Update from the owner of site 9
Our red female owl from last year has been back in the box every night for the last 2 weeks! She has brought in a frog , a rat and a house sparrow. We have installed a bird cam in the box ( Spy on a Bird camera) so we can study the owls behaviors more closely. The gray male ( same one from last year) has been sleeping in the box for 2 nights in the last few days! It seems the pair are taking turns using the box which we hope is a positive sign that they will use our box again and we hopefully will have another successful breeding and fledging.
The male was hanging out with the snow on his head this am! he and the female are taking turns in the box!
