Lyall's wren or the Stephens Island wren was a small flightless passerine belonging to the family Acanthisittidae, the New Zealand wrens. It was once found throughout New Zealand, but when it came to the attention of scientists in 1894, its last refuge was Stephens Island in Cook Strait. Often claimed to be a species driven extinct by a single creature, the wren in fact fell victim to the island's numerous feral cats. The wren was described almost simultaneously by both Walter Rothschild and Walter Buller. It became extinct shortly after.
