Well Tweety Bird is a male. Throughout the cartoon series, Tweety is referred to as him or he. The creators of the character also refer to Tweety as a male. In the movie "Tweety's High Flying Adventure," Tweety even had a ponytailed canary girlfriend named Aoogah.
Boy. I do believe Tweety, like most of the other characters, has a female counterpart. I remember her as a tiny pink bird named Sweety. Or I could have dreamed it, anyone else know who I'm talking about?
