Range. - North Atlantic coasts from New England northward, breeding from Hudson Bay and southern Greenland northward.

This bird which is 19 inches in length, in the light phase has a plumage very similar to that of the larger Gulls. They nest by thousands on rocky islands of the north, often in company with Murres and Gulls. Owing to the filthy habits of the Fulmars, these breeding grounds always have a nauseating odor, which is also imparted to, and retained by the egg shell. Their single white eggs are laid on the bare rocks, in crevices of the cliffs, often hundreds of feet above the water. Size 2.90 x 2. Data. - St. Kilda, off Scotland. June 5, 1897. Single egg laid on rock on side of sea cliff. Collector, Angus Gillies.

86 Fulmar Fulmarus Glacialis Glacialis 160

86b. Pacific Fulmar. Fulmarus Glaci-Alis Glupischa

This sub-species of the preceding, has a darker mantle than the common Fulmar; it is found on the northern Pacific coasts where it breeds on the high rocky cliffs, the same as it's eastern relative. They nest in large colonies, every crevice in the rocks having its tenant. Their flight is graceful like that of the Gulls, which they closely resemble. They lay but a single white egg, the average dimensions of which are slightly smaller than those of the common Fulmar. Data. - Copper Is., Alaska. May 14, 1889. Egg laid in a crevice among the cliffs.

86.1. Rodger's Fulmar. Fulmarus Rodgers

Range. - North Pacific, breeding in large numbers on some of the islands in Bering Sea; south to California in winter. Very similar to the two preceding species except that the back is mixed with whitish, it is not believed to have a dark phase. Their breeding habits and eggs do not differ from the common Fulmar. The eggs are laid on the rocky cliffs during June.
