If a squirrel tries to feed on any of the 2 spring-loaded perches, the X2’s integrated design shuts every port simultaneously. And if a squirrel tries to hang from the top, the X2’s hinged roof tilts under the weight of the squirrel, closing both ports to stop racketeering rodents right in their tracks! From Cardinals and Grosbeaks to Finches and more, songbirds love the X2’s long, broad perches. With a vintage burnt penny finish and a rugged metal frame, the Squirrel-X2 combines strength & style to bring you the ultimate in squirrel-resistant bird feeding and your best defense against squirrels!
