A seed mix for cockatiels is great. Not only does it provide them with nutrition but also they enjoy nibbling and breaking seeds apart. Pellets contain the complete amounts of nutrients for a cockatiel but alone they are boring as they require no work. A mixture of seeds and pellets work best. Millet is another great food for cockatiels. They enjoy picking it off the spray and munching on the little seeds.

Offer your cockatiels fresh fruits and vegetables. Learn which ones they can have and give them some daily. Make sure cockatiels only receive unsprayed plants. Remember to take any fresh foods away when they are not so fresh. They can make the cockatiel sick. It may take your cockatiel a few times before it will eat any new fruits or vegetables. Give them a chance to learn what they like too. A cockatiel eating only seed will end up unhealthy or overweight.

Offer some of the following vegetables daily: asparagus, broccoli, brussel sprouts, carrots, celery, corn on the cob, green beans, kale, peppers, romaine lettuce or spinach leaves(in moderation). Iceberg lettuce has little nutritional value. Make sure everything is thoroughly washed. When eating greens cockatiels may get diarrhea. Make sure they have a mixture of seed and pellets available so they do not over do it with the vegetables as too many can act as a laxative.

Fresh fruits you should also offer are apple, apricots, banana, cantaloupe, cherries, grapes, honeydew melon, kiwi, mango, papaya, peaches, pears, pineapple, plums and watermelon. The seeds from apples, apricots, cherries, peaches, pears and plums are toxic, do not offer them to the bird. Make sure everything is thoroughly washed. Cockatiels also benefit from well-cooked scrambled eggs, especially during breeding season.

Never give cockatiels the following: avocado, chocolate, coffee, lima bean sprouts, milk, soda, sugar or tea. They all may be toxic to your bird. Offer your cockatiel a cuttlebone. It provides calcium, which helps the cockatiel develop strong bones.
