Abstract: The identification and classification of behavior is one of the premises and important contents of animal ecological researches. The most important condition for animal social behavior is identification of odor signals. Kinship is the process which individuals produce clues for identification. Kin recognition of Tupaia belangeri based on behavior and odor was measured in the present study. The results showed that circadian rhythm was observed in activating, resting, feeding and grooming behavior between kin and non-kin in Tupaia belangeri, which had bimodal type in activating, resting, and grooming behavior. It showed bimodal type in feeding behavior of kin Tupaia belangeri, but unimodal type in the non-kin T. belangeri. The selection of the urine, individual and cassette odors in T. belangeri was found significantly to their relatives compared with non-kin T. belangeri. All of the results showed that there had significant differences in the behavior patterns between kin and non-kin T. belangeri. Moreover, odor factors may have an impact in the kin recognition of tree shrews, such as urine and others.

Key words: Tupaia belangeri, kin recognition, behavior, odor
