In any coastal city there are many Seagulls around. These seagulls at Hillaries Harbour in Australia where particularly pesty in that they actually tried to take the food off your plate. They sit on the tables and circle around your table waiting to strike at any moment. Some of the restaurants actually supply a bottle of water with which to spray them as a deterrent, this particular restaurant however did not offer that service. The staff also warn you to watch your food, and as soon as you have finished eating the staff will remove your plate. Here are a few photos of the gulls around our table.
