200. A. ferrugineus (Licht.) Gray. Ferruginous Rough-legged Hawk. 
Recently added to the fauna of the state, by Dr. Coues, who observed specimens 
near Rock Island, in October, 1876. (See Bull. Nutt. Orn. Club, II., p. 26.) 
Genus Aquila, Brisson. 
*201. A. chrysaetos canadensis (Linn.) Ridgw. Golden Eagle. Chiefly 
winter visitant, but a few still breeding in rocky, unfrequented districts (see 
Nelson, p. 120). 
Genus Haliasetus, Savigny. 
*202. H. leucocephalus (Linn.) Savig. Bald Eagle. Resident, but most 
abundant in winter. The young, which in their second year exceed the adults 
in spread of wing and tail, as well as in apparent bulk, while their plumage is 
exceedingly different, are commonly called “Gray Eagles.” Younger indi- 
viduals, or those in the first plumage, are distinguished as “ Black Eagles,” a 
name also applied to the Golden Eagle ( Aquila chrysaetus canadensis). Many 
persons, even experienced hunters, are unaware of the identity of these black 
and gray Eagles with those having the head and tail white. The “ Washington 
Eagle,” or “ Bird of Washington,” of Audubon, was founded on a large-sized 
immature female of this common species.
