Mikä on Suomen yleisin näätäeläin?
The least weasel has a typical mustelid territorial pattern, consisting of exclusive male ranges encompassing multiple female ranges. The population density of each territory depends greatly on food supply and reproductive success, thus the social structure and population density of any given territory is unstable and flexible. Like the stoat, the male least weasel extends its range during spring or during food shortages. Its scent marking behaviour is similar to that of the stoat; it uses faeces, urine and anal and dermal gland secretions, the latter two of which are deposited by anal dragging and body rubbing. The least weasel does not dig its own den, but nests in the abandoned burrow of another species such as a mole or rat. The burrow entrance measures about across and leads to the nest chamber located up to below ground. The nest chamber (which is used for sleeping, rearing kits and storing food) measures in diameter, and is lined with straw and the skins of the weasel's prey.
