However, it often attacks sheep and even jumps on their backs. Its strong beak can pierce the skin and beak of sheep, devour the fat on the kidney of sheep and peck at the mutton, making the live sheep bloody, so the local herdsmen in New Zealand call it a sheep pecking parrot. They are complete opportunists. Every spring, this sheep-pecking parrot digs daisies on high mountains and looks for new plant buds or small insects around snowdrifts and crevices in rocks. In summer, look for fruits or berries, seeds and flowers in the bushes on the mountain. In autumn, most of them will stay in the beech forest and feed on some buds, leaves and nuts; But in the harshest season of winter, they will look for the remains of dead animals and dig out the most dynamic internal organs and fat parts to eat in order to survive the harshest test of nature.
Kaka's parrot eats fruits, seeds and nectar in forests and flowers all day, but sometimes it attacks sheep's young, so it is called "sheep killer", but in fact only some individuals are used to attacking young sheep. The local aborigines didn't retaliate against Kaka's parrot, and sometimes they abandoned the rest of the mutton to them. In this way, Kaka's sheep-pecking parrot has been living in peace with the local aborigines.
