These feeders are 100% effective and ethical. The little birds are able to feed but the squirrels can't. The squirrel's weight shuts off the feeder ports, blocking access to food. Save money by wasting less seed!
This feeder is rust-proof and is ideal for holding seed mixes and straights such as sunflower hearts. If you are feeding peanuts, we recommend this feeder instead.
With over 5 million sold worldwide the Squirrel Buster technology has been stopping squirrels in their tracks for 20 years.
