SAW-WHET / SCREECH OWL HOUSE (17-3/4″h x 9-1/4″w x 11″d) Screech Owls and Saw-whet Owls have tough competition with other birds for natural cavities because they are so small. They eat night-flying insects and may occasionally snag other small birds. You may want to position this birdhouse away from the houses of other birds. The charming 7″ owls can become quite tame. This house comes complete with wood chips for nesting material. As with all our nest boxes, the design includes appropriate ventilation, drainage and opens for easy clean-out. Sustainably grown 1″ thick Eastern White Pine provides superior insullation. Hand crafted with pride in Maine.
