Do ducks eat fish?

Question

we have a creek in our back yard and i was wondering if my two mallard ducks eat fish? we have some small fish so why not?

Answer 1

Mergansers are fish eaters.  They have tooth-like serrations on their bills that help them to hold on to their prey.  They are known locally as saw bills.

Answer 2

Some ducks do, but mallards rarely eat fish.  Mallards, I am sure you don't have the wild type, but the domestic ones eat the same, prefer plants, seeds and grain.

Take a look a your ducks bill.  You see it is not made for catching and eating fish.  Ducks that eat fish are divers.  Mallards are not divers.

Answer 3

they do catch the occasional fish.. but their diet is most grass and water plants
