The bird featured on the Mexican coat of arms is the golden eagle. This bird is known in Spanish as águila real (literally, "royal eagle"). In 1960, the Mexican ornithologist Rafael Martín del Campo identified the eagle in the pre-Hispanic codex as the northern caracara or "quebrantahuesos", a species common in Mexico (although the name "eagle" is taxonomically incorrect, as the caracara is in the falcon family). Even so, the golden eagle is considered the Mexican eagle for official purposes, and for the same reason is considered the official bird of Mexico.
