Complete fixed system comprised of:
- 1 x Fully automatic and random play bird dispersal processor; incorporating 10
standard distress calls, built in keypad for setting controls, built in light sensor, and capable of
hosting up to 30 loudspeakers. Can be powered from 15v DC (100v/250v ac mains supply),
leisure battery, or Solar Power.
- 1 x in-built 30 watt Long-Line Transformer
- 1 x Power Supply; 15 Volt DC regulated switch mode; choice of EU/UK plug top or 12 Volt DC battery clips for powering from a leisure battery (specify when ordering)
- 4 x 1215/L IP65-rated 20 watt re-entrant horn loudspeaker, fitted with fully
adjustable stainless steel mounting bracket & 2m flex.
Standard calls: Herring Gull, Black Headed Gull, Starling, Rook, Crow, Pigeon, Jackdaw, Canada Goose 1, Canada Goose 2 and Birds of Prey
For additional distress calls please contact us on 01903 538 488
Additional speakers can be purchased up to a maximum of 10 speakers per channel (3 channels in total) giving a maximum total speaker volume per system of 30.
Free-standing, non-penetrating speaker mounts / stands (AD160) may also be purchased to help optimise the location of each speaker
A solar power kit can be purchased as an optional extra, which includes: battery & solar charge regulator in a weatherproof enclosure, solar panel, all necessary connecting cables and mounting hardware
The system has the following unique features
- Species-specific call selection from a pre-programmed list of 10 standard calls. User can select single or multiple calls which will play in sequence with a 60 second delay in between each species call.
- Randomised playback. If multiple species' calls are selected to play the system will automatically randomise the sequence in which they playback on each occasion to avoid habituation
- 3-channel playback rotation, the system has three channels, each able to support up to 10 speakers allowing the user to create 3-zones across which the sound will broadcast in a randomised sequence. Each channel will playback for 60 seconds in turn with a 60 second delay in between. This created the perception of a moving threat which heightens the anxiety in the target bird species as it is unable to locate the source of the distress call.
- Automated variable volume playback. The B I R D system will automatically raise and lower the volume of the playback during the 60 second output, up to a user pre-set maximum limit, to create the sense of a moving threat.
- Adjustable automatic day light sensor in built to the system to effect dawn-til-dusk operation, birds are active in daylight hours, the system will shut down 1-hour after sunset to avoid nighttime playback and habituation. Light sensitivity can be adjusted
- Remote light sensor available for when the control box has to be located indoors.
- Optional PIN code lock to prevent unwanted tampering / adjustment to the system
- LED display on box cover informs user of system status
- External key pad controls for quick and easy system programming and adjustment.
Scarecrow BIRD systems are designed for static, permanent installations where a large surface area needs to be protected from infesting birds using multiple sound sources.
Using multiple speakers ensures that the area to be protected can be done so effectively at optimum volume across the site without using eleveated sound levels from a single source, unlike other systems.
Scarecrow B I R D's in-built power 30 watt amplifier allows for extended speaker channel round of up to 200 linear metres per channel allowing for a maximum area coverage of 125,000 square metres.
Recommended areas of use:
- Industrial & commercial roofs
- Car park decks
- Sports facilities including playing fields & Astroturf pitches
- Aircraft hangars
- Exhibition halls
- Shopping centres
- Railway sheds, bus depots & stations
- Warehousing & distribution buildings
Point of Broadcast
Ideally, the point of broadcast should be from a high point – too low to the ground will
only limit the area covered, and therefore the success obtained.
Volume Levels
The volume of broadcast has to be at a natural level for the birds to identify the
broadcast as a natural call:
- Too loud – the broadcast will merely appear to sound like a noise, and no
reaction is likely.
- Too quiet - they simply will not hear the call, and again a dispersal reaction
is unlikely.
To attain what is perceived as a natural level for the target species, begin broadcasting
the system at the lowest volume level and then increase the volume until you see the
birds react to the call
Coverage
Total coverage the system is able to provide is dependent on many factors, not least of
which is the number of speakers utilised. Under normal circumstances we would not look
to design a system where any speaker(s) are required to broadcast in excess of 100m
distance.
Other dependent factors would include the lie of the land, prevailing weather conditions,
strength/direction of wind, other ambient noise, air temperature, shape/design of target
area and obstructions to sound broadcast.
Taking this into account, it is important to remember that the broadcast needs to sound
at a natural level to the birds for greatest effect – too loud or too quiet, will merely either
sound like a noise to the target birds and be ignored, or not heard at all.
