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 1952 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.
