I've never tried this trap, just read about it in Australia.
This is for catching ducks.
Find water frequented by ducks, with banks. Farm dams, rivers and small creeks work. Dig a trench back from water's edge, just wide enough for a duck, at least 2ft long and 18" deep. Place small amount of grain at end of trench.
Theory goes that a duck goes into the trench and can't walk back out. They aren't good at walking backwards, and their feathers catch.
