I made boxes for the birds in Goodenbergh Country Park and 3 years ago I made a Barn Owl nest box and placed it in a tree near to my wildlife hide.
The Jacdaw Squirrels and Stock Doves usually get in the box first but I got a really nice surprise when I was just sitting in the Deer hide. The sight of a Tawney Owl flying headfirst at the box and carrying a mouse in for what looks like young.
I can’t wait to see if the family are successful and rear a family for the good of the site. I have only seen your Owls about 5 years ago. Keeping very quiet I sat and watched the male come out of the box and sit there for a good 10 min then it flew into a tree next to me just out of sight.
