The Western screech owl is a nocturnal species. They leave their roost at around sunset in order to forage and come back during sunrise. They are socially monogamous, but both male and female mate outside the pair. During courtship, they sing together, and male present food to the female. During this time, males tend to roost near their nest. Near the end of the nesting period, the female also leaves the nest and roost with the male. Both parents guard their nest entrance against predators like jays, crows etc. They perch unnoticeable on trees and keep a good eye on the ground in search of prey. At times, they also perch on creeks looking for crayfish. They are capable of catching flying insects or bats in the air.

Courtship displays include clicking of the bill, bowing, bringing food to the female, preening each other and calling together. Females lay 2 to 6 white colored, eggs following copulation. Incubation goes on for 26 days on average, and it is done by the female. The male brings food for the female during this time, The female does not leave the young ones for the first three weeks. The owlets leave the nest after four weeks from hatching. However, they stay with their parents for another five weeks or so.
