lines." (Note. The Red-legged Black Duck (Anas obscura rub- 

 npes), a larger race, occurs here in migration and Winter, but it 

 is impossible to tell them apart in the field. ) 

 14- GREEN-WINGED TUAh—Ncttion carolinensis. 

 Rare Fall migrant on marshes, occasionally winters. 



15. BLUE-WINGED TEAL—Qucrquedula discors. 



Rare Fall migrant on fresh water ponds and salt marshes.

 marshes, altho Mrs. Mabel Osgood Wright gives it as common

18. RED HEAD— Aythya amcricana. 

 Very rare Fall migrant on salt water. 



19. AMERICAN SCAUP T>UCK— Aythya mariia. 

 Common Winter resident arrives October, most leave in 



April. This duck is extremely common on the Sound in early 

 Spring, gathering in large rafts some distance off shore. They 

 come up into the harbor farther than the Scoters but not so far 

 as the Golden-eye. A few Scaups remain on the coast till June, 

 and are the last migrant ducks to leave. These birds are prob- 

 ably the Lesser Scaup Duck, but there is no way 

 of telling them from the larger form in the field. Woodmont, 

 Savin Rock, Lighthouse Point, Momauguin, Lake Saltonstall. 



(a). LESSER SCAUP DUCK— Aythya affinis. 

 Rather rare migrant and Winter resident. See No. 19.

 clangula americana.

 middle of x'\pril. Comes well up the harbor and stays well in 

 shore, has been seen at City Point, Woodmont, Savin Rock, 

 Sandspit, Harbor, Lighthouse Point, Momauguin, Lake Salton- 

 stall.
