Hunter kills grizzly-polar mix
Fri., May 12, 2006
TORONTO – A DNA test has confirmed what zoologists, hunters and aboriginal trackers in the far northern reaches of Canada have dreamed of for years: the first documented case of a grizzly-polar bear in the wild.
Roger Kuptana, an Inuit tracker from the Northwest Territories, suspected the Idaho hunter he was guiding had shot a hybrid bear after noticing its white fur was spotted brown and it had the long claws and slightly humped back of a grizzly.
Territorial officials seized the bear’s body and a DNA test from Wildlife Genetics International, a lab in British Columbia, confirmed the hybrid was born of a polar bear mother and grizzly father.
“It’s something we’ve all known was theoretically possible, because their habitats overlap a little bit and their breeding seasons overlap a little bit,” said Ian Stirling, a biologist with the Canadian Wildlife Service in Edmonton, Alberta. “It’s the first time it’s known to have happened in the wild.”
He said the first person to realize something was different about the bear – shot and killed last month on the southern end of Banks Island in the Beaufort Sea – was Kuptana, the guide.
“These guides know their animals and they recognized that there were a number of things that didn’t look quite right for a polar bear,” Stirling told the Associated Press. The bear’s eyes were ringed with black, its face was slightly indented, it had a mild hump on its back and long claws.
Stirling said polar bears and grizzlies have been successfully paired in zoos and their offspring are fertile, but there had been no documented case in the wild.
Kuptana, a guide from Sachs Harbour in the Northwest Territories, was tracking with Idaho big-game hunter Jim Martell, who paid $45,450 for a license to hunt polar bears.
“It will be quite a trophy,” Martell told the National Post last week, even before the DNA results were in. He returned to Yellowknife for another hunt, this time for a grizzly bear. He told the newspaper he has dubbed the creature “polargrizz.”
Stirling said his colleagues have come up with a few names of their own for the hybrid: a “pizzly” or a “grolar bear.” One colleague suggested calling it “nanulak,” combining the Inuit names for polar bear – “nanuk” – and grizzly bear, which is “aklak.”
Colin Adjun, a wildlife officer in Kugluktuk on the northern mainland in western Nunavut, said he’s heard stories about an oddly colored bear cavorting with polars.
“It was a light chocolate color along with a couple of polar bears,” Adjun said. Though people have talked about the possibility of a mix, “it hasn’t happened in our area,” he said.
Three years ago, a research team spotted a grizzly on uninhabited Melville Island, 215 miles north of where Martell bagged his crossbreed.
Polar bear and grizzly territories also overlap in the Western Arctic around the Beaufort Sea, where the occasional grizzly is known to head onto the sea ice looking for food after emerging from hibernation. Some grizzly bears make it over the ice all the way to Banks Island and Victoria Island, where they have been spotted and shot.
That might explain how a grizzly got to the region, but few can explain how it managed to get along with a polar bear long enough to mate.
