NORTH AMERICAN BIRDS EGGS. 51 



95. Dark-bodied Shearwater. Puffinus grlseus. 



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 x 

 1.65. Data. Stewart's Island, New Zealand, February 15, 1898. 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 cinereus. 



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. 



[98.] Black-capped Petrel. Mstrelata 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. jEstrelaia scalaris. 



This is another rare species which is an inhabitant of southern seas. A single 

 specimen taken in New York State gives it a claim as a doubtful North Ameri- 

 can species. It is a handsome bird, the feathers of the grayish upperparts 

 being edged with white, thus giving it the appearance of being barred. Its egg 

 have only been known to science within the past few years. Data. Preservation 

 Inlet, New Zealand, June 7, 1900. Single white egg. Size 2.40 x 1.75. Collector, 

 P. Seymour. Parent bird taken with the egg. 



100. Fisher Petrel. JEstrelata fisheri. 



This is a handsome bird known only from the type specimen taken off Kadiak 

 Is., Alaska, by Mr. Fisher.
