Abstract: Observations on behaviors of Amur tiger in breeding seasons were made in a semifreeranging area at Taishan Amur Tiger Park from 2006 to 2007 with alloccurrence recording, focalanimal sampling and behavior sampling methods. Behavioral data were collected and coded following the “postureactenvironment” (PAE) coding system that concerns with posture, act, environment and ecological function of behaviors. A total of 14 postures, 47 acts and 98 behaviors were recognized and defined in our study. Based on ecological function of each behavior, all of the recorded behaviors were categorized into 13 groups including foraging, eliminating, thermoregulatory, paring, mating, parental, agonistic, affiliative, aggregation, communication, resting, locomotive and miscellaneous behaviors. The first behavior ethogram of semifreeranging Amur tiger in breeding season was then established following the PAE coding system.
