Took this Screech Owl picture at a friends house two winters ago. It was probably exploring this wood duck box for a nesting site. It did not nest there. Screech Owls are 7-10 in. tall and although fairly common , they are not seen often. Many years ago a family of Screech Owls was living at my in-laws house. Each night they would hunt, and behead the mice, and leave the bodies lying on the back patio of the house. Hunting was so good that they were only eating the high energy brains of the mice. They would roost in the spruce trees in the backyard and were so calm that I held by 5 year old daughter up and she touched one of the owls.
