Owls hoot at night primarily to communicate, with their calls serving to mark territory, attract mates, and strengthen pair bonds. The hooting helps male owls announce their presence and readiness for courtship, while also warning other owls to stay away from their territory. This behavior is mainly nocturnal because most owl species are active at night, and the sounds travel better in the quiet night air without competing daytime noises. Additionally, calling at night reduces the risk of encounters with daytime predators. Some owls also hoot in other lighting conditions depending on their species and habits, but night is when hooting is most common as it aligns with their hunting and mating activities.
