278 WHITE SEA-BIRDS. 



Eggs. 2-3, olive-buff, spotted and blotched with 

 brown and gray; 3'0 x 2'1 inches (plate 135). 



Nest. Of dry grass, seaweed, and stalks of weeds 

 growing near, placed on the ground. 



Distribution. As a breeding bird in Dorsetshire, 

 Lundy Island, Cornwall, Scilly, Wales, Isle of Man, 

 the Lake District, and Solway ' flows ; ' more numerous 

 in north-west Scotland, Outer Hebrides, and north- 

 west Ireland. As a visitor at all times round our 

 coasts. 



The Great Black-Backed Gull is in appearance a 

 magnified Lesser Black- Backed Gull. It is far less 

 numerous, and by reason of its greater size, slow, 

 flapping flight, and deeper note, easily distinguished 

 from the smaller bird, the only one with which, 

 because of its similar coloration, it could possibly 

 be confounded. It is a cliff-breeder, affecting rocky 

 coasts and islands ; and the predaceous, carrion-eating 

 propensities of the Lesser Black-Back are accentuated 

 in its larger kinsman. It may also be found on hill- 

 tops and on islets in mountain lakes.
