That’s what the scientist Charles Darwin wondered when he visited the island in 1835. He started to collect these birds to study them up close. He found out that even though these finches all look similar, there are actually thirteen different kinds on the Galápagos Islands. Each one of them has its own call, its own food and, most interesting to Darwin, a different kind of beak. Some were thick and strong, some narrow and needlelike, and others short or wide. Darwin guessed that the birds all came from the same ancestors.
They stopped flying because they didn’t need to escape. Over time, their wings grew weak, and they lost the ability to fly. But when people started arriving on the islands, they brought dogs and cats. Some of those dogs and cats became feral. They hunt the birds of the islands. And because these cormorants can’t fly away anymore, they are very easy prey. 43 Galápagos Sea Lion (Zalophus californianus wollebaeki) A female (left) and male sea lion 44 The Galápagos sea lion playfully nips the Galápagos penguin as it glides by in the water.
