93.1. TOWNSEND'S SHEARWATER. _Puffinus auricularis._ This bird ranges from Cape St. Lucas, south along the Pacific coast of Mexico, breeding on the Revillagigedo Islands off the Mexican coast. [Illustration 067: Pink-footed Shearwater. Black-vented Shearwater. Townsend's Shearwater.] [Illustration: right hand margin.] Page 66 94. SOOTY SHEARWATER. _Puffins fuliginosus._ Range.--A common species off the Atlantic coast in summer; breeds along our northern coasts, and it is also supposed that many of them nest in southern seas and reach our coasts early in the summer. These Shearwaters are entirely sooty gray, being somewhat lighter below. They are called "black haglets" by the fishermen, whose vessels they follow in the hope of procuring bits of refuse. They commonly nest in burrows in the ground, but are also said to build in fissures among the ledges. Their single white egg measures 2.55 × 1.75. Data.--Island in Ungava Bay, northern Labrador, June 14, 1896. Egg laid in a fissure of a sea cliff. Collector, A. N. McFord. 95. DARK-BODIED SHEARWATER. _Puffinus griseus._ This is a southern species which, after having nested on islands in the far south during our winter, comes north and appears off the Pacific coast of the United States during the summer. It is a similar bird to the Sooty Shearwater, but is considerably darker and the under coverts are whitish. Their nesting habits are the same as those of other members of the family. Size of egg, 2.40 × 1.65. Data.--Stewart's Island, New Zealand, February 15, 1896. Single egg at the end of a long burrow. 96. SLENDER-BILLED SHEARWATER. _Puffinus tenuirostris._ Range.--Northern Pacific Ocean in the summer, extending from Japan and Alaska southward. Supposed to breed in the southern hemisphere, as well as probably on some of the Aleutians in Alaska. 96.1. WEDGE-TAILED SHEARWATER. _Puffinus cuneatus._ Range.--North Pacific, breeding on the Revillagigedo Islands off the coast of Mexico, and probably on some of the small islands in the Gulf of California. 97. BLACK-TAILED SHEARWATER. _Priofinus cinerus._ This is a Shearwater which inhabits the southern hemisphere, but which has accidentally wandered to the Pacific coast of the United States. It is dark above and whitish below, with black under tail coverts. It breeds in the far south. [Illustration 068: Sooty Shearwater.] [Illustration: Dark-bodied Shearwater.

BLACK-CAPPED PETREL. _Æstrelata hasitata._ This is not a common species; it is an inhabitant of tropical seas and has only been casually found on our coasts or inland. It is a handsome species with white forehead, underparts and nape with a small isolated black cap on the crown; the rest of the upper parts are blackish. It is a native of the West Indies. 99. SCALED PETREL. _Æstrelata scalaris._
