Status and ethnobiology of Mountain Weasel Mustela altaica in Humla district, Nepal Yadav GHIMIREY* and Raju ACHARYA Abstract Information on weasels Mustela in the western Himalayas is scarce, so even small numbers of records of them are of high value. Frequent sightings of Mountain Weasel Mustela altaica during May–June 2013 in Humla, Nepal, indicated that it is common there, even around settlements. Ethnobiological observations revealed killing of the species for superstition, but probably not at levels damaging to the population.

This name might apply to all weasel species in the area, although discussions with local people suggested that no others occur. Mountain Weasel generates mixed responses: perceived useful because it kills rodent pests, people fear that these little predators eat dried meat stored in houses. Overall, it is unpopular in Humla, where dried meat is the most important protein source, re- believe that hanging a dried Mountain Weasel above the main entranceflecting the (Fig. lack 6) willof readily stop the available death of fresh new-born meat. children. Local people This belief reportedly becomes very important if more than one new-born child dies in a house. Two dried Mountain Weasels were seen in the village of Halji. This belief might apply to all weasel species in Nepal because weasel species seem to lack Fig. 2. Mountain Weasel Mustela altaica, Thadodhunga, Humla district, specific local names.
