I've narrowed it down to a cockatiel or a conure -- small, but with plenty of personality. Noise level is not a concern. If they want to squawk and sing, that's fine. We'd want a bird who can handle our noise, too -- we're musicians -- and won't mind seeing the dogs lumbering around. If it learns to talk, terrific! If not, I don't care. I'd also want a bird who will be affectionate and want lots of interaction with us. And it would be nice if he or she could eat the same food Clyde or Bonnie eats, so I don't have to buy a third kind of food!
I'm sort of inclined to a cockatiel, but the folks I know that have them have more than one. Do cockatiels need a companion/roommate, or will a solo be okay by him or herself in the cage, with Clyde and Bonnie to talk to when we're gone? Do they like to play with their people and sit on shoulders or are they more aloof than that? Can they eat what budgies or Quakers eat? Do they have any special needs I should know about before I decide?
From the research I've done so far, it sounds as if either species would fit the bill, but those of you who have one or both of these will know more than I do. I wanted to get the conure at Petsmart because I felt bad he/she was stuck living in a pet store, but I just can't swing the $350 price tag plus a cage and toys and everything at one go. I hoped the bird fair would have more reasonable prices. Once I have the bird and cage and all that, I can manage the food and care costs after that for a third bird. And the local avian vet's prices are very reasonable.
