In french, cows say "meuh", dogs "ouah-ouah", cats say "miaou", roosters say "cocorico" and ducks say "coin-coin". But in english ? Drop me an email please. I need that for slides I am writing for a forthcoming conference. Thanks !

Update: moo, woof, meow, cock-a-doodle-doo, quack. Many replied, thank to all.
