In Baku, in recent years, there is a sharp reduction in the number of sparrows. These birds almost completely disappeared in the city center.
It will be superfluous to mention what an important role of sparrows play in the ecosystem. It is enough to recall what the state program for the destruction of Vorobyev in the framework of the “cultural revolution” of the Great Cordic Mao has led to China in China. Then in China, tens of millions of people were killed from hunger, and the country’s authorities were urgently organized by the bridge of living birds from other countries.
But what happened in the capital of Azerbaijan? Why did life in our city become unbearable for these little creatures? The leading scientist of the Institute of Zoology of Nana Abulfaz Tagiyev binds it with a number of factors.
According to him, the sharpness of the sparrows in Baku contributed to the disappearance of nesting sites, reducing feed, increase the number of raven and the increased noise level in the city.
Abulfaz Tagiyev noted that the sparrows could not have nests in new high-altitude houses, which were built up Baku. The fact is that the roof of the buildings are assembled from metal structures that are strongly heated in the sun.
The scientist reminded that the heart of Vorobyev beats 10-13 times faster than the heartbeat of an ordinary person and reaches 700-800 beats per minute. When the sparrow is in flight, this indicator only increases.
“from strong noise, which is plentious in our city, the sparrow can dramatically jump blood pressure. As a result, the bird dies,” said Tagiyev.
