More than a dozen birds can perch and feed from anywhere on the Squirrel-Proof Blocker fencing. The entire tube dispenses seed, yet squirrel paws and noses can not reach inside to get to the seed source! Fill with black oil sunflower and watch the birds perch on the fencing, putting their heads through to select one seed at a time from the stainless-steel mesh tube.
