EGGS OF BRITISH BIRDS. 73 



THE SOOTY SHEAKWATER 

 (Puffinus griseus.) 



Many specimens of this Shearwater have been recorded as 

 taken in Great Britain, but some of them may have been P. 

 major. The distribution of the species extends nearly all over 

 the seas of the world, but the accounts of it are meagre. Dr. 

 Crowfoot says that on Norfolk Island the holes inhabited by 

 these birds are always isolated, and the burrow deep. One ego- 

 is laid, and there is no nest. 



The eggs, which are pure white, vary from 2" 75 inches to 25 

 inches in length, and from 1*75 to 1*5 inch in breadth. 



BULWEK'S PETBEL. 

 (Bulweria columbina.)* 



Plate 20, Fig. 3. 



One specimen of Bulwer's Petrel has been procured near 

 Tanfield, in Yorkshire, in May, 1857. It is an inhabitant of the 

 temperate North Atlantic and temperate North Pacific Oceans, 

 according to Mr. Salvin, and breeds on the Desertas Islands. 

 Eggs procured by Mr. Ogilvie-Grant in the latter locality were 

 pure white, almost pyriform in shape, and distinctly pointed 

 towards the smaller end. They measure 1*81 to 159 inch in 

 length, and 1*28 to 1*12 inch in breadth. 



THE FULMAB PETBEL. 

 (Fulmarus glacialis.) 



Plate 20, Fig. 5. 



The best known breeding-place of the Fulmar in the British 

 Islands is on St. Kilda and the adjoining Islets and Stacks — a 

 group of rocky islands about forty miles west of the Hebrides. 

 One or two solitary pairs are said to breed on the west coast of 

 Skye, and it also nests on Foula, in the Shetlands. 



The Fulmar is a bird of the North Atlantic Ocean. There are 

 enormous colonies in Iceland, St. Kilda, the Faroes, Spitsbergen, 

 Bear Island, and Novaya Zemlya.
