Half-grizzly half-polar bear hybrid

Here's the story:

Officials seized the creature after noticing its white fur was scattered with brown patches and that it had the long claws and humped back of a grizzly. Now a DNA test has confirmed that it is indeed a hybrid -- possibly the first documented in the wild.
"We've known it's possible, but actually most of us never thought it would happen," said Ian Stirling, a polar bear biologist with the Canadian Wildlife Service in Edmonton.
Polar bears and grizzlies have been successfully paired in zoos before -- Stirling could not speculate why -- and their offspring are fertile.

It seems to me it would be a lot more useful for all the Bigfoot-hunting types to go looking for rare hybrids. We would certainly learn a lot more from it.
