NORTH AMERICAN BIRDS. S3 



This is an Eastern Atlantic species of which no American specimens are known 

 to exist in collections at the present time. ' A. series ol four sets of one egg each are in 

 Mr. Crandall's collection. The first was taken June 21st, 1890, on Porto Santo 

 Island, one of ; the Maderia group. The egg measures 3.02x1.95. The second was 

 taken in one of the islands of the same group July 5th, 1891; th« specimen measures 

 2.87x2.01; another, collected June 21st, 1893, on Porto Santo Island, measures 2.90x 

 1.90. The fourth was taken July 18th, 1893, on Desertas Island, of the Maderia 

 group, apd its size Is 2.90x1.80. Three of the specimens are. quite pointed, hut the 

 fourth is of a well-rounded type like those of the alhatrosses. The Cinereous Shears 

 water's eggs are of exceedingly hrilllant whiteness, and although little pits appear 

 regularly over the shell, the texture is very fine. They are by far the handsomest 

 white sea birds' eggs, and for this reason can easily be differentiated from those of 

 the Fulmars. This species nests in the holes and crannies o£ cliffs. 



98. BLACK-CAPPED PETREL, ^sfrelata hasitata (Kuhl.) Geog. Dist.— 

 Warmer parts of the Atlantic Ocean; accidental in Florida, Long Island, England 

 and France. , ' - 



We know nothing concerning the nesting and eggs of this species, which is ot 

 casual occurrence on the Atlantic coast of the United States. 



99. SCALED PETBEL. ^strelata scalaris (Brewst.) Geog. Dist. — Unknown; 

 accidental in Western New York. 



A specimen of this species was caught in New York State, Livingston county, 

 April, 1880. Its geographical range, habits, eggs and nesting are unknown. 



100. FISHER'S PETREL, ^strelata flsheri (Ridgw.) Geog. Dist.— Coast of 

 Alaska. 



This species was described by Mr. Ridgway from a specimen taken on Kadiak 

 Island by Mr. Fisher. (See Proc. U. S. National Museum, 1882, pp. 656-658.) Nothing 

 distinctive is known of its habits. 



101. BULWER'S PETREL. Bulweria hulweri (Jard & Selby.) Geog. Dist. — 

 Eastern Atlantic, including coasts of Europe and Africa. 



This petrel is known to breed on the Canary and Madeira Islands and others on the 

 northwestern coast of Africa. It is said to be an occasional visitor to the Bermudas 

 and accidental in Greenland. It n^sts in burrows in the soft earth under overlying 

 boulder-rocks and in deep crevices in cliffs. The bird is stated to be nocturnal in its 

 habits, never flying about in the daytime. The single egg which this species lays is 

 oval in shape, equal-ended, and pure white in color; sizes range from 1.59 to 1.76 long, 

 by 1.17 to 1.23 broad. 



102. PINTADO PETBEL. Daption capensis (Linn.) Geog. Dist.— Oceans of 

 the Southern Hemisphere, north to about latitude 25°. Accidental on the coasts of 

 California and England. 



This petrel inhabits the Southern seas generally. It is known as the Cape 

 Pigeon and Damier. Its eggs are at present unknown. The shape of the bird very 

 much resembles that of a pigeon, as will be seen by the illustration.
