This morning, visit the CHARLES DARWIN RESEARCH STATION, established to help conserve the Galápagos’ natural habitats and protect the area’s famous giant tortoises. Spend some time in the town of Puerto Ayora before returning to the ship. At SOUTH PLAZA, wildlife includes sea lions, land iguanas, and hybrid iguanas, which are the result of a cross between male marine iguanas and female land iguanas. This is also a bird-watcher’s paradise, where you will see nesting swallow-tailed gulls, masked and blue-footed boobies, red-billed tropicbirds, frigatebirds, pelicans, and Audubon’s shearwaters.
