Ethogram is the basic of animal behavior research.The Chinese pangolin(Manis pentadactyla)is one of the pri-mary protected wild animals in China,and it plays the role of ecosystem engineer through burrowing and foraging.How-ever,due to its burrowing and hidden habit,it is difficult to be observed directly in the field.Most of the behavioral studies of the Chinese pangolin are based on the observation of the captive individuals.In order to explore the behavioral character-istics of wild Chinese pangolins,we deployed 269 infrared cameras near their burrows in the forest area of Heping County,Heyuan City,Guangdong Province from October 2020 to October 2022,and a total of 1,806 wild Chinese pangolin activity images were recorded and identified.Based on the three elements of"posture-act-environment"(PAE)and combined with its behavioral functions,the ethogram and PAE coding system of wild Chinese pangolin were constructed.A total of five postures and 33 actions of wild Chinese pangolins were recorded in nine environmental types.22 types of behaviors were divided into seven categories according to the behaviors,including vigilance,foraging,locomotive,digging,nesting,fam-ily and marking behavior.The construction of PAE behavior ethogram of the Chinese pangolin effectively filled the gap in the field behavior study,and provided basic data for the in-depth study of Chinese pangolin's behaviors.
