Provide owl nest boxes (Tawny owl, Barn owl)
A small controlled study in 1990-1993 in Devon and Cornwall, UK (Ramsden 1998) found that activity in buildings used by barn owls Tyto alba as nesting and/or roosting sites dropped by 68% in nine areas following the conversion or demolition of the building, but was maintained in three other areas where a cavity and access hole were incorporated into the conversion or another nearby (<50 m away) building. There were no changes in eight control areas.
