Herring gulls notice where approaching humans are looking, and flee sooner when they’re being watched, a new study shows.
Researchers approached gulls while either looking at the ground or directly at the birds.
Gulls were slower to move away when not being watched – allowing a human to get two metres closer on average.
Newly fledged gulls were just as likely to react to human gaze direction as older birds, suggesting they are born with this tendency or quickly learn it. MORE
