It depends on what you are looking for and how much room you have. Something a little bigger will be more personable, like a cockatiel. Birds have personalities and mannerisms so don't just grab one, find one that wants to interact (like you would with a dog). I would stay away from pet shops, their animals are less socialized than a hand-raised bird will be. You want to find one that's comfortable being held by you before you take him/her. Look for a bird club, they'll know people who raise birds for pets or know of one that needs adopting. You're in southern California, right? I might be able to recommend a club in your area.
Birds are cool but they do need attention and interaction, and can be messy. But the right bird will curl up in your lap like a cat, and after a good head scratch go to sleep. I swear I hear Sidney snore
