A detailed hand-colored engraving shows a White-headed Eagle, now known as the Bald Eagle, in flight. The central eagle has dark brown plumage, a white head and tail, and yellow beak and talons. It is depicted diving towards a silvery-blue fish. In the background, there is a faint, large-scale outline drawing of an eagle's head and eye to indicate the actual scale of the bird. To the left, a smaller, less detailed bird of prey is shown in flight. The main eagle and the fish are realistically colored, while the secondary elements are rendered in lighter, monochrome tones.
original: "Aquila capite albo"
