There aren't many species whose names change with the seasons. But the weasel, or stoat, is one of them. During spring summer and fall, the species sports a brown and cream coat. In the winter, however, its coat changes color to a pure, snowy white. With that color change comes a name change. In the winter months, the species is known as the ermine. So if you happen to see one bounding around this winter, you know what to call it!
