A Twitter user shared a video of his niece and her pet bird stating that the little girl had trained her pet bird to attack people on her command!! And how does she command the bird? By SCREAMING! Anyone she screams at, the bird immediately flies into their head! Check out the video below and get ready for a laugh - the bird doesn't even hesitate! He later shared another photo of the girl with her bird perched on her shoulder, it definitely seems she's found a loyal companion!
