Distribution. India, Ceylon, and Burma in suitable localities , also Africa south of the Sahara, and Madagascar. Common in well-wooded and well-watered parts of the country, rare or wanting in India south of Mysore, in the Bombay Deccan, the desert tracts, Sind and the Western Punjab, also in Tenasserim.

Habits, &c. The Nukta is generally found about large marshy tanks and jheels with reedy margins in well-wooded countries. It keeps in small flocks of 4 to 10 throughout the cold season and in pairs at other times. Larger flocks are said to occur, but they are not often seen. It breeds on trees, and frequently perches on them. The nest consists of a few sticks with dead leaves, grass, feathers &c., placed in a hole in the stem or a depression between the larger branches. The eggs, laid in July, August or September, are ivory-white, very close-textured, 7 to 12 in number, and they measure about 2.41 by 1.72. In Ceylon this Duck is said to breed in February and March. This is not one of the best ducks for the table, though good at times.
