How did humans cause the extinction of Stephen island wren?

Humans caused the extinction of the Stephen Island wren primarily through the introduction of invasive species and habitat destruction. The arrival of cats, brought by lighthouse keepers in the late 19th century, led to the predation of the flightless wren, which had no natural defenses against such predators. Additionally, habitat alteration and degradation further limited the wren's chances of survival. Ultimately, these factors culminated in the species' extinction by 1895.
