Check out this great item that I found online.
Protect your bird seed from squirrels with the Eliminator Bird Feeder and Tree Hook from Wild Birds Unlimited.
When a squirrel touches the perch ring, its weight closes the seed ports, foiling its seed-stealing plot.
Fill up your bird feeder with this 5lb bag of Premium bird seed. (The Eliminator hold 3.5 quarts of seed)
