Look how the ermine wiggles his little nose! Ermines are a type of weasel, and in the summer their fur is brown with a white belly, but in the winter they're almost all white except for a black dot on their tails. This is actually a sneaky way to trick predators: In a snowy landscape, an ermine's enemies - like owls, foxes and coyotes - may lunge at the ermine's dark tail, but they'll miss the head and body.
Cooper was lucky enough to catch this friendly little guy in his cold-weather outfit. Looking good!
