While humans may not have the hawk’s amazing eyesight, a new study suggests that both hawks and humans use similar visual techniques for search. To better understand the scanning techniques of a hawk, researchers mounted a camera on the head of a Northern Goshawk. Combined with footage of hunting raptors, gathered from the ground, authors found that hawks alter head movement patterns based on environmental information, with eye movement changing as a bird detects a potential target. This is similar to human visual search behavior.
