BIRDYELL-HAND

2.1

INTENDED USE

Your BirdYell-Hand has been specially designed as a professional tool, to be used by a
trained, qualifi ed, and specifi cally designated specialist (preferably certifi ed/authorised
internally at the operator's organisation).
The BirdYell-Hand 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 fl ee the area*.
The BirdYell-Hand device can be powered by type AA batteries or a 12 volts vehicle bat-
tery.
The BirdYell-Hand has proven to be successful in many different situations, scaring away all
kinds of nuisance causing birds. The device is effi cient on farm fi elds, horticulture plots, and
cereal storing facilities, cattle stables, country estates, landfi lls and industrial installations.
A frequent usage of the BirdYell-Hand will cause the birds to return less quickly after they
were scared away.
*Corvids, like magpies, jackdaws, crows, and rooks will at fi rst be attracted by these sounds,
to investigate where the sound come from.
