Seagulls have earned a reputation as the primary thieves of the seaside. Research from the University of Exeter suggests these birds are highly observant, often timing their food raids by watching human behavior. Herring gulls frequently target food items when they sense a person is distracted or unaware of their presence.
Animal behavior researcher Laura Kelley found a practical way to discourage these birds. By placing googly eyes on food packaging, people can mimic a predatory gaze. Gulls often show caution when they believe they are being watched, as a direct stare typically signals an impending attack from a competitor or predator.
Beyond basic theft, these birds display high levels of social intelligence. Studies show that gulls observe human food choices and mimic them, choosing items based on color-matching cues. This intelligence is a double-edged sword, as it allows them to adapt quickly to urban environments where they scavenge human leftovers.
Despite their frequent presence in cities, global herring gull populations face significant decline due to habitat loss and overfishing. Experts suggest that birds seen in urban areas are often forced to adapt to human food when their natural prey is unavailable. Understanding this behavior allows for better coexistence, such as sitting with your back to a wall or keeping food covered during outings.
