Using model planes to scare away the birds
Jul 6, 10:56 AM (ET)

BEIJING (Reuters) - Chinese scientists have developed remote-controlled
model planes that can screech bird calls and emit bright, flashing lights to
scare wild birds away from airports, state media said Wednesday.
The flying "scarecrows" were expected to be more effective in frightening
birds away from runways and flight paths than previous experiments which
included cannon fire and blasting scary sounds from speakers on the ground,
Xinhua news agency said.
"By switching the plane models to the sounds of predators of birds currently
in residence near runways, the operator is very likely to dispel birds from
around airports," it said.
It did not say what would happen if a plane flew into one of the models.
In March, Beijing airport found that imported U.S.-made scream-machines
failed to scare away birds because they the "foreign language" of American
predators got lost in translation.
