It walked on short, ill-shaped legs and had wings and tail so short as to be useless for flight. The birds were once numerous on the island of Mauritius, but it has been two hundred years since the last one was seen. Several perfect specimens are preserved in the British Museum. They furnish the world's sole present knowledge of the bird.
