Over a million happy clients (and well-fed birds) confirm that the patented Squirrel Buster™ system is truly squirrel proof! Openings in the bottom section of the feeder (shroud) align with seed ports, providing birds access to the seed. When a squirrel climbs onto the feeder, its weight automatically forces the shroud down, closing the seed ports. Squirrels and large birds are foiled but not harmed in way.

The Closing Mechanism: Use the feeder with the factory setting before making any adjustments. A small red squirrel, 4 oz./115g, will trigger the closing mechanism at this setting. To increase the adjustment setting, rotate the transparent cartridge clockwise. The red line will move down from the previous setting. This increases the weight required to close access to the seed. To decrease the adjustment setting, turn the cartridge counter clockwise. The red line will move up from the previous setting. This decreases the weight required to close access to the seed. Large capacity - holds up to 2.4 kg (5.2 lbs) of seeds. Quebec design and winner of "Best New Product" at Birdwatch America.

You can install this feeder on top of a one-inch pole with the Squirrel Buster Plus Pole Adaptor.  

Keep your seeds dry and away from rain and snow with the Squirrel Buster Plus Werather Guard. 


-Detachable Component System™

Squirrel Buster Plus™ components are designed to be assembled and dismantled easily by hand, without tools, and to fit into your dishwasher.

-Dishwasher Safe Bird Feeder™

Clean feeders are as important to wild birds as clean dishes are to humans. Grimy bird feeders can be a source of illness that can be fatal for birds. With squirrel Buster Plus™ detachable components it is effortless to provide the birds you love with a safe and healthy feeder. Regular cleaning of your bird feeder is essential and should never be delayed. Spread the word about clean, safe feeders.

-Seed Tube Ventilation System™

Damp and decaying seed decreases bird traffic and can spread disease. Most transparent bird feeder seed tubes trap solar energy just like a greenhouse. The air in squirrel Buster PlusTM rises and escapes through patented water-proof vents at the top of the feeder. The escaping, heated air is replaced by fresh air entering through the seed ports at the bottom of the tube. The birdseed remains fresh, attracting more birds.

-Perching Options Using Adjustable Posi-Grip Perch™

Thick, adjustable-length perches with textured surfaces provide a secure and comfortable grip for birds. Attract small birds such as Chickadees and Finches (while deterring larger birds like Grackles and starlings) by shortening the perches. Perches can also be extended just enough to attract medium-sized birds including Grosbeaks and Woodpeckers. You can exclude large nuisance birds such as Grackles, starlings, and Doves by using variable length perches and the adjustable spring mechanism.

-Cardinal Ring System™

The Squirrel Buster Plus™ can be used with or without the Cardinal Ring System™, an optional posi-grip ring designed especially for Cardinals. Cardinals prefer to grip a thick-textured perch and, because it’s awkward for them to turn their short necks to feed, they prefer to face their food source directly. The Squirrel Buster Plus™ Cardinal Ring System™ allows Cardinals to eat facing the seed from a secure and comfortable perch. These Cardinal-friendly feeding features combined with a bush-level location make Squirrel Buster Plus™ very inviting to our scarlet friends.


Your Squirrel Buster Plus™ squirrel-proof bird feeder is guaranteed to be free of material or manufacturing defects. The factory warranty applies when this product is used according to manufacturer’s instructions and for the lifetime of the original owner. Cosmetic scratches from squirrels or damage from raccoons, bears or other animals are not covered by warranty.
