Justification of Red List category
This iconic duck of South-East Asia's wetlands is on the verge of extinction. A combination of threats including habitat loss, disturbance and hunting have caused a precipitous decline over the past three generations (26 years), probably exceeding 80%. There are now likely only 150-400 mature individuals left, widely scattered in populations across its once vast range, many of which are probably now too small to be viable. The species likely has an extremely high chance of becoming extinct in the near future. It is therefore listed as Critically Endangered.
