The black-headed gull is a common breeding bird in Iceland and is known for
the dark hood it displays during the breeding season. It inhabits both
coastal and inland areas, including lakes, rivers, and wetlands. The species
is highly social and often breeds in large colonies.
Its diet includes insects, fish, and carrion, and it frequently forages near
human settlements. The black-headed gull plays an important role in the
ecosystem. It is a familiar sight in many parts of Iceland.
