The dodo (Raphus cucullatus) was a flightless bird endemic to the Indian Ocean island of Mauritius. Related to pigeons and doves, it stood about a meter (3 feet) tall, weighing about 20 kilograms (44 lb), living on fruit, and nesting on the ground.
The dodo has been extinct since the mid-to-late 17th century. It is commonly used as the archetype of an extinct species because its extinction occurred during recorded human history and was directly attributable to human activity.
The phrase “dead as a dodo” means undoubtedly and unquestionably dead, whilst the phrase “to go the way of the dodo” means to become extinct or obsolete, to fall out of common usage or practice, or to become a thing of the past.
