Objective: This study aims at determining the spatial distribution and period of activities of the forest elephant (Loxodonta africana cyclotis) at Taï National Park (TNP) to contribute to its conservation. Methodology and results: Observations of elephants at different locations and time periods were recorded by using 87 camera traps with date and time-stamped settings. Cameras were installed following a systematic placement approach, and their geographic coordinates were recorded using a GPS. After 120 days of trapping, we observed a high concentration of activities in the southern areas of the park. For the period of activities, we noted that observations of unit individuals were recurrent during the day while those of elephant groups were more important at night. Conclusion and application of the results: The south of the park where there is a large distribution of elephants would be more favourable to these animals. The small number and remoteness of large cities on the periphery of this area of the park could explain that pattern. The distribution and activity period information is useful for park surveillance by rangers. In addition, further studies are needed for a better explanation on the distribution pattern of elephants at TNP.

La connaissance du profil écologique de la faune d’un site est importante pour mieux apprécier la dynamique spatio-temporelle des espèces et les interactions entre elles. La présente étude a été réalisée au Parc National de Taï. Elle a pour objectif de déterminer les périodes d’activités nycthémérales et la structure sociale du céphalophe zébré et du céphalophe de Jentink. Au total, 291 pièges photographiques ont été installés suivant un dispositif systématique de mars 2019 à mars 2020. Le traitement des enregistrements vidéo obtenus a permis de montrer que le céphalophe zébré est préférentiellement diurne avec 84% des observations faites dans la journée. Les périodes d’activités maximales de cette espèce ont été marquées en début de journée de 6 à 8h et en fin d’après-midi de 15 à 17h. Par contre, le céphalophe de Jentink est principalement nocturne avec 83% des observations enregistrées la nuit. Cette espèce a été plus active autour de 2h, 4h et 19h. Cependant, ces deux espèces mènent une vie généralement solitaire avec parfois une formation de groupes de deux individus adultes. Pour le céphalophe zébré, 94,21% des individus vivent seul. Concernant le céphalophe de Jentink, 96,70% des individus solitaires ont été identifiés. The knowledge of the ecological profile of the fauna of a site is important to better appreciate the spatio-temporal dynamics of species and the interactions between them. The present study was carried out in the Taï National Park. Its objective is to determine the periods of nycthemeral activities and the social structure of zebra duiker and Jentink’s duiker. A total, of 291 camera traps were set in a systemic design from March 2019 to March 2020. The processing of the obtained video recordings showed that the zebra duiker is preferentially diurnal with 84% of the observations made during the day. The periods of maximum activity of this species were marked at the beginning of the day from 6 to 8 am and in the late afternoon from 3 to 5 pm. In contrast, Jentink’s duiker is mainly nocturnal with 83% of observations recorded at night. This species was most active around 2h, 4h and 19h. However, these two species lead a generally solitary life with sometimes a groups formation of two adult individuals. For the zebra duiker, 94.21% of individuals live alone. Concerning the Jentink’s duiker, 96.70% of the solitary individuals have been identified.
