Justification of Red List category
This species is classified as Critically Endangered as it is apparently undergoing a 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 hunting and wetland destruction are the key reasons for its decline.
