Justification of Red List category
This species is classified as Critically Endangered as it is apparently undergoing an extremely rapid population decline, as measured by numbers on both the breeding and wintering grounds. It is now absent or occurs in extremely reduced numbers over the majority of its former breeding and wintering grounds and is common nowhere. It is thought that wetland destruction and over-harvesting of both birds and eggs are the key reasons for its decline.

Population size: 150-700

Population trend: Decreasing

Extent of occurrence (breeding/resident): 2,260,000 km²
