I once had a cockatiel land on me outside. Lucky for him I already had three at home so I took him home with me and then I had four. He was the loudest, squawkiest bird of the four. He never shut up. It took very little time to realize someone had opened the door and shooed that noise box right out the door. I tolorated him...barely - but he was the happiest of the four...always bebopping, hopping and chattering. He loved my shoulder.
