Catching Darwin's Finches on the Galápagos Islands

Early morning on the Galápagos Islands and Jaime Chaves is catching Darwin’s finches, endemic to these islands, in order to continue decades of work studying the size of these birds' beaks. The beaks are changing shape and size, not over millions of years but from one generation to the next, and now scientists like Jaime are studying the role humans are playing on the lives of these birds.
