We have a family ducks which have decided to live in our back garden. They have caused the normal vast amount of slugs and snails to almost disappear. This morning the ducklings were fighting over a large slug they had found then the mother barged in and swallowed it whole.
They also get very animated when it starts raining - this must bring out slugs, worms etc. They are not much of a problem otherwise - they don't eat all the greenery as chickens do, and are much more fun to watch.
