Nocturnal Owls of Dong Phaya Yen: Barn, Typical and Eagle Owls

This article examines the morphological and ecological distinctions among three principal groups of nocturnal raptors Barn Owls (Tyto alba), Typical Owls (Strigidae) and Eagle Owls (Bubo spp.). The Buddharaksa Community Forest in Si Khio District, situated at the ecotonal boundary of the Dong Phaya Yen Forest Complex, serves as the primary field site. Long-term observations confirm the consistent presence of Barn Owls, reflecting the suitability of the area’s semi-forest, temple and community mosaic. In contrast, Typical Owls and Eagle Owls have not yet been recorded within the community forest, although ecological conditions in deeper sections of Dong Phaya Yen suggest potential occurrences in denser habitats with larger prey availability. The findings highlight distinct morphological traits such as the heart-shaped facial disc of Barn Owls, the circular disc of Strigidae owls and the prominent ear tufts of Eagle Owls alongside differences in hunting behavior, habitat preference, and spatial use. This comparative analysis enhances the understanding of nocturnal predator ecology in the Dong Phaya Yen region and provides a foundational dataset for biodiversity management and long-term monitoring of nocturnal birds in the Buddharaksa Community Forest.
