ICELAND GULL 

 43. Lams 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.
