“…For example, Thick-billed Murre Uria lomvia populations are increasing in Canada (Gaston et al, 2012) but declining in Greenland (Merkel et al, 2014), while Lesser Black-backed Gulls are increasing in Greenland (Boertmann, 2008) and Ivory Gulls Pagophila eburnea have declined in both Canada and Greenland (Gilg et al, 2009). Black-legged Kittiwake Rissa tridactyla numbers have declined in Greenland (Labansen et al, 2010), Norway (Krasnov et al, 2007;Cury et al, 2011), and northwestern Russia (Krasnov et al, 2007), but in Arctic Canada they are apparently increasing (Mallory et al, 2009b). Northern Fulmar Fulmarus glacialis numbers appear to be in slow decline in Canada (Gaston et al, 2012), and perhaps across the North Atlantic (e.g., JNCC, 2013).…”

ABSTRACT. The entire world population of the Glaucous Gull Larus hyperboreus breeds in the circumpolar Arctic. Some local populations appear to be declining significantly. In this paper, we summarize the current state of knowledge on Glaucous Gull populations and trends. The total Arctic population is estimated at 138 600 to 218 600 breeding pairs (277 200 to 437 200 breeding individuals) distributed among at least 2768 colonies (many not documented). Population declines may be attributable to egg harvest, contaminants, or food shortages, but other factors operating outside the breeding season should not be excluded. We recommend collaborative conservation efforts that will include better population estimates in most countries, as well as standardized monitoring programs.Key words: Glaucous Gull; Larus hyperboreus; Arctic; population status; population trends; monitoring; conservation concerns RÉSUMÉ. Toute la population mondiale de goélands bourgmestres Larus hyperboreus se reproduit dans l'Arctique circumpolaire. Certaines populations locales semblent diminuer considérablement. Dans cette communication, nous résumons l'état actuel des connaissances sur les populations et les tendances concernant le goéland bourgmestre. La population arctique totale est estimé de 138 600 à 218 600 couples reproducteurs (de 277 200 à 437 200 individus reproducteurs) répartis dans au moins 2 768 colonies (dont grand nombre n'ont pas été consignées). Les déclins de population peuvent être attribuables à la récolte des oeufs, aux contaminants ou aux pénuries de nourriture, bien qu'il ne faille pas exclure d'autres facteurs ne se rapportant pas à la saison de reproduction. Nous recommandons des efforts de conservation communs qui comprendront de meilleures estimations de population dans la plupart des pays de même que des programmes de surveillance normalisés.

“…Methods used in the Canadian Arctic to census seabird colonies and monitor population changes have been summarized for thick-billed murres by Gaston (2002), for northern fulmars by Gaston et al (2006) and for black-legged kittiwakes by Mallory et al (2009). Briefly, large colonies are normally censused by counting all birds present on the entire colony on high-resolution photographs.…”

“…Treating the two breeding aggregations on Akpatok Island (20 km apart) as separate colonies, but lumping those on Princess Charlotte Monument with those on adjacent Coburg Island (6 km apart) and those on either side of Digges Sound (10 km apart) as a single colony, there are 10 thick-billed murre colonies and 11 northern fulmar colonies (Gaston 2002;Gaston et al 2006). There are nine black-legged kittiwake colonies supporting [1,000 breeding pairs and a further 10 smaller colonies, not all of which are occupied every year (Mallory et al 2009;MLM unpubl.). Four thick-billed murre colonies on eastern Baffin Island or in the high Arctic are co-located with black-legged kittiwakes and two are co-located with both black-legged kittiwakes and northern fulmars (Fig.…”

Populations and trends of Canadian Arctic seabirds

Canada's eastern Arctic (Nunavut and Arctic Quebec-Nunavik, N of 60°) supports large numbers of seabirds in summer. Seabird breeding habitat in this region includes steep, rocky coasts and low-lying coasts backed by lowland sedge-meadow tundra. The former areas support colonial cliff-and scree-nesting seabirds, such as murres and fulmars; the latter inland or coastal seabirds, such as terns, gulls and jaegers. The region supports some 4 million breeding seabirds, of which the most numerous are thick-billed murres (Uria lomvia; 75%), black guillemots (Cepphus grylle; 9%), northern fulmars (Fulmarus glacialis; 8%) and black-legged kittiwakes (Rissa tridactyla; 6%). The majority of Arctic seabirds breed in a small number of very large colonies ([10,000 birds), but there are also substantial numbers of non-colonial or small-colony breeding populations that are scattered more widely (e.g. terns, guillemots). Population trends among Canadian Arctic seabirds over the past few decades have been variable, with no strongly negative trends except for the rare ivory gull (Pagophila eburnea): this contrasts with nearby Greenland, where several species have shown steep declines. Although current seabird trends raise only small cause for concern, climate amelioration may enable increased development activities in the north, potentially posing threats to some seabirds on their breeding grounds.

ABSTRACT. Prince Leopold Island is the most important marine bird colony in the Canadian High Arctic. An Environment Canada research camp on the island was occupied for varying periods (mean 37 days) during 18 summers from 1975 to 2012. Research concentrated on the biology of the marine bird colonies, but incidental notes were kept on other sightings of birds and mammals. Forty-seven species of birds, of which 12 bred, six species of terrestrial mammals, four seals, and three whales were recorded on or from the island. Sightings of Ivory Gull and Brant decreased over the period considered, while sightings of Peregrine Falcons and breeding records of Baird's Sandpipers increased. Collared lemmings invaded the island in 2009, and extensive evidence of their presence was found by 2012. Arctic fox presence has become more frequent. Some or all of these changes may be related to recent climate warming and increased precipitation in the area. Eleven species of small passerines that normally do not breed north of the tree line were recorded, most often in June, suggesting that their appearance was due to migration overshoot. The regular appearance of southern passerines suggests that colonization of the Arctic Archipelago by sub-Arctic species may occur rapidly if climate and vegetation become more suitable. La présence du renard arctique s'est également amplifiée. Une partie ou la totalité de ces changements pourrait être attribuable au réchauffement planétaire et aux précipitations accrues dans la région. Onze espèces de petits passereaux qui ne se reproduisent normalement pas au nord de la limite forestière ont été répertoriées, la plupart du temps en juin, ce qui suggère que leur présence était attribuable au dépassement de la migration. La présence régulière des passereaux du sud laisse entrevoir que la colonisation de l'archipel Arctique par les espèces subarctiques pourrait se produire rapidement si le climat et la végétation devenaient plus appropriés.
