This feeder has multiple features to deter the pesky squirrels from robbing the seed from the birds. The feeder’s weight-activated system is calibrated to support the weight of birds but not squirrels. When squirrels try to gain access to the perches, the cage is pulled down, causing the decorative leaves to cover the ports. The feeder is all-metal with six feeding ports and U-shaped perches which allow multiple birds to dine at once. Powder-coated finish offers rust resistance for durability. Holds up to 2 lbs. of seed.
