AMERICAN SCAUP DUCK 



148. Marila marila. 18 in. 



Head black, glossed with greenish; speculum white; 

 bill dull bluish; eye yellow. Female resembles that of 

 the Redhead, but has a white speculum. These ducks 

 are perhaps better known as Blue-bills, than as Scaup 

 Ducks. They are one of the most abundant migrants 

 on the Atlantic coast, and are one of the most active of 

 the family, diving at the flash of a gun. 



Notes. A peculiar grunting quack. 



Nest. Of grass and feathers on the ground in 

 marshes. 



Range. Breeds from Minnesota and Dakota north- 

 ward. Winters south of New England. 



LESSER SCAUP DUCK 



149. Marila affinis. 17 in. 



Slightly smaller than the last, and with the head of 

 the male glossed purple instead of green. 



Range. Breeding range same as that of the la*t: 

 winters in the southern half of the U. S.
