Each weasel has a territory of 10 - 20 acres (2.5 acres = 2 football pitches). Males' territories are larger than females' and they may overlap with one another. The size of the territory depends on the food supply; where there is plenty there is no need to hunt for food far and wide. The individual territories are marked with strong-smelling secretions from the anal scent glands. Females stay in their territory throughout the year, but during the mating season, males may travel long distances outside their normal range to find a mate. Weasels do not make themselves any kind of permanent burrow - they usually use the tunnel or burrow of one of the animals they have eaten!
