Description: Like the similar, but smaller ermine, the long-tailed weasel has a brown back and light to cream belly. The tail is tipped with black. In winter, they turn snow-white with the exception of that black tip.
The long-tailed weasel is the southern relative of the ermine. It is found throughout the United States, with pockets in the southern Canadian Rockies.
The slight size advantage of the long-tailed weasel over the ermine allows it to take larger prey such as snowshoe hares. It will eat a wide variety of mice, voles, ground squirrels, pikas, small birds and grouse, and occasionally snakes or berries.
Like the ermine, they mate in they mate in the spring and summer, with implantation delayed until March. They give birth in May to between 3 and 9 offspring.
