Not much is known about Owl courtship because many scientist haven't studied it. With night active owls, it’s probably due to the logistical challenge of doing research at night.
Most species of owls are most talkative in winter to early spring. This increase in vocalization signals the very beginning of courtship.(Owls can also be talkative in early fall, when they are establishing their territories for the winter)
Even in species where the male and female stay together all year long, the pair become more talkative at the beginning of the breeding season. Scientist think this chatty behavior helps strengthen the pair bond.
The pair may become more attentive to each other in other ways, such as perching close together.
Mutual preening is an affectionate-looking way for owls to cement their relationship. Ritual feeding is another important part of the courtship process for owls.
It’s not clear if the female owl judges whether her mate will be a good provider by the gifts he brings her. But his willingness to provide food for her-and her willingness to accept it-will be important in the weeks ahead. Because the female will rely on the male to feed her as she lays eggs, incubates them, and then broods the young owlets.
Copulation or mating (bonding) is called by ornithologist- treading. This takes place after the buildup of a courtship. In barn owls, a gift of food is the prelude.
