I'm around my bird, Buzz, all day everyday. During that time I leave the top of his cage open so that he is free to do what he likes. I have placed his cage close to the lounge room, centrally located, so that he can always see me as I go about my daily chores. He loves alot of attention and where he is I am able to talk to him constantly and teach him new words.
If it happens that I do have to go away for the whole day I will always leave the TV on for him so that he has something to listen too as well as to play with his toys in the cage.
