The Squirrel Buster Mini is an excellent entry-level squirrel proof feeder that combines effective squirrel-proofing technology with an low price tag. 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. The spring mechanism is calibrated at the factory to close at 4.0 oz./ 115 g. The smaller Red squirrels, as well as the larger Gray squirrels, are shut out at this setting. 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 Mini, permits humidity and hot air to escape through vents at the top of the feeder. The escaping hot 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. Show more
