The Bird Gard is a programmable electronic bird repeller that uses a variety of species specific distress signals and predator calls to send a "danger" alert to other pest birds in the area. The BirdGard is ideal for spot dispersal of flocking birds in small areas.
These bird control devices have:
On-off and volume control
A "time off" phase between sounds
A day-night 24 hour switch
Plugs into 110 volt power outlet
The Standard BirdGard Pro bird repeller has the following programmed sounds: starling, robin, house finch (sparrow), ring-billed gull, grackle, sharp-shinned hawk, blue jay, erd-winged blackbird.
The Marine Bird Gard Pro II bird deterrent has six common gull species plus cormorant and marsh hawk sounds programmed.
