Habitat
This subspecies primarily inhabits forested areas, including mixed deciduous and coniferous forests, as well as grasslands and mountainous regions in Taiwan. They prefer environments with dense undergrowth for cover and proximity to water sources. Their range is mainly in the central and eastern parts of Taiwan, from lowlands up to elevations of about 3,000 meters.
Diet
The Taiwanese kolonok feeds mainly on small mammals like rodents and voles, birds, eggs, and insects such as beetles and crickets. They are opportunistic hunters, also consuming amphibians, reptiles, and occasionally fruits or berries. Feeding occurs primarily at night, using their keen senses to stalk and pounce on prey.
Behavior
These weasels are solitary and territorial, marking their areas with scent glands to deter rivals. They are primarily nocturnal, spending days in dens made from burrows or rock crevices, and exhibit agile climbing and swimming behaviors to hunt or escape. During mating season, males may travel more widely in search of females, but otherwise, they avoid social interactions.
Conservation Status
The Siberian weasel as a species is listed as Least Concern by the IUCN, but the Taiwanese subspecies faces potential threats from habitat loss due to deforestation and urbanization. Population trends are stable overall, but local declines could occur from trapping for fur or pests.
