The Spot-billed Duck is resident in the southern part of its range from Pakistan and India to southern Japan, but the northern subspecies, the Eastern Spot-billed Duck, is migratory, wintering in Southeast Asia. It is quite gregarious outside the breeding season and forms small flocks. The northernmost populations have expanded their range northwards by more than 500 km in reaction to global warming. It is a bird of fresh water lakes and marshes.
They feed by dabbling for plant food mainly in the evening or at night.
The Spot-billed Duck nests on the ground in vegetation near water, and lays 8-14 eggs.
