A wildlife photographer says he's worried about a rare white grizzly living in mountain parks in Alberta and British Columbia after watching people get too close to it and seeing it run across a highway. The bear, which has been nicknamed Nakoda by locals, was first revealed publicly after it was spotted in Banff National Park in Alberta two months ago. Parks Canada said it's not an albino, but a natural colour phase variation that makes the 3 1/2-year-old bear white.
