Abstract Observations on breeding behaviors of Amur tiger were made at Heilongjiang Amur Tiger Park, Harbin from October 1998 to 2000,with random and instantaneous scanning sampling methods. During different phases, there were clear variations in behaviors of Amur tiger. The time budget of male and female Amur tiger were similar during rutting periods(P>0.05). Amur tiger spent most time in moving, more time in rutting, copulating and other behaviors, and less time in resting. During gestation periods, it spent more time in resting, moving, and less time in eating, standing, social and other behaviors. During parturition periods, it spent most time in resting, more time in moving, giving birth and other behaviors, and less time in eating. During nursing periods, it spent most time in resting, more time in nursing, moving, and less time in eating and other behaviors. For Amur tiger of 0～100 days, it spent most time in resting, more time in moving, eating, and less time in other behaviors. In activity rhythm, there were more significant differences in intensity, onset and duration of various behaviors. Resting and moving behaviors(P<0.001)showed more significant changes in different phases, and eating behavior(P<0.05)showed significant changes. In contrast, other behaviors(P>0.05)showed no significant changes.
