Where would you find a quack?

Many many ducksI suggest you go to a pond/lake/river near you and there should be several ducks. The bigger the lake, the more ducks there are. OR in an area where they migrate to.

Look for an area with a small pond: ducks don't like deep water. Also look for a pond with cattails lining its shore. They like to hide in the cattails.

But the truth is is there is no one type of environment ducks like to hang out in. Really, it depends on the personality of the individual duck.
