Range (Arctic regions in North)

Arctic regions; in North America migrates south in winter, rarely to Long Island.

Long Island, A. V. in winter.

Nest, of grasses, moss, etc., on the ground. Eggs, clay-color with numerous chocolate markings, 2.79 x 1.89. "The flight of the Iceland Gull, its feeding habits, and its manners generally, suggest a close affinity to the Herring Gull rather than to the Burgomaster" (Chamberlain). 45. Larus kumlieni Brewst. KUMLIEN'S GULL. Very similar in general color to the two preceding species, but differs from them in the color of the primaries. These, instead of being uniformly pure white or but lightly tinted with gray, are marked with sharply defined spaces of ashy gray. The first primary is tipped with white and marked with ashy gray on the outer web and shaft part of the inner web; the second primary is ashy gray on only part of the outer web; the third and fourth primaries have smaller white tips and are marked with ashy gray near their ends on both webs. W., 15-50- 17.00; B., 1.65-1.88; depth of B. at projection on the lower mandible, 60-66; Tar., 2-10-2-35 (Brewster).

Range.-North Atlantic coast of North America; south in winter to Massachusetts.

Nest, on "the shelving rocks of high cliffs." "Mr. Kumlien found this bird breeding in considerable numbers near the head of Cumberland Gulf," but, owing to the difficulty of distinguishing immature specimens from those of L. leucopterus, its status on our coast in winter is not clearly determined. 47. Larus marinus Linn. GREAT BLACK-BACKED GULL; SADDLE-
