 marshes or low-lying lands of any extent in our islands, 

 which do not afford a home to a few pairs of this species. 



It feeds chiefly by night on worms, aquatic insects, 

 water weeds, and grain, and prefers ditches overgrown with 

 weeds or shallow ponds to open stretches of deep water. 

 Early in March it chooses a nesting site, usually on the 

 ground and at no great distance from water, but exceptionally 

 it has been known to nest in trees, faggots, stacks, and 

 other elevated places, l^o nest is formed, but a cup-shaped 

 hollow is scraped out, which is warmly lined with down 

 after incubation commences. The eggs, usually ten to 

 twelve in number, are pale greenish yellow, and are always 

 carefully covered up by the Duck on leaving the nest. 

 They hatch after twenty-seven days' incubation, and the 

 young are then taken to the nearest water, on or near which 

 they remain for about two months till they can fly. If,
