From the Spotted Eagles this species is readily distinguishable in having a vertical and not a round nostril.

In habits this is a heavy bird, frequenting the Steppes and open country and feeding on small mammals, reptiles, and carrion, sometimes capturing small birds. Its nest, which is invariably placed on the ground, frequently on a low mound, is constructed of twigs and boughs lined with grass, plant-stems, or wool, and the eggs 2, rarely 3 in number, are usually deposited in May, and are white with violet grey shell-markings and deep red surface-spots and blotches, and are as a rule not richly marked though sometimes they are as well and boldly marked as those of A. pomarina. In size they average by 2.35.
