The most reported examples have been the three confirmed grizzly-polar bear hybrids.

Known commonly as a pizzly, prizzly, or grolar bear, the official name is simply "grizzly-polar bear hybrid".

A grizzly-polar bear hybrid is found on Banks Island in Canada's Northwest Territories.

Ursid hybrids, such as the grizzly-polar bear hybrid, occur between black bears, brown bears, and polar bears.

The first confirmed grizzly-polar bear hybrid found in the wild was shot on Banks Island in April 2006, near Sachs Harbour.

While grizzly bears and polar bears may have offspring, a grizzly-polar bear hybrid will likely be less suited in either of the ecological roles than the parents themselves.

This bear's body, neck and face suggest it may be a grizzly-polar bear hybrid, or 'grolar', living in the Arctic National Wildlife Refuge, Alaska.

April 16 - Hunter Jim Martell kills a Grizzly-polar bear hybrid on Banks Island in the Northwest Territories.

Recently DNA analysis of a bear shot by a hunter in the North West Territories confirmed the existence of naturally-occurring and fertile grizzly-polar bear hybrids.

Jim Martell, a hunter from Idaho, found and shot a grizzly-polar bear hybrid near Sachs Harbour on Banks Island, Northwest Territories reportedly on 16 April 2006.

The yellowish-white MacFarlane's bear, a mysterious animal known only from one specimen acquired in 1864, seems to attest that grizzly-polar bear hybrids may have always occurred from time to time.

A grizzly-polar bear hybrid (known as a pizzly bear or grolar bear) is a rare ursid hybrid resulting from a union of a brown bear and a polar bear.

There have been many theories concerning the origin of MacFarlane's bear, which include suggestions that it may have been a grizzly-polar bear hybrid, or even a surviving representative of a Pleistocene species.

A grizzly-polar bear hybrid (also pizzly bear, polizzly, prizzly bear, nanulak, Polar-Grizz, or grolar bear) is a rare ursid hybrid that has occurred both in captivity and in the wild.

Today, it is known that grizzly-polar bear hybrids do occur on occasion and that they match the specimen's description very well, notably the pale tan fur, and apparently also the oddly shaped skull which led Merriam to propose his new genus.

Polar bears can breed with brown bears to produce fertile grizzly-polar bear hybrids, rather than indicating that they have only recently diverged, the new evidence suggests more frequent mating has continued over a longer period of time, and thus the two bears remain genetically similar.

There's the pizzly bear, a cross between a grizzly and a polar bear.

A grizzly-polar bear hybrid (known as a pizzly bear or grolar bear) is a rare ursid hybrid resulting from a union of a brown bear and a polar bear.
