In Russia, the Vorobyov census has ended, starting two years ago. Each month and August, researchers and volunteers and volunteers carefully reviewed birds and sent reports to a website that was created specially “Sparrow on the Bushes”.
Why and how did Vorobyov think? This is RG RG by the Population Investigation Coordinator, Doctor of Science Study Igor Fefelov.
The scientist is sure: Observations of sparrows are necessary to pay attention over time whether there is no tendency to reduce their number or the disappearance of this species. The world has noticed the decrease in the number of these birds. Unclear reasons, that means the problem needs to be studied.
Igor Fefelov said. – First, attract attention to our nearest neighbors. And, second, set the basis to monitor what is happening to the Sparrow.
The calculation method is very simple: you need to find a vorobyov, take photos of them or record videos, then try to count. It is great to determine the type – Brownie or the field. Then you need to record your coordinates. And transmit all information by filling out the form on the “Sparrows on the Bushes” website.
This time, Vorobyov, 131 Observer, considered Vorobyov. Clear efforts have been included in account 1130 Vangs. Of the 82 participating areas of the Angle area in the 22nd place in the number of observers.
Irina Kleevtsova from Tulun with his daughter Margarita first went to consider Vorobyov.
– We walk along the streets and squares and watch. If we saw sparrows, they tried to come closer and take photos, Irina shared the strategy of Cesceptor of Peresaty. – And they counted at home, carefully researching the photos. It seems that all our sparrows are Brownies. At the end of their research, they decided to go to the city's private sector. This is a real expansion place for birds: on one of the fences we have counted 48 individuals. This is a record! The Klevtsov was discovered and described the ten sparrows.
119 350 Vorobyov was calculated in the August Census in Russia
Meanwhile, towns are alarms: Sparrows are becoming smaller. A resident of the center of Tatyana Semenova, moved to a new skyscraper, realized what she was missing there.
– At first, I decided what it seemed to me, then I listened … Sparrows didn't tweet here! Completely, she shared her sadness. – I started looking around, walking around the other yards. Not a single person! And in our old Khrushchev, they rushed in the entire herd. This means something, and actually, after all, they may disappear without attention.
Igor Fefelov confirmed that there was no sparrow in many city landscapes.
The yard birds where you can get food at a walking distance, he explained. – Although they are omnivorous, the chicks are only nourished by insects. And they bring prey all day. And because the leaflets are weak, this food is nearby. The diagram of “both goals and houses” – the sparrow disappeared.
Regarding the cause of the sudden silence in new buildings, the Ornithologist researchers have not yet released any version – because this is necessary for at least a few years, and not points, but completed. When they appear, it is difficult to say so far. In the end, the enthusiasts rewrite Vorobyov. Fortunately, there are more and more.
People started related to nature, Mr. Igor Fefelov said. – They feed the birds, worry if they find a chicken falling out of the nest, and rejoice when they have a feathered neighbor. Therefore, in the Population of Sparrow, more and more volunteers participated in each season.
Story
In the late 50s of the last century, a large -scale campaign to destroy sparrows opened in China. After that, the “experts” in the PRC calculated that in a year, each year, Sparrow ate about 4 kg of cereal, and if you remove them, it would be possible to feed 30-35 million. The result of this struggle is China's great hunger (1959-1961), according to different sources, from 15 to 45 million human lives. Due to the destruction of sparrows, insect followers, more crop destruction, propagated. As a result, birds and Canada were then imported from Russia and Canada from Russia.
