I used to have a bird feeder, that turned into a bird house. I used a lamp shade to support a platform for seeds. Deer Antlers made good "branches" for birds to perch upon. A Horse Skull was the crown jewel. I painted it several times, and silver suited well. One year, a Wren made a nest inside the skull. Pictured here, a Cardinal sits proudly upon his newly acquired (albeit temporary) territory.
