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