From Gustible's Planet — Cordwainer Smith

When space explorer Angary Gustible stumbles upon a planet of telepathic duck people, hilarity and intergalactic tension ensue. The inhabitants embarrass Gustible by dramatizing his personal life and follow him back to Earth with appetites for human cuisine. This satirical sci-fi explores the trials of first contact, cultural misunderstandings, and the limits of diplomacy when both species find the other quite tasty.
