Droll Yankee 21" Whipper 4 Port Squirrel Proof Bird Feeder

Curved perches designed with cardinals in mind. Birds, including cardinals, can perch and eat; squirrels on the perches cause them to collapse. Collapsible, mechanical perch rods are weight-activated using a patented design. Sturdy stainless steel wire will not rust. Metal cap fits snugly so that squirrels cannot pry it off. Seed tube is made of U.V. stabilized polycarbonate for durability. Lifetime warranty against squirrel damage.
