FIG. 81. GADWELL. -^natural si/e. 



The gadwell most nearly resembles the mallard, but is not so 

 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. AVhen. 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 

 huffish white eggs are laid.
