A bird feeder includes an electric circuitry for delivering a mild shock to squirrels attempting to eat seeds on a seed tray. A seed storage tube dispenses seeds on the surrounding seed tray, which is surrounded by walls forming a shell with windows providing access to the seeds. Window frames form electrodes having a first polarity and both a roof and porches beneath the windows form electrodes of a second polarity. Squirrels will complete the circuit between electrodes, while birds will be unaffected. A solar cell on the roof recharges a battery.
