Siberian Weasel (Mustela sibirica, 黄鼬).
Down by the Xiang river, the snow has revealed much of nature that usually remains hidden. A Siberian weasel made a rare appearance, exploring the piles of dead reeds along the mudflats. The weasel kept its distance from me, sometimes crawling slowly from bank to bank, sometimes standing tall to survey around, and sometimes dashing to exploring new drifts of reeds and snow—and scattering varied flocks of birds from its path.
