This noble species rarely leaves the mountainous districts of Scotland, and very few in- 

 stances of its capture in the Lowlands, or the borders of England, are upon record. 

 Bewick, however, mentions a very large one killed near Warkworth, which measured 

 eleven feet in extent of wing. The Ring-tailed Eagle of authors is now perfectly ascer- 

 tained to be the young or immature bird of this species.
