ICELAND GULL 
43. Larus leucopterus. 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.
