The Gadwall is by no means a rare bird in any part of India, 

 in the cold weather, generally frequenting the more open and larger 

 tanks in moderately large parties. Its flight is rapid, and its voice 

 not unlike that of the common Duck. It is found over the greater 

 part of the Old Continent, and also in America. It is justly 

 considered one of the best wild Ducks for the table. No other 

 species of Gadwall is recorded.
