In the wild, Cockatoos eat whatever they find. For this reason, you should include a variety of things in their diet to stay as close to their natural diet as possible. On the other hand, your cockatoo can eat most of the things that you eat.

They mainly feed on seeds, berries, fruits, nuts and flowers. Sometimes, they can thrive on the basic diet of seeds and pellets alone. They don’t require any particular food but need “particular nutrients”. You should add more vegetables and fruits to your cockatoo’s diet. These are sources of additional nutrition.
