Dried fruits and vegetables are also incorporated into many healthful cockatiel premixed diets. Pass on the brands that contain large amounts of cereal products. Fresh fruits and vegetables are important in the cockatiel diet. Shredded carrots, grated apple or apple chunks, grapes, romaine lettuce, and corn are a few of the foods cockatiels relish. Never offer avocado to any pet bird.
Avocado is toxic to avians and can cause serious illness or death.
You must also never give your bird chocolate or caffeine. If you want to share people' food with your bird, offer rice, pasta, dry cereal, bits of cheese, or scrambled eggs. If you plan on allowing your cockatiel to have play time outside of the cage, you should keep the bird's wings clipped. This procedure is painless and doesn't harm the bird. Ask your veterinarian or pet store personnel to show you how to clip the flight feathers, or have them do it for you.
