Seagulls in Umag, Croatia
Seagulls are awesome birds, but... If you are eating something outside or if there's a chance that you will eat something soon, they are there waiting for their fair share. And as soon as one seagull gets something, more will come after him. Sometimes, they even sort of attack people, who carry some food, i.e. a waiter who brings food to the table.
Therefor, don't forget the rule ... do not feed them ... there is plenty of food for them in the sea.
