Wildlife photography of a white long-tailed weasel standing in snow in Yellowstone National Park

A weasel blends beautifully into his surroundings in winter white camouflage. Only long-tailed weasels like this one in snowy regions change their color in winter, much like their short-tailed cousins, which are called ermine in their winter pelage. Only the black tip of their tail remains unchanged while the rest of the weasel turns completely white. While adorable, weasels are muscular, ferocious, and fearless carnivores. Their natural enemies are owls, hawks, and foxes. But this is where their black tail tips come into play—experiments have suggested that the contrasting black tip may draw the attention of an attacking predator away from the weasel’s body, making it more likely that the attack might miss altogether.
