Bird Feeder for Outside, Squirrel Proof Bird Feeders for Outdoors Hanging

When the squirrel climbs onto the bird feeder, the spring will stretch and the feeding port will be blocked by the spring, making it difficult for the squirrel to obtain the seeds. Detail design: The four feeding ports are designed for birds to peck at seeds, and squirrels find it difficult or can only obtain very few seeds.
