Pluto's Fledgling (1948)

Continuity mistake: When we first see the baby bird in its nest at the beginning of the cartoon, you can see that the nest is positioned on a branch, but when we see the bird attempting to fly later on, the nest is now in the crook of two branches.

Trivia: When Pluto is walking up a pile of logs in order to return the bird to its nest, look carefully and you can see that the end of three logs form a "Hidden Mickey."
