Global warming has begun to reshape birds

Scientists said that the birds in the Amazon rainforest have become smaller, and their wings have lengthened. This is how birds adapt to changing environmental conditions.

The researchers drew their conclusions by looking at data on more than 15,000 individual birds. Comparison with data from the 1980s showed that almost all birds have decreased body weight, from an average of 30 grams to 27.6 grams. And that’s pretty significant.

Scientists explain the change as follows: the climate has become hotter and drier, and the birds have reduced the load on the wings. If the bird has a higher load on its wings, it needs to flap them faster to stay in the air, which requires more energy and produces more heat.
