Fortunately, there are more than a few ways to keep squirrels out of your bird feeder. For instance, you can use a squirrel-proof bird feeder like the Brome Squirrel Buster Plus Squirrel-Proof Bird Feeder to keep your bird seeds safe. The bird feeder is available on Amazon, and it has a weight-activated design. The bird feeder can hold nearly 5 pounds of seed at any given time. While it's always a good idea to comparison shop with some other top-rated squirrel-proof bird feeders, before making the final purchase, customers mostly seem happy with the Brome squirrel-proof bird feeder.
