The Ivory Gull (Pagophila eburnea) has a circumpolar breeding distribution and spends the entire year at high latitudes in the Arctic and North Atlantic oceans. Due to its remote breeding locations and nomadic wintering habits, little detailed information on the ecology of this species exists, and no estimates of survival rate are available. Recent surveys have shown a dramatic decline, with an estimated 250-350 pairs now breeding in Canada. Across its range, the Ivory Gull was traditionally harvested by northern communities, and, although now protected, it is still shot in some regions. Ivory Gulls were banded in the Canadian Arctic (N = 1,526) in the 1970s and early 1980s. Most recoveries (N = 17) came from birds shot in northwest Greenland, while five birds were shot in Canada. As yet, no birds banded at more southerly locations have been recovered. Annual adult survival rate of 0.86 ± 0.04 and reporting rate of 0.03 ± 0.009 were calculated for birds banded at Grise Fjord and Seymour Island. The higher recovery rates of Ivory Gulls banded in northern areas suggests that hunting could have an impact on their already small population. Education programs to prevent further hunting of the species are recommended.
