My cockatoo has not had a very large diet when i got him he would only eat seed and human crackers, how can I encourage him to eat new foods. I havev been showing him different foods, human and non human foods by having him try them and then putting it into his food dish. he does not seem to be interested in any food other than the pelets that i feed him and and the seed that he is addicted to. For some more info on the bird you can refer to dependent on cage forum.
