Polar bear dens on the Seal and Caribou Rivers, Manitoba
During aerial surveys we opportunistically located clusters of polar bear (Ursus maritimus Phipps, 1774) earth dens on and near the Seal and Caribou Rivers in Northern Manitoba in 2011, 2022, and 2023. Polar bear denning has not been documented in the published literature there before, but there is...
