Identification: Smallest weasel; upper body chocolate brown to sandy tan, venter white or yellowish color; patches of brown; tail brown and short, lacking black tip. Winter color is white.
TL: 190-215mm (males),
Occurs across North America from Alaska to Maine, and as far south as Georgia
Habitat: Can survive in a wide variety of habitats, including open forests, farmlands; prefer marshes, grasslands and shrubby areas and try to avoid deep forests and sandy deserts.
Voles and mice are most of diet, but also eat insects, small ground nesting birds and their eggs. Have to eat their total body weight daily to survive because of small size and rapid metabolism.
Reproduction: Nests in abandoned rodent burrows of ground cover; produce two or more litters a year; 1-6 young in each litter; young are born naked and blind; female take care of young for about 12-14 weeks.
Conservation: Found statewide but uncommon.
Other: Rarely trapped; Inuit had great respect and the capture of one is considered a good omen. Have glands for defense and marking territory. Do not suck blood.
