Lyall's wren

It was described as a distinct genus, Traversia, in honour of naturalist and curio dealer Henry H. Travers, who procured many specimens from Lyall.The lighthouse keeper described the 'rock wren', as he called it, as almost nocturnal, "running around the rocks like a mouse and so quick in its movements that he could not get near enough to hit it with a stick or stone".[7] Its disappearance from the mainland was probably due to predation by the Polynesian rat or kiore (Rattus exulans), which had been introduced by the Māori.Much of what is commonly assumed to be established knowledge about this species' extinction is either wrong or has been misinterpreted, starting with the account by Rothschild (1905) who claimed that a single cat had killed all of the birds.""And we certainly think that it would be as well if the Marine Department, in sending lighthouse keepers to isolated islands where interesting specimens of native birds are known or believed to exist, were to see that they are not allowed to take any cats with them, even if mouse-traps have to be furnished at the cost of the state.
