omg u gotta try this!! so apparently shouting at seagulls is actually super effective in keeping them away 
i mean who knew?! i've been yelling at those pesky birds for years and now i know its actually doing something
anyway, researchers found that shouting is way more effective than talking or singing at deterring gulls from stealing your snacks 
the secret to success is not the tone but the volume
so next time u see a seagull swooping in go ahead and give it a good loud yell
dont worry about being rude its science lol
