Yes. Generally, most macaws are monogamous and mate for life. This is why pet macaws tend to form a special bond with one person. If they outlive that person or if they are re-homed to somebody else, they are simply devastated.
Cockatiels do not need anything to have a mate. Just put him/her in the cage with your cockatiel, however, if you want them to mate, they will not mate if you do not have a nesting box. In order to breed cockatiels, you will need a nesting box.
