Kiwi birds in New Zealand face several introduced predators. Stoats are the most significant threat and have driven the decline of many kiwi populations. Cats also prey on kiwi, though they are less widespread. Dogs can kill kiwi, especially in urban areas, and ferrets pose a smaller but still real danger.
Weka, a native flightless bird, occasionally kill and eat kiwi eggs, though they are not typical kiwi predators.
