See, when daddy bird gets his paycheck he goes down to the birdy red-light district, hands a whore-bird some money, and spends the night with his penis inside her vagina. Through this act, and the subsequent exchange of bodily fluids, baby bird is born because birds don't have contraceptives.
There you go.
Sex ... obsolete ... stupid freaking idea ...
