摘要：
A tubular bird feeder for seed includes a seed metering valve above the feed holes which may be operated manually, or by a battery powered motor where the battery is charged by a solar cell and the motor responds to a remote control device from the indoors. The perches at the feed holes are made to suddenly buckle when too big of a creature alights thereon. A easy refill procedure uses a swing away cap.
