Squirrel Buster Plus Squirrel-proof Bird Feeder - Large Capacity

Our review of the Squirrel Buster Plus finds it best suited to serious backyard birders who are tired of topping up seed every few days. The biggest reason to buy is simple: a patented weight-adjustable shroud that genuinely shuts access to feeding ports when a squirrel climbs on, protecting up to 5.1 pounds of seed. It is not a fashion piece but a practical, robust feeder that pays for itself by reducing seed loss and making routine filling and cleaning straightforward for those who feed mixed wild bird seed.

Key Features

• High capacity: Holds 3 quarts or about 5.1 pounds of seed so you refill less often and keep birds fed for longer stretches.
• Truly squirrel-proof openings: The shroud aligns with the feeding ports and closes under the weight of a squirrel, preventing theft without harming wildlife.
• Adjustable weight mechanism: A patented spring lets you set how much weight will trigger the closing action so target songbirds can feed while heavier animals are deterred.
• Durable construction: Made from UV-stabilized, chew-proof materials so the feeder resists weather and squirrel damage for extended outdoor use.
• Includes cardinal ring: Ships with a free cardinal ring that adds a larger perching option for cardinals and other medium-sized birds.
• Lifetime care: Manufacturer-supported customer service is available Monday to Friday with real-person assistance for setup and questions.

Who It's For

This feeder is aimed at homeowners and birding enthusiasts who want a long-term solution to seed loss from squirrels and larger birds; yards with persistent squirrel activity will especially benefit from the weight-sensitive shroud. It also suits people who prefer a higher-capacity feeder to reduce refilling frequency and those who want a feeder made from materials designed to stand up to weather and chewing.

It may be less appropriate for buyers wanting an ultra-compact or decorative feeder, or for those who need a simple ground-level feeder for non-perching seed-eaters. Very large birds may still cause trouble, and installers who need a pole adaptor should note that the pole adaptor is sold separately.
