Laysan Rail
The Laysan Rail was a small flightless bird that was native to the Hawaiian island of Laysan. It was known for mating cries that sounded a lot like a mechanical alarm clock. The bird’s population dropped off rapidly during the first half of the 20th century – it was believed to be extinct as early as 1923, but any remaining birds ultimately suffered during World War II, and a final sighting occurred in 1944.
