Abstract

Two weasels Mustela nivalis (L.) were observed on April 4 and 18, 1992, respectively, in the western parts of Hardangervidda, southern Norway. The weasels were both in summer pelage (walnut brown above and white below), in a season when the weasel normally has a completely white coat. The first observed weasel was caught, and age-determination showed that it was born during the early winter months. Thus, summer pelaged weasels in winter are a strong indication of successful winter reproduction.
