A breed of duck from Bourbourg in Nord-Pas-de-Calais near the Belgian border. It is descended from the white Aylesbury duck of England and the Mertchem duck of Belgium and appeared around the end of the 19th Century. Not much interest being shown in it the breed nearly died out in the mid-20th Century but it is now a rare breed duck of some interest with the standard established in 1824. Like the Aylesbury it is itself white, with a large body, stands in a very horizontal position, has a pinkish-white bill and orange-yellow legs.
