A fun, exciting, entertaining, and 100% squirrel-proof feeder. The tube is 4-3/4" wide and constructed of UV stabilized polycarbonate for durability. The tube is also long enough so squirrels cannot reach down and get seed. Tube cap is metal for durability. Seed capacity is 4 quart. 4 feed ports are positioned around the tube for easy feeding by all birds. The excitement comes when squirrels sit on the perch. The weight of the squirrel puts the perch in a spinning motion not allowing the squirrel to feed. The motor is run from a rechargeable battery (recharger is included). Color: Green and clear. Guaranteed for life, including damage caused by squirrels.
