Three years of field testing made this Squirrel-Proof! Squirrel Blocker Technology by Duncraft - 1" by 1" fencing and the distance to the 1/4" by 1/4" stainless steel wire feed tube - is the formula that stops squirrels from stealing your birdfeed.
The open flow-through bottom insures no seed collects to attract Squirrels. Birds perch all over the Blocker fencing and put their heads through it to pick a seed from the seed-saving mesh tube. You'll find that the seed lasts longer in this feeder -- birds take one black-oil seed at a time! And the squirrels just give up!
