Seabirds

The Seabird Information Network focuses on the development of a data entry and analysis portal system that will allow for circumpolar seabird colony information to be contributed, mapped, and shared by scientists and monitoring programs around the Arctic. Data will be compiled to generate a circumpolar seabird colony assessment.

Sub Categories

Eiders

The common eider, Somateria mollissima, has a circumpolar distribution breeding mainly on small islands in Arctic and boreal marine areas in Alaska (Bering Sea region), Canada, Greenland, Iceland, western Europe, and the Barents Sea region. In Russia, there is a gap in distribution along the mainland coast from the Yugorski Peninsula (Kara Sea) to Chaunskaya Bay in east Siberia (Figure 5.1). Important wintering areas include the Gulf of Alaska/Bering Sea/Aleutian region, southeast Canada, southwest Greenland, Iceland, Western Europe, along the Russian coast of Barents Sea, and in the White Sea. Six or seven subspecies are recognized, of which four occur in North America (Arctic Biodiversity Trends 2010.)

Murres

The two species of murres (known as guillemots in Europe), the thick-billed murre, Uria lomvia, and common murre, Uria aalge, both have circumpolar distributions, breeding in Arctic, sub-Arctic, and temperate seas from California and northern Spain to northern Greenland, high Arctic Canada, Svalbard, and Novaya Zemlya. The thick-billed murre occurs mostly in Arctic waters, while the common murre, although overlapping extensively with the thick-billed murre, is more characteristic of sub-Arctic and temperate waters. They are among the most abundant seabirds in the Northern Hemisphere with both species exceeding 10 million adults. (Arctic Biodiversity Trends 2010.)

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.

LifeLinkedtoIce diets of thick billed murres

 

 

This chart shows the breakdown by species of identified fish in stomach samples of murres. Polar cod continue to dominate the diets of high Arctic murres, but capelin appear to have replaced polar cod in the low Arctic, where ice has retreated to the greatest extent. Capelin have also appeared in the mid Arctic, where the species was absent in 1985 samples but present in a third of the samples from 2007/08.

LifeLinkedtoIce Thick billed murre colony size

 

 

Based on analyses of data from areas around 46 murre colonies, grouped into regions. Colony sizes are historical maximum estimates of numbers of birds (representing carrying capacity) rather than current population sizes. This approach avoids the confounding factor of overharvest in some areas in recent decades. Sea ice conditions are based on satellite measurements, 1979 to 2004.

The depletion was probably mainly caused by overharvest (hunting and egg collection), while the recovery was the result of tightened legislation and cooperation with local hunters since 2001 (Gilliland et al. 2009, Merkel 2010).
