text: The gulls are found all year round in the streets and gardens of Britain, due to the presence of street lighting (which allows the gulls to forage at night), discarded food in streets, food waste contained in easy-to-tear plastic bin bags, food intentionally left out for other birds (or the gulls themselves), the relative lack of predators, and readily available, convenient, warm and undisturbed rooftop nesting space in towns and cities.
