This squirrel proof bird feeder has openings in the wire shroud that align with the 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. 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 the 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.

Patented seed tube ventilation system.
Removable perches to further reduce access by Grackles.
Calibrated adjustable spring tension setting.
