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 chrysætos._ 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 completely feathered tarsus. They build their nests in the tops of the tallest trees in the wild, mountainous country of the west, and more rarely upon ledges of the cliffs. The nests are made of large sticks, lined with smaller ones and leaves and weeds. Their eggs are the most handsome of the Raptores, being white in color, and blotched, splashed, spotted and specked with light brown and clouded with gray or lilac, of course varying endlessly in pattern and intensity. Size 2.90 x 2.50. Data.--Monterey Co., Cal., May 3, 1888. Three eggs. Nest of sticks, lined with pine needles, in a pine tree, 50 feet up.
