48. Larus argentatus Briinn. HERRING GULL. 



An abundant spring and autumn migrant, and winter resident 

 along the coast. Not uncommon on inland bodies of water. In 

 summer, it is now known on our coast only in flocks of presumably 

 barren birds. It is not improbable that it formerly bred in the 

 State, the only record, however, and this, we believe, open to 

 question is of a pair said to have nested on the middle We[e]- 

 pecket Island, Buzzards Bay. in the summer of i888. 2
