We gathered local ecological knowledge (LEK) on the ivory gull (Pagophila eburnea) from residents of three High Arctic communities in eastern Canada. This gull has always been uncommon, but Inuit had suggested that numbers of gulls were declining. LEK from Grise Fiord and Resolute Bay was clear and consistent, indicating that far fewer gulls are currently observed near the community compared to 25 years ago. The LEK from Arctic Bay was less consistent, although in general, community members thought that the species was less commonly observed. Observations from nonsystematic surveys by local wildlife officers corroborated the LEK data, and an aerial survey of the known colony locations on the Brodeur Peninsula (near Arctic Bay) found only one gull. Collectively, this information suggests that ivory gull populations are declining across the species' Canadian range. Systematic surveys will be needed to confirm these perceived declines.

The Canadian Arctic provides important habitat for millions of marine birds. Some key habitat sites for these have already been protected, but many others lack official protected status and remain vulnerable to various anthropogenic threats. The authors worked with the community of Qikiqtarjuaq, Nunavut, to create two new National Wildlife Areas that protect the colonies, and the nearby marine area, of approximately 500,000 birds during the breeding season. The process has taken two decades to complete, in part due to misunderstanding and mistrust of government on the part of aboriginal residents. In this paper the path that led to the creation of these sites is traced. This has included the approach adopted to collaborating with the local community, incorporating aboriginal (local) ecological knowledge, conducting scientific surveys while building local capacity for further scientific investigation, and finding a solution that addressed the disparate interests of the various stakeholders in this process.

Evidence from colony surveys and local Inuit knowledge strongly suggest that the Canadian population of ivory gulls (Pagophila eburnea) has declined dramatically. The observations of ivory gulls at sea presented here are consistent with this. Ivory gulls were observed during two cruises on the Russian icebreaker Kapitan Khlebnikov in the eastern Canadian high Arctic in August 1993 and 2002. Ivory gulls were seen 3.5 times more often in 1993 (n = 176) than in 2002 (n = 149), and, corrected for observation effort, four times more ivory gulls were seen in 1993 than in 2002. Ivory gulls are scavengers: they were never observed feeding on fish behind the vessel while ice-breaking, although black-legged kittiwakes (Rissa tridactyla) often were seen feeding in this way. Ivory gulls were observed scavenging around polar-bear (Ursus maritimus) kills in 1993 but not in 2002. By far the largest number of ivory gulls was seen near Grise Fiord in 1993. There, opportunities for them to scavenge were likely good at the community landfill as well as at Inuit and polar-bear kills due to complete ice coverage of the surrounding marine area. No ivory gulls were seen there in 2002. Observations of four individuals in 1993 and five individuals in 2002 near the southern end of Eureka Sound and in Norwegian Bay, 150 km from the nearest known breeding colonies, suggest that as yet undiscovered colonies might exist in this area. With three lines of evidence (colony surveys, local Inuit knowledge, at-sea surveys) now indicating population decline, urgent reassessment of the status of ivory gulls in Canada needs to take place.

The accepted breeding distribution of Canada Geese from the Atlantic Population (Branta canadensis interior) in the eastern Canadian Arctic is currently confined to northern Québec and the south coast of Baffin Island. Here we provide evidence based on observations from scientific studies, Inuit hunters, and territorial Wildlife Officers that B. c. interior now breeds in growing numbers 500 km farther north on northeastern Baffin Island than previously reported. Cackling Geese (B. hutchinsii), which breed more widely across eastern Arctic Canada, to about 72°N, may also be increasing there. Moreover, individuals of both species are seen occasionally as far north as Ellesmere Island in small flocks and within migrating or moulting flocks of Snow Geese (Chen caerulescens) or Brant (B. bernicla hrota), though none of these far northern stragglers are known to have bred. Whether these observations reflect a recent range expansion or improved distributional knowledge from more intensive recent survey efforts remains unknown.
