Sociable climbers. Mountain goats in Montana

These mountain goats are excellent climbers and often can be found on high cliffs in the Rocky Mountains and Cascade Range in the US and Canada, seemingly defying gravity on the sides of mountains. That's thanks to a special split hoof that allows them to grip rocky ledges. These plant eaters tend to spend most of their time grazing and looking for places to slurp up much-needed minerals.

This particular pair are in Glacier National Park in the US state of Montana, one of the best places to spot a mountain goat in the USA. Here, they are well accustomed to meeting humans and are happy to saunter right up to visitors. It’s in your interests to keep your distance, however. These guys can deliver forceful headbutts.
