  1. Order CarnivoraFamily Mustelidae • Large canines • No diastema • Claws not retractile • Mustelid glands • Short legs Taxidea taxus

  2. Order Carnivora Family Mustelidae Mustela erminea (Ermine) http://www.blueplanetbiomes.org/ermine.htm

  3. Mustela ermineaBy Julie Perrett ID: Short tailed weasel with a black tail tip and white feet. Tail is just over 1/3 body length. Males are larger than females. Summer - dorsum is dark brown, venter is white or yellowish. Winter - pure white coat with black tail tip Total – 240-330mm Tail – 60-95mm HF – 30-45mm Ear – 15-20mm Weight – 60-150g http://animaldiversity.ummz.umich.edu/site/accounts/information/Mustela_erminea.html

  4. Mustela erminea Distribution: Northern part of Western hemisphere. In Iowa found in Northern half of the state. Habitat: Found in a wide variety of habitats; woodlands, shrubby areas, lakes, marshes, rocky outcrops, open areas adjacent to woodlands, along wooded streams, and brushy fencerows. http://mbgnet.mobot.org/sets/taiga/animals/ermine.htm http://www.blueplanetbiomes.org/ermine.htm

  5. Mustela erminea Diet: Small mammals, birds, eggs, fish, frogs, invertebrates and young rabbits. Hunts both day and night.

  6. Mustela erminea Reproduction: • Promiscuous • Adults are generally solitary with discrete home ranges. • Den in old rodent burrows, tree roots, stone walls and hollow logs. • Nests are made out of fur, feathers, and grass. • Breed in early summer, gestation of 4 weeks. • Average litter of 4 to 8; born in April and May Conservation: Not considered endangered or threatened http://www.nenature.com/Ermine.htm

  7. Mustela erminea Other: • Lifespan of 1-2 years • Winter pelt prized • Can climb trees and swim • Large energy demands • Prey killed by powerful blow to the back of neck • Parasitized by a nematode that destroys sinuses • After mating (summer) development of embryos doesn’t occur until late winter or early spring (an 8-9 month period)

  18. Mustela nivalis (Least weasel) By: Lisa Hinote

  19. Mustela nivalis 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), 170-185mm (female) http://www.bozeman.k12.mt.us/wildlife/ http://www.blueplanetbiomes.org/least_weasel.htm

  20. Mustela nivalis Distribution: Statewide Occurs across North America from Alaska to Maine, and as far south as Georgia http://wildlife.wisc.edu/courses/301/mammals/maps/images/least_weasel.jpg

  21. Mustela nivalis 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. Diet: Carnivores 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.

  22. Mustela nivalis 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. http://homestudy.ihea.com/wildlifeID/058leastweasel.htm

  23. Mustela nivalis 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. http://www.enature.com/fieldguide/showSpeciesSH.asp?curGroupID=5&shapeID=1032&curPageNum=7&recnum=MA0453
