Banff National Park is reminding visitors about wildlife safety, using an amazing close-up photo of a grizzly having its lunch. The agency posted the trail-cam photo on Facebook on Tuesday. In it, the grizzly is looking right at the camera, munching on a fish. “With prolonged cold temperatures, thick ice and snow can cover entire lakes, resulting in reduced oxygen levels as consumption exceeds production. This process may result in a natural fish kill, providing an easy, seasonal meal for many wildlife species like scavengers and birds, not just for bears,” the park said in the post. “Moments like this are best left undisturbed. Always respect wildlife closures.” Officials said it’s important to stick to the rules whenever they come across animals feeding in the park. “Wildlife needs space, especially when feeding during spring when food is scarce,” the statement continues. In Banff National Park and other mountain parks, visitors should never: According to park rules, all visitors should stay at least three bus lengths away from deer, elk, sheep and moose, and 10 bus lengths away from bears, wolves, cougars and coyotes. More information on bear safety and important bulletins for guests can be found on the Parks Canada website.
