48 NORTH AMERICAN OOLOGY. PART I. 



Eagle, quitting the breeding station when the season is ended, leave their young to 

 forage over the district in which they have been raised. In confinement, the White- 

 tailed Eagle sometimes becomes sociable One kept by Mr. Hoy laid three eggs 



in the same season ; and a female in the possession of Mr. Selby laid an egg after 



having been kept in confinement twenty years The White-tailed Eagle breeds 



in the Hebrides, in Orkney and Shetland. Mr. Dunn, in his useful guide to these 

 latter islands, names the particular localities in which they may be found, but states 

 that they are much more numerous in winter than in summer. This accords with 

 the opinion of M. Temminck and others, that this species returns to the southward 



from high northern latitudes as the season advances This Eagle frequents 



Denmark, Sweden, the west coast of Norway, and from thence as far north as Ice- 

 land and Greenland, but is not found in North America. Mr. Temminck believes 

 that this Eagle follows the flocks of Geese that annually resort to the Arctic regions 

 in summer to rear their young. It is found in Siberia, at Lake Baikal, and inhabits 

 Russia, from whence to the southward it is spread over the European continent 

 generally."

The White-headed, or, as it is also incorrectly called, the Bald Eagle, is widely 

 diff"used throughout the North American continent, from at least latitude 66° 34' 

 north, to the Gulf of Mexico and Central America. It is also of accidental occur- 

 rence in Europe. Temminck records two specimens as having been obtained in 

 Central Europe, one in Zurich in Switzerland, the other in the kingdom of Wurtem- 

 berg. He also speaks of this species as frequenting the North of Europe, and in his 

 latest edition, on the authority of Mr. Boie, states that they breed on some of the 

 Norwegian islands. Their accidental occurrence in Central Europe may perhaps be 

 readily accounted for by the escape of birds who had been in confinement. Their 

 frequenting Northern Europe, excepting as chance visitants, needs confirmation.
