Many hybrid bears appear to retain the all-brown fur coat of their grizzly-bear parent, while others have lighter brown fur. As these icy regions shrink, polar bears must travel further to find food. Observations made in captivity and a study conducted in the wild also suggest that the hybrids are fertile and have themselves produced young. As the sea ice continues to shrink, tundra regions are growing larger, allowing grizzly bears to move further north in search of food.

Hybrid bears are mostly found around the Northern Territories in Canada. All have been males, most of which are thought to have traveled from the mainland over the ice to the islands during the spring mating season. This appears to reflect a process in which a population of polar bears was left behind as the species retreated northwards at the end of the last ice age, with male brown bears subsequently introducing genes from the adjacent mainland, but female brown bears being generally unable or unwilling to swim across several kilometres of open ocean to reach the islands (thus the lack of exchange of mitochondrial DNA).
