Abstract:

The Sunda Scops Owl, also known as the Collared Scops Owl, is the smallest owl species in the Strigidae family. Native to lowland areas up to 1300 meters above sea level in Southeast Asia, particularly in urban and stable environments, this nocturnal bird faces numerous challenges due to habitat loss, dwindling prey availability, and increasing light pollution. This paper explores the ecological significance of the Sunda Scops Owl, the impact of light pollution on its survival, and potential solutions to mitigate this threat.

Introduction:

The Sunda Scops Owl (Otus lempiji) is a fascinating species renowned for its distinctive "put...put..put.." call during the night. Despite its adaptability to urban and stable environments, the owl's survival is increasingly threatened by human activities, particularly light pollution. This paper aims to delve into the ecological importance of the Sunda Scops Owl, analyze the detrimental effects of light pollution on its habitat and behavior, and propose strategies to address this pressing issue.

Ecological Significance:

The Sunda Scops Owl plays a crucial role in maintaining ecological balance as a predator of small birds, insects, reptiles, frogs, and rodents (Ali & Ripley, 1983). By controlling these populations, it helps regulate the ecosystem and prevent the proliferation of pests. Additionally, its presence serves as an indicator of environmental health, reflecting the quality of urban and stable habitats (Wijesinghe & Goonetilleke, 2014). Protecting the Sunda Scops Owl is not only essential for its own survival but also for the overall biodiversity and ecosystem resilience.

Impact of Light Pollution:

Light pollution poses a significant threat to nocturnal species like the Sunda Scops Owl. Excessive artificial light disrupts their natural behaviors, including hunting, mating, and nesting (Longcore & Rich, 2004). Bright lights can disorient owls, causing them to collide with structures or become easy targets for predators. Moreover, light pollution alters the circadian rhythms of these birds, leading to physiological and behavioral changes that can ultimately affect their survival and reproductive success (Dominoni et al., 2013). As urbanization continues to expand, the intensity of light pollution escalates, exacerbating the plight of nocturnal wildlife.

Mitigation Strategies:

To mitigate the adverse effects of light pollution on the Sunda Scops Owl and other nocturnal birds, concerted efforts are needed at various levels. One approach is to implement lighting regulations and policies that promote responsible outdoor lighting practices. This includes using shielded fixtures, installing motion sensors, and reducing unnecessary illumination during nighttime hours (Gaston et al., 2013). Educating the public about the importance of dark skies and wildlife-friendly lighting can also foster community engagement and support for conservation initiatives.

Furthermore, urban planning should prioritize the preservation and restoration of natural habitats, including green spaces and native vegetation, to provide suitable foraging and nesting sites for nocturnal birds (Tremblay et al., 2016). Creating wildlife corridors and buffer zones between urban areas and natural habitats can facilitate the movement of wildlife while minimizing human-wildlife conflicts. Additionally, integrating ecological considerations into architectural designs, such as incorporating bird-friendly building materials and features, can help reduce the collision risk for nocturnal birds like the Sunda Scops Owl (Klem, 2009).

Conclusion:

The Sunda Scops Owl represents a unique and valuable component of urban biodiversity, yet its survival is increasingly jeopardized by light pollution and habitat degradation. By implementing proactive measures to reduce light pollution and preserve natural habitats, we can create a more sustainable and harmonious environment for nocturnal birds and other wildlife. Protecting the Sunda Scops Owl requires collective action and awareness to ensure its continued presence in our urban landscapes.
