Distribution in the British Islands. — A Eesident, inhabiting 

 suitable rocky coasts from April until autumn. It is 

 common in the Shetland and Orkney Islands, the Outer and 

 some of the Inner Hebrides, as well as the north and west 

 coasts of Scotland, but becomes scarce and local towards the 

 Solway Firth and the Isle of Man. It no longer breeds in 

 Wales, or on the east coasts of Scotland and Yorkshire, and 

 is rarely met with off the south coast, even in winter. In 

 Ireland it is tolerably plentiful, especially on the north and 

 west coasts. In winter it is found o£E the coasts of its 

 breeding-range. 



General Distribution. — The Black Guillemot breeds in 

 north Europe from the White sea westwards to Scandinavia 

 and south to Denmark; also in the Faeroes, Iceland, south 

 Greenland, and eastern North America from Labrador to 

 Maine and Newfoundland. In winter it ranges occasionally 

 to the north of France and to New Jersey. In the circum- 

 polar seas an allied form is found ranging south to Labrador, 

 Norton Sound, Alaska, Kamchatka, and north Siberia.
