If you want the colorful companionship of a parrot without having to sacrifice an entire room of your home to provide adequate space, then you might consider a Parrotlet. These are the smallest parrots, so they don’t need too much space.
What they do need is a lot of attention. They’re naturally friendly birds, but they’ll become less friendly very quickly if left alone. If you provide plenty of attention from the start, your Parrotlet will bond closely with you. But if you give your Parrotlet a partner, they’ll bond with each other instead of you.
