The Stephens Island wren (Traversia lyalli), also known by the name of Lyall's wren, was a small passerine bird belonging to the family of New Zealand wrens. The last living specimen of the bird was known to be found in Stephens Island in the Cook Strait.
However, the Stephens Island wren was once known to exist everywhere in New Zealand.
The birds have seen an extinction event because of the lighthouse keeper's cat named Tibbles. When the lighthouse was made in Stephens Island, Tibbles the cat along with her master, David Lyall, the assistant lighthouse keeper, and 16 other people arrived at the island.
David Lyall was a naturalist and was keen to explore the island which at the time was unseen.
However, bringing along the lighthouse keeper's cat was a huge mistake as Tibbles was also pregnant at the time. All the lighthouse keepers were at fault and did very little in protecting the new species that they discovered.
Although everyone believes that Tibbles, the lighthouse keeper's cat killed the new species of bird found on the island, the actual reason for extinction might be the infestation of the feral cats on Stephens Island.
The discovery of the nocturnal and flightless species of bird called the Lyall's wren goes to Lyall, one of the lighthouse keepers of the islands. His cat brought him specimens and he could recognize most of the species, except one.
On the verge of a new discovery, he sent few specimens to Walter Rothschild, Walter Buller, and H. H. Travers.
The natural history of the earth has taught us many a time that cats have killed many species of birds and other animals throughout. The cats have pushed many species towards extinction, and the most dangerous thing about these animals is that they kill even when they are not hungry.

Did you know...
David Lyall, the lighthouse keeper, believed that the flightless bird was like mice, running around on the rocks so fast that he could not catch it or kill it.
As Lyall, one of the lighthouse keepers and the owner of the cat that killed the birds found an unknown species, he sent the specimens to renowned ornithologists Walter Rothschild, Walter Buller, and H. H. Travers.
Walter Rothschild bought few specimens from Lyall for extensive research and Walter Buller recognized the specimens as a distinct species and wrote a scientific description for the journal. It was Walter Rothschild that gave the scientific name Traversia lyalli to the birds after the lighthouse keeper Lyall who discovered the species and H.H.

Natural history and discovery of fossils of the bird in New Zealand found that the bird species actually roamed around the whole country and later settled in the island's habitat. But the hunting tactics of the lighthouse keeper's cat wiped out the whole population of the Lyall's wren in just a year.
For the death of the last Stephens Island wren, a cat named Tibbles who was the lighthouse keeper's cat was given the blame.
However, the extinction event went on for more than two years, and many feral cats of the island were found to be the reason for wiping the Lyall's wren out of existence.
Now some specimens of the bird from the islands can only be seen in museums. Fifteen of the specimens are found in museums all over the country.
