The rock hyrax (Procavia capensis) exhibits varying thermoregulation and foraging habits between seasons, which reflect the rock hyrax’s overall behavior and energy budget. However, this relationship has not been sufficiently studied in Tanzania, as rock hyraxes are among the least studied mammals in East Africa. This observational study was conducted during a 10-day period in November 2025 on the kopje at Buti Main Gate in Randilen Wildlife Management Area (WMA) in Tanzania. The objectives were to analyze the social behavior and energy budget of rock hyraxes during the dry season at the gate of Randilen WMA and determine whether it differs from that of the wet season. Scan sampling was conducted twice daily (morning and evening) every 5 minutes to observe the behavior and activity state of all visible rock hyraxes. This rock hyrax population ranged from 43 to 116. Data were categorized by age class (adults, juveniles, and both) to determine how often rock hyraxes were inactive versus active and socializing versus isolating. We found that while rock hyraxes were primarily inactive and social year-round, they were more frequently observed active and isolating in the dry season compared to the wet season. Juveniles were primarily observed foraging, whereas adults were frequently seen resting alone in shady areas during hotter times of the day. These results suggest that the conditions in the dry season can significantly reduce rock hyrax social behavior and increase the amount of time spent in an active state, especially for juveniles. The increased energy budget of juveniles in this dry season study challenges previous studies which show that rock hyraxes are primarily inactive, thus warranting future research.
