The great black-backed gull is largest species of gulls in the world. With its wing span of 170 centimeters and their enormous beak, they look very impressive. They also make a much lower and raspier sound than the other gulls. In 1993, they nested in the Netherlands for the first time. Since then, there have been a number of nesting pairs every year. Greater black-backed gulls eat fish, shellfish and other molluscs, worms and insects. They will also hunt other birds, such as the manx shearwater, little auks and puffins. Due to their size, they easily steal food from other birds.
