Marbled Duck - This duck formerly bred in large numbers in the Mediterranean region, but is now restricted to a few sites in southern Spain and northwest Africa. In the east it survives in Iran , as well as isolated pockets in Turkey, Armenia, Azerbaijan, Iraq and further to the east in western India and western China. Its breeding habitat is lowland, shallow fresh waters. In some areas birds disperse from the breeding grounds, and have been encountered in the winter period in the Sahel zone, south of the Sahara.
