This bird feeder is a high-energy bird feeder that birds cannot resist and is truly squirrel-proof. Its design features openings in the shroud that align with feeding ports, automatically closing when a squirrel's weight is detected, ensuring no harm to animals. With two-size meshes, the feeder allows for creative experimentation with various foods, helping to attract a wider variety of birds. Additionally, it promotes a no-mess, no-waste feeding experience, as foods like shelled peanuts, suet nuggets, and dried fruit don’t leave debris on the ground. The patented weight-adjustable spring mechanism ensures that only birds can access the food, resulting in savings on birdseed as squirrels are kept at bay.
