Abstract
Pfeifer's bird-control apparatus was modified and tested
in 1967. Several safety features were incorporated. Also,
an industrial timer was added as an interrupter to break
the circuit from a high voltage transformer at regular,
short intervals providing the arcing and snapping needed
in a dry climate.
