Seeds of Polygonum spp., especially P. convolvulus, were the main weed seeds eaten by partridges in October 1968 and formed 44% of the total dry weight of dicotyledonous weed seeds in the diet. Polygonum spp. were preferred to other weed species in the stubble flora. Polygonum spp. populations have been reduced as a result of improved crop husbandry techniques and it is expected that this will reduce their contribution to the diet.
