Starlings were slower to (a) approach and (b) feed from a food source if a nearby (human) predator's eyes were visible rather than covered: mean difference in latency (eyes showing minus eyes covered) was positive for approach and feeding in both sexes. Starlings also (c) fed at a slower rate and (d) ate fewer mealworms (mw) in total from a food source if a nearby (human) predator's eyes were visible rather than covered: mean difference in latency (eyes showing minus eyes covered) was negative in both sexes. Values represent mean difference ±1 s.e.
