On the Santa Cruz Island in the Galápagos, researchers carefully captured finches, measured their beaks, then marked them with colored leg bands for future identification before releasing them.

The researchers said that because of the links between beaks and song, an entirely new species of Darwin’s finches could evolve in response to six major Galapagos droughts.

The Darwin finches, a group of about 18 species of passerine birds, are well known for their wide diversity in beak form and function.

Earlier studies on finches established that their beaks adapt to changes in their ecological environments, including habitat loss and drought.
