Commonly called the "Seagull", the Herring Gull is best known as a scavanger. It is most often seen in large, noisy flocks congregating where food is available, around fishing boats, picnic grounds and garbage dumps. Many people consider it a nuisance, but the Herring Gull performs a valuable service. It scavanges up great numbers of dead or injured animals and organic litter which could pose a health threat to humans. In the fields it devours large amounts of destructive pests such as grasshoppers, and mice. However, its natural diet includes aquatic life - fish, crustaceans and, sometimes, the eggs and young of other species.

The call of the gull is distinctive, a shrill, screatchy Eurl repeated incessantly.
