THE BLACK GUILLEMOT. 



Uria grylle (Liniic^us). 



The Black Guillemot is chiefly an inhabitant of our northern 

 waters, and its occurrences on the east coast of England or as far 

 south as the Channel are infrequent, even in winter. At the 

 present day it is not known to breed in Wales, but a few pairs 

 resort to the Isle of Man ; while across the Irish Sea it is found in 

 small numbers on the rocky portions of cos. Dublin, Wicklow and 

 A^ntrim, becomes more numerous in the north and west, and can be 

 traced along the south coast to co. Waterford. In Scotland, it 

 appears to have abandoned some localities on the east side where 

 it formerly nested ; but it is common about the cliffs near Dun- 

 cansby Head in Caithness, as well as on the west coast of Sutherland, 

 while it may be called abundant in the Hebrides, especially on the 

 Ascrib Islands in Loch Snizort, Skye. It is likewise plentiful in the 

 Orkneys and Shetlands, where it is generally known as the " Tystie." 



This species breeds in the Fasroes, Scandinavia up to the North 

 Cape, Denmark, and some parts of the Baltic, as well as in the
