The gadwell most nearly resembles the mallard, but is not bo richly coloured, and is smaller in size. It is a widely distributed species, ranging over a greater portion of the northern hemisphere. In the British Islands it is a winter visitor in small numbers, very few pairs remaining to breed, except in one locality in Norfolk, where it has been strictly protected for the last forty years, with the result that it breeds regularly, and is abundant. Elsewhere it is the rarest of the British freshwater ducks. The wings are long and sharply pointed, and the flight exceedingly rapid. When flying it frequently utters its cry, which resembles that of the mallard, but is shriller in tone. Like the mallard, it is a night feeder; during the daylight hours it usually remains concealed in the closest cover. Its nest, lined with dry grass and a quantity of down, is placed on the ground at some distance from the waterside. Eight to twelve buffish white eggs are laid.
