发明名称 Squirrel proof bird feeder
摘要 A bird feeder having a lid latching mechanism which comprises L-shaped holes on the feeder's lid, and a wire handle having projections that orient above the lid. The projections in the handle align with the sides of the L-shaped holes to prevent the lid from being lifted from the bird feeder. A seed cover over the seed dispensing area is connected to a shaped wire perch via a through-hole. The perch acts as an actuator to close the seed cover, and is counter actuated by an extension spring, which attaches to the seed cover and feeder base.
