What Are Owl Boxes?

Construction

• Owl boxes should meet the following requirements to be adequate homes for displaced owls: Holes should be large enough for a barred, barn or screech owl to enter but not large enough for a great horned owl or predators to enter. Boxes should not feature a perch because owls do not need them and they may attract predators.

Cleaning

• Owl boxes should come equipped with a clean-out valve and should be cleaned annually between October and December.

Treatment

• Boxes should be made of woods treated with a waterproof non-toxic stain. Many stains can be toxic to owls and other birds. Consult a local hardware store to determine what stains are appropriate for an owl box.

Environment

• Most owls prefer to nest in wooded areas, near streams or water features. They do not thrive near human contact. Consult the local Audubon or birding society to determine if your property is ideal for birds.

Commitment

• Placing owl boxes on your property requires a commitment. Do not use pesticides on your property and commit to leaving the bird box alone from January to October. Owls do not like to be disturbed and find human contact stressful.

Mounting

• Owl boxes should be hung at least 15 feet above ground in a tree with an adequate amount of shade to protect the young from the summer sun. Boxes should be hung at least 75 feet off the ground if there is any chance of people coming near the trees.
