SO distinctly on the crown itself; entire back, scapulars, and 

 median wing-coverts bright fulvous-brown, with large markings 

 of dark brown towards the tips, imparting a strongly mottled 

 appearance to the upper surface of the body : lesser and greater 

 wing-coverts dark brown, the latter slightly mottled with whity- 

 brown, as also the inner secondaries, the quills being otherwise 

 as in the adults ; lower back, rump, and upper tail-coverts 

 light brown, the long coverts mottled with whity-brown ; tail of 

 the latter colour, the centre feathers especially whitish, all 

 irregularly mottled with greyish-brown, which colour is most 

 developed on the edge of the feathers ; throat dark brown, with 

 white bases to the feathers, the sides of the face being almost 

 uniform dark hjrown ; rest of under surface of body mottled

 character, and the mottled jjlumage and whitish tail of the

 mens easy. Indeed it is only by gross carelessness that the 

 two species can be confounded, and yet we know that this is 

 often the case. 



Eange in the Britisli Islands. — Principally observed in England 

 as a migrant in autumn and winter, though it formerly bred on 

 many parts of the coast and in the Lake district, but even in 

 the south of Scotland it has become extinct as a breeding bird, 

 and places like Ailsa Craig, where there used to be an eyrie, no 

 longer know the species except as a chance visitor. In the 

 western isles of Scotland it still breeds, and also on the 

 northern coast. Mr. Ussher says that in its former breeding- 

 haunts in Donegal, Antrim, Dublin, Wicklow, Cork, Clare, and 

 Gal way it is extinct ; but a pair has bred recently on the coast 

 of Mayo, and another pair on the coast of Kerr)\ 



Ean^e outside the Britisli Islands, — The White-tailed Eagle is 

 found in most parts of Northern Europe, and breeds in Scan-
