Climate change is making birds less colorful

Introducing: the lesser-spotted grayscale tit: Our latest climate change casualty may be the bright colors of our birds, a 15-year study on a bird known as the blue tit finds. The study concludes that a lack of rainfall and an increase in temperature has caused the climate-induced evolutionary change. The discoloration could have detrimental impacts on the longevity of the species, according to the lead author of the study. “Traits such as coloring function as signals to indicate to other individuals the quality of the specimen. They are decisive, for example, when it comes to breeding,” he detailed.
