Polar Bear Tracker
Hudson Bay Polar Bears
Each autumn, a sampling of female polar bears are fitted with GPS collars in Western Hudson Bay (by the University of Alberta and Environment and Climate Change Canada) and Southern Hudson Bay (by York University and the Ontario Ministry of Natural Resources). The bears may or may not have cubs and vary in age, usually from 5 to 25. The age you see reflects their age at the time they were collared. These research programs have been active for several decades, providing some of the best long-term monitoring datasets for polar bears in the world.

Polar Bears & Changing Ice
The polar bears of Hudson Bay live in a seasonal ice area, where the ice melts completely in summer and freezes again in fall. Follow the bears on our tracker as they hunt seals when the bay is frozen or are forced ashore during the ice-free seasons.
