The Barn Owl: Friend of Agriculture and Communities

M. Allan Daly
Barn Owl

The Barn Owl is one of the most secret and highly effective nighttime predators in the world. This species is unrivaled in its effectiveness in controlling rodents such as mice and voles. It has been estimated that during a Barn Owl's approximately-10-year lifespan, it may eat approximately 11,000 mice. Only recently, however, has their place in the environment been celebrated, and it is a valuable resident on every farm property. This fact sheet will describe many aspects of the Barn Owl including identification, distribution, habitat preferences, food habits, and how to attract them to your property.
