Nest boxes in Ohio are helping increase the barn owl population dramatically
Once very common in Ohio, barn owl populations dwindled since the 1950’s. Now the barn owl is making a dramatic comeback in the state, due to nest box programs being conducted by the Ohio Department of Natural Resources Division of Wildlife.
Since 1988 agency biologists have installed nest boxes on more than 400 barns. The number of nests known nests increased from 19 in 1988 to more than 100 in 2012, and that number is only increasing. Biologists believe many nest in areas other than these boxes.
Barn owls are doing particularly well in the southwestern region of the state in counties that border the Ohio River. But other rivers, orchards, cattle farms, and hay and wheat fields throughout the state also provide good habitat. Corn and soy farms, on the other hand, attract few of these owls.
The benefit to farmers in the region has high potential. One barn owl family will take approximately three thousand rodents per year, mainly voles, mice, and rats. These pests can breed out of control and eat huge amounts of grain, girdle trees in orchards, and cause untold damage to floors and wiring in barns and outbuildings. A family or two of owls on a farm can make a noticeable difference.
The Ohio DNR encourages residents to install nest boxes in good habitat. Reporting sightings of barn owls helps the Division of Wildlife biologists estimate how many live in Ohio. This information benefits conservation efforts by tracking where and how the owls live. People who have barn owls living near them, they are encouraged to call the ODNR Division of Wildlife at 800-WILDLIFE (945-3543) or email firstname.lastname@example.org.
