3) David Lyall was a lighthouse keeper on Stephen's island, a tiny island off New Zealand. One day in 1894 his cat brought in a dead bird. Mr Lyall didn't recognise the species, so he sent it to England to the famous ornithologist Lord Walter Rothschild. He identified it as an entirely new species, probably the only flightless songbird in the world. He named it in honour of Lyall as Traversia Lyalli, or the Stephen's island wren. But within a matter of weeks, the discovery was followed by the total annihilation of the species. The cat slaughtered all the rest of the wrens, making this the shortest recorded interval between discovery and extinction.
