Bird feeder Squirrel Raccoon guard

Valley tin or furnace duct squirrel or raccoon bird feeder shield

Our sheet metal bird feeder pest protection shield before installation

We used a 20 inch wide piece of valley tin left over from roofing ricks brewery, but a six inch diameter 2 foot section of furnace duct would work great. Here it is shown just before we screwed it togeather in to a pipe shape.
