Your BirdYell has been specially designed
as a professional birdscaring tool, to be
used by authorised personnel only who
have read and understood this manual.
The BirdYell device effectively scares birds
away by means of panic and/or alarm shrieks
of different bird species. Any birds close
to audible panic shrieks of other birds will
instinctively flee the area*.
The BirdYell device can be powered by
AA batteries or a 12 volt vehicle battery.
The BirdYell has proven to be successful in
many different situations, scaring away all
kinds of nuisance causing birds.
The device is NOT waterproof but is ideal for
use in grain stores, cattle stables, landfills and
industrial installations. If used outside, then
the BirdYell must be protected in a
waterproof enclosure.
The more frequently the BirdYell is used, the
more effective it is at keeping birds away
for longer.
*Corvids, like magpies, jackdaws, crows, and
rooks will at first be attracted by these sounds,
to investigate, but subsequently scared
and repelled.
