The Black-Headed Gull is a medium-sized seabird found across Europe, Asia and North Africa. In summer, their heads are a rich chocolate brown rather than black. These gregarious gulls breed in large, noisy colonies near water like lakes and marshes. They mainly eat insects, worms, and scraps but will take almost anything edible. In winter, their heads are white like their bodies. Though numerous, their numbers have declined due to habitat loss, pollution and human disturbance near nesting areas. These tough, adaptable gulls have learnt to thrive in towns and cities, scavenging food from bins and parks.
