After wailers failed to
chase away owls that pose a threat to the Thiruvananth-apuram airport, airport
officials are now pinning hopes on radio frequency technology.
Deccan Chronicle recently
reported that the Thiruvan-anthapuram airport witne-ssed a fresh problem of
bird hits at night. In the last one month, two incidents of bird-hits occurred
in the airport at night, and in both cases, owls were the villain.
In the wake of the
troubles caused by owls near the runway, airport officials have tried wailers
that produce sounds to chase away owls.
“The wailers were found
to be ineffective as the owls were seen to be returning minutes after the sound
was produced,” said airport director G. Chandramouli.
A private firm has
appro-ached airport officials with a radio frequency device which can give
alerts about the presence of any birds in specified regions.
“We have sought a
demonstration from the firm and if it is found effective, steps to acquire it
will be initiated,” said the airport director.
Meanwhile, steps like
sealing all rat holes along the boundary walls of the airport and pesticide treatment
are also being initiated to repel rats which cause the increased presence of
owls near the airport.
At present, airport
offici-als are carrying out physic-al checks along the runway before all
take-offs to en-sure that there are no owls.
