Keep in mind that the barn owl is likely more common than suspected in most areas.For an example, click on the link under the state of Washington below for a typical pattern of barn owl range in a mountainous state. Barn owls do not inhabit forests or most cities. In states that show medium to high populations of barn owls, take into account barn owl preferred habitat.Again, nest box programs in such states are encouraged by wildlife officials. Also, some states that have suffered declines may have increasing populations of barn owls due to habitat restoration, such as Pennsylvania where the Pennsylvania State Game Commission is reestablishing many acres of wild grasslands throughout the state.It is these populations that can be expanded through nest box programs. Ohio is an excellent example where certain counties have fair numbers. Even in states that show rare or low populations of barn owls, there may be pockets of populations.There are several things to keep in mind while looking at a range map such as the one above. Excellent states to use barn owls in sophisticated rodent control programs. In such states, barn owls will tend to have more than one brood per year. Light Blue: Fair populations these states offer excellent opportunities to establish robust populations of barn owls for natural rodent control and integrated pest management.ĭark Blue: Good populations these states have such high populations of barn owls that nest boxes are inhabited relatively quickly and occupied at relatively high rates. They are excellent states for conservation oriented nest box erection programs in areas of good barn owl habitat. Yellow: Species of Special Concern these states have seen declining populations. Pink: Endangered these states may have already suffered such losses of barn owls that habitat restoration combined with nest box programs may be necessary to bring back any numbers. This color-coded map outlines the population status of barn owls throughout the United States.
