Vehicle installed bio-acoustic bird dispersal system

Effecticve Bird Dispersal from airfields and surrounding areas


Scarecrow’s bio-acoustic bird dispersal systems are humane and inoffensive in their function, exploiting natural bird behaviour for their success. A new advanced storage technology, designed to further improve the well established efficiency of Scarecrow products, forms the basis of Premier 2020.

Premier 2020 offers effective airside bird dispersal using bio-acoustics; it is a highly effective bird dispersal system with the capability to upgrade to a complete data logging and analysis system.

Scarecrow Premier 2020 operates from 12 or 24v dc sources and has been designed to be vehicle installed to provide a complete bio-acoustic bird dispersal system when connected to scarecrow roof mounted loudspeakers; these will promote a vertical beam of sound reaching into the sky above to ensure distress calls are maintained until the subject birds have dispersed from the immediate area.


Upgrade to Scarecrow B.I.R.D. Tab™

The full facilities of the Scarecrow B.I.R.D. Tab™ system can be added at any future date, to display a database of bird recognition information, including full screen illustrations to aid species identification.

Scarecrow B.I.R.D. Tab™ establishes proof of dispersal procedures completed in real time, logging Operator, species, time and date; its inbuilt GPS function logs the vehicles airside position from where dispersal took place.

Equally, if a Scarecrow B.I.R.D. Tab™ Reporting Only system has been previously installed then adding the Premier 2020 upgrade kit to the vehicle will provide a full data logging and analysis system, combined with bird dispersal capabilities.

Both Premier 2020 and Scarecrow B.I.R.D. Tab™ are designed to fully interface.


Remote Control

A hand held remote control, providing all the features available from the Premier 2020 front panel can be connected to allow the 2020 processor to be stored under a vehicle seat, or elsewhere.
