Brome Squirrel Buster Plus
The patented "Squirrel Buster™ system is truly squirrel proof! Openings in the bottom section of the feeder (shroud) align with seed ports, providing birds access to the seed. When a squirrel climbs onto the feeder, its weight automatically forces the shroud down, closing the seed ports. Squirrels and large birds are foiled but not harmed in way. Holds 3 quarts of seed. Weight adjustable to help control unwanted birds. Cardinal friendly. Dishwasher safe and Chew proof.
