Defend your bird seed from undesirable critters with the Squirrel Shield Choice Tube Bird Feeder! The weight-sensitive seed shield collapses under the weight of a squirrel to block the seed ports should they try to jump from below. A quick locking roof secures the top of the bird feeder with a simple half-turn to ensure that squirrels are not able to reach in and gorge themselves on seed. The push-toggle roof provides quick access for easy refilling while hanging and doubles as a secondary defense to keep squirrels out! This bird feeder's innovative design allows the base to be removed by simply depressing 2 quick release tabs for a more thorough cleaning without the use of tools. Durable powder-coat metal roof and seed shield and a UV-stabilized tube make for a superior quality bird feeder that you and the birds will enjoy for years to come!
