PETRELS are dispersed throughout all the seas and oceans of the world. Wilson's Stormy Petrel is one of the best known and commonest. It is to be met with nearly everywhere over the entire watery surface of the globe—far north in the icy regions of the Arctic seas and south to the sunny isles of southern oceans. It breeds in the months of March, April, May, June, July and August, according to the locality, in the northern latitudes of Europe, eastern and western North America. Dr. J. H. Kidder found it on Kerguelen Island, southeast of Africa. He had previously seen the birds at the sea coast off the Cape of Good Hope, and, on December 14, saw them out by day feeding on the oily matter floating away from the carcass of a sea-elephant. The birds, he says, frequent the rocky parts of hillsides, and flitting about like swallows, catch very minute insects. "Mother Carey's Chicken," as it is called by sailors, is widely believed to be the harbinger of bad weather, and many superstitions have grown out of the habit which they possess of apparently walking on the surface of the water as the Apostle St. Peter is recorded to have done. It is the smallest of the web-footed birds, yet few storms are violent enough to keep it from wandering over the waves in search of the food that the disturbed water casts to the surface.

The Stormy Petrel is so exceedingly oily in texture, that the inhabitants of the Ferol islands draw a wick through its body and use it as a lamp.

Wilson gives the following account of its habits while following a ship under sail:

"It is indeed an interesting sight to observe these little birds in a gale, coursing over the waves, down the declivities, up the ascents of the foaming surf that threatens to bend over their head; sweeping along through the hollow troughs of the sea, as in a sheltered valley, and again mounting with the rising billow, and just above its surface, occasionally dropping their feet, which, striking the water, throws the birds up again with additional force; sometimes leaping, with both legs parallel, on the surface of the roughest wave for several yards at a time. Meanwhile they continue coursing from side to side of the ship's wake, making excursions far and wide, to the right and to the left, now a great way ahead, and now shooting astern for several hundred yards, returning again to the ship, as if she were all the time stationary, though perhaps running at the rate of ten knots an hour! But the most singular peculiarity of this bird is its faculty of standing and even running on the surface of the water, which it performs with apparent facility. When any greasy matter is thrown overboard these birds instantly collect around it, and face to windward, with their long wings expanded and their webbed feet patting the water, which the lightness of their bodies and the action of the wind on their wings enable them to do with ease. In calm weather they perform the same maneuver by keeping their wings just so much in action as to prevent their feet from sinking below the surface."

Rev. Mr. Eaton says that this species nests under large rocks not far from the beach. Egg, one, white.
