Cedar Peterson Style Blue Bird Houses---Makes a great Christmas gift--Made out of solid 1 inch cedar, assemble with screws. The top is angled down 23 degrees to shed water---the bottom is angled down 22 degrees to drain any moisture, and the front is angled forward 22 degrees for extra nesting space. Vent holes in the top of the sides to prevent overheating of the nest cavity. Designed for easy clean-out by removing two screws and the front door opens down. Solid maple entrance hole guard---one inch thick---helps keep racoons out. All edges are rounded over with a 1/4-inch radius. You will not find a Peterson style bluebird house like this for the money.
