FOOD Even where there is no native forest, fantails, riroriro and ruru can find insects in gardens. Tui and bellbird can sip nectar from garden flowers as well as from native flowers. Silvereyes eat nectar, insects and garden fruit. Seagulls can find food at the rubbish dump as well as in the sea. So all these birds can live in places where people are living and native forests are gone. But kakapo and kokako can't. They need native forest for their flowers, fruits and leaves and often these are eaten by possums. Also, people keep cutting the forests down This means they have no food to eat, and they die out.
