347a. ROUGH-LEGGED HAWK. _Archibuteo lagopus sancti-johannis._

Range.--Northern North America, breeding chiefly north of our borders
and wintering south to the middle portions of the United States.

The Rough-legs are large, heavily built birds of prey, specially
characterized by the completely feathered legs. The present species is
22 inches long, and in the normal plumage has a whitish head, neck,
breast and tail, the former being streaked and the latter barred with
blackish; the remainder of the upper and underparts are blackish brown.
Their nests are usually placed in trees, and less often on the ground
than those of the next species. These Rough-legs are very irregularly
distributed, and are nowhere as common as the next. While the greater
number nest north of the United States, it is very probable that a great
many nest on the higher ranges within our borders. The species is often
taken in summer, even in Massachusetts. They lay three eggs of a bluish
white color, boldly splashed with dark brown; size 2.25 x 1.75.

348. FERRUGINOUS ROUGH-LEG. _Archibuteo ferrugineus._

Range.--North America, west of the Mississippi, breeding from the
latitude of Colorado north to the Saskatchewan region.

This species nests very abundantly along our northern states,
particularly in Dakota. It is a larger bird than the preceding and can
easily be told by its reddish coloration, particularly on the shoulders
and tibia. While in some localities they nest only in trees, the greater
number appear to build their nests on the ground or rocky ledges, making
a large heap of sticks, weeds and grass. Their three or four eggs are
white, beautifully spotted and blotched, in endless variety, with
various shades of brown. Size 2.60 x 2.00. Data.--Stark Co., N. D.,
April 29, 1900. Nest built of coarse sticks on a clay butte.

349. GOLDEN EAGLE. _Aquila chrysaetos._

Range.--North America, west of the Mississippi; most abundant in the
Rockies and along the Pacific coast ranges.

This magnificent bird, which is even more powerful than the Bald Eagle,
measures about 34 inches long, and spreads about 7 feet. Its plumage is
a rich brownish black, very old birds being golden brown on the nape.
They can be distinguished in all plumages from the Bald Eagle by the
