The skull is conical, stout and heavy, and the teeth, although sharper and less rounded than those of badgers, are less suited to a carnivorous diet than those of stoats, weasels and martens.
The wild animals are bears, wolves, foxes, lynxes, wild cats, badgers, otters, martens, stoats and weasels.
The importation of stoats and weasels, ferrets and cats has resulted in a process of extermination which has already made it necessary to set aside the islets Resolution, Kapiti and Little Barrier as sanctuaries.
And birds of prey, as bears, wolves, foxes, dogs, wild cats, stoats, weasels, eagles, hawks and owls, and never spared by man; even domestic animals, as cattle, goats and reindeer, join in the destruction, stamping them to the ground with their feet, and even eating their bodies.
To check the increase of the rabbit, stoats, weasels and polecats (the last in the form of the domesticated ferret) were introduced into New Zealand on a very large scale in the last quarter of the 19th century.
