- The Iceland Gull is divided into two subspecies. The western form known as "Kumlien's Gull," breeds in Canada and shows variable amounts of dark in the wingtips. The form that breeds in Greenland and winters from there to Europe, has very little or no dark in its wingtips.
- The Iceland Gull and the Thayer's Gull show many similarities and may be the same species. A range of darkness in the wingtips can be seen from fully dark ones in the western Arctic to fully white in eastern Canada, with lots of variation in between.
Breeds in coastal colonies on rocky precipices of steep cliffs from low to high Arctic, normally facing fjords or sounds, though occasionally up to several kilometers inland. Winters along shores of salt water and less often freshwater lakes and rivers.
Fish, carrion, offal in harbors, marine invertebrates, occasionally eggs and young of other birds; some terrestrial plants, algae, and berries in late summer.
