The Audubon Vista Squirrel-Resistant Bird Feeder is for the serious bird enthusiast. This rugged, double-sided feeder will attract a wide array of birds to your yard, while spring-activated perches work to keep squirrels away. This feeder features a simple and functional design. The two counter balance perches are adjustable to three positions and prove useful and effective at feeding the birds and not the squirrels. Holding up to 9 lb. of birds' favorite mixed seed, sunflower seeds, peanut halves or safflower, this large-capacity feeder requires less frequent filling. Stop birds from shoveling food out with the no-waste seed-saver baffle. It's made from a durable, green powder-coat steel top and bottom, acrylic body and a zinc-plated steel hanger. Lift the roof for easy filling and cleaning, and the acrylic body shows when the hanging bird feeder is empty. The overhanging roof and hopper keeps the seed dry and protected from the elements. The steel top and bottom withstands all types of weather and unwanted critters in your backyard for many seasons. Squirrels' weight on perch triggers a metal shield to cover the seed tray and shut off seed supply. Fully assembled, this anti-squirrel feeder hangs from tree branch or outdoor supports with included heavy-duty hanger.
