The coastal and offshore waters of Southwest Greenland are internationally important winter quarters for seabirds. We crudely estimate a minimum of 3.5 million seabirds using the region in winter, mainly from Arctic Canada, Greenland and Svalbard, with smaller numbers also from Alaska, Iceland, mainland Norway and Russia. The most numerous species are Common Eider Somateria mollissima, King Eider S. spectabilis, Brünnich's Guillemot Uria lomvia and Little Auk Alle alle. The most immediate threat to the seabirds in Southwest Greenland is hunting, and current levels of usage of the Greenland breeding populations of Brünnich's Guillemot and Common Eider are considered unsustainable. Conservation measures are required for these populations.

The total breeding population of the Thick-billed Murre (Brünnich's Guillemot)Uria lomvia in west Greenland in 1951 was estimated to amount to two million pairs (Salomonsen, 1951), half of which inhabit the gigantic loomery at Kap Shackleton (Agparssuit) (Fig 1). Tuck (1960) considered this to be a conservative estimate, ‘and cannot concede that fewer than five million Thick-billed Murres inhabit the west coast of Greenland during the summer months’. The birds have long been considered an important food source by the inhabitants of the area. Rink (in Salomonsen, 1951, p 378) recorded a harvest of 70 000 birds as long ago as 1850; with the advent of modern shotguns and cheap ammunition the toll is now severe (Fig 2). As a result of shooting and disturbance population decreases have been recorded at various sites, but particularly those close to settlements (Table 1). In addition to the colonies listed in the table, a count was made in 1921 for the Sagdleq colony in the Umánaq district. An estimated 500 000 birds were recorded which, in 1949, had decreased to 250 000. In 1968 the Umánaq district legislated for total preservation of this colony for three years.

AbstractThe role of the gut microbiome is increasingly being recognized by health scientists and veterinarians, yet its role in wild animals remains understudied. Variations in the gut microbiome could be the result of differential diets among individuals, such as variation between sexes, across seasons, or across reproductive stages. We evaluated the hypothesis that diet alters the avian gut microbiome using stable isotope analysis (SIA) and 16S rRNA gene sequencing. We present the first description of the thick-billed murre (Uria lomvia) fecal microbiome. The murre microbiome was dominated by bacteria from the genus Catellicoccus, ubiquitous in the guts of many seabirds. Microbiome variation was explained by murre diet in terms of proportion of littoral carbon, trophic position, and sulfur isotopes, especially for the classes Actinobacteria, Bacilli, Bacteroidia, Clostridia, Alphaproteobacteria, and Gammaproteobacteria. We also observed differences in the abundance of bacterial genera such as Catellicoccus and Cetobacterium between sexes and reproductive stages. These results are in accordance with behavioural observations of changes in diet between sexes and across the reproductive season. We concluded that the observed variation in the gut microbiome may be caused by individual prey specialization and may also be reinforced by sexual and reproductive stage differences in diet.
