A bird feeder comprising of a free spinning plate guards to prevent unwanted pests such as squirrels from accessing the seed within the feeder. Whereas birds can feed while resting on perches which protrude outwardly from the bottom portion of the feeder, non-flying pest animals such as squirrels must approach the feeder along its outer periphery, traversing the plate guards in the process. As the pest tries to climb onto the feeder and access the seed, the plate guards spin; preventing the pest from having a stable footing and thus fall off the feeder. |
