It's a Bird(1930)

The most mystifying short ever produced!

Charlie, working on a junkjard, always trying to help people in the most impossible ways with junk from his work place, hears from a German professor, that there is a bird, a Belgish Kongo, that eats metal. Charlie sets out on a ridiculous hunting expedition to catch one. With some music - the birds love music - and a strange worm he is able to catch one, but even then the bird offers some even more over-the-top surprises.
