As the silver gull is a big bird, it makes a lot of noise and a lot of mess! Apart from the disturbance there are concerns with regarding to disease and parasite transmission.
Around tourist areas and shopping areas, some silver gulls have become aggressive when ‘begging’ for food, as a result of people feeding them scraps (either intentionally or through leaving food behind).
Silver gulls can also be a serious safety concern around airports and have been involved in hundreds of “bird strikes” with aeroplanes.
When large numbers of silver gulls congregate around water bodies used for drinking water, the bacterial loading in the water can increase significantly through their droppings and regurgitated food.
