The Squirrel Buster Classic Squirrel Proof Bird Feeder is an excellent way to keep squirrels away from your birdseed. A weight-based mechanism closes access to the seed ports when a squirrel climbs on, preventing them from getting to the seed. Birds are light enough that they do not activate the mechanism.

How It Works
Openings in the wire shroud align with seed ports and provide birds access to the seed. When a squirrel climbs onto the feeder, its weight automatically forces the shroud down, closing access to the seed ports. All squirrels and many large birds are foiled but not harmed in any way.

Patented Seed Tube Ventilation System
Transparent seed tubes are like greenhouses, they trap solar energy. Traditional seed tube cover designs block the escape of heated air. The patented seed Tube Ventilation system in squirrel Buster Classic permits humidity and warm air to escape through waterproof vents at the top of the feeder. The escaping air is replaced with fresh air entering the seed ports and openings on the bottom of the seed tube. The seed remains fresher and attracts more birds.

Perches Are Removable
The Squirrel Buster Classic can be converted into a clingers only feeder by removing the perches. The absence of perches will help deter large perching birds such as Grackles and Doves from using the feeder.
