its brain was exactly the size you’d predict for a bird of its body mass. If brain-to-body ratio is any guide to intelligence, the dodo was about as smart as a pigeon, and pigeons are famously trainable. Researchers also discovered something unusual: the dodo had an enlarged olfactory bulb, the brain region responsible for smell. Most birds rely heavily on vision, but the dodo apparently depended on its sense of smell to find food on the forest floor.
How Europeans Found the Dodo
Portuguese sailors likely visited Mauritius in the early 1500s, but the Dutch established the first permanent settlement in 1598. Sailors arriving on the island encountered a bird that had never seen a predator and showed no fear of humans. That fearlessness made dodos extraordinarily easy to catch and kill.
Contrary to the popular idea that dodo meat was revolting, historical sources indicate sailors found it quite palatable. Records show dodos were regularly hunted for food, including for the island’s governor. One document confirms that dodos were killed for Governor Hubert Hugo as late as August 1673. How many were killed in total is unknown, but the hunting was sustained and widespread enough to significantly accelerate the bird’s decline.
Invasive Species Did the Rest
Hunting alone may not have finished the dodo. The animals that European ships brought to Mauritius were arguably even more destructive. Pigs, rats, crab-eating macaques, goats, and Javan deer all arrived on the island during the 1600s and reshaped its ecosystem in ways the dodo couldn’t survive.
Pigs, macaques, and black rats preyed directly on dodo eggs and chicks. Because dodos nested on the ground, their eggs were completely exposed to these new predators. The adults had no instinct to defend nests against mammals they’d never encountered. Meanwhile, goats and deer destroyed the forest understory, stripping away the vegetation the dodo depended on for food and cover. The combination of losing adults to hunters and losing eggs and chicks to invasive predators created a collapse the species couldn’t recover from.
The Last Sighting
The last confirmed sighting of a living dodo was reported by a sailor named Volkert Evertsz in 1662, on a small islet off the coast of Mauritius. An escaped slave later claimed to have seen one in 1674, and statistical modeling suggests the species may have persisted in small numbers until around 1690. But for practical purposes, the dodo was gone within about 90 years of European arrival on Mauritius.
The speed of the extinction is striking. There was no prolonged decline over centuries, no gradual habitat loss that might have allowed adaptation. A species that had evolved in isolation for millions of years vanished in less than a human lifetime.
A Tree That Nearly Followed It
The dodo’s extinction didn’t just remove one species from Mauritius. It disrupted an ecological relationship that had existed for millennia. An endemic tree called Calvaria major (sometimes known as the tambalacoque) is now nearly extinct itself, because its seeds apparently needed to pass through the dodo’s digestive tract to germinate. The dodo’s gut broke down the seed’s unusually thick outer coating, allowing the embryo inside to sprout. Without the dodo, the tree’s seeds sit dormant, and the species has struggled to reproduce naturally ever since.
What Remains of the Dodo
No complete dodo specimen exists anywhere in the world. The most significant surviving remains are held at Oxford University’s Museum of Natural History: a skull with mummified skin from one side of the head, a foot skeleton, a sectioned thigh bone, and a single feather removed in 1986. This is the only soft tissue from a dodo that still exists, making it invaluable for DNA research. A handful of other museums hold partial skeletal remains, mostly assembled from bones collected in Mauritius over the centuries.
The Push to Bring It Back
A Texas-based biotechnology company called Colossal Biosciences is actively working to “de-extinct” the dodo. The project centers on the Nicobar pigeon, the dodo’s closest living relative. Colossal has established a breeding colony of Nicobar pigeons and has produced high-quality genome sequences for several related species, including the dodo itself from preserved remains.
In a significant technical milestone, the team became the first to successfully cultivate pigeon primordial germ cells, the precursor cells that develop into eggs and sperm. These cells have been sustained in the lab for over two months and, when injected into surrogate embryos, successfully migrated to the reproductive organs. The plan involves editing Nicobar pigeon cells to express dodo-specific traits, then injecting those edited cells into chicken embryos that have been genetically modified to not produce their own germ cells. The resulting chickens would, in theory, produce eggs and sperm carrying dodo-like genetics.
The company has also formed an advisory committee of Mauritius-based experts to guide a potential rewilding program on the island. The project remains in its early stages, and the resulting animal would not be a true dodo but rather a Nicobar pigeon heavily edited to resemble one. Whether it could fill the dodo’s ecological role on Mauritius, including its relationship with species like the Calvaria tree, is an open question.
