In the verdant tapestry of Sri Lanka’s landscapes, the Brown Fish Owl (Ketupa zeylonensis) stands out as a formidable and intriguing figure. This large, nocturnal raptor is not only a marvel of biological adaptation but also deeply woven into the cultural and folkloric fabric of the island. From its impressive hunting techniques to its symbolic significance in Sri Lankan traditions, the Brown Fish Owl captures the imagination of all who encounter it.

The Brown Fish Owl truly comes alive in the twilight hours. Its scientific profile reveals an array of adaptations that make it a supreme predator. With a wingspan reaching up to 60 centimetres, this owl is well-equipped for flight in dense, forested habitats and near wetlands, such as Yala National Park, Wilpattu National Park, and Kumana Bird Sanctuary (BirdLife International, 2020). Its plumage, a mix of mottled browns and creams, allows it to blend seamlessly with the leafy surroundings, providing excellent camouflage.

One of the owl’s most remarkable features is its large, forward-facing eyes, which are adapted for optimal night vision. These eyes, with a high density of rod cells, are capable of detecting the faintest movement in low-light conditions (Winkler, 2018). This adaptation is crucial for spotting prey in the dark, where the owl relies on its keen eyesight and acute hearing. Its ear tufts, while not functional for hearing, add to its striking appearance and might also help in camouflaging against predators (Ferguson-Lees & Christie, 2001).

The Brown Fish Owl’s hunting strategy is a combination of patience and precision. It typically perches silently on a branch or a rock, scanning the water below for movement. With a sudden, powerful dive, it seizes its prey—primarily fish, but also frogs, small mammals, and birds (Ali & Ripley, 1987). The owl can be spotted near Udawalawe National Park’s water bodies and Sinharaja Forest Reserve. Its diet and hunting prowess emphasize its role as an apex predator and its importance in maintaining ecological balance.

In Sri Lankan culture, the Brown Fish Owl occupies a complex space between reverence and superstition. Owls are often seen as symbols of wisdom - with the influence of Western cultures - due to their keen senses and nocturnal habits (Saxena & Kumari, 2019). This perception is likely due to their ability to see and navigate the night, reflecting profound insight.

However, the same traits that inspire admiration also contribute to an aura of mystery and fear. In Sri Lankan folklore, the owl’s hoots are often interpreted as omens of bad luck or death (Dissanayake, 2021). This superstition is rooted in the owl’s association with the night, traditionally linked to the unknown and the mystical. The belief that the owl’s call heralds misfortune reflects the cultural ambivalence toward this fascinating bird.

Despite its cultural significance, the Brown Fish Owl faces numerous conservation challenges. Habitat loss, pollution, and human-wildlife conflict pose threats to its survival (BirdLife International, 2020). The destruction of wetlands and forests near areas like Bundala National Park and Gal Oya National Park due to agricultural expansion and urban development is particularly detrimental.

Conservationists are addressing these threats through habitat protection and restoration (Jayathilake et al., 2021). Educational programs are raising awareness about the ecological importance of the owl, dispelling superstitions, and encouraging coexistence between humans and wildlife.
