The Iceland Gull is a medium-sized species of migratory gull. They breed in the Arctic. Many bird winter around the Great Lakes and the northeastern United States.
Iceland Gulls feed on fish which are often taken from the surface of the water without landing. They also eat other marine animals as well as eggs from other birds and scraps found in dumps or sewage.
The Iceland Gull has an interesting taxonomical history. As of 2017 there are considered to be three subspecies of Iceland Gull. The species was "lumped" together with the formerly separate Thayer's Gull in 2017. The other subspecies are the nominate Iceland and Kumilien's.
