Moving problem bears

tranquilized cubs awaiting transfer to helicopter

A decade ago, polar bears that wandered into Churchill would be shot.  A horrible outcome for a hungry bear seeking food after months of fasting on the tundra during the summer when there is no pack ice for hunting seals, the polar bears’ food.

To make things worse, Churchill had a town dump where bears congregated to search for food.  When the town finally decided to close the dump and bury or haul out the trash by rail, it took several generations of bears before the memory of food at the dump faded.  Meanwhile, over the last 10 years, the bear population around Churchill, now 852 bears, declined from 1000 bears, a disastrous drop in population brought on by starvation and shooting wayward bears.  Because of global warming, polar bears now fast for 6 weeks longer than they used to, leaving them weakened and very hungry by late fall.  They live off the fat they accumulate during the winter hunting seals.

Now, bears that venture into town are captured in a trap and taken to the “bear jail” just outside of town.  There they are not fed (they aren’t eating anyway), but are given a little water, and “trained” to think they would be better off on the tundra instead of in town.  Other bears, particularly repeat offenders, are tranquilized and carried off by helicopter 40 or 50 miles away, but still in their territory.

We got lucky and were able to watch one of these transfers of a mother polar bear and her 2 cubs.  All were tranquilized with a dart that injects a sedative lasting one hour, so everyone has to work fast.  The mother bear was wrapped up carefully in a net that would be securely fastened to a tether hanging down from the helicopter.  The babies (quite large) were carried by attendants like giant pandas and placed in the seats inside the helicopter.  Cubs are always moved with their mothers, never separated.

Once the cubs were inside, the pilot lifted the helicopter about 10 feet off the ground so the mother could be attached.  Then, off they went with cubs inside and mother swinging gently below.  Despite the tranquilizer, this is a traumatic experience for the bears, so they cover their eyes to keep them from being even more frightened.

A second helicopter accompanies the one with the bears to make sure all goes well at the drop off site.  The rangers land and stay with the bears until they wake up and run off, protecting them from any predators and making sure they have no ill effects from the tranquilizer.

The transfer costs $10,000 per event, paid for by a combination of private and public funds.  Both Natural Habitat, our tour company, and their partner, the World Wildlife Federation, provide funds for these transfers, along with the Canadian government.
