The hike is nearly finished as you follow the white stakes to the saltwater lagoon. Remain vigilant. This small pond is a very busy neighborhood. Brown pelicans nest in the saltbrush. Other residents are finches, common stilts, herons, white-cheeked pintail ducks plus Galápagos hawks and mockingbirds. Until recently, this lagoon also delighted tourists with a colony of pink flamingoes. Unfortunately, they have recently left. Perhaps they will return if the pink shrimp larva increases again.
