Rare Birds Kill Themselves Because of Noise
Two bustards, one of the endangered birds under top state protection, killed themselves by bumping the cage because of huge noise nearby recently in a zoo in Harbin, capital of northeast China's Heilongjiang Province.
They were not the only unlucky ones. Since last year when a construction work was started nearby, 16 rare bids in the Harbin Zoo had been killed by the noise, including 14 bustards and two cranes.
"The noise drive the birds into bad mood, they fly in chaos and many of them were bumped heavily by the iron balusters," said Tian Xiuhua, director of the research section of the zoo.
He said that the noise disturbed the normal life of birds and badly influenced their reproduction.
"A female crane recently broke up its own eggs, a white stork couple seem to forget mating," he said.
"They just need a quiet environment."
According to him, the zoo administration is now negotiating with the unit doing the construction to lower the noise.
