Is probably the young of the golden eagle, though formerly considered a 
distinct species. When young, the body is of a lighter color than that bird, 
but deepens into a blackish brown as the eagle advances in age. 
The tail feathers of this bird are highly valued by the various tribes of 
American Indians, for ornamenting their calumets or pipes of peace. The 
ring-tailed eagle is characterized as a generous spirited and docile bird. Its 
solitary habits, the vast inaccessible cliffs to which it usually retires, united 
with the scarcity of the species in those regions inhabited by man, all com- 
bine to render a particular knowledge of its uabits very difficult to be ck tained. 

THE ‘OSPREY EAGLE 
Tuts bird and the sea eagle have often been confounded with eacn other. 
They are, however, very different. The osprey, both male and female, is 
much smaller than the sea eagle; the tarsi of the osprey are scaly and 
naked, while those of the sea eagle are feathered part of the way; the 
osprey may be trained to catch fish for its keeper, but the sea eagle will not 
serve a master.
