This is not very many ports for such a large feeder. This length prevents squirrels from hanging down from the top to reach the food. The bird feeder tube is 21 inches long with feeding ports at the bottom. It keeps squirrels away by spinning when the feeder detects the weight of the squirrel on the feeding perch. The Flipper is a battery-powered squirrel-proof bird feeder made by Droll Yankees. Classic Brands also owns/represents Stokes Select, More Birds, and Squirrel-X brands of bird feeders. It is Droll Yankees of Connecticut, whose parent company is Classic Brands, LLC of Denver, Colorado. The spinning bird feeder is a type of weight-sensitive squirrel-proof bird feeder. Here is one on Amazon that shows it on a tube-type feeder. And, again, chipmunks may not be heavy enough to trigger the mechanism. They hang from above or reach out from the side without touching the perch. They soon out-smart the closing feeder ports. Squirrels are very smart, acrobatic, and determined. When heavy squirrels press their weight on the perch to eat, the feeding ports close. Here is a link to one on Amazon with good reviews that is typical of the design.Īnother way bird feeders keep squirrels out is with weight-sensitive perches. Small squirrels can still get in, as well as chipmunks. These act to keep out larger squirrels and even larger jays, starlings and blackbirds. Some bird feeders have a wire cage surrounding them. And adding the chemical in hot peppers (capsaicin) to bird seed deters some squirrels, without impacting birds. Additionally, some foods such as safflower seed is less desirable to squirrels. Though not a bird feeder design, baffles can be added to poles below or cables above the feeder to make it more difficult for squirrels to reach feeders. But a determined squirrel will still get through to the seed. There are two main bird feeder designs to keep squirrels out of your bird feeder: cages and weight sensitive feeding port perches. In addition, squirrels may gnaw on plastic bird feeder parts, destroying them. When present, squirrels can eat a large volume of bird seed and take over a feeder so that birds cannot feed. A squirrel-proof bird feeder is almost an oxymoron. Keeping squirrels out of the bird feeder seems an impossible task.
