This Giant Seed Tray and Squirrel Guard from Droll Yankees mounts on a 1 inch pole and is held in place by a Complete Clamp (included). It catches seed spilled from above and is a great favorite of cardinals and other ground feeders. Its broadly curved edge prevents squirrels from getting to your feeders when placed below them and 4 feet or higher on the pole. May be filled with sunflower seed and cracked corn and used as an additional feeder! Type: Feeders Bird Species: Bird Location: Outdoor
