Population justification: There are thought to be 8,000-10,000 individuals in India, Nepal and Pakistan; 800-1,000 in Cambodia, Laos and Vietnam, 500-800 in Myanmar (unpublished information supplied by Wetlands International Specialist Groups 2006), and in litt. 2005). The population size thus totals 19,000-21,800 individuals, roughly equivalent to 13,000-15,000 mature individuals. |
|
Trend justification: This species's population is suspected to have decreased, owing to the loss and degradation of wetlands, as a result of drainage and conversion to agriculture, ingestion of pesticides, and the hunting of adults and collection of eggs and chicks for trade, food, medicinal purposes and to help limit damage to crops. |
