Seagulls in the city would rather eat seafood than ice cream.
New research has found that seagull chicks who have been raised on an 'urban' diet still opt for fish over human snacks when given the choice.
A team at the University of Exeter conducted a study on herring gull chicks that had been rescued after falling off roofs in Cornwall.
As they were raised in captivity, they were given either a 'marine diet' made up of fish and mussels or an 'urban' diet consisting of bread and cat food.
The gull chicks were sometimes provided with a choice of all four food items in different bowls and opted for the fish every time.
Emma Inzani, lead author of the study, said: "Our results suggest that, even when reared on an 'urban' diet of foods found only around people, these chicks might be unlikely to seek out urban foods as adults.
"Human-associated foods are often both reliably present and easy to obtain - but when fish is available they clearly prefer it."
