MaHnus^oi the sea. 



Distribution in the British Islands. — A Resident, breeding on 

 the coasts and outlying " stacks," also inland and on islands 

 in lakes. It is found locally and in small numbers on the 

 ■south-west and west of England and Wales and the Scilly 

 Islands, commonly in Scotland and Ireland, and on the 

 ■islands to the west and north. The largest colony in our 

 Islands is probably that on the Holm of NosSj Shetlands. 

 In winter it is widely distributed on all our coasts. 



General Distribution, — The Greater Black-backed Gull 

 breeds in Iceland, the Faeroes, and north Europe, east to 

 •the lower Petchora and probably to the Yenesei, and south 

 to about 50° N. latitude on the north-west of France : also 

 in Greenland and North America from North Devon Island 

 southwards through Labrador to Maine and Nova Scotia. 

 In winter it occasionally visits the Mediterranean and Black 

 seas as well as inland waters in small numbers ; also the 

 Canary Islands and the Azores ; in America it occasionally 

 'i-auges south to the Bermudas and to Florida.
