Polar bear depredation of a thick-billed murre fledgling in open water at Prince Leopold Island, Nunavut

Sea-ice distribution and duration are declining across the circumpolar range of polar bear (Ursus maritimus), resulting in a reduced access to ice-obligate seals, its primary prey. Consequently, bears may have increased reliance on alternative food sources future. Foraging land is well documented but foraging open water less understood. We report successful depredation thick-billed murre (Uria lomvia) near Prince Leopold Island, Nunavut, discuss implications for understanding behavioural plasticity their opportunistic patterns. _______________________________ View supplementary video
