Feed birds (not squirrels!) and discourage bully birds with the revolutionary Squirrel-X5 squirrel-resistant bird feeder! If a squirrel tries to feed on any of the 6 spring-loaded perches, the X5’s integrated design shuts every port simultaneously, stopping racketeering rodents right in their tracks. 6 adjustable comfort perches provide bird selectivity, and their durable, round design attracts a wide variety bird species.
