Brome Squirrel Buster Plus Squirrel Proof Bird Feeder

The Brome Squirrel Buster Plus Squirrel Proof Bird Feeder features a truly squirrel proof design. Openings in the feeder base typically align with open seed ports allowing birds to access the feed, but when red and grey squirrels or large birds try to feed, the feeder base quickly drops to close access to the seed ports. Squirrels and large birds are prevented from feeding without being harmed in any way. The weight sensitive spring mechanism is completely adjustable to exclude different types of birds and squirrels. Simply remove the feeder cap and twist the transparent cartridge clockwise to increase the weight setting and counter-clockwise to decrease the weight setting. A handy chart comparing the weights of common birds and squirrels is included to use as a guide when adjusting the spring closing mechanism.. . This feeder has six feeding stations, adjustable perches with posi-grip, and an optional posi-grip cardinal ring. The cardinal ring perch offers cardinals a secure grip
