Bird Control and Dispersal

Scarecrow Bio-Acoustic Systems produce bird dispersal products incorporating natural bird distress calls that are humane and inoffensive in their function, exploiting natural bird behaviour for their success. If you are concerned about resolving Risk Management problems, we invite you to take a step forward to a new technology.

Leading the Industry

Scarecrow Bio-Acoustic Systems is the industry leader in the science of bio-acoustic bird dispersal and was originally a subsidiary of one of Europe’s largest commercial audio manufacturers, established in 1967.

 In 1990 Scarecrow became independent to allow focussed development in the field of airside bird dispersal, to capitalise on their specialist digital audio knowledge.The team of digital audio engineers and ornithologists comprising Scarecrow Bio-Acoustic Systems Limited have been in the business of designing, manufacturing and perfecting systems of bio-acoustic bird control since 1985, their products ‘preferred’ by airfields where birds present a hazard to flight safety.

Scarecrow is a privately owned UK Company. All products are manufactured to comply with ISO 9000 Quality Standards and European Safety and Noise Immunity Directives, including CE and E Approvals, RoHS and WEEE Directives. The Company aim to be ethical and helpful in all aspects of their work.

SCARECROW products, representing state of the art technology to fully meet the challenging task of Bird Strike Avoidance, are Approved and used by major civil airports and in military aviation throughout the world.

SCARECROW PREMIER 1500, the latest development from SCARECROW for airside vehicle installation, incorporates an RS232/485 port and will link with computer based software such as SCARECROW ISIS V3, to enable dispersal events to be data recorded: date, time, bird and location.

It is configured as a part of total safety management system, SCARECROW SIGMA a hand held mobile computer, will help airports improve safety, prove due diligence, ensure Compliance, manage risk and beat birdstrike hazards. SIGMA is directly connected to PREMIER 1500 for the purpose.

Handheld SCARECROW PATROL TWO is in use dispersing birds from Hangars and passenger areas inaccessible to vehicles.

Research and Development

Scarecrow research activity and continuing investment is not confined to ensuring call fidelity. Distress calls from new species are continually sought and trialled. Scarecrow research professionals have also dispelled the myth that powerful loudspeaker systems are always necessary for good dispersal. On the contrary, birds react best to high fidelity distress calls at sound levels that they aturally experience, provided that the calls start at a natural beginning, unique to Scarecrow digitally processed recordings.
Broadcasting at full volume may cause birds to move, because they are reacting as humans do when subjected to loud distorted noise, bangs, whistles, wailing sounds and other unnatural signals; the sounds simply disturb birds whilst they are still novel. They do not simulate a natural, hostile environment and they are therefore limited and short term in dispersal efficiency. In fact,such sounds could be prejudicial to flight safety.

The Scarecrow website contains many practical solutions and some guidance on what not to apply airside.
