A new research study has revealed that the bodies of birds around the world are shrinking due to climate change. The study found out that although the bodies of birds are gradually getting smaller, their wings are growing, something the researchers found out specifically in the tiniest of the species.
Scientists analyzed 4 Decades Data
The researchers of the study analyzed data of four decades gathered from migrating birds of Chicago and non-migrating birds of Amazon rainforest. Researchers noticed an astonishing evolution in the wings of smaller birds, showing their adaptation to the warmer temperatures.
Smaller Birds Are Evolving Fast
The research concluded that smaller birds are rapidly evolving due to shorter reproduction time scales. One other reason could be the huge population of smaller birds, which gives enough room for the birds to develop new traits to adapt to the changing climate, the research said.
