Ivory Gull

The Ivory Gull Pagophila eburnea is a high Arctic seabird which is often associated with sea ice throughout the year. In spite of an early discovery by Jonas Poole in 1609, it still remains one of the most poorly known seabird species in the world. The Ivory Gull breeds at high latitudes in the Atlantic sector of the Arctic. Small, scattered colonies occur in Arctic Canada, Greenland, Svalbard (Norway), and the northern islands of Russia in the Barents and Kara Seas. The wintering distribution of the Ivory Gull is poorly known, although it generally winters along the southern edge of Arctic pack ice in the waters of the North Atlantic Ocean (Davis Strait and Labrador, Greenland and Barents Seas), and the North Pacific Ocean (Bering Sea, Sea of Okhotsk, and perhaps the Beaufort and Chukchi Seas).

LifeLinkedtoIce Nesting ivory gulls

The bars show survey results at the world’s largest ivory gull nesting colony on Domashny Island. Numbers of nesting ivory gulls fluctuate from year to year depending on environmental conditions in the pre-breeding season (mid-May). In the northeastern Kara Sea, where wildlife is limited by the harsh ice conditions, polynyas are important for foraging [255]. More gulls are able to build up enough fat resources for egg-laying when there is more open water in a large nearby polynya prior to nesting. If the area of the polynya remains below a threshold of about 10,000 square kilometers (dashed line) by mid-May, dramatically fewer gulls nest at the colony, as occurred in 1996, 2009 and 2011.
