The Perky-Pet Squirrel-Be-Gone Wild Bird Feeder III features 9 feeding ports, U-shaped perches, 3 separate seed tubes that allow for a variety of seed types and holds 8 lbs. of seed. The interior seed tower is surrounded by rustic metalwork. The feeding ports have sturdy metal perches that allow birds to feed comfortably-but, when the squirrels perch on them, their weight causes the entire metal casing to slip down, completely blocking the feeding ports and their access to the seed. The nine perch/feeding station set-up, coupled with the anti-squirrel technology makes this feeder one of the most economical and convenient on the market! The three clear, seed tubes make it easy to monitor seed levels. Remember to clean your feeder once every two weeks with mild soap and water solution. Comes fully assembled with seed tray. Perky-Pet is the leading supplier of Wild Bird Feeders and Accessories. Perky-Pet Wild Bird Feeder models lure the bird in pursuit of seed—providing you with hours of joy as random wild birds flock to feed at your house.
