Giant Galapagos tortoises grunt in distant highlands. Prehistoric marine iguanas spit their salty spray. Flightless cormorants and tiny penguins dart through the surrounding waters. Storm petrels walk across its surface and graceful red-billed tropicbirds screech across the sky. A new day in the Galapagos begins its wildlife symphony. With a Galapagos naturalist at our side, we set out each day in the early morning and afternoon, to remarkable ecosystems where the wildlife is most abundant and active. Inching our way past lounging iguanas and sea lions, scouting for breaching whales offshore and pink flamingos at hidden lagoons, we marvel at the strangeness of the Galapagos creatures on these desolate volcanic isles much as Charles Darwin did nearly two centuries ago.
