Squirrel Buster Plus Squirrel-proof Bird Feeder w/Cardinal Ring and 6 Feeding Ports
The proven weight-activated squirrel-proof feeder that has worked for backyard birders for over a decade.
- Buy: Weight-activated shroud physically blocks access when squirrel weight is detected -- not a deterrent that can be defeated with persistence
- Adjustable tension dial lets you set the exact weight threshold to allow cardinals and larger birds while excluding squirrels
- Fully disassembles without tools for thorough cleaning, which most tube feeders cannot claim
Best For / Not For
Best for
- Backyards with persistent squirrel problems where other feeders have failed
- Buyers who want to attract cardinals with the included cardinal ring
- Anyone who wants a set-it-and-forget-it feeder that does not require squirrel baffles or poles
Not for
- Buyers who want the lowest possible upfront cost
- Very light birds like goldfinches if tension is set too high
Key Details
How the Weight-Activated Mechanism Works
The Squirrel Buster Plus uses a weighted shroud that slides down over the feeding ports when sufficient weight is applied to the perches. When a squirrel lands and grabs a perch, the combined weight triggers the shroud to drop, physically blocking access to the seed. The moment the squirrel leaves, the shroud returns to the open position. There is no way to override this mechanism through persistence or repeated attempts.
The adjustable tension ring at the bottom of the feeder lets you fine-tune the trigger weight. Set it light and the shroud drops with moderate bird weight, useful for excluding larger nuisance birds like starlings or grackles in addition to squirrels. Set it heavier and smaller birds like chickadees and finches feed freely while squirrels are still excluded.
Maintenance and Longevity
The feeder disassembles into its component parts without tools, which makes thorough cleaning practical rather than a reason to skip it. Wet seed and mold build up inside tube feeders and can make birds sick. The Squirrel Buster's tool-free breakdown means you can run the parts through warm soapy water and rinse completely, something impossible with feeders that cannot separate at the base.
Pros and Cons
Pros
- Weight-activated mechanism physically closes ports rather than just deterring squirrels
- Adjustable tension accommodates different bird sizes at the same feeder
- 6 ports and 5.1-pound capacity reduces refill frequency
- Fully disassembles for deep cleaning
- Cardinal ring included to attract larger perching birds
Cons
- Higher upfront cost than basic tube feeders
- Pole adaptor sold separately for pole mounting
Bottom Line
Buy the Squirrel Buster Plus if squirrels have already defeated your other feeders. The weight-activated mechanism is not a deterrent -- it physically cuts off access. Worth the premium if you want a feeder that actually solves the problem.
