Habitat
Common weasels inhabit a variety of environments including grasslands, farmlands, woodlands, and shrubby areas across Europe, North Africa, and northern Asia. They prefer habitats with ample cover such as hedgerows, rock piles, and dense vegetation for hunting and shelter. They are adaptable to both rural and suburban areas as long as prey is available.
Diet
Common weasels primarily eat small rodents like voles and mice, as well as rabbits, birds, eggs, and occasionally insects or frogs. They are voracious hunters, often killing more prey than needed and caching excess for later. Feeding occurs mainly at night, with weasels using their agility to chase and overpower prey in burrows or under cover.
Behavior
Common weasels are solitary animals that maintain exclusive territories, marking them with scent to ward off intruders. They are primarily nocturnal, actively hunting at dawn and dusk with quick, darting movements. Despite their small size, they exhibit bold and aggressive behavior when threatened or competing for food.
Conservation Status
The common weasel is classified as Least Concern by the IUCN, with a stable population trend across its wide range. Major threats include habitat fragmentation from agriculture and urbanization, as well as roadkill and secondary poisoning from rodenticides.
