Genus Aquila, Brisson. 



*201. A. chrysaetos canadensis (Linn.) Ridgw. Golden Eagle. Chiefly 

 winter visitant, but a few stiU breeding in rocky, unfrequented districts (see 

 Nelson, p. 120). 



Genus Hali^etus, Savigny. 



*202. H. leiicocephalus (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 a-pparent 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 chrysaetiis 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 .
