Although many of us love to have birds around there are many who are not so fond of them. There are reasons for this. Living by the sea means living with gulls and gulls are big. They eat a lot and yep, they poop a lot too. When you see caps on posts like this you know the owner of the dock doesn't wish to have gulls hanging around messing up his or her dock. Of course gulls are not stupid. They sit on the dock itself quite fine.
This walkway is at a local beach and will be cleaned daily once the beach season begins but for now, it is one big buffet table for area gulls.
