The truly squirrel-proof, patented technology.
The Squirrel Buster bird feeders operate with a weight-sensitive spring mechanism that closes feed ports when squirrels attempt to grab the bird seed. The spring is located inside the feeder, so the crafty squirrels can't tamper with it. Squirrels, as well as many heavier birds or chipmunks, are also foiled... but not harmed in any way. Save the bird seed for the birds you want to feed!
