typical Ducks in their small size, and in the shape of the bill, which is throughout of 

 the same width, the tip being subtruncate. The black and green speculum consists 

 of two longitudinal bands, and is present in both sexes. 



Some sixteen species are known, of which one {K carolinmse) is a resident in, and 

 another {N. crecca of Europe) an occasional visitor to, North America. The former 

 alone occurs in Central America, the rest being peculiar to the Old World or to 

 South America.
