Lighthouse keeper's cat that exterminated a rare bird species

(autotranslated, could have mistakes)

Often we (people) systematically become the cause of the extinction of various species of animals, but in history there have been rare cases recorded when the same thing happened due to the fault of a representative of the animal world.

For example, the Stephens Bush Wren (a type of nocturnal, extinct, flightless bird) was, according to legend, destroyed by a single wild cat named Tibbles, who was tamed by the lighthouse keeper on Stephens Island (New Zealand).
