Habits. The Wiite-tuiled or Gray Sea Eagle is common to the sea-coast 

 of Europe, where it inhabits only the parts of the country adjacent to the 

 sea, and rears its young on 

 the cliffs. It occurs in Green- 

 land, and is on that ground 

 included in the fauna of 

 North America. It has not 

 yet been traced south of 

 Greenland, nor has it been 

 found in any part of our 

 continent. 



The Sea Eagle in Europe 

 is rarely found inland. It 

 builds its nest on rocky cliffs 

 projecting over the watei', on 

 the shores of Scotland, the 

 Orkney and Shetland Isl- 

 ands, Norway, Eussia, etc. 

 The nest is constructed of 

 sticks, or, %\-]iere these are 

 not convenient, of seaweed. 

 The eggs are two or three in 

 number. Their ground-color 

 is a clear white, usually unmarked, but occasionally stained with small, faint 

 spots of light brown. Tlie measurements of two in my collection, both 

 from Scotland, but obtained at different times by H. F. Walter, Esq., of 

 London, are as follows : Length 2.69 inches, breadth 2.1'.1 inches ; length 2.13 

 inches, breadth 2.25 inches. 



The following, in relation to their breeding and distribution, is taken from 

 Mr. Yarrell's excellent work on the Birds of Great Britain : — 



"The Wliite-tailed Eagle builds its nest on high rocks, and lays two eggs.
