PRACTICAL TIPS
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:
o
Too loud - the broadcast will merely appear to sound like a noise, and no
reaction is likely.
o
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
•
The system is stated as providing coverage in each speaker direction to a distance of
100m.
•
This is dependent on a number of factors such as the lie of the land, prevailing weather
conditions, strength/direction of wind, other ambient noise, air temperature and
obstructions to sound broadcast.
•
As such, either a greater or lesser distance may be obtained.
•
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.
Effect on other wildlife
•
The calls broadcast are only recognisable by the target bird species, and therefore has
no lasting effect on other wildlife at all.
•
That is not to say that there will be no reaction – in some extreme cases, the broadcast
of a distress call may for example bring in a Hawk hoping to find some easy food.

•
One of the benefits of this system, if mounted on a pole/base unit, is that it can be
moved from location to location from time to time to enable different problem areas to
be tackled.
•
Whilst this is an option, it is recommended that a system should ideally remain in situ if
an area is required to be kept free of birds.
•
The concept of the system is to create the impression over time that the area is a
“threat area” and one therefore to avoid – so over time the bird numbers may even
reduce. This is achieved by the regular (but not too frequent) broadcast of the Distress
Call, which clearly cannot be achieved if the system is relocated.
