Hey, backyard birdwatchers...
The Brome Squirrel Buster Bird Feeder is very effective against both red and gray squirrels. The opening in the bottom section aligns with the seed ports to provide only smaller bird access to the seed. The seed ports close when heavier birds or squirrels attempt to use it. This feeder keeps squirrels out... without harming them.
For added protection against those furry bandits... add a Squirrel Baffle or Dome to your bird feeder. It will protect your bird feeder, as well as repel squirrels.
