Brome Bird Care™ Squirrel Buster® Plus

I believe this feeder is the ultimate feeder. The length of the feeder makes it impossible for squirrels to get to the seed without causing the spring loaded cover to slide down over the food ports. The spring is adjustable so you can set it so bigger birds make it close if you wish. It is super easy to take apart for cleaning and holds 3 qts of seed.
