A duck decoy is a device to capture wild ducks or other species of waterfowl. Formerly the birds were slaughtered and used for food. More recently they have also been used for ornithological research.

Etymology

The word decoy is derived from the Dutch word eendenkooi, which means "duck-cage";^[1] Chambers Dictionary suggests Dutch de kooi = "the cage".

Description

As finally developed the decoy consisted of a pool of water leading from which are from one to eight curving, tapering ditches. Over each ditch is series of hoops, initially made from wood, later from iron, which diminish in size as the ditch tapers. The hoops are covered in netting. The combination of ditch and net-covered hoop is known as a pipe. On the outside curve of the pipe, for two-thirds of its length, are overlapping screens.^[2]

Operation

There are two methods of working a duck decoy, dogging or feeding.

Dogging

Dogging

Ducks are naturally curious and when they see a predator, such as a fox, they will keep it at a distance, but tend to follow it. The decoy man uses a dog, preferably a breed similar in appearance to a fox, to lure the ducks along the pipes. For this purpose was in the sixteenth century in the Netherlands the kooikerhondje breed developed. The dog appears between a gap in the screens and the ducks approach. It then appears at the next gap further along the pipe, and so on until the ducks are trapped at the end of the pipe.^[3]

Feeding

The decoyman walks behind the screens, throwing grain or other food over them while keeping out of sight. The ducks follow, eating the food, and are caught at the end of the pipe.^[4]

Today

England

In the mid-1880s there were 41 decoys still in operation in England, and 145 which were no longer in use.^[5] Today there are only a few remaining duck decoys in England. These include Hale Duck Decoy in Cheshire, administered by Halton Borough Council,^[6] Boarstall Duck Decoy near Aylesbury in Buckinghamshire, owned and administered by the National Trust,^[7] and a decoy in Abbotsbury Swannery, Dorset.^[8]

Some are used to trap ducks for non-harmful study, such as ringing them.^{[citation needed]}

Evidence of former duck decoys can be found. At Swanpool near Lincoln, cropmarks revealed in aerial photographs show the outlines of a decoy.^[9] In Somerset, west of Nyland Hill there is evidence of a pond with three pipes,^[10] and in Westbury there is a decoy with possibly six pipes.^[11]

Netherlands

There are about 111 decoys still in operation in the Netherlands,^[12] the oldest one dating from the 13th century.^[13] The number of ducks still caught for consumption is small. Larger numbers of ducks are hunted by shooting. The decoys are mostly used for study purposes including ringing, but also for studying the avian flu.^[14]

Denmark and Germany

On the North Frisian Islands, decoys originally served as a pastime for sea captains and ships' officers during wintertime. Later the ponds were also used to trap great numbers of wild ducks for commercial purposes. In one decoy on Föhr island, more than 3,000,000 ducks have been caught since its installation in 1735, and from 1885 to 1931 a factory for canned duck meat was active in Wyk auf Föhr. The preserved meat was exported worldwide. Today there are six inactive decoys on Föhr.^[15] Another decoy is located near Norddorf on Amrum island.^[16] The decoy on Pellworm island was active until 1946. Today it is a public park and has been converted into an orchard.^[17]
