Site 1 and Site 3,
Just a bit early but had 2 boxes with screech owls spend the day on Sunday Sept 23rd, 2018. This is the first Screech owl activity at Site 1 since April 2015. Hopefully the owl will stick around and set up a territory, and not just traveling through the area. Based on the screen capture of the in box camera, it does look like a red phase.
Site 3. Had an owl take up residence in July last year, this could be one of the pair last year, as they were a red phased pair (pretty sure).
