When picking what to eat, seagulls look to humans for inspiration – and strongly prefer items that resemble what people are eating nearby
– or kleptoparasites, to use the scientific term. “Many people still think that gulls are not very smart, even though kleptoparasitism to us suggested a higher level of cognition, so we wanted to explore this further,” says Franziska Feist at the University of Sussex, UK.
Feist and her colleagues studied gulls on the Brighton beachfront for a few months in 2021 and 2022. They presented blue and green packets of potato crisps to groups of gulls. An experimenter sat on the ground about 5 metres away and either idly watched the gulls or pulled out a green or blue packet from their bag and ate from it.The researchers found that 48 per cent of the birds approached the packets when the experimenter was eating, compared with 19 per cent when they weren’t.
