There are three distinct populations of marbled duck. The first has a fragmented distribution in the western Mediterranean and winters in north and sub-Saharan west Africa. The second breeds in the eastern Mediterranean and winters in Egypt, and the third breeds in western and southern Asia, wintering in Iran, Pakistan and northwest India. A sharp decline has left this species with between 9,000 and 19,000 individuals (2).
Preferring brackish waters, the marbled teal is found on temporary wetlands with plenty of new vegetation (2).
