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
