The fulmar petrel is a near ally of the giant petrel. The fulmar,
Fulmaris glacialis, reaches a length of about 19 inches, and though very variable in color, usually has the head, neck, and under surface white, and the back pearly gray, with darker wing quills. It is a northern bird, and breeds in thousands on the Hebrides and other subarctic islands and coasts. It is known to sailors as "mollemoke." Only a single egg is laid, and there is practically no nest. A similar species occurs in the northern parts of the Pacific and in Bering Sea.
