Despite the perceptions that people may hold, owing to the long eyelashes and high pitched voice (which Mel Blanc provided), Tweety is male although his ambiguity was played with. For example, in the cartoon Snow Business, when Granny entered a room containing Tweety and Sylvester she said: “Here I am, boys!”, whereas a 1951 cartoon was entitled Ain’t She Tweet [emphasis added]. Also, his species is ambiguous; although originally and often portrayed as a young canary, he is also frequently called a rare and valuable “tweety bird” as a plot device, and once called “the only living specimen”. Nevertheless, the title song of The Sylvester & Tweety Mysteries directly states that the bird is a canary. His shape more closely suggests that of a baby bird, which is what he was during his early appearances (although the “baby bird” aspect has been used in a few later cartoons as a plot device). The yellow feathers were added but otherwise he retained the baby-bird shape.
