Buck (short for Buckminster) was a weasel that makes an appearance in Ice Age: Dawn of the Dinosaurs.

Originally, the name "weasel" was applied to one species of the genus, the European form of the Least Weasel (Mustela nivalis). Early literary references to weasels, for example their common appearances in fables, refer to this species rather than to the genus as a whole, reflecting what is still the common usage in the United Kingdom. In technical discourse, however, as in American usage, the term "weasel" can refer to any member of the genus, or to the genus as a whole.

这是《冰河世纪》第三部中的新角色，一只叫做Buck的鼬鼠，这位疯疯癫癫的独眼龙老兄是不是让你想起了《狮子王》中经典的猫釉丁满咧？

鼬鼠有一种体形很小的黄鼠狼，它广泛分布于亚北极地区的丛林中，有时也穿越丛林的边缘进入北极苔原，但严格说来，它们算不上是北极居民。常年生活在北极草原上的最小的食肉动物是鼬鼠，或称之为貂，它们才是真正的北极居民。
