On the island of Mauritius once lived a large, flightless bird known as the dodo. With no natural predators, the bird thrived until Dutch sailors led an expedition to the island in 1598, bringing with them ‘alien’ species such as rats, pigs and other domestic animals.
Soon, the bird’s eggs and chicks became staple food for the new arrivals, while habitat destruction decimated its population. By 1680, the last dodo had died.
