Bird Invaders

Birds. For centuries we have oppressed them, grilling, roasting, stewing, and stuffing them in buns. We should have known the time would come for us to pay. And it did.

Intergalactic Birds invaded Earth, seeking revenge for the oppression of their earthly brethren. They came out of nowhere, and everywhere. It was only you who managed to repel the invasion, and saved humanity from an eternity of servitude.
