Heritage Farms Original Absolute Squirrel Proof
Customers swear by the Original Absolute—it keeps out squirrels and large birds too. This rugged, all metal squirrel proof feeder has one spring activated perch. When a squirrel steps onto the perch, a metal shield immediately covers the seed tray, shutting off the seed supply. The perch is adjustable to three positions to allow light, medium or heavy birds on the perch. No matter what the adjustment, the Absolute will always block out squirrels. Depending on your settings, birds of a certain weight will also trip the perch. A chart of bird weights comes with the feeder, so you can choose the size birds you want to feed.
