January in Yellowstone National Park reveals two remarkable winter hunters: the North American river otter and the red fox. While otters navigate icy rivers in search of fish, foxes patrol snow-covered meadows, listening for rodents hidden beneath the surface. Both species possess extraordinary adaptations that allow them to survive Yellowstone's harsh winter conditions. For wildlife photographers, these animals offer opportunities to capture hunting behavior, movement, and the contrast between wildlife and the frozen landscape. In this edition of The Wild in Yellowstone, we explore where to look for river otters and red foxes, how their seasonal behavior changes during winter, and the camera techniques that help capture their most compelling moments. From otters sliding across snow to foxes diving after prey, January offers stories worth discovering.
