Introduced Predators
Definition
Introduced predators are non-native animals brought to penguin habitats by human activity, including rats, cats, dogs, stoats, and ferrets. These predators can devastate penguin colonies that evolved without terrestrial mammalian threats. On New Zealand's mainland, stoats and ferrets are the primary predators of yellow-eyed penguin chicks and eggs. Eradication programmes on sub-Antarctic islands have shown dramatic results: after rats were removed from South Georgia, bird populations including penguins rebounded significantly. Predator control remains one of the most effective direct conservation interventions for penguins.
