I have only four times obtained examples of this species for my 

 collection ; the first was caught early in the morning of the 14th of 

 December 1850, on the gallery of the lighthouse, and though 

 perfectly uninjured, made not the least attempt to escape. Two 

 other examples were about the same time shot on the sea, and two 

 besides were seen. In November 1888 three birds were shot, and 

 one was caught alive on the gallery of the lighthouse. 



As regards the nesting stations of this species, Seebohm says : 

 ' So far as is known, there exist only three breeding colonies of 

 this species: one in the North Pacific, which extends from the 

 Kurile to the Aleutian Islands, and two others in the North Atlantic 

 viz. on the islands of the Bay of Fundy, and in the north of 

 Scotland on St. Kilda and Rona Island.' 



380. Storm Petrel [KLEINER STURMVOGEL]. 

 PROCELLARIA PELAGICA, Linn. 



Heligolandish : Liitj Storm-Swoalk = Little Storm Swallow. 

 Thalassidroma pelagica. Naumann, x. 557.

This, the smallest of all the Petrels, visits the neighbourhood 

 of Heligoland in the course of the last three months of every year, 

 and is shot once or twice almost annually. In November and 

 December 1879, which months were remarkably rich in Petrels and 

 Skuas, Aeuckens took as many as eight or ten examples, 

 years like that of 1879 this little bird is much more frequently 

 seen by fishermen some ten to twenty miles out at sea. 



The nesting stations of this species are found on the Orkney 

 and Shetland Islands, the Faroes, St. Kilda, and several < 

 islands on the west coast of Scotland.
