Range in Great Britain. " Leach's Petrel," as this bird is often 

 called, is found on all the coasts of Great Britain in winter, and 

 is often driven inland by storms. It breeds on S. Kilda, and 

 the outer Hebrides. In Ireland a few were found breeding,

Range outside the British Islands. The Fork-tailed Petrel is 

 found in the seas of the Atlantic and Pacific Oceans, inhabiting 

 the temperate waters of the northern hemisphere, as Mr. 

 Salvin puts it.
