Terror birds, one of South America’s most feared prehistoric predators, didn’t use super sharp eyesight to catch prey, as do eagles, hawks, and other modern day raptors. Using sophisticated computed tomography X-ray scans and 3-D modelling software, researchers were able to show that these flightless giants actually hunted by listening to their quarry’s footsteps.
