发明名称 Flip-flop bird feeder
摘要 An improved bird feeder, having a common "Mason" jar to act as a hopper for storing birdseed, a trough for holding seed and to provide a perch for feeding, a cord for suspending the trough and attached jar from a tree, and a support for preventing the inverted and suspended jar from pivoting downward when the feeder is in use. The support is slideably received on the cord, so that the support can be quickly and easily engaged or released from the jar.
