Barred owls are crepuscular, this means they are mainly active at dawn and dusk. During the day they are difficult to see, due to them preferring to roost on branches or tree cavities. Nesting for these owls, abandoned nests are typically used for their young. The nests are aggressively protected from predators. Nests are preyed on by large owls, hawks, raccoons, and great horned owls that will eat both the young and the adults.
