There weren’t always as many Silver Gulls as there are now. Since the 1950s, society has become increasingly wasteful, with our rubbish tips now bulging at the seams. With this increased availability of food in the form of refuse, the population of Silver Gulls has exploded, and offshore islands which once supported small breeding colonies are now over-run. With so many gulls dominating these breeding islands, it is becoming increasingly difficult for terns and other seabirds to breed there.
