This innovative design for your suet-loving birds. Thoughtfully designed, the Squirrel Buster® Suet squirrel-proof feeder rescues falling crumbs in its Crumb Port where birds recycle them, and it features mess-free suet loading–no more greasy fingers! With Suet, you’ll have frequent feathered guests without suet-loving squirrels diminishing your returns. The Suet feeder is also weight adjustable, so you have the option of fine-tuning your feeder to exclude larger birds as well.
