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,' said lead author Emma Inzani.
Human-associated foods are often both reliably present and easy to obtain - but when fish is available they clearly prefer it.
Previous research has shown that parent gulls often switch to finding more seafood once their chicks hatch, possibly due to seafood providing more of the nutrients chicks need to grow.
