Ammon News – Scientists studying polar bears were greeted with a most unexpected surprise during a recent tracking expedition in northeastern Manitoba.
A polar bear mother and her cub were walking near Churchill in mid-November when scientists saw her with a second cub, which they were able to verify was not her own. It marks just the 13th such case of cub adoption within the western Hudson Bay subpopulation.
“When we got confirmation that this was an adoption, I had a lot of mixed feelings, but mostly good,” Alysa McCall, director of conservation outreach and a staff scientist with Polar Bears International, said in a video provided to media.
“It’s just another reason why this species is so incredible, why they’re so fascinating and interesting, and it gives you a lot of hope when you realize that polar bears may be looking out for each other out there.”
Evan Richardson, a polar bear research scientist with Environment and Climate Change Canada, was in the field back in March. His team of researchers caught up with the mother coming out of the denning area in Wapusk National Park, south of Churchill.
During that sighting, the mother only had one cub with her, Richardson said on a separate video provided to media.
Fast forward to the fall and Richardson was taken aback seeing the family of two having become a family of three. Two of the bears had been previously tagged with GPS-tracking collars and the newly adopted cub didn’t have one.
“It’s not that frequent though because in our long-term study we have over 4,600 individual bears that we’ve known over the last 45 years, and literally hundreds and hundreds of litters [of cubs],” he said of the adoption.
