It was the last animated short film produced by Walt Disney Animation Studios to win an Academy Award, until Paperman (2012).
As producer of "It's Tough to Be a Bird", Ward Kimball became the only one of Disney's famed "Nine Old Men" animators to win an Oscar.
This was released in the UK as a support/double feature with 'The Boatnicks'.
Donald Duck (in a quick appearance among multiple bird pictures), clips from the Silly Symphony cartoons, and Mary Poppins (at the end of the film) made cameo appearances.
