Species Description
The dodo was a large flightless bird, related to modern pigeons and doves, endemic to the Indian Ocean island of Mauritius. One of the Mascarenes Islands (with Reunion and Rodrigues), Mauritius is located in the Indian Ocean, approximately 500 miles east of Madagascar. First discovered by Arab traders in the 13th century, and probably visited by Portuguese sailors in the early 16th century, it was not routinely in use until its acquisition by the Dutch in 1598.

Early drawings of the dodo depict a plump bird, roughly the size of a turkey, weighing approximately 50 lbs. and standing about three feet tall. It had tiny wings, a nine-inch long hooked beak, blue-gray feathers, and short, stout, yellow legs. Contemporary accounts often describe the dodo as clumsy; the name “dodo” reflects this, as it is believed to be derived either from the Dutch word “dodoor” (meaning “sluggard”) or “doudo”, Portuguese for “simpleton”. However, we cannot say with certainty that these early reports are accurate, or that they were even taken from direct observation of birds in the wild. Before the first fossil specimens were uncovered in 1865, very few skeletal elements existed, and there are no known full specimens of the dodo (the last, held in Oxford’s Ashmolean Museum, was destroyed in a fire in 1755). Many descriptions of the dodo are believed to have come from captive specimens, where overfeeding could account for the birds’ large size. In fact, a recently discovered drawing from 1601 depicts a much slimmer bird, estimated to weigh only 33 lbs!

The dodo was flightless, and had highly reduced wings. While most paintings show the dodo along the beach, egg nests were reportedly found inland; given this, the dodo was believed to be a forest or swamp dweller. Though its exact diet is unknown, some accounts claimed that dodos would wade into shallow pools to catch fish, while others say that the dodo subsisted primarily on the fruit of the Tambalacocque, or Dodo Tree. Contemporary accounts also reported that the dodo would frequently eat rocks – these are now believed to have aided with digestion.

While the dodo was certainly used for food by Dutch sailors, and large numbers were shipped back to Europe as specimens, overhunting is not believed to have been the sole cause for the dodo’s extinction. A combination of habitat loss and predation by introduced species decimated an already fragile population, and accounts of live dodos in the wild are scarce starting around 1650. Recent investigations suggest that the dodo was probably extinct by 1693 at the latest, less than 100 years after its discovery.
