Nesting success of Mallard Anas platyrhynchos was evaluated at Haigam, Hokarsar and Shalabug lakes in Kashmir in 2012 and 2013. Nests were located, tagged and monitored until the clutch hatched. Nest location, nest volume and height above water/ground measured, and threats were all noted. A total of 95 nests with 556 eggs within tree holes, willow root mats or reed beds were monitored. Nests in which at least one egg hatched were deemed successful. A logistic regression was used to identify variables associated with nesting success over two years. Nesting success was 53% and hatching success 64%. Nesting success was significantly higher within tree holes due to lower risk from flooding and human disturbance. About 27% of nests were affected by human harvesting and 16% by flooding.
