ICELAND GULL 



43. Larus leucoptcrus. 25 in. 



Plumage exactly like that of the Glaucus Gull but 

 the birds are smaller and are found farther north. 



Range. Breeds in Greenland and winters south to 

 Northern New England and the Great Lakes. 



KUMLIEN GULL 

 45. Larus kumlieni. 27 in. 



Plumage very similar to that of the Iceland and 

 Glaucus Gulls, but with the primaries conspicuously 

 gray, with white tips. As usual with the gull family, 

 this species feeds largely, during the nesting season 

 upon eggs and young, of other sea birds. They seem to 

 have a special liking for Cormorant eggs, and' these un- 

 gainly creatures have to sit on their nests very closely 

 to prevent being robbed. 



Range. Breeds about the mouth of Hudson Bay; 

 winters south to Long Island.
