It is not only 100% squirrel proof, but is also pest proof. Each feeding port is individually spring loaded, so if anything creature heavier than a songbird lands on any of the 3 perches, they will close the port and be denied access to the bird seed. Once the creature has alighted from the perch, the perch will simply return to its open position ready for the next songbird or pest.
Squirrel Proof and Pest Proof straight out of the box.
No calibration is required to make it squirrel or pest proof. Simply take the product out of the box, fill with seed via the easy to fill design, and then hang up. So simple to use. It is also easy to clean.
The bird feeder can hold 1.2lts of seed, so will not need topping up every day, and is backed by a 2 year guarantee.
