Play in HD 1080: Mallard nest tubes. A major mallard hen house project on mainland Britain by the South Cumbria based BASC affiliated Westmorland Wildfowlers Association formed in 1950. For more details see http://www.westmorlandwildfowlersassociation.co.uk/
This video took 3 nesting seasons to produce, and hours of patience to capture the photos and video footage..the ultimate highlight seeing ducklings leaping out of the hen houses!
