They nest on the ground on the islands and shores of Hudson Bay, Greenland, etc. The nest is made of seaweed, grass and moss and is generally quite bulky. The two or three eggs are laid in June. They are of various shades of color from a light drab to a brownish, and are spotted with brownish and black. Size about 3.00 × 2.20.

POINT BARROW GULL. _Larus barrovianus._ Range.--Northwest coast from Bering Sea to Point Barrow. This species is almost identical with the Glaucus Gull, averaging perhaps a trifle smaller. Its standing as a distinct species is still questioned and has not yet been decided satisfactorily. Early in June their nests are built on remote islands in Bering Sea. These nests are the same as the last species, large piles of vegetation, hollowed on top for the reception of the eggs. The eggs have the same variations in color and markings as the Glaucus Gull. Size 3.00 × 2.10. Data.--Herschel Is., Alaska, July 1, 1900. Nest made of seaweed and grass; placed on the ground. Three eggs. Collector, Rev. I. O. Stringer. 43. ICELAND GULL. _Larus leucopterus._ Range.--Arctic regions, south in winter to the Middle States. This Gull in appearance is precisely like the two preceding ones but is considerably smaller; 24 inches in length. A very common bird in the north, breeding in colonies of thousands on many of the islands. It is regarded as one of the most common of the larger Gulls in Bering Sea and also nests commonly in Hudson Bay and Greenland, as well as in the Eastern Hemisphere. They nest indifferently on high rocky cliffs or on low sandy islands. Except when the eggs are laid in a sandy depression in the soil, quite bulky nests are made of seaweed and moss. The eggs are laid about the first of June; they number two to three and have a ground color of brownish or greenish brown and are blotched with umber. Size 2.80 × 1.83. Data.--Mackenzie Bay, Arctic America. June 18, 1899. Nest made of seaweed and grass on an island in the bay.

Range.--North Pacific coast, breeding from British Columbia northwards and wintering from the same country to southern California.
