Spotted owlet

Systematic position: The Spotted owlet (Athene brama) belongs to the order Strigiformes and the family Strigidae. While it is a predator, its interactions with agricultural environments often necessitate management, especially when birds establish habitats within storage infrastructure.

Biology and life cycle: This species is a small, sedentary owl found in open landscapes, scrubland, and human-altered environments. They nest in tree hollows or crevices in buildings. Their life cycle is adapted to permanent territories, meaning that once they occupy a farm building, they remain there throughout the year, which requires consistent management if their presence becomes problematic.

Nature of impact: The Spotted owlet does not feed on crops, so it is not a direct threat to plant cultivation. However, its presence in grain silos, warehouses, and processing facilities is considered detrimental due to sanitary contamination. Fecal matter and feathers contaminate stored grain, leading to potential quality degradation and failure to meet agricultural safety standards.

Agricultural significance: Outside of storage facilities, the Spotted owlet serves a positive role as a biological control agent. By hunting rodents, it significantly reduces the population of mice and voles that destroy field crops. Thus, they are often considered beneficial in the field, while being a nuisance inside specific industrial agricultural buildings.

Control measures: Management strategies focus on exclusion rather than eradication. Since these birds provide valuable rodent control, they should be discouraged from entering sensitive areas rather than culled. Effective measures include installing fine-mesh screens over ventilation ports, sealing structural gaps in walls, and maintaining clean warehouse environments to reduce attractants for nesting.
