Marmot

Very cute and curious. Also not dangerous.

Coyote

Interesting to contrast with wolf and fox. I read the coyote has a long nose and tail always held low, which you can clearly see here. Bigger than a fox, smaller (much) than a wolf. And that wolves hate coyotes and will kill them whenever possible.

Fox

Proudly bringing home the bacon.
  

Grizzly

Youngster grazing, taken through a scope.

  

Wolf

Hayden Valley alpha male, seen twenty miles down the road two days earlier. There is a huge collar around his neck. Personally I think they look like dogs and I want one.
