Recycling bird seed feeder |
摘要 |
A bird feeder includes a housing containing a bird food hopper. The hopper feeds food into a tray. The tray is sandwiched between a roof and a floor, both of which extend outwardly from the tray to define a restricted vertical clearance duct for birds attempting access to the tray. Vertical partitions between the roof and floor define a restricted width clearance thereby forming a restricted clearance passageway to the tray between adjacent partitions and the corresponding roof and floor.
