Weasels are adaptable and very active mammals. They hunt both at night and during the day, and rest in dens made in holes in the ground, piles of rocks or hollow stumps. Their diet usually consists of rodents such as mice and voles, with addition of birds or eggs when available. Weasels may be easily mistaken for stoats due to their similar appearance, however weasels lack a black mark on the tip of the tail, which is present in stoats.
