Abstract
BACKGROUND: This study aimed to document the occurrence of the Egyptian fruit bat Rousettus aegyptiacus in King Salman Bin Abdulaziz Royal Nature Reserve (KSRNR), Hail region, Saudi Arabia, where its presence had not previously been confirmed. METHODS: Field surveys were conducted in the Hail region, and direct observations were documented using photographic and video evidence. The colony was visually counted in the field during a single daytime visit from an estimated distance of 15 meters. RESULTS: More than 50 individuals, including adults and juveniles, were observed roosting in a rock crevice. The photographic documentation confirms the presence of a colony of R. aegyptiacus in this area, extending the known distribution of the species into a previously unrecorded region of Saudi Arabia. CONCLUSIONS: These findings provide the first photographic record of R. aegyptiacus in KSRNR and highlight the species' ecological use of arid rock crevices. The results emphasize the need for targeted surveys and long-term monitoring to better understand the distribution and conservation of this species in desert environments.
