The phrase describes various strategies and techniques employed to prevent rodents, specifically squirrels, from accessing and consuming birdseed intended for avian species at feeding stations. Examples include employing physical barriers, modifying feeder designs, and utilizing seed types less attractive to squirrels.
Effective exclusion of squirrels from these feeders offers several benefits. It ensures that birds receive the intended nourishment, reduces seed waste, and diminishes the overall cost associated with maintaining feeding stations. Historically, the issue of unwanted wildlife consuming birdseed has driven innovation in feeder designs and deterrent methods.
