Scientists use artificial intelligence to confirm that birds are more colourful near equator

Using artificial intelligence, scientists have confirmed that birds are more colourful near the equator. According to the study's author Christopher Cooney, ''We found that colourfulness was highest in birds from dense, closed forest habitats.'' "In vibrant rainforests, having colours that stand out from the crowd may help tropical species to distinguish themselves from others", he added. The researchers have proved a theory proposed by biologists Charles Darwin, Alexander von Humboldt, and Alfred Russel Wallace in 1850. After comparing the flora and fauna of northern Europe with the tropical region, they were all stunned.
