At the same time grizzlybearsare moving north and, in some cases, mating with polarbears, creating a hybrid animal known as apizzlybear. And other studies are coming out even, you know, just recently showing that they're trying to eat you know, seabird eggs and not very effectively or, you know, whatever they can sort of scrounge around and and that's one of the things that is really kind of challenging for this polar bear is because it has this elongated skull, it's not well suited to eating just sort of any type of food source, right? This particularly unfortunate creature wandered into the .

These bears can be identified by their creamy white fur with brown patches around their eyes, back, and feet.

Derocher, a professor of ecology at the University of Alberta, would later learn that the bear was the first known grizzly bearpolar bear hybrid found in the wild. And so it's sort of having to scavenge potentially, to find different food resources. Scientists were shocked again by the discovery of second and third generation Pizzly and Grolar Bears [4].

Observations made in captivity and a study conducted in the wild also suggest that the hybrids are fertile and have themselves produced young. "We're having massive impacts with climate change on loads of species right now," DeSantis said. This is likely partially driven by territoriality as well as to avoid inbreeding. Or, you can make a right turn and head down towards Churchill, Manitoba. Paleontologist Larisa DeSantis joins Host Bobby Bascomb to explainmore about these hybrid creatures. An odd-looking bear shot last week by a hunter in Nunavut has turned out to be a grizzly-polar bear hybrid a rare find that a researcher says is becoming more common .
