European herring gull
Their loud, laughing call is well known in the Northern Hemisphere, and is often seen as a symbol of the seaside in countries such as the United Kingdom. The European herring gull also has a yelping alarm call and a low, barking anxiety call. The most distinct and best known call produced by European herring gulls – which is shared with their American relative – is the raucous territorial 'long call', used to signal boundaries to other birds; it is performed by the gull initially with its head bowed, then raised as the call continues.
