This cute little guy is a long-tailed weasel at Bear River Migratory Bird Refuge in Utah. While he might look sweet, the long-tailed weasel is fierce. The sharp teeth, keen eyesight and scrappy character make this species a highly skilled predator. During the winter, their fur changes from brown to white to better protect them. Photo by Jana M.
