Of course he will! All parrots are highly social and they NEED companionship so getting them to want to be with us is nothing more than a matter of us being kind and in giving them enough time to realize they can trust us.
Cockatiels are, in my personal opinion, the best-tempered of all parrots. They are sweet, sweet, sweet and one doesn't really have to do much to get them to trust - just treat them right and they will. I used to have a large flock of them living cage-free in my birdroom and they would perch on my shoulder and head all the time even though I never even initiated any kind of interaction with them. Liz has a small flock and they have all grown to trust and love her, too. The difference between companion and aviary species is that companions bond very deeply with humans while aviary birds would much rather be with another bird of their own species (or a similar one) than with a human once they become sexually mature but, if they have nobody else, they will be eager for our company. Of course, personally, I would not keep a single bird of an aviary species, I would get it a mate, but you can't go by me. I am not 'into' pet birds and I couldn't care less if they are trained or not, I just want them to be healthy and happy and if that means the bird will not bond with me, it's fine! I am happy if they are happy.
