Barn Owls nested in this owl box in 2011 and are also using it in 2012. I first noticed Barn Owls at this box on June 9, 2011, when I was driving by at night. I parked and could hear owls (young?) calling in the box – I imagine they were “scheuh”-ing but I didn’t describe the calls in my notebook. I could see an adult Barn Owl in the box on June 16 and also got a brief view of a second owl. I thought it was a nestling but wasn’t sure. I went to check it out at night and could hear “scheuh”-ing coming from the box. However, I couldn’t see any owls and no adults came to box while I was watching. The next day, I could see an adult in the box once again.
So far in 2012, I've seen an adult in the box on May 11 and 31, and on June 11; all of these observations were during the day. The pictures were taken on June 16, 2011.
