which are not addicted to astronomical investigation, have eyes organized

“On the ground, the Golden Hagle, like all others, is extremely awk- 
ward; for, owing to its large wings, its great weight, and the form of its 
toes, which are encumbered with very large curved and pointed claws, it 
can only walk in a very deliberate manner, or move from place to place 
by repeated leaps, in performing which it calls in the aid of its wings. Its 
feet in fact are not adapted for walking; they are most powerful organs of 
prehension, capable of inflicting mortal injury on any animal not exceed- 
ing a sheep in size. It is with them that it deprives its prey of life, and 
carries it off to its nest or to some convenient place of retreat. With its 
curved bill it tears off the feathers and hair; separates morsels of the flesh, 
and even crunches the bones of small animals.” 
The young differ from the old in plumage, the base of the tail being 
white. 
There is no specimen in the Museum of the Cleveland Academy of Nat- 
ural Sciences, but Dr. Kirtland possesses a skin. 
Genus Hatiatus—Savigny—FisHeR HAGLES. 
Size large; tarsi short, naked, or feathered for a short distance below 
the joint of the tibia and tarsi, and with the toes covered with scales; bill 
large, strong, compressed; margin of upper mandible slightly festooned ; 
wings rather long, pointed; tail moderate; toes rather long; claws very 
strong, curved, sharp. Of this genus there are four species indigenous to 
North America, viz: The Northern Sea Hagle, H. pelagicus ; the Wash- 
ington Hagle, H. Washingtonii; the Grey or European Sea Eagle, H. Albi- 
cilla(?); and the Bald or White-headed Hagle, HZ. lewcocephalus. All pre- 
fer to feed on fish, and frequent the shores of the ocean and lakes, and the 
banks of the larger rivers, for that purpose. They chase and destroy 
quadrupeds and birds, and the last-named species will kill and devour 
young pigs and lambs. The H. pelagicus is the largest Eagle known, and 
frequents the shores of the Pacific, from California to the Arctic Circle. 
H. Albicilla inhabits Greenland, but Cassin doubts if it is identical with the 
European bird of that name.
