A common species on some parts of the British coast, especially northwards. Very abundant in the Orkneys and Hebrides, where it breeds in holes in the ground or in the clefts of rocks, laying one, sometimes two eggs. Generally keeps far out at sea, though occasionally driven inland by storms. Individuals under such circumstances, have been met with in various parts of England. Skims the surface of the ocean, feeding on the marine insects which float on the waves. When approached, ejects from its mouth an oily substance of a very rancid smell.
