Key findings

Day vs. night habitat use: Barred owls’ home ranges were significantly larger at night than during the day, indicating different habitat needs between their active and resting periods. The research emphasizes that preserving green spaces in urban areas can have profound effects on nocturnal and diurnal wildlife.

Energy efficiency in preferred habitats: Owls expended less energy in their preferred nocturnal habitats, suggesting that these areas provide higher-quality resources.

Affluent neighborhoods attract barred owls: Barred owls in Baton Rouge, Louisiana, showed a marked preference for habitats in affluent neighborhoods, supporting the “luxury effect”—the tendency for wealthier areas to harbor greater biodiversity.

Implications for Urban Design: The study advocates for providing and protecting habitat for barred owls to keep this important species, other forest-associated species, and the ecosystem services they provide present and functioning in urban areas. The study also advocates for the equitable distribution of green spaces in cities, especially in less affluent areas, to promote biodiversity throughout the urban landscape.
