Staring at seagulls can stop them stealing food, research shows 研究顯示，盯著海鷗看能阻止牠們偷走食物
Britain’s seaside towns are at war with their seagulls, urging visitors not to feed the birds in an effort to stop them snatching titbits like potato chips from tourists’ hands.
Warning signs deck promenade railings from Scarborough to Broadstairs and beyond but now research from the University of Exeter has suggested an easy way for holidaymakers to deter the gulls - just stare at them.
The research showed that with a human staring at them, herring gulls took 21 seconds longer to approach a bag of chips.
"Gulls are often seen as aggressive and willing to take food from humans, so it was interesting to find that most wouldn’t even come near during our tests," said lead author Madeleine Goumas. （Reuters）
