Polar bear mother adopts cub in rarely documented case
A rare case of a polar bear mother adopting a cub not biologically her own has been documented by researchers in Churchill, Manitoba. The mother bear, part of the 13th known case among 4,600 studied bears, was spotted with both her biological cub and the adopted one during the annual polar bear migration. This unique behavior, though rare, showcases the bond and care within the polar bear community, offering hope for the species facing challenges from climate change. The cubs are expected to stay with their mother for about two-and-a-half years, learning essential survival skills before venturing out on their own.
