Bears in captivity provide researchers with more accessibility and data than those in the wild.
to develop new technology for tracking polar bears in the wild. Currently, satellite collars that go around the neck of the polar bear are the most commonly used tracking technology. These devices allow researchers to collect data on wild polar bears’ movements and activities, such as how long they swim. However, the collars can only be placed on adult females, excluding males and juveniles from the data pool.
To solve these issues, PBI and 3M developed several “Burr on Fur” satellite trackers that could attach to the fur of the polar bear, like how a plant burr clings onto clothes or animal coats. This way the tracker doesn’t harm the polar bear and can also stick onto polar bears of any size. So far the researchers have deployed 17 tags on wild bears in the Hudson Bay region in Canada and have tested them with polar bears from nine different zoos.
