Where to put an owl nest box
The ideal nesting box site locations are in a shaded area, 16 feet off the ground. Pole mounted nest boxes can be placed out in the sun...if no shade is available. Trees are the natural site location as the birds most often are found inhabiting hollow tree trunks and branches. Trees also provide shade throughout the year.
You can have up to 6 owl nest boxes per mile, according to the Dept. of Agriculture.
