The Beach Haven Birdhouse is fully functional, with removable back walls for easy cleaning. The hole openings are designed to accommodate common cavity dwellers such as Wrens, Finches, Chickadees, Nuthatches and Titmice. The feeders will attract all types of wild birds. The houses and feeders are constructed of Western Red Cedar or Pine shingles for the roof, exterior grade ply-board for the walls, floor and underlying roof board and kiln-dried hardwoods, pine and poly-resin for the details. They are finished with outdoor, non-toxic paint. With time, all products will need to be refinished when left outdoors. The shingles (cedar) will patina to a silvery color and the piece will become weathered and distressed. $119. Buy here.
