The Lyall’s wren was a species of small, flightless birds that once thrived on Stephens Island, in New Zealand. It’s one of the many species that have been rendered extinct by the reckless introduction of predators in their natural habitat, but what makes this bird’s story unique is that it was allegedly both discovered and wiped out by a house cat named Tibbles.
The lighthouse on Stephens Island was built in 1892, but the existence of a yet-undiscovered species of bird on this small patch of land was only reported a couple of years later, when assistant lighthouse keeper David Lyall moved in, along with a small staff and his pregnant cat, Tibbles. Lyall was a passionate naturalist and amateur ornithologist, and was looking forward to pursuing his hobbies on this previously uninhabited island, but little did he know that he would go down in history as the man who discovered the Lyall’s wren and indirectly caused its extinction, both in less than a year.
