Farther north, on Canadas Melville Island, a research team sighted grizzlies in 2003 and 2004, even going so far as to photograph one fleeing from a helicopter near ground level. Although polar bears can adapt their diet to include sea bird eggs and caribou when on land, a 2015 study published in the journal Frontiers in Ecology and the Environment found that the calories they gain from these sources do not balance out those they burn from foraging for them, Live Science previously reported. The feet of the pizzly bear is extensive, having more familiarity with brown bears, and the claws are long, unlike polar bears. In 1991 one or more grizzly bears were documented hunting seals and polar bears on the sea ice near Melville island, over 500km from the mainland coast. Grolar (where the father is a grizzly) and pizzly bears (where the father is a polar bear) were first confirmed as a hybrid species in 2006 through DNA testing of a specimen shot in the. Possible wild-bred polar bear-grizzly bear hybrids have been reported and shot in the past, but DNA tests were not available to verify the bears' ancestry.

Polar bears have hairy feet, and their soles are completely covered in fur. There are other creatures that call our planet home, too. And, as they spend more time together, the likelihood of them interbreeding becomes higher. When polar bears and grizzly bears mate, the hybrid is called a pizzly bear, or a grolar bear. However, fur color is not the best-identifying characteristic, since occasionally there are also naturally-born blonde grizzly bears in the wild. Whereas a polar bear has an extended, sleek profile, the grizzly bear has a much rounder, thick head.

This precipitous fall is linked partly to the encroachment of grizzly bears into polar bear ranges, where they outcompete them for alternative food sources, but also to polar bears' highly specialised diets, as DeSantis highlights in research published on April 1 in the journal Global Change Biology. Genetic analysis has revealed multiple instances of introgressive hybridization between bear species,[4][5][6] including introgression of polar bear DNA into brown bears during the Pleistocene ("grizzly bear" is a local common name for Ursus arctos whereas "brown bear" is used internationally and in science to refer to the species as a whole).[7]. Since 2006, several confirmed and unconfirmed sightings of "pizzly bears" have been reported as climate change alters the habitat and habits of the two species. That year, Jim Martell thought he had shot a polar bear until officials noticed that the bear was white, it had a humped back, and its claws were much too long for the average polar bear.
