The Colonial Cottage Birdhouse in White is a true avian classic! Constructed of exterior grade ply-board, pine roof shingles and poly resin for detail and decorations. The swing-up mounting peg makes installation a snap. All the right stuff make this a fully functional birdhouse: 1. 25" opening, removable back wall, drainage, ventilation and an unpainted interior. Item Dimensions: 8. 75? H X 7. 875? W X 5. 875? D.
