Washinton: Many birds are shrinking in size due to the constantly changing climate in the changing season, but their wings are spreading more. This has been claimed in a new study assessing the dangers of climate change. Researchers at Michigan State University in the US have claimed this by analyzing a data set of 52 species of migratory birds that have fallen down as they collide with buildings in Chicago.

According to information from sources, during the study, he found that from 1978 to 2016, the body size of the birds of 52 species has decreased and there is a statistically significant decrease in 49 species. The results of this study have been published in a journal called Ecology. It has been told that during this period there are 40 species of birds whose wings have increased in size. Now the spread has been relatively more in this.

Experts say that the body size of these birds is decreasing due to rising temperatures. But it is certainly surprising that birds of only one species are not affected by this, but most of the birds have seen changes due to increasing temperature. Researchers said, "In the old study, many such possibilities were being expressed that birds of climate change are also having the most effect, which seems to prove to be true." The shrinking of the size means that for a long time birds are also calling global warming. Researchers said that the rate at which the heat of the Earth is increasing today if effective steps are not taken to stop it, it may be that many birds will cease to exist in the future. If this happens, it can also have a serious impact on the ecosystem.
