The males mainly sleep in the evening, and begin and end to move later 1 hour or so than the females. Variation of individuals and sexes, which were analyzed with one way ANOVA, indicates that there are clear differences in moving ( P <0 05) among individuals,and in sleeping,resting,moving and other behaviors ( P <0 05) between the male and female Amur tigers.
