Power authority tries to scare birds off wires with distressing sounds

THE Jiading District power supply authority has installed 16 bird repellers on some electric wires in a trial to prevent the lines from being damaged by birds.

The ultrasonic repellers are designed to expel birds by frightening them with sounds, the local Jiefang Daily reported today. The birds are able to understand the meaning of the sounds, which include the calls of their predators and their distress signals, so they will disperse quickly, officials said.

The electric wires have long been popular places for birds to build nests because of their stable structure and heat. The branches and iron wires the birds take to the electric wires can cause power interruptions and lead to security problems, the report said.

Nearby residents will not be disturbed because people cannot hear the sound waves, according to officials.

An increasing number of birds are spending their summer in the city, the report said.
