 to the northward of the Orange River. It is at once a

The Tawny Eagle is not uncommon in Damara Land 

 and Great Namaqua Land. It perches usually on the 

 topmost branches of lofty trees, often remaining station- 

 ary for hours together ; it builds on the top of high and 

 generally of inaccessible trees, and constructs a large 

 nest of dry sticks. It is very destructive to the young
