This is the easternmost and geologically oldest island in the archipelago. All three species of boobies nest on the island as well as the endemic San Cristobal (Chatham) Mockingbird. A morning landing at Punta Pitt allowed us to hike to the interior. In the afternoon we landed on the beach at Cerro Brujo and found sleeping Sea Lions, Galapagos' Oystercatcher, and the endemic mockingbird.
