It is hard to tell with the photo being so dark, but it definitely could be a Barred Owl. The surest way to tell though is to Google" Barred Owl Cry" or "Barred Owl Vocalization" and find an audio file to play on the net (their are a few good ones on YouTube): They have a very distinctive hoot/cry/sound that is easy to identify. We have a pair that live in the trees over my chicken coop: I've only lost one chicken to them in nearly three years and he was a very small bantam rooster who was re-homed here and slid out of the run one evening unnoticed. We found him missing the next morning and a pile of feathers under the tree where the owls nest. They tend to be smaller owls and I rarely see them, but hear them every day.
The barn owl that lives around here is another matter entirely though. She, I'm assuming it's a she, is huge and hunts during the day sometimes. Except for the juveniles, all my birds free range during daylight hours. I had to watch helplessly as she plucked one of my French Guineas off the horse paddock fence this summer: He was about 8 pounds and she whisked him off like it was nothing. After that and a sudden influx of hawks (not uncommon to have over a dozen in the sky over my place), I decided to invest in a BIG pair of geese. I have seen the Barn owl in the trees a few times since then and if she tries to so much as fly over the geese raise a ruckus. So far, they have been excellent deterrents for the flying predators.
Good luck with your owl and I really hope it turns out to be a Barred Owl. If you have to have one living at your place at least these are small!
