Openings and holes to attract Barn Owls
Barn Owls are interested in openings and holes rather than buildings or boxes.
A suitable entrance needs to be visible for a Barn Owl to explore potential nesting and roosting spaces.
Tree holes can be perfect roost sites for Barn Owls.
Large cavities may also be used for nesting.
Gaps between bales can also make cosy roost places.
Barns are potentially attractive…
…particularly if access is easily visible…
…from open countryside.
Even small holes may be noticed, like this one.
Or ventilation slots in traditional barns.
The minimum size a Barn Owl can access is only 70mm x 70mm!
Derelict buildings are just as attractive…
…as long as there’s a dry place to roost…
…that’s more than 10′ (3m.) above the ground
Cavities within buildings are preferred.
And suitable spaces may well be used for nesting.
Eventually however derelict buildings can become unsuitable for Barn Owls…
…because there isn’t anywhere dry enough to roost.

Fortunately, holes can be made in almost any type of building, even modern ones!
