Building duck tubes for mallard ducks to nest in is easy and low cost. Andy Stott and Mark Shaw from Westmorland Wildfowlers show how to make them. See exclusive footage of the ducklings in action, leaving their nest and leaping to the water.
With excellent protection from predators and the elements, the ducks love these man-made nests. Just a few tubes around a duck pond can significantly boost the mallard population. More ducklings, more ducks – everyone’s a winner.
