This morning we explored the rocky shores of the remote island on San Pedro Mártir from our fleet of inflatable boats. Brown boobies and blue-footed boobies crisscrossed the air above us. Brown pelicans rested stately on the shoreline rocks, meticulously preening their feathers. Red-billed tropicbirds flew overhead occasionally, calling exuberantly with shrill voices as they swooped close to the rocky cliffs. The most amusing creatures we found were exuberant throngs of young California sea lions jumping, playing, and curiously peering at us from the sparkling waters around our boats.
