Nest boxes have been attached to trees and inside barns to provide Barn Owls with suitable nest sites. Barn Owls have been seen flying at Trelusback on many occasions and have sometimes used the barns and nest boxes whilst roosting. To date these owls have not used the nest boxes for breeding.
The fields and scrub have been managed to encourage voles and mice which will provide food for the Barn Owls and other predators such as Kestrels and Buzzards.
In April 2023 a survey of the nest boxes was carried out and the boxes had been used by Grey Squirrels, Jackdaws and a pair of Tawny Owls. Three Tawny Owl chicks were ringed whilst the parents were absent from the nest.
