Burrow-sealing behavior of Transbaikal zokor (Myospalax psilurus) is considered as a adaption to long-term underground living. Some research suggests that sealing-behavior was caused by the zokors’ fear of wind and light. However this view lacked empirical evidence. A study using a 2×2 contingency-table design including 2 factors and 4 treatments was conducted in August, 2014 in a Hulunbuir pasture, Inner Mongolia to examine the burrow-sealing behavior of zokors. Sixty-eight zokors were randomly divided into 4 groups, and each group was subjected to 1 treatment. Data of burrow-sealing behavior were recorded and analyzed using mutual information analysis of Shannon information and chi-square test. The results show that combination of wind with light did not affect sealing behavior of Transbaikal zokor（I=7.22×10-5）; both wind and light had no significant influence on Transbaikal zokor sealing behavior (P﹥0.05) . These results indicated that sealing behavior of Transbaikal zokor did not correlated with wind and light.
