Barn Owl nest box networks

Barn Owls are voracious predators of common rodent pests, especially gophers, voles, and mice. The presence of Barn Owls is found to be associated with decreased pest activity and increased yields in agriculture in a variety of studies conducted locally and abroad.

Because large tree cavities and old barn structures are scarce on the landscape, Barn Owls will readily nest in provided nest boxes in agricultural and some urban areas.
