Great Black-backed Gulls are the largest gull in the world and are found in north-eastern North America and all along the northern part of Europe. They have a well-deserved reputation for bullying and stealing so they can easily rule the beach. The Least Terns are harassing this gull for a very good reason. Their nesting area is nearby and Great Black-backed Gulls will readily snatch eggs and chicks. This one was busy with a fish carcass but the terns weren’t taking chances.
