Grizzly bears have also been seen in the province of Nunavut for the last 50 years. Perhaps a pizzly bear will have a less specialized diet than a polar bear, for example, so it could eat a wider range of different foods. This is another interesting blend of the two different parent species. Are Grizzlies and Polar Bears Hybridizing in Alaska? This polar bear-grizzly bear hybrid is called a pizzly bear, a grolar bear, a nanulak or a rare ursid hybrid. No one has been attacked by a pizzly bear, as far as records show; however, this is possibly due to the species low numbers. "Most of the time, hybrids are not more vigorous than either of the two species," DeSantis said, adding that individual species generally have adaptations best suited for their habitat. After some research and a DNA test, scientists concluded that the genetics were that of a polar bear and grizzly hybrid. Things are changing so fast, Shideler says. The bear also had a shallow face with brown fur around its eyes and nose. In fact, polar bears can swim for several days without stopping. 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. Other than its big brown paws, it has the white fur of a polar bear, only smaller sized. 41 Polar Bear Hybrid Premium High Res Photos - Getty Images A different species of bear would be the Brown Bear (AKA the Grizzly Bear).

Whats most important about this news, at least in my opinion, is how our actions and the resulting climate changes are affecting these animals. 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. With features that could give them an edge in warming northern habitats, some scientists speculate that the pizzlies, or "grolars", could be here to stay. Will it increase in frequency as polar bears spend more time on land? These eight species identified include four first-generation pizzly bears with a 50:50 split between brown and polar bears. Between 2012 and 2014 another six hybrid bears were either killed by hunters or live-captured by biologists. They are omnivores and feed on a variety of foods, including fish, berries, and carrion. [30] For example, their bodies are smaller than polar bears, but larger than grizzlies, while their heads fall between the broader grizzly head and the leaner polar bear head.

Grizzlies are illegal to hunt and could face a possible fine of $1,000 CAD or even jail time. Meanwhile, "polar bears are increasingly having to search for other food sources, when hunting seals from sea ice becomes untenable," she said.
