It’s a bird feeder -- and it’s the latest squirrel-deterring, seed bearing, bird feeding invention born of necessity. We dare you not to watch as the weight-activated feeding perch responds to a squirrel’s weight, immediately making a connection to an internal motor that sets the perch spinning. Squirrels cannot maintain their footing — and off they go. Batteries and a battery recharger are included. This Droll Yankees feeder is 21 inches long and has 4 feeding ports. 4 qt. capacity. Lifetime Warranty.
