Framed painting of an eagle with light coloured head, chest, and belly, with wings of gradient shades of brown, standing on a rock with full leaves behind it. Pencilled notes and measurements in lower left corner: "N. Bonelli (33)" (remainder of inscription too faint to read).

Mounted painting of a brown and white eagle actively crouched on a rocky cliff, overlooking water and a distant background with very small pagoda, copse of palms, and ship in water. Inscriptions below the painting read, "Bonelli's eagle (intermediate plumage) Hieraaetus fasciatus" at bottom center, and then slightly to right of that, "? Hieraaetus fasciatus fasciatus Bonelli's eagle (intermediate plumage) (191 – K.S.)."
