Quick Summary

The long-tailed weasel (Neogale frenata) is a common mammal found from southern Canada to northern South America. It is an aggressive carnivore that primarily feeds on rodents and other small mammals. These weasels are typically brown above and white or yellowish below, with their coloration often changing to white in winter in northern regions. They can range from 15 to 23 inches in length, including a tail that is usually 3.5 to 6.5 inches long and tipped with black. The long-tailed weasel is also known as the bridled weasel due to facial markings that are often present, especially in southern populations. Weasels, in general, are known for their slender bodies, short limbs, and sharp claws.12
