Did you know ermines experience a unique physical change in the winter months due to decreasing amounts of daylight, causing them to turn white? Ptarmigans and snowshoe hares also go through this seasonal change. If you're as excited for snow as this ermine appears to be, keep an eye on our social media and forest webpage. We'll add specific recreation and avalanche risk information as we move into winter ❄️ https://www.fs.usda.gov/flathead | The Forest Service - Flathead National Forest

The mountain ermine, also known as a stoat, has a fascinating seasonal coat change. In winter, it develops a pure white coat, blending perfectly with snowy landscapes for camouflage and protection from predators. This coat, called “ermine,” sometimes retains a black-tipped tail. In summer, its fur changes to a reddish-brown on the back with a white underside, helping it blend into the warmer, snow-free environment. This adaptation ensures the ermine stays concealed and safe throughout the year.
