Owl House
A few years ago we decided to put a screech owl box in our big oak tree. We regularly hear them calling at night during the summer when our windows are open.
I found plans from WDFW and Cornell Lab of Ornithology, which I ended up using the WDFW plans. I made the box from a piece of western red cedar from the lumberyard, and with the help of my dad got it tied up to the tree. It has been up for a few years, although we only had an owl visit once to get shelter from a snowstorm. So far, it's mostly be home to the yard's resident squirels.
