They both prefer to build their nests on deciduous trees like oaks, maples, and willows. They are however known to also sometimes nest in nest boxes, barns, sheds, and rocky ledges. Screech owl nests are built loosely and scantily made of materials like sticks, leaves, and feathers. The nests are usually found in cavities 6.5 to 20 feet above ground.

The nest boxes should be mounted at about 10 feet above ground or a little higher and should be placed near woodland edges or small tree stands near wetlands.

The Screech Owl Mating Habits

Eastern and Western Screech Owl The Eastern screech owl start the courtship ritual by having the male approach a female from a different branch until he gets close enough to bob and swivel his head before bobbing his entire body. The male sometimes even winks one eye at the female who can choose to ignore acknowledge him. If ignored the male will continue bobbing and swiveling until noticed. If the female accepts the male she responds by moving close and letting their bills touch. This signals the start of a lifelong partnership.



Western screech owls call to each other in a duet during courtship while approaching each other. They preen each other’s head and nibble their beaks. When the male changes his call to a rapid tremolo and the female to a short tremolo this signals that they are paired.

The Screech Owl Feeding Preferences

Both screech owls are hunters. They dive on their prey snatching it with their talons and eat it on the spot when small enough. Larger prey gets carried in the bill to a perch before it is devoured. They both eat a wide range of species but favor rodents, deer mice, large insects, and small birds.
