Abstract: The relationship between rutting behavior and social status of the males of Golden takin（Budorcas taxicolor bedfordi）was conducted at Foping National Nature Reserve during mating season May 31 to August 26，2004. Rutting behaviors of males mentioned here including watching，female chasing，sniff and flehmen，mounting，ritualized fighting / fighting，and social status of male here was either in breeding herd or in solitary. Effort locating takins was made in transects along ridge of the peaks above 2 400 m in elevation. Whenever，animal was encountered the following data were recorded, age and sex，group size and component,social status of males，mutual behaviors of male / male，male / female，and any events after male entering or out of group. In the meanwhile，we recorded behavior of males in breeding groups. Data were summarized by every ten days. Total of 277 males were recorded and 241 times of rutting behaviors of males were recorded. The maximum number of rutting behaviors（105 times）was observed during 10 days between 21 and 30 of June. However,over 80% of total rutting behaviors were accumulatively occurred with in 20 days from May 21 to July 10. Solitary males were accumulatively as many as 30. 32% during the whole rutting season，however，72.62% of them occurred in the duration of June 10 to July 10. The peak of solitary males（50.67%）presented between 21 and 30 of June. The proportion of solitary males was significantly related to the rutting behaviors. This relationship may indicate that male initiatives to be solitary and move between breeding groups to seek more mating opportunities in breeding season. Our data does not support the opinion that solitary male was the loser in mating contests.
