Abstract
The present invention is a mobile bird feeder which is resistant to invasion and destruction by squirrels. The feeder relies upon a combination of slippery side panels made of polished methylmethacrylate (Lucite.TM.) and a simple geometric configuration to prevent scaling by squirrels or similar small rodents. The transparent Lucite.TM. guard element provides protection from the weather elements, allows viewing of birds while approaching and feeding, presents an aesthetic appearance while presenting a movable target for the approaching birds.
