Together with rock, bucket and spades, seagulls are associated with the seaside.
But it seems those hungry birds eager for a bite of your lunch, could be swooping down from a city centre building soon.
The environmental charity Keep Britain Tidy, has warned that seagulls, which are a nuisance in costal towns, could become a major public health problem in Birmingham if people continue to drop food.
Seagulls can have a wing span of five feet and can swoop at speeds at 40 miles per hour. They are commonly seen scavenging on land fill sites and other places where food is plentiful, like abattoirs.
However in recent years the noisy birds have gradually moved inland and cities such as Manchester and Leeds now have seagull colonies.
Laura Butcher from Keep Britain Tidy said if we did not stop dropping litter, their numbers could increase.
She said: "Seagulls congregate in big numbers and can be quite terrifying. "They have been spotted in Manchester, Leeds and Sheffield and our trained surveyor was in Birmingham this week and he did see them.
"Seagulls will feed on any food and fast food is found on the majority of our streets. Fast food is not natural to them, they should be eating grains."
Ms Butcher's concerns are shared by the Royal Society for the Protection for Birds.
Andrew Waters, RSPB Central England public affairs officer, said that city centre buildings could also suffer damage as the seagulls nest in tall buildings.
In light of reports of seagull attacks, Mr Waters insisted such attacks are rare.
He said: "It is better to tackle the problem of the food source rather than culling them or putting up netting which is so much more expensive."
