I pass shoot ducks occasionally, but prefer to pass shoot geese.
As has been mentioned, find the flight lines, and wait for them to come. We have flooded ex-farm fields, so they typically follow old tile routes. The water is a little deeper, and the cattails die back and it makes silvery ribbons. The ducks follow the lines of open water through the marsh.
As season progresses they learn that the edge of the water is danger. So it's low and fast, sky high, or back in over the dense stuff.
