Dodo
The dodo was not scared of people which made it easy to hunt and kill. Dogs, cats, rats and pigs were left on the island and also killed the dodos. Because dodos built their nests on the ground, the new animals ate their eggs. The forests were chopped down and the dodo lost its habitat. Within 80 years, the dodo was extinct. The last confirmed dodo sighting in Mauritius was 1662, but a 2003 research by David Roberts and Andrew Solow estimated that the dodo lived another few decades unnoticed until around 1690.
