The dodo and the Rodrigues solitaire are two famous flightless birds on the Mascarene Islands in the Indian Ocean, east of Madagascar. They are extinct, but were alive before sailors found the islands. They had no fear of humans, whom they had never seen. The sailors hunted them, and killed them for food. Both species are now extinct. Animals introduced by man may also have hunted them. Their anatomy (osteology) and DNA sequence analyses show they were are in the Columbidae.
