Rose bird I don't know the age, but I don't think it matters as long as it's very active and loves to fly, but it doesn't mind or bite if you hold it. It only bites when it's annoyed, you hold it wrong, or you return it to its cage the wrong way. Otherwise, it doesn't bite. As I recall, it's used to strangers. If you tell it to 'bspes', it whistles.
