Vol. XXVII—Part VII. April—Sept., 1943. THE Essex Naturalist: BEING THE Journal of the Essex Field Club. THE DUCK DECOYS OF ESSEX. By WILLIAM E. GLEGG, F.Z.S., M.B.O.U. [Read 31st January, 1942.] DECOYS of some kind or other were said to have existed in Britain at the beginning of the thirteenth century and they are known to have given rise to litigation in 1280 and also in 1415 and 1432. In the last-mentioned year a mob armed with swords and sticks took six hundred wildfowl out of the Abbot's Decoy at Crowland Monastery, infringing the rights of private property. Sir R. Payne-Gallwey held the view that the devices used in these earlier days were not decoys, but traps into which the ducks were driven by men in boats. It is believed that decoys as we know them to-day, i.e. with pipes for enticing the birds, were introduced into this country from Holland. The same writer states that we have no reliable evidence that decoys, as now known, even in a primitive form were in use in this country before the middle of the seventeenth century. The earliest and most reliable description of a decoy in England for catching ducks by enticing them is that by Evelyn of the decoy constructed in St. James's Park in 1665. Ray, writing in 1678, speaks of a decoy at that date as a "new artifice" lately introduced by the Dutch and then describes a decoy for enticing wildfowl, much as is now used. The word decoy calls for an explanation. It is an abbreviation of the Dutch term "endekooy," which means Duck Cage. This led to the creation of a compound word, half English, half Dutch, Duck-Coy or "duckoy," as it was spelled at the beginning of the eighteenth century by the owner of Steeple Decoy. It will be seen as this account unfolds that it is no exaggeration to say that Essex plays an important part in the history of British Duck Decoys and that the subject should not be laid aside as one about which the last word has been said. It seems certain that these traps for birds in this country were first used in Lincolnshire and Essex and that the neighbouring counties
