Range.—Breeds from Labrador and Hudson Bay northward; winters south to New England, the Great Lakes and Calif.
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 ungainly 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.
