Mountain goats in the Yukon, Canada

Nature's fluffy mountaineers. Mountain goats

Mountain goats like this trio in Canada's Yukon territory, aren't ovine but bovine. That is to say, they're related to antelopes and cattle, not goats and sheep. But these sure-hoofed creatures have no trouble climbing icy mountain slopes, taking slow steps as their white fur blends in with the subarctic snows.

They aren't confined to Yukon’s northern wilds, though: The mountain goat's habitat extends thousands of miles south into the US states of Washington, Idaho and Montana. There, these mountain bovines go by another name: Rocky Mountain goats, but they're still not goats.
