From Germany, proven in Europe for over 40 years.
  These birdhouses are made from a unique blend of 75% pine sawdust, bird clay and other natural materials formed and baked to provide a nesting home for birds that is healthy for them and which will last for 20 years or more in your garden.
 This remarkable material actually “breathes” like wood. Yet it is completely rotproof and the nontoxic brown paint on the roof and sides sheds water like a duck’s back. Resistant to damage by squirrels and raccoons. Front panel can be removed for cleaning. Seven models with entry holes specially sized for American birds.
