The weasel can be found all over Finland. The weasel lives wherever its main source of food, small rodents are to be found. Weasels catch voles in bushes and tall grassy areas, felling openings, edges of swamps and forests, fields and even in outbuildings. Though the weasel is active at all times of the day, it can rarely be spotted: the smallest predator in all of Europe travels nimbly through rocky terrain and all sort of vegetation, staying even in the tunnels dug by voles, safely out of sight from humans. The weasel stores its surplus food for the rainy day.
The weasel is a protected species in nature conservation areas.
