Duck decoy
A device for catching ducks (family Anatidae), consisting of a pond, well screened by bushes and having several backwaters ('pipes') which gradually narrow away from the pond. A trained dog lures ducks from the pond along the pipe, then the decoyman appears behind them and drives them into a trap at the narrow end. A few duck decoys are still in operation to catch ducks for ringing, for example the one in the Wildfowl Trust grounds at Slimbridge in Gloucestershire.From Peter Weaver's Birdwatcher's Dictionary
