My macaw biggles is so friendly towards me and my wife he kisses both of us and loves cuddles. When he's in his cage with just the two of us he's fine but when my grandchildren turn up he gets all mad jumps at the cage at me if I get him out he bites me. As soon as they have gone he goes back to his usual happy loving friend.he stops slamming up the bars at me can someone give me some advice please
