(Bird Instinctive Reactive Dispersal)

Scarecrow Bio-Acoustic Systems is perhaps the largest specialist and the acknowledged leader in bio-acoustic bird control technology, the reason why their products are ‘preferred’ by airport and airfield operators and at other strategic sites; anywhere that the presence of birds can present a safety or health hazard.

Scarecrow bio-acoustic bird dispersal systems are humane and inoffensive in their function, exploiting natural bird behaviour for their success. Scarecrow use naturally occurring bird distress calls, usually causing no noise intrusion or disturbance to humans.


What is Atex Rated Scarecrow B.I.R.D. System™?

Scarecrow B.I.R.D. System™ is a well researched bio-acoustic bird dispersal system using natural species distress calls to create an environment appearing ‘hostile’ to birds.

It is intended for use where ATEX rated equipment is required where birds present a hazard to health and safety, or are a plain nuisance.

Scarecrow B.I.R.D. System™ is a fully automatic, random play system that is able to work without human intervention. Atex rated systems can be powered from 15v DC (100v/250) ac mains power.

There is a built in key pad to control the settings on the system, and it has an optional security pin access feature for additional safety. It is fitted with a light sensor for use when mounting the system outdoors. If mounting indoors, a timer can be used.

Scarecrow B.I.R.D. System™ can hold up to a maximum of 30 speakers, and by using variable volume and alternation between the installed speakers it creates a natural perception of predator movement.
