Abstract: The activities rhythms of argali were studied in Mt. Kalamaili Ungulate Nature Reserve(MKUNR) from March 2012 to March 2013.The behavioral observations followed the group scan sampling method and focal sampling method. The results indicated that argali have similar activity pattern in different seasons,but significant seasonal difference between male and female argali was also detected on the activities rhythms. The forage activities took a greater proportion during all seasons(about 50%). There is significant difference between male and female argali on the foraging activities(P<0.01),The relax activities also took a greater proportion during all seasons. There is significant difference between male and female argali in Summer and Autumn(P<0.01).For the diurnal rhythms,males and females spent more time in foraging and bedding,and males spent more time in bedding than females. The behavior synchronization index of groups indicated significant difference in the synchronization of male,female and mixed groups. The activities synchronization levels of same-sex groups were higher than mixed-sex groups. And the significant difference was also detected between males and females on their behavior individuals in mixed group, while males and females were just the reverse(female groups and mixed groups:χ²=14.976,df=1,P<0.01;male groups and mixed groups:χ²=10.472,df=1,P<0.01). Additionally,significant difference was also detected between males and females on their behavior synchronization index.
