Wild pigs are opportunist scavengers and foragers. Their omnivorous diet includes fern fronds and roots, supplejack, grasses, fruits, native snails, worms and centipedes – and the eggs and chicks of ground nesting birds.
Pigs excavate and kill kiwi in holes or on their nests, and destroy eggs.
Sometimes people deliberately (and usually illegally) release wild pigs so they can hunt them. The consequences for kiwi is a double disaster – not only do they run the gauntlet of wild pigs, hunters’ dogs are also lethal if untrained and uncontrolled.
The Kiwis for kiwi How to Save Kiwi videos has a lot of information on how to trap pigs to help keep kiwi safe.
