Though breeding in Norfolk under protection, the 

 Gadwall is generally known as a rather rare winter 

 visitor to our islands. It associates in flocks, and 

 haunts for the most part fresh-water lakes, skulking 

 by day in the herbage, and feeding by night It 

 is little seen on the coasts. The Gad wall's pointed 

 wings give it a rapid flight, more so than that of 

 the Mallard, which in its note and appearance it 

 resembles more nearly than any other Duck. Its 

 food consists chiefly of aquatic plants and weeds. 

 The characteristic markings of the Gadwall are the 

 chestnut and black wing-patches, the white speculum 

 both in the male and in the female, though reduced 

 in the latter. The male suffers the usual summer 

 eclipse in its plumage, becoming at that time like the 

 female, but darker.
