Knowra Stoat Stoat The stoat (Mustela erminea), also called the ermine, is a small, slender carnivorous mammal in the weasel family. In many northern regions its coat turns white in winter, often leaving the tail tip black.
Seasonal coat color change : A recurring change in an animal’s coloration associated with seasons. Stoats in snowy regions replace brown fur with white winter fur.
Mustelidae : A family of carnivorous mammals that includes weasels, otters, badgers, martens, and wolverines. The stoat belongs to this family of elongated, mostly predatory mammals.
Ermine fur : The white winter pelt of a stoat, traditionally valued for its soft fur and black-tipped tail. The stoat’s winter coat became a distinctive material in European ceremonial dress.
Stoats in the Scottish Highlands : Stoats living in the uplands and lowlands of Scotland, where coat color varies with local snow conditions. Their winter coats do not always turn fully white where snow is unreliable.
Photoperiodism : A physiological response to changes in the length of day and night. Day length helps time the stoat’s seasonal molt.
Weasel : A common name for several small, slender mustelids, especially species in the genus Mustela. Stoats are often called weasels, but the names can distinguish different species.
Royal ermine : A pattern of white fur marked with black tails, used in European regalia and heraldry. The stoat’s winter pelt supplied the pattern’s characteristic black marks.
Stoat in the Isle of Man : The stoat population established on the Isle of Man, where animals have a distinctive local history. This island population is a notable example of stoats living outside their mainland range.
Mustelid locomotion : The movement patterns and body mechanics characteristic of mammals in the weasel family. The stoat’s long, flexible body supports quick movement through narrow cover.
Least weasel : A small mustelid, Mustela nivalis, found across parts of Europe, Asia, and North America. It resembles the stoat but is generally smaller and lacks the stoat’s black tail tip.
