ECOLOGICAL RESEARCH OF SOLITARY TAKINS IN WINTER IN TANGJIAHE NATURAL RESERVE
唐家河自然保护区冬季独栖羚牛及其习性

From the winter of 1987 to the early spring of 1988, we had been observing the solitary takins (Budorcas taxicolor) in the Tangjiahe Natural Reserve and achieved the material on their number, distribution and action laws in winter. Further more we still had done deeper researches on their behavioural (cology, overwintering adaptation and the limited factors of their death. All these takins are either old or weak or ill or physically disabled. They leave their clump and live alone. It is an inevitable law in their individual development. That they arc getting weaker day by day and arc on the verge of death is also an inevitable tendency.
