Homes for tawny owls
Tawny owls are the classic 'brown' woodland owls that make the characteristic owl hoot. They readily occupy large gardens with trees. They have a wide diet and will eat almost anything from worms to rabbits.
They are content to nest in smaller cavities than barn owls and the designs of the nestboxes reflect this. Both can be fixed to trees in woodland or in large gardens. Tawny owl chicks start to explore their surroundings well before fledging, and so the box needs to have nearby branches they can climb over.
Tawny owls are sensitive to disturbance when on eggs, and can also be aggressive. They can be dangerous if they or their young are approached, so it's best to leave them well alone while they are nesting. Because of this, the suitability of a site should be considered before putting up the box – eg. a garden with small children may be inappropriate.
Make a box
Here are plans for both a chimney nestbox and an 'upright' tawny owl nestbox - see which one works best for you.
Attach the chimney nestbox at 45° angle to a tree either with a batten of wood 100 x 710mm, or slung beneath a sloping branch.
