Is Charlie a yellow-front?
My husband Charlie had a yellow-front. It was a good bird, until Charlie and his girlfriend had a fight and she went home to her parents with the bird for 6 months, where they spoiled it rotten.
Charlie and his gf got back together and the bird came back but he was very ornery. Charlie put him in his cage one night and apparently he didn't want to go, because when Charlie leaned forward to tell it good night, the bird grabbed hold of his bottom lip.
When Charlie got back from the hospital with stitches, the gf had wisely driven the bird to a friend's house for good.
