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.

Adaptive Radiation: Darwin's Finches There are now at least 13 species of finches on the Galapagos Islands, each filling a different niche on different islands.

It’s extremely hard to find fresh water on these isolated islands, but booby blood is packed with hydration. Over time, natural selection favored finches with sharper, longer beaks.
