Scientists discover why gulls always prey on people's food
Scientists discover why gulls always prey on people's food
Anyone who has braved a stroll along England's coastline will be aware of seagulls' tyrannical regime. They prey on people eating chips, they swoop down on unsuspecting holidaymakers licking an ice cream, and they can be quite aggressive indeed. And now, terrifying research has revealed that they are more calculating than you may have previously thought. A University of Sussex study on herring gulls at Brighton beach found that the birds choose what to eat by watching what humans are enjoying. Scientists taped green (salt and vinegar) and blue (cheese and onion) packets of Walkers crisps to tiles and placed them a few metres from gulls on Brighton beach and filmed the birds’ behaviour from a distance. In some cases, the researchers ate from one of the bags of crisps. When the scientists didn't eat, less than a fifth of gulls approached the crisp packets placed nearby. But when the researchers were snacking on crisps, 48 per cent of the birds came to check out the packets. Nearly 40 per cent of such approaches ended with gulls pecking at the crisp packets, and of these, 95 per cent were directed at the same colour packet as the scientist was eating from.

Knowing this may have implications for how we reduce negative interactions between humans and gulls, as we seem to be inadvertently teaching gulls to exploit new food items.” Meanwhile, past alarming research revealed that gulls prefer food that has been touched by people.
