What it is
The Lord Howe swamphen (Porphyrio albus), also called the white swamphen, was a stocky, flightless bird with mostly white feathers and a heavy red bill. Only two skins survive, in Liverpool and Vienna. The International Union for Conservation of Nature lists it as Extinct.
Range
Lord Howe Island, in the Tasman Sea east of Australia.
What happened
Crews of the first ships to visit the island in 1788 found the birds tame and easy to kill. Whalers and sealers who stopped for food probably hunted them out before settlers arrived in 1834.
When / status
Probably gone before 1834.
Human role
Hunting by visiting sailors probably drove it to extinction.
