Beautiful Bird Feeder, ready to hang. Constructed from Western Red Cedar or Pine shingles for the roof. Exterior grade ply-board for the walls, floor and underlying roof board. Kiln-dried hardwoods,pine and poly-resin for the details. Outdoor, non-toxic paint. With time, this feeder 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. There are no chemicals used in making these feeders that would be harmful to wildlife.
